Assessing malathion residue impact on poultry health, human safety, and production performance.

Over the past decade, food safety has become a major concern due to the intensive use of pesticides. Pesticide contamination has been observed in poultry products when seeds are coated with pesticides or when stored products are exposed to pesticides in warehouses. In this experiment, the residue levels of malathion transferred from corn grain to the different parts of the chicken product, its transfer factors (TFs) and the human dietary risk for consumers were evaluated. Growth performance and carcass parameters of the chicken samples were also determined after different doses of malathion exposure. Malathion residues from different parts of chicken meat (breast, thigh, wing, liver and skin) were extracted by the QuEChERS method and analyzed by liquid chromatography-mass spectrophotometry (LC-MS/MS). A deterministic approach was used to calculate the acute and chronic risk assessment. Body weight, feed conversion ratio and feed intake decreased with increasing malathion dose. In addition to reduced feed intake, cold carcass and liver weights of the chicks were also decreased. The highest residues were found in the skin of the chicken followed by the breast, thigh, wing and liver. The TFs of malathion varied between 0.00 and 0.05 according to the different doses applied (4 mg/kg, 8 mg/kg, 16 mg/kg, 32 mg/kg). The chronic exposure assessment (HQ) showed that consumers of all ages and genders consumed 0.008-0.604% of the acceptable daily intake (0.3 mg/kg body weight (bw)/day) of malathion from chicken products. The acute intake assessment (aHQ) of consumers ranged from 0.00015 to 0.0135% of the acute reference dose (0.3 mg/kg bw). In conclusion the results suggest that the risk associated with the malathion residues in chicken meat was found to be low but the residue levels in meat should not be ignored.

Comparative analysis of four nutritional scores in predicting adverse outcomes in biopsy-confirmed diabetic kidney Disease.

Malnutrition is associated with adverse outcomes in patients with diabetic kidney disease (DKD). However, it is uncertain which nutritional assessment tools are most effective in predicting the adverse outcomes of DKD. This retrospective study was conducted at a single center and included 367 patients diagnosed with DKD based on biopsy results between August 2009 and December 2018. Four nutritional assessment indices, namely the Prognostic Nutritional Index (PNI), Geriatric Nutritional Risk Index (GNRI), Triglycerides (TG) × Total Cholesterol (TC) × Body Weight (BW) Index (TCBI), and Controlling Nutritional Status (CONUT) score, were selected and calculated. We aimed to assess the association between these nutritional scores and adverse outcomes, including progression to end-stage kidney disease (ESKD), cardiovascular diseases events (CVD), and all-cause mortality. Univariate and multivariate Cox regression analyses, Kaplan-Meier analysis, along with Restricted cubic spline analysis were used to examine the relationship between nutritional scores and adverse outcomes. Furthermore, the area under the curve (AUC) was calculated using time-dependent receiver operating characteristics to determine the predictive value of the four nutritional scores alone and some combinations. Lastly, ordered logistic regression analysis was conducted to explore the correlation between the four nutritional scores and different renal histologic changes. The incidence of ESKD, CVD, and all-cause mortality was significantly higher in patients with DKD who had a lower PNI, lower GNRI, and higher CONUT score. Additionally, The TCBI performed the worst in terms of grading and risk assessment. The PNI offer the highest predictive value for adverse outcomes and a stronger correlation with renal histologic changes compared to other nutritional scores. Patients diagnosed with DKD who have a worse nutritional status are more likely to experience higher rates of adverse outcomes. The PNI might offer more valuable predictive values and a stronger correlation with different renal histologic changes compared to other nutritional scores.

Intake of foods high in saturated fats, vegetarian dietary pattern, and sociodemographic characteristics associated with body weight in Peruvian university students.

Background: The prevalence of obesity continues to increase among university students and the general population. Consumption of a diet high in saturated fats could be one of the risk factors. Objective: The consumption of foods high in saturated fats, the vegetarian diet pattern, and sociodemographic characteristics associated with excess body weight (overweight/obesity) were evaluated in Peruvian university students. Methods: A cross-sectional study was carried out selecting 5,608 Peruvian university students through no probabilistic convenience sampling. The survey was carried out during the months of February and April 2022. The Chi-square test and binary logistic regression analysis were used to evaluate the association between diet (saturated fats intake and dietary pattern) and sociodemographic factors with excess body weight in a cross-sectional analysis. Results: It was observed that students who reported high consumption of foods high in saturated fats (ORB = 1.14) and those who had a non-vegetarian dietary pattern (ORB = 2.76) were found to be more likely to have excess body weight. On the contrary, students who reported adherence to the vegetarian diet pattern for more than 5 years were less likely to be overweight or obese (ORB = 0.84). Being ≥26 years of age (ORB = 3.28), living in urban areas (ORB = 1.68) and coastal areas of the country (ORB = 1.17), and enrolled in the engineering faculty (ORB = 1.19), were significantly associated with excess body weight. Conclusion: The findings of the current study evidenced several factors associated with excess body weight in university students. Therefore, it is necessary to promote and implement healthy lifestyle programs, considering sociodemographic and dietary aspects such as age and dietary intake to control and prevent obesity in university students.

