A Narrative Review of Retinopathy in Diabetic Patients.
Gupta, S, Thool, AR
Cureus. 2024;(1):e52308
Abstract
Patients with diabetes may be at risk of ocular diseases, like retinopathy due to diabetes and oedema of the eye. Patients with retinopathy due to diabetes experience constant injury to the retina and the posterior end of the eye, which is light-sensitive. It is a prominent complication faced by diabetics that threatens a patient's vision. Diabetes can inhibit the body's potential to ingest and maintain blood glycemic levels, resulting in several health problems. Excessive glucose in the blood can affect the eyes and other organs of the body. Diabetes has an effect on the blood supply system of the retina over a prolonged period of time. Diabetes-related retinopathy can lead to blindness as fluid can flow into the macula, which is essential for maintaining a clear visual field. The macula, despite its small size, is the region that enables us to comprehend colours and fine peculiarities well. The fluid swells the macula, leading to an impaired visual field. The weak, irregular blood vessels formed during neovascularization can potentially haemorrhage into the posterior end of the eye, obstructing the visual field. Blood vessels of the eye leak blood and other fluids, causing retinal tissue enlargement and eyesight clouding. Typically, the illness affects both eyes. Diabetes retinopathy is more likely to develop as a person's diabetes progresses. If untreated, retinopathy due to diabetes can result in blindness.

Abstract
BACKGROUND Muscle mass is important for metastatic prostate cancer survival and quality of life (QoL). The backbone of treatment for men with metastatic castration sensitive prostate cancer (mCSPC) is androgen deprivation therapy (ADT) with an androgen signaling inhibitor. ADT is an effective cancer treatment, but it facilitates significant declines in muscle mass and adverse health outcomes important to mCSPC survivors, such as fatigue, and reductions in physical function, independence, insulin sensitivity, and QoL. In non-metastatic CSPC survivors, resistance training (RT) preserves muscle mass and improves these related health outcomes, but the biggest barrier to RT in CSPC survivors of all stages is fatigue. Creatine monohydrate supplementation coupled with RT (Cr + RT) may address this barrier since creatine plays a critical role in energy metabolism. Cr + RT in cancer-free older adults and other clinical populations improves muscle mass and related health outcomes. Evidence also suggests that creatine supplementation can complement cancer treatment. Thus, Cr + RT is a strategy that addresses gaps in survivorship needs of people with mCSPC. The purpose of this parallel, double-blind randomized controlled trial is to test the effects of 52-weeks of Cr + RT compared with placebo (PLA) and RT (PLA + RT) on muscle mass, other related health outcomes, and markers of cancer progression. METHODS We will carry out this trial with our team's established, effective, home-based, telehealth RT program in 200 mCSPC survivors receiving ADT, and evaluate outcomes at baseline, 24-, and 52-weeks. RT will occur twice weekly with elastic resistance bands, and an established creatine supplementation protocol will be used for supplementation delivery. Our approach addresses a major facilitator to RT in mCSPC survivors, a home-based RT program, while utilizing a supervised model for safety. DISCUSSION Findings will improve delivery of comprehensive survivorship care by providing a multicomponent, patient-centered lifestyle strategy to preserve muscle mass, improve health outcomes, and complement cancer treatment (NCT06112990).

Abstract
Colorectal cancer (CRC) epidemiology is changing due to a birth cohort effect, first recognized by increasing incidence of early onset CRC (EOCRC, age <50 years). In this paper, we define "birth cohort CRC" as the observed phenomenon, among individuals born 1960 and later, of increasing CRC risk across successive birth cohorts, rising EOCRC incidence, increasing incidence among individuals aged 50 to 54 years, and flattening of prior decreasing incidence among individuals aged 55 to 74 years. We demonstrate birth cohort CRC is associated with unique features, including increasing rectal cancer (greater than colon) and distant (greater than local) stage CRC diagnosis, and increasing EOCRC across all racial/ethnic groups. We review potential risk factors, etiologies, and mechanisms for birth cohort CRC, using EOCRC as a starting point and describing importance of viewing these through the lens of birth cohort. We also outline implications of birth cohort CRC for epidemiologic and translational research, as well as current clinical practice. We postulate that recognition of birth cohort CRC as an entity-including and extending beyond rising EOCRC-can advance understanding of risk factors, etiologies, and mechanisms, and address the public health consequences of changing CRC epidemiology.

