Diabetes: A Multifaceted Disorder

Diabetes is a chronic disease associated with increased morbidity and mortality from cardiovascular diseases cancer, chronic obstructive pulmonary disease, and kidney or liver disease. Despite the fact that aging is the main risk factor for the onset and progressionof type 2 diabetes mellitus (the most common type of diabetes), in recent decades, age-standardized all-cause mortality in the population with type 2 diabetes has fallen morethan in the general population. However, age-specific data indicate that this trend in the total diabetes population is predominantly influenced by trends in those aged 80 or more years. The figures observed in those younger than 80 years indicate that improvements in the management of diabetes and its complications may not have translated into a direct prevention of premature deaths related to type 2 diabetes

Type 2 diabetes mellitus and COVID-19: a narrative review

Type-2 diabetes mellitus (T2DM) is a chronic metabolic disorder. The incidence and prevalence of patients with T2DM are increasing worldwide, even reaching epidemic values in most high- and middle-income countries. T2DM could be a risk factor of developing complications in other diseases. Indeed, some studies suggest a bidirectional interaction between T2DM and COVID-19. A growing body of evidence shows that COVID-19 prognosis in individuals with T2DM is worse compared with those without. Moreover, various studies have reported the emergence of newly diagnosed patients with T2DM after SARS-CoV-2 infection. The most common treatments for T2DM may influence SARS-CoV-2 and their implication in infection is briefly discussed in this review. A better understanding of the link between TD2M and COVID-19 could proactively identify risk factors and, as a result, develop strategies to improve the prognosis for these patients

A comparative human rights analysis of laws and policies for adolescent contraception in Uganda and Kenya

BACKGROUND: Improving access to adolescent contraception information and services is essential to reduce unplanned adolescent pregnancies and maternal mortality in Uganda and Kenya, and attain the SDGs on health and gender equality. This research studies to what degree national laws and policies for adolescent contraception in Uganda and Kenya are consistent with WHO standards and human rights law. METHODS: This is a comparative content analysis of law and policy documents in force between 2010 and 2018 governing adolescent (age 10–19 years) contraception. Between and within country differences were analysed using WHO’s guidelines “Ensuring human rights in the provision of contraceptive information and services”. RESULTS: Of the 93 laws and policies screened, 26 documents were included (13 policies in Uganda, 13 policies in Kenya). Ugandan policies include a median of 1 WHO recommendation for adolescent contraception per policy (range 0–4) that most frequently concerns contraception accessibility. Ugandan policies have 6/9 WHO recommendations (14/24 sub-recommendations) and miss entirely WHO’s recommendations for adolescent contraception availability, quality, and accountability. On the other hand, most Kenyan policies consistently address multiple WHO recommendations (median 2 recommendations/policy, range 0–6), most frequently for contraception availability and accessibility for adolescents. Kenyan policies cover 8/9 WHO recommendations (16/24 sub-recommendations) except for accountability. CONCLUSIONS: The current policy landscapes for adolescent contraception in Uganda and Kenya include important references to human rights and evidence-based practice (in WHO’s recommendations); however, there is still room for improvement. Aligning national laws and policies with WHO’s recommendations on contraceptive information and services for adolescents may support interventions to improve health outcomes, provided these frameworks are effectively implemented.

Hepatitis C antibody prevalence and active hepatitis C infection in HIV-negative gay, bisexual, and other men who have sex with men in Barcelona and Madrid, Spain (March 2018-March 2021)

Objectives: Hepatitis C virus (HCV) has been recognized as a sexually transmitted infection (STI) in HIV-positive men who have sex with men (MSM), with an increased notification in HIV-negative MSM. The aim of this study was to determine the prevalence of HCV antibody and active HCV infection in HIV-negative gay, bisexual, and other MSM (GBMSM), and their characteristics, in Barcelona and Madrid, from March 2018 to March 2021. Methods: Cross-sectional study conducted on 3548 HIV-undiagnosed GBMSM, across four HIV/STI testing centers. Respondents submitted an online, self-administered questionnaire after consultation, which collected information on sociodemographics, sexual health history, HCV knowledge, and substance consumption. Prevalence of HCV antibodies was determined by a reactive result in a rapid anti-HCV test or enzyme-linked immunosorbent assay (ELISA), while active HCV infection was determined by participants who were also positive on an HCV-RNA test. Crude and adjusted Poisson analyses with robust variance are presented for both prevalence and active infection. Results: In total, 97.6% of participants (n = 3463) were HIV-negative. Of those, 18 were found to have HCV antibodies (0.52%), of which nine (0.26%) were also HCV-RNA positive. Those with HCV antibodies were associated to have lived with an HCV (+) person (adjusted prevalence ratio [APR]: 7.84, [95% confidence interval: 2.50-24.53]), using injectable drugs for sex (APR: 6.92, [1.20-39.79]) and testing positive for an STI in the previous year (APR: 4.06, [1.09-15.12]). Presenting an active infection was strongly associated with a previous HCV diagnosis (APR: 100.82 [22.16-458.76]), sexualized injectable drug use (APR: 17.53 [2.70-113.76]), and sharing douching material (APR: 7.45, [2.12-25.95]). Conclusion: Sexual practices with a higher risk of bleeding and sexualized drug use, particularly sexualized injectable drug use, were associated with higher rates of HCV diagnosis in GBMSM. Identifying these practices during consultation, contact tracing new cases and regularly testing those with a previous history of HCV, will facilitate HCV eradication.Both a Health Research Grant (Fondo de Investigación en Salud, FIS P117/02077) and an Intramural Strategy Action Grant (PI17CIII/00037), From the Carlos III Institute, at the Science and Innovation Ministry of the Spain Government, supported this study.S

