Status of epilepsy in the tropics: An overlooked perspective.

Epilepsy is one of the most common serious chronic neurological diseases affecting people of all ages globally. It is characterized by recurrent seizures. About 50 million people worldwide have epilepsy. Indubitably, people with epilepsy (PWE) may be without access to appropriate treatment. Many studies have examined the molecular mechanisms and clinical aspects of epilepsy; nonetheless, the treatment gap exists in some special areas. In the tropics, the specific geographical and ecological conditions and a lack of medical resources result in neglect or delay of diagnosis for PWE. Herein, we summarized the epidemiology of epilepsy in the tropics and discussed the disease burden and existing problems, aiming to offer a medical environment for patients in need and highlight the importance of reducing the epileptic disease burden in tropical countries.

The use of Broca index to assess cut- off points for overweight in adults: A short review.

The Broca formula was developed in 1871 by Pierre Paul Broca (a French Army Doctor) to help establish ideal body weight or normal body weight. Initially, the Broca Index (BI) was used to work out the normal weight but was later expanded to ideal Body Weight. Ideal Body weight (kg) = [Height (cm)-100]. The common methods used to explore the levels of adiposity include body mass index (BMI), waist circumference, skinfolds, bioelectrical impedance analysis, dual energy x-ray absorptiometry (DEXA), computerized tomography (CT) and magnetic resonance imaging (MRI). Even though there have been several anthropometric measurements discoveries to assess obesity, BMI is still widely used in many clinic centers around the world. It remains simple and relatively inexpensive to measure and easily obtainable in non-laboratory settings. In this review, we will summarize the common methods used to measure body fat and their limitations. Second, we will show the correlation that may exist between Broca Index and BMI cutoffs. Last, we will underline some potential clinical usefulness that may present Broca index in assessing body fat.

The association between insurance coverage for insulin pen needles and healthcare resource utilization among insulin-dependent patients with diabetes in China.

BACKGROUND: Pen needles are an important component of insulin delivery among patients with diabetes, but are not universally covered in China. We compared clinical and economic characteristics of insulin-dependent patients in China who have some level of pen needle (PN) reimbursement to those with no PN reimbursement. METHODS: A cross-sectional study was conducted among 400 insulin users with Type 1 or Type 2 diabetes treated in outpatient endocrinology units of four large tertiary care hospitals in Nanjing, Chongqing, Beijing and Zhengzhou. Demographics, medical history, healthcare resource utilization (RU), out-of-pocket costs, insurance and PN reimbursement status were surveyed. Unit costs were assigned to healthcare RU and compared using descriptive statistics and multivariate regression models. RESULTS: A total of 400 patients were analyzed; 142 (35.5%) with some level of PN coverage/reimbursement and 258 (64.5%) without. Patients without PN reimbursement had a higher prevalence of lipohypertrophy (59.3% vs. 40.7%, p = 0.0007), greater median PN reuse (12 vs. 7 times per needle, p < 0.0001), greater 6-month insulin costs (1591 vs. 1328 Renminbi [RMB], p = 0.0025) and total unadjusted 6-month expenditures (6433 vs. 4432 RMB, p < 0.0001), respectively. After controlling for clinical and demographic characteristics, patients without PN reimbursement had 4.6 times greater odds of high costs compared to those with PN reimbursement. CONCLUSIONS: Insulin users without PN reimbursement may pose a greater economic burden to China compared to those with PN reimbursement. Expansion of insurance coverage for insulin PNs can improve the quality of care and potentially help reduce the economic burden in this population.

Lipohypertrophy in China: Prevalence, Risk Factors, Insulin Consumption, and Clinical Impact.

BACKGROUND: Lipohypertrophy (LH) is a complication of insulin therapy. We assessed LH prevalence, risk factors, insulin usage, and clinical and health economic effects in China. METHODS: In four cities, 401 adult patients injecting insulin ≥1 year were surveyed for diabetes/insulin injection history and practices, pen needle reimbursement (PNR), and health resource utilization, followed by structured examination and HbA1c testing. Differences between those with and without LH were evaluated by Student's t-test or the Wilcoxon rank sum test. Insulin costs were calculated. RESULTS: Patients were 59.6 ± 11.5 years old; 50% male; 93.5% type 2 diabetes. LH prevalence was 53.1%. Compared to those without LH, patients with LH had higher body mass index (BMI; 26 vs. 24.8 kg/m2) and HbA1c (8.2% vs. 7.7% [66 vs. 61 mmol/mol]), took 11 IU (0.13 IU/kg or 31.7%) more insulin costing $1.4 versus $1.0 (RMB 9.5 vs. 6.8) daily, reused PNs more times, and had less PNR (all P ≤ 0.003). LH patients correctly rotated injection sites less often (67.6% vs. 92.3%, P < 0.0001). By stepwise logistic regression, BMI, needle reuse frequency, and PNR remained modestly associated with LH prevalence (odds ratios [OR] <1.9; P ≤ 0.03); weight-adjusted insulin dose and incorrect site rotation showed ORs of nearly 7 and 8.4, respectively (P ≤ 0.001). Extrapolated to 9 million insulin-injecting patients in China and adjusted for therapy adherence, LH-related excess annual insulin consumption cost is estimated at nearly $297 million (RMB 2 billion). CONCLUSIONS: LH is common in China and associated with worse glycemic control, despite nearly one-third greater insulin consumption, with large cost implications. Proper injection technique education may reduce LH prevalence.