Abstract
BACKGROUND Bone biomarkers are strongly prognostic for overall survival (OS) in men with castration-resistant prostate cancer but not fully established for hormone-sensitive prostate cancer (HSPC). OBJECTIVE Bone biomarkers in HSPC were prospectively evaluated as part of a phase 3 study of androgen deprivation therapy ± the CYP17 inhibitor orteronel. DESIGN, SETTING, AND PARTICIPANTS Patients were randomly divided into training (n = 316) and validation (n = 633) sets. Recursive partitioning and Cox proportional hazard models were employed. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS Bone resorption (C-telopeptide and pyridinoline) and bone formation markers (C-terminal collagen propeptide and bone alkaline phosphatase) were assessed from patient sera. RESULTS AND LIMITATIONS Of 1279 men, 949 had evaluable baseline bone biomarkers. Optimal cutoffs were identified to define elevated levels of each of the four biomarkers (all p < 0.05) that were associated with worse OS. After adjusting for clinical risk factors in the validation set, elevated bone biomarkers were statistically significantly associated with an increased risk of death (hazard ratios ranging from 1.37 to 1.92). Recursive partitioning algorithms applied to the training set identified three risk groups (low, intermediate, and poor) with differential OS outcomes (median OS: 8.2, 5.1, and 2.1 yr, respectively) based on combinations of bone biomarkers. These results were confirmed in the validation set. CONCLUSIONS In men with HSPC initiating androgen deprivation therapy, bone biomarkers are strongly and independently prognostic for OS. Bone biomarker levels alone or in combination with clinical covariates identify unique subsets of men with differential OS outcomes. These results validate the clinical value of bone biomarker assessment in the HSPC state, extending bone biomarker utility beyond the castration-resistant state. PATIENT SUMMARY In men with newly diagnosed metastatic prostate cancer, high levels of bone turnover biomarkers are associated with a shorter lifespan.

Abdelrahman, K, Shiyovich, A, Huck, DM, Berman, AN, Weber, B, Gupta, S, Cardoso, R, Blankstein, R
Diagnostics (Basel, Switzerland). 2024;(2)
Abstract
Coronary artery calcium (CAC) is a marker of coronary atherosclerosis, and the presence and severity of CAC have been shown to be powerful predictors of future cardiovascular events. Due to its value in risk discrimination and reclassification beyond traditional risk factors, CAC has been supported by recent guidelines, particularly for the purposes of informing shared decision-making regarding the use of preventive therapies. In addition to dedicated ECG-gated CAC scans, the presence and severity of CAC can also be accurately estimated on non-contrast chest computed tomography scans performed for other clinical indications. However, the presence of such "incidental" CAC is rarely reported. Advances in artificial intelligence have now enabled automatic CAC scoring for both cardiac and non-cardiac CT scans. Various AI approaches, from rule-based models to machine learning algorithms and deep learning, have been applied to automate CAC scoring. Convolutional neural networks, a deep learning technique, have had the most successful approach, with high agreement with manual scoring demonstrated in multiple studies. Such automated CAC measurements may enable wider and more accurate detection of CAC from non-gated CT studies, thus improving the efficiency of healthcare systems to identify and treat previously undiagnosed coronary artery disease.

Are People With Type 1 Diabetes Mellitus Appropriately Following Insulin Injection Technique Practices: A Review of Literature.
Gupta, S, Ramteke, H, Gupta, S, Gupta, S, Gupta, KS
Cureus. 2024;(1):e51494
Abstract
People with type 1 diabetes mellitus (T1DM) need to take multiple doses of insulin injections daily throughout their lives. However, a notable portion of people with diabetes mellitus (DM) show suboptimal insulin injection technique practices. They are supposed to follow the recommended insulin injection technique guidelines. Our explorative literature search, including studies from the past 30 years, is expected to identify the deficiencies of self-injection insulin techniques and the associated complications in people with T1DM, where we have summarised the overall incidence of complications that have occurred due to nonadherence of the prescribed guidelines, along with their associated risk factors. We have attempted to include multiple systematic reviews, meta-analyses, literature reviews, case reports, and original articles from the search engines and databases like PubMed, Scopus, ScienceDirect, Cochrane Library, Google Scholar, and BioMed Central, and studies with only human participants were included in this search. The knowledge sharing from this research may be utilised for enhancing the structured education diabetes programme and implementing the population-based corrective measures, including the thrust areas in future multi-centre longitudinal research studies and recommendations, which can prevent unnecessary complications and enhance their quality of life. Correct insulin administration technique, abstaining from administration of injection at the areas with lipohypertrophy, rotation of injection sites, and ultrasound scanning can be used as a complimentary method to detect the lipohypertrophy at an early stage. Liposuction is beneficial in reducing the extensive lipohypertrophic tissues but helps achieve only cosmetically satisfactory outcome; thus, empowering people to follow insulin injection technique guidelines is one of the best strategies to reduce the high prevalence of lipohypertrophy. To conclude, education among the people with DM, especially T1DM who have to take insulin regularly, needs to be carried out consistently in the clinical settings, to prevent the severe complications caused due to inappropriate insulin injection techniques.

