ABSTRACT
Background The coronavirus disease 2019 (COVID-19) lockdown affected the daily habits of people around the world. Many countries have contributed to restricting its transmission by ensuing a quarantine, including Saudi Arabia, by shutting down educational facilities. Therefore, the system adapted to those changes, and people were required to stay home for work and education. Objectives This study aimed to explore the effect of the lockdown and house confinement during the COVID-19 pandemic on the important aspects of lifestyle, such as body weight, dietary habits, sleeping patterns, stress levels, screen time, and physical activity among students of Taibah University in Madinah, Saudi Arabia. Methods A cross-sectional study was carried out by a self-administered online questionnaire that was quoted from a Palestinian study. Then was translated from English to Arabic. In total, 528 Taibah University students were eligible to participate. It addressed food-related behavior (types of foods consumed) and lifestyle behavior (physical activity, sleep quality, and screen time). Results Study participants aged from 17 to 30 years, males and females. Mainly non-infected COVID-19 persons previously (54.4%). Participants showed an increase in body weight, intake of fried food, intake of sweets, sleep hours, screen time, and physical activity during lockdown. The most reported sources of stress during lockdown were staying at home all day (62.3%) and distance learning (44.9%). Conclusion The COVID-19 lockdown and the closure of universities have led to many changes in the everyday routine of university students, leading to changes in their lifestyle behaviors.
ABSTRACT
Background: Colchicine has been proposed as a cytokine storm-blocking agent for COVID-19 due to its efficacy as an anti-inflammatory drug. The findings of the studies were contentious on the role of colchicine in preventing deterioration in COVID-19 patients. We aimed to evaluate the efficacy of colchicine in COVID-19-hospitalized patients. Design: A retrospective observational cohort study was carried out at three major isolation hospitals in Alexandria (Egypt), covering multiple centers. In addition, a systematic review was conducted by searching six different databases for published studies on the utilization of colchicine in patients with COVID-19 until March 2023. The primary outcome measure was to determine whether colchicine could decrease the number of days that the patient needed supplemental oxygen. The secondary outcomes were to evaluate whether colchicine could reduce the number of hospitalization days and mortality rate in these patients. Results: Out of 515 hospitalized COVID-19 patients, 411 were included in the survival analysis. After adjusting for the patients' characteristics, patients not receiving colchicine had a shorter length of stay (median: 7.0 vs. 6.0 days) and fewer days of supplemental oxygen treatment (median: 6.0 vs. 5.0 days), p < 0.05, but there was no significant difference in mortality rate. In a subgroup analysis based on oxygen equipment at admission, patients admitted on nasal cannula/face masks who did not receive colchicine had a shorter duration on oxygen supply than those who did [Hazard Ratio (HR) = 0.76 (CI 0.59-0.97)]. Using cox-regression analysis, clarithromycin compared to azithromycin in colchicine-treated patients was associated with a higher risk of longer duration on oxygen supply [HR = 1.77 (CI 1.04-2.99)]. Furthermore, we summarized 36 published colchicine studies, including 114,878 COVID-19 patients. Conclusions: COVID-19-hospitalized patients who were given colchicine had poorer outcomes in terms of the duration of supplemental oxygen use and the length of their hospital stay. Therefore, based on these findings, the use of colchicine is not recommended for COVID-19-hospitalized adults.

Uropathogens develop biofilms on urinary catheters, resulting in persistent and chronic infections that are associated with resistance to antimicrobial therapy. Therefore, the current study was performed to control biofilm-associated urinary tract infections through assaying the anti-biofilm ability of lactic acid bacteria (LAB) against multidrug-resistant (MDR) uropathogens. Twenty LAB were obtained from pickles and fermented dairy products, and screened for their anti-biofilm and antimicrobial effects against MDR Escherichia coli U12 (ECU12). Lactobacillus plantarum Y3 (LPY3) (MT498405), showed the highest inhibitory effect and biofilm production. Pre-coating of a microtitre plate with LPY3 culture was more potent than co-incubation. Pre-coating with LPY3 culture generated a higher anti-biofilm effect with an adherence of 14.5% than cell free supernatant (CFS) (31.2%). Anti-biofilm effect of CFS was heat stable up to 100 °C with higher effect at pH 4-6. Pre-coating urinary catheter with LPY3 culture reduced the CFU/cm2 of ECU12 attached to the catheter for up to seven days. Meanwhile, CFS reduced the ECU12 CFU/cm2 for up to four days. Scanning electron microscope confirmed the reduction of ECU12 adherence to catheters after treatment with CFS. Therefore, Lactobacillus plantarum can be applied in medical devices as prophylactic agent and as a natural biointervention to treat urinary tract infections.
