Nutritional Intervention Improves Muscle Mass and Physical Performance in the Elderly in the Community: A Systematic Review and Meta-Analysis.

Nutritional supplements have been extensively used as health interventions for the elderly. However, with the spread of COVID-19, no consensus exists on whether nutritional interventions could improve muscle mass and physical activity in community-dwelling older adults. To conduct a systematic review and meta-analysis to explore the effects of different nutritional interventions on muscle mass and physical performance in the elderly, we searched PubMed, Web of Science, Elsevier, and Cochrane databases from their founding dates to December 2023. The meta-analysis was performed using RevMan5.3 software. Only randomized controlled trials (RCTs) were considered, and the overall mean difference (MD) or standardized mean difference (SMD) with 95% confidence interval (CI) was calculated. There were 33 studies comprising 3579 elderly persons meeting the inclusion criteria. Comprehensive analysis suggested that the intervention effect of fat-free mass (FFM), appendix skeletal muscle mass (ASMM), handgrip strength (HGS), gait speed, and short physical performance battery (SPPB) score was higher in the nutritional supplement group than in the control group. The results of subgroup analysis demonstrated that protein supplementation (SMD = 0.82, p < 0.0001) had an optimal effect on ASMM (SMD = 0.89, p < 0.0001) and FFM (MD = 2.09, p < 0.0001) in the elderly. Vitamin D supplementation (SMD = 0.52, p < 0.0001) had a marginal effect on ASMM, and energy supplementation (SMD = 0.39, p = 0.0005) had the lowest effect. Moreover, nutritional interventions had the most significant impact on HGS (MD = 1.06, p < 0.0001) and TUG (MD = 0.14, p < 0.0001) in individuals aged 65-75 years old, with positive effects on FFM (MD = 1.62, p < 0.0001) and HGS (MD = 0.82, p < 0.0001) when compared to healthy elderly individuals, and had greater effect on ASMM (SMD = 0.69, p < 0.0001) than on the elderly with sarcopenia. Nutritional supplements can enhance muscle mass and physical performance in the elderly, while protein is recommended for muscle function. The golden period for implementing nutritional interventions to improve muscle function is before the age of 75 years. However, the impact of nutritional interventions varies with age and population. Given the limited evidence on nutritional interventions, more detailed and high-quality studies are highly warranted in the future.

EFFECT OF SAQ TRAINING WITH &amp; WITHOUT CARBOHYDRATE SUPPLEMENTATION AMONG ELITE FOOTBALLER'S SPEED

The main objective of the current study was to evaluate the changes in performance (speed) through SAQ training and carbohydrate supplementation of 08 weeks intervention. The study was conducted in the vicinity of Punjab University, Lahore. Participants (n=16) were selected through the inclusion criteria which included elite footballers and the participants were divided into two groups which were groups (A) and (B). Hypotheses of this study were: H0 1 There is no significant difference between the pre-test of group A (speed) and the pre-test of group B (speed). Ha 2 There is a significant difference between the pre-test of group A (speed) and the post-test of group A (speed). Ha 3 There is a significant difference between the pre-test of group B (speed) and the post-test of group B (speed). Ha 4 It is hypothesized that there is a significant difference between training with the Supplementation group (A) and Training without the Supplementation group (B). Group (A) was allowed to follow the 08-week exercise plan (intervention) and carbohydrate supplementation. Only group (B) was allowed to follow the 08-week exercise plan (intervention). Descriptive statistics, means and standard deviations were calculated. The inferential statistics and different tests including paired sample t-test and independent samples t-test were applied to calculate the differences in performance of all studied groups. The data was analyzed and evaluated statistically using Version 22 of IBM SPSS (Statistical Product and Service Solutions) software. The means (with standard deviation) of the speed tests of training with carbohydrate supplementation group (A) and the means (with standard deviation) of the speed tests of training without carbohydrate supplementation group (B) were compared. This study confirms that there was not a significant difference between groups (A) and (B) before training and carbohydrate supplementation. There was a significant difference in speed in, the pre-test of the group (A) compared with the post-test, followed by SAQ Training with carbohydrate supplementation. On the other hand, there was also a significant difference in speed, in the pre-test of group B compared with the post-test, followed by SAQ Training only. The study confirmed that there was a significant change in the speed of footballers' training with carbohydrate supplementation group (A) compared to training without carbohydrate supplementation group (B), after 08 weeks of intervention.

A prospective and observational study to assess the efficacy of pregabalin versus Gabapentin in relieving early post operative neuropathic pain with respect to clinical and functional outcomes in patients undergoing open lumbar discectomy surgery

