Prevalence of Obstructive Sleep Apnea Among Atrial Fibrillation Patients: A Cross-Sectional Study from Jordan.

Background: Obstructive Sleep Apnea (OSA) is a common respiratory disorder that causes intermittent upper airway collapse during sleep and can lead to various acute cardiovascular complications. Atrial Fibrillation (AF) is the most common sustained cardiac arrhythmia and is associated with an increased risk of cardiovascular hospitalization and all-cause mortality. Our study aimed to investigate the prevalence of individuals with AF and those considered at high risk for OSA. Methods: A cross-sectional study was conducted with a population comprising patients who had visited KAUH cardiology clinics between 2017-2019; subjects were categorized into AF patients and general cardiology patients. Patients were surveyed for OSA using the Berlin Questionnaire to assess the degree of OSA symptoms and to classify patients into high- or low-risk groups based on their responses. Results: Of the 656 patients, 545 met our inclusion criteria, of whom 192 were diagnosed with AF. Comparable demographic characteristics were observed between the AF and non-AF groups, barring higher rates of obesity (p=0.001) and smoking (p=0.042) in the AF group. The prevalence of high-risk OSA was significantly higher in AF patients (68.2%) compared to non-AF patients (29.4%), with an adjusted odds ratio of 2.473 times (95% CI: 1.434 -4.266, p=0.001) greater for AF. The age, gender, and BMI categories did not differ significantly between the two groups. Binary logistic regression revealed significant associations between OSA and risk factors such as asthma (OR=4.408, 95% CI: 2.634-7.376, p=0.001). Conclusion: These results serve to display a statistically significant increase in high-risk OSA in existing AF patients, irrespective of the presence of conventional OSA risk factors; this could imply a more immediate and direct relationship between both diseases and calls to include routine screening for OSA in patients diagnosed, newly or otherwise, with AF.

The Influence of Vaginal Dysbiosis on Intracytoplasmic Sperm Injection Outcome.

In women of reproductive age, vaginal infection is a gynaecological condition with various health consequences. Bacterial vaginosis, vulvovaginal candidiasis, and aerobic vaginitis are the most prevalent types of infection. Although reproductive tract infections are known to impact human fertility, no consensus guidelines on microbial control in infertile couples undergoing in vitro fertilization therapy are currently available. This study aimed to determine the effect of asymptomatic vaginal infections on the outcome of intracytoplasmic sperm injection in infertile Iraqi couples. Forty-six asymptomatic infertile Iraqi women were evaluated for genital tract infections by taking a vaginal sample on ovum pick-up for microbiological culture during their intracytoplasmic sperm injection treatment cycle. Based on the acquired results, a multi-microbial community colonized the participant's female lower reproductive tract, and only 13 women achieved pregnancy compared to 33 who did not. Candida albicans was found in 43.5% of the cases, 39.1% Streptococcus agalactiae, 19.6% Enterobacter species, 13.0% Lactobacillus, 8.7% Escherichia coli, 8.7% Staphylococcus aureus, 4.3% Klebsiella, and 2.2% Neisseria gonorrhoeae. However, no statistically significant effect was observed on the pregnancy rate except for Enterobacter spp. and Lactobacilli. In conclusion, the majority of patients had a genital tract infection; Enterobacter spp. had a substantial negative influence on the pregnancy rate, and lactobacilli were highly related to positive outcomes in participating females.

An observational study of the occurrence of acute coronary syndrome (ACS) among jordanian patients: Identifying the influence of Ramadan Fasting.

INTRODUCTION: Patients with Acute Coronary Syndrome (ACS) tend to face several health issues during the Holy month of Ramadan, due to the change in dietary patterns. This study aims to investigate the influence of fasting during Ramadan on the occurrence of ACS. METHODS: The study followed a retrospective observational design, and was conducted in King Abdullah University Hospital (KAUH) of Jordan, during the period of June 06, 2016 to Aug 08, 2016 and May 27, 2017 to July 27, 2017. Data was collected from a sample of 226 male and female patients, aged between 20 and 80 years with major diagnosis of acute coronary syndrome. Therefore, this is a case series of ACS patients. RESULTS: Findings of the study indicated that, Ramadan fasting is insignificantly related to the occurrence of ACS, since no significant difference was found in the incidence of hypertension (65%), diabetes (51.7%), unstable angina (56.6%) and coronary artery disease (CAD) (57.6%) findings during and after Ramadan respectively. Similar, findings were attained for patients' final diagnosis which had normal Kidney Function Test (KFT) (72.5%), platelets (91.5%), and Ejection Fraction (EF) (64.6%). Also, no significant difference was found between patients' smoking status (61.0%), hospital stay (89.8%) and discharge rate (96.9%). CONCLUSION: The study concluded that there is an insignificant association of Ramadan fasting on the cardiac patients and occurrence of acute coronary syndrome.

