Impact of carbimazole combined with vitamin E on testicular injury induced by experimental hyperthyroidism in adult albino rats: oxidative/inflammatory/apoptotic pathways.

Thyroid hormones play essential roles in spermatogenesis, but their effects on infertile males remain poorly understood. This study aimed to evaluate the impact of combining carbimazole (CBZ) with vitamin E (VE) on testicular injury induced by experimental hyperthyroidism in adult albino rats, focusing on oxidative, inflammatory, and apoptotic pathways. In this experimental study, 64 adult male albino Wistar rats were divided into eight groups: Group I (control-untreated), Group II (CBZ-control), Group III (VE-control), Group IV (CBZ + VE-control), Group V (levothyroxine-induced testicular injury), Group VI (levothyroxine + CBZ-treated), Group VII (levothyroxine + VE-treated), and Group VIII (levothyroxine + CBZ + VE-treated). The study was conducted in the Faculty of Medicine, Suez Canal University (Ismailia, Egypt). After cervical decapitation, both testes and epididymis were examined histopathologically and immunohistochemically. Significant differences were observed among groups concerning malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), and catalase (CAT; all P < 0.001). Polymerase chain reaction analysis showed significant differences in tumor necrosis factor-α (TNF- α ), interleukin-10 (IL-10), Bcl-2-associated X protein (BAX), B-cell lymphoma 2 protein (Bcl2), p53, Caspase-3, Caspase-8, Caspase-9, and nuclear factor-kappa B (NF- κ B) mRNA levels (all P < 0.001). Hyperthyroid group treated with CBZ alone (Group VI) exhibited testicular side effects, affecting seminiferous tubules and spermatogenesis. However, the Group VIII showed improved spermatogenesis and a decrease in testicular side effects. The addition of VE to the treatment of hyperthyroid rats with CBZ reduced testicular side effects and seminiferous tubular affection when potentially improving spermatogenesis. Further research is needed to elucidate the underlying mechanisms fully.

Is thyroid dysfunction a common cause of telogen effluvium?: A retrospective study.

Telogen effluvium (TE) is a common cause of hair loss characterized by excessive resting hair shedding. Thyroid dysfunction is one of the possible causes of TE. On the other hand, the link between thyroid disorder and TE is still being debated. The aim of this retrospective is to investigate the link between thyroid dysfunction and TE. This retrospective study included 500 female patients with TE who had thyroid function testing between January 2012 and December 2022. Patients were eligible if they had a confirmed TE diagnosis and thyroid function tests within 3 months of being diagnosed with TE. The thyroid function of the participants was classified as euthyroid, hypothyroidism, or hyperthyroidism. The severity of hair loss was determined using the severity of alopecia tool (SALT) score. The study included 500 TE females, 248 of whom were euthyroid, 150 had hypothyroidism, and 102 had hyperthyroidism. The hypothyroid group had a significantly higher mean SALT score than the other 2 groups. Furthermore, patients in the hypothyroid group had a higher proportion of severe hair loss. The mean SALT score did not differ significantly between groups with normal thyroid function and those with hyperthyroidism. A common cause of TE is thyroid dysfunction, particularly hypothyroidism. Patients with hypothyroidism have more severe hair loss than those with normal thyroid function or hyperthyroidism. To effectively identify and manage such cases, thyroid function testing should be included in the diagnostic workup of patients with TE.

Botulinum Toxin A for Hair Loss Treatment: A Systematic Review of Efficacy, Safety, and Future Directions.

