Health screening and its association with emergency department visits and related costs among home-dwelling older adults

Background The aim of this study was to evaluate the effectiveness of the health screening procedure for home-dwelling older adults in reducing emergency department visits and associated costs. Methods Data were derived from health screenings from 2020 to 2021 for 75-year-old home-dwelling residents of Western Finland. The study compared emergency department visits and associated costs between older adults who participated in the health screening (intervention group) and those who did not (non-intervention group). For each older adult, three non-intervention controls were matched according to age, sex, health screening year and wellbeing service county. Emergency department visits and International Classification of Diseases (ICD)-10 codes from one year before to two years after health screening were analyzed. Results In the non-intervention group, a 19% increase in emergency visit rates was seen (457–564 per 1000 person-years), while the intervention group showed a 67% decrease (165–23). Annual costs for the non-intervention group increased from 148 euros (€) to €183, a mean ratio increase of 1.24 per person-year (range 1.08–1.40). In contrast, the intervention group’s costs decreased from €53 to €8, a mean reduction ratio of 0.15 per person-year (range 0.10–0.71). The intervention group had lower frequency of visits for respiratory and circulatory diseases but higher for digestive and metabolic diseases, unlike the non-intervention group. Conclusions The implementation of the health screening is an effective strategy for reducing both the frequency of emergency department visits and associated costs in home-dwelling older adults in good condition.

The application of interventional methods in control of blood loss during giant upper extremity tumor resection

BackgroundThe purposes of this retrospective study were to determine the efficacy of interventional methods in control of intraoperative blood losses and investigate the perioperative complications.MethodsThe cases of 44 patients in whom a giant upper extremity tumor had been operated between 2008 and 2022 were analyzed retrospectively. Of these, 29 patients were treated with interventional methods (Group A) and 15 were treated without (Group B). Group A was further divided based on the intervention methodss: Group C (combination of balloon occlusion and transarterial embolization [TAE], n = 11) and Group D (single TAE, n = 18). Within Group D, patients were categorized based on the timing of TAE relative to surgery into Group E (TAE on the same day as surgery) and Group F (TAE performed days before surgery). We compared demographic features, blood loss, ICU admission rates, and use of vasopressors during surgery.ResultsWe collected clinical records from 44 patients diagnosed with a giant upper extremity tumor who underwent surgery. Group sizes were as follows: A (29), B (15), C (11), D (18), E (7), and F (11). Tumor volumes in the interventional and non-interventional groups were similar (704.19 ± 812.77 cm³ vs. 1224.53 ± 1414.01 cm³, P = 0.127). Blood plasma transfusion was significantly higher in Group B compared to Group A (425.33 ± 476.20 ml vs. 155.90 ± 269.67 ml, P = 0.021). Although overall blood loss did not significantly differ between Group A and Group B (467.93 ± 302.08 ml vs. 1150 ± 1424.15 ml, P = 0.087), the rate of massive bleeding (defined as blood loss over 1000 ml) was lower in Group A (6.9% vs. 46.47%, P = 0.004). The proportion of minors (patients aged less than 18) in Group C was significantly higher than in Group D (27.7% vs. 0.00%, P = 0.045). The amount of RBC transfusion was also significantly higher in Group C compared to Group D (458.18 ± 292.22 ml vs. 164.44 ± 224.03 ml, P = 0.021). No significant perioperative complications were observed.ConclusionsInterventional techniques have been shown to reduce both blood loss and the necessity for blood transfusions in patients with large upper extremity tumors. Furthermore, no significant perioperative complications have been observed.

The effectiveness of an intervention using LAWE (loveliness and well-being of employees) app to improve the employee’s mental well-being

Background: Organizations are increasingly seeking comprehensive approaches to improve employee mental well-being (EMW). This study aims to evaluate the effectiveness of interventions delivered through the "Loveliness and Well-being of Employees" (LAWE) app, focusing on five key predictors: "Keep Learning," "Connect," "Take Notice," "Be Active," and "Given". Methods: A quasi-experimental intervention was conducted with 110 participants (53 in the intervention group and 57 in the non-intervention group) from the Kerman University of Medical Sciences in Southeastern Iran. Participants were recruited from a census of all employees at four schools. The intervention involved an Android-based app designed to enhance EMW through pre-designed tasks. Six standard tools were used to assess EMW and its predictors. Data analysis was performed using IBM SPSS Statistics 28, employing Independent Samples T-Test, paired-samples t-test, one-way ANOVA, Spearman correlation coefficient and analysis of covariance (ANCOVA). Results: The intervention group showed a significant increase in mean EMW score, from 52.26±8.61 to 60.01±6.95 (P<0.01). Based on ANCOVA analysis, the post-intervention mean score was significantly higher in the intervention group compared to the non-intervention group by 0.219 points (P<0.01). The mean score of all predictors, except "Take Notice" (P=0.17), also significantly improved in the intervention group. Additionally, post-intervention comparison between the two groups revealed significant differences in mean EMW score (P<0.01), as well as in the mean scores for "Keep Learning" (P<0.05), "Given" (P<0.01), and "Connect" (P<0.01). Conclusion: The LAWE app provides a desirable and comprehensive platform for improving the EMW in organizations. It significantly improves most of the key predictors of EMW, making it a valuable resource for organizations aiming to promote employee well-being.