LTA, LEP, and TNF-a Gene Polymorphisms are Associated with Susceptibility and Overall Survival of Diffuse Large B-Cell lymphoma in an Arab Population: A Case-Control Study.

OBJECTIVE: In this study, we aimed to explore the relationship between five selected proinflammatory and immune-mediated genes (TNF rs1800629G>A, rs361525G>A, rs1799964T>C, LTA rs1800683G>A, rs909253A>G, TNFAIP8 rs1042541C>T, LEPR rs1327118G>C, and LEP rs2167270G>A) and the risk and overall survival of DLBCL patients within the Jordanian Arab population. METHODS: One hundred twenty-five patients (125) diagnosed with DLBCL at the King Abdullah University Hospital (KAUH) between 2013 and 2018 and 238 healthy cancer-free control subjects with similar geographic and ethnic backgrounds to the patients were included in the study. Genomic DNA was extracted from the formalin-fixed paraffin-embedded tissues of the subjects and from peripheral blood samples of the controls. The Sequenom MassARRAY® sequencer system (iPLEX GOLD) was used. The analyses included assessments of population variability and survival. RESULTS: Our study showed significant differences in the distribution of the studied polymorphisms of DLBCL between the patients and controls for TNF rs1800629G>A, LTA rs909253 G>A and LEP rs2167270 G>A. TNF rs1800629G>A (p = 0.01), in which the G allele harbors a higher risk of DLBCL (GG and GA genotypes when compared with AA genotype) (p = 0.044). The LTA rs909253 A>G polymorphism is associated with a higher risk of DLBCL in the allelic model (p = .004).  LEP rs2167270 G>A polymorphism is associated with a decreased risk of DLBCL in the recessive mode models (p = .03). Subjects with the dominant model for TNF-a rs1799964 (TT genotype in comparison with the combined TT/TC genotype) and patients with the homozygous genotype (GG) of rs361525 have better overall survival rates. CONCLUSION: Our results confirmed the diversity and the heterogeneity of the disease. Although the study has a limitation because of its relatively small size, it clearly emphasizes the significance of ancestry and genetic composition as the determinants of DLBCL risk and behavior.

COVID-19 outbreak in Jordan: Epidemiological features, clinical characteristics, and laboratory findings.

BACKGROUND: In March 2020, an outbreak of coronavirus 19 (COVID-19) was detected in the North of Jordan. This retrospective study is the first from Jordan to report the epidemiologic, clinical, laboratory, and radiologic characteristics of COVID-19 infected patients. METHODS: All patients with laboratory-confirmed COVID-19 infection by RT-PCR in the North of Jordan admitted between March 15 and April 2, 2020 were included. The clinical features, radiological, and laboratory findings were reviewed. RESULTS: Of 81 patients affected, 79 (97.5%) shared a common exposure to four recent travelers from endemic areas. The mean age was 40 years. Although about half (44 [54.3%]) were females, symptomatic patients were mostly females (75%). The most common presenting symptoms were nasal congestion, sore throat and dry cough. Less than one-third (31%) had chronic diseases. Although 84% of patients reported receiving Bacille Calmette-Guérin (BCG) vaccination, more asymptomatic patients had BCG than symptomatic (p = 0.017). Almost all patients (97.5%) had an elevated D-dimer level. Erythrocyte sedimentation rate (ESR) and c-reactive protein were elevated in 50% and 42.7% of patients, respectively. High ESR found to be the predictor of abnormal chest radiograph observed in 13 (16%) patients with OR of 14.26 (95% CI 1.37-147.97, p = 0.026). CONCLUSIONS: An outbreak of COVID-19 infection in northern Jordan affected more females and relatively young individuals and caused mainly mild illnesses. The strict outbreak response measures applied at early stages probably contributed to the lenient nature of this outbreak, but the contribution of other factors to such variability in COVID-19 presentation is yet to be explained.