Gut microbiota derived from fecal microbiota transplantation enhances body weight of Mimas squabs.

Objective: Compared to Mimas pigeons, Shiqi pigeons exhibit greater tolerance to coarse feeding because of their abundant gut microbiota. Here, to investigate the potential of utilizing intestinal flora derived from Shiqi pigeons, the intestinal flora and body indices of Mimas squabs were evaluated after fecal microbiota transplantation (FMT) from donors. Methods: A total of 90 one-day-old squabs were randomly divided into the control group (CON), the low-concentration group (LC) and the high-concentration group (HC): gavaged with 200 µL of bacterial solution at concentrations of 0, 0.1 and 0.2 g/15 mL, respectively. Results: The results suggested that FMT improved the body weight of Mimas squabs in the HC and LC groups (p < 0.01), and 0.1 g/15 mL was the optimal dose during FMT. After 16S rRNA sequencing was performed, compared to those in the CON group, the abundance levels of microflora, especially Lactobacillus, Muribaculaceae and Megasphaera (p < 0.05), in the FMT-treated groups were markedly greater. Random forest analysis indicated that the main functions of key microbes involve pathways associated with metabolism, further illustrating their important role in the host body. Conclusion: FMT has been determined to be a viable method for augmenting the weight and intestinal microbiota of squabs, representing a unique avenue for enhancing the economic feasibility of squab breeding.

Efficacy of oral nutritional supplement in cancer patients receiving chemotherapy: a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: The use of oral nutritional supplement (ONS) is one of the modalities employed to manage cancer-associated malnutrition. However, evidence of its efficacy is limited. In 2018, a meta-analysis reported the statistical benefits of increased body weight from ONS. This study aimed to evaluate the efficacy of ONS in cancer patients receiving chemotherapy in more recent trials. METHODS: All randomized controlled trials (RCTs) of adult cancer patients receiving chemotherapy, which compared ONS with standard of care and reported on body weight, nutritional status, or quality of life (QoL), were included. Eligible RCTs were identified from PubMed, OVID, and the references of previous systematic reviews up until February 2023. The risk of bias was assessed using the Revised Cochrane risk-of-bias tool. The outcomes of interest were pooled and analyzed using the mean difference (MD) with a corresponding 95% confidence interval (CI). This study was registered in PROSPERO, number CRD42023400471. RESULTS: Ten RCTs comprising 1,101 patients were included. ONS did not show a significant impact on final body weight (MD -0.07 kg, 95% CI: -0.99 to 0.84, P=0.88). It tended to increase body weight (MD 0.90 kg, 95% CI: -0.48 to 2.28, P=0.20), and this benefit was particularly noticeable in elderly patients, those with low baseline body weight, females, and non-Asian patients. After adjusting for risk of bias, ONS was found to significantly increase body weight (MD 1.32 kg, 95% CI: 0.12 to 2.52, P=0.03), and it also tended to enhance Patient-Generated Subjective Global Assessment (PG-SGA) score of -2.13 (95% CI: -5.07 to 0.82, P=0.16), global domain QoL score of 4.01 (95% CI: 0.08 to 7.94, P=0.05) and fatigue domain QoL score of -7.63 (95% CI: -13.87 to -1.39, P=0.02). CONCLUSIONS: ONS could help to increase body weight in cancer patients receiving chemotherapy. This benefit was especially notable in those at high risk of malnutrition, including elderly patients, those with low baseline body weight, females, and non-Asian patients. It also resulted in improved PG-SGA scores and significantly improved patients' QoL during chemotherapy treatment. Future studies should explore the potential benefit of ONS on oncological outcomes or improvements of chemotherapy-related toxicity.

Effect of Fish-Based Diet on Malnourished Children: A Systematic Review.