ABSTRACT
BACKGROUND AND AIM: Intestinal disorders represented a large proportion of abdominal emergencies in bovine practice, and their definite diagnosis was a big challenge. The study described different intestinal disorders in cattle either in the small intestine (SI) or large intestine with their sequelae and peritonitis between SI loops. MATERIALS AND METHODS: This study involved healthy (n=20) and diseased (n=40) cattle with intestinal disorders. All animals were undergoing clinical examination, laboratory analyses, and ultrasonographic examination. RESULTS: Diseased cattle had monocytic leukocytosis as well as hypoproteinemia and hypoalbuminemia. The SI ileus of either proximal (n=12) or distal (n=15), intussusception (n=3), cecal, and/or colonal dilatation (n=10) were diagnosed by ultrasound and other diagnostic tools. Duodenum intussusception was imaged in cross-section as bull's eyes lesions. Animals with SI obstructions showed complete cessation (ileus with complete obstruction) or partial reduction of the peristaltic SI movement (ileus with partial obstruction), dilated duodenum (6.5-9.9 cm), and dilated jejunum and/or ileum (4.4-6.8 cm). Ultrasonography diagnosed SI ileus, due to either intestinal obstruction or peritonitis, and detected the ileus site, either proximal or distal. Cecal/colonal dilatation was detected using ultrasonography in which SI was not imaged and the peristaltic movements were completely reduced. The recorded intestinal disorders were associated with other disorders (e.g., liver cirrhosis or peritonitis). CONCLUSION: Ultrasonography played an important role in the differential diagnosis of intestinal disorders in cattle. Peritonitis between SI loops and cecal and/or colonal dilatation was also diagnosed.
ABSTRACT
Background: Parasitic infection is one of the main problems in equidae, particularly donkeys. Aim: This study evaluated the oxidative stress in donkeys infected with Strongylus spp by determining the correlation between antioxidants levels; malondialdehyde (MDA), total antioxidant capacity (TAC), and the severity of parasitic infection. It also compared the therapeutic efficacy of piperazine citrate as an oral anthelmintic drug and Doramectin as an injectable one. Methods: The study was conducted on 40 donkeys naturally infected with Strongylus spp. These donkeys were divided into two groups (20 donkeys each) according to treatment; One group was treated with piperazine citrate (PipTG) and the other with doramectin (DoraTG). Thorough clinical examination, hematological, biochemical, and parasitological assays were performed before (Day 0) and after treatment (Days 7, 14, 21, and 28). All data were statistically analyzed by independent-sample t-test or paired t-test. Results: In both groups, mean values of MDA were significantly reduced, while those of TAC were significantly elevated after treatment on days 7, 14, 21, and 28. These significant changes were reported after treatment between PipTG and DoraTG in favor of DoraTG. Serum concentrations of MDA were significantly reduced, while those of TAC were significantly elevated for DoraTG treatment group when their values were compared with those of PipTG either on days 7, 14, 21, or 28. Significant correlations were reported in PipTG and DoraTG. Negative significant correlations were reported between fecal egg count (FEC) and each of whole blood picture indices (RBCS, Hb, and PCV), serum TAC and faecal egg count reduction percentage FECR%. A positive correlation was seen between FEC and MDA. MDA exhibited a negative correlation with both blood picture and TAC; hence, TAC was positively correlated with these blood picture indices in both PipTG and DoraTG. In PipTG, anthelmintic resistance (R) was present on days 7 and 14, while it was suspected (S) at day 21 then it was absent (N) at day 28. In DoraTG, anthelmintic resistance was suspected (S) on day 7, then it became absent (N) on days 14, 21, and 28 post therapy. Conclusion: The immunological status of the infected donkeys had greatly improved after treatment. The therapeutic efficacy of injectable doramectin was more efficient than that of oral piperazine citrate in Strongylus spp. infected donkeys.

