Killer immunoglobulin like receptor gene profiling in Western Indian population

One hundred and sixty one healthy unrelated hematopoietic stem cell transplant donors from Western Indian were enrolled in this study. The study was initiated to observe the genotypic diversity of 16 killer immunoglobulin like receptor (KIR) genes in this population. KIR genotyping was carried out using the PCR-SSP technique. 56 KIR genotypes were observed in our population, where 15 genotypes were reported for the first time in any population. The KIR genotype data for the population can be accessed from Allele Frequencies Net Database under the population name “India Western KIR” and identifier “3570”.     

Evaluation of periodontal disease in dental students

A cross-sectional study was conducted on dental students at Bahadurgarh, Haryana, for the assessment of periodontal health and possible associated factors. A total of 329 students were examined clinically by periodontists. Students with bleeding on probing and attachment loss ≥ 2 mm were assessed further for extent of bone loss radiographically. The awareness of disease and knowledge of management was also assessed. Sixty-three (19.1%) students showed clinical signs of disease and 21 (6.3%) had cemento-enamel junction (CEJ) to the bone crest distance of ≥2 mm. Proximal carious lesions were observed in nine cases of attachment loss. Mottled enamel with a roughened surface had association with attachment loss. The clinical students showed reasonable knowledge of disease and management. The need to strengthen the diagnostics for early detection of periodontal disease in young adults is suggested.     

Impact of single immunosuppressive drug withdrawal on lymphocyte immunoreactivity

Background

Chronic rejection is a major cause of graft loss in kidney transplant recipients. Nonadherence to drug therapy is a well-recognized cause of chronic rejection leading to long-term graft dysfunction and failure for transplant recipients. Immunosuppressive medications with short half-lives that require frequent dosing, such as tacrolimus, complicate transplant regimens and may increase noncompliance. Regimens could be simplified using drugs with long half-lives requiring once-daily administration, such as sirolimus. The impact of missing doses of single agents has not been studied extensively. Erratic compliance or temporary discontinuation of immunosuppressive drugs may have significant implications for chronic rejection.

Methods

Our study evaluated the impact of single drug withdrawal of commonly used immunosuppressive agents (sirolimus and tacrolimus) on lymphocyte responses. We analyzed lymphocyte proliferation, cytokine secretion, and adenosine triphosphate generation using a crossover study design with normal healthy patients. Lymphocyte proliferation was assessed using 5-bromo-2-deoxyuridine incorporation, and T cell function was analyzed by examining adenosine triphosphate generation.

Results

Our results indicate that sirolimus exerts prolonged suppression of lymphocyte proliferation and decreased interleukin 17A that lasts up to 48 h after drug withdrawal. In comparison, tacrolimus did not have a similar effect on lymphocyte proliferation or interleukin 17A secretion.

Conclusion

Future analysis of sirolimus in diverse transplantation populations merits investigation.     

Electro-Mechanical Finger Prosthesis: A Novel Approach for Rehabilitation of Finger Amputees

Prosthesis refers to artificial replacement of an absent part of the human body. These prostheses help in psychological support of the patients and enhance their social acceptance. Complete or partial finger amputations are some of most frequently encountered forms of partial hand loss. Micro vascular reconstruction is the first choice of rehabilitation but when it is contraindicated, unavailable, unsuccessful or unaffordable, the prosthetic rehabilitation is an alternative for improving the psychological status of an individual. Most of these artificial prostheses make use of silicone. The present paper tries to combine aesthetics with function. The authors have created functionally active finger prosthesis with the help of electromechanical controls. The prosthesis is battery-powered, light-weight, and allows the user to regain complete control of flexion and extension movements of an artificial finger.