The Impact of the Genetic Polymorphism in DNA Repair Pathways on Increased Risk of Glioblastoma Multiforme in the Arab Jordanian Population: A Case-Control Study.

INTRODUCTION: Among the Jordanian population, brain tumors are the tenth most common type of cancers in both males and females, comprising 2.8% of all newly diagnosed neoplasms. Diffuse gliomas are the most prevalent and the most aggressive primary brain tumors in adults. The incidence of diffuse gliomas varies among different populations; this variation is partially linked to genetic polymorphisms. The purpose of the study is to examine the association between (BRCA1 rs799917G>A, rs1799966T>C, EXO1 rs1047840G>A, EME1 rs12450550T>C, ERCC2 rs13181T>G, rs1799793C>T, and XRCC1 rs1799782G>A) DNA repair gene polymorphisms and glioblastoma multiforme (GBM) susceptibility, and survival in the Jordanian Arab population. METHODS: Eighty-four patients diagnosed with glioblastoma multiforme at the King Abdullah University Hospital (KAUH) between 2013 and 2018 and 225 healthy cancer-free control subjects with similar geographic and ethnic backgrounds to the patients were included in the study. Genomic DNA was extracted from the formalin-fixed paraffin-embedded tissues of the subjects. The Sequenom MassARRAY® sequencer system (iPLEX GOLD) was used. The analyses included assessments of population variability and survival. RESULTS: This study is the first to address the relationship between BRCA1 rs1799966 and rs799917 SNP, and the risk of GBM among the Arab Jordanian population. The findings of the study show that BRCA1 rs799917 is associated with decreased risk of GBM in the recessive model (AA vs G/G-A/G: OR, 0.46, 95% CI, 0.26-0.82, p=0.01) and the same SNP is associated with increased risk of GBM in the overdominant model (AG vs G/G-A/A: OR, 1.72, 95% CI, 1.02-2.89, p=0.04).

Prevalence of undiagnosed COPD in male patients with coronary artery disease: a cross-sectional study in Jordan.

Purpose: COPD and coronary artery disease (CAD) are common chronic diseases with shared risk factors. COPD continues to be largely underdiagnosed and undertreated. We aimed to describe the prevalence and predictors of undiagnosed COPD in Jordanian men with CAD. Patients and methods: In a cross-sectional study conducted at a referral center in Jordan, male patients who underwent coronary angiography for suspected CAD and reported ≥10 pack-year of cigarette smoking were recruited. Pre- and post-bronchodilator spirometry was undertaken for all participants, and COPD was defined as post-bronchodilator FEV1/FVC <70%. The finding of ≥50% coronary luminal narrowing confirmed the presence of CAD. Results: Spirometry was undertaken for 376 men with mean age of 56.02±10.55 years, and 72.6% were active cigarettes smokers with a mean pack-year of 55.89±34.25. A CAD diagnosis was confirmed in 300 (79.8%) men. Spirometric criteria for COPD were met in 76 (15.7%) patients, of whom 91.5% were not previously diagnosed. COPD-related symptoms were common: chronic cough (44.4%), dyspnea (66.2%), and wheezes (27.9%). COPD was more common in patients with (18.0%) compared to patients without (6.6%) CAD (P=0.014). Multivariate logistic regression showed that the risk of COPD was higher in patients with CAD (OR 3.16, 95% CI, 1.10-9.09, P=0.033) and in those with chronic bronchitis (OR 13.07, 95% CI, 6.69-25.52, P<0.001). Conclusion: There was a high prevalence of COPD among male patients with CAD and most were underdiagnosed despite having respiratory symptoms. Male smokers with CAD and respiratory symptoms should be evaluated for airflow limitation and the presence of COPD.

Demographic situation and prospects in Africa.

PIP: Summarizes recent trends and projections through the year 2000 of population size, population growth, fertility, mortality, and age structure in Africa. Fertility is very high, mortality is fairly high but gradually declining, the age distribution is heavily weighted toward children, and the population growth rate has been increasing--it is at 2.77% and may rise yet more. All of these characteristics vary from region to region. It is estimated that fertility will not decline much if at all in the next 20 years due to a number of sociological factors, and the population may increase from 132 million in 1980 to 246 million or more in 2000. Several graphs and data tables are appended.^ieng