The objective of this study was to evaluate the association between ketonemia and serum paraoxonase-1 (PON1), malondialdehyde (MDA), and other blood components in tail and mammary veins of dairy cows. Forty-two Holstein dairy cows with decreased feed intake were divided into HIGH (≥ 1.2 mM; n = 31) and LOW (< 1.2 mM; n = 11) groups based on the ß-hydroxybutyrate concentration in plasma collected from the tail vein. The HIGH group had a significantly greater plasma non-esterified fatty acid (NEFA) concentration, but significantly lower serum PON1 activity and phospholipid concentration, and a tendency to have a lower cholesterol ester concentration than the LOW group. Serum PON1 activity was not correlated with the MDA concentration but was positively correlated with serum concentrations of cholesterol esters and phospholipids, and negatively correlated with the plasma NEFA concentration. These results suggest that serum PON1 activity is reduced by hyperketonemia and the relevance of PON1 to MDA seems to not be direct, though it is involved.
L'objectif de la présente étude était d'évaluer l'association entre l'acétonémie et la paraoxonase-1 (PON1), le malondialdéhyde (MDA), et d'autres composés du sang dans les veines caudale et mammaire de vaches laitières. Quarante-deux vaches laitières de race Holstein présentant une diminution de l'ingestion d'aliments furent divisées en groupes ÉLEVÉ (≥ 1,2 mM; n = 31) et BAS (< 1,2 mM; n = 11) basés sur la concentration de ß-hydroxybutyrate de plasma prélevé de la veine caudale. Le groupe ÉLEVÉ avait une concentration plasmatique significativement plus grande d'acides gras non-estérifiés (NEFA), mais le sérum présentait une activité PON1 et une concentration de phospholipides significativement réduite, et une tendance à avoir une concentration d'esters de cholestérol plus faible que le groupe BAS. L'activité de PON1 sérique n'était pas corrélée avec la concentration de MDA mais était corrélée positivement avec les concentrations sériques d'esters de cholestérol et de phospholipides, et corrélée négativement avec la concentration plasmatique de NEFA. Ces résultats suggèrent que l'activité de PON1 sérique est réduite par l'hypercétonémie et la pertinence de PON1 envers MDA ne semble pas être directe, bien qu'elle semble impliquée.(Traduit par Docteur Serge Messier).

BACKGROUND: Schizophrenia (SZ) is associated with cognitive impairment that contributes to disability, but the cognitive dysfunction is relatively refractory to pharmacologic intervention. Though Valproate augmentation is reported to improve psychopathology among patients with SZ, its effects on cognitive functions have not been investigated systematically. METHODS: Using a randomized double blind placebo controlled design, the effects of Valproate or placebo as adjuncts to risperidone (RISP) treatment were evaluated among patients with early course SZ (Nâ¯=â¯109). Domains of cognitive function, estimated using the Arabic version of the Penn Computerized Neurocognitive Battery, were the prime outcomes. Clinical severity and social function were secondary outcomes. We also explored the effects of valproate treatment on serological responses to Toxoplama Gondii (TOXO), a putative risk factor for cognitive dysfunction in SZ. RESULTS: There were no significant differences between Valproate and placebo (PLA) treated groups with respect to changes in cognitive functions, positive or negative symptom scores or daily function scores at the beginning and end of the study. No significant Valproate/PLA differences were noted on TOXO serostatus or TOXO-related cognitive dysfunction. CONCLUSION: Valproate treatment may not be beneficial for cognitive dysfunction in SZ or for TOXO infection.

The aim of this study was to characterize peripartum metabolic profiles, including the insulin sensitivity index, in cows diagnosed with subclinical ketosis (SCK) in the early stage of lactation. Cows that calved from January 2011 through December 2014 on a dairy farm with alarm level prevalence of SCK in Hokkaido, Japan (n = 175) were used. Blood and body condition scores (BCS) were obtained at regular health examinations in 2 consecutive periods, the first between 14 and 2 d before parturition, and the second between 3 and 14 d after parturition. Animals were divided into 3 groups at postpartum sampling: an SCK group with 35 multiparous and 15 primiparous cows having ß-hydroxybutyrate (BHBA) concentrations ≥ 1.2 mM without clinical signs, a disease group of 36 multiparous and 9 primiparous cows that received treatment between parturition and postpartum sampling, and a control group consisting of 49 multiparous and 31 primiparous cows with BHBA concentrations < 1.2 mM. The prepartum revised quantitative insulin sensitivity check index was significantly lower in the multiparous SCK and disease groups than in the control group, demonstrating decreased insulin sensitivity in these cows, but not in primiparous cows. The prepartum BCS was significantly higher only in the multiparous SCK and disease groups. The prepartum apolipoprotein B-100 (ApoB-100) concentration was significantly decreased in the multiparous disease group, suggesting hepatic lipidosis. Conversely, primiparous cows had a higher prepartum ApoB-100 concentration. Prepartum decreased insulin sensitivity in the multiparous SCK and disease groups was considered to facilitate progression to SCK after calving.
