Workplace activity limitation and quality of life: A study on rheumatoid arthritis patients.

BACKGROUND: Rheumatoid arthritis (RA) causes disabilities that affect people in working age and can impair their working activity and quality of life (QoL). OBJECTIVES: To assess work activity limitation and QoL among RA patients and to explore the associated risk factors. METHODS: A cross-sectional study on 344 RA patients was conducted at the outpatient clinic using a number of standardized questionnaires including the Health Assessment Questionnaire Disability Index, Workplace Activity Limitation Scale, and RA QoL. Clinical examinations were also performed including the measurement of pain intensity, assessment of disease activity, and the Rheumatoid Arthritis Severity Scale. RESULTS: Most of the employed participants (87%) experienced high work activity limitations. Increasing work limitations were significantly associated with a decrease in QoL domains scores. The most significant risk factors affecting work limitation by logistic regression were high disease activity, the severity of the disease, married females, and a high health assessment disability index among RA patients. CONCLUSIONS: RA patients experience limitations that affect their productivity at work and their QoL. Paying more attention to early management to prevent the upcoming unfavorable health and economic consequences for RA patients is significantly important.

Maintenance of Antibody Response in Egyptian Healthcare Workers Vaccinated with ChAdOx1 nCoV-19 Vaccine during Delta and Omicron Variants Pandemic: A Prospective Study.

Background: The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is a constantly evolving virus, resulting in an increased burden on the existing COVID-19 vaccines. Healthcare workers (HCWs) are the first line of defense against the coronavirus disease 2019 (COVID-19) pandemic and have been prioritized among the risk categories receiving the COVID-19 vaccine. This work aimed to investigate the maintenance of antibody response of the Oxford−AstraZeneca vaccine (ChAdOx1/nCoV-19). Methods: Anti-spike immunoglobulin G (IgG) was measured at baseline point (immediately prior to vaccination) and 12- and 24-week (w) points following vaccination. Adverse reactions to the vaccine were reported. Participants were followed up for the incidence of COVID-19 during the 12 w interval between vaccination doses for 24 w after the second dose. Results: A total of 255 HCWs participated in the study. Prior to vaccination, 54.1% experienced COVID-19, 88.2% were seropositive after the first dose, while seropositivity reached 95.7% after the second dose. Following the first and second doses, the anti-spike IgG serum level was significantly higher in subjects with past COVID-19 than in others (p < 0.001 and =0.001, respectively). Conclusions: The Oxford−AstraZeneca vaccine is generally safe and provides a highly effective long-term humoral immune response against the Delta and Omicron variants of SARS-CoV-2.

Ankle and foot pathologies in early rheumatoid arthritis, what can ultrasound tell us?

BACKGROUND: Rheumatoid arthritis (RA) is a systemic autoimmune polyarticular disease. Despite being commonly affected in RA, the ankle and foot do not receive much attention, particularly in early disease. The precise diagnosis of their involvement and its impact on health is a clinical challenge that requires accurate assessment. AIM: To determine the role of ultrasound in evaluation of ankle and foot pathologies and assess its impact on functional activity in newly diagnosed RA patients. METHODS: The study was conducted on 152 RA patients and 52 healthy controls. Patients were subjected to history taking, clinical examination, and ultrasound scan. Impact on health was measured by health assessment questionnaire, as well as foot function index. RESULTS: In a cohort of patients with early RA with median duration of 1 month, tibialis posterior (TP) tenosynovitis (45.4%) was the most common pathology, followed by tibiotalar (TTJ) synovitis (39.8%), and peroneal tenosynovitis (39.1%). In terms of disease duration, TTJ (P = .001) foot pathologies were less common in early RA and tended to worsen over time, whereas TP (P = .048) and peroneal tenosynovitis (P = .011) were more common in early RA. In multivariate analysis TTJ, subtalar synovitis, forefoot pathologies, TP tenosynovitis, and Achilles enthesitis were found to be significant predictors of functional disability. The most important predictors of ankle pain were TTJ synovitis, TP tenosynovitis, peroneal tenosynovitis, and plantar fasciitis. CONCLUSION: Ankle and foot involvement is a common issue of early RA, and it has a significant impact on quality of life. Ultrasound is a reliable tool for evaluating various abnormalities in this complex area, allowing for better management.

Proinsulin/insulin ratio as a predictor of insulin resistance and B-cell dysfunction in obese Egyptians ((insulin resistance & B-cell dysfunction in obese Egyptians)).