Effect of an educational intervention program on pregnant women’s ability to cope with childbirth pain in Western Kenya

INTRODUCTION Childbirth pain has remained a major challenge to women of child-bearing age over the years. Studies have shown that most women are not aware of the coping strategies to employ during childbirth. Severe childbirth pain can lead to adverse maternal and neonatal outcomes. Therefore, it is imperative to develop safe and innovative methods to cope with childbirth pain. The study aimed to investigate the effects of an educational program on women's ability to cope with childbirth pain in the context of lower and middle-income countries. MATERIALS AND METHODS A Quasi-experimental design was used to assess the impact of an educational intervention built on self-efficacy theory. Pregnant mothers were recruited at antenatal care services and were assigned to either the control group or the intervention group. The intervention group received two sessions of 2 hours each of the intervention between the 32nd– 35th weeks of gestation. Follow-up and evaluation on outcome measures were conducted within 48 hours after delivery. The strength of pain was measured by the visual analogue pain scale and the Mac-Gill pain questionnaire. RESULTS Findings indicate that relative to the control group, the intervention group was significantly more likely to demonstrate lower perceived pain both on the visual analogue scale (P<0.001) and the McGill pain questionnaire (P<0.001). Further analysis revealed that the non-intervention group had increased severe pain [OR=3.099,95% CI (1.080-8.887), P=0.035], unbearable pain [OR=27.930,95% CI (9.354-83.399), P=<0001], while permanent employment reduced unbearable pain [OR=0.038 95% CI (0.003-0.549), P=0.016]. CONCLUSION AND RECOMMENDATIONS The educational intervention program was effective in decreasing pain intensity and severity during childbirth. Training programs should be integrated into the antenatal care program and offered to mothers during the third trimester of pregnancy to enhance women's coping skills during childbirth.

Effectiveness of heat stress interventions among outdoor workers: a protocol paper.

Heavy work in scorching temperatures can cause dehydration and heat stress, which can lead to a number of heat-related diseases. Heavy work in intense heat without rest or hydration is the main cause. The "Water, Rest, Shade" (WRS) intervention program for outdoor workers in hot weather reduces heat stress. This study follows a quasi-experimental design involving 250 outdoor workers from both agriculture and brick kilns. To assess the environmental heat exposure levels, Quest Temp 3 M WBGT Monitor will be used. Tympanic temperature, Heart rate (HR), Sweat rate (SwR), and Urine specific gravity (USG) to assess the physiological responses to heat exposure using standard protocols. Blood samples will be collected to measure serum creatinine and calculate Glomerular filtration rate (GFR), and urine samples to measure pH, leucocytes, proteinuria, and hematuria. Then administer a validated and modified HOTHAPS questionnaire to capture the perception data. After the baseline assessments, Categorize the workers into two groups based on the selection criteria and the participants' willingness. Then provide a week-long WRS intervention to the intervention group (IG). The non-intervention group will collect the same data without any intervention to assess the efficacy of the intervention by comparing both groups and measuring outcome indicators. The study will generate much-needed information to raise awareness of the importance of heat stress prevention for outdoor workers. This study will demonstrate the effectiveness of an intervention, provide much-needed strategies for reducing heat stress, assess both health impacts and implementation quality, and design comprehensive workplace and labor laws aim to minimise risks to millions of unorganised outdoor workers health.

Perioperative intervention of dysphagia rehabilitation team is effective in older adults with gastric cancer: An inverse probability weighting analysis

