Immunological changes in a cohort of COVID-19 survivors: Mansoura University experience.

Background: COVID-19 is a global pandemic that has affected millions of people all over the world since 2019. Infection with COVID-19 initiates a humoral immune response that produces antibodies against specific viral antigens, which in turn is supposed to provide immunity against reinfection for a period of time. The aim of this research was to study the kinetics of IgM and IgG antibodies against SARS-CoV-2. Methods: One hundred and seventeen post-COVID-19 participants were enrolled in the study.  Qualitative assessment of IgM and IgG antibodies over six months (three visits) post recovery was conducted. Results: The current study revealed a significant reduction in IgM and IgG titers between the first and second visits (p <0.001). After six months, the antibody titer had declined by 78.8% from the first visit for IgM and by 49.2% for IgG antibodies. Regarding younger age and male sex, statistically significant persistence of IgM antibodies was noticed at the six months follow up. Also, statistically significant persistent IgG immunity was found in male patients and diabetics by the end of the six months follow up. Conclusions: We observed a significant waning of IgM and IgG titers over a period of six months follow up.. The persistence of positive IgM and IgG antibodies by the end of six months was variable due to differences in age, gender and presence of diabetes mellitus.

Effect of a waste management intervention program on knowledge, attitude, and practice (KAP) of nurses and housekeepers: a quasi-experimental study, Egypt.

BACKGROUND: Improper healthcare waste management practice is alarming in developing countries because resources are inadequate and waste management is often delegated to poorly educated and untrained laborers. This study aimed to compare the pre-KAP versus post-KAP towards the waste management program for nurses and housekeepers. In addition, it aimed to explore possible factors affecting the pre- and post-KAP in Mansoura Emergency University Hospital, Egypt. SUBJECTS AND METHODS: One hundred thirty-three newly employed nurses, housekeepers, and those who need refreshment training as nominated by head nurses and link occupational health and safety nurses in the hospital were recruited for the study. The study's intervention included multiple training sessions using a PowerPoint presentation in Arabic with appropriate illustrations followed by an open discussion. An Arabic self-administered questionnaire containing demographic and occupational history, knowledge (27 questions), attitude (10 questions), and practice (9 questions) was used pre- and post-intervention. RESULTS: The overall KAP scores among the studied healthcare workers were significantly higher after the intervention. The pre- and post-knowledge scores were significantly different with respect to education, job description, and duration of employment (p < 0.05). The post-attitude scores were significantly different with respect to education and job description only (p < 0.05). The total pre-practice scores were significantly different with respect to education and job description (p < 0.05). However, the post-practice scores were significantly different with respect to sex, age, education, and job description (p < 0.05). CONCLUSION: There was a significant improvement in the KAP scores post-intervention. The post-knowledge and attitude scores were significantly better in nurses and participants with a higher education. The post-practice score was significantly better for females, participants with an age ≥ 30 years, higher education, and nursing jobs. The combination of training and supervision was crucial for the success of waste management programs. Higher education levels are required for housekeepers to be capable of gaining better knowledge, follow rules, and be ready for any challenges in the future.

Molar pregnancy with a coexisting living fetus: a case series.

BACKGROUND: Coexistence of molar pregnancy with living fetus represents a challenge in diagnosis and treatment. The objective of this study to present the outcome of molar pregnancy with a coexisting living fetus who were managed in our University Hospital in the last 5 years. METHODS: We performed a retrospective analysis of patients who presented with molar pregnancy with a coexisting living fetus to our Gestational Trophoblastic Clinic, Mansoura University, Egypt from September, 2015 to August, 2020. Clinical characteristics of the patients, maternal complications as well as fetal outcome were recorded. The patients and their living babies were also followed up at least 6 months after delivery. RESULTS: Twelve pregnancies were analyzed. The mean maternal age was 26.0 (SD 4.1) years and the median parity was 1.0 (range 0-3). Duration of the pregnancies ranged from 14 to 36 weeks. The median serum hCG was 165,210.0 U/L (range 7662-1,200,000). Three fetuses survived outside the uterus (25%), one of them died after 5 months because of congenital malformations. Histologic diagnosis was available for 10 of 12 cases and revealed complete mole associated with a normal placenta in 6 cases (60%) and partial mole in 4 cases (40%). Maternal complications occurred in 6 cases (50%) with the most common was severe vaginal bleeding in 4 cases (33.3%). There was no significant association between B-hCG levels and maternal complications (P = 0.3). CONCLUSION: Maternal and fetal outcomes of molar pregnancy with a living fetus are poor. Counseling the patients for termination of pregnancy may be required. TRIAL REGISTRATION: The study was approved by Institutional Research Board (IRB), Faculty of Medicine, Mansoura University (number: R.21.10.1492).

