The Impact of a Brief Intervention on Medical Students\u27 Readiness to Screen for DV - Changes in Decisional Balance and Self-Efficacy
Introduction: Domestic violence (DV) affects millions of Americans each year. Yet, there is a dearth of theory-based DV curricula, resulting in physicians unprepared to screen for DV. This study utilized a survey based on constructs from the Transtheoretical Model to assess the readiness of first- and second-year medical students to screen for DV. Information from this survey will be used to help institutionalize DV education into the medical curriculum. [See PDF for complete abstract
Effect of diuretics on sodium, potassium and chloride levels- a cross sectional study
Background: Diuretics are one of the widely used class of drugs used in various cardiovascular and other disorders. However, they can cause various metabolic adverse effects, electrolyte imbalance being among important changes.Methods: A cross sectional study was conducted in which patients diagnosed with hypertension for at least one month were included. Over a period of 6 months patients were enrolled irrespective of whether they were taking diuretics or not. Demographic details, drug therapy and electrolyte levels were recorded in a proforma. Data was analyzed for difference in serum electrolyte levels between diuretic and nondiuretic groups as well as between different diuretic groups.Results: Out of total 177 participants, 71 were on diuretic therapy. There was significant difference in mean serum sodium (S. Na), potassium (S. K) and chlorine (S. Cl) levels between diuretic and nondiuretic groups (P<0.05). Hyponatremia, hypokalemia and hyperkalemia were observed. Thiazide diuretic group showed significantly greater hyponatremia compared to other diuretics (P=0.028). Hyperkalemia was observed in participants receiving K sparing diuretic or combination of loop and K sparing diuretics. Old age and number of comorbidities showed negative association with S. Na. Females had significantly more hyponatremia than male participants.Conclusions: The study confirms that diuretics cause various abnormalities in electrolytes namely Na and K levels. Old age, comorbidities and female sex are risk factors for hyponatremia

Role of doppler in fetal growth restriction
Background: Fetal growth restriction is an important and particularly challenging problem for modern obstetricians and paediatricians. The present study is to correlate the importance of Doppler velocimetry and perinatal outcome in cases of growth restricted foetuses by comparing perinatal outcome of control & study groups with normal and abnormal Doppler waveforms.Methods: A study and a control group comprising of 50 pregnant women having growth restricted foetuses in each group was matched for all other confounding factors except for Doppler changes. These patients were followed up and the perinatal outcomes of FGR foetuses having Doppler changes was compared with those having normal Doppler studies.Results: In our study, alteration in both MCA and UmbA Doppler was associated with perinatal morbidity and NICU admissions in 64% and mortality in 28%. Doppler changes showing altered CPR less than 1 had adverse outcome with NICU admission in 61% and mortality in 34%. Alteration in DV Doppler was associated with perinatal morbidity and NICU admissions in 17% cases and mortality in 83% cases, with no pregnancies having a healthy outcome. Among high-risk pregnancies with suspected IUGR, the use of Doppler assessment significantly decreases the likelihood of labor induction, caesarean delivery, and perinatal deaths.Conclusions: Abnormal Doppler waveform changes indicate adverse perinatal outcome of pregnancies with FGR. Doppler study helps to reduce perinatal mortality and morbidity by timely and appropriate interventions
Study of Thermal Properties on UV-Curable Coatings Derived from Oleochemical Polyols
Abstract: Over the last few years, UV radiation curing has become a well established coating technology used for several different applications. Polymeric component based on renewable resource is another area for getting low VOC coatings. In the present study cellulose and soya fatty acid were used to prepare oleochemical polyols which in turn reacted with diisocyanates to get PU which is further reacted with hydroxyl terminated acrylates to get oligomeric urethane acrylates. These polymeric compounds are used without any organic solvent for UV-coating formulation and cured by UV light on the metal surfaces. Thus effect of different types of polyols were used to prepared UV coatings studied on thermal properties like dynamic mechanical properties (DMA) and thermogravimetric analysis (TGA

aRrayLasso: a network-based approach to microarray interconversion
Summary: Robust conversion between microarray platforms is needed to leverage the wide variety of microarray expression studies that have been conducted to date. Currently available conversion methods rely on manufacturer annotations, which are often incomplete, or on direct alignment of probes from different platforms, which often fail to yield acceptable genewise correlation. Here, we describe aRrayLasso, which uses the Lasso-penalized generalized linear model to model the relationships between individual probes in different probe sets. We have implemented aRrayLasso in a set of five open-source R functions that allow the user to acquire data from public sources such as Gene Expression Omnibus, train a set of Lasso models on that data and directly map one microarray platform to another. aRrayLasso significantly predicts expression levels with similar fidelity to technical replicates of the same RNA pool, demonstrating its utility in the integration of datasets from different platforms. Availability and implementation: All functions are available, along with descriptions, at https://github.com/adam-sam-brown/aRrayLasso.

Unusual presentation: fracture neck femur in 18 months old child
An 18 months old child was brought to the emergency department with alleged history of trauma due to hit by two wheeler and sustained injury over right hip. Child was not able to move the right lower limb. Physical examination of child revealed contusion over right hip region and injury over perineal region. There was no active vaginal bleeding. Rest of the systemic examination was normal. Routine blood was normal. On X-ray of pelvis with both hip showed fracture of neck femur on right side without any pelvic injury. Patient was treated with hip spica cast and complete bed rest for 1 month. After 1 month of the treatment, on follow-up the patient was able to weight bear and fractured was united on X-ray
Enkephalin Therapy Improves Relapsing-Remitting Multiple Sclerosis
Multiple sclerosis (MS) is accompanied by decreases in serum endogenous enkephalin/endorphins and alterations in inflammatory cytokines. This retrospective analysis of serum levels was conducted in 53 patients with established relapsing-remitting MS treated with the disease-modifying therapies (DMT) glatiramer acetate, dimethyl fumarate or with the biotherapeutic low dose naltrexone (LDN) to elevate enkephalins, an off-label alternative. Opioid growth factor (OGF), an inhibitory endogenous opioid involved in modulating cellular replication, was measured and correlated to serum β-endorphin, IL-17A and TNFα. Results revealed that MS leads to a significant reduction in OGF levels in subjects on DMTs, but patients on LDN had OGF levels comparable to non-MS controls. Individuals on DMTs had significantly elevated TNFα levels, while IL-17A levels were significantly elevated only in patients taking dimethyl fumarate. A direct correlation was established between OGF and IL17A indicating a potential interaction between the OGF-OGFr axis and pro-inflammatory T-helper cells providing insight into the disease etiology
