A study of proximal humerus fractures treated by PHILOS plating in a tertiary care hospital

Background: Proximal humeral fractures are commonly presented in the orthopedic practice. The usual method of treatment was conservative in the past. However, the results and functional outcomes were not good. With the development of PHILOS locking plates, the functional outcomes are known to be improved. We in the present study tried to evaluate the functional outcomes of proximal humerus fractures treated with PHILOS plates.Methods: This prospective study was conducted in all Adult patients with closed two-part and three-part fractures of the proximal humerus, those who have reported within a week of the injury were included in the study. A total of n=30 patients were included in the study based on the inclusion and exclusion criteria. A standard surgical approach with PHILOS plate was used and patients were followed up for 19 to 24 months.Results: n=30 patients out of which n=16 (53.33%) were males and n=14 (46.67%) were females. The most common age group involved in the fractures was 31-35 years n=9 (30%) of the patients. Most of the patients n=21 (70%) were having Neer's two-part fractures and three-part fractures were found in n=6 (20%) and four part in n=3 (10%). The overall results in the study were 66.67% of patients had excellent results and 16.67% had good results and 10% had poor results.Conclusions: PHILOS locking plates is a better treatment option for fractures of proximal humerus especially in cases of poor bone quality and comminuted fractures

A clinical study of surgical management of distal femur fracture using locking compression plate

Background: Fractures of distal femur are common due to increased road traffic accidents and fall from height because of increased construction activities. These fractures are quite disabling hence, these fractures necessitate early stabilization of fractures. Internal fixation with LCP has shown to give one of the best results in terms of recovery, fracture union, and clinical outcome. The aim of the study the clinical outcome of treatment of distal femur fractures using locking compression plates.Methods: A total of n=20 cases of distal femur fractures treated with LCP from December 2013 to June 2015 at NMCH and RC, Raichur. They were admitted and examined according to protocol clinically and radiologically. All patients were followed up for a minimum of 6 months and outcome assessed with Neer’s score.Results: All fractures healed with an average duration of 16 weeks which is comparable with other studies. We had two cases of varus collapse one was due to early weight bearing in one case and other case is due to gross communition. One case had an implant failure (plate breakage) due to early weight bearing. Cases needing hardware revision is comparable to other studies at 10%. Average Neer's knee score was 76.Conclusions: we have found higher Neer’s scores in this study. The LCP also prevents compression of periosteal vessels. It may not completely solve the age-old problems associated with any fracture like non-union and malunion, but is a valuable technique in the management of these fractures. But however, in type C fractures the outcome is poorer

Detecting the impact of temperature on transmission of Zika, dengue, and chikungunya using mechanistic models

Recent epidemics of Zika, dengue, and chikungunya have heightened the need to understand the seasonal and geographic range of transmission by Aedes aegypti and Ae. albopictus mosquitoes. We use mechanistic transmission models to derive predictions for how the probability and magnitude of transmission for Zika, chikungunya, and dengue change with mean temperature, and we show that these predictions are well matched by human case data. Across all three viruses, models and human case data both show that transmission occurs between 18-34°C with maximal transmission occurring in a range from 26-29°C. Controlling for population size and two socioeconomic factors, temperature-dependent transmission based on our mechanistic model is an important predictor of human transmission occurrence and incidence. Risk maps indicate that tropical and subtropical regions are suitable for extended seasonal or year-round transmission, but transmission in temperate areas is limited to at most three months per year even if vectors are present. Such brief transmission windows limit the likelihood of major epidemics following disease introduction in temperate zones

Profiling brain morphology for autism spectrum disorder with two cross-culture large-scale consortia

We explore neurodevelopmental heterogeneity in Autism Spectrum Disorder (ASD) through normative modeling of cross-cultural cohorts. By leveraging large-scale datasets from Autism Brain Imaging Data Exchange (ABIDE) and China Autism Brain Imaging Consortium (CABIC), our model identifies two ASD subgroups with distinct brain morphological abnormalities: subgroup "L" is characterized by generally smaller brain region volumes and higher rates of abnormality, while subgroup "H" exhibits larger volumes with less pronounced deviations in specific areas. Key areas, such as the isthmus cingulate and transverse temporal gyrus, were identified as critical for subgroup differentiation and ASD trait correlations. In subgroup H, the regional volume of the isthmus cingulate cortex showed a direct correlation with individuals' autistic mannerisms, potentially corresponding to its slower post-peak volumetric declines during development. These findings offer insights into the biological mechanisms underlying ASD and support the advancement of subgroup-driven precision clinical practices
