OBJECTIVE: This review aims to identify the evidence base for the consequences of over and undertreatment of type 2 diabetes mellitus in a frail population.
METHODS: In this systematic review, we searched MEDLINE, Embase, PubMed, CINAHL and the Cochrane Library for studies from January 2001 to 15th August 2022. We included a variety of study types that assessed and reported frailty including patients ≥18 years old. Studies included those that reported the prevalence of over or undertreatment of diabetes mellitus in a frail population and those examining outcomes related to glucose control in frail older people living with diabetes. Data were extracted using a bespoke extraction table using a narrative synthesis approach.
RESULTS: A total of 4114 articles were identified with 112 meeting inclusion criteria. These included 15,130 participants across the 11 studies with sample sizes ranging from 101 to 11,140. Several areas were identified in the included studies where under or overtreatment of diabetes impacted outcomes for patients. These included hospital admissions, readmissions, length of stay, falls, mortality, cognitive impairment and cardiovascular disease outcomes.
CONCLUSIONS: The results showed that there was a high heterogeneity of outcomes between the studies and that many examined small numbers of participants. In this review, both over and undertreatment were shown to increase adverse outcomes in frail older people. Further research around optimal glycaemic control for frail older people living with diabetes is required with the aim to identify ideal target ranges and produce practical clinical guidelines to promote attainment of these.

Aim: To assess rates of no systemic treatment (NST), attrition across lines of therapy, and factors influencing treatment selection in patients with locally advanced or metastatic urothelial cancer (la/mUC). Methods: Systematic literature review to identify real-world studies reporting NST or attrition rates in la/mUC from 2017-2022 (including data reported since 2015). Results: Of 2439 publications screened, 29 reported NST rates, ranging from 40-74% in eight European-based studies, 14-60% in 12 US-based studies, and 9-63% in nine studies in other locations (meta-analysis estimate, 39%). Factors associated with NST or no second-line therapy included older age, female sex, poor performance status, poor renal function and distant metastases. Conclusion: A substantial proportion of patients with la/mUC do not receive guideline-recommended treatment.
A review of how patients with bladder cancer are treated or not treated with anti-cancer drugsPeople with advanced bladder cancer have a short survival. Bladder cancer is called advanced when it has spread outside of the urinary tract. Several drug treatments are available for people with advanced bladder cancer. However, sometimes people do not receive any drug treatment. We looked at published studies to see how many people with advanced bladder cancer did not receive any drug treatment and the reasons why. We also looked at how long people lived with or without drug treatment. We found that many people with advanced bladder cancer did not receive drug treatment. The number of people who received no drug treatment varied in studies from different countries. People who were older, were female, had poor health or kidney problems, or had cancer that had spread to other parts of the body were less likely to receive drug treatment. People who did not receive drug treatment lived for an average of 2 to 7 months, compared with 9 to 35 months for people who received drug treatment. More studies are needed to investigate the reasons why drug treatment is sometimes not used in people with advanced bladder cancer who could receive treatment, so that more people can benefit from available treatments.

To investigate the prevalence, outcomes, and factors associated with potential glycemic overtreatment and undertreatment of type 2 diabetes mellitus (T2DM) in long-term care facilities (LTCFs).
Systematic review.
Residents with T2DM and aged ≥60 years living in LTCFs.
Articles published between January 2000 and September 2020 were retrieved following a systematic search of MEDLINE, EMBASE, Cochrane Library, CINAHL plus, and gray literature. Inclusion criteria were the reporting of (1) potential overtreatment and undertreatment quantitatively defined (implicitly or explicitly) based on hemoglobin A1c (HbA1c) and/or blood glucose; (2) prevalence, outcomes, and associated factors of potential glycemic overtreatment and undertreatment; and (3) the study involved residents of LTCFs.
Fifteen studies were included. Prevalence of potential overtreatment (5%-86%, n = 15 studies) and undertreatment (1.4%-35%, n = 8 studies) varied widely among facilities and geographical locations, and according to definitions used. Prevalence of potential overtreatment was 16%-74% when defined as treatment with a glucose-lowering medication in a resident with ≥1 hypoglycemia risk factor or serious comorbidity, together with a HbA1c <7% (n = 10 studies). Potential undertreatment was commonly defined as residents on glucose-lowering medication having HbA1c >8.5% and the prevalence 1.4%-14.8% (n = 6 studies). No studies prospectively measured resident health outcomes from overtreatment and undertreatment. Potential overtreatment was positively associated with use of oral glucose-lowering medications, dementia diagnosis or dementia severity, and/or need for assistance with activities of daily living (n = 2 studies). Negative association was found between potential overtreatment and use of insulin/combined insulin and oral glucose-lowering medication. No studies reported factors associated with potential undertreatment.
The prevalence of potential glycemic overtreatment and undertreatment varied widely among residents with T2DM depending on the definition(s) used in each study. Longitudinal studies examining associations between glycemic management and health outcomes, and the use of consensus definitions of overtreatment and undertreatment are required to establish findings about actual glycemic overtreatment and undertreatment in LTCFs.

Risk of breast cancer increases with age and very few data are available in patients older than 89.
A retrospective analysis on patients aged 89 and older treated between 2008 and 2019 at our certified breast center. The aim was to analyze clinical characteristics, decision-making, treatment, outcomes and open questions regarding this subpopulation for which there is a lack of guidelines.
58 patients included. Tumor characteristics were analyzed, 85% patients underwent surgery of which 44% had a mastectomy. The median follow-up and overall survival were 20 and 76 months, respectively.The median survival of metastatic and non-metastatic patients were 14 and 50 months, respectively. Most patients did not receive any adjuvant treatment and among these 14% had a relapse.
Elderly patients should not be under or over-treated because of their age; they represent a large heterogeneous group deserving a sub-stratification for a better tailored treatment.

In the 3 decades since Liebowitz\'s review of \'a neglected anxiety disorder,\' controversy and challenges have remained in the study of social anxiety disorder (SAD). This review examines evidence around the classification and subtyping of SAD, focusing on generalized SAD. Substantial discrepancies and variation in definition, epidemiology, assessment, and treatment of generalized SAD exist as the international literature on it has grown. In East Asian cultures in particular, study of taijin kyofusho has been important to a broadened conceptualization of SAD into generalized SAD. Despite important progress with biological and other studies, many challenges in the understanding of generalized SAD will remain in the years to come.
