Introduction: Obstructive sleep apnea is a sleep complaint among type 2 diabetes mellitus patients that has a deleterious effect on health with immediate and long-term impacts. Despite its impacts, data on the magnitude and predictors of obstructive sleep apnea among type 2 diabetes mellitus patients in Ethiopia is still limited. Thus, this study was conducted to determine how common a high risk of obstructive sleep apnea is and its predictors among type 2 diabetes mellitus patients receiving follow-up care at the chronic illness follow-up clinic at the University of Gondar Comprehensive Specialized Hospital, Northwest Ethiopia, 2022.

Phosphorus recovery as K-struvite from a waste stream: A review of influencing factors, advantages, disadvantages and challenges.

Currently, the depletion of natural resources and contamination of the surrounding environment demand a paradigm shift to resource recycling and reuse. In this regard, phosphorus (P) is a model nutrient that possesses the negative traits of depletion (will be exhausted in the next 100 years) and environmental degradation (causes eutrophication and climate change), and this has prompted the scientific community to search for options to solve P-related problems. To date, P recovery in the form of struvite from wastewater is one viable solution suggested by many scholars.

Khat: A Substance of Growing Abuse with Adverse Drug Interaction Risks.

The growing global availability of the stimulant shrub, khat, has aroused widespread concern. This paper is a review of possible adverse interactions between khat and conventional drugs. Khat chewing has been shown to reduce the bioavailabilities of orally co-administered antibiotics, ampicillin, amoxicillin, cephradine and tetracyclineHCl, and the antimalarial drug, chloroquine.

Khat and synthetic cathinones: Emerging drugs of abuse with dental implications.

The rising global availability of the stimulant and euphoric substances, khat and synthetic cathinones, has become a cause for concern in many countries, including the United States. Both substances are illegal in United States, although this has not deterred their use. Besides central nervous system effects, these drugs also cause sympathomimetic and orodental adverse effects, similar to those of amphetamine.

Status of stem cells in diabetic nephropathy: predictive and preventive potentials.

Background: Recruitment of stem cells to sites of tissue injury constitutes an important mechanism aimed at tissue repair and regeneration. However, it is not clear how the diabetic milieu affects the viability of endogenous stem cells. Thus, we tested the hypothesis that diabetes mellitus is associated with increased apoptosis which, in turn, contributes to reduction in stem cells and the manifestation of type 2 diabetic nephropathy.

Effects of acrylic resin monomers on porcine coronary artery reactivity.

The purpose of the present investigation was to assess the reactivity of porcine coronary arteries under in vitro conditions following their exposure to methyl methacrylate (MMA) and hydroxyethyl methacrylate (HEMA) monomers. Confirming previous studies using rat aortas, both MMA and HEMA induced acute/direct relaxation of coronary ring preparations, which was partly dependent on the endothelium. With prolonged tissue exposure, both monomers caused time- and concentration-dependent inhibition of receptor-mediated contraction of the vascular smooth muscle caused by prostaglandin F2∝ (PGF2∝), with HEMA causing more inhibition than MMA.

Prevalence of trachoma at sub-district level in ethiopia: determining when to stop mass azithromycin distribution.

Background: To eliminate blinding trachoma, the World Health Organization emphasizes implementing the SAFE strategy, which includes annual mass drug administration (MDA) with azithromycin to the whole population of endemic districts. Prevalence surveys to assess impact at the district level are recommended after at least 3 years of intervention. The decision to stop MDA is based on a prevalence of trachomatous inflammation follicular (TF) among children aged 1-9 years below 5% at the sub-district level, as determined by an additional round of surveys limited within districts where TF prevalence is below 10%.

Mechanisms of load dependency of myocardial ischemia reperfusion injury.

Coronary artery disease and associated ischemic heart disease are prevalent disorders worldwide. Further, systemic hypertension is common and markedly increases the risk for heart disease. A common denominator of systemic hypertension of various etiologies is increased myocardial load/mechanical stress.

Intestinal parasite prevalence in an area of ethiopia after implementing the SAFE strategy, enhanced outreach services, and health extension program.

Background: The SAFE strategy aims to reduce transmission of Chlamydia trachomatis through antibiotics, improved hygiene, and sanitation. We integrated assessment of intestinal parasites into large-scale trachoma impact surveys to determine whether documented environmental improvements promoted by a trachoma program had collateral impact on intestinal parasites.

Methodology: We surveyed 99 communities for both trachoma and intestinal parasites (soil-transmitted helminths, Schistosoma mansoni, and intestinal protozoa) in South Gondar, Ethiopia.

Renal and glycemic effects of high-dose chromium picolinate in db/db mice: assessment of DNA damage.

This study examined renal and glycemic effects of chromium picolinate [Cr(pic)3] supplementation in the context of its purported potential for DNA damage. In preventional protocol, male obese diabetic db/db mice were fed diets either lacking or containing 5, 10 or 100 mg/kg chromium as Cr(pic)3 from 6 to 24 weeks of age; male lean nondiabetic db/m mice served as controls. Untreated db/db mice displayed increased plasma glucose and insulin, hemoglobin A1c, renal tissue advanced glycation end products, albuminuria, glomerular mesangial expansion, urinary 8-hydroxydeoxyguanosine (an index of oxidative DNA damage) and renal tissue immunostaining for γH2AX (a marker of double-strand DNA breaks) compared to db/m controls.

Mitochondrial complex I and NAD(P)H oxidase are major sources of exacerbated oxidative stress in pressure-overloaded ischemic-reperfused hearts.

We tested the hypothesis that pressure overload exacerbates oxidative stress associated with augmented mitochondrial permeability transition (MPT) pore opening and cell death in ischemic-reperfused hearts. Pressure overload decreased the level of reduced glutathione but increased nitrotyrosine and 8-hydroxydeoxyguanosine levels in ischemic-reperfused hearts. The activity of catalase, but not superoxide dismutase (SOD), was lower in ischemic-reperfused hearts perfused at higher pressure.

Effects of chromium picolinate on vascular reactivity and cardiac ischemia-reperfusion injury in spontaneously hypertensive rats.

Chromium picolinate [Cr(pic)(3)] is a nutritional supplement widely promoted to exert beneficial metabolic effects in patients with type 2 diabetes/impaired glucose tolerance. Frequent comorbidities in these individuals include systemic hypertension, abnormal vascular function and ischemic heart disease, but information on the effects of the supplement on these aspects is sparse. Utilizing male spontaneously hypertensive rats (SHR), we examined the potential impact of Cr(pic)(3) on blood pressure, vascular reactivity and myocardial ischemia-reperfusion injury (IRI).

Endothelial dysfunction in diabetes: potential application of circulating markers as advanced diagnostic and prognostic tools.

Endothelial dysfunction is a predisposing factor for vascular disease in diabetes, which contributes significantly to the mortality of diabetic patients. The currently utilized assessment methods of endothelial function/dysfunction in humans are associated with various limitations. Circulating endothelial-derived/associated markers have been proposed as potential alternatives for evaluation of the endothelium in condition of vascular disorders.