IntroductionThis study aimed to evaluate the efficacy of perioperative dysphagia rehabilitation in older adult patients diagnosed with gastric cancer who underwent gastrectomy. Materials and methodsThis retrospective study included 149 patients over 80 years who underwent gastrectomies between January 2000 and December 2020. The patients were divided into two groups based on the intervention of the dysphagia rehabilitation team (DRT group: n = 101) and the non-intervention control group (C group: n = 48). Inverse probability weighting (IPW) analysis was used to reduce bias caused by potential confounding. ResultsThe incidence of overall complications was significantly lower in the DRT group (odds ratio [OR]; 0.27[0.08–0.93]), among which the incidence of postoperative pneumonia (OR; 0.07[0.01–0.43]) and aspiration pneumonia (OR; 0.05[0.01–0.44] was significantly reduced. Ten patients developed postoperative pneumonia; seven were in the C group, and three were in DRT group. Sixty percent of these patients had preoperative comorbidities related to the respiratory system. Regarding the time of onset of aspiration pneumonia, two patterns were observed: onset within a short period after surgery and onset after the start of eating. In contrast, five patients underwent preoperative dysphagia rehabilitation in the DRT group. Among them, postoperative aspiration pneumonia was prevented in four patients, and the others were prevented from severe pneumonitis by the intervention of the dysphagia rehabilitation team. DiscussionPerioperative intervention in dysphagia rehabilitation is not only associated with reduced postoperative pneumonia but also creates awareness in the medical staff and promotes careful observation of swallowing in patients, thereby controlling the incidence of postoperative pneumonia. The perioperative intervention of the dysphagia rehabilitation team is useful for older adult patients with gastric cancer.

Omega‐3 Marine Fatty Acid Supplementation to Healthy Subjects Interacts With Moderate Physical Activity to Provide a Cardiovascular Healthier Lipoprotein Subclass Profile

ABSTRACTThis work investigates the impact of marine omega‐3 and physical activity and their interaction on cardiometabolic health as expressed by the serum lipoprotein profile. Using an experimental design that allows for the possibility of interaction, we performed a 6‐week intervention on 44 middle‐aged women living in Western Norway. The women were randomly divided into four groups: one control group with no intervention, a second group performing sessions of moderate intensity three times per week, a third group taking daily supplements of omega‐3 marine fatty acids, and a fourth group combining the interventions for Groups 2 and 3. The difference in the lipoprotein profiles after the intervention from baseline were assessed for statistical significance by comparing groups 2, 3 and 4 with Group 1 using two‐tailed t‐test corrected for multiple testing and selectivity ratios calculated from the discriminatory component in validated partial least squares discriminant models. The results from the univariate and multivariate analyses were qualitatively equivalent: Only the women combining moderate physical activity and omega‐3 supplementation, revealed statistically significant differences in their lipoprotein profile compared to the nonintervention control group. The pattern of change in the lipoprotein profile is associated with improved cardiometabolic health. Use of the design matrix to predict this pattern revealed that the interaction between omega‐3 supplementation and physical activity played a major role in inducing this change. The recognition of the influence of this interaction may be a step towards resolving the long‐lasting debate of the role played by omega‐3 for preventing cardiovascular unhealth.

A Quality Improvement Initiative for Inpatient Advance Care Planning

The Centers for Medicare & Medicaid Services (CMS) implemented advance care planning (ACP) billing codes in 2016 to encourage practitioners to conduct and document ACP conversations, and included ACP as a quality metric in the CMS Bundled Payments for Care Improvement Initiative in 2018. Use of this billing code in the inpatient setting has not been studied. To determine whether a quality improvement intervention to increase inpatient ACP is effective in increasing ACP billing rates or changing hospital treatment plans or patient outcomes. This nationwide cohort study and difference-in-differences analyses compared changes in ACP billing, treatment, and outcomes in Medicare fee-for-service beneficiaries aged 65 years and older who were hospitalized and cared for by 3 different groups: practitioners employed by a national acute care staffing organization who underwent an ACP quality improvement intervention, nonintervention practitioners at the same hospital, and control group practitioners from other hospitals. Using data from the Master Beneficiary Summary File, acute care hospital stays for nonsurgical conditions were linked to Medicare enrollment, claims, and vital status data from 1-year preadmission to 1-year postadmission from 2015 to 2019. The ACP billing rates for each group were assessed for associations with 6 inpatient treatments and 4 outcomes. Data analyses were performed from January 2022 to December 2024. Billed ACP conversations, receipt of intensive care and life support (intensive care unit admission, gastrostomy tube placement, mechanical ventilation, tracheostomy), treatment limitations (newly initiated do-not-resuscitate orders) and outcomes (discharge to hospice, inpatient death, 30-day postadmission death, and 1-year postadmission death). The total study sample included 109 intervention hospitals, 1691 control hospitals, nearly 12 million Medicare fee-for-service beneficiaries aged 65 years and older, and 738 309 practitioners associated with admissions from 2016 to 2018. ACP billing rates increased more for the intervention (1.3% in preintervention to 14.0% in postintervention; P < .001) than for the nonintervention (same hospitals) and control groups (odds ratio [OR], 2.6; 95% CI, 1.7-4.1 intervention vs control). Increased ACP billing rates were significantly associated with decreased rates of inpatient death in the intervention group (OR, 0.95; 95% CI, 0.90-1.00) compared to the nonintervention (OR, 1.10; 95% CI, 1.04-1.17) and control groups (reference). All other associations were nonsignificant. This nationwide cohort study suggests that while the ACP quality initiative increased ACP billing, changes in clinical outcomes were inconsistent with the hypotheses. Further study is needed to address questions regarding confounding by unobserved measures of care quality.

