RESUMO
BACKGROUND: Although swallowing disorders can impact individuals of any age, some are unique to the elderly, and others are frequent. Some disorders, such as achalasia, are diagnosed by esophageal manometry studies, which assess lower esophageal sphincter (LES) pressure and relaxation, peristalsis in the esophageal body, and contraction wave characteristics. This research aimed to evaluate esophageal motility dysfunction in symptomatic patients and its relation to age. METHODS: Conventional esophageal manometry was performed on 385 symptomatic patients who were divided into two groups; Group A (age < 65 years old) and Group B (age ≥ 65 years). The geriatric assessment for Group B included cognitive, functional, and clinical frailty scales (CFS). Additionally, a nutritional assessment was done for all patients. RESULTS: About one-third of the patients (33%) had achalasia, in which manometric results were significantly higher in Group B (43.4%) than in Group A (28.7%) (P = 0.016). The resting lower esophageal sphincter (LES) pressure, as determined by manometry examination, was significantly lower in Group A than in Group B. In contrast, complete LES relaxation percentage and normal esophageal body peristalsis were significantly higher in Group A than in Group B. Patients who exhibited evidence of achalasia in the manometric study had a significantly increased risk of established malnutrition and functional impairment. CONCLUSIONS: Achalasia is a prevalent cause of dysphagia in elderly patients, placing them at risk of malnutrition and functional impairment. Thus, a multidisciplinary approach is vital when providing care for this population.

COVID-19 pandemic continues to be a global health crisis. The gut microbiome critically affects the immune system, and some respiratory infections are associated with changes in the gut microbiome; here, we evaluated the role of nutritional and lifestyle habits that modulate gut microbiota on COVID-19 outcomes in a longitudinal cohort study that included 200 patients infected with COVID-19. Of these, 122 cases were mild and seventy-eight were moderate, according to WHO classification. After detailed explanation by a consultant in clinical nutrition, participants responded to a written questionnaire on daily sugar, prebiotic intake in food, sleeping hours, exercise duration and antibiotic prescription, during the past 1 year before infection. Daily consumption of prebiotic-containing foods, less sugar, regular exercise, adequate sleep and fewer antibiotic prescriptions led to a milder disease and rapid virus clearance. Additionally, data on these factors were compiled into a single score, the ESSAP score (Exercise, Sugar consumption, Sleeping hours, Antibiotics taken, and Prebiotics consumption; 0-11 points), median ESSAP score was 5 for both mild and moderate cases; however, the range was 4-8 in mild cases, but 1-6 in moderate (P = 0·001, OR: 4·2, 95 % CI 1·9, 9·1); our results showed a negative correlation between regular consumption of yogurt containing probiotics and disease severity (P = 0·007, OR: 1·6, 95 % CI 1·1, 2·1). Mild COVID-19 disease was associated with 10-20 min of daily exercise (P = 0·016), sleeping at least 8 h daily, prescribed antibiotics less than 5 times per year (P = 0·077) and ate plenty of prebiotic-containing food.

INTRODUCTION: Continuous positive airway pressure (CPAP) is the most effective treatment for obstructive sleep apnea (OSA). Adequate compliance with the use of CPAP is cardinal to achieve cardiovascular, metabolic and neuropsychological benefits of treatment. AIM: Assess the factors affecting compliance to the CPAP treatment and analyze the long term acceptance. METHODS: Retrospective study on 130 patients treated by CPAP for OSA in the department of pulmonology between 2005 and 2014. Long term acceptance was analysis using the method of survival analysis. RESULTS: These patients are characterized by a mean age of 55.4± 10.2 years; main comorbidities were found hypertension (47%), diabetes (25.5%) and COPD (11%). Median baseline apnea-hypopnea index was (AHI), 56 ± 19,5/h. One hundred thirty patients were enrolled with a mean follow up of 75 ± 34 months, 42 patients stopped their treatment, 21% of them in the first 6 months. In compliant patients, the median value of daily CPAP use was 5, 5 ± 2 hours. Kaplan Meier analysis showed that 96% of patients were still using CPAP at 12 months, 69,4% at 5 years and 64,1% at 10 years. Chronic Obstructive Pulmonary Disease was identified as a predictor factor of long term CPAP use. Non observing patients had a higher probability to stop the use of CPAP compared to adherent patients Conclusion: the treatment of OSA with CPAP is generally well accepted in the long term. Treatment dropouts are more common among non-adherent patients justify regular monitoring in the first months of treatment.