L'objectif de la présente étude était de caractériser les profils métaboliques péri-partum, incluant l'index de sensibilité à l'insuline, chez des vaches avec un diagnostic d'acétonémie subclinique (ASC) tôt en début de lactation. Les vaches qui ont mis bas entre janvier 2011 et décembre 2014 sur une ferme laitière avec une prévalence d'ASC à un degré d'alarme à Hokkaido, Japon (n = 175) ont été utilisées. Du sang et les pointages de condition corporelle (PCC) ont été obtenus au moment d'examens de santé réguliers lors de deux périodes consécutives, la première entre 14 et 2 j avant la parturition, et la seconde entre 3 et 14 j après la parturition. Les animaux ont été divisés en trois groupes lors de l'échantillonnage post-partum : un groupe ASC avec 35 vaches pluripares et 15 vaches primipares ayant des concentrations de ß-hydroxybutyrate (BHBA) ≥ 1,2 mM sans signe clinique, un groupe malade avec 36 vaches pluripares et 9 vaches primipares qui ont reçu un traitement entre le moment de la parturition et la prise d'échantillon post-partum, et un groupe témoin composé de 49 vaches multipares et 31 vaches primipares avec des concentrations de BHA < 1,2 mM. L'indice quantitatif de sensibilité à l'insuline révisé pré-partum était significativement plus bas dans les groupes de vaches multipares ASC et vaches malades que dans le groupe témoin, démontrant ainsi une diminution de la sensibilité à l'insuline chez ces vaches mais pas chez les vaches primipares. L'ASC pré-partum était significativement plus élevé seulement dans les groupes ASC multipares et malade. La concentration pré-partum d'apolipoprotéine B-100 (ApoB-100) était significativement diminuée chez les vaches multipares du groupe malade, suggérant une lipidose hépatique. Inversement, les vaches primipares avaient une concentration plus élevée d'ApoB-100. La sensibilité à l'insuline diminuée en pré-partum chez les vaches ASC multipares et vaches malades était considérée pour faciliter la progression d'ASC à la suite de la mise-bas.(Traduit par Docteur Serge Messier).

BACKGROUND AND AIM: Increasing prevalence of neonatal sepsis in recent years catch attention to early prevention and management. Vitamin D receptor (VDR) polymorphism can modulate VDR expression level that greatly influences immunity and susceptibility to microbial infections. We aimed to investigate the association of VDR polymorphism at FokI, rs2228570 T/C, and TaqI, rs731236 C/T gene with serum 25-hydroxyvitamin D level and risk of neonatal sepsis. METHODS: This work carried on 160 subjects classified into 80 cases (40 mothers and their 40 septic neonates) and 80 healthy controls (40 volunteer mothers and their 40 healthy neonates). Genotyping of VDR polymorphisms were assayed by real-time PCR and serum 25-hydroxyvitamin D level and hs-CRP were measured by ELISA. RESULTS: Vitamin D deficiency was observed in mothers of cases compared with healthy ones (pâ¯=â¯<0.001) and in septic neonates versus healthy ones (pâ¯=â¯<0.001). Septic neonates had much higher VDR FokI TT genotype (pâ¯=â¯0.014) and T allele (pâ¯=â¯0.003) versus healthy ones. TT genotype and T allele could increase the risk of sepsis with OR 95% CI [4.804 (1.4-16.4)] and [2.786 (1.4-5.7)] respectively while VDR TaqI showed no association with sepsis. There was a strong LD between FokI and TaqI in sepsis cases. In sepsis, T/T genotype at FokI had significantly lower vitamin D (pâ¯=â¯<0.001). CONCLUSION: Vitamin D deficiency in mothers/neonates is a risk factor for neonatal sepsis. VDR FokI T allele had lower 25-hydroxyvitamin D level that may predispose to sepsis hazards.

