Radiologic and histopathologic effects of favipiravir and hydroxychloroquine on fracture healing in rats

Fracture healing is a process in which many factors interact. In addition to many treatments, physical and biological therapy methods that affect different steps of this process, there are many biological and chemical agents that cause fracture union delay. Although the number of studies on fracture healing is increasing day by day, the mechanism of fracture healing, which is not fully understood, still attracts the attention of all researchers. In this study, we aimed to investigate the effects of favipiravir and hydroxychloroquine used in the treatment of COVID-19. In this study, 48 male Wistar rats weighing 300 ± 50 g were used. Each group was divided into eight subgroups of six rats each to be sacrificed at the 2nd and 4th weeks and evaluated radiologically and histologically. Favipiravir (group 1), hydroxychloroquine (group 2), favipiravir + hydroxychloroquine (group 3), and random control (group 4) were used. A statistically significant difference was observed between the 15th day histological scoring averages of the groups (p < 0.05). Although there was no statistically significant difference between the 15th day radiological score distributions of the groups (p > 0.05), we obtained different results in terms of complete bone union distributions and radiological images of the fracture line. Although favipiravir has a negative effect on fracture union in the early period, favipiravir may have a positive effect on fracture union in the late period. We did not find any effect of hydroxychloroquine on fracture union.

Acupuncture at five Zang-shu and Ge-shu for bipolar depression: study protocol for a randomized controlled pilot trial

Background: Bipolar disorder is a very common, often misdiagnosed mental disorder strongly associated with comorbidity, disability, and premature mortality. Bipolar depression (i.e., depressive episode in bipolar disorder) is poorly responsive to available treatments. Acupuncture at five Zang-shu and Ge-shu, a prescription from Dr. Leting Wang, is a popular therapy for depression in China. Its effectiveness and safety for bipolar depression is yet to be verified by clinical study. Methods/design: The study is a single-center, prospective, randomized controlled trial involving 72 patients diagnosed with bipolar depression. Participants will be randomized either to the study group or the control group in a 1:1 ratio. All participants will receive mood stabilizer therapy. In addition, the study group will receive acupuncture therapy at five Zang-shu and Ge-shu, three times per week. The control group will orally take the antidepressant bupropion. Observation and intervention will last for 8 consecutive weeks. Outcome measurements include Hamilton Depression Rating Scale-17 (HAMD-17), Hamilton Anxiety Rating Scale (HAMA), Clinical Global Impression Scale (CGI), Young Manic Rating Scale (YMRS), Treatment Emergent Symptom Scale (TESS), serum levels of anti-inflammatory cytokines (IL-4, IL-10, TGF-β), pro-inflammatory cytokines (IL-1β, IL-6, TNF-α), brain-derived neurotrophic factor (BDNF) and C-Reactive Protein (CRP). Assessments will be conducted at baseline, 1st, 2nd, 4th and 8th week after randomization. Safety assessments will be performed throughout the study. Discussion: The results of this study are expected to verify the effectiveness and safety of acupuncture at five Zang-shu and Ge-shu for bipolar depression, and explore its therapeutic mechanisms from the point of anti- inflammation.

Innovative approaches: Exploring nano-biochar technology’s impact on soil properties, alachlor retention, and microbial populations

Pesticide contamination and soil degradation stand as critical challenges in the agricultural ecosystem. This study delves into the impact of nano-biochar (NBC) on soil properties, alachlor retention, and microbial populations, exploring concentrations of 1 %, 3 %, and 5 % w w−1 in both planted and unplanted alachlor-contaminated soil. A six-week black bean-pot experiment was conducted in planted soil. The NBC, distinguished by its substantial carbon content and remarkable surface area, pore volume, and diameter, resulted in significant enhancements in soil pH, moisture content (MC), and soil organic carbon (SOC). Over the 6-week period, NBC3% and NBC1 % consistently increased SOC content, while NBC5% displayed a declining trend after the 4th week. The application of NBC led to a remarkable acceleration in alachlor reduction, achieving efficiencies exceeding 77 % in unplanted soils and reaching an impressive 97.3 % in planted soils. The reduction dynamics, modeled by a first-order equation, revealed notably shorter half-lives of alachlor in NBC-treated soils compared to controls. Abundance in total plate count (TPC), phosphate-solubilizing bacteria (PSB), and nitrogen-fixing bacteria (NFB) increased with NBC1 % and NBC3 %, although NBC5 % showed a decline after the 2nd week. The findings suggest that NBC1 % and NBC3 % offer optimal outcomes for desired soil improvements, enhanced microbial activity, and effective soil pesticide removal.