Background: Post-operative neuropathic pain is one of the most dreadful complications following lumbar spine surgeries. Owing to the similarities in the pathophysiological and biochemical mechanisms underlying epilepsy and neuropathic pain, many anti-epileptic drugs (AEDs) like pregabalin and gabapentin are being used in the treatment of post-operative neuropathic pain. Methods: This prospective and observational study included a total of 60 patients out of 261 patients undergoing lumbar discectomy surgery, who postoperatively had neuropathic pain as diagnosed with LANSS score; and were randomly divided into pregabalin (n=30) and gabapentin (n=30) supplementation groups, and the efficacy was compared with respect to visual analog scale (VAS) score (clinically) and Oswestry disability index (ODI) score (functionally) at pre-operative and post-operative follow-ups; and also, total analgesia consumed. Results: No statistical differences were observed between any of the demographic variables and surgical levels operated upon between the two groups. Both the groups showed significant improvements in clinical (VAS) and functional (ODI) outcome as compared to pre-operative status. Leeds assessment of neuropathic symptoms and signs scale (LANSS) score was significantly increased in both the groups postoperatively till the 3rdmonthfollow-up, after which there was a significant decrease in the score. The Pregabalin group showed significant (p&lt;0.05) improvement in VAS and ODI scores at the post operative 1st, 3rd, and 6th month, as compared to the gabapentin group; however, at other follow-ups the difference was insignificant. Total analgesia consumed was significantly higher in the gabapentin group. Conclusions: Our study concluded that both pregabalin and gabapentin are highly effective in the treatment of early post-operative neuropathic pain; showing encouraging clinical and functional improvements. Pregabalin had significantly better outcomes on short-term follow-ups; however, on longer follow-ups, both had similar beneficial outcomes. Pregabalin supplementation showed a significant analgesia-sparing effect as compared to gabapentin.

Low-dose daily folic acid (400 μg) supplementation does not affect regulation of folate transporters found present throughout the terminal ileum and colon of humans: a randomized clinical trial

BackgroundFolic acid supplementation during the periconceptional period reduces the risk of neural tube defects in infants, but concern over chronic folic acid exposure remains. An improved understanding of folate absorption may clarify potential risks. Folate transporters have been characterized in the small intestine, but less so in the colon of healthy, free-living humans. The impact of folic acid fortification or supplementation on regulation of these transporters along the intestinal tract is unknown. ObjectiveThe objective was to characterize expression of folate transporters/receptor (FT/R) and folate hydrolase, glutamate carboxypeptidase II (GCPII), from the terminal ileum and throughout the colon of adults and assess the impact of supplemental folic acid. MethodsIn this 16-wk open-labeled randomized clinical trial, adults consumed a low folic acid-containing diet, a folate-free multivitamin, and either a 400 μg folic acid supplement or no folic acid supplement. Dietary intakes and blood were assessed at baseline, 8 wk, and 16 wk (time of colonoscopy). Messenger RNA (mRNA) expression and protein expression of FT/R and GCPII were assessed in the terminal ileum, cecum, and ascending and descending colon. ResultsAmong 24 randomly assigned subjects, no differences in dietary folate intake or blood folate were observed at baseline. Mean ± SD red blood cell folate at 16 wk was 1765 ± 426 and 911 ± 242 nmol/L in the 400 and 0 μg folic acid group, respectively (P < 0.0001). Reduced folate carrier, proton-coupled folate transporter, and folate-receptor alpha expression were detected in the terminal ileum and colon, as were efflux transporters of breast cancer resistance protein and multidrug resistance protein-3. Other than a higher mRNA expression of FR-alpha and GCPII in the 400 μg supplement group in the ascending colon, no treatment differences were observed (P < 0.02). ConclusionsFolate transporters are present throughout the terminal ileum and colon; there is little evidence that a low dose of folic acid supplementation affects colonic absorption.This trial was registered at clinicaltrials.gov as NCT03421483.

El efecto del tratamiento de hierro en pacientes con insuficiencia cardiaca e insuficiencia de hierro. Un metaanálisis de ensayos aleatorizados

IntroductionApproximately 45% of patients with heart failure had iron deficiency for the rest of their lives. ObjectiveTo determine the effect of iron treatment in patients with heart failure and iron deficiency or anemia. Materials and MethodsThe studies were selected in: PubMed, Scopus, Cochrane and Google Scholar, from the beginning of June to July 2023. The selected articles that met the inclusion criteria, the relevant information of the studies were collected according to the selection variables and were recorded in the Revman 5.0 program of the Cochrane collaboration. The primary outcome was composed of hospitalization for heart failure or cardiovascular death. ResultsOf the 7 included studies, 6717 patients were obtained, the average age was 70 years with a predominance of the male gender (57%). The primary outcome was lower in patients in the control group compared to the placebo group (OR, 0.62; 95%CI, 0.54-0.70). The 6-minute walk test (6-MWT) was improved in the iron-supplemented group compared to the placebo group (OR, 0.79; 95%CI, 0.64-0.98). Adverse events were fewer in the iron supplement group compared to the placebo group (OR, 0.78; 95%CI, 0.67-0.91). ConclusionIn this meta-analysis of randomized controlled trials, the effect of iron supplementation is found to reduce the incidence rate of hospitalization for heart failure or cardiovascular death. In addition to a reduction in adverse events, such as gastrointestinal and neurological disorders, it also improves 6-MWT.

Supplementing semen extenders with a combination of phosphorus and vitamin B12 Improves post-thawed cryopreserved rooster semen quality.