Background: Hair loss is a common condition with significant impact globally, yet its treatment efficacy and safety remain debated. Botulinum toxin A (BoNT-A) has emerged as a potential therapeutic option, but a comprehensive review on this topic is lacking. Objective: This review critically evaluates the current evidence on BoNT-A for hair loss treatment, highlighting the gaps in previous reviews and providing a comprehensive analysis of its efficacy, safety, and future prospects. Methods: A systematic search of electronic databases identified relevant studies published up to September 2022. Results: Prior reviews primarily focused on androgenetic alopecia and lacked the evaluation of other alopecia types and underlying mechanisms. Our review addresses this gap, incorporating a broader spectrum of hair loss conditions. Mechanisms of BoNT-A in hair growth modulation, potential side effects, and future research directions are discussed. Conclusion: This review adds to the existing body of knowledge by providing a comprehensive evaluation of BoNT-A in hair loss treatment. The findings will serve as a foundation for further research and guide clinicians in making informed decisions, ultimately improving the outcomes and quality of life for individuals suffering from hair loss.

Impact of Thyroid Dysfunction on Hair Disorders.

Hair loss is a problem for everyone, regardless of their age or sex. The three most prevalent types of hair loss, telogen effluvium, alopecia areata, and androgenetic alopecia, have been associated with a variety of risk factors. Strong evidence links thyroid hormones (THs) to hair loss. THs control the growth, differentiation, metabolism, and thermogenesis of body cells. The skin is a significant target organ for THs; however, the cellular and molecular causes of thyroid dysfunction-related skin diseases remain unknown. Hyperthyroidism, hypothyroidism, and drug-induced hypothyroidism can induce widespread hair shedding. Little information is available regarding the incidence and effects of thyroid dysfunction on hair problems. This study aimed to review the impact and prevalence of thyroid disorders on hair loss. The conclusions drawn from this study highlight the underestimated prevalence and impact of thyroid disorders on hair loss. The review of scientific articles, including original research, review articles, and a case report, provides a comprehensive understanding of the topic. This research adds to the existing literature by enhancing our understanding of the relationship between thyroid dysfunction and hair disorders. It contributes to the body of evidence by reviewing relevant studies and summarizing the impact of thyroid disorders on hair loss. The study also highlights the gaps in knowledge and the need for more research in this area to improve the diagnosis and management of hair disorders associated with thyroid dysfunction.

Polyphenols Mediate Neuroprotection in Cerebral Ischemic Stroke-An Update.

Stroke is one of the main causes of mortality and disability, and it is due to be included in monetary implications on wellbeing frameworks around the world. Ischemic stroke is caused by interference in cerebral blood flow, leading to a deficit in the supply of oxygen to the affected region. It accounts for nearly 80-85% of all cases of stroke. Oxidative stress has a significant impact on the pathophysiologic cascade in brain damage leading to stroke. In the acute phase, oxidative stress mediates severe toxicity, and it initiates and contributes to late-stage apoptosis and inflammation. Oxidative stress conditions occur when the antioxidant defense in the body is unable to counteract the production and aggregation of reactive oxygen species (ROS). The previous literature has shown that phytochemicals and other natural products not only scavenge oxygen free radicals but also improve the expressions of cellular antioxidant enzymes and molecules. Consequently, these products protect against ROS-mediated cellular injury. This review aims to give an overview of the most relevant data reported in the literature on polyphenolic compounds, namely, gallic acid, resveratrol, quercetin, kaempferol, mangiferin, epigallocatechin, and pinocembrin, in terms of their antioxidant effects and potential protective activity against ischemic stroke.

Optimization of pulmonary function, functional capacity, and quality of life in adolescents with thoracic burns after a 2-month arm cycling exercise programme: A randomized controlled study.

