Study of management of diaphyseal fracture shaft femur by intramedullary interlocking nail
Background: Aim of this study was to analyze the effectiveness of interlocking nail in management of femoral diaphyseal fractures with special reference to fracture anatomy, pattern and status of stability.Methods: This hospital based prospective study was done in the department of Orthopedics, MGM Medical College Navi Mumbai. A total of 41 patients who were admitted in our institute was included to evaluate management of diaphyseal fracture shaft femur by intramedullary interlocking nail from July 2015 to July 2017. They were asked to follow up at 6 weeks, 3 months and 6 months.Results: Most of the fractures (70.7%) were united in 16-20 weeks while 10 (24.4%) fractures were united in 10-15 weeks and 2 (4.9%) fractures were united in 21-25 weeks. The mean time to union was 16.87±3.09 weeks. In the present study, 26 out of 41 patients had excellent results (63.4%) with full, pain free, function of the extremity. 13 patients with good result (31.8%), 9 patients had flexion deformity 1200, 3 patients had shortening 2 cm, 2 patients had shortening 1 cm. Two patients with fair result (4.8%), both had flexion deformity and none had with poor result. So overall, we had 95.2% excellent to good and 4.8% fair results.Conclusions: Interlocking intramedullary nailing is the most effective ad successful method of definitive primary treatment, in most types of fractures of femur shaft. It provides strong fixation, rotational stability and earliest return to functional status, as rate of healing is good with nailing
ASHA Workers and Adolescent Health: An Explorative Study
Introduction: Adolescents constitute around 1.2 billion population of the world. Despite the fact that adolescents represent almost one quarter of the Indian population, their health needs are poorly understood and ill served. ASHAs being front line workers may play a significant role in addressing adolescence health issues at community level.Objective: To assess awareness and practices of ASHA workers regarding adolescent health issues.Materials and Methods: A cross-sectional study conducted among 1650 ASHA workers in Sonepat District of Haryana who had gathered for a training session on adolescent health. Before the session, a questionnaire in local language was distributed to assess their understanding about adolescent health issues. Data was analyzed using SPSS software (version 17). Results were presented in simple proportions and means (+SD).Results: Mean age (+SD) of ASHAs was 38.74 + 8.7 years. Maximum 1178 (71.4%) belonged to age group of 25-45 years. 1582 (95.9%) ASHAs were aware that adolescence age group was constituted by 10-19 years. 435 (26.4%) knew of anemia, 368 (22.3%) knew of vaginal discharge, 292 (17.7%) knew of menstrual problems as common problem in adolescence age group. 1297 (78.6%) reported condoms, 58 (3.5%) tubectomy, 139 (8.4%) oral pills as contraceptive methods for adolescence.Conclusion: ASHA workers should be trained adequately about adolescence health issues so that continuum of care under RMNCHA plus can be achieved. Training should provide complete knowledge about the same
Multiple urinary bladder masses from metastatic prostate adenocarcinoma
We present an unusual case of metastatic prostate adenocarcinoma that manifested with multiple exophytic intravesical masses, mimicking a multifocal primary bladder tumor. Biopsy with immunohistochemical analysis confirmed metastatic prostate adenocarcinoma. The patient was treated palliatively with external beam radiotherapy to prevent possible symptoms from local tumor progression. This case illustrates that when a patient with known prostate cancer presents with multifocal bladder tumors, the possibility of metastatic prostate cancer should be considered
Antiangiogenic Effects and Therapeutic Targets of Azadirachta indica Leaf Extract in Endothelial Cells
Azadirachta indica (common name: neem) leaves have been found to possess immunomodulatory, anti-inflammatory and anti-carcinogenic properties. The present study evaluates anti-angiogenic potential of ethanol extract of neem leaves (EENL) in human umbilical vein endothelial cells (HUVECs). Treatment of HUVECs with EENL inhibited VEGF induced angiogenic response in vitro and in vivo. The in vitro proliferation, invasion and migration of HUVECs were suppressed with EENL. Nuclear fragmentation and abnormally small mitochondria with dilated cristae were observed in EENL treated HUVECs by transmission electron microscopy. Genome-wide mRNA expression profiling after treatment with EENL revealed differentially regulated genes. Expression changes of the genes were validated by quantitative real-time polymerase chain reaction. Additionally, increase in the expression of HMOX1, ATF3 and EGR1 proteins were determined by immunoblotting. Analysis of the compounds in the EENL by mass spectrometry suggests the presence of nimbolide, 2′,3′-dehydrosalannol, 6-desacetyl nimbinene and nimolinone. We further confirmed antiproliferative activity of nimbolide and 2′,3′-dehydrosalannol in HUVECs. Our results suggest that EENL by regulating the genes involved in cellular development and cell death functions could control cell proliferation, attenuate the stimulatory effects of VEGF and exert antiangiogenic effects. EENL treatment could have a potential therapeutic role during cancer progression
Physiological and Proteomic Analysis of the Rice Mutant cpm2 Suggests a Negative Regulatory Role of Jasmonic Acid in Drought Tolerance