Semen cryopreservation is an important technique for preserving the genetic material of numerous species. However, frozen semen is highly susceptible to sperm DNA damage and reduced motility, resulting in decreased fertility. The standard method for cryopreservation and several approaches have not been elucidated. This study aimed to determine the effects of supplementing rooster semen extender with a combination of phosphorus and vitamin B12 on cryopreserved semen quality. Semen was collected weekly via dorso-abdominal massage from 57 Burmese × Vietnam-crossbred Thai native roosters aged 1-3 years. In total, 139 semen samples were collected, pooled, and diluted to 200 million sperm per dose. The pooled sample was divided into six experimental groups: a control group (0.00%) diluted with modified Beltville Poultry Semen Extender (BPSE) and five treatment groups diluted with modified BPSE supplemented with phosphorus and vitamin B12 at concentrations 0.02, 0.04, 0.06, 0.08, and 0.10%, respectively. The semen samples were frozen and evaluated at 0, 15, and 30 min after thawing. Sperm kinematic parameters were determined using a computer-assisted sperm analysis system. Sperm quality was evaluated by measuring sperm viability, mitochondrial activity, acrosome integrity, and plasma membrane integrity. Statistical analyses were performed using a general linear mixed model (MIXED) in SAS. Factors in the statistical model were experimental groups, time after thawing, and interaction between experimental groups and time after thawing. Total and progressive motilities were greater in semen supplemented with 0.04% phosphorus and vitamin B12 compared with those in the control (p < 0.05). At 15 min post-thawing, VCL, VAP, and HPA in the 0.04% phosphorus and vitamin B12 supplementation group was greater than that in the control (p < 0.05). Phosphorus and vitamin B12 supplementation did not affect sperm kinematics at 0 and 30 min after thawing (p > 0.05). All the sperm parameters that were tested for the 0.04% phosphorus and vitamin B12 supplementation group in modified BPSE were the highest at all the timepoints after thawing. Thus, supplementing frozen semen extender with 0.04% phosphorus and vitamin B12 increased sperm motility, sperm kinematic parameters, and sperm quality.

Prospective Randomized, Double-Blind, Placebo-Controlled Study of a Standardized Oral Pomegranate Extract on the Gut Microbiome and Short-Chain Fatty Acids.

Punica granatum L., commonly known as the pomegranate, is an abundant source of polyphenols, including hydrolyzable ellagitannins, ellagic acid, anthocyanins, and other bioactive phytochemicals shown to be effective in defending against oxidative stress, and has immunomodulatory activities. Ellagitannins, and their hydrolyzed product ellagic acid, interact with the gut microbiota to yield secondary metabolites known as urolithins that may have health benefits. The objective of this study was to determine the effects of supplementation with a standardized punicalagin-enriched pomegranate extract, Pomella® (250 mg), on the gut microbiome, circulating short-chain fatty acids, and gut microbial-derived ellagitannin metabolite urolithins. A randomized, double-blind, placebo-controlled study was conducted over 4 weeks on healthy volunteers aged 25-55 years. Subjects were randomly assigned to receive either an oral supplement containing 75 mg of punicalagin or an oral placebo. Stool sample collection and venipuncture were performed to analyze the gut microbiome, SCFAs, and urolithin. There was no significant change in the gut microbial diversity in both cohorts after 4 weeks of intervention, but there was a significantly increased relative abundance of Coprococcus eutectus, Roseburia faecis, Roseburia inullnivorans, Ruminococcus bicirculans, Ruminococcus calidus, and Faecalibacterium prausnitzii. Pomegranate extract (PE) supplementation led to the augmentation of circulating propionate levels (p = 0.02) and an increasing trend for acetate levels (p = 0.12). The pomegranate extract (PE) supplementation group had an increased level of circulating urolithins compared to the placebo group (6.6% vs. 1.1%, p = 0.13). PE supplementation correlated with shifts in the gut microbiome and with higher circulating levels of propionate and acetate. Further studies should explore the implications in larger cohorts and over a longer duration.

Chitosan oligosaccharide improves intestinal function by promoting intestinal development, alleviating intestinal inflammatory response, and enhancing antioxidant capacity in broilers aged d 1 to 14

This study was conducted to investigate the effects of chitosan oligosaccharide (COS) supplementation on intestinal development and functions, inflammatory response, antioxidant capacity and the related signaling pathways in broilers aged d 1 to 14. A total of 240 one-day old male Arbor Acres broilers (40.47 ± 0.30 g) were randomly allotted to 4 groups, and each group consisted of 6 replicate pens with 10 broilers per replicate. Broilers fed a basal diet supplementation with COS at 0 (CON group), 200 (COS200 group), 400 (COS400 group), and 800 mg/kg (COS800 group) for 14 d, respectively. Broilers in the COS supplementation groups had no significant effects on growth performance. Compared to the CON group, dietary COS supplementation increased (P < 0.05) the relative weight of duodenum, jejunal lipase activity, duodenal and ileal villus surface area, and lower (P < 0.05) ileal amylase and alkaline phosphatase activity, and crypt depth. The expression level of duodenal glucose transporter 1 (GLUT1), Na+-glucose cotransporter 1 (SGLT1), peptide transporter 1 (PepT1), occludin, zonula occludens-1 (ZO-1), toll-like receptor 4 (TLR4), myeloid differentiation factor 88 (MyD88), and interleukin-10 (IL-10), jejunal SGLT1, PepT1, occludin, tumor necrosis factor-α (TNF-α), and ileal SGLT1, PepT1, and fatty acid binding protein 1 (FABP1) was upregulated by COS. However, the expression level of duodenal FABP1 and TNF-α, jejunal GLUT1, ZO-1, TLR4, MyD88, nuclear factor kappa-B p65 (NF-κB p65), and IL-1β, and ileal GLUT1, NF-κB p65, and IL-1β was downregulated by COS. Furthermore, dietary COS supplementation increased duodenal catalase (CAT), glutathione peroxidase (GSH-Px), and total superoxide dismutase (T-SOD) activity, jejunal CAT and T-SOD activity, upregulated the expression level of duodenal nuclear factor-erythroid 2-related factor 2 (Nrf2), CAT, glutathione peroxidase 1 (GPX1), and copper and zinc superoxide dismutase (Cu/Zn SOD), jejunal CAT, and ileal Nrf2, CAT, and GPX1. These results suggested that COS could promote intestinal development and functions in broilers aged d 1 to 14, which might be mediated by alleviating intestinal inflammatory response and enhancing antioxidant capacity.