BACKGROUND: Burns to the thorax are at high risk for long-term pulmonary complications due to chest muscle contractures and chronic inflammation in both adolescents and young adults. Few studies have investigated the effects of arm cycling exercise in those individuals. For that reason, this study examined pulmonary function, functional capacity, and quality of life (QOL) in adolescents with thoracic burns subsequent to 2-month arm cycling exercise programme. METHODS: A single-blinded, two-month randomized prospective controlled study was carried out between July 2019 and March 2020 on thirty adolescents with chest burns aged 11-17 years. They were randomized into two equal groups (n = 15), traditional physiotherapy programme (control group), and arm cycling exercise plus traditonal physiotherapy (arm cycling exercise group) for 2 consecutive months. Forced vital capacity (FVC), forced expiratory volume in one second (FEV1), six-minute walk test (6MWT), and Pediatric Quality of Life Inventory (PedsQL) were measured in both groups at baseline and after 2-month after intervention. RESULTS: No statistical significance was detected at baseline between control and arm cycling exercise groups (FVC, p = 0.903, FEV1, p = 0.835, 6MWT, p = 0.817, and PedsQL, p = 0.612). 2 months after intervention showed statistical improvements in the arm cycling exercise group in all measures (FVC, p = 0.001, FEV1, p < 0.0001, 6MWT, p = 0.001, and PedsQL, p = 0.001) however, the control group showed statistical improvements in FVC, p = 0.044 and FEV1, p = 0.024 with non-statistically significant changes in 6MWT, p = 0.145 and PedsQL, p = 0.067. The arm cycling exercise group showed greater improvements than control group in the outcome measures (FVC, p = 0.034, FEV1, p < 0.017, 6MWT, p = 0.037, and PedsQL, p = 0.021). CONCLUSIONS: This prospective study clearly demonstrated positive and beneficial influences of two-month arm cycling exercise in the optimization of pulmonary functions, functional performance, and QOL in adolescents suffering from chest burns and thereby eliminating post-burn complications.

Efficacy of combination of biofeedback therapy and pelvic floor muscle training in dyssynergic defecation.

BACKGROUND: It is now known that with appropriate exercises, the functions of the muscles in the body ameliorate and increase in strength. We applied pelvic floor muscle relaxation training and exercises that strengthen the abdominal and pelvic muscles in combination with biofeedback therapy (BFT) to patients with dyssynergic defecation (DD). METHODS: Patients who met the criteria for DD and had no underlying organic cause were included in this study. The electromyography (EMG) technique was used for BFT therapy. Patients had received at least six sessions of BFT. BFT was considered successful in patients when the DD pattern in anorectal manometry (ARM) disappeared and/or adequate anal relaxation was obtained following BFT and in patients who had full clinical recovery. RESULTS: Data of 104 patients (58 females [55.8%] and 46 males [44.2%]) was evaluated. Abdominal and rectal symptoms disappeared in 71 (68.26%) patients. Of the patients who achieved symptomatic improvement, 58 (55.76%) saw a disappearance of the dyssynergic defecation pattern. When the differences between anal sphincter pressures before and after treatment were compared in patients who responded to BFT and those who did not, no significant differences were observed, but significant changes were found in anal squeezing pressures. It was found that those who had high squeezing pressures before BFT, those who increased their squeezing pressures after BFT, and those who decreased their resting pressure responded better to BFT. CONCLUSIONS: In this study, BFT was found to be more effective in those with a high squeezing pressure and those that increased squeezing pressure after BFT. These findings will influence the treatment of patients with dyssynergic defecation who do not respond to treatment. A combination of abdominal and pelvic floor muscle exercises and BFT increases patient response.

Primary upper extremity deep vein thrombosis (effort thrombosis).

Primary spontaneous upper extremity deep vein thrombosis is characterised by thrombosis within deep veins draining the upper extremity due to anatomical abnormalities of the thoracic outlet causing axillosubclavian compression and subsequent thrombosis. It is an uncommon condition that typically presents with unilateral arm swelling in a young male following vigorous upper extremity activity. The diagnosis of this condition is usually made by Doppler ultrasound, but other investigations are mandatory to exclude the secondary causes of upper extremity DVT. Different treatment options are available including anticoagulation, thrombolysis, and surgery. We report the case of a young healthy male with athletic physique who presented with pain and swelling of his dominant arm after weightlifting in the gym.

Can we estimate cytokine storm from initial computed tomography images of Coronavirus disease-2019 patients?