BACKGROUND: Tunisian pulmonary functional laboratories accept the default settings for reference equations (European Respiratory Society/European Community for Steel and Coal (ERS/ECSC1983) offered by the manufacturer even though adult Tunisian reference equations (Tunisian1995) are available. OBJECTIVE: To compare the spirometric profile of Tunisian subjects, according to the two reference equations. POPULATION AND METHODS: Spirometric data were recorded from 1192 consecutive spirometry procedures in adults aged 18-60 years. Reference values and lower limits of normality (LLN) were calculated using the two reference equations. Applied definitions: large airway obstructive ventilatory defect (LAOVD): ratio between the 1st second expiratory volume and forced vital capacity (FEV1/FVC) < LLN. Small AOVD (SAOVD): FEV1/FVC > LLN and FVC > LLN and maximal midexpiratory flow < LLN. Tendency through a restrictive ventilatory defect (TRVD): FEV1 and FVC < LLN. The spirometric profile, according the two reference equations, was determined. RESULTS: Using Tunisian1995 reference equations, 34%, 7%, 37% and 19% of spirometry records were interpreted as normal, and as having, LAOVD, SAOVD and TRVD, respectively. Using ERS/ECSC1983 reference equations, 85%, 3%, 9% and 2% of spirometry records were interpreted as normal, and as having, LAOVD, SAOVD and TRVD, respectively. Using the ERS/ECSC1983 reference equations, misclassification was worse for LAOVD, for SAOVD and for TRVD, respectively, 68%, 94% and 89%. CONCLUSION: Our results showed that the use of the old Caucasian reference equations resulted in misinterpretation of spirometry data in a significant proportion of subjects. This could result in inappropriate diagnosis and/or management.

We analyzed highly pathogenic avian influenza A(H5N1) viruses isolated from humans infected in Egypt during 2007-2011. All analyzed viruses evolved from the lineage of subtype H5N1 viruses introduced into Egypt in 2006; we found minimal evidence of reassortment and no exotic introductions. The hemagglutinin genes of the viruses from 2011 formed a monophyletic group within clade 2.2.1 that also included human viruses from 2009 and 2010 and contemporary viruses from poultry; this finding is consistent with zoonotic transmission. Although molecular markers suggestive of decreased susceptibility to antiviral drugs were detected sporadically in the neuraminidase and matrix 2 proteins, functional neuraminidase inhibition assays did not identify resistant viruses. No other mutations suggesting a change in the threat to public health were detected in the viral proteomes. However, a comparison of representative subtype H5N1 viruses from 2011 with older subtype H5N1 viruses from Egypt revealed substantial antigenic drift.

Introduction: The global prevalence of Non-alcoholic fatty liver disease (NAFLD) is about 25% worldwide making it an actual health disaster. This study aimed to assess non-alcoholic fatty liver disease (NAFLD)-related knowledge in a sample of Egyptians. Materials and methods: This exploratory cross-sectional study was conducted on 3,124 individuals using 2000 online and 1,124 printed questionnaire forms. These questionnaires, covering sociodemographic characteristics and fatty liver-related knowledge, comprised 30 items. These items include ten questions on definition, symptoms, and complications: 14 about risk factors, and six about prevention and therapy. The data were analyzed using SPSS. Categorical variables were expressed in proportions and percentages. Chi-square and Fisher's exact tests were applied as appropriate. For quantitative variables, the t-test, Mann-Whitney U test, Kruskal-Wallis test, and ANOVA test were used for comparisons. Results: A total of 3,124 respondents were enrolled in the current study. More than half (57%) were females, and 25% ranged in age from 18 to 29. 10.8% of the participants believed that fatty liver patients were asymptomatic, and 34% knew that fatty liver disease was caused by fat accumulation. Regarding predisposing factors, hypercholesterolemia, increased fat in the diet, and obesity had the highest proportion of accurate responses (60, 54, and 46.6%, respectively). On the other hand, 89.3% believed it could be prevented, and 81.4% of the respondents knew that weight reduction could prevent the condition. All respondents (100%) stated wrongly that it was a familial disease related to aging, and most participants (97.3%) did not believe that fatty liver could be treated. Females demonstrated a significantly higher score in preventive measures, while the employed participants scored significantly higher in general knowledge of fatty liver, risk factors, and preventive measures. Conclusion: Despite the increasing NAFLD prevalence, the current study indicated that Egyptians had fair to moderate knowledge about fatty liver and its risk factors, preventive measures, and therapy. However, a false belief was documented by all respondents that it is a disease that runs in families and occurs only in old age. A fundamental shift in healthcare management with a prioritization of prevention, proactive measures, and early detection of NAFLD should be emphasized.