The effect of Saccharomyces boulardii supplementation on Helicobacter pylori eradication in children: a systematic review and meta-analysis of Randomized controlled trials

BackgroundIt is unclear whether Saccharomyces boulardii (S. boulardii) supplementation in standard triple therapy (STT) is effective in eradicating Helicobacter pylori (H. pylori) infection in children. We therefore conducted a meta-analysis of randomized controlled trials (RCTs) to assess the effect of S. boulardii supplementation on H. pylori eradication in children.MethodsWe conducted electronic searches in PubMed, Embase, the Cochrane Library, China National Knowledge Infrastructure and Wanfang database from the beginning up to September 2023. A random-effects model was employed to calculate the pooled relative risk (RR) with 95% confidence intervals (CI) through a meta-analysis.ResultsFifteen RCTs (involving 2156 patients) were included in our meta-analysis. Results of the meta-analysis indicated that S. boulardii in combination with STT was more effective than STT alone (intention-to-treat analysis : 87.7% vs. 75.9%, RR = 1.14, 95% CI: 1.10–1.19, P < 0.00001; per-protocol analysis : 88.5% vs. 76.3%, RR = 1.15, 95% CI: 1.10–1.19, P < 0.00001). The S. boulardii supplementation group had a significantly lower incidence of total adverse events (n = 6 RCTs, 9.2% vs. 29.2%, RR = 0.32, 95% CI: 0.21–0.48, P < 0.00001), diarrhea (n = 13 RCTs, 14.7% vs. 32.4%, RR = 0.46, 95% CI: 0.37–0.56, P < 0.00001), and nausea (n = 11 RCTs, 12.7% vs. 21.3%, RR = 0.53, 95% CI: 0.40–0.72, P < 0.0001) than STT group alone. Similar results were also observed in the incidence of vomiting, constipation, abdominal pain, abdominal distention, epigastric discomfort, poor appetite and stomatitis.ConclusionsCurrent evidence indicated that S. boulardii supplementing with STT could improve the eradication rate of H. pylori, and concurrently decrease the incidence of total adverse events and gastrointestinal adverse events in children.

Sweet-type star fruit supplementation controls oxidative stress status and enhances the community walking capacity among elderly Thai

BackgroundSweet-type Star fruit (SF) (Averrhoa carambola L.) is seasonal and more available for purchase in many markets in Thailand, when compared to the sour-type. But, its antioxidant activity results and potentially more modified supplement for elderly health during regular exercise in the community are unclear.ObjectiveThis study aimed to evaluate the antioxidant activity and physical capacity from supplementation of sweet-type SF among elderly people performing home walking exercise.MethodsMixing SF juice with honey industrially prepared the SF product. Its effects on oxidative stress status and physical capacity were studied in four groups; a supplement with walking exercise (n = 11, 67.00 ± 4.17 years), control (n = 12, aged 67.50 ± 5.58 years), supplementation (n = 11, aged 69.63 ± 7.14 years), and walking exercise (n = 12, aged 67.91 ± 4.33 years). Twenty grams or two teaspoons of supplement in warm water (150 mL) was the guideline for consumption twice daily for 4 weeks. In contrast, the walking exercise was prescribed with moderate intensity for 30 min, 3 days per week. Before and after the 4-week period, the oxidative stress status; glutathione (GSH), ascorbic acid (Vit C), total antioxidant capacity (TAC), and malondialdehyde (MDA), and 6-minute walking distance (6MWD) were evaluated.ResultsResults after the 4-week period, showed that Vit C and TAC increased and the MDA decreased significantly in the supplementation group, except the GSH and 6MWD results. The GSH and Vit C slightly decreased in the walking exercise group, whereas, its TAC, MDA and 6MWD increased significantly. Finally, The GSH and Vit C did not decrease and MDA slightly decreased in the combined group, but, their TAC and 6MWD increased significantly.ConclusionSupplementation of the SF product during walking exercise possibly controls oxidative stress status and may enhance walking capacity.