OBJECTIVES: The present study aims to investigate whether elementary lesions detected at the time of the diagnosis, their distribution characteristics, and CT scoring can be predictive of a cytokine storm. BACKGROUND: CT might have a prognostic predictive value beyond its diagnostic value. METHODS: Sixty-eight patients, 32 with cytokine storm and 36 without cytokine storm, were included in the study. Four different scoring methods were created according to elementary lesions, distribution and involvement rate. CT scores and demographic findings of the cases were compared in the cytokine storm and non-cytokine storm groups. RESULTS: The mean age of patients was 57.72 (SD: 13.5) and 40 (58.8 %) of them were male. The cytokine storm was significantly more common among male patients and patients of older age (p=0.04).  The AUC values of CT score 1, CT score 2, CT score 3, and CT score 4 were as follows; 0.772 (95% CI; 0.651-0.892), 0.766 (95% CI; 0.647-0.885), 0.758 (95% CI; 0.639-8.78), and 0.760 (95% CI; 0.640-0.881), respectively. All CT scores had better predictive values in males. CONCLUSIONS: CT scoring at the time of admission can be used to predict cases that may develop cytokine storm later (Tab. 4, Fig. 2, Ref. 15).

Palmar psoriasis or missed BCC?-A case report.

CASE REPORT: A 76-year-old Caucasian woman with a history of previous BCCs excised from the head and legs was referred from the dermatology team with a biopsy proven superficial BCC to the left palm. The patient had presented to the dermatology team with the same lesion 7 years prior to the definitive diagnosis. The lesion was described as 27 × 15 mm scaly, poorly-defined, plaque-like lesion to the central palm. There was no ulceration or visible telangiectasia. At the time, an initial diagnosis of psoriasis was given and she received several courses of topical treatments to no avail. Eventually, a biopsy was taken which revealed a multifocal superficial BCC. After unsuccessful attempts at treating with topical Imiquimod, the lesion was surgically excised and resurfaced with a full thickness skin graft. DISCUSSION: The current understanding that BCCs derive from cells of the hair follicle cannot explain their appearance on the palm. Alternative hypotheses have been proposed as to their actual origin which would account for this rare occurrence. Ultimately, histology can determine the nature of the lesion. We urge clinicians encountering atypical, non-healing lesions to glabrous skin to keep in mind a diagnosis of skin cancer as a delayed diagnosis can lead to increased morbidity.

Yoga in Burn: Role of pranayama breathing exercise on pulmonary function, respiratory muscle activity and exercise tolerance in full-thickness circumferential burns of the chest.

BACKGROUND: Circumferential burn of chest (CBC) is a significant type of burn and considers as a major cause of restrictive lung disease (RLD). Patient who has CBC with RLD leads to respiratory symptoms such as breathing difficulty, airway obstruction, reduced exercise capacity and altered pulmonary functions. However, studies examining the role of pranayama breathing exercise on pulmonary function, respiratory muscle activity and exercise tolerance in full thickness circumferential burn of chest are lacking. OBJECTIVE: To find the short term effects of pranayama breathing exercise on pulmonary function, respiratory muscle activity and exercise tolerance in full thickness circumferential burns of chest. METHODS: Through simple random sampling method thirty subjects (N = 30) with RLD following CBC were allocated to pranayama breathing exercise group (PBE-G; n = 15) and conventional breathing exercise group (CBE-G; n = 15). They received pranayama breathing exercise and conventional breathing exercise for 4 weeks respectively. All the subjects received chest mobility exercise as common treatment. Primary (Numeric Pain Rating Scale - NPRS, forced expiratory volume (FEV1), forced vital capacity (FVC) and maximum voluntary ventilation (MVV) and secondary (Electromyogram of sternocleidomastoid, scalene, external intercostal and diaphragm muscle, 6 min walk test & Global Rating of Change - GRC) outcome measures were measured at baseline, after four weeks and after three months follow up. RESULTS: Baseline demographic and clinical variables show homogenous distribution between the groups (p > 0.05). Four weeks following different breathing exercises, PBE-G group shows more significant changes in pain intensity, pulmonary function, respiratory muscle activity, exercise tolerance and global rating of change than CBE-G group (p ≤ 0.05) at four weeks and three months follow up. CONCLUSION: Both groups showed improvement over time. However, differences between the groups were noticed small. Still physiotherapy management, which included pranayama breathing exercises with chest mobilization program, had an effective strategy in the treatment of restrictive lung disease following circumferential burn of chest.