Insulin resistance (IR) and ß-cell dysfunction are key pathological features of type 2 diabetes mellitus, the aim of this study was to investigate the role of proinsulin level and proinsulin/insulin ratio in early prediction of beta cell dysfunction and insulin resistance in obese Egyptian adolescent. PATIENTS AND METHODS: This Case control study was conducted from June 2017 to March 2018. Total of 60 patients were divided into 2 groups after exclusion of patients with diabetes: normal body weight group and Obese group. Demographic, clinical data were collected. Laboratory investigation included fasting insulin, proinsulin, and estimation of HOMA IR and HOMA-B were done. RESULTS: There are highly statistically significant increase in obese group regarding insulin, proinsulin, proinsulin/insulin ratio and HOMA-IR while there is significant decrease in HOMA-B in this group. The best cutoff value of Proinsulin in prediction of beta cell function was ≥7.829 pmol/L with sensitivity 95.8, specificity 72.2. The best cutoff value of Proinsulin/insulin ratio in prediction of insulin resistance was ≥0.1545 with sensitivity 87.5, specificity 61.1. CONCLUSION: both beta cell dysfunction and insulin resistance increased in obese group and so increased risk of type 2 diabetes. We found that Pro insulin/insulin ratio is a significant predictor for insulin resistance and Proinsulin is good predictor for beta cell dysfunction.

Assessment of the Correlation Between Preoperative and Immediate Postoperative Gastric Volume and Weight Loss After Sleeve Gastrectomy Using Computed Tomography Volumetry.

BACKGROUND: Laparoscopic sleeve gastrectomy (LSG) has achieved excellent results in treatment of morbid obesity. The present study aimed to evaluate the impact of the preoperative gastric volume, volume of the remaining gastric pouch, and volume of the resected stomach on weight loss after LSG. METHODS: Patients with morbid obesity who underwent LSG were investigated by CT volumetry before and 1 week after LSG to measure the volume of the stomach before and after the procedure, and the volume of the resected stomach was also calculated. The percentage of excess weight loss (EWL) and decrease in body mass index (BMI) at 6 months postoperatively were measured and correlated with preoperative and postoperative gastric volumes. RESULTS: Forty-seven patients (44 females) were included to the study. A significant decrease in the gastric volume and BMI after LSG was noted. Preoperative gastric volume was positively correlated with preoperative BMI (r = 0.723, p < 0.00001) but not correlated with %EWL at 6 months. The volume of the remaining gastric pouch was positively correlated with BMI at 6 months postoperatively (r = 0.597, p < 0.00001) and negatively correlated with %EWL (r = -0.7495, p < 0.00001). The correlation between the size of resected stomach and %EWL was statistically insignificant, yet the mean percentage of the resected stomach was directly correlated to %EWL. CONCLUSION: The preoperative volume of the stomach was positively correlated with baseline BMI, but not correlated with %EWL. The size of the remaining gastric pouch and the percentage of the resected stomach had significant impact on %EWL after LSG.

Correlation Between the Number of Ghrelin-Secreting Cells in the Gastric Fundus and Excess Weight Loss after Sleeve Gastrectomy.

BACKGROUND: Weight loss after laparoscopic sleeve gastrectomy (LSG) has been mainly attributed to the restriction of gastric volume; however; other factors may contribute to weight loss after LSG. This study aimed to investigate the correlation between the number of ghrelin-secreting cells in the gastric fundus and excess weight loss (EWL) at 12 months after LSG. METHODS: The surface area of the gastric fundus was measured postoperatively in square centimeter. Histopathologic examination of the gastric fundus was made to estimate the number of ghrelin-secreting cells per square centimeter then was multiplied by the surface area of the fundus to calculate the total number of ghrelin-secreting cells in the fundus. The number of ghrelin-secreting cells was correlated with EWL and BMI at 12 months postoperatively. RESULTS: The present study included 39 patients of a mean age of 33.7 years. The mean %EWL at 12 months was 59.7 ± 12.7. The mean total number of ghrelin-producing cells in the gastric fundus was 26,228.4 ± 16,995.3. The total number of ghrelin-secreting cells had a weak positive correlation with BMI at 12 months (r = 0.2891, p = 0.07), and weak negative correlation with %EWL (r = - 0.1592, p = 0.33). CONCLUSION: There was a weak correlation between the total number of ghrelin-producing cells in the gastric fundus and plasma ghrelin levels with EWL after LSG.