It is widely known that numerous adaptive responses of drought-stressed plants are stimulated by chemical messengers known as phytohormones. Jasmonic acid (JA) is one such phytohormone. But there are very few reports revealing its direct implication in drought related responses or its cross-talk with other phytohormones. In this study, we compared the morpho-physiological traits and the root proteome of a wild type (WT) rice plant with its JA biosynthesis mutant coleoptile photomorphogenesis 2 (cpm2), disrupted in the allene oxide cyclase (AOC) gene, for insights into the role of JA under drought. The mutant had higher stomatal conductance, higher water use efficiency and higher shoot ABA levels under severe drought as compared to the WT. Notably, roots of cpm2 were better developed compared to the WT under both, control and drought stress conditions. Root proteome was analyzed using the Tandem Mass Tag strategy to better understand this difference at the molecular level. Expectedly, AOC was unique but notably highly abundant under drought in the WT. Identification of other differentially abundant proteins (DAPs) suggested increased energy metabolism (i.e., increased mobilization of resources) and reactive oxygen species scavenging in cpm2 under drought. Additionally, various proteins involved in secondary metabolism, cell growth and cell wall synthesis were also more abundant in cpm2 roots. Proteome-guided transcript, metabolite, and histological analyses provided further insights into the favorable adaptations and responses, most likely orchestrated by the lack of JA, in the cpm2 roots. Our results in cpm2 are discussed in the light of JA crosstalk to other phytohormones. These results together pave the path for understanding the precise role of JA during drought stress in rice

Chemohormonal Therapy in Metastatic Hormone-Sensitive Prostate Cancer: Long-Term Survival Analysis of the Randomized Phase III E3805 CHAARTED Trial
Purpose
Docetaxel added to androgen-deprivation therapy (ADT) significantly increases the longevity of some patients with metastatic hormone-sensitive prostate cancer. Herein, we present the outcomes of the CHAARTED (Chemohormonal Therapy Versus Androgen Ablation Randomized Trial for Extensive Disease in Prostate Cancer) trial with more mature follow-up and focus on tumor volume.
Patients and Methods
In this phase III study, 790 patients with metastatic hormone-sensitive prostate cancer were equally randomly assigned to receive either ADT in combination with docetaxel 75 mg/mm2 for up to six cycles or ADT alone. The primary end point of the study was overall survival (OS). Additional analyses of the prospectively defined low- and high-volume disease subgroups were performed. High-volume disease was defined as presence of visceral metastases and/or ≥ four bone metastases with at least one outside of the vertebral column and pelvis.
Results
At a median follow-up of 53.7 months, the median OS was 57.6 months for the chemohormonal therapy arm versus 47.2months for ADT alone (hazard ratio [HR], 0.72; 95% CI, 0.59 to 0.89; P = .0018). For patients with high-volume disease (n = 513), the median OS was 51.2 months with chemohormonal therapy versus 34.4 months with ADT alone (HR, 0.63; 95% CI, 0.50 to 0.79; P \u3c .001). For those with low-volume disease (n = 277), no OS benefit was observed (HR, 1.04; 95% CI, 0.70 to 1.55; P = .86).
Conclusion
The clinical benefit from chemohormonal therapy in prolonging OS was confirmed for patients with high-volume disease; however, for patients with low-volume disease, no OS benefit was discerned
An Improved Detection of Circulating Tumor DNA in Extracellular Vesicles-Depleted Plasma
Circulating tumor DNA (ctDNA) in plasma has been used as a biomarker for cancer detection and outcome prediction. In this study, we collected the five precipitates (fractions 1–5) and leftover supernatant plasma component (fraction 6) by a sequential centrifugation in plasma samples from nine small cell lung cancer (SCLC) patients. The fractions 3, 5 and 6 were large vesicles, exosomes and extracellular vesicles (EVs)-depleted plasma, respectively. Fragment size analysis using DNAs from these fractions showed dramatical differences from a peak of 7–10 kb in fraction 1 to 140–160 bp in fraction 6. To determine ctDNA content, we performed whole genome sequencing and applied copy number-based algorithm to calculate ctDNA percentage. This analysis showed the highest ctDNA content in EV-depleted plasma (average = 27.22%), followed by exosomes (average = 22.09%) and large vesicles (average = 19.70%). Comparatively, whole plasma, which has been used in most ctDNA studies, showed an average of 23.84% ctDNA content in the same group of patients. To further demonstrate higher ctDNA content in fraction 6, we performed mutational analysis in the plasma samples from 22 non-small cell lung cancer (NSCLC) patients with known EGFR mutations. This analysis confirmed higher mutation detection rates in fraction 6 (14/22) than whole plasma (10/22). This study provides a new insight into potential application of using fractionated plasma for an improved ctDNA detection
Opposing transcriptional programs of KLF5 and AR emerge during therapy for advanced prostate cancer.
Endocrine therapies for prostate cancer inhibit the androgen receptor (AR) transcription factor. In most cases, AR activity resumes during therapy and drives progression to castration-resistant prostate cancer (CRPC). However, therapy can also promote lineage plasticity and select for AR-independent phenotypes that are uniformly lethal. Here, we demonstrate the stem cell transcription factor Krüppel-like factor 5 (KLF5) is low or absent in prostate cancers prior to endocrine therapy, but induced in a subset of CRPC, including CRPC displaying lineage plasticity. KLF5 and AR physically interact on chromatin and drive opposing transcriptional programs, with KLF5 promoting cellular migration, anchorage-independent growth, and basal epithelial cell phenotypes. We identify ERBB2 as a point of transcriptional convergence displaying activation by KLF5 and repression by AR. ERBB2 inhibitors preferentially block KLF5-driven oncogenic phenotypes. These findings implicate KLF5 as an oncogene that can be upregulated in CRPC to oppose AR activities and promote lineage plasticity