Shear wave elastography of the submandibular gland in healthy individuals.

OBJECTIVES: Shear wave elastography is a rapidly evolving new technique. The purpose of the present study was to determine the sonoelastographic features of the submandibular glands in healthy individuals. METHODS: We conducted a cross-sectional study of 45 healthy individuals, whose submandibular glands were studied using shear wave elastography. The stiffness of both submandibular glands was measured and its relationships with the age, sex, body mass, body mass index (BMI), and height of the participants were assessed. RESULTS: The participants had a mean age of 31.82 ± 5.53 years, a mean height of 158.30 ± 7.16 cm, a mean body mass of 57.83 ± 8.84 kg, and a mean BMI of 22.99 ± 2.72 kg/m2. The mean shear elastic modulus of the right and left submandibular glands were 18.02 kPa and 19.09 kPa, respectively. Positive correlations were found between the elasticity of the right submandibular gland and the anthropometric parameters. CONCLUSION: The elastic modulus of the submandibular glands has been determined in healthy individuals and the data generated can serve as a reference for future studies of pathological conditions of these structures.

Effect of essential oils on the immune response to some viral vaccines in broiler chickens, with special reference to Newcastle disease virus.

This trial assessed the efficacy of a commercial essential oil (EO) product on the immune response to vaccination against Newcastle disease (ND) and subsequent challenge with virulent ND virus genotype VII (vNDv genotype VII) by using the following experimental groups of broiler chickens (Each group had 21 birds with 3 replicates in each, n = 7): NC (negative control), PC (positive control), VC (vaccinated), and VTC (vaccinated and treated with EOs). Moreover, in a trial to study the effect of EOs on vNDv genotype VII in vivo as a preventive or therapeutic measure, 2 additional ND-vaccinated groups were used (PRV: medicated 1 D before vNDv challenge for 5 D; and TTT: medicated 2 D after vNDv challenge for 5 D). In addition, the immune-modulatory effect of EOs on the avian influenza (AI), infectious bronchitis (IB), and infectious bursal disease (IBD) vaccines was assessed through the serological response. The use of EOs along with administration of ND vaccines (VTC) revealed a lower mortality rate (42.86%), clinical signs, and postmortem lesion score (11) than ND vaccines alone (VC) (52.28% mortality and score 15), in addition to lower hemagglutination inhibition (P < 0.05) (6.5 ± 0.46) and viral shedding (10 log 2.28 ± 0.24) titres 1 wk after challenge in comparison with VC (8.63 ± 0.65 and 10 log 3.29 ± 0.72, respectively). Nevertheless, the EOs mixture (VTC) (1952 ± 28.82) did not significantly (P > 0.05) improve growth performance compared with the nontreated birds (NC and VC) (1970 ± 19.56 and 1904 ± 38.66). EOs showed an antiviral effect on vNDv in vivo (in chickens) as a preventive measure (PRV) as well as some therapeutic effect (TTT) through decreasing the viral shedding titres (loNC0), mortality rate, and severity of clinical signs and postmortem lesions, in addition to serum malondialdhyde level. Regarding the other viruses, the EOs mixture did not improve the immune response to the AI and IB vaccines but significantly (P < 0.05) increased the ELISA antibody titre for IBD virus at the 28th D of age (2,108 ± 341.05). The studied EOs mixture showed an immune-stimulating response to ND and IBD vaccines, antiviral effect against ND virus, especially if administered before the challenge; however, it did not have a growth-promoting effect.