Background: Malnutrition in children is mainly caused by the lack of protein and fat intake which harms their ability to grow and survive. Accurate data on the benefits of fish-based foods on the nutritional status of children is limited. The present systematic review aimed to provide an overview of published articles on the nutritional value of fish-based foods for children. Methods: A systematic review was performed during 2000-2021 by searching Science Direct, Cochrane Library, PubMed, ProQuest, and Wiley Online Library databases. The full text of selected articles in English was screened based on the inclusion and exclusion criteria. Included articles were all experimental studies (randomized control trial, quasi-randomized trial) or mixed methods studies involving malnourished children. The study was reported under the preferred reporting items for systematic reviews and meta-analyses guidelines. The risk of bias was assessed using the Cochrane tool. Results: A total of 330,859 articles were screened, out of which eight articles were included in the systematic review. Interventions included fish-based foods and beverages such as wafer bars, Jemawut-tuna cookies, Amizate in chocolate drink, dried fish powder, flaxseed oil supplemented with fish oil capsules, and porridge fortified with fish powder. Primary or secondary outcomes were the determination of zinc level, height growth, erythrocyte n-3 polyunsaturated fatty acid content, safety and acceptability, intestinal integrity, and cognitive development. The results showed that dried fish powder produced the most significant effect on body weight. Conclusion: The consumption of dried fish powder had positive effects on the recovery of malnourished children.

Effect of adjunct Vitamin D treatment in vitamin D deficient pulmonary tuberculosis patients: A randomized, double blind, active controlled clinical trial.

BACKGROUND: Since, Vitamin D [1α,25(OH)2D)] enhances antimicrobial activity of Innate immunity and modulate Adaptive immune responses, simultaneously, so it play a potential role for balanced immune activity against Mycobacterium tuberculosis and restricting tissue injuries within the TB patients.(Chun et al., 2011) 9 We aimed to determine the role of adjunct Vitamin D treatment on the outcome of pulmonary tuberculosis patients and evaluated the effect of Vitamin D administration on Differential Leucocyte Count, Erythrocyte Sedimentation Rate, serum Adenosine deaminase, serum C- reactive protein, Oxygen saturation (SpO2) and Body Weight in Vitamin D deficient pulmonary tuberculosis patients. METHODS: We conducted a prospective, interventional, randomized, double blind, parallel group, active controlled clinical trial. Newly diagnosed Vitamin D deficient pulmonary tuberculosis patients were randomly assigned to intervention group (received standard anti-tubercular treatment with adjunct Vitamin D3) and control group (received standard anti-tubercular treatment without adjunct Vitamin D3). Total four doses [each dose of 2.5 mg (100000 IU)] of Vitamin D3 were given, orally. First dose was given within 7 days of starting anti-tubercular treatment and second, third, fourth dose were given at 2, 4 and 6 weeks respectively. At the time of enrollment, we measured all baseline characteristics. During follow-up, we measured the study variables and monitored adverse events at 2, 4, 6, 8 and 12 weeks. Our safety parameter was serum corrected calcium level to assess the risk of hypercalcemia. RESULTS: Total 130 pulmonary TB patients, 65 patients in each group, were analyzed. Our study results showed that decrease in Neutrophil count was statistically significant with small effect sizes at every time point of measurement and increase in Lymphocyte count was statistically significant with small and moderate effect sizes at 4, 6 and 8 week for intervention group than for control group. Decrease in erythrocyte sedimentation rate was statistically significant with small effect sizes at 6 and 8 week, decrease in serum adenosine deaminase and serum C- reactive protein was statistically significant with moderate effect sizes at 4, 6 and 8 week for intervention group than for control group. Increase in Oxygen saturation was statistically significant at 4 week with small effect size and increase in body weight was statistically significant with small effect sizes for intervention group than for control group. No case of hypercalcemia was reported. CONCLUSION: Our findings suggest a potential role of adjunctive Vitamin D3 to accelerate resolution of inflammatory responses and improvement in clinical outcomes of pulmonary TB patients. TRIAL REGISTRATION: This trial is registered with Clinical Trials Registry - INDIA (http://ctri.nic.in) with CTRI Number - CTRI/2021/11/037914.

EXPRESS: Can weight-adjusted waist circumference index become a single anthropometric predictor of prostate specific antigen concentration? An NHANES analysis (2003-2010).