Effects of sea buckthorn pomace on growth performance, serum metabolites and antioxidant indexes of growing pigs

Sea buckthorn pomace (SBP), an agro-industrial waste, containing useful nutrition compounds for animal production. This study aimed to evaluate the effect of growth performance and serum metabolisms in growing pig when consumed SBP. A total of 40 crossbred 70-day-old growing pig with initial body weight (IBW; 30 ±1.5 kg) were randomly assigned to 4 groups. The pigs were fed dietary supplementation of SBP (0.0%, 0.5, 1.5%, and 2.0 %) for 30 d. It concluded that the appropriate level of 1.5% SBP supplementation could improve pig growth performance. Serum immune and antioxidant indexes performed best in 1.5% SBP supplementation group. We suggested that the appropriate level of SBP supplementation would be 1.5% for growing pig, which could improve their growth performance, serum immune and antioxidant indexes.

Effect of postpartum calcium supplementation on serum calcium and parathyroid hormone concentrations in multiparous Holstein cows

Although postpartum Ca supplementation strategies are often employed to prevent subclinical hypocalcemia in dairy cows, these strategies have produced a mix of beneficial, neutral, and detrimental results when assessing milk yield and subsequent disease outcomes. Because the mechanisms underlying these differing results are unknown, our objectives were to determine how common postpartum Ca supplementation strategies affect blood Ca concentrations and parathyroid hormone (PTH). We conducted a randomized controlled trial with 74 multiparous dairy cows on a commercial dairy in central New York. Cows were assigned to 1 of 4 supplementation groups immediately after calving: (1) control (CON; no Ca supplementation, n = 15); (2) conventional oral Ca supplementation (BOL-C; 43 g of oral Ca bolus administered immediately after calving and 24 h later, n = 17); (3) delayed oral Ca supplementation (BOL-D; 43 g of oral Ca bolus administered 48 and 72 h after calving, n = 15); or (4) subcutaneous infusion (SQ; 500 mL of 23% Ca borogluconate infused subcutaneously once immediately after calving, n = 15). Blood samples were collected immediately after calving (0 h) and at 8, 16, 24, 32, 40, 48, 56, 64, 72, 80, 88, 96, 120, and 168 h postpartum for a total of 15 blood samples per cow. Cows were excluded if administered Ca, via any route, by farm employees or if they died or were sold within 96 h following parturition, which left 62 cows for analysis. Linear mixed models, accounting for repeated measures, were created to analyze changes in serum total Ca (tCa) and PTH over the first 168 h after parturition and assess differences between supplementation groups. Serum tCa and PTH concentrations were not different at the time of calving among supplementation groups. There was a supplementation group by hour postcalving interaction for mean tCa concentration in which SQ cows had reduced tCa concentrations from 32 to 64 h compared with CON cows, 32 to 96 h compared with BOL-C cows, and 40 to 64 h compared with BOL-D cows. Mean PTH concentration did not differ among supplementation groups across 168 h after enrollment and was 158.1 pmol/L (95% confidence interval [CI] = 148.2 to 168.0) for CON cows, 164.0 pmol/L (95% CI = 154.9 to 173.1) for BOL-C cows, 158.7 pmol/L (95% CI = 149.2 to 168.1) for BOL-D cows, and 153.2 pmol/L (95% CI = 143.6 to 162.8) for SQ cows. Our findings suggest that although serum tCa does not differ between cows that receive conventional or delayed oral Ca bolus supplementation at calving and cows that receive no supplemental Ca, subcutaneous infusion of Ca at calving reduces serum tCa for a substantial period between 32 and 64 h postsupplementation. However, as PTH concentrations did not differ among groups across 168 h postpartum, the mechanism by which tCa is reduced remains unclear.

Pre-sleep protein supplementation does not improve performance, body composition, and recovery in British Army recruits (part 1).

Dietary protein is crucial for optimising physical training adaptations such as muscular strength and mass, which are key aims for athletic populations, including British Army recruits. New recruits fail to meet the recommended protein intake during basic training (BT), with negligible amounts consumed in the evening. This study assessed the influence of a daily bolus of protein prior to sleep on performance adaptations, body composition and recovery in British Army recruits. 99 men and 23 women [mean ± standard deviation (SD): age: 21.3 ± 3.5 years, height: 174.8 ± 8.4 cm, body mass 75.4 ± 12.2 kg] were randomised into a dietary control (CON), carbohydrate placebo (PLA), moderate (20 g) protein (MOD) or high (60 g) protein (HIGH) supplementation group. Supplements were isocaloric and were consumed on weekday evenings between 2000 and 2100 for 12 weeks during BT. Performance tests (mid-thigh pull, medicine ball throw, 2 km run time, maximal push-up, and maximal vertical jump) and body composition were assessed at the start and end of BT. Dietary intake, energy expenditure, salivary hormones, urinary nitrogen balance, perceived muscle soreness, rating of perceived exertion, mood, and fatigue were assessed at the start, middle and end of BT. Protein supplementation increased protein intake in HIGH (2.16 ± 0.50 g⸱kg-1⸱day-1) and MOD (1.71 ± 0.48 g⸱kg-1⸱day-1) compared to CON (1.17 ± 0.24 g⸱kg-1⸱day-1) and PLA (1.31 ± 0.29 g⸱kg-1⸱day-1; p < 0.001). Despite this, there was no impact of supplementation on mid-thigh pull performance (CON = 7 ± 19%, PLA = 7 ± 19%, MOD = 0 ± 16%, and HIGH = 4 ± 14%; p = 0.554) or any other performance measures (p > 0.05). Fat-free mass changes were also similar between groups (CON = 4 ± 3%, PLA = 4 ± 4%, MOD = 3 ± 3%, HIGH = 5 ± 4%, p = 0.959). There was no impact of protein supplementation on any other body composition or recovery measure. We conclude no benefits of pre-bed protein supplementation to improve performance, body composition and recovery during BT. It is possible the training stimulus was great enough, limiting the impact of protein supplementation. However, the high degree of inter-participant variability suggests an individualised use of protein supplementation should be explored, particularly in those who consume sub-optimal (<1.6 g⸱kg-1⸱day-1) habitual amounts of protein. Clinical trial registration: The study was registered with ClinicalTrials.gov, U.S. national institutes (identifier: NCT05998590).

