BackgroundHighly active antiretroviral therapy improves the longevity of patients living with HIV/AIDS. We conducted the study in order to assess health related quality of life of HIV/AIDS patients and the association of socio-demographic and disease related variables with health related quality of life.MethodsHealth facility based cross-sectional study among 400 HIV/AIDS patients taking highly active anti-retroviral therapy from Gondar University referral hospital was conducted. A pre-tested semi-structured questionnaire, which was adopted from World Health Organization Quality of life brief instrument, was used. The data were then analyzed using SPSS version 20 software for Windows.ResultsThe majority of the respondents reported to to have a good physical health (15.55). The World Health Organization clinical stage was found to be significantly associated with all the domains of health related quality of life. The current acute illness condition of the respondents, however, did not show significant association with any of the domains of health related quality of life.ConclusionsThe six domains of health related quality of life were found to be moderate. The physical health and spirituality of the patients were relatively higher than their social relationship. Sex, age, educational status, residence and marital status showed significant association with at least one domain of health related quality of life.

Chimeric antigen receptor (CAR) T-cell therapy is a novel, customized immunotherapy that is considered a ‘living’ and self-replicating drug to treat cancer, sometimes resulting in a complete cure. CAR T-cells are manufactured through genetic engineering of T-cells by equipping them with CARs to detect and target antigen-expressing cancer cells. CAR is designed to have an ectodomain extracellularly, a transmembrane domain spanning the cell membrane, and an endodomain intracellularly. Since its first discovery, the CAR structure has evolved greatly, from the first generation to the fifth generation, to offer new therapeutic alternatives for cancer patients. This treatment has achieved long-term and curative therapeutic efficacy in multiple blood malignancies that nowadays profoundly change the treatment landscape of lymphoma, leukemia, and multiple myeloma. But CART-cell therapy is associated with several hurdles, such as limited therapeutic efficacy, little effect on solid tumors, adverse effects, expensive cost, and feasibility issues, hindering its broader implications.

Whether a small GTPase RhoA plays a role in the pathology of abdominal aortic aneurysm (AAA) has not been determined. We show here that RhoA expression is reduced in human AAA lesions, compared with normal areas. Furthermore, incidence of AAA formation is increased in vascular smooth muscle cell (VSMC)-specific RhoA conditional knockout (cKO) mice. The contractility of the aortic rings and VSMCs from RhoA cKO mice is reduced, and expression of genes related to the VSMC contractility is attenuated by loss of RhoA. RhoA depletion activates the mitogen-activated protein (MAP) kinase signaling, including MAP4K4, in the aorta and VSMCs. Inhibition of MAP4K4 activity by DMX-5804 decreases AAA formation. Set, a binding protein to active RhoA, functions as an activator of MAP4K4 by sequestering PP2A, an inhibitor of MAP4K4, in the absence of RhoA. In conclusion, RhoA counteracts AAA formation through inhibition of MAP4K4 in cooperation with Set.

Background Metformin is the first-line drug in the treatment of type 2 diabetes mellitus. Monitoring vitamin B 12 deficiency associated with long-term and high-dose therapy is not a common practice in many clinical settings in Ethiopia. Objective The study aimed to measure levels of serum vitamin B 12 and folate and to assess the macrocytic status of type 2 diabetes mellitus patients on metformin. Methods A cross-sectional study was conducted on 80 type 2 diabetes mellitus patients who had been on metformin for 5 months or more at the diabetic clinic of Tikur Anbessa Specialized Teaching Hospital. Serum vitamin B 12 and folate levels were quantified by chemiluminescent immunoassays. Mean corpuscular volume was determined by complete blood count. Differences in vitamin B 12 and folate levels and mean corpuscular volume between different groups were assessed using Kruskal–Wallis H and Mann–Whitney U tests. Results Vitamin B 12 and folate deficiency were documented in 5% and 23.8% of participants, respectively, and 6.2% of patients were macrocytic. Levels of vitamin B 12 and folate in patients who had been on metformin >1,500 mg/day ≥4 years were significantly lower those who had been on metformin 1,000–1,500 mg/day and <1,000 mg/day <4 years, respectively. Conclusion Low serum vitamin B 12 and folate levels and macrocytosis were found to be associated with prolonged metformin treatment.

ObjectiveThis study aimed to assess the prevalence and determinants of musculoskeletal disorders (MSDs) among patients with diabetes in southern Ethiopia.DesignFacility-based cross-sectional study.SettingData collected from 1 March 2021 to 30 August 2021 at Arba Minch General Hospital.ParticipantsThree hundred and sixty-five patients with diabetes attending care at Arba Minch General Hospital.Main outcome measuresThe magnitude and determinants of the MSDs.ResultsThe prevalence of MSDs among patients with diabetes was 23.29% (95% CI 19.00 to 27.76). The likelihood of developing MSDs was 6.8 times higher among women than men (AOR=6.787, 95% CI 2.08 to 22.19). Rural participants were about 2.4 times (AOR=2.38, 95% CI 1.06 to 5.33) more likely to develop MSDs as compared with urban participants. Participants aged >50 years were 5.9 times more likely to develop MSDs as compared with those aged ≤50 years (AOR=5.864, 95% CI 2.663 to 12.914). The odds of developing MSDs was 6.2 times (AOR=6.247, 95% CI 1.158 to 33.702) and 5.5 times (AOR=5.451 95% CI 1.174 to 25.312) higher among participants who attended primary and secondary education as compared with those who attended college and above, respectively. Participants with cardiovascular disease were 3.9 times more likely to develop MSDs as compared with their counterparts (AOR=3.854, 95% CI 1.843 to 8.063).ConclusionsThis study showed that age, sex, educational status, place of residence and cardiovascular disease were found to be determinants of MSDs. Thus, clinical and public health interventions working on diabetes mellitus should consider these determinants.