Recent studies have introduced the weight-adjusted waist circumference index (WWI) as a viable obesity indicator that may better reflect centripetal obesity and its associated risks. In examining the connection between WWI and prostate-specific antigen (PSA), this study leveraged data from the National Health and Nutrition Examination Survey (NHANES) 2003-2010, including 5732 participants. Our initial analysis indicated a significant positive association between WWI and PSA levels. However, subsequent models that adjusted for covariates such as age, race, and a range of metabolic and cardiovascular health-related factors revealed that the strength and significance of this relationship were attenuated. Model 1 showed a highly significant correlation (P < 0.0001). Yet, in Model 2, which accounted for age and race, the association softened (P = 0.0520). Moreover, when a full spectrum of health covariates was included in Model 3, the association was no longer significant (P = 0.9775). These findings suggest that while an unadjusted correlation exists, its potential use as a diagnostic predictor is limited without considering the broader health context. Therefore, it is crucial to review such data with multiple considerations in mind, and extensive attention should be paid to the evaluation of covariates.

Baseline phenotypes with preserved ß-cell function and high insulin concentrations have the best improvements in glucose tolerance after weight loss: results from the prospective DEXLIFE and EGIR-RISC studies.

BACKGROUND: Weight loss and lifestyle intervention improve glucose tolerance delaying the onset of type 2 diabetes (T2D), but individual responses are highly variable. Determining the predictive factors linked to the beneficial effects of weight loss on glucose tolerance could provide tools for individualized prevention plans. Thus, the aim was to investigate the relationship between pre-intervention values of insulin sensitivity and secretion and the improvement in glucose metabolism after weight loss. METHODS: In the DEXLIFE cohort (373 individuals at high risk of T2D, assigned 3:1 to a 12-week lifestyle intervention or a control arm, Trial Registration: ISRCTN66987085), K-means clustering and logistic regression analysis were performed based on pre-intervention indices of insulin sensitivity, insulin secretion (AUC-I), and glucose-stimulated insulin response (ratio of incremental areas of insulin and glucose, iAUC I/G). The response to the intervention was evaluated in terms of reduction of OGTT-glucose concentration. Clusters' validation was done in the prospective EGIR-RISC cohort (n = 1538). RESULTS: Four replicable clusters with different glycemic and metabolomic profiles were identified. Individuals had similar weight loss, but improvement in glycemic profile and ß-cell function was different among clusters, highly depending on pre-intervention insulin response to OGTT. Pre-intervention high insulin response was associated with the best improvement in AUC-G, while clusters with low AUC-I and iAUC I/G showed no beneficial effect of weight loss on glucose control, as also confirmed by the logistic regression model. CONCLUSIONS: Individuals with preserved ß-cell function and high insulin concentrations at baseline have the best improvement in glucose tolerance after weight loss.

[Prevalence and trends of low body weight among elderly population aged 60 years and above in China in 2002-2015].

OBJECTIVE: Understand the current situation and changing trends of low body weight in elderly population aged 60 years and above. METHODS: Data was collected from 2002 Chinese Nutrition and Health Survey, 2010-2013 Chinese Nutrition and Health Surveillance and 2015 Chinese Adult Chronic Disease and Nutrition Surveillance. Multi-stage stratified cluster random sampling was used for all surveys or surveillance. In 2002, 27 778 samples of people aged 60 and over were taken from 132 monitoring sites in mainland China. In 2010-2013, 34 581 subjects were selected from 150 monitoring points in mainland China. In 2015, 59 576 subjects were selected from 302 monitoring points in mainland China. Questionnaires collected basic information such as gender, and date of birth, and information such as height and weight were collected through physical examination. RESULTS: The prevalence of low body weight in the elderly aged 60 years and above showed a downward trend from 2002 to 2015 in China(P<0.01). The prevalence of low body weight decreased from 11.67% in 2002 to 5.19% in 2015. The prevalence of low body weight among males decreased from 11.51% in 2002 to 5.21% in 2015. The prevalence of low body weight among females decreased from 11.83% in 2002 to 5.17% in 2015. The prevalence of low body weight in the elderly aged 60 years and above showed an upward trend with age. The prevalence of low body weight in urban areas decreased from 5.85% in 2002 to 3.31% in 2015. The prevalence of low body weight in rural areas decreased from 16.25% in 2002 to 6.67% in 2015. The prevalence of low body weight in seven geographic regions of China decreased from 2002 to 2015. The prevalence of low body weight was highest in the elderly population aged 60 years and above in South China(9.49%(95%CI 8.61%-10.38%)) and lowest in North China(2.55%(95%CI 2.15%-2.95%)) in 2015. CONCLUSION: The prevalence of low body weight among the elderly aged 60 years and above in China decreased from 2002 to 2015. The prevalence of low body weight increased with age. The prevalence was higher in rural areas than in urban areas, and the prevalence in South China was higher than in other geographic regions.

Improvement in insulin sensitivity after switching from an integrase inhibitor-based regimen to doravirine/tenofovir disoproxil fumarate/lamivudine in people with significant weight gain.