Personal protective equipment used by obstetricians and obstetric nurses during the COVID-19 pandemic in Mansoura, Egypt.

Background: This study was done to describe the pattern of personal protective equipment (PPE) use, associated factors, and adverse events among obstetricians and obstetric nurses in obstetrics & gynecology departments.  Methods: A cross sectional study was conducted in Obstetrics & Gynecology departments in three hospitals (physician & nurses n=252) using an online Google form including demographic and occupational health data, type of available personal protective equipment during usual care, CS and emergency labor, infection control measures and hazards of full PPE use. Results Full PPE use was 37.7% during CS and 34.9% during emergency labor. The significant predictors of wearing full PPE during CS were daily work hours > 8 hours and receiving formal training about PPE use. During CS & emergency labor most of HCws used sterile gloves and sterile fluid resistant gowns and surgical mask.to less extent used face shields or tight fitting googles and one tenth (11.8%) only used N95. The most common health effects of full PPE use was sense of heat (79.5%) .Conclusion: During the COVID-19 pandemic more vigorous respiratory (N95 mask) and eye protection is required during aerosol-generating procedures. Formal training is an evident predictor for full PPE use.

Multidetector computed tomography evaluation of synchronous lymphoma and other solid malignancies.

OBJECTIVE: The objective of this study is to review the multidetector computed tomography (MDCT) findings of synchronous lymphoma and other solid malignancies. PATIENTS AND METHODS: This retrospective study included 18 patients confirmed with diagnosis of lymphoma and other solid malignancies. They were 8 women and 10 men (mean age, 62.5 year; range, 44-73 years). CT scanning was performed on one of the two systems: 64 MDCT in 11 patients and 6 MDCT in 7 patients. All 36 malignancies were underwent pathological evaluation. RESULTS: All cases were confirmed pathologically. Lymphomas were Hodgkin disease ( n = 5 patients) and non-Hodgkin lymphoma ( n = 13 patients). Hepatocellular carcinoma was detected in five patients. Bronchogenic carcinoma was detected in two patients. Renal cell carcinoma was detected in two patients. Breast carcinoma was detected in two patients. Prostatic carcinoma was detected in two patients. Gastric carcinoma was detected in two patients. Endometrial carcinoma was detected in one patient. Colonic carcinoma was detected in one patient. Thyroid carcinoma was detected in one patient. CONCLUSIONS: MDCT scanning is accurately imaging modality for the evaluation of synchronous lymphoma and other solid malignancies. More reports and accumulation of such cases should help to clarify the mechanisms, contribute to a further understanding of this phenomenon, and may lead to a new treatment strategy for synchronous lymphoma and other solid malignancies.

Could photodynamic therapy be utilized as a treatment modality for oral lichen planus?