Treatment Related Acute Toxicities Between Treatment with 3D-CRT and IMRT in Localised Prostate Cancer.

To compare the acute toxicities of two radiation treatment techniques, intensity modulated radiation therapy (IMRT), and 3-dimensional conformal radiation therapy (3D-CRT) in localised prostate adenocarcinoma. Descriptive study. Place and Duration of the Study:Department of Oncology, Dr. Ziauddin Hospital, Karachi, Pakistan, from July 2016 to June 2022. Patients with localised prostate adenocarcinoma who underwent treatment using two different advanced radiotherapy techniques i.e., IMRT and 3D-CRT were recruited during the study period. They were followed up for six months for acute gastrointestinal (GI) and genitourinary (GU) adverse events (acute toxicities) related to both treatment modalities according to Modified radiation therapy oncology group (RTOG) criteria. The acute toxicities were assessed at the 2nd, 4th, and 6th week during treatment and at the 3rd and 6th month after treatment. There were 78 patients, with 39 patients in each group. The mean age was 68 ± 10 years in the 3D-CRT and 68 ± 07 years in the IMRT group. Patients in the IMRT group exhibited markedly lower treatment-related acute GI and GU effects at the end of 4th and 6th weeks for anorectal pain (p = 0.04) and (p = 0.01) and burning micturition (p = 0.003) and (p = 0.01), respectively. Furthermore, at 3 months anorectal pain (p = 0.02), loose stools (p = 0.005), and burning micturition (p = 0.01) were present and at 6 months anorectal pain was (p = 0.01) still present. Radiation therapy modalities 3D-CRT and IMRT both showed acceptable toxicity profile in the management of localised prostate cancer, while IMRT group exhibited significantly lower treatment-related acute GI and GU effects. 3D-CRT (3-Dimensional Conformal Radiation Therapy), IMRT (Intensity-Modulated Radiation Therapy), Radiation toxicity.

Repair of Sciatic Nerve Defect in Rats With Acellular Nerve Allograft Carrying Vascular Endothelial Cells.

Acellular nerve allografts (ANAs) were developed to replace the autologous nerve grafts (ANGs) to fill the peripheral nerve defects. Poor vascularization relative to ANGs has been a limitation of application of ANAs. A total of 60 female Sprague-Dawley rats were assigned 3 groups. The rats in A group received ANGs, the rats in B group received ANAs, and the rats in C group were transplanted with ANA carrying endothelial cells (ANA + ECs). In the 1st, 2nd, 4th, and 12th postoperative weeks, 5 rats were selected from each group for evaluating sciatic function index (SFI), electrophysiology, maximum tetanic force recovery rate, tibialis anterior muscle weights recovery rate, and microvessel density. In the 12th postoperative week, the nerves were harvested and stained with toluidine blue and observed under an electron microscope to compare nerve fibers, myelin width, and G-ratio. All the rats survived. In the first and second postoperative weeks, more microvessels were found in the ANA + EC group. In the 12th postoperative week, the nerve fibers were more numerous, and G-ratio was smaller in the C group compared with the B group. The compound muscle action potential and maximum tetanic force recovery rate in the tibialis anterior muscle in the C group were better than those in the B group in the 12th postoperative week. The A group showed better performances in electrophysiology, maximum tetanic force, muscle wet weight, and nerve regeneration. ANA + ECs can promote early angiogenesis, promoting nerve regeneration and neurological function recovery.

Effect of sowing schedule and integrated nutrient management on productivity, profitability and soil health in rainfed baby corn (Zea mays)–horse gram (Macrotyloma uniflorum) cropping sequence