BACKGROUND: Nutritional status and physical activity are essential to maintain a strong immune system. No definite pharmacological strategies for Coronavirus disease 2019 treatment are presently available, so natural enhancement of the immune system is in need. Our goal was to assess the correlation of healthy diet and physical activity on COVID-19 disease outcome. METHODS: This cohort study was conducted on 68 adult patients who contracted mild (38) or moderate [30] cases of COVID-19, recruited via a convenience sampling technique from the outpatient clinic, Kasr Al-Aini Faculty of Medicine, Cairo University Hospital. Patients' Healthy Eating Index (HEI) and degree of physical activity as measured by the Global Physical Activity Questionnaire were evaluated and linked with several inflammatory markers. RESULTS: Most of patients with mild COVID-19 patients (92.1%) were physically active, compared to only 50% of moderate COVID-19. The total Metabolic Equivalent Task-min/week was positively correlated with the lymphocyte percentage. The median total HEI score was significantly higher in the patients with mild COVID-19 than with moderate COVID. Significant positive correlations observed among the lymphocyte count and total HEI-2015. There was approximately a 64% reduction in the probability of acquiring moderate COVID-19 illness for each unit rise in The HEI. CONCLUSION: Healthier nutrition and Physical activity correlated with reduced COVID-19 disease severity. TRIAL REGISTRATION: The study was registered on clinical trial.gov maintained by the US National Library of Medicine (CinicalTrials.gov identifier = NCT04447144; https://clinicaltrials.gov/ ) (25/06/2020).
RESUMO
Background: Risk factors for the severity of occupational asthma (OA) are often attributed to occupational exposure. However, some recent epidemiological data suggest a link with obesity. The study aimed to analyze the relationship between obesity and the severity of (OA) assessed by non-specific bronchial provocation. Materials and Methods: We conducted an epidemiological descriptive retrospective study including patients who were referred to the Occupational Medicine Department of Farhat Hached University Hospital of Sousse, for (OA) and who have completed a non-specific bronchoprovocation test to metacholine. Results: Our population consisted of 131 cases of (OA) with a female predominance. The average BMI was 27.34 ±5.30 kg. Obesity was observed in 29.8% of cases. The non-specific metacholine bronchial provocation test revealed an average dose of PD20 at 750.4 ±656.3 µg. Severe (OA) was observed in (35.1%). After univariate analysis, obesity in asthmatics had a significant association with age (p<0.001), marital status (p=0.005), average professional seniority (p<0.001), the evolution of complaints (p=0.035) and abnormal initial spirometry (p=0.044). As for the severity of (OA), the univariate analytical study did not show a significant link with obesity (p=0.68). Conclusion: The association between obesity and OA is not an easy task and should be made using more accurate tools to measure body fat percentage. The preventive role of the occupational physician is essential in factories in order to make more prudent decisions when employing workers with a high BMI in high-risk occupations. Hence the importance of regular monitoring of weight in workers exposed to asthmatics during periodic examinations.