BACKGROUND: Oral lichen planus (OLP) is a chronic inflammatory disease. There is no standard treatment modality for OLP. Recently, photodynamic therapy (PDT) has been advocated as a new treatment modality for OLP. AIM: The aim of the present study is to compare the effect of PDT using methylene blue (MB) as a photosensitizer to the effect of topical corticosteroids in the treatment of erosive OLP lesions. MATERIALS AND METHODS: Our study included 20 patients with erosive OLP. Patients were divided into two groups. The study group included 10 patents which received MB-PDT. Patients were instructed to use MB as mouth path for 5 min. After 10 min, we applied focal red light on OLP lesions (wavelength 660 nm, Intensity 100-130 m W/cm2) for 2 min. The PDT was applied twice a week for four weeks. In the control group, 10 patients were instructed to apply topical betamethasone valerate ointment 100 mg on OLP lesion three times per day for four weeks. Subjective, objective scores and lesion size were recorded at time zero, after 2 weeks and after 4 weeks from the start of treatments. RESULTS: Both groups showed statistically significant differences between time zero and the 4th week of treatment in subjective, objective scores and the area of the lesions. MB-PDT showed a higher degree of improvement than topical corticosteroids between time zero and the 4th week of treatment. CONCLUSION: Photodynamic therapy can be used as a treatment for erosive OLP. PDT offers improvement of OLP subjective and objective scores without major side effects.

Work profile and associated health hazards among nursing students at Mansoura University, Egypt.

Nursing students are increasingly undertaking paid term-time employment to finance their living expenses and studies. The objectives of this study are to estimate its prevalence, factors associated, and possible health hazards. A cross-sectional study was conducted of nursing students using a questionnaire that included sociodemographic and employment data, reasons for working, possible health hazards in the workplace, and perceived effects on academic performance. The prevalence of student paid employment was found to be 23.3%. Being male and belonging to a low social class were independently associated with the likelihood of working while studying. Financial support was the main reason for student employment. Workplace hazards included noise, temperature extremes and psychosocial stressors. Sleep disorders were the most frequent health effects followed by musculoskeletal complaints. Nursing students are at risk from many deleterious health effects which are not covered by occupational health and safety programmes.

Les étudiants en soins infirmiers sont de plus en plus nombreux à avoir un activité rémunérée durant l'année universitaire dans le but de subvenir à leurs besoins et de financer leurs études. La présente étude a pour objectif d'estimer la prévalence de ce type d'activité, les facteurs et les risques sanitaires qui y sont associés. Une étude transversale a été conduite auprès d'étudiants en soins infirmiers à l'aide d'un questionnaire incluant des données socio-démographiques et sur l'emploi, les raisons de travailler, les risques sanitaires possibles sur le lieu de travail, et les conséquences perçues sur les performances universitaires. La prévalence des emplois étudiants rémunérés a été estimée à 23,3%. Le fait d'être de sexe masculin et l'appartenance à une classe sociale basse avaient une association indépendante avec la probabilité de travailler pendant les études. Un besoin de soutien financier était la raison principale de l'emploi étudiant. Les risques sur le lieu de travail incluaient le bruit, des températures extrêmes et des facteurs de stress psychologiques. Les conséquences sur la santé les plus fréquentes étaient des troubles du sommeil, suivis par des douleurs musculosquelettiques. Les étudiants en soins infirmiers sont exposés à des risques nocifs pour la santé qui ne sont pas pris en compte par les programmes de santé et de sécurité au travail

Interleukin-6, intracellular adhesion molecule-1, and glycodelin A levels in serum and peritoneal fluid as biomarkers for endometriosis.