A field experiment was conducted during the rainy (kharif) seasons of 2012 and 2013 at Ambikapur, Chhattisgarh, to work out the effect of sowing schedule and integrated nutrient-management systems on the pro ductivity and profitability of baby corn (Zea mays L.)–horse gram [Macrotyloma uniflorum (L.) Verdc.] cropping sys tem. The experiment was laid out in a split-plot design with 4 treatments of sowing schedule (1st week of July, 2nd week of July and 3rd week of July and 4th week of July) in main plots and 4 levels of fertility (Recommended dose of fertilizer (RDF), 125% of RDF, RDF + 5 t FYM, 125% of RDF + 5 t FYM) with 3 replications. The horse gram was taken as utera crop sown just before harvesting of baby corn of each sowing schedule by using common starter dose (20-50-20 kg N-P-K/ha). Baby cob, baby corn, green fodder of baby corn plants, horse gram yield and economics were higher in sowing of first schedule (1st week of July) which showed parity with second (2nd week of July) and third (3rd week of July) sowing schedule but significantly superior to the fourth sowing schedule, i.e. 4th week of July. Further, application of 125% RDF + 5 t FYM significantly increased the baby cob, baby corn, green fodder, horse gram yield over 100% RDF and125% RDF, but was at par with that obtained with 100% RDF + 5 t FYM. Combined effect of sowing of the first schedule of baby corn and horse gram and application of 125% RDF + 5 t FYM resulted in significantly higher baby corn-equivalent yield in terms of system productivity (2.8 t/ha) which was comparable to sowing of the second schedule with 125% RDF + 5 t FYM (2.7 t/ha), sowing of the third schedule with 125% RDF + 5 t FYM (2.3 t/ha), sowing of the first schedule with 100% RDF + 5 t FYM (2.7 t/ha), sowing of the second schedule with 100% RDF + 5 t FYM (2.5 t/ha) and sowing of the first schedule with 125% RDF (2.5 t/ha). Hence sowing of baby corn on the first schedule (1st week of July) with 125% RDF + 5 t FYM fol lowed by horse gram revealed the maximum system productivity in terms of baby corn-equivalent yield (2.8 t/ha) and net profit ( 173,000/ha). As regards to nutrient management in baby corn and horse gram system, the maxi mum nutrient uptake (205.7 kg N, 35.5 kg P and 222.8 kg K/ha) and soil fertility status after final harvesting of cropping system (256.19 kg N, 9.1 kg P2 O5 and 281.00 kg K2 O/ha) were registered under 125% RDF + 5 t FYM.

NKCC1 in Neonatal Cochlear Support Cells Reloads Ions Necessary for Cochlear Spontaneous Activity.

In the auditory system, the spontaneous activity of cochlear inner hair cells (IHCs) is initiated by the release of ATP from inner supporting cells (ISCs). This ATP release sets off a cascade, activating purinergic autoreceptors, opening of Ca2+-activated Cl- channel TMEM16A, Cl- efflux and osmotic cell shrinkage. Then, the shrunken ISCs efficiently regain their original volume, suggesting the existence of mechanisms for refilling Cland K+, priming them for subsequent activity. This study explores the potential involvement of NKCCs (Na+-K+-Cl- cotransporters) and KCCs (K+-Cl- cotransporters) in ISC spontaneous activity, considering their capability to transport both Cl- and K+ ions across the cell membrane. Employing a combination of immunohistochemistry, pharmacological interventions, and shRNA experiment, we unveiled the pivotal role of NKCC1 in cochlear spontaneous activity. Immunohistochemistry revealed robust NKCC1 expression in ISCs, persisting until the 2nd postnatal week. Intriguingly, we observed a developmental shift in NKCC1 expression from ISCs to synaptophysin-positive efferent terminals at postnatal day 18, hinting at its potential involvement in modulating synaptic transmission during the post-hearing period. Experiments using bumetanide, a well-known NKCC inhibitor, supported the functional significance of NKCC1 in ISC spontaneous activity. Bumetanide significantly reduced the frequency of spontaneous extracellular potentials (sEP) and spontaneous optical changes (sOCs) in ISCs. NKCC1-shRNA experiments conducted in cultured cochlear tissues further supported these findings, demonstrating a substantial decrease in event frequency and area. Taken together, we revealed the role of NKCC1 in shaping the ISC spontaneous activity that govern auditory pathway development.

Tibia properties in broilers raised on their own commercial diets with different growth rates and sex during a 10-week rearing period.

Genetic selection applied to broilers results in fast growth and an increase in meat yield. However, this situation causes welfare problems in broilers. The aim of this study is to determine the weekly changes in the tibia characteristics in broilers raised on their own commercial diets. In the study, 168 (84 female and 84 male) slow-growing (Hubbard-Isa Red JA) and 168 (84 female and 84 male) fast-growing (Ross-308) day-old broiler chicks were used. Six broilers from each genotype and sex group were weighed weekly and slaughtered to determine the tibia properties during the 10-week fattening period. Fast-growing broilers had higher tibia weight and longer length, diaphysis diameter and medullary canal diameter than those of slow-growing broilers at the same age. In fast-growing genotypes, the cortical index was low only in the 2nd week, and Robusticity and Seedor indices were observed to be better throughout the whole fattening. The ash content of the total tibia in the fast-growing broilers was higher in all of the examined weeks except the 4th week and the 9th week of fattening than that in the slow-growing broilers. Although the amount of ash per unit body weight in the 1st week of fattening was higher in fast-growing broilers, this situation reversed after the 4th week. The level of all minerals examined in total tibia weight is high in fast-growing broilers, and they differed according to the fattening period. When comparing tibia characteristics of two different genotypes fed their own commercial diets, the tibia structure was found to be stronger in fast-growing broilers compared to other genotypes at the same age, but slow-growing broilers were more prominent in terms of body weight. It was observed that the mineral density was higher in male broilers, except in the 1st week.