Olfactory dysfunction management following unilateral cranial resection for olfactory neuroblastoma.

Despite advances in techniques for olfactory neuroblastoma (ONB), such as unilateral cranial resection, preserving the patient’s sense of smell remains a challenge. This study aimed to examine the effectiveness of post-operative olfactory training in patients who underwent unilateral resection of ONB. This retrospective cohort study assessed the effect of post-operative olfactory training on olfactory preservation in patients with ONB undergoing unilateral cranial resection. Patients were divided into training intervention (n = 5) and non-intervention (n = 6) groups. Olfactory tests were conducted pre-operatively and at multiple post-operative intervals. Partial olfactory function was preserved in all cases in the training intervention group, whereas only 17% of cases in the non-intervention group maintained partial olfactory function. Significant improvements in olfactory test scores were observed in the training intervention group compared with the non-intervention group. Our findings suggest that post-operative olfactory training could aid in olfactory preservation for patients with ONB after unilateral cranial resection. However, these results should be interpreted with caution, and further research with larger cohorts and extended follow-up periods is needed to confirm these observations.

Exploring the Effect of an Obesity-Prevention Intervention on Various Child Subgroups: A Post Hoc Subgroup Analysis of the Kiel Obesity Prevention Study.

This study investigated potential subgroups of children within the Kiel Obesity Prevention Study (KOPS) for differing treatment effects for the outcome measures of overweight or obesity at 4 years. The KOPS study delivered a multicomponent school intervention to cohorts of children in Kiel but found no overall effect on the weight status outcome. However, KOPS authors suggested there may be subgroup variations in treatment effect. Data were collected as part of the KOPS for samples of 6-year-olds between 1996 and 2001, with 4-year follow-up measurements between 2000 and 2004. The present study conducted a post hoc subgroup analysis of the odds of obesity or overweight at 4-year follow-up compared to normal weight (n = 1646). A generalized linear mixed-effects model, including a treatment-subgroup interaction term, was used to estimate subgroups as a moderator of the treatment effects on the outcomes of obesity or overweight at 4-year follow-up. The findings indicated several subgroup-treatment interaction effects relating to physical activity indicators. TV or PC not being one of a child's top 3 activities at baseline was associated with a significantly decreased odds ratio of obesity at 4 years in the intervention group (OR, 0.04; 95% CI, 0.004 to 0.45) compared to the non-intervention group (OR, 0.96; 95% CI, 0.29 to 3.14), p = 0.02. Weekly activity in a sports club at baseline was associated with a decreased odds ratio of overweight at 4 years in the intervention group (OR, 0.38; 95% CI, 0.16 to 0.85) compared to the non-intervention group (OR, 0.91; 95% CI, 0.70 to 1.17). This was a significant difference (p = 0.04). These findings suggest that children's baseline physical activity may impact treatment effects on the outcomes of overweight and obesity, creating opportunities to increase the effectiveness of interventions on preventing obesity.

Effects of health education intervention on menstrual hygiene knowledge and practices among the adolescent girls of Pokhara Metropolitan, Nepal.

Poor menstrual hygiene practices are one of the major public health problems in Nepal. Due to persistent taboos and socio-cultural constraints, adolescent girls are often unaware of scientific facts, knowledge, and practices related to menstrual hygiene. This paper aims to assess the effects of health education intervention on menstrual hygiene knowledge and practices among adolescent girls in Pokhara Metropolitan, Nepal. A true experimental study was conducted in two government basic schools in Pokhara Metropolitan, Nepal. The study population was adolescent girls who had attended the menarche. Firstly, a pretest with the help of a self-administered questionnaire was done to find out the socio-demographic information, knowledge and practices of menstrual hygiene. Next, health education sessions were conducted among the intervention group. Finally, after one month of intervention, a post-test was conducted among the intervention and non-intervention group. Data analysis was done through descriptive and inferential statistics. The findings showed significant improvement in the knowledge and practice level of adolescent girls on menstrual hygiene after health education intervention. Participants in the intervention group showed a significant increase in knowledge scores from 10.0% to 67.0%, while the non-intervention group remained unchanged at 7.5%. Good menstrual hygiene practices scores in the intervention group increased significantly from 22.5% to 67.0%, whereas the non-intervention group saw a slight rise from 20.0% to 22.5%. Regarding observed practice scores in menstrual hygiene, significant improvement was observed in the intervention group (45.0% to 100.0%) in contrast to the non-intervention group (25.0% to 27.5%). This study highlights the crucial role of school health education interventions in promoting menstrual hygiene among adolescent girls. It emphasizes the importance of comprehensive educational programs tailored to early teenage girls, addressing timing, content, and delivery methods alongside ensuring the availability of Water, Sanitation and Hygiene (WASH) facilities.

