Review of the renal endpoints used in cardiovascular safety clinical trials in type 2 diabetes mellitus patients and their importance in primary care

Chronic kidney disease (CKD) is one of the most common complications of type 2 diabetes mellitus (T2DM). Furthermore, CKD confers a considerable increase in the risk of cardiovascular (CV) morbidity and mortality. In line with the need to improve knowledge in this field, this article aims to describe the renal endpoints used in the different cardiovascular outcome trials (CVOTs). The objective is to better know the renal variables used in the different CVOTs in order to optimize the implementation of advances in the prevention of progressive diabetic kidney disease in patients with T2DM in clinical practice.

A cross-national comparison of the Twitter feeds of popular alcohol brands in India and Australia

Aims: To evaluate (i) the types of techniques alcohol marketers utilise to facilitate user engagement with content on leading Indian and Australian Twitter alcohol brand pages and (ii) the extent to which users engage with this content in two diverse national contexts.

Methods: The 10 alcohol brands per country with the greatest Twitter presence were identified based on the number of ‘followers’. Number of tweets, photos, and videos were collected and the type of content noted for each brand between 1 January 2016 and 29 February 2016. The data were analysed via an inductive coding approach using NVivo10.

Results: In total, the brands had accumulated up to 150,386 followers (Indian: 110,032; Australian: 40,354). The techniques utilised were a mix of those that differed by country (e.g. India: sexually suggestive content versus Australia: posts related to the brand’s tradition or heritage) and generic approaches (e.g. alcohol sponsorship of sport, music, and fashion; offering consumption suggestions; organising competitions; giveaways; and use of memes).

Conclusions: The flexibility of Twitter, which complements traditional marketing, allows brands to adapt and deliver their online alcohol content in specific national contexts and to capitalise on the cultural meanings users invoke in their interactions with the brands.     

Causes of Missed Referrals to Low-Vision Rehabilitation Services: Causes in a Tertiary Eye Care Setting

Purpose: To identify the referral pattern and identify causes of missed referrals to low-vision services in a tertiary eye care center. Methods: A retrospective review of all the hospital records of patients seen from September-December 2012 was done to identify patients with visual impairment. Low vision was defined as has a best-corrected visual acuity (BCVA) in the better eye of <20/60 to light perception (as per WHO definition); or a visual field of <20° from the point of fixation. The frequency of referrals in this database was used to identify referral patterns of physicians and also causes for missed referrals for these patients. Results: Of 14,938 hospital medical records reviewed during the period, 499 patients missed low-vision services with a mean age of 46?±?18.2 years, including 158 females. Among those missed, 12.07% were in the age group 0-15 years, while 30.9% of the patients were >60 years, with 157 requiring rehabilitative services and training. Causes for missed referrals were clear misses or non-referrals by the physician (39%), non-acceptance of services by the patient (53%), loss from appointment desks (4.5%), and loss to follow-up (3.5%). Conclusion: Missed referral to low-vision services in tertiary centers can be considerable; these need to be identified for optimal utilization and delivery of these services to patients with low vision.     

Association of sleep problems and sleep duration with self-rated health and grip strength among older adults in India and China: results from the study on global aging and adult health (SAGE)

Background

Sleep is an important predictor of health and quality of life. This study examined the association between sleep problems and sleep duration with self-rated poor health and grip strength among respondents aged 50 years and above in India and China.Methods: The data for this study were derived from the first wave of WHO’s Study on Global Aging and Adult Health (SAGE), a nationally representative panel survey conducted in six LMICs. Grip strength and poor self-rated health were the main outcome variables, while sleep problems and sleep duration were the main predictors. Multivariate logistic regression models and ordinary least squares regression models were used to understand the association between sleep problems and sleep duration with poor self-rated health and grip strength.

Results

Sleep problems and sleep duration were strongly and significantly associated with poor self-rated health and grip strength in India and China. Compared to older adults with no sleep problems, the odds ratio for poor self-rated health among older adults with sleep problems was 4.86 (95% CI?=?4.12, 5.73, p?<?0.01) and 5.06 (95% CI?=?3.93, 6.51, p?<?0.01) higher for India and China, respectively. The likelihood of reporting poor health was higher among older adults who got ≤ 6 or 10+ h of sleep in both India and China. A negative and significant association was found between longer sleep duration and grip strength only in China (β?=??1.19, 95% CI?=??1.78, ?0.60, p?<?0.01).