Effects of electroacupuncture of different intensities and durations on PERK/ATF4/CHOP signaling pathway in liver of non-alcoholic fatty liver disease rats.

To analyze the effects of electroacupuncture (EA) at "Fenglong" (ST40) and "Zusanli" (ST36) of different intensities and durations on rats with non-alcoholic fatty liver disease (NAFLD) based on the protein kinase R-like endoplasmic reticulum kinase (PERK)-activating transcription factor 4 (ATF4)-C/EBP homologous protein (CHOP) signaling pathway, so as to explore its mechanism underlying improvement of NAFLD. SD rats were randomly divided into normal diet group, high-fat model group, sham EA group, strong stimulation EA (SEA) group, and weak stimulation EA (WEA) group, with 15 rats in each group. Each group was further divided into 2, 3, and 4-week subgroups. NAFLD rat model was established by feeding a high-fat diet. After successful modeling, rats in the SEA and WEA groups received EA at bilateral ST40 and ST36 with dense and sparse waves (4 Hz/20 Hz) at current intensities of 4 mA (SEA group) and 2 mA (WEA group), lasting for 20 minutes, once a day, 5 days a week with 2 days of rest. The sham EA group only had the EA apparatus connected without electricity. Different duration subgroups were intervened for 2, 3, and 4 weeks. After the intervention, the contents of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in rats were detected by an automatic biochemical analyzer；liver morphological changes were observed by Oil Red O staining；real-time fluorescence quantitative PCR and Western blot were used to detect the expression of PERK, ATF4, and CHOP mRNAs and proteins in the rat liver tissue. In the high-fat model group, there was a significant accumulation of red lipid droplets in the liver cells, which was reduced significantly in the SEA group at the 4th week. Compared with the normal diet group with the same treatment duration, the contents of serum ALT, AST, and the expression of PERK, ATF4, and CHOP mRNAs and proteins in the liver tissue were elevated (P<0.01) in the high-fat model group . Compared with the high-fat model group with the same treatment duration, the contents of serum ALT, AST, and the expression of PERK, ATF4, CHOP mRNAs and proteins in the liver tissue were decreased (P<0.01, P<0.05) in the SEA and WEA groups. Compared with the sham EA group with the same treatment duration, the contents of serum ALT, AST, and the expression of PERK, ATF4, and CHOP mRNAs were decreased (P<0.01, P<0.05) in the SEA and WEA groups, the expression of PERK, ATF4, and CHOP proteins in the liver tissue was decreased (P<0.01) in the SEA group at the 2nd, 3rd, and 4th week, the expression of PERK and CHOP proteins at the 2nd, 3rd, 4th week and ATF4 protein at 2nd week in the liver tissue were decreased (P<0.01, P<0.05) in the WEA group. Compared with the SEA group with the same treatment duration, the contents of serum ALT, AST, and the expression of PERK, ATF4, and CHOP mRNAs and proteins in the liver tissue were elevated (P<0.05, P<0.01) in the WEA group. Compared with the 2-week time point within the groups, the contents of serum ALT, AST, and the expression of PERK, ATF4, and CHOP mRNAs and PERK proteins in the liver tissue were decreased (P<0.01, P<0.05) in the SEA and WEA groups at 3rd and 4th week, the expression of ATF4 proteins in the liver tissue was decreased (P<0.01) in the SEA group at 3rd and 4th week, and the expression of CHOP proteins in the liver tissue was decreased (P<0.01) in the SEA group at 4th week and in the WEA group at 3rd and 4th week. Compared with the 3-week time point within the groups, the contents of serum ALT, AST, and the expression of PERK, ATF4, and CHOP mRNAs were significantly decreased (P<0.05, P<0.01) in the SEA and WEA groups at 4th week, the expression of PERK and CHOP proteins in the liver tissue was decreased (P<0.01) in the SEA and WEA groups at 4th week, and the expression of ATF4 protein in the liver tissue was decreased (P<0.05) in the SEA group at 4th week. EA at ST40 and ST36 can significantly improve liver function in NAFLD rats, and its mechanism of action may involve inhibiting PERK expression thereby targeting the downstream ATF4/CHOP signaling pathway to suppress endoplasmic reticulum stress, exerting a liver protective effect；the optimal effect was observed with EA intensity of 4 mA for 4 weeks.