Effects of supplementing broiler diets with coriander seed powder on growth performance, blood haematology, ileum microflora and economic efficiency.

A total of 480 one-day-old Arbor Acres broiler chicks were randomly assigned to four dietary groups, each including six replicates (n = 20/replicate). Broilers in the first group (G1) were fed a basal diet without any additives (control). Broilers in groups 2, 3 and 4 (G2, G3 and G4) were fed a basal diet supplemented with 0.1%, 0.2% and 0.4% coriander (Coriandrum sativum L.) seed powder (CSP) respectively. Feeding trials lasted for 42 days, and after that growth, carcass traits, haematological parameters, gut microbiota and economic efficiency (EE) were evaluated. Final body weight (FBW), total weight gain (TWG), total feed intake (TFI) and red blood cell (RBC) counts of broilers in the G4 and G3 treatment groups were significantly higher (p < .05) compared with broilers in the G1 treatment group. The feed conversion ratio (FCR) was better (p < .05) in the G4 treatment group (1.72) than in the G1 treatment group (1.84). Broilers in CSP treatment groups had significantly higher haemoglobin (Hb) concentrations, packed cell volume (PCV) and platelet counts, and had lower (p < .05) Escherichia coli and Clostridium perfringens counts compared with broilers in the G1 treatment group. Dressing, liver, pancreas, bursa and thymus percentages were higher (p < .05) in broilers in the G4 (70.30, 3.18, 0.31, 0.10 and 0.32% respectively) treatment group, compared with broilers in the control (G1) group (66.57, 2.37, 0.23, 0.04 and 0.21% respectively). Broilers in treatment groups G4 and G3 had lower percentages of abdominal fat and lower total bacterial counts (p < .05) than broilers in treatment groups G2 and G1. The highest economic efficiency (EE) was found in treatment group G4, and EE in this group was 13.06% greater than in the control (G1) group.

Laying Performance, Physical, and Internal Egg Quality Criteria of Hens Fed Distillers Dried Grains with Solubles and Exogenous Enzyme Mixture.

: The effects of dietary inclusion of distillers dried grains with solubles in laying hen diets with and without exogenous enzyme mixture (EEM) on performance and egg characteristics were evaluated. One of the main objectives of this study was to examine the effects of distillers dried grains with solubles (DDGS) and enzyme cocktail on egg yolk fatty acids. The study used total of 144 Hisex Brown laying hens in a 4 × 2 factorial arrangement, including four levels of DDGS (0, 6, 12, and 18% of diet) and two levels of enzyme cocktail (0 or 250 mg EEM/kg of diet) through 32⁻42 weeks of the age. The inclusion of 18% DDGS was associated with the worst (p ≤ 0.001) egg production and the lowest daily feed intake. Numerically, hens fed 6% DDGS diet consumed more feed and had the greatest egg production. The best feed conversion ratio (FCR) was recorded in the control, while the worst was recorded in the 18% DDGS group. Compared with EEM-free diets, EEM supplementation improved FCR by about 2.79%, but the difference was not significant. Shell thickness and shell percentage were significantly increased in hens fed 6% DDGS diet compared to other groups. Egg weights in the 6% and 12% DDGS groups were significantly higher than those in the control and 18% DDGS groups. Non-significant increases in shell and albumin percentages were recorded in groups fed EEM-supplemented diets. The interaction effect of DDGS and EEM was significant (p ≤ 0.01) for the majority of egg characteristics. As dietary DDGS level increased, yolk color density increased. Elevating DDGS level up to 18% increased yolk cholesterol, total fat, and total unsaturated fatty acids. The effects of EEM supplementation on egg yolk fatty acid composition and the interaction effects between DDGS and EEM were not significant. Considering these results, it could be concluded that DDGS is an acceptable feed ingredient in layer diets and that the maximum inclusion level of DDGS should not exceed 12% of the whole diet.

Miswak (Salvadora persica) dietary supplementation improves antioxidant status and nonspecific immunity in Nile tilapia (Oreochromis niloticus).