Evaluating fentanyl test strips as a harm reduction strategy in rural and urban counties: study protocol for a randomized controlled trial

BackgroundOpioid-related fatalities are a leading cause of death in Ohio and nationally, with an increasing number of overdoses attributable to fentanyl. Rapid fentanyl test strips can identify fentanyl and some fentanyl analogs in urine samples and are increasingly being used to check illicit drugs for fentanyl before they are used. Fentanyl test strips are a promising harm reduction strategy; however, little is known about the real-world acceptability and impact of fentanyl test strip use. This study investigates fentanyl test strip distribution and education as a harm reduction strategy to prevent overdoses among people who use drugs.MethodsThe research team will recruit 2400 individuals ≥ 18 years with self-reported use of illicit drugs or drugs purchased on the street within the past 6 months. Recruitment will occur at opioid overdose education and naloxone distribution programs in 16 urban and 12 rural Ohio counties. Participating sites will be randomized at the county level to the intervention or non-intervention study arm. A brief fentanyl test strip educational intervention and fentanyl test strips will be provided to participants recruited from sites in the intervention arm. These participants will be eligible to receive additional fentanyl test strips for 2 years post-enrollment. Participants recruited from sites in the non-intervention arm will not receive fentanyl test strip education or fentanyl test strips. All participants will be followed for 2 years post-enrollment using biweekly, quarterly, and 6-month surveys. Primary outcomes include (1) identification of perceived barriers and facilitating factors associated with incorporating fentanyl test strip education and distribution into opioid overdose education and naloxone distribution programs; (2) differences in knowledge and self-efficacy regarding how to test drugs for fentanyl and strategies for reducing overdose risk between the intervention and non-intervention groups; and (3) differences in non-fatal and fatal overdose rates between the intervention and non-intervention groups.DiscussionFindings from this cluster randomized controlled trial will contribute valuable information about the feasibility, acceptability, and impact of integrating fentanyl test strip drug checking in rural and urban communities in Ohio and help guide future overdose prevention interventions.Trial registrationClinicalTrials.gov NCT05463341.

Randomized trial of influence of vitamin D on the prevention and improvement of symptomatic COVID-19

We aimed to investigate the preventive effect of vitamin D2 on COVID-19 and the improvement of symptoms after COVID-19 infection. The study recruited 228 health care workers who tested negative PCR or antigen for COVID-19. Subjects were randomly allocated to vitamin D2 or non-intervention at a ratio 1:1. Subjects recorded PCR or antigen tests and the symptoms of COVID-19 twice a week during the follow-up visit. The concentration of serum 25-hydroxyvitamin D (25(OH)D), C-reaction protein (CRP), complement component C1q and inflammatory cytokines were measured. The rates of COVID-19 infection were 50.5% in the vitamin D2 group and 52.4% in the non-intervention group (P = 0.785). There was no difference in the COVID-19 symptoms between the two groups. The mean 25(OH)D level significantly increased from 14.1 to 31.1 ng/mL after administration (P < 0.001). The difference between the two groups was not significant for the concentrations of CRP, C1q and inflammatory cytokines on the thirtieth day of the trial. According to the second level of vitamin D, there was a 14.3% difference in positive infection rates between the vitamin D adequate (> 30 ng/mL) and deficient groups (< 20 ng/mL). Adequate vitamin D had a tendency to prevent COVID-19.Trial registration: ClinicalTrials.gov NCT05673980, dated: 12/2022.

Effects of enriched environments on behavioral development at toddler period of preterm experienced early repeated procedural pain