Efficacy and Tolerability of a Hyaluronic Acid-Based Extracellular Matrix for Labia Majora Rejuvenation and Augmentation: A Pilot Study.

A new injectable solution containing low-molecular-weight hyaluronic acid (HA) and a specific amino acid mixture was formulated with proper aesthetic performance for the main signs of facial skin photoaging. The present study aimed to investigate its new application for rejuvenating and augmenting labia majora using clinical and biometric assessments. Three sessions of intradermal injections were performed using 3 ml of test extracellular matrix (ECM) for 10 eligible post-menopause female subjects (age 53.6 ± 7.93 years). The effectiveness of the intervention was assessed by an independent physician using before-and-after pictures based on the physician's global assessment score. Objective biophysical skin assessments, including skin hydration, skin erythema, and melanin index, as well as elasticity parameters including firmness (R0), gross elasticity (R2), and net elasticity (R5), were also performed before the first injection and then on the 2nd and 12th weeks after the last session. Patients' satisfaction and all reported or observed adverse events were documented. At week 12, all the subjects reported an aesthetic improvement of 25% or more in rejuvenation and sagging of the labia major area. A statistically significant improvement was also detected in R0 and R5 at week 12 (p-values 0.005 and 0.022, respectively). Patient satisfaction surveys revealed a median score of 8 at both follow-up visits. The results showed a new indication of the tested HA ECM for providing a beneficial, durable, rejuvenating effect on the labia majora with a good safety profile.

The relation between autophagy modulation by intermittent fasting and aquaporin 2 expression in experimentally induced diabetic nephropathy in albino rat

Polyuria is an early sign of diabetic nephropathy (DN) that produces dehydration in diabetic patients. This could be caused by alteration of renal aquaporin 2 (AQP2) expression. This study aimed to describe the relation between autophagy modulation via intermittent fasting (IF) and renal AQP2 expression and polyuria in case of DN. We divided the rats into control, DN and IF groups. After 2 and 4 weeks of diabetes induction, blood glucose (BG), serum creatinine (Scr), urine volume, and 24 hours urine protein (UP) were examined. Diabetic nephropathy histopathological index (DNHI) was calculated to evaluate histopathological changes. Immunohistochemistry and real-time PCR were performed to measure the levels of AQP2 and the autophagy marker; LC3 in kidney tissue. DNHI was correlated to the PCR and immunoexpression of AQP2 and LC3. Intermittent fasting significantly decreased the BG, Scr, urine volume, 24 hours UP, and DNHI as compared diabetes. Diabetes significantly elevated the immunoreactivity and mRNA expression levels of AQP2 and LC3 as compared to the control. However, the IF decreased AQP2 and stimulated autophagy in cyclic fashion. Our data revealed significant positive correlations between AQP2 and LC3 at the level of immunoexpression and mRNA at 2nd weeks. Taken together, these data showed that autophagy stimulation didn’t regulate AQP2 expression in case of diabetic nephropathy, however IF decreased polyuria through improvement of glycemic state.

A Pilot Study to Determine the Effect of Individualized Enteral Nutrition Management Based on Prognostic Nutrition Index on Surgical Patients With Oral Malignancies

This study aimed to assess the effect of individualized enteral nutrition management based on the prognostic nutrition index (PNI) on surgical patients with oral malignancies. This quasi-experimental pilot study consecutively included patients diagnosed with oral malignancies who underwent radical surgery in Ningbo No. 2 Hospital between January 2020 and May 2023. The primary outcome was PNI. A total of 71 patients with oral malignancies were enrolled, and 35 patients received PNI-based individualized enteral nutrition management. The PNI group displayed significantly higher PNI than the routine enteral nutrition support group (1st week postoperatively: 39.86 ± 3.86 vs. 37.29 ± 4.23, p < 0.001. 2nd weeks postoperatively: 44.17 ± 4.36 vs. 40.72 ± 3.40, p < 0.001). The surgical suture removal time and length of hospital stay (both p < 0.001) in the PNI group were significantly shorter than in the routine enteral nutrition support group. At 1 month postoperatively, the PNI group had significantly higher scores of QoL (p = 0.002) than the routine enteral nutrition support group. The individualized enteral nutrition management based on the PNI could improve the nutritional status of postoperative patients with oral malignancy, which could facilitate postoperative rehabilitation and improve overall QoL.