OBJECTIVES: We performed an observational, retrospective, cohort study to assess changes in insulin sensitivity after a switch from dolutegravir/lamivudine (DOL/3TC) or bictegravir/emtricitabine/tenofovir alafenamide (BIC/F/TAF) to doravirine/tenofovir disoproxil fumarate/3TC (DOR/TDF/3TC) in virologically suppressed people living with HIV with recent significant weight gain. METHODS: All non-diabetic patients with HIV treated with DOL/3TC or BIC/F/TAF for ≥12 months, with HIV RNA <20 copies/mL, and with a weight increase ≥3 kg in the last year, who underwent a switch to DOR/TDF/3TC were enrolled into the study. Serum levels of glucose, insulin, and homeostasis model assessment of insulin resistance (HOMA-IR) index were evaluated every 6 months during a 12-month follow-up. RESULTS: Overall, 81 patients were enrolled: 41 were treated with DOL/3TC and 40 with BIC/F/TAF. At baseline, median HOMA-IR index was 3.18 and insulin resistance (HOMA-IR index >2.5) was present in 49 subjects (60%). At 12 months after the switch to DOR/TDF/3TC, change in mean serum glucose concentration was not significant, but the reduction in median concentration of insulin was significant (-3.54 mcrUI/L [interquartile range -4.22 to -2.87]; p = 0.012), associated with a significant reduction in mean HOMA-IR index (-0.54 [interquartile range -0.91 to -0.18]; p = 0.021). A significant reduction in total and low-density lipoprotein cholesterol was also reported, whereas decreases in mean body weight and mean body mass index were not significant. CONCLUSIONS: In our retrospective study in virologically suppressed people living with HIV treated with DOL/3TC or BIC/F/TAF and with recent weight gain, the switch to DOR/TDF/3TC led to a significant improvement in insulin sensitivity and plasma lipids, with a trend to decreased body weight.

Effect of using the snackability app on snack quality among US college students with overweight and obesity: A randomized controlled trial.

OBJECTIVE: To determine if using the Snackability app improves snack intake among college students. PARTICIPANTS: US college students with overweight/obesity were recruited in June 2020-April 2021. METHODS: A randomized controlled trial was conducted to test the Snackability app use for 12 wk on snack scores (calculated from the app) compared to controls. We also explored the effect on diet quality (Healthy Eating Index-2015) and weight. Outcomes were compared between the intervention and the control groups at 4, 8, and 12 wk using repeated measures ANOVA. RESULTS: Participants in the app group significantly increased snack score at week 4 (p < 0.001) and week 8 (p = 0.015) and increased HEI-2020 score (p < 0.001) at week 4 compared to controls. The first 4 wk had the highest app usage. No significant differences were seen in body weight. CONCLUSIONS: The Snackability app can be used as a tool to help improve snack and diet quality in this group.

Technical note: utilization of various allotment strategies to evaluate variation and replications required to detect statistical significance in nursery pig research.

A total of 720 barrows (line 200 × 400, DNA genetics) were used in two 42-d nursery trials (initially 6.20 ±â€…0.12 kg and 5.63 ±â€…0.16 kg, respectively) to evaluate strategies for allotting pigs to pens in randomized controlled trials. At placement, the population was split into three cohorts with similar average weight and standard deviation and randomly assigned to one of the three allotment strategies. Strategy 1 (random) utilized a simple randomization strategy with each pig randomized to pens independent of all other pigs. Strategy 2 (body weight [BW] distribution) sorted each pig within the cohort into one of the five BW groups. One pig from each weight group was then randomly assigned to a pen such that distribution of BW within pen was uniform across pens. Strategy 3 (BW grouping) sorted pigs within the cohort into 3 BW categories: light, medium, and heavy. Within each BW category, pigs were randomized to pen to create pens of pigs from each BW category. Within each experiment, there were 72 pens with five pigs per pen and 24 pens per allotment strategy. For all strategies, once pigs were allotted to pens, pens were allotted to one of the two treatments for a concurrent trial. In experiment 1, environmental enrichment using ropes tied near the pan of the feeder was compared to a control with no enrichment. In experiment 2, treatment diets consisted of basal levels of Zn and Cu from the trace mineral premix for the duration of the study (110 and 17 mg/kg, respectively; control), or diets (supplemented control) with carbadox (50 g/ton; Mecadox, Phibro Animal Health, Teaneck, NJ) fed in phase 1 (days 0 to 22) and 2 (days 22 to 43), pharmacological levels of Zn and Cu (2,414 mg/kg Zn from ZnO; 168 mg/kg Cu from CuSO4) fed in phase 1, and only pharmacological levels of Cu (168 mg/kg Cu from CuSO4) fed in phase 2. These treatment designs were used to determine the impact on coefficient of variation (CV) and to estimate the number of replications required to find significant treatment differences based on allotment strategy. There were no meaningful allotment strategy × treatment interactions for either study. For between-pen CV, pigs allotted using BW distribution and BW grouping strategies had the lowest CV at allotment and final weight in both trials. For overall average daily gain in experiments 1 and 2 in experiment 2, the BW distribution strategy required the fewest replications to detect differences in performance. However, there is no meaningful difference between allotment strategies in replications required to detect significant differences for gain:feed ratio.