RESUMO
BACKGROUND & AIMS: Coronavirus disease - 2019 (COVID-19) is a major pandemic that causes high morbidity and mortality rates. AIM OF THIS STUDY: to detect the relations between many risk factors, ACE-2, MCP-1, Micro RNA 146 gene expression, and COVID-19 infection and disease severity. METHODS: This study was carried out on 165 cases of COVID-19 and 138 controls. ACE2 and MCP1 levels were measured in COVID-19 cases and control by ELISA and micro-RNA-146 expression by PCR. RESULTS: We found an increased blood level of ACE2 and MCP1 in COVID- 19 patients than in healthy persons and a significant down-regulation of micro-RNA 146 gene expression in cases than in controls. There was a significant correlation between increased blood level of ACE2, regulation of micro-RNA 146 gene expression and severity of lung affection, a significant correlation was found between increased blood level of MCP1 and thrombosis in COVID-19 patients. Neurological complications were significantly correlated with more viral load, more ACE2 blood level, and down regulation of micro RNA146 expression. CONCLUSION: High viral load, increased blood level of ACE2, and down-regulation of micro-RNA 146 expression are associated with more severe lung injury and the presence of neurologic complications like convulsions and coma in COVID-19 Egyptian patients.

INTRODUCTION: GST non-functional genotypes can lead to the accumulation of toxic intermediates, resulting in liver damage and increasing susceptibility to ATDH. AIM: To investigate the impact of GST Mu (GSTM1), GST Theta (GSTT1) null genotypes, and GST Pi (GSTP1; adenosine (A) > guanine (G), rs1695) variant allele on the development of ATDH in Tunisian patients treated with anti-tuberculosis therapy. METHODS: This was a case-control study including patients receiving anti-tuberculosis regimen. Cases (n = 23) were tuberculosis patients presenting ATDH during two months of anti-tuberculosis drug therapy. Controls (n = 30) were patients treated for tuberculosis, but presenting no ATDH. Genotyping was performed using a polymerase chain reaction-restriction fragment length polymorphism. RESULTS: No statistically significant association was observed between GSTM1 and GSTT1 homozygous null genotypes, and the risk of ATDH. A statistically significant association between GSTM1 and GSTT1 double null genotypes, and the risk of ATDH was found (p = 0.033) between cases and controls. For GSTP1, the distribution of GG homozygous mutant genotype was significantly associated with ATDH compared with the wild and the transition A to G (AA + AG) genotypes. CONCLUSION: Double deletion of GSTM1 and GSTT1 may predispose to ATDH in a Tunisian population. Moreover, GSTP1 rs1695 (A > G) genotyping can predict susceptibility to developing ATDH.

OBJECTIF: Etudier la valeur pronostique de l'évaluation de la qualité de vie (QDV) pour la survie chez les patients Tunisiens atteints du CDP. Méthodes: Une étude prospective de cohorte a été réalisée entre Janvier 2018 et Juin 2019. Le Performance status (PS), QoL questionnairecore30 (QLQ-C30), QoL questionnaire-Lung Cancer 13 (QLQ-LC13) et European QoL-5 dimensions-3level version questionnaire (EQ-5D-3L) ont été utilisés pour l'évaluation de la QDV. Les patients ont été divisés en 2 groupes selon le score global QLQ-C30, un Déficit Cliniquement Significatif (DCS) a été considéré si le score était ≤50. Les modèles de régression de Cox et Stepwise ont été réalisée pour évaluer la signification pronostique de la QDV. La survie globale (SG) a été calculée à l'aide de la méthode de Kaplan-Meier. Le test du log-rank a été utilisé pour comparer les courbes de survie. Le seuil de valeur de p pour la signification statistique était de 0,05. Résultats: Cent patients ont été inclus. La médiane de SG des patients avec DCS en qualité de vie était significativement inférieure à celle des patients sans déficit : respectivement 365 jours versus 467 jours, (test du log-rank, p = 0,036). De même pour la médiane de survie sans progression : 122 jours versus 326 jours pour ceux qui n'ont pas signalé de différence significative en QDV (test du log-rank, p = 0,05). L'analyse de régression multivariée stepwise a montré que le score global de QDV (QLQ-C30) était un facteur prédictif significatif de SG (coefficient estimate (CE)= 0.336, p=0.005), ainsi que le stade IV (CE=-0.193, p=0.033) et la progression tumorale (CE =-0.238, p=0.047). CONCLUSION: La QDV était un facteur prédictif de survie dans notre cohorte de patients atteints de CDP. Cela devrait recommander une intervention active en soins palliatifs précoces pour les patients présentant un déficit significatif en QDV.