In batch, the use of industrially-preferable solvents was investigated, with dimethyl carbonate proving to be most generally-applicable. Significantly, the HyperBTM-derived immobilised catalysts were readily recycled, with no loss in either activity or selectivity. In addition to the kinetic resolution of secondary benzylic, propargylic, allylic and cycloalkanol derivatives, a range of 21 tertiary heterocyclic alcohols, based on privileged 3-hydroxyoxindole and 3-hydroxypyrrolidinone substructures, were resolved with up to excellent selectivity (s = 7–190). Finally, the immobilised isothiourea catalysts were applied in a packed bed reactor to demonstrate the first example of the kinetic resolution of tertiary heterocyclic alcohols in a continuous flow process. High selectivities were obtained for the resolution of 3-hydroxyoxindole derivatives in ethyl acetate (s up to 70); and for 3-hydroxypyrrolidinones derivatives in toluene (s up to 42).PostprintPeer reviewe

How did COVID-19 measures impact sexual behaviour and access to HIV/STI services in Panama? Results from a national cross-sectional online survey.

OBJECTIVE: To describe reported changes in sexual behaviours, including virtual sex (sexting and cybersex), and access to HIV/STI testing and care during COVID-19 measures in Panama. METHODS: We conducted an online cross-sectional survey from 8 August to 12 September 2020 among adults (≥18 years) residing in Panama. Participants were recruited through social media. Questions included demographics, access to HIV/STI testing and HIV care, and sexual behaviours 3 months before COVID-19 social distancing measures and during social distancing measures (COVID-19 measures). Logistic regression was used to identify associations between variables and behavioural changes. RESULTS: We recruited 960 participants; 526 (54.8%) identified as cis-women, 366 (38.1%) cis-men and 68 (7.1%) non-binary or another gender. The median age was 28 years (IQR: 23-37 years), and 531 of 957 (55.5%) were of mixed ethnicity (mixed Indigenous/European/Afro-descendant ancestry). Before COVID-19 measures, virtual sex was reported by 38.5% (181 of 470) of cis-women, 58.4% (184 of 315) cis-men and 45.0% (27 of 60) non-binary participants. During COVID-19 measures, virtual sex increased among 17.2% of cis-women, 24.7% cis-men and 8.9% non-binary participants. During COVID-19 measures, 230 of 800 (28.8%) participants reported decreased casual sex compared with pre-COVID-19 measures. Compared with pre-COVID-19 measures, decreased casual sex was reported more frequently during COVID-19 measures by cis-men compared with cis-women (39.2% vs 22.9%, urban/rural adjusted OR (AOR)=2.17, 95% CI 1.57 to 3.01), and by Afro-descendant compared with participants of mixed ethnicity (40.0% vs 29.8%, AOR=1.78, 95% CI 1.07 to 2.94). Compared with no change in virtual sex (16.8%), increased virtual sex (38.5%, AOR=1.78, 95% CI 1.10 to 2.88) and decreased virtual sex (86.7%, AOR=16.53, 95% CI 7.74 to 35.27) were associated with decreased casual sex encounters. During COVID-19 measures, HIV/STI testing could not be obtained by 58.0% (58 of 100) of the participants who needed a test, and interrupted HIV care was reported by 53.3% (8 of 15) of participants living with HIV. CONCLUSIONS: COVID-19 measures in Panama were associated with a decrease in casual sex among cis-men and Afro-descendant people, while access to HIV/STI testing and care was seriously disrupted

Atherosclerosis, Cardiovascular Disease, and COVID-19: A Narrative Review

Atherosclerosis is a chronic inflammatory and degenerative process that mainly occurs in large- and medium-sized arteries and is morphologically characterized by asymmetric focal thickenings of the innermost layer of the artery, the intima. This process is the basis of cardiovascular diseases (CVDs), the most common cause of death worldwide. Some studies suggest a bidirectional link between atherosclerosis and the consequent CVD with COVID-19. The aims of this narrative review are (1) to provide an overview of the most recent studies that point out a bidirectional relation between COVID-19 and atherosclerosis and (2) to summarize the impact of cardiovascular drugs on COVID-19 outcomes. A growing body of evidence shows that COVID-19 prognosis in individuals with CVD is worse compared with those without. Moreover, various studies have reported the emergence of newly diagnosed patients with CVD after COVID-19. The most common treatments for CVD may influence COVID-19 outcomes. Thus, their implication in the infection process is briefly discussed in this review. A better understanding of the link among atherosclerosis, CVD, and COVID-19 could proactively identify risk factors and, as a result, develop strategies to improve the prognosis for these patients

Highly Functionalized Biaryls via Suzuki-Miyaura Cross-Coupling Catalyzed by Pd@MOF under Batch and Continuous Flow Regimes

A diverse set of more than 40 highly functionalized biaryls was synthesized successfully through the Suzuki-Miyaura cross-coupling reaction catalyzed by Pd nanoparticles supported in a functionalized mesoporous MOF (8 wt% Pd@MIL-101(Cr)-NH2). This could be achieved under some of the mildest conditions reported to date and a strong control over the leaching of metallic species could be maintained, despite the presence of diverse functional groups and/or several heteroatoms. Some of the targeted molecules are important intermediates in the synthesis of pharmaceuticals and we clearly exemplify the versatility of this catalytic system, which affords better yields than currently existing commercial procedures. Most importantly, Pd@MIL-101-NH2 was packed in a micro-flow reactor, which represents the first report of metallic nanoparticles supported on MOFs employed in flow chemistry for catalytic applications. A small library of 11 isolated compounds was created in a continuous experiment without replacing the catalyst, demonstrating the potential of the catalyst for large-scale applications.AuthorCount:8;</p