Decreasing variation between experimental units increases the likelihood of finding a statistically significant difference if one exists. Assignment of animals to experimental units (pens) may contribute to that variation. Therefore, the purpose of this trial was to investigate the effect that different methods of allotting pigs to pens (experimental unit) have on variation and in turn, the number of replications required to detect a significant difference of a given amount between treatments. The random strategy assigned pigs to pens in a completely random fashion. The body weight (BW) distribution strategy ordered pigs from lightest to heaviest and created five groups based on BW. Each pen was randomly assigned one pig from each of the five groups. The BW grouping strategy again ordered pigs from lightest to heaviest but split pigs into three groups based on BW and each pen was randomly assigned pigs from only one BW group such that there were pens of light pigs, pens of medium pigs, and pens of heavy pigs. Ultimately, the best allotment strategy depends on the parameter of interest. For final BW and overall ADG, the BW grouping method required the fewest pens to detect statistically significant differences.

Inhibitory effect of stinging nettle (Urtica dioica L.) extract on body weight gain in rats on a high-fat diet.

Introduction: The leaves and seeds of Urtica dioica (UD) are used in folk treatments for many diseases. Anticarcinogenic, anti-inflammatory, antioxidant, and antiallergenic properties of UD have been reported. Aim: To uncover the effects of nettle seed (Urtica dioica; UD) extract on body weight gain in rats on a high-fat diet (HFD). Material and methods: Male Wistar albino rats (n = 32) were divided into 4 groups, comprising a control group, a group that received a HFD (HFD group), a group that received UD extracts (UD group), and a group that received a HFD as well as UD extracts (HFD + UD group). UD extracts were given a daily dose of 300 mg/kg of body weight orally for 75 days. Results: The HFD led to weight gain that was partially moderated by the UD extract. Histopathological findings in the HFD + UD group were uniformly significantly lower than those in the HFD group. Serum alanine transaminase, alanine aminotransferase, triglyceride, and low-density lipoprotein levels were significantly higher in the HFD group than in the HFD + UD group, and the HDL levels were lower in the HFD group than in the control group and the HFD + UD group. Conclusions: The cholesterol levels were discovered to be highest in the HFD + UD group. Therefore, it was concluded that the UD extract did not completely protect the rats against body weight gain.

Biological and environmental factors influencing reproductive performance in ICR mice, Mus musculus.

BACKGROUND: Since strain names and breeding facilities of ICR mice used in 37 reproductive toxicity studies have changed from 1990 to 2022 in our laboratory, biological and environmental factors that affect reproductive parameters were investigated in control mice to examine the validity of the background data. METHODS: Litter size and sex ratio were measured at birth [postnatal day (PND) 0], while offspring body weight was measured on PND 0 and 21 during the lactation. The relationships between biological and environmental factors and reproductive parameters were assessed with multiple regression analysis using stepwise regression as an explanatory variable selection strategy. The biological factors of litter size at birth, secondary sex ratio (male%), body weight (g) at birth and strain name, and environmental factors of facilities (room), temperature/humidity, and bedding materials were used as explanatory variables, and reproductive parameters of litter size at birth, secondary sex ratio (male%), body weight (g) at birth, and survival index (%) of offspring at PND 21 were used as response variables. RESULTS: No significant effects were indicated in litter size and sex ratio (male %) with any biological and environmental factors. Male and female offspring weights were significantly affected by strain names. No significant effects were indicated in the survival index (%) at PND 21 in both sexes with any biological and environmental factors. CONCLUSIONS: Litter size and sex ratio in this report are sufficient as background data throughout the period because no significant variables of biological and environmental factors affected litter size and gender composition.

Effect of a microencapsulated phyto/phycogenic blend supplementation on growth performance, processing parameters, meat quality, and sensory profile in male broilers.