Potential of the domestic biosimile omalizumab in achievement of control in patients with severe asthma: short communication

BACKGROUND: Severe atopic asthma is a medical and social problem due to its prevalence, the tendency to exacerbations, the impact on the quality of life and on the work ability, and high treatment costs. The appearance biosimilar omalizumab among biologicals makes such therapy more accessible to patients. This article presents the results of an open prospective clinical study of the biosimilar omalizumab in patients with the severe atopic asthma.&#x0D; AIM: To evaluate the efficacy and tolerability of the domestically produced biosimilar omalizumab in the real clinical practice.&#x0D; MATERIALS AND METHODS: The study involved 15 adult patients (19–66 years) with a reliable history consistent with moderate to severe atopic asthma who hadn`t have asthma control at the time of inclusion in the study. All patients received the Genolar (omalizumab, Generic JSC, Russia) for 52 weeks at the dose calculated according to the instructions. The efficacy was evaluated taking into account changes in symptom severity, improved asthma control using the Asthma Control Questionnaire (ACQ-5), pulmonary function tests, peak flow measurements, assessment the asthma exacerbations number and the healthcare resources use.&#x0D; RESULTS: According to our study results, all patients demonstrated a decrease in the night and daytime attacks frequency and the shortness of breath severity due to omalizumab, which made it possible to reduce the basic therapy and refuse systemic glucocorticosteroids using in patients who previously received there. After 6 months we obtained an improvement in the asthma symptoms control: ΔACQ-5=-1.87 (p=0.0002) compared to baseline with a trend towards further improvement in indicators and reached ΔACQ-5=-2.18 (p=0.0001) to the 52nd week. We also obtained a statistically significant improvement in pulmonary function (after a year of treatment, the increase in forced expiratory volume in the first second was +19.85% compared to baseline, p=0.0001). No asthma exacerbation was registered during 12 months omalizumab treatment.&#x0D; CONCLUSION: Our study showed that the biosimilar treatment in patients with severe atopic asthma allowed to achieve asthma control, decrease the exacerbations number and reduce the basic therapy volume, including oral-corticosteroid elimination.

Incidence of Pocket Infection after Implantation of Permanent Pacemaker

Objective: The research aimed to enhance clinical awareness and optimise preventive strategies in permanent pacemaker (PPM) implantation&#x0D; Methodology: We followed the patient on 2nd and 4th weeks after implantation of PPM. A total of 500 patients were followed over a 1-year period of time. We defined pocket PPM infection as the presence of local oedema and redness or swelling with and without systemic signs of infection that required antibiotic therapy and/or device removal.&#x0D; Results: The mean age of the patients was 55.4 ± 14.2 years, and 58% were male. The most common indications for PPM implantation were atrioventricular block (42%), sick sinus syndrome (32%), and atrial fibrillation with slow ventricular response (18%). The median follow-up time was 12 months. The overall incidence of PPM infection was 2.4% (12 cases).&#x0D; Conclusion: PPM pocket infection is a rare but serious complication that occurs mainly within the 2 weeks after implantation. Diabetes mellitus, renal failure, and the use of temporary pacing wires are significant risk factors for PPM infection. Prevention strategies and close follow-up are essential to reduce the morbidity and mortality associated with this complication.

Efficacy and safety of pelvic floor magnetic stimulation combined with mirabegron in female patients with refractory overactive bladder: a prospective study.

To observe the efficacy and safety of pelvic floor magnetic stimulation (PFMS) combined with mirabegron in female patients with refractory overactive bladder (OAB) symptoms. A total of 160 female patients with refractory OAB symptoms were prospectively randomized into two groups. Eighty cases in the combination group accepted PFMS and mirabegron therapy and 80 cases as control only accepted mirabegron therapy (The clinical trial registry number: ChiCTR2200070171). The lower urinary tract symptoms, OAB questionnaire (OAB-q) health-related quality of life (HRQol), symptom bother score and OABSS between two groups were compared at the 1st, 2nd and 4th week ends. All of 160 patients were randomly assigned to two groups, of which 80 patients were included in the combination group and 80 in the mirabegron group. The incidences of LUTS, including urgency, frequent urination, and incontinence episodes, in the 2nd week and the 4th week after combination treatment were significantly lower than those in the mirabegron group (p < 0.05). The incidence of drug-related adverse events between two groups was similar, and there was no statistically significant difference (p > 0.05). With respect to secondary variables, the OAB-q HRQol score in the combination group was statistically superior in comparison with that in the mirabegron group between the 2nd week and the 4th week (p < 0.05). This was consistent with the primary outcome. Meanwhile, from the second to fourth week, the OAB-q symptom bother score and OABSS in the combination group were both lower than in the mirabegron group (p < 0.05). Combination therapy of PFMS and mirabegron demonstrated significant improvements over mirabegron monotherapy in reducing refractory OAB symptoms for female patients, and providing a higher quality of life without increasing bothersome adverse effects. https://www.chictr.org.cn/, ChiCTR-INR-22013524.