Traumatic pericarditis (TP) remains a serious problem facing bovine producers; particularly in the developing countries; causing severe economic losses. This study was carried out on 47 buffaloes including; control buffaloes (n = 20) and buffaloes with TP (n = 27) at Assiut governorate, Egypt. All animals were subjected to thorough clinical examination, whole blood profiling, blood serum biochemical assays, and radiographic and ultrasonographic examinations. The recorded ultrasonographic findings included; the contractility, contour and shape of the reticulum, shape and size of the heart and spleen involvement. All data were statistically analysed. Buffaloes with TP showed lymphocytic leucocytosis, increase in serum activities of AST, hyperproteinaemia, hypoalbuminaemia and hyperglobulinaemia. Radio-opaque metal foreign bodies, cardiomegaly and loss of the normal cardiac shape and contour were the most common radiographic findings in the diseased buffaloes. Ultrasonographically, the diseased buffaloes showed either acute pericarditis (n = 10) or chronic suppurative pericarditis (n = 17). Complete cessation of reticular contractions (0/3 min) and displacement of the reticulum from the diaphragm by a distance about 2.6-4.5 cm were the most common ultrasonographic findings of both types of pericarditis. In addition, the reticulum had uneven contour and the heart showed characteristic changes in its size, shape and contractility that was either accelerated or reduced. Reticular abscesses and peritoneal effusions were also imaged in all diseased buffaloes. In acute TP; the affected heart was enlarged with strong and clear cardiac contractions. Accumulation of hypoechoic fluids interspersed with echogenic deposits of fibrin within heart tissue and pericardium was observed. In chronic suppurative pericarditis, cardiomegaly, thickening of the cardiac wall and loss of the characteristic recognisable heart shape were the common ultrasonographic findings. Accumulation of hypoechoic fluids (usually pus) interspersing with echogenic deposits of fibrin within the pericardium, ventricles, atria and valves was also observed. In conclusion, ultrasonography with the aids of other diagnostic tools such as clinical findings, laboratory analysis and radiography has a high efficacy in evaluation of diseased buffaloes with TP.
ABSTRACT
Children with end-stage renal disease (ESRD) suffer from dyslipidemia and hyperuricemia that might play a causal role in the progression of cardiovascular disease (CVD). The aim of the study is to assess the effects of Vitamin C supplementation on uric acid, ascorbic acid, and serum lipid levels among children on hemodialysis (HD). This prospective study was conducted in the pediatric nephrology unit at Menoufia University Hospital. The study included a total of 60 children with ESRD on maintenance HD therapy. They were divided into two groups: Group I (supplemented group, n = 30) received intravenous Vitamin C supplementation and Group II (control, n = 30) received placebo (intravenous saline) for three months. The results are shown as a mean ± standard deviation. Statistical evaluation was performed by SPSS software (version 11.5) using paired t-test. After supplementation with Vitamin C, the serum Vitamin C and high-density lipoprotein levels increased significantly with a significant reduction in the levels of serum uric acid, cholesterol, low-density lipoproteins, and triglyceride at the end of the study period. No significant changes were observed in the control group. Vitamin C can serve as a useful urate lowering medicine in HD patients to avoid complications of hyperuricemia. Furthermore, it had favorable effects on the lipid profile. This improvement can be considered as a preventive strategy in the progression of CVD in HD patients. Vitamin C supplementation improves ascorbic acid deficiency in these patients.

BACKGROUND AND OBJECTIVES: Impulsive behavior has been repeatedly identified as a major problem in schizophrenia. Our objective was to examine the possible demographical and clinical correlates for impulsive behavior in patients with schizophrenia. METHODS: Fifty-eight patients with schizophrenia and Seventy-seven healthy controls were recruited. Sociodemographic data were collected and they were subjected to the Barratt Impulsiveness Scale (BIS), Positive and Negative Syndrome scale (PANSS), and Trauma Assessment for Adults-Brief Revised Version (TAA). RESULTS: Correlations between impulsive behavior and psychosocial variables were examined. A significant association between level of impulsive behavior and severity of psychopathological symptoms was observed (P=0.0001). Young age (P=0.001), male patients (P=0.0001) and those with history of childhood sexual or physical abuse (P=0.0001), were more impulsive. Linear regression (step wise) analysis model showed that male sex (P=0.001), positive symptoms (P=0.006), and childhood physical abuse (P=0.001) were significant associations. CONCLUSION: Male gender, positive symptoms as well as history of physical and sexual abuse before 18 years of age are important predictors for high levels of impulsive behavior in schizophrenia patients.