Objective: To investigate the effects of enriched environments on behavioral development at toddler period of preterm who had experienced early repeated operative pain. Methods: A cross-sectional study was conducted. A total of 80 high-risk preterm children of 2 years of age, who had experienced repeated pain stimuli in the neonatal intensive care unit (NICU), were enrolled as preterm group from the High-risk Children Clinic of Children's Hospital of Nanjing Medical University from October 2016 to March 2021. Furthermore, 39 full-term healthy children, aged 2 years, who were undergoing routine check-ups during the same period, were selected as the full-term group. The preterm group was further divided into preterm intervention group and preterm non-intervention group based on the implementation of enriched environment interventions. Data of neonatal characteristics from 3 groups were collected. Growth and development indicators at the age of 2 years were measured. Neuropsychological development evaluated by Gesell developmental scale. Behavioral development evaluated by child behavior check list. The salivary cortisol levels in response to novelty (baseline, task, end) were collected. The family environment, including maternal parenting pressure, were evaluated through a survey questionnaire. One-way ANOVA and least significant difference (LSD) tests were used to compare physical development, maternal parenting stress, Gesell neuropsychological development, and behavioral problems among the 3 groups. A repeated-ANOVA and LSD tests were employed to compare the patterns of salivary cortisol secretion. Pearson correlation analysis was used to explore the influencing factors related to neuropsychological and behavioral development and cortisol level. Results: There were 44 cases in the preterm intervention group (17 males, gestational age of (31.3±2.8) weeks), and 36 in the preterm non-intervention group (29 males, gestational age of (32.5±2.6) weeks). The full-term group consisted of 39 children (23 males, gestational age of (39.3±2.1) weeks). At 2 years of age, the height, weight, and head circumference of the preterm intervention group and non-intervention group were all lower than those of the full-term group (all P<0.05).The Gesell developmental schedule showed that the preterm non-intervention group scored all lower in gross motor, fine motor, adaptive, language and personal-social domains compared to the full-term group (91±7 vs. 97±6, 88±9 vs. 94±6, 89±8 vs. 99±8, 84±10 vs. 100±15, 89±7 vs. 95±6), with statistical significance (all P<0.01). The preterm intervention group scored all higher than the preterm non-intervention group in gross motor, fine motor, adaptive and language domains (all P<0.05), with no significant difference compared to the full-term group (all P>0.05). The number of needle painful procedures during hospitalization in NICU of the non-intervention group was negatively correlated to the adaptive development quotient (r=-0.48, P<0.05). Furthermore, the preterm non-intervention group exhibited higher scores in social withdrawal, depression, somatic complaints, aggression, and destructive behaviors compare to the full-term group and preterm intervention group (F=8.07, 5.67, 7.72, 7.90, 7.06; all P<0.05); while the preterm intervention group showed no significant difference compared to full-term group (all P>0.05). Behavioral problems (social withdrawal and depression) in the preterm non-intervention group were positively correlated with maternal parenting stress (r=0.66, 0.50; both P<0.05). In response to novel visual stimuli and cognitive challenges, the preterm non-intervention group had significantly higher salivary cortisol levels compared to the full-term group (P=0.006), which were negatively correlated with the frequency of early painful procedures (r=-0.83, -0.80; both P<0.01). There was no significant difference in cortisol secretion pattern between the intervention group and the full-term group (P=0.772). Conclusion: Enriched environmental interventions can improve neuropsychological development, decrease behavioral problems, and down-regulate consistent high cortisol response to task in preterm infants who have experienced repeated procedural pain in the NICU by the age of 2 years.

Three-dimensional microscope skill acquisition: A randomised controlled study comparing two-dimensional laboratory microscope training, video gaming and virtual reality gaming

IntroductionFine microsurgical motor skill acquisition can be challenging. With increasing technological innovation the method of microsurgical skills acquisition may change. Studies show that laboratory-based microsurgical training programs on a 2D microscope significantly improves novice’s microsurgical skill acquisition. However, are these skills transferable to a 3D microscope or is gaming agility more important? We present a randomised control trial of three interventions, namely laboratory tabletop microscope training (LM), high-fidelity video gaming (Sony PlayStation 4 console) (VG) and high-fidelity virtual reality gaming (Sony PlayStation VR console) (VR) versus a control group. MethodsForty novice medical students were block randomised to four groups: control (no intervention) n=10, LM n=10, VG n=10 and VR n=10. Participants performed chicken femoral artery anastomosis using the Aesculap Aeos® 3D microscope platform at baseline and again after intervention. Performance was evaluated using a modified structured assessment of microsurgery skills (mSAMS) score, time taken to complete anastomosis and time for suture placement by two blinded independent assessors. ResultNo statistically significant difference was noted between the groups at baseline. There was a statistically significant improvement in the LM arm between baseline and post-training for mSAMS score and time for suture placement. In the VG, VR and control groups no statistically significant difference was observed. ConclusionOur study demonstrates that during early microsurgical training, an intense laboratory-based microsurgical training program significantly improves novice’s anastomotic performance on a 2D microscope, and these skills are transferable when a 3D anastomosis is carried out. However, focussed gaming had no significant effect, and the results were akin to the non-intervention group.

Feasibility, Safety, and Effects of an Aerobic Training Program with Blood Flow Restriction on Functional Capacity, and Symptomatology in Women with Fibromyalgia: A Pilot Study.