OBJECTIVE: To compare levels of interleukin-6 (IL-6), intracellular adhesion molecule-1 (ICAM-1), and glycodelin A in serum and peritoneal fluid of patients with and without endometriosis, and to correlate levels with disease stage. METHODS: An observational study was undertaken at Mansoura University Hospital, Egypt, between March 2014 and June 2015. Patients aged 21-48 years laparoscopically diagnosed with endometriosis and those without endometriosis who underwent laparoscopy for tubal ligation were included. Levels of IL-6, ICAM-1, and glycodelin A were measured in samples of serum and peritoneal fluid. Receiver operating characteristic curves were used to evaluate diagnostic accuracy. RESULTS: Forty-eight women with endometriosis and 20 without the disorder were included. IL-6 and glycodelin A levels in serum and peritoneal fluid were higher in the endometriosis group than in the control group (P<0.001 for all); ICAM-1 levels did not differ. The sensitivity and specificity values were 93.8% and 80.0% for serum IL-6, 58.3% and 60.0% for serum ICAM-1, and 91.7% and 75.0% for serum glycodelin A. The corresponding values for peritoneal fluid markers were 85.4% and 89.0%, 60.4% and 50.0%, and 89.6% and 90.0%, respectively. IL-6 and glycodelin A levels in serum and peritoneal fluid increased with disease stage (P<0.001 for all). CONCLUSION: IL-6 and glycodelin A, but not ICAM-1, are potential biomarkers for endometriosis and are positively correlated with the disease stage.

Work-Related Psychosocial Hazards Among Emergency Medical Responders (EMRs) in Mansoura City.

PURPOSE: This research was done to assess levels of psychosocial stress and related hazards [(burnout, depression, and posttraumatic stress disorder (PTSD)] among emergency medical responders (EMRs). MATERIALS AND METHODS: A comparative cross-sectional study was conducted upon (140) EMRs and a comparative group composed of (140) nonemergency workers. The groups studied were subjected to semistructured questionnaire including demographic data, survey for job stressors, Maslach burn out inventory (MBI), Beck depression inventory (BDI), and Davidson Trauma scale for PTSD. RESULTS: The most severe acute stressors among EMRs were dealing with traumatic events (88.57%), followed by dealing with serious accidents (87.8%) and young victims (87.14%). Chronic stressors were more commonly reported among EMRs with statistically significant differences (P < 0.05) except for social support with colleagues and supervisors. EMRs had statistically significant higher levels of emotional exhaustion (EE) (20%) and depersonalization (DP) (9.3%) compared with comparative group (4.3%, 1.4% respectively). Also, there was no statistically significant difference between two groups as regards lower personal achievement or depression symptoms (P > 0.05). There was increased risk of PTSD for those who had higher stress levels from death of colleagues [odds ratio (OR) [95% confidence interval (CI)] = 2.2 (0.7-7.6), exposure to verbal or physical assault OR (95% CI) = 1.6 (0.5-4.4) and dealing with psychiatric OR (95% CI) 1.4 (0.53.7) (P > 0.05). CONCLUSION: EMRs group had more frequent exposure to both acute and chronic work-related stressors than comparative group. Also, EMRs had higher levels of EE, DP, and PTSD compared with comparative group. EMRs are in need for stress management program for prevention these of stress related hazards on health and work performance.

Neck-upper extremity musculoskeletal disorders among workers in the telecommunications company at Mansoura City.

OBJECTIVES: This study was to determine the prevalence and work-related risk factors of neck-upper extremity musculoskeletal disorders (MSDs) among video display terminal (VDT) users. METHODS: A comparative cross-sectional study was conducted; there were 60 VDT users and 35 controls. The participants filled in a structured questionnaire, had electrophysiological tests and an X-ray of the neck. RESULTS: The prevalence of MSDs was higher (28.3%) among VDTs users compared to controls (14.3%) with no statistically significant difference. The prevalence of cervical disorders with or without radiculopathy (18.3%) was the most common disorder followed by carpal tunnel syndrome (6.6%). The mean (SD) age of MSD cases (51 ± 7.2 years) was statistically significantly higher than of the controls (42.8 ± 9). Physical exposure to prolonged static posture (OR: 6.9; 95% CI: 0.83-57.9), awkward posture (OR: 5.5; 95% CI: 0.6-46.4) and repetitive movements (OR: 5.5; 95% CI: 0.65-46.4) increased risk of MSDs with a statistically significant difference for static posture only (p < .05). VDT users experienced more job dissatisfaction, work-overload and limited social support from supervisors and colleagues. CONCLUSION: VDT use did not increase the risk of neck-upper extremity MSDs. The risk increased with older age and static posture.
