Tuberculosis (TB) remains as one of the deadliest diseases after HIV globally with 95 % of deaths confined to low-and-middle income countries. Pakistan is fifth among the 22 high-burden TB countries with the incidence rate of 230/100,000 persons, however, studies related to prevalent Mycobacterium tuberculosis strains and their spread, drug resistance pattern and evolutionary genetics are inadequate. The present study was undertaken to highlight the circulation of M. tuberculosis strains causing drug resistant TB in our community by targeting the molecular marker IS6110 and then characterization of these strains as Beijing and Non-Beijing genotypes...

Objectives: Past research has reported an association between neighborhood disadvantage and healthy aging, but most of these studies utilize self-report measures of health or physical functioning and do not properly account for neighborhood selection effects, creating concerns regarding inflated associations. To overcome these limitations and provide a more stringent estimate of effects, the current study investigated the effect of neighborhood disadvantage on aging using newly developed epigenetic methods to assess rate of biological aging and marginal structural modeling (MSM) to account for potential confounds due to neighborhood selection...

Purpose of the study: Sleep is a key factor in maintaining positive health and well-being throughout life. Although the negative outcomes of sleep problems are becoming better understood, less is known about how intergenerational relationships might affect sleep. Thus, this investigation examines the dyadic associations of support for, stress over, and worrying about adult children on sleep quality for husbands and wives. Design and Methods: The sample included 186 heterosexual married couples drawn from the Family Exchanges Study...

Diffuse dermal angiomatosis of the breast (DDAB) is an uncommon ulcerative angiomatosis, which occurs in middle aged women with large pendulous breasts, a history of cigarette smoking, and risk factors for atherosclerosis. Based on its rarity, no well-defined therapeutic regimen has been elucidated. We report a case of DDAB in a woman with no history of smoking or radiographic evidence of occluded vasculature who presented with ulceration and pain-associated breast nodularity. She had a complete reproducible response to oral corticosteroids...

We describe an interesting case of pleomorphic fibroma of the subungual region in a middle aged woman who presented with a recurrence of thickening, lateral ridging, and a midline split of the right third fingernail, 20 years after initial excision. Histology of the specimen demonstrated hyperchromatic stellate cells within the superficial corneum, which were CD34 positive, consistent with a pleomorphic fibroma. Pleomorphic fibroma is a rare mesenchymal neoplasm characterized by atypical spindled cells amidst a collagenous stroma...

Objective: Older adults frequently report sleep problems and are at increased risk for cardiometabolic disruption. Experimental sleep restriction of younger adults has suggested that cortisol may be on the pathway between sleep restriction and cardiometabolic disease. We investigated whether the natural variation in sleep among older adults is associated with daytime cortisol level. Methods: Salivary cortisol samples and actigraphy sleep data were collected from a random subsample of participants in the National Social Life, Health and Aging Project, a nationally-representative probability sample of adults aged 62-90 (N=672)...

Although sex-specific differences in cardiovascular medicine are well-known, the exact influences of sex on the effect of cardiovascular drugs remain unclear. Women and men differ in body composition and physiology (hormonal influences during the menstrual cycle, menopause and pregnancy) and they present differences in drug pharmacokinetics (absorption, distribution, metabolism and excretion) and pharmacodynamics, so that is not rare that they may respond differently to cardiovascular drugs. Furthermore, women are also less often treated with evidence-based drugs thereby preventing optimization of therapeutics for women of all ages, experience more relevant adverse drug reactions than men, and remain under-represented in most clinical trials...

Background: Viral load (VL) monitoring for patients receiving antiretroviral therapy (ART) is recommended worldwide. However, the costs of frequent monitoring are a barrier to implementation in resource-limited settings. The extent to which personalized monitoring frequencies may be cost-effective is unknown. Methods: We created a simulation model parameterized using person-level longitudinal data to assess the benefits of flexible monitoring frequencies. Our data-driven model tracked HIV+ individuals for 10 years following ART initiation...

Background: Only scarce data exist on the association between obesity and disability in the oldest old. The purpose of this prospective study is to examine if body mass index and waist circumference (WC) are associated with incident mobility and activities of daily living (ADL) disability in nonagenarians. Methods: We used longitudinal data from the Vitality 90+ Study, which is a population-based study conducted at the area of Tampere, Finland. Altogether 291 women and 134 men, aged 90-91 years, had measured data on body mass index and/or WC and did not have self-reported mobility or ADL disability at baseline...

Aims: Anomalous origin of a coronary artery from the opposite sinus (ACAOS) has been associated with adverse cardiac events in the young. It remains unknown whether this holds true for middle-aged patients with uncorrected ACAOS as well. We assessed the outcome in middle-aged patients with newly diagnosed ACAOS by coronary computed tomography angiography (CCTA) compared with a matched cohort. Methods and results: We retrospectively identified 68 consecutive patients with ACAOS documented by CCTA...

We investigated the prevalence and correlates of prefrailty/frailty, determined on the basis of the Fried criteria, in Chinese patients with and those without human immunodeficiency virus (HIV) infection. HIV-infected patients were more likely to be frail or prefrail than controls, and this association remained significant after adjustment for potential confounders (odds ratio, 3.79). After additional adjustment for neurocognitive impairment and depressive and insomnia symptoms, this association remained significant but attenuated (odds ratio, 2...

Spontaneous haemothorax is a subcategory of haemothorax that occurs in the absence of trauma or other causes. It is a rare emergency that can progress rapidly with massive blood loss leading to haemorrhagic shock and death. We describe a patient with massive spontaneous haemothorax caused by the disruption of an oesophageal artery from the middle segment of descending thoracic aorta. We sutured the bleeding artery in an emergency thoracotomy after the failure of interventional procedure.
