Pearl Millet Mapping Population Parents: Performance and Selection Under Salt Stress Across Environments Varying in Evaporative Demand

It is vital to screen the germplasm of crop plants for salt stress tolerance so as to utilize them in breeding programs. Accordingly, in the present study, twenty diverse inbred lines, parents of mapping populations of pearl millet were chosen to determine the phenotypic contrasts for seed yield, which can open the way for developing salt tolerance QTLs. Parents were grown in two summer seasons (late and early) with VPD ≥ 2 kPa, and one rainy season with VPD < 2 kPa, during flowering and grain filling under saline (150 and 200 mM) and non-saline (0 mM) conditions. Salinity delayed flowering time by a fortnight in the summer seasons but only 5–6 days in the low VPD rainy season. Salinity decreased grain yield by 86% in late-summer and 80% in early-summer, but less than 70% in rainy season. GY penalty was higher than vegetative biomass under saline conditions especially in summer season when the evaporative demand was very high. It appears that reproduction and grain filling are sensitive to high temperature that can compound the effect of salinity and high VPD. GY of inbreds under salinity was not better in comparison with non-saline conditions. DOF and grain density (thousand grain weight) were found as important correlated traits under salinity. Also, GY was affected significantly if VPD increased during flowering time.

The value of prognostic indices for pneumonia

One of the most important decisions in the management of community-acquired pneumonia is deciding the care site, which affects morbidity, mortality, and costs. Clinical judgment alone is difficult and imprecise. The Pneumonia Severity Index score and the CURB-65 (confusion, urea nitrogen, respiratory rate, blood pressure, 65 years of age and older) score are validated prognostic indices to predict mortality, and they can identify low-risk patients who may be eligible for outpatient management. However, limitations of the scoring systems preclude their isolated use, and they can only be recommended as an aid to guide hospital admission decisions. The Pneumonia Severity Index score is slightly better at identifying the lowest risk patients, whereas CURB-65 is much simpler to use. As an adjunct to clinical judgment, we consider CURB-65 to be the most useful prognostic index for identifying low-risk patients.     

UK National Audit of chlamydial infection management in sexual health clinics. clinic policies audit

There was a wide range of activity and chlamydial diagnoses between the 177 clinics that responded. Most (92%) clinics have nucleic acid tests for chlamydial diagnosis. Different practitioners largely share roles in providing advice to patients about partner notification, treatment adherence, safer sex advice and abstinence. Most (97%) clinics have information leaflets about chlamydia, although about 30% of clinics lack leaflets containing information about antibiotics and hormonal contraception. About two-third clinics follow the National Guideline recommended interval for providing a test of cure where this is indicated. Only 18% of clinics routinely ask patients to reattend, with 40% having a policy of no routine follow-up and 62% using telephone or text follow-up. These categories were not mutually exclusive. Most (86%) of the 146 English clinics had a local Chlamydia Screening Programme coordinator for their Primary Care Trust area, although cooperation varies, with cooperation over treatment of 70% and Programme policy of 62%.     

Quality standards for bone conduction implants

Conclusion: Bone conduction implants are useful in patients with conductive and mixed hearing loss for whom conventional surgery or hearing aids are no longer an option. They may also be used in patients affected by single-sided deafness. Objectives: To establish a consensus on the quality standards required for centers willing to create a bone conduction implant program. Method: To ensure a consistently high level of service and to provide patients with the best possible solution the members of the HEARRING network have established a set of quality standards for bone conduction implants. These standards constitute a realistic minimum attainable by all implant clinics and should be employed alongside current best practice guidelines. Results: Fifteen items are thoroughly analyzed. They include team structure, accommodation and clinical facilities, selection criteria, evaluation process, complete preoperative and surgical information, postoperative fitting and assessment, follow-up, device failure, clinical management, transfer of care and patient complaints.     

Anti-IL-17 therapy in treatment of rheumatoid arthritis: a systematic literature review and meta-analysis of randomized controlled trials

IL-17 has a role in inflammation in RA, and its levels in joints correlate with disease severity. Multiple RCTs have been performed to study effects of anti-IL-17 agents. The objective of this study was to perform a systematic review and meta-analysis to analyze the efficacy and safety of anti-IL-17 agents in the management of RA. This work is based on a systematic review of studies retrieved by a sensitive search strategy in PubMed, EMBASE and Cochrane CENTRAL from inception through 9/7/15. Study selection criteria were the following: adult patients (age ≥ 18 years) with RAs, random selection of patients for anti-IL-17 therapy and treatment response compared to placebo. We performed systematic literature review per PRISMA guideline and two investigators independently selected seven randomized clinical trials (RCTs) for meta-analysis. We used random effect model calculating odds ratio (OR) and 95 % confidence interval (CI) to measure the efficacy with ACR20/50/70 responses and the safety with adverse events. Seven studies with total of 1226 patients including 905 in anti-IL-17 group and 321 in placebo were included in the meta-analysis. Anti-IL-17 was effective in achieving ACR20 and ACR50 compared to placebo (OR 2.47, 95 % CI 1.29–4.72, P = 0.006, I ² 77 % and OR 2.94, 95 % CI 1.37–6.28, P = 0.005, I ² 64 %, respectively). Data analysis for ACR70 showed a favorable trend toward anti-IL-17 (OR 2.62, 95 % CI 1–6.89, P = 0.05, I ² 15 %). Subgroup analysis of ACR20 for individual anti-IL-17 agents showed that ixekizumab was more effective than placebo, while secukinumab showed a trend toward achieving the ACR20 response. However, brodalumab was not effective compared to placebo. Safety analysis did not show increased risk of any or serious adverse effects by anti-IL-17 compared to placebo (OR 1.23, 95 % CI 0.94–1.61, P = 0.13, I ² = 0 % and OR 1.28, 95 % CI 0.57–2.88, P = 0.55, I ² = 0 %, respectively). This meta-analysis concludes that anti-IL-17 is effective in the treatment of RA without increased risk of any or serious adverse effects; however, the results are limited by significant heterogeneity and small duration of studies.     