Assessing the Efficacy of a Modified Triple Drug Regimen Supplemented with Mastic Gum in the Eradication of Helicobacter pylori Infection

Abstract Introduction/Objective Helicobacter pylori (H. pylori) is a bacterium that infects the stomach and small intestine. It is known to be the main cause of gastritis and peptic ulcers. The infection is common worldwide, with a prevalence rate of 50% in many countries. Eradication of H. pylori infection is crucial, as failure to do so can lead to serious complications such as gastric cancer. Treatment for H. pylori infection involves a combination of antibiotics, proton pump inhibitors (PPIs), and bismuth compounds. However, due to the emergence of antibiotic resistance, there is a need for alternative treatments. Methods/Case Report This study had been a randomized controlled trial involving 180 patients with H. pylori infection. The patients had been divided into two groups: Group A received the standard triple-drug regimen (clarithromycin, amoxicillin, and omeprazole), while Group B received the triple-drug regimen along with mastic gum. The treatment duration was 14 days for both groups. Baseline demographics and clinical characteristics had been collected for all patients. The presence of H. pylori infection had been confirmed by a urea breath test and fecal antigen test. Results (if a Case Study enter NA) This study has investigated the effects of mastic gum on H. pylori infection. In a randomized controlled trial of 180 H. pylori-positive patients, mastic gum was found to be effective in eradicating the bacteria in 83 of 90 patients (92.2%) who received the supplementation Group B received the triple-drug regimen along with mastic gum, compared to only 57 of 90 patients (63.3%) in the group A (p &amp;lt; 0.001). Thus, a randomized controlled trial of 90 patients with H. pylori infection found that combination therapy of mastic gum and a triple-drug regimen resulted in a significantly higher eradication rate (92.2%) compared to a triple-drug regimen only (63.3%). Conclusion The current study investigated the adding mastic gum to the standard triple-drug regimen can improve the eradication rate of H. pylori infection. This could potentially offer an alternative treatment option for patients with H. pylori infection, especially those with antibiotic resistance. Applying the mastic gum has approved its effectiveness, and it could reduce the reliance on antibiotics and minimize the risk of resistance development.

Impact of Iron Supplementation in Anemic Voluntary First-Time Blood Donors-Results of a Pilot Trial in Ghana

Introduction : Blood transfusion is a major developmental challenge in sub-Saharan Africa due to chronic inadequacy and shortage of major blood products. In Ghana, deferral of potential blood donors has been identified as a significant challenge. Anemia, accounts for nearly half of ineligible blood donors. The estimated prevalence of anemia is 42.4% in women of reproductive age and 18.8% among peri-urban men ( Spring and Ghana Health service 2016). Thus, a high prevalence of anemia accounting for nearly half of voluntary blood donor deferrals, may contribute to the country's poor availability of safe blood for transfusion. No prior investigation had been carried out in Ghana on whether potential blood donors, deferred due to anemia, would consider donating blood after receiving counselling and appropriate treatment. This study tested the hypothesis that low-dose iron supplementation will increase hemoglobin levels sufficiently among anemic individuals to make them eligible to donate blood. Data from this trial informed the design of a larger randomized control type 1 pragmatic effectiveness implementation hybrid trial. Methods:This was a longitudinal two-arm parallel-group trial (participants aged 18 - 60 years). We compared the hemoglobin levels among those with anemia, iron deficiency (ID) or iron deficiency anemia (IDA) who received iron supplementation to donors without ID or IDA (Control group) in a non-inferiority design(NCT04949165). Anemia, IDA and ID were defined and determined using World Health Organization cut-off values (WHO, 2011). Potential blood donors with hemoglobin values less than 10 g/dl were excluded from the study. Participants in the iron supplementation arm were given low-dose iron (65 mg elemental iron) three times weekly for four months while the control arm received the standard nutritional counselling practice. In-person visits occurred at two, four and six months and included blood draws for full blood count, peripheral blood film smear, malaria rapid test and serum ferritin. The primary outcome was hemoglobin level after four months. A structured questionnaire assessed adherence, nutritional counselling and adverse events every two weeks via phone. Results: Two hundred and twenty-three first-time voluntary blood donors consented and passed pre-screening donation requirements (105 in iron supplementation arm vs. 118 in the control arm). The mean ages were similar between the iron supplementation and control groups (19.7±2.5 vs. 20.1±3.1 years). In both groups, there were more females than males (iron: 75.2%; control: 51.7%). At screening, 43.9% (98/223) had anemia while 3.1% (7/223) had ID. Of those who had anemia, 84.7% (83/98) had ferritin at least 15 g/l while 15.3% (15/98) had IDA. Among controls who donated blood at screening with an interim 1 visit, 42.6% (20/47) of females and 20.9% (9/43) of males were anemic. Only 23.4% (11/47) of females but no male was ID after one blood donation. Among participants assigned to iron supplementation who were anemic at screening, 31.7% (20/63) of females and 28.6% (6/21) of males were no longer anemic at interim visit 1. Among iron participants who were ID at screening 53.3% (8/15) of females and no male (0/2) were iron replete at interim visit 1. Only half of the participants receiving iron supplementation self-reported perfect adherence at the first and second interim visits (end of iron supplementation). A small proportion of participants reported side effects of dark stools and abdominal pain. We did not observe bacterial infections or increased malaria incidence. The mean hemoglobin values decreased over time from baseline to month four in the control group (screening: N=118, 13.4±1.3 g/dl; interim visit 2: N=74, 12.3±1.5 g/dl) and increased in the iron supplementation group (screening: N=105, 11.3±0.9 g/dl; interim visit 2: N=56, 11.4±1.3 g/dl). However, the primary comparison, mean hemoglobin difference between the iron supplementation and control arm at four months, did not meet the threshold to reject the inferiority hypothesis. Conclusion: The prevalence of ID and IDA among voluntary first-time blood donors was lower than previously published estimates. Adherence to low-dose iron supplementation three times a week was poor. Hemoglobin levels in the iron supplementation arm were not close enough to those in the control group after four months of iron supplementation to declare non-inferiority.