Evidence suggests that aerobic training with blood flow restriction is beneficial for treating fibromyalgia. This study evaluated the feasibility, safety, and effects of an aerobic training program with blood flow restriction for women with fibromyalgia. Thirty-seven women with fibromyalgia were included, and thirteen with an average age of 59 ± 3, a BMI of 26 ± 3, and who were polymedicated started the intervention period. The intervention group performed aerobic exercise with blood flow restriction using occlusive bands placed in the upper part of the rectus femoris, with a total duration of 14 min of restriction divided into two periods of 7 min with a rest period of 3 min and a total session duration of 17 min. Pressure intensity was measured using the visual pain scale (VAS), scoring 7 out of 10 (n = 7). The non-intervention group performed aerobic exercise without restriction of blood flow for the same periods, rest periods, and total duration of the session (n = 6). The intervention included 2 weekly sessions with 72 h between aerobic walking for 9 weeks. Walking was measured individually using the rating of perceived exertion scale (RPE) with an intensity between 6 and 7 out of 10. Visual and verbal support for the VAS and RPE scale was always provided throughout the sessions supervised by the investigator. Functional capacity was assessed using tests (six-minute walk test, incremental shuttle walk test, knee extension and handgrip test by dynamometer, 30 s chair stand test, and timed up-and-go test). Symptomatology was assessed using questionnaires (Widespread Pain Index, Symptom Severity Score, Fibromyalgia Impact Questionnaire, and Multidimensional Fatigue Inventory), and blood samples were collected. There were no adverse effects, and only one participant in the intervention group withdrew. Between-group and intragroup differences showed that the intervention group obtained improvements in the functional tests; CST p = 0.005; 6MWT p = 0.011; Handgrip p = 0.002; TUGT p = 0.002 with reduced impact of the disease according to the questionnaires; FIQ Stiffness p = 0.027 compared with the nonintervention group. Biochemical results remained within normal ranges in both groups. Blood flow-restricted aerobic training may be feasible, safe, and more effective than unrestricted aerobic training as a physical exercise prescription tool to improve cardiorespiratory fitness, strength, balance, and stiffness in women with fibromyalgia.

"CARBGAME" (CARd & Board GAmes in Medical Education) as an innovative gamification tool for learning clinical enzymology in biochemistry for first year medical students.

Gamification is emerging as an active learning innovation in medical education to enhance student engagement and promote life-long learning in a unique and collaborative environment. Clinical enzymology in biochemistry is one of the core topics in the medical curriculum. However, students face challenges in comprehension and retention of information. Hence, CARd & Board GAmes in Medical Education (CARBGAME)was introduced and evaluated for its effectiveness in enhancing learning, application, and retention of knowledge in clinical enzymology via gamification context. This mixed-method study involved 150 first-year undergraduate medical students. Before the game, students completed a pre-test in clinical enzymology. Later they were divided into 25 small groups to compete in the board game designed for enzymology in biochemistry. The students took turns throwing the dice and answering the questions on the game board to continue moving forward. The first team to reach 100 and solve the case-based question was deemed the winner. Following the board game, the students took up the post-test to compare the educational impact of the innovation. Also, the subsequent internal assessment scores were compared with previous batch who were not implemented with this intervention. Then students evaluated the effectiveness of CARBGAME-Clinical Enzymology using a 32-item questionnaire on 5-point Likert scale. The feedback obtained on a 10-point rating scale and for qualitative analysis, students' and faculty perceptions were recorded in small groups. CARBGAME received overwhelmingly positive feedback from both students and faculty. It was perceived well by students for being fun, relevant, consistent, motivating, collaborative, and promoting experiential learning. The game's low-stakes approach, effective feedback, and sense of accomplishment were highly appreciated, making it a valuable tool for education. A significant improvement in knowledge was recorded, from a mean score of 8.37 ± 1.126 on a 20-point scoring scale before the game to 16.53 ± 1.219 after with a p-value of 0.0001. The comparison of the internal assessment scores between the intervention and non-intervention group of students also showed a significant improvement among those implemented with CARBGAME (p < 0.0001). The CARBGAME innovation has achieved the intended outcome of promoting active learning and enhanced performance in clinical enzymology. Highly positive responses from faculty and students also indicate the exigent need to introduce innovative components like games into curricula to achieve student engagement and promote a meaningful learning experience.