Comparison of the Efficacies of Vicryl Rapide and Prolene Sutures in Transcolumellar Incision.

&lt;b&gt;&lt;br&gt;Introduction:&lt;/b&gt; Septorhinoplasty aims to enhance nasal function and appearance. This common but complex procedure has demonstrated advancements with both open and endonasal approaches. The selection of sutures can impact patient comfort and scar outcomes, presenting both advantages and disadvantages.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Aim:&lt;/b&gt; This study was conducted to compare the cosmetic outcomes of the use of absorbable polyglactin 910 (PG) (Vicryl Rapide 5/0; Ethicon Inc.) and nonabsorbable polypropylene (PP) (Prolene 5/0; Ethicon Inc.) in open septorhinoplasty in terms of surgical scarring.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Methods:&lt;/b&gt; The sample of this prospective, randomized, single-blind study consisted of 42 patients who underwent open septorhinoplasty. The patients were randomized into the vicryl rapide (n = 16) and prolene (n = 26) suture groups. The groups were comparatively evaluated by two surgeons in terms of surgical scarring, pigmentation, level difference, indentation, and general appearance based on patient photographs taken in the 2nd week, 6th weeks and 12th week post-op.&lt;/br&gt; &lt;b&gt;&lt;br&gt;Results:&lt;/b&gt; The mean age of the vicryl rapide and prolene groups was 26.9 5.7 years and 24.6 3.9 years, respectively. There was no significant difference between the groups in any of the parameters investigated within the scope of the study in postoperative week 2, 6, and 12 (P &gt; 0.05). On the other hand, intragroup analyses revealed that suture scar significantly decreased in the vicryl rapide group in the 6th and 12th weeks compared to the 2nd week (P &lt; 0.05), while no significant difference was observed in the prolene group in the suture scars in week 6 and 12 compared to week 2 (P &gt; 0.05).&lt;/br&gt; &lt;b&gt;&lt;br&gt;Conclusions:&lt;/b&gt; Inverted V trans-columellar incisions sutured with rapidly absorbable suture material resulted in significantly less suture discomfort and did not significantly increase the risk of postoperative infection compared to nonabsorbable suture material. However, there was no significant difference between the two suture materials in terms of scar appearance.&lt;/br&gt.

Effect of active static stretching on glycemia in type 2 diabetes

Background: Type 2 diabetes Mellitus (T2DM) is a chronic disease whose prevalence is increasing worldwide. It is characterized by insulin resistance in insulin-dependent tissues (e.g. skeletal muscle, adipose tissue). Despite new evidence that stretching may aid in glycemic control, this form of physical exercise remains underutilized in the therapy of T2DM. Objective: The objective of this study was to evaluate the effects of active static stretching on the glycemia of individuals with T2DM. Methods: Twenty-nine volunteers participated in the study, divided into 3 randomly assigned groups: 30-second stretching group (GA30) with 10 participants; 45-second stretching group (GA45) with 10 participants; control group (CG) with 9 participants. Results: Analysis of the intervention groups versus the control group showed that the intervention groups GA30 and GA45 had a significant milligrams per deciliter (mg/dl) reduction in glycemia compared to the control group (control Δ-7.9mg/dl, GA30 Δ12.7mg/dl and GA45 Δ18.5mg/dl &gt;0.001) and between intervention groups (GA30 and control Δ 20.5mg/dl, P 0.002), GA45 and control (Δ 26.4mg/dl, P 0.001). There was no difference between the intervention groups. The results suggest that, regardless of the application time, active static stretching reduces glycemia in individuals with T2DM. In an analysis divided into 4 stages (1st and 2nd weeks, 3rd and 4th weeks, 5th and 6th weeks, and 7th and 8th weeks), the results obtained from the glycemic difference before and after each two weeks were as follows: GA30 pre and post (1st ≠ 17.4 mg/dl, 2nd ≠ 5.8 mg/dl, 3rd ≠ 14.5 mg/dl, and 4th ≠ 8.9 mg/dl), GA45 pre and post (1st ≠ 18.1 mg/dl, 2nd ≠ 17.0 mg/dl, 3rd ≠ 19.2 mg/dl, and 4th ≠ 20.0 mg/dl), and CG pre and post (1st ≠ -10.4 mg/dl, 2nd ≠ -3.7 mg/dl, 3rd ≠ -11.4 mg/dl, and 4th ≠ -11.7 mg/dl). Conclusion: This interaction between the two-factor period (Group and Period) did not have a significant effect. Finally, a descriptive analysis of pre- and post-intervention glucose behavior showed the variability of glycemia during the period. Thus, active static stretching significantly reduces acute and chronic glycemia in individuals with T2DM compared to control.