Management of Postthyroidectomy Hypoparathyroidism and Its Effect on Hypocalcemia-Related Complications: A Meta-Analysis.

The aim of this Meta-analysis is to evaluate the impact of different treatment strategies for early postoperative hypoparathyroidism on hypocalcemia-related complications and long-term hypoparathyroidism. Embase.com, MEDLINE, Web of Science Core Collection, Cochrane Central Register of Controlled Trials, and the top 100 references of Google Scholar were searched to September 20, 2022. Articles reporting on adult patients who underwent total thyroidectomy which specified a treatment strategy for postthyroidectomy hypoparathyroidism were included. Random effect models were applied to obtain pooled proportions and 95% confidence intervals. Primary outcome was the occurrence of major hypocalcemia-related complications. Secondary outcome was long-term hypoparathyroidism. Sixty-six studies comprising 67 treatment protocols and 51,096 patients were included in this Meta-analysis. In 8 protocols (3806 patients), routine calcium and/or active vitamin D medication was given to all patients directly after thyroidectomy. In 49 protocols (44,012 patients), calcium and/or active vitamin D medication was only given to patients with biochemically proven postthyroidectomy hypoparathyroidism. In 10 protocols (3278 patients), calcium and/or active vitamin D supplementation was only initiated in case of clinical symptoms of hypocalcemia. No patient had a major complication due to postoperative hypocalcemia. The pooled proportion of long-term hypoparathyroidism was 2.4% (95% confidence interval, 1.9-3.0). There was no significant difference in the incidence of long-term hypoparathyroidism between the 3 supplementation groups. All treatment strategies for postoperative hypocalcemia prevent major complications of hypocalcemia. The early postoperative treatment protocol for postthyroidectomy hypoparathyroidism does not seem to influence recovery of parathyroid function in the long term.

Exploring the impact of heat stress on oocyte maturation and embryo development in dairy cattle using a culture medium supplemented with vitamins E, C, and coenzyme Q10

Heat stress is a significant factor affecting the fertility of dairy cattle due to the generation of free radicals. In assisted reproductive techniques, the inclusion of protective antioxidants becomes crucial to mitigate potential cellular damage. This study aimed to explore the impact of supplementing vitamins E, C, and coenzyme Q10 into the oocyte culture medium, with the goal of ameliorating the adverse effects of heat stress on oocyte maturation and embryo development in dairy cattle. A group of fifty Holstein dairy cows were synchronized, and their oocytes were harvested using the ovum pick-up method. High-quality oocytes were subjected to in vitro maturation (IVM) and in vitro fertilization (IVF) procedures, utilizing a culture medium containing, no supplements (Group 1), 100 μM of vitamins E (Group 2) and C (Group 3), along with 50 μM of coenzyme Q10 (Group 4). The ensuing zygotes were cultured, and the ensuing embryos were evaluated for blastocyst formation by the seventh day. An analysis of the blastocysts' inner cell mass (ICM) and trophectoderm (TE) cells was also conducted. The findings revealed that the group receiving supplementation of vitamin E and coenzyme Q10 exhibited significantly higher maturation and cleavage rates in comparison to both the control and the vitamin C groups. Furthermore, the count of ICM, TE, and blastocyst cells was notably elevated in the vitamin E supplemented group when compared to the control group. In summary, the effectiveness of vitamin E in enhancing IVM, IVF, and embryo development under conditions of heat stress surpassed that of vitamin C and coenzyme Q10.