OBJECTIVES: To develop Arabic versions of English language questionnaires to estimate morningness/eveningness and sleep variables. METHODS: We translated the Composite scale of morningness (CSM) and the sleep timing questionnaire (STQ) [with added siesta questions] into Arabic; the Arabic versions were then back translated. The revised Arabic and the original English versions were next administered to bi-lingual Egyptians using a crossover design (n=25). The Arabic versions of both scales were subsequently administered to an independent Egyptian sample (n=79) and the siesta variables examined in relation to the CSM. RESULTS: Satisfactory correlations were present between the English and Arabic versions for total CSM scores (Spearman's ρ=0.90, p<0.001). All but one of the STQ variables were significantly correlated (Spearman's ρ=0.45-0.88, p≤0.05). In the Arabic version, the frequency of siesta naps per week was significantly correlated with the total CSM score, with evening types taking more naps (Spearman's ρ=-0.23, p≤0.05). CONCLUSIONS: Arabic versions of the STQ and CSM have been developed in Egypt, and are freely available. They can be used for behavioral research related to sleep and circadian function and can be adapted for use in other Arab speaking populations.

OBJECTIVE: To evaluate reproduction among patients with bipolar I disorder (BP1) or schizophrenia (SZ) in Egypt. METHODS: BP1 patients (n=113) were compared with community based, demographically balanced controls (n=124) and SZ patients (n=79, DSM-IV). All participants were evaluated using structured interviews and corroborative data were obtained from relatives. Standard indices of procreation were included in multivariate analyses that incorporated key demographic variables. RESULTS: Control individuals were significantly more likely to have children than BP1 or SZ patients (controls 46.8%, BP1 15.9%, SZ 17.7%), but the BP1-SZ differences were non-significant. The average number of children for BP1 patients (0.37±0.9) and SZ patients (0.38±0.9) was significantly lower than for controls (1.04±1.48) (BP1 vs controls, p<0.001; SZ vs controls, p<0.001). The frequency of marriages among BP1 patients was nominally higher than the SZ group, but was significantly lower than controls (BP1: 31.9% SZ: 27.8% control: 57.3%). Even among married individuals, BP1 (but not SZ) patients were childless more often than controls (p=0.001). The marital fertility, i.e., the average number of children among patients with conjugal relationships for controls (1.8±1.57) was significantly higher than BP1 patients (1.14±1.31, p=0.02), but not significantly different from SZ patients (1.36±1.32, p=0.2). CONCLUSION: Selected reproductive measures are significantly and substantially reduced among Egyptian BP1 patients. The reproductive indices are similar among BP1 and SZ patients, suggesting a role for general illness related variables. Regardless of the cause/s, the impairment constitutes important, under-investigated disability.
ABSTRACT
We have recently found that consanguinity is a risk factor for bipolar I disorder (BP1) and schizophrenia (SZ) in Egypt. Inbreeding has been associated with increased cellular stress and impaired physiological function in plants and animals. Previous studies have reported that telomere length (TL), an index of oxidative stress and cellular senescence is significantly reduced among patients with SZ or mood disorders compared with control individuals. Hence we evaluated TL as a possible mediator of the observed association between consanguinity and BP1/SZ risk. Patients with BP1 (n=108), or SZ (n=60) were compared with screened adult controls in separate experiments. TL was estimated using a quantitative PCR (qPCR) based assay. The inbreeding coefficient/consanguinity rate was estimated in two ways: using 64 DNA polymorphisms ('DNA-based' rate); and from family history data ('self report'). Significant correlation between TL and DNA based inbreeding was not observed overall, though suggestive trends were present among the SZ cases. No significant case-control differences in TL were found after controlling for demographic variables. In conclusion, reduced TL may not explain a significant proportion of observed associations between consanguinity and risk for BP1/SZ.