A Comparative Study of Body Composition and Aerobic Capacity between Water and Land Exercise Walking in Male College Students with Mild Obesity

This study explores the impact of water and land fitness walking on the body composition and aerobic capacity of mildly obese male college students. Employing a randomized controlled trial, 36 mildly obese male college students were divided into a water group, a land group, and a non-intervention control group. Following a 4-week exercise intervention, dual-energy X-ray absorptiometry and power bicycle tests assessed body composition and aerobic capacity. The results revealed that both the water and land groups significantly enhanced relative maximum oxygen uptake and lactate threshold, with the water group showing greater improvement. Additionally, water fitness walking significantly reduced body composition indicators including body weight, BMI, waist circumference, waist-to-hip ratio, and thigh circumference. However, there were no significant changes in height, chest circumference, muscle mass, and bone density. The research indicates that water fitness walking uniquely enhances aerobic exercise capacity and body composition, offering a scientific foundation for college students to select effective weight loss exercise methods.

Effect of Mediterranean diet or mindfulness-based stress reduction during pregnancy on placental volume and perfusion: A subanalysis of the IMPACT BCN randomized clinical trial.

The IMPACT BCN trial-a parallel-group randomized clinical trial where 1221 pregnant women at high risk for small-for-gestational age (SGA) newborns were randomly allocated at 19- to 23-week gestation into three groups: Mediterranean diet, Mindfulness-based Stress reduction or non-intervention-has demonstrated a positive effect of Mediterranean diet and Stress reduction in the prevention of SGA. However, the mechanism of action of these interventions remains still unclear. The aim of this study is to investigate the effect of Mediterranean diet and Stress reduction on placental volume and perfusion. Participants in the Mediterranean diet group received monthly individual and group educational sessions, and free provision of extra-virgin olive oil and walnuts. Women in the Stress reduction group underwent an 8-week Stress reduction program adapted for pregnancy, consisting of weekly 2.5-h and one full-day sessions. Non-intervention group was based on usual care. Placental volume and perfusion were assessed in a subgroup of randomly selected women (n = 165) using magnetic resonance (MR) at 36-week gestation. Small placental volume was defined as MR estimated volume <10th centile. Perfusion was assessed by intravoxel incoherent motion. While mean MR placental volume was similar among the study groups, both interventions were associated with a lower prevalence of small placental volume (3.9% Mediterranean diet and 5% stress reduction vs. 17% non-intervention; p = 0.03 and p = 0.04, respectively). Logistic regression showed that small placental volume was significantly associated with higher risk of SGA in both study groups (OR 7.48 [1.99-28.09] in Mediterranean diet and 20.44 [5.13-81.4] in Stress reduction). Mediation analysis showed that the effect of Mediterranean diet on SGA can be decomposed by a direct effect and an indirect effect (56.6%) mediated by a small placental volume. Similarly, the effect of Stress reduction on SGA is partially mediated (45.3%) by a small placental volume. Results on placental intravoxel incoherent motion perfusion fraction and diffusion coefficient were similar among the study groups. Structured interventions during pregnancy based on Mediterranean diet or Stress reduction are associated with a lower proportion of small placentas, which is consistent with the previously observed beneficial effects of these interventions on fetal growth.

Protocolized Foot Exercises Help in Improvement of Diabetic Foot Ulcers and Quality of Life When Added to Standard Therapy-A Randomized Clinical Trial.

Diabetic foot disease is the major cause of nontraumatic limb amputations worldwide causing a high socioeconomic and psychological toll and a huge burden to the healthcare system. Currently, standard treatment of diabetic foot ulcer is through multidisciplinary therapy. Foot exercises have been shown to improve healing in diabetic ulcers although evidence is limited and applicability is non-uniform. Our study aimed to generate more evidence regarding the benefit of addition of protocolized foot exercises so that it can be instituted as a standard of care. It was an open label Randomized controlled trial with seventy-two patients and study duration of one and half years Patients with diabetic foot ulcers were randomized into two groups. Both groups received standard therapy for diabetic foot ulcer. The intervention group in addition received three months of protocolized foot exercises. At the end of three months ulcer healing and quality of life were m compared among both the groups. Regular exercises for three months caused significant reduction in ulcer area compared to the non-intervention group [100% versus 45.22%, 95% CI =36.30(16.04-56.56), P-value = 0.001]. Quality of life analyzed by SF-36 score showed significant improvement in components like physical function [69.4 ± 8.9 versus 63.7 ± 11.0, 95% CI = 5.73 (0.97-10.48), P-value = 0.01], emotional well-being [65.2 ± 7.6 versus 60.8 ± 7.9, 95% CI = 4.44 (0.79-8.10), P-value = 0.01], and pain components [55.4 ± 18.5 versus 47.5 ± 14.5, 95% CI = 7.99 (0.16-15.81), P-value = 0.04) at 3 months although change in social functioning, physical health limitation, health change, energy and general health improvement were not significant. Addition of protocolized foot exercises are beneficial for patients of diabetic foot ulcers in terms of ulcer healing as well as improvement of quality of life provided compliance to exercises can be ensured.