INTRODUCTION: Duration of antibiotic treatment in acute exacerbation of COPD (AECOPD) is most commonly based on expert opinion. Typical administration periods range from 5 to 7 days. A 2-day course with levofloxacin was not previously assessed. We performed a randomized clinical trial to evaluate the efficacy of 2-day versus 7-day treatment with levofloxacin in patients with AECOPD. METHODS AND ANALYSIS: Patients with AECOPD were randomized to receive levofloxacin for 2 days and 5 days placebo (n = 155) or levofloxacin for 7 days (n = 155). All patients received a common dose of intravenous prednisone daily for 5 days. The primary outcome measure was cure rate, and secondary outcomes included need for additional antibiotics, ICU admission rate, re-exacerbation rate, death rate, and exacerbation-free interval (EFI) within 1-year follow-up. The study protocol has been prepared in accordance with the revised Helsinki Declaration for Biomedical Research Involving Human Subjects and Guidelines for Good Clinical Practice. The study was approved by ethics committees of all participating centers prior to implementation (Monastir and Sousse Universities). RESULTS: 310 patients were randomized to receive 2-day course of levofloxacin (n = 155) or 7-day course (n = 155). Cure rate was 79.3% (n = 123) and 74.2% (n = 115), respectively, in 2-day and 7-day groups [OR 1.3; 95% CI 0.78-2.2 (p = 0.28)]. Need for additional antibiotics rate was 3.2% and 1.9% in the 2-day group and 7-day group, respectively; (p = 0.43). ICU admission rate was not significantly different between both groups. One-year re-exacerbation rate was 34.8% (n = 54) in 2-day group versus 29% (n = 45) in 7-day group (p = 0.19); the EFI was 121 days (interquartile range, 99-149) versus 110 days (interquartile range, 89-132) in 2-day and 7-day treatment groups, respectively; (p = 0.73). One-year death rate was not significantly different between the 2 groups, 5.2% versus 7.1% in the 2-day group and 7-day group, respectively; (p = 0.26). No difference in adverse effects was detected. CONCLUSION: Levofloxacin once daily for 2 days is not inferior to 7 days with respect to cure rate, need for additional antibiotics and hospital readmission in AECOPD. Our findings would improve patient compliance and reduce the incidence of bacterial resistance and adverse effects.

Background and Aims: Currently, liver biopsy is the gold standard method for diagnosis of non-alcoholic fatty liver severity. It is critical to develop non-invasive diagnostic method to diagnose nonalcoholic fatty liver rather than invasive techniques. Our case-control study was to address the value of circulating miRNA-122 and serum pro-neurotensin as a potential non-invasive biomarker for the diagnosis of non-alcoholic fatty acid diseases. Methods: Clinical assessment, laboratory investigations, and anthropometric measurements were reported for 157 patients with proven NAFLD. Apparently, healthy participants (n=100) were enrolled as a control group. Serum samples were tested for micro-RNAs-122 and pro-neurotensin. Results: Compared with the control subjects, both mi-RNA-122 and serum proneurotensin levels were increased in NAFLD (p<0.001) and at a cut-off ≥6.83, mi-RNA-122 had 51.0% sensitivity, 70.0% specificity to differentiate NAFLD from healthy controls, while serum proneurotensin had 80.0% sensitivity and 80.0% specificity at a cutoff ≥108. Conclusion: The circulating pro-neurotensin might be used as a novel biomarker for diagnosis of patients with NAFLD, wherefore the integration of a circulating mi-RNA-122 and serum pro-neurotensin could be beneficial to diagnose NAFLD cases. Large-scale studies are needed to investigate the possible role of mi-RNA-122 and pro-neurotensin in the development, progression, and prognosis of NAFLD and NASH.