Conclusion

We observed a significant association between sleep problems and sleep duration with poor self-rated health and grip strength. Results suggested that sleep problems are important factors in determining the health of older adults in low- and middle-income countries.

     

Coexisting lumbar and cervical stenosis (tandem spinal stenosis): an infrequent presentation. Retrospective analysis of single-stage surgery (53 cases)

Study design

Retrospective analysis of 53 patients who underwent single stage simultaneous surgery for tandem spinal stenosis (TSS) at single centre.

Objective

To discuss the presentation of combined cervical and lumbar (tandem) stenosis and to evaluate the safety and efficacy of single-stage simultaneous surgery.

Summary of background data

Combined stenosis is an infrequent presentation with mixed presentation of upper motor neuron and lower motor neuron signs. Scarce literature on its presentation and management is available. There is a controversy in the surgical strategy of these patients. Staged surgeries are frequently recommended and only few single-stage surgeries reported.

Methods

All the patients were clinico-radiologically diagnosed TSS. Surgeries were performed in single stage by two teams. Results were evaluated with Nurick grade, modified Japanese Orthopedic Association score (mJOA), oswestry disability index (ODI), patient satisfaction index, mJOA recovery rate, blood loss and complication.

Results

The mJOA cervical and ODI score improved from a mean 8.86 and 68.15 preoperatively to 13.00 and 30.11, respectively, at 12 months and to 14.52 and 24.03 at final follow-up. The average mJOA recovery rate was 48.23 ± 26.90 %. Patient satisfaction index was 2.13 ± 0.91 at final follow-up. Estimated blood loss of ≤400 ml and operating room time of <150 min showed improvement of scores and lessened the complications. In the age group below 60 years, the improvement was statistically significant in ODI (p = 0.02) and Nurick’s grade (p = 0.03) with average improvement in mJOA score.

Conclusion

Short-lasting surgery, single anaesthesia, reduced morbidity and hospital stay as well as costs, an early return to function, high patient satisfaction rate with encouraging results justify single-stage surgery in TSS. Age, blood loss and duration of surgery decide the complication rate and outcome of surgery. Staged surgery is recommended in patients above the age of 60 years.     

Increasing access to renal transplantation in India through our single‐center kidney paired donation program: a model for the developing world to prevent commercial transplantation

Because access to transplantation with HLA‐desensitization protocols and ABO incompatible transplantation is very limited due to high costs and increased risk of infections from more intense immunosuppression, kidney paired donation (KPD) promises hope to a growing number of end‐stage renal disease (ESRD) patient in India. We present a government and institutional ethical review board approved study of 56 ESRD patients [25 two‐way and 2 three‐way pairs] who consented to participate in KPD transplantation at our center in 2013, performed to avoid blood group incompatibility (n = 52) or positive cross‐match (n = 4). All patients had anatomic, functional, and immunologically comparable donors. The waiting time in KPD was short as compared to deceased donor transplantation. Laparoscopic donor nephrectomy was performed in 54 donors. Donor relationships were spousal (n = 40), parental (n = 13), others (n = 3), with median HLA match of 1. Graft survival was 97.5%. Three patients died with functioning graft. 16% had biopsy‐proven acute rejection. Mean serum creatinine was 1.2 mg/dl at 0.73 ± 0.32 months follow‐up. KPD is a viable, legal, and rapidly growing modality for facilitating LDRT for patients who are incompatible with their healthy, willing living donor. To our knowledge, this is the largest single‐center report from India.     

The role of laparoscopy in children with groin problems

The use of laparoscopic surgery has grown dramatically in recent years in most all types of surgery. Historically, the early use of laparoscopic surgery was for pelvic and groin problems. In this article we review the current technique, indications, benefits and complications of laparoscopy in diagnosis and management of various groin problems in children including undescended testes (non-palpable and palpable) and inguinal hernia.     

Lumbar microdiscectomy as a day-case procedure: Scope for improvement?

Background and purpose

There are no significant differences in outcomes between patients receiving inpatient and day-case lumbar microdiscectomy, but the latter is still underused in the NHS. Here we aimed to identify factors contributing to successful same-day discharge in day-case patients.