Powered by consumer taste, value, and preferences, natural products including phytogenics and algae are increasingly and separately used in the food systems where they have been reported to improve growth performance in poultry and livestock. The present study aimed to determine the effects of a new feed additive, microencapsulated NUQO© NEX, which contains a combination of phytogenic and phycogenic, on broiler growth performance, blood chemistry, bone health, meat quality and sensory profile. Male Cobb500 chicks (n = 1,197) were fed a 3-phase feeding intervals; 1-14d starter, 15-28d grower, and 29-40d finisher. The dietary treatments included a corn-soy basal Control (CON), basal diet supplemented with NUQO© NEX at 100 g/ton from 1 to 28d then 75 g/ton from d 28 to 40 (NEX75), and basal diet supplemented with NUQO© NEX at 100 g/ton from 1 to 40d (NEX100). The NEX100 supplemented birds had 62 g more BWG increase and 2.1-point improvement in FCR compared with CON in the finisher and overall growth phase (p < 0.05), respectively. Day 40 processing body weights and carcass weights were heavier for the NEX100 supplemented birds (p < 0.05). The incidences of muscle myopathies were also higher in NEX treatments, which could be associated with the heavier weights, but the differences were not detected to be significant. The NEX75 breast filets had more yellowness than other dietary treatments (p = 0.003) and the NEX 100 treatment reduced the levels of breast filet TBARS at 7 days-post harvest (p = 0.053). Finally, both NEX treatments reduced the incidence of severe bone (tibia and femur) lesions. In conclusion, the supplementation of the phytogenic NUQO© NEX improved finisher performance parameters, whole phase FCR, processing carcass weights, and breast filet yellowness, at varying inclusion levels.

Interevaluator reliability of a tool for measuring body height in adult intensive care patients.

BACKGROUND: The calculation of body height in the intensive care unit is essential for obtaining the ideal body weight, which is used to program the tidal volume and establish objective and effective pulmonary ventilation. The objective of the study was to determine the interrater reliability of a tool for measuring body height in adult patients in an intensive care unit (ICU) in southwestern Colombia. METHODS: This cross-sectional observational study was conducted between January and May 2021, following the recommendations of the COSMIN protocol. Two physiotherapists in the roles of observer/evaluator measured the heights of 106 patients upon admission to the ICU with a previously designed. The sample size was calculated based on Pearson's correlation coefficient. For interrater reliability, the intraclass correlation coefficient (ICC) was used, and Bland-Altman analysis was used to assess concordance. The 95% confidence interval was established, and a P value <0.05 indicated statistical significance. RESULTS: A total of 106 individuals with a mean age of 59.3 years were included; the mean body height was 158.5 cm for women. The interrater reliability of the measurement of height was excellent (global ICC of 0.99, P = 0.000), and an almost perfect positive correlation was obtained between the raters for both women and men (R = 0.99). CONCLUSIONS: Excellent interrater/interobserver reliability was obtained for the measurement of body height in the ICU.

The Impact of Quarantine on Physical Activity, Body Weight, and Eating Behaviors During the COVID-19 Pandemic in Saudi Arabia.

Background Since February 2020, the number of coronavirus disease 2019 (COVID-19) cases in Saudi Arabia has been rising. The Saudi Arabian government implemented strict lockdown measures in March 2020 in an effort to stop the spread of the virus. Globally, changes in socioeconomic levels and health during quarantine have been reported. Additional detrimental effects of the stay-at-home mandate include less physical activity among adult populations, anxiety, stress, and emotional eating. This study aimed to assess the impact of quarantine during the COVID­19 pandemic on physical activity practice and weight. Methodology This cross-sectional study was conducted using a newly developed validated online questionnaire survey. The data were collected during quarantine in June 2020, including each adult who lived in Saudi Arabia during the quarantine. The data were reviewed and analyzed using SPSS version 21 (IBM Corp., Armonk, NY, USA). Results A total of 4,970 eligible participants completed the study survey. About 78.1% of the study participants performed physical activity inside the house during the pandemic. Overall, 30.9% reported increased body weight during the lockdown, and the most reported cause of increased body weight was feeling bored and empty. Regarding factors associated with physical activity and weight changes, 82.2% of participants aged 25-30 years performed physical activity during the pandemic. Increased weight was significantly higher among participants aged more than 30 years. Conclusions This study shows an increased level of physical activity among the study participants during the COVID-19 pandemic, especially among younger, female, and unmarried participants. More than half of the participants reported weight change, either weight gain or weight loss. Weight gain was higher in older participants. Regarding eating habits, there was an increased tendency toward eating a healthy diet.