Spirulina Supplementation with High-Intensity Interval Training Decreases Adipokines Levels and Cardiovascular Risk Factors in Men with Obesity

Adiposity, a state characterized by excessive accumulation of body fat, is closely linked to metabolic complications and the secretion of specific adipokines. This study explores the potential of exercise and Spirulina supplementation to mitigate these complications and modulate adipokine release associated with obesity. The primary objective of this investigation was to examine the impact of a 12-week regimen of high-intensity training combined with Spirulina supplementation on adipokine concentrations and lipid profiles in male individuals with obesity (N = 44). The participants were randomly distributed into four groups, each consisting of 11 participants: a control group (CG), a supplement group (SG), a training group (TG), and a training plus supplement group (TSG). The intervention comprised a 12-week treatment involving Spirulina supplementation (6 g capsule daily), a 12-week high-intensity interval training (HIIT) protocol with three sessions per week, or a combined approach. Following the interventions, metabolic parameters, anthropometric measurements, cardiorespiratory indices, and circulating adipokines [CRP, Sema3C, TNF-α, IL-6, MCP1, IL-8] were assessed within 48 h of the before and final training session. Statistical analyses revealed significant differences across all measures among the groups (p &lt; 0.05). Notably, post hoc analyses indicated substantial disparities between the CG and the three interventional groups regarding body weight (p &lt; 0.05). The combined training and supplementation approach led to noteworthy reductions in low-density lipoprotein (LDL), total cholesterol (TC), and triglyceride (TGL) levels (all p &lt; 0.0001), coupled with an elevation in high-density lipoprotein–cholesterol (HDL-C) levels (p = 0.0001). Furthermore, adipokine levels significantly declined in the three intervention groups relative to the CG (p &lt; 0.05). The findings from this 12-week study demonstrate that Spirulina supplementation in conjunction with high-intensity interval training reduced adipokine levels, improved body weight and BMI, and enhanced lipid profiles. This investigation underscores the potential of Spirulina supplementation and high-intensity interval training as a synergistic strategy to ameliorate obesity-related complications and enhance overall cardiometabolic well-being in obese males.

Short-term Administration of Naringin Improves Renal Function in Renal Ischemia-reperfusion by Increasing Aquaporin-1 and Aquaporin-2 Levels

Background:: Since renal ischemia-reperfusion (I/R) can lead to a serious health problem, aquaporins have important roles in preventing negative changes in electrolyte-water balance. This study aimed to determine the effect of naringin treatment on renal function and AQP1 and AQP2 levels in the kidney cortex and medulla tissues in experimental renal I/R in rats. Method and Material: The study was carried out on 40 male Wistar-type rats, 8-12 weeks old. Experimental groups were formed as follows: 1) Control, 2) Sham+vehicle, 3) Renal (I/R)+vehicle, 4) Renal I/R+ Naringin (50mg/kg/day) (3 days of administration), and 5) Renal I/R+ Naringin( 100mg/kg/day) (3 days supplementation) group. First, the left kidney was removed by nephrectomy under general anesthesia, and then the right kidney was subjected to 45 minutes of ischemia and then 72 hours of reperfusion. Naringin was given to the experimental animals by an intraperitoneal route at the beginning of the reperfusion, after 24 and 48 hours. At the end of the experiments, first of all, blood samples were taken from the heart in animals under general anesthesia, and then the animals were killed by cervical dislocation, and kidney tissue samples were taken. Osmolarity in plasma and urine and plasma creatinine levels were evaluated. AQP1 and AQP2 levels were analyzed in the kidney cortex and medulla tissues by ELISA and PCR methods. Result:: In kidney tissues, I/R led to a decrease in plasma and urinary osmolality, AQP1 and AQP2 levels in the cortex and medulla, and an increase in urea and creatinine levels (p &lt; 0.001). However, naringin supplementation corrected the deterioration to a certain extent. Conclusion:: The results of the study show that naringin supplementation at different doses, such as 50 or 100 mg/kg, may have protective effects on the deterioration of renal function caused by unilateral nephrectomy and I/R in rats.

Zinc supplementation in preterm infants and growth indicators in a developing country

Background Zinc is one of the micronutrients that is found deficient in preterm infants. To date, no parenteral zinc supplements are available in Indonesia and there is no recommendation established for routine zinc supplementation in preterm infants.&#x0D; Objective To evaluate the impact of zinc supplementation on growth indicators and morbidity in preterm infants.&#x0D; Methods This double-blind, randomized controlled trial included preterm infants aged 28-32 weeks who were assigned to one of two groups: the first group received a 10 mg zinc supplementation, while the second (control) group received a placebo. At discharge or at a maximum of 40 weeks post-menstrual age (PMA, calculated from the first day of the mother's last menstrual period), the following were evaluated : growth indicators (weight, length, and head circumference), serum zinc level, zinc supplementation side effects, and morbidity rate (intraventricular hemorrhage/IVH, necrotizing enterocolitis/NEC, btonchopulmonary dysplasia/BPD). Data were analyzed with independent T-test using SPSS version 22 software.&#x0D; Results Seventy-eight subjects were assigned to the zinc supplementation group and 76 subjects were assigned to the placebo group. Serum zinc level and mean body weight increment were significantly higher in the zinc group compared to the placebo group (P=0.00 and P=0.02, respectively). There were no significant differences between groups in mean body length or head circumference increment, nor in morbidity rate.&#x0D; Conclusion Preterm infants who received zinc supplementation have higher serum zinc level and mean body weight increment compared to the placebo group. No side effects are observed to have been caused by zinc supplementation.&#x0D; &#x0D; &#x0D;