Positive Airway Pressure Adherence in Patients with Obstructive Sleep Apnea with Schizophrenia

Introduction

To determine the 1-year and 3-year adherence rates with Positive Airway Pressure (PAP) therapy in patients with schizophrenia compared to matched controls.

Methods

A case–control retrospective analysis was performed in a Veterans Affairs hospital. All symptomatic patients with schizophrenia ever started on PAP therapy between 2007 and 2015 were compared with controls matched for severity of sleep apnea based on AHI, BMI, and age at the time of diagnosis.

Results

Total number of subjects in both groups was 39. Mean AHI among cases and controls was 27.63 ± 22.16 and 33.59 ± 44.04 (p = 0.32), mean BMI was 34.91 ± 5.87 and 33.92 ± 5.21 (p = 0.43), and mean age at diagnosis was 53.6 ± 11.75 and 55.97 ± 11.92 (p = 0.36), respectively. There was no statistically significant difference in PAP use between patients with schizophrenia and controls at 1-year (percent days device use > 4 h—36.43% ± 31.41 vs. 49.09% ± 38.76; p = 0.17) and 3-year (percent days device use > 4 h—42.43 ± 35.50 vs. 60.53 ± 38.56; p = 0.089) visits

Conclusions

PAP adherence and usage is not significantly different among patients with schizophrenia compared to matched controls. Therefore, schizophrenia does not appear to influence CPAP compliance.

     

Microsurgical outcome in posttraumatic brachial plexus injuries in children

Purpose

The purpose of the study was to analyze the surgical outcomes in children (≤18 years) with brachial plexus injury operated between April 2008 and March 2012 at our center.

Methods

All children <18 years of age admitted to our center and surgically treated with a diagnosis of posttraumatic brachial plexus injury were included in the study. The demographic details of these patients were retrieved from the computerized database of our hospital. The results were analyzed in terms of the mode of injury, type of injury, surgical procedure performed, and motor recovery after the surgery (MRC Grading). Motor recovery with MRC >3/5 was termed as good outcome.

Observations

A total of 33 patients were surgically treated. The mean age at presentation was 15.1 (range 4–18) years. Boys constituted 79 % (n?=?26) of our patient population. High-velocity injury was the commonest mode of injury. Panbrachial injury was the commonest seen in 82 % (n?=?27) of patients. Mean duration between injury and surgical intervention was 6 (range 2–13, SD?±?2.6) months. Majority of patients underwent neurotization procedure. Mean follow-up was 32 (range 6–51) months.

Conclusions

High-velocity trauma is the most common mode on injury. Global palsy involving all the plexal elements was present in 82 % of the children. Neurotization was the most commonly performed surgical procedure. Good motor outcome (MRC grade ≥3/5) was seen in 62 % of patients.     

Major Osteoporotic to Hip Fracture Ratios in Canadian Men and Women With Swedish Comparisons: A Population‐Based Analysis

Fracture Risk Assessment (FRAX) tools are calibrated from country‐specific fracture epidemiology. Although hip fracture data are usually available, data on non‐hip fractures for most countries are often lacking. In such cases, rates are often estimated by assuming similar non‐hip to hip fracture ratios from historical (1987 to 1996) Swedish data. Evidence that countries share similar fracture ratios is limited. Using data from Manitoba, Canada (2000 to 2007, population 1.2 million), we identified 21,850 incident major osteoporotic fractures (MOF) in men and women aged >50 years. Population‐based age‐ and sex‐specific ratios of clinical vertebral, forearm, and humerus fractures to hip fractures were calculated, along with odds ratios (ORs) and 95% confidence intervals (CIs). All ratios showed decreasing trends with increasing age for both men and women. Men and women showed similar vertebral/hip fracture ratios (all p > 0.1, with ORs 0.86 to 1.25). Forearm/hip and humerus/hip fracture ratios were significantly lower among men than women (forearm/hip ratio: p < 0.01 for all age groups, with ORs 0.29 to 0.53; humerus/hip ratio: p < 0.05 for all age groups [except 80 to 84 years] with ORs 0.46 to 0.86). Ratios for any MOF/hip fracture were also significantly lower among men than women in all but two subgroups (p < 0.05 for all age groups [except 80 to 84 and 90+ years] with ORs 0.48 to 0.87). Swedish vertebral/hip fracture ratios were similar to the Canadian fracture ratios (within 7%) but significantly lower for other sites (men and women: 46% and 35% lower for forearm/hip ratios, 19% and 15% lower for humerus/hip ratios, and 19% and 23% lower for any MOF/hip ratios). These differences have implications for updating and calibrating FRAX tools, fracture risk estimation, and intervention rates. Moreover, wherever possible, it is important that countries try to collect accurate non‐hip fracture data. © 2014 American Society for Bone and Mineral Research
