Sarcopenia and Appendicular Muscle Mass as Predictors of Impaired Fasting Glucose/Type 2 Diabetes in Elderly Women

Elderly women exhibit a high risk of type 2 diabetes (T2D), but no definitive data exist about the possible role of postmenopausal increases in visceral adiposity, the loss of lean body mass, or decreases in the sum of the lean mass of arms and legs (appendicular skeletal muscle mass (ASMM)). This retrospective, longitudinal study investigated whether body composition (bioelectrical impedance analysis) predicted the development of impaired fasting glucose (IFG) or T2D in a cohort of 159 elderly women (age: 71 ± 5 years, follow-up: 94 months) from southern Italy (Clinical Nutrition and Geriatric Units of the “Mater Domini” University Hospital in Catanzaro, Calabria region, and the “P. Giaccone ”University Hospital in Palermo, Sicily region). Sarcopenia was defined in a subgroup of 128 women according to the EWGSOP criteria as the presence of low muscle strength (handgrip strength <16 kg) plus low muscle mass (reported as appendicular skeletal muscle mass <15 kg). Participants with a low ASMM had a higher IFG/T2D incidence than those with a normal ASMM (17% vs. 6%, p-adjusted = 0.044); this finding was independent of BMI, fat mass, waist circumference, and habitual fat intake (OR = 3.81, p = 0.034). A higher incidence of IFG/T2D was observed in the subgroup with sarcopenia than those without sarcopenia (33% vs. 7%, p-adjusted = 0.005) independent of BMI and fat mass (OR = 6.75, p = 0.007). In conclusion, this study demonstrates that elderly women with low ASMM had a higher probability of developing IFG/T2D. Further studies are needed to confirm these results in men and in other age groups.

Being on hemodialysis during the COVID‐19 outbreak: A mixed‐methods’ study exploring the impacts on dialysis adequacy,analytical data,and patients’ experiences

For individuals with end‐stage renal disease (ESRD), the novel coronavirus can present several additional challenges in disease self‐management. This study aimed to explore the impacts of the COVID‐19 pandemic in non‐COVID‐19 patients with ESRD undergoing in‐center hemodialysis (HD). A mixed‐methods study was conducted with a purposive sample recruited from one dialysis unit in Portugal. Quantitative data were collected retrospectively from patients' medical records from February 2020 (T1—before the outbreak) and from April 2020 (T2—during lockdown). Semi‐structured interviews were conducted with 20 patients (66.9 ± 11.9 years old) undergoing HD for an average of 46.1 months (±39.5) in April 2020. Overall results suggested that dialysis adequacy and serum albumin levels decreased significantly at T2, while phosphorus levels increased. The findings from thematic analysis suggested several psychosocial negative impacts and impacts on disease and treatment‐related health behaviors (eg, difficulties managing dietary restrictions during the lockdown and diminished physical activity), which can partially explain these quantitative results. However, some patients were also able to find positive impacts in this experience and problem‐focused and emotional strategies were identified to cope with the demands of COVID‐19. Several recommendations have been made to mitigate patients’ emotional, relational, and educational unmet needs during the current pandemic and in the event of new outbreaks.

BCG infection (BCGitis) following intravesical instillation for bladder cancer and time interval between treatment and presentation: A systematic review

Objective: Intravesical Bacillus Calmette-Guèrin (BCG) is an effective treatment in non––muscle-invasive bladder cancer, however, extravesical BCG infection may occur in remote organs as a potentially serious complication. Researchers aimed to assess whether a different timing of BCG infection after intravesical administration of BCG could be identified and estimated for each single involved organ. Methods: We performed a systematic literature review over systemic and genitourinary BCG infection case reports, including 271 published case reports for a total of 307 patients. Demographic data, clinical features, and timing of BCG infection development were collected and analyzed for each patient. Results: BCG infection developed with a different timing from last instillation, depending on the involved organ. Among the genitourinary complications, penile lesions occurred as early as 1 (1;3) weeks, while orchiepididymitis occurred as late as 56 (6.25;156) weeks. At the same time, granulomatous hepatitis and lungs involvement such as miliary pulmonary BCG infection occurred earlier, with a median time of 1 (1;4) and 1 (1;6) weeks respectively, whereas vascular, osteoarticular, and muscular complications developed with a median timing from last instillation of 52 (20;104), 68 (14;156), and 93 (29;156) weeks, respectively. The analysis detected a cluster between lungs, liver, and bone marrow complications on one side and muscular and osteoarticular or vascular complications on the other side was also observed. Conclusions: BCG infection after intravesical BCG for bladder cancer may develop even several months or years after the last instillation, depending on the involved organs. When BCG infection interests one or more organ, 2 main associative patterns are common: one involving lungs, liver, and bone marrow, with earlier occurrence but lower rates of microbiological diagnosis achievement, and one involving muscular and osteoarticular or vascular districts, with later occurrence but higher rates of microbiological evidence.     

Narrative review of prostate cancer grading systems: will the Gleason scores be replaced by the Grade Groups?

The Gleason grading system, proposed by Dr. Donald F. Gleason in 1966, is one of the most important prognostic factors in men with prostate cancer (PCa). At consensus conferences held in 2005 and 2014, organized by the International Society of Urological Pathology (ISUP), the system was modified to reflect the current diagnostic and therapeutic approaches. In particular, in the 2014 Conference, it was recognized that there were weaknesses with the original and the 2005 ISUP modified Gleason systems. Based on the results of a research conducted by Prof. JI Epstein and his group, a new grading system was proposed by the ISUP in order to address some of such deficiencies: i.e., the five distinct Grade Groups (GGs). Since 2014, results of studies have been published by different groups and societies, including the Genitourinary Pathology Society (GUPS), giving additional support to the prognostic role of the architectural Gleason patterns and, in particular, of the GGs. A revised GG system, taking into account the percentage of Gleason pattern (GP) 4, cribriform and intraductal carcinoma, tertiary GP 5, and reactive stroma grade, has shown to have some advantages, however not ready for adoption in the current practice. The aim of this contribution was to review the major updates and recommendations regarding the GPs and GSs, as well as the GGs, trying to give an answer to the following questions: “How has the grade group system been used in the routine?” and “will the Gleason scoring system be replace by the grade groups?” We also discussed the potential implementation in the future of molecular pathology and artificial intelligence in grading to further define risk groups in patients with PCa.     

Healthcare Workers’ (HCWs) attitudes towards mandatory influenza vaccination: A systematic review and meta-analysis

Influenza is a disease responsible for thousands of deaths every year. Although healthcare workers (HCWs) represent a way of contagion for patients, vaccination coverage among them is low. Mandatory vaccination has been proposed, but controversies remain. This systematic review and meta-analysis aimed to assess the acceptance of mandatory vaccination by HCWs, and to investigate associated characteristics. MEDLINE, Scopus, Embase, PsycInfo, CINAHL and Web of Science were used to search for studies assessing the topic. PRISMA statements were followed. Of the 13,457 univocal records found, 52 studies were included in the systematic review and 40 in the meta-analysis. The pooled proportion of HCWs accepting the policy was of 61% (95% CI: 53%- 68%) but with great heterogeneity between continents (from 54% in Europe to 69% in Asia) and in different professionals (from 40% in nurses to 80% in students). Vaccinated HCWs agreed more frequently with mandatory vaccination than non-vaccinated ones. More studies that consider mandatory vaccination acceptance as the main outcome are needed, but the results of this study confirm that in some settings the majority of HCWs favour mandatory vaccination. This, combined with effects that a flu epidemic could have if overlapped to pandemics with similar symptoms, requires renewed considerations on mandatory vaccination.