     

Current Allogeneic Hematopoietic Stem Cell Transplantation for Pediatric Acute Lymphocytic Leukemia: Success,Failure and Future Perspectives—A Single-Center Experience, 2008 to 2016

Hematopoietic stem cell transplantation (HSCT) is the only curative option for a subset of patients with high-risk or relapsed acute lymphoblastic leukemia (ALL). Given evolving practices, it is important to continually evaluate outcomes for pediatric ALL following HSCT. Outcomes after HSCT are influenced by the type of donor used as this determines the degree and method of T cell depletion used and, consequently, specific transplant-related morbidities. We retrospectively analyzed HSCT data from our center for transplants performed between January 2008 and May 2016, comparing outcomes among different donor types. One hundred and twenty-four pediatric patients underwent HSCT from a matched sibling donor (MSD; n?=?48), an unrelated matched donor (UMD; n?=?56), or a haploidentical donor (n?=?20). We observed a similar 3-year event-free survival (EFS) for MSD recipients (of .64) and for UMD recipients (.62), but a significantly lower EFS for recipients of haploidentical transplants (.35; P?=?.01). Relapse was the main cause of HSCT failure and was significantly higher in the haploidentical donor group (.47 versus .19 for MSD and .24 for UMD; P?=?.02). Treatment-related mortality was evenly distributed among the donor groups (.17, .16, and .15 for the MSD, UMD, and haploidentical groups, respectively). Rates of infection-related mortality were lower than previously reported. Relapse is the main obstacle for successful HSCT in the contemporary era, and this effect is most evident in recipients of haploidentical donor grafts. Newer methods to improve graft-versus-leukemia effect are being evaluated and will need to be incorporated into the management of high-risk patients.     

Physical activity as a clinical tool in the assessment of malnutrition

Objective

To measure physical activity in children with wasting and to look for association between poor physical activity and wasting.

Methods

Physical activity was measured in 56 children with wasting, using Children’s Activity Rating Scale, and compared with age- and sex-matched controls.

Results

A significant association was found between poor physical activity and malnutrition as determined by weight-for-height Z Score <-2 (P=0.001) and midupper-arm circumference (P=0.002).

Conclusion

Physical activity can be used as clinical parameter to assess malnutrition.     

Physical activity and quality of life in head and neck cancer survivors

Purpose To examine the prevalence of exercise in head and neck cancer survivors and determine preliminary associations with quality of life (QoL), fatigue, and depression.Materials and methods Fifty-nine of 65 (91%) eligible head and neck cancer survivors recruited from an academic oncology clinic completed a self-administered survey including the modified Godin Leisure-Time Exercise Questionnaire and Functional Assessment of Cancer Therapy-Head & Neck (FACT-H&N), which includes physical, social, emotional and functional well-being (FWB) as well as additional concerns, and the FACT-General (FACT-G). Medical variables were obtained by medical record review.Results The majority of participants were men (83%) and were Caucasian (92%), with mean age of 58±12.8. Cancer sites were primarily the oral cavity (24%), oropharynx (37%), or larynx (25%), with 20% being stage I, 7% stage II, 19% stage III, and 54% stage IV disease. Chemotherapy and/or radiation were ongoing in 14% of the participants. Half of the participants (51%) were diagnosed <6 months ago. Only three (5%) participants reported any vigorous exercise minutes (M=7.3±35.4), and only seven (12%) participants reported any moderate exercise minutes (M=19.5±70.6). Light exercise was reported by 26 (44%) (M=83.4±147.1). Only five (8.5%) participants were meeting current public health exercise guidelines. Partial correlations adjusting for age, medical comorbidity, and alcohol use showed that the total exercise minutes (i.e., light + moderate + vigorous) was positively associated with FWB (r=0.30, p=0.027), FACT-G (r=0.25, p=0.071), and FACT-H&N (r=0.26, p=0.064), was negatively associated with fatigue (r=−0.27, p=0.051), and had no association with depression (r=0.10, p=0.500).Conclusions Few head and neck cancer survivors are participating in any moderate or vigorous exercise, and over half are completely sedentary. Meaningful and potentially beneficial associations between total exercise minutes, QoL, and fatigue were demonstrated. An exercise intervention may have utility in this understudied cancer survivor group. Further research is warranted.     

Embracing technology in cataract surgical training – The way forward

While ophthalmology as a surgical branch itself has evolved technologically with newer instruments, techniques and procedures; ophthalmic surgical training appears to have stagnated in terms of how it is delivered and how trainees’ learning and performance are assessed. This collaborative editorial attempts to identify the lacunae in ophthalmic residency training and highlight how technological tools such as surgical simulators can be incorporated into ophthalmic training even in limited-resource settings with good results.