Diabetes & metabolic syndrome. 2024;(2):102944
Abstract
BACKGROUND AND AIM South Asian migrants have a higher prevalence of chronic diseases than Caucasians. Despite much literature that has explored challenges in chronic disease management amongst the South Asian population in the past decades, their chronic disease management is still suboptimal. Understanding their determinants of disease management behaviour using the Theoretical Domains Framework will inform the development of a culturally sensitive intervention relevant to consumer-end-users. This study aimed to synthesise qualitative and quantitative studies on chronic disease management among adult South Asian immigrants. METHODS A mixed-methods systematic review was conducted using electronic databases. The Mixed Methods Appraisal Tool assessed the quality of the included studies. Quantitative data were transformed into qualitative data and analysed thematically. Subthemes were mapped in the Theoretical Domains Framework presenting barriers and facilitators under each theme. RESULTS 18293 studies were identified, of which 37 studies were included. The barriers and facilitators identified were categorised into four overarching themes: patient-provider interaction and relationship (e.g., complex language use by health professionals), the impact of migration (e.g., weather conditions had an impact on engagement with physical activity), heritage-based practices (e.g., an obligation to consume energy-dense food in social gatherings), and chronic disease management strategies (e.g., lack understanding of appropriate disease management strategies). CONCLUSION This review provides a comprehensive understanding of the complexity of chronic disease management among South Asian migrants and insights into developing multifaceted interventions to address barriers to chronic disease management, guiding the healthcare professionals in helping overcome South Asians perceived barriers to managing chronic disease in the host countries.

Metabolic Syndrome Among Adolescents Aged 10-19 Years in India: A Systematic Review and Meta-Analysis.
Varhlunchungi, V, Kalaivani, M, Hemraj, C, Gupta, S, Malhotra, S, Tandon, N
Cureus. 2023;(11):e48636
Abstract
Metabolic syndrome (MetS) is a group of metabolic abnormalities that include disturbed glucose metabolism, dyslipidemia, abdominal obesity, and arterial hypertension. Nutritional and lifestyle modifications have increased the risk of cardiometabolic disorders among adolescents. Studies conducted in various parts of India have shown a wide range of prevalence among adolescents aged 10-19 years. The various criteria for defining MetS have led to controversial diagnoses, providing inconsistent findings. Additionally, there is a paucity of national-level estimates on the prevalence of MetS in India. Therefore, this systematic review and meta-analysis were conducted to estimate the prevalence of MetS among adolescents. A comprehensive search was conducted to identify studies that reported the prevalence of MetS among adolescents in India. The search was performed using several databases, including PubMed, Embase, ScienceDirect, Scopus, Medline, Web of Science, Google, and Google Scholar. Relevant data were extracted and assessed for quality using the Critical Appraisal Skills Programme (CASP) guidelines. To estimate the pooled prevalence and explore heterogeneity, a random effects model and I2 statistic were used. Subgroup analyses were conducted based on criteria for defining MetS, sex, study setting, and study site. Sensitivity analysis was performed, and publication bias was also explored. A sample size of 19044 adolescents from 16 studies was included in the meta-analysis. The pooled prevalence of Mets among adolescents using the International Diabetes Federation (IDF) criteria was 3.4% (95% CI: 1.1-6.6%, I2=97.1%) and the National Cholesterol Education Program - Adult Treatment Panel III (NCEP-ATP III) criteria were 5.0% (95% CI: 3.3-6.9%, I2=95.9). The subgroup analyses did not reveal the reasons for heterogeneity, but sensitivity analysis showed a substantial change in the pooled estimate. Our study findings show that the prevalence of MetS among Indian adolescents is higher compared to other countries posing a challenge to address the necessity of intervention among adolescents. Standardizing the definition of MetS is necessary to avoid inconsistency in the estimates. The study findings highlight the need to strengthen existing adolescent programs through the encouragement of increased physical activity and the adoption of nutritious well-balanced diets to mitigate the burden of MetS among adolescents in India.

Abstract
BACKGROUND Dysphagia palliation in inoperable esophageal cancer continues to be a challenge. Self-expandable metal stents have been the mainstay of endoscopic palliation but have a significant risk of adverse events (AEs). Liquid nitrogen spray cryotherapy is an established modality that can be used with systemic therapy. This study reports the outcomes of cryotherapy, including dysphagia and quality of life (QoL), in patients receiving systemic therapy. METHODS This was a prospective multicenter cohort study of adults with inoperable esophageal cancer who underwent cryotherapy. QoL and dysphagia scores before and after cryotherapy were compared. RESULTS 55 patients received 175 cryotherapy procedures. After a mean of 3.2 cryotherapy sessions, mean QoL improved from 34.9 at baseline to 29.0 at last follow-up (P < 0.001) and mean dysphagia improved from 1.9 to 1.3 (P = 0.004). Patients receiving more intensive cryotherapy (≥ 2 treatments within 3 weeks) showed a significantly greater improvement in dysphagia compared with those not receiving intensive therapy (1.2 vs. 0.2 points; P = 0.003). Overall, 13 patients (23.6 %) received another intervention (1 botulinum toxin injection, 2 stent, 3 radiation, 7 dilation) for dysphagia palliation. Within the 30-day post-procedure period, there were three non-cryotherapy-related grade ≥ 3 AEs (all deaths). The median overall survival was 16.4 months. CONCLUSION In patients with inoperable esophageal cancer receiving concurrent systemic therapy, adding liquid nitrogen spray cryotherapy was safe and associated with improvement in dysphagia and QoL without causing reflux. More intensive treatment showed a greater improvement in dysphagia and should be considered as the preferred approach.