Role of insole material in treatment of plantar fasciitis: A randomized clinical trial

BackgroundIn this randomized clinical trial, we compared the early effects of polyethylene (PE), polyurethane (PU), and Carbon Fiber insoles in the treatment of PF using a set of patient-reported outcomes. MethodsPatients were randomly allocated one of the three prefabricated insoles – Carbon Fiber (n = 14), PU (n = 14), or PE (n = 17) for regular use. Their response was recorded using PROMIS 3a (for pain intensity), PROMIS 4a (for pain interference), FAOS (Foot and Ankle Outcome Score), and VAS for pain at baseline, two, six, and twelve weeks. ResultsThe PROMIS pain intensity scores improved in both the Carbon Fiber and the PE groups starting at the 6th week (p = 0.04) and 2nd week (p = 0.002), respectively. PROMIS pain interference scores also showed positive trends in these two groups (p = 0.02, p = 0.004, respectively). ConclusionPrefabricated Carbon Fiber and PE insoles showed significant pain-reducing effects in patients with PF. Levels of evidenceLevel I, Randomized controlled trial.

Investigation of Differences in the Techniques of Experimental Vitreo-retinal Operations on Laboratory Animals

The continuous development of vitreoretinal surgery makes it possible to provide high-tech care to patients with retinal detachment while minimizing intraand postoperative complications. However, their percentage still remains significantly high. This pushes modern ophthalmological science to new research and search for solutions to existing problems. In this task, laboratory animals, on which the latest advances in medicine have been tested for more than 100 years, help like no one else. Unfortunately, the high cost of experiments often repels and/or pushes them back indefinitely. Given the clinical significance of experimental studies of surgical treatment of retinal detachment, as part of the study of the new hydrogel preparation Vitreolon, an analysis was made of methods for removing the vitreous body and their effect on the result of surgical intervention.Purpose: analysis of differences in vitreous removal techniques in laboratory rabbits.Material and methods. The experiment involved 6 rabbits (12 eyes) with induced retinal detachment. In 6 eyes, vitrectomy was performed using a vitreotome, in the others, using a syringe (21G). Subsequently, tamponade of the vitreal cavity was performed with the new hydrogel preparation “Vitreolon”. Ophthalmological examinations were performed on the 1st day, 1st and 2nd week, 1st and 3rd months after surgery. After that, the eyes were enucleated to conduct a morphological study of macropreparations and histological sections of the eyes.Results. According to the results of ophthalmological and laboratory studies, there was no statistically significant difference between the techniques for removing the vitreous body. One rabbit had hypertension and cataracts, which indicates its individual response to surgery. There were no complications that could lead to early termination of the experiment.

Retrospective Cohort Study Comparing Efficacy and Safety of Pharmacological Intervention and Phototherapy in Moderate to Severe Psoriasis Patients in a Real-World Setting

Abstract Methotrexate (MTX) is one of the first-line systemic treatment options in patients with moderate-to-severe plaque psoriasis and can be combined with narrow band UVB phototherapy (Nb-UVB). However, such a combination is rarely used for optimal duration due to safety and efficacy concerns. The aim of this study was to assess efficacy and safety of methotrexate (MTX) combination with low doses of Nb-UVB versus MTX monotherapy in patients with moderate-to-severe plaque psoriasis in a real-world setting. Retrospective psoriasis patient medical chart review was performed for the period from 2013 till 2019. The combination therapy group (Group 1, n = 74) received MTX 10 mg s/c once a week for four to six weeks and 311 nm UVB phototherapy according to the skin type and protocol of administration — three times a week; undergoing 10–24 procedures in the treatment course. The monotherapy group (Group 2, n = 57) was treated, using MTX as monotherapy 2.5 mg two times a day orally for five days (4–6 treatment courses in total). The combination therapy group achieved decrease of mean PASI at the end of the 2nd week of treatment by 38% vs monotherapy group 21%. Combination of low dose subcutaneous MTX and Nb-UVB therapy provides better treatment outcomes and normalisation of immunochemical parameters than for MTX monotherapy. This combination also showed a favourable tolerability profile.