Are turkey hens affected by light flicker? Effects on performance and health.

Light flicker is a commonly overlooked factor of artificial light sources. This study aimed to determine the impacts of light-flicker frequency on performance, general health, and mortality of 11-wk Nicholas Select turkey hens. The experiment consisted of 2 trials (block) in a randomized complete block design, with 3 light-flicker frequency treatments (30, 90, or 195 Hz). Turkeys (n = 364 per replicate) were randomly placed into environmentally controlled rooms (3 room replicates per treatment per trial). Group body weight (BW) and feed consumption were measured at 0, 4, 8, and 11 wk, and feed efficiency (mortality corrected feed-to-gain; F:Gm) was calculated for each period. Mortality and culls were collected twice daily. Flock uniformity, feather condition and cleanliness, footpad score, and mobility were evaluated at 10 wk (30 birds per room). Litter quality and ocular weight and dimensions were evaluated (11 wk; 4 birds per room). Data were analyzed using Proc Mixed (SAS 9.4) and significance was declared when P < 0.05. At 8 wk, BW was lower under 30 Hz compared to 195 Hz (P = 0.03). Feed consumption was lowest under 30 Hz (0-4 wk and 4-8 wk; P < 0.01). Mortality-corrected F:G was improved under 30 Hz for 8 to 11 wk and 0 to 11 wk (P = 0.05 and P = 0.04, respectively). Total mortality was lower under 195 Hz compared to 30 Hz (P = 0.02). Uniformity, gait score, feather condition, and litter quality were unaffected by flicker. Footpad scores were improved under 90 Hz (P = 0.01), leading to an improved average footpad score (P = 0.02). Feather cleanliness was improved under 90 Hz compared to both 30 Hz and 195 Hz (P<0.01). Right eyeball dimensions differed across lighting treatments, with the dorso-ventral diameter being larger in birds under 30 Hz compared to 195 Hz (P = 0.05). The anterior-posterior size also increased in birds under 30 Hz compared to 90 Hz (P = 0.03). Light flicker impacted turkey hens, with the results demonstrating negative impacts on early growth and changes to ocular characteristics.

Health Benefits of Different Sports: a Systematic Review and Meta-Analysis of Longitudinal and Intervention Studies Including 2.6 Million Adult Participants.

BACKGROUND: Several reviews have examined the health benefits of participation in specific sports, such as baseball, cricket, cross-country skiing, cycling, downhill skiing, football, golf, judo, rugby, running and swimming. However, new primary studies on the topic have recently been published, and the respective meta-analytic evidence needs to be updated. OBJECTIVES: To systematically review, summarise and appraise evidence on physical health benefits of participation in different recreational sports. METHODS: Searches for journal articles were conducted in PubMed/MEDLINE, Scopus, SpoLit, SPORTDiscus, Sports Medicine & Education Index and Web of Science. We included longitudinal and intervention studies investigating physical health outcomes associated with participation in a given sport among generally healthy adults without disability. RESULTS: A total of 136 papers from 76 studies conducted among 2.6 million participants were included in the review. Our meta-analyses of available evidence found that: (1) cycling reduces the risk of coronary heart disease by 16% (pooled hazard ratio [HR] = 0.84; 95% confidence interval [CI]: 0.80, 0.89), all-cause mortality by 21% (HR = 0.79; 95% CI: 0.73, 0.84), cancer mortality by 10% (HR = 0.90; 95% CI: 0.85, 0.96) and cardiovascular mortality by 20% (HR = 0.80; 95% CI: 0.74, 0.86); (2) football has favourable effects on body composition, blood lipids, fasting blood glucose, blood pressure, cardiovascular function at rest, cardiorespiratory fitness and bone strength (p < 0.050); (3) handball has favourable effects on body composition and cardiorespiratory fitness (p < 0.050); (4) running reduces the risk of all-cause mortality by 23% (HR = 0.77; 95% CI: 0.70, 0.85), cancer mortality by 20% (HR = 0.80; 95% CI: 0.72, 0.89) and cardiovascular mortality by 27% (HR = 0.73; 95% CI: 0.57, 0.94) and improves body composition, cardiovascular function at rest and cardiorespiratory fitness (p < 0.010); and (5) swimming reduces the risk of all-cause mortality by 24% (HR = 0.76; 95% CI: 0.63, 0.92) and improves body composition and blood lipids (p < 0.010). CONCLUSIONS: A range of physical health benefits are associated with participation in recreational cycling, football, handball, running and swimming. More studies are needed to enable meta-analyses of health benefits of participation in other sports. PROSPERO registration number CRD42021234839.