Nile tilapia (Oreochromis niloticus) is the most common aquaculture fish, but is exposed to various pollutants and may be susceptible to infectious diseases due to reduction in their antioxidant status and immune defense. Therefore, researchers have tried to find feed supplements of natural origin to increase the health status of fish and decrease the incidence of drug resistance. The current study was conducted to investigate the effect of dietary supplementation of Miswak (Salvadora persica, SP) on Nile tilapia. Fish were randomly allocated into four experimental groups (30 fish each); the control fish were fed on the basal commercial diet and the SP-treated groups were fed basal diet supplemented with different concentrations 0.5, 1, and 2% for 30 days. The SP supplementations had no significant effects of SP on fish growth performance traits and lipid profiles but augmented the serum protein and globulin levels. The SP significantly improved the hepatic antioxidant status through the significant decrease of malondialdehyde (MDA) and the increases of reduced glutathione (GSH) levels and the activities of total superoxide dismutase (T.SOD), catalase (CAT) and glutathione peroxidase (GPx), especially in the SP 1% group, while glutathione S-transferase (GST) activities were significantly increased due to SP in a dose-dependent manner. The same results were obtained for the mRNA expression of CAT and GPx. Regarding the nonspecific immune status of the fish kidneys, SP, especially SP1, significantly increased interleukin-1 beta (IL-1ß) and interferon-gamma (INF-γ). The data of the present study revealed the protective effect of SP on Nile tilapia health status. Therefore, SP can be considered as a promising feed additive for Nile tilapia.

Single and Combined Effects of Clostridium butyricum and Saccharomyces cerevisiae on Growth Indices, Intestinal Health, and Immunity of Broilers.

A total of 120 1-day-old commercial Cobb chicks were used to study the effects of Clostridium butyricum (C. butyricum) and/or Saccharomyces cerevisiae (S. cerevisiae) on growth performance, intestinal health, and immune status in broilers. The experimental groups were as follows: G1; basal diet (BD), G2; basal diet (BD) plus C. butyricum preparation at 0.5 g/kg diet, G3; BD plus S. cerevisiae preparation at 0.5 g/kg diet, G4; BD plus 0.25 g/kg C. butyricum preparation plus 0.25 g/kg S. cerevisiae. Results showed that the total body weight gain, feed conversion efficiency, and protein efficiency ratio were significantly higher (p < 0.05) in the G4 group than in the other groups. The mortality percentage was reduced in the probiotic-supplemented groups. The villi height was elongated, and the villus height/crypt depth ratio was significantly increased in G2 and G4 chicks, compared to those in the control. The crypt depth was significantly decreased in all the probiotic-supplemented groups. Hemagglutination inhibition titers for Newcastle disease virus (NDV) were markedly increased in G2 and G4 chicks at 35 days of age, compared to those in G3 and control chicks. These results showed that dietary supplementation of a combined mixture of C. butyricum and S. cerevisiae in an equal ratio (G4) was more effective in improving growth performance, immune status, and gut health of broilers, compared with individual supplementation at a full dose.

Benchmarking the health of health sciences students at Kuwait University: towards a culture of health.

Health professional entry-to-practice programmes are intense, competitive and prolonged. The aims of this study were to benchmark the health of health sciences students at Kuwait University, thereby informing student health services, and to establish a base for individual student's health assessments throughout the programmes. We used a convenience sample of 176 students. Assessment included a health/wellness questionnaire (smoking, nutrition, physical activity, sleep and stress) and objective measures (resting heart rate, blood pressure, waist-to-hip ratio and random blood glucose). Students had suboptimal activity, diet, stress and sleep. Health was suboptimal based on significant proportions of students in unhealthy categories for resting heart rate, blood pressure and body composition. Health status of health sciences students at Kuwait University is not consistent with healthy health professionals in training, who should serve as role models for the public. A culture of health on campus is recommended to maximize the health of students and their capacity as health role models.