RESUMO
Introduction of microbial contaminations in the dairy value chain starts at the farm level and the initial microbial composition may severely affect the production of high-quality dairy products. Therefore, understanding the farm-to-farm variation and longitudinal shifts in the composition of the bulk tank milk microbiota is fundamental to increase the quality and reduce the spoilage and waste of milk and dairy products. In this study, we performed a double experiment to study long- and short-term longitudinal shifts in microbial composition using 16S rRNA gene amplicon sequencing. We analyzed milk from 37 farms, that had also been investigated two years earlier, to understand the stability and overall microbial changes over a longer time span. In addition, we sampled bulk tank milk from five farms every 1-2 weeks for up to 7 months to observe short-term changes in microbial composition. We demonstrated that a persistent and farm-specific microbiota is found in bulk tank milk and that changes in composition within the same farm are mostly driven by bacterial genera associated with mastitis (e.g., Staphylococcus and Streptococcus). On a long-term, we detected that major shift in milk microbiota were not correlated with farm settings, such as milking system, number of cows and quality of the milk but other factors, such as weather and feeding, may have had a greater impact on the main shifts in composition of the bulk tank milk microbiota. Our results provide new information regarding the ecology of raw milk microbiota at the farm level.
RESUMO
BACKGROUND: The novel coronavirus disease 2019 presents an urgent threat to global health. As the epidemic grows, prognosis prediction is essential for monitoring risky patient. It is thus important to consider gastrointestinal manifestations and the duration of symptoms as predictors of prognosis. Our aim was to determine the correlation of gastrointestinal symptoms and laboratory markers with disease outcomes and whether symptom duration varies substantially between patients. We also undertook this study to determine the optimal time to predict COVID-19 outcome. PATIENTS AND METHODS: A total of 190 patients with polymerase chain reaction-confirmed COVID-19 were followed up until recovery. We proposed a correlation between gastrointestinal symptoms and disease severity (based on clinical data, and diagnostic investigations) to estimate the duration of symptoms as a predictor of COVID-19 prognosis. RESULTS: The prevalence of gastrointestinal symptoms was 49.5%, consisting mainly of diarrhea in 27.9% of patients. In addition, a longer disease duration and higher temperature were observed in patients with diarrhea. Symptom duration was variable, with a median of 12 days and a range of 1-55 days. Statistical analysis indicated that patients with a duration of symptoms ≥12 day had more severe symptoms and a worse prognosis. Patients who complained of diarrhea had 2.7 times the odds of a longer duration of symptoms, and those with a history of chronic lung disease have 7.2 times the odds of a longer duration of symptoms. CONCLUSION: GIT manifestations (mainly diarrhea) and the duration of symptoms of COVID-19 provide prognostic evidence of COVID-19 outcomes, irrespective of earlier categorization by the World Health Organization. Thus, patients with mild symptoms who present with diarrhea and a duration of symptoms longer than 12 days are expected to have a worse prognosis.
RESUMO
BACKGROUND: No previous study has investigated the adherence rate of North-African pulmonologists to the 2017-GOLD PTGs. AIMS: To investigate the adherence rate of Tunisian pulmonologists to the 2017-GOLD PTGs and to identify the barriers to their adherence. METHODS: This was a cohort study involving clinically stable COPD patients who presented to a pulmonology outpatient consultation. The patients were classified as having been appropriately and inappropriately (over- or undertreatment) treated for the GOLD group. Logistic regression was performed to determine the adherence barriers to the 2017-GOLD PTGs. RESULTS: A total of 296 patients were included (88.1% males, mean age: 68 ± 10 years; GOLD A (7.1%), B (36.1%), C (4.1%), and D (52.7%)). The pulmonologists' adherence rate to the 2017-GOLD PTGs was 29.7%. There was a significant statistical difference between the adherence rates among the four GOLD groups (A: 19.0%, B: 20.6%, C: 8.3%, and D: 39.1%; p = 0.001). Differences were statistically significant between the GOLD group D and groups B (p = 0.001). Differences were statistically significant between the GOLD group D and groups B (p = 0.001). Differences were statistically significant between the GOLD group D and groups B (. CONCLUSION: The adherence rate of Tunisian pulmonologists to the 2017-GOLD PTGs is low. It seems that the patients' age, socioeconomic level, national health insurance coverage, and GOLD groups influenced their adherence.
