Objective: To compare the inter-observer reliability of Shatzker classification and Khan Classification of Tibial plateau fractures.
Methods: This retrospective cohort study was conducted at The Indus Hospital, Karachi, Pakistan. Radiographs of 50 patients who presented with tibial plateau fractures from March 2015 to November 2016 were collected. Two observers classified these cases independently according to Shatzker and Khan Classification. Gwet's AC1 statistics applied to assess inter-observer reliability of both the classification systems.
Results: Moderate inter-observer agreement for Schatzker classification (p<0.001) and slight inter-observer agreement on Khan Classification (p=0.738) was observed.
Conclusions: Khan Classification is more comprehensive in classifying tibial plateau fractures and can be used for clinical research purpose, while Shatzker classification with better inter-observer reliability is applicable for routine clinical practice.

(1) Background: Surra is a debilitating disease of wild and domestic animals caused by (), resulting in significant mortality and production losses in the affected animals. This study is the first to assess the genetic relationships of in naturally affected buffaloes from Multan district, Pakistan, using ITS-1 primers and evaluating the effects of parasitemia and oxidative stress on DNA damage and hematobiochemical changes in infected buffaloes. (2) Methods: Blood samples were collected from 167 buffaloes using a multi-stage cluster sampling strategy, and trypomastigote identification was performed through microscopy and PCR targeting RoTat 1.

Accurately identifying and discriminating between different brain states is a major emphasis of functional brain imaging research. Various machine learning techniques play an important role in this regard. However, when working with a small number of study participants, the lack of sufficient data and achieving meaningful classification results remain a challenge.

A machine learning prognostic mortality scoring system was developed to address challenges in patient selection for clinical trials within the Intensive Care Unit (ICU) environment. The algorithm incorporates Red blood cell Distribution Width (RDW) data and other demographic characteristics to predict ICU mortality alongside existing ICU mortality scoring systems like Simplified Acute Physiology Score (SAPS). The developed algorithm, defined as a Mixed-effects logistic Random Forest for binary data (MixRFb), integrates a Random Forest (RF) classification with a mixed-effects model for binary outcomes, accounting for repeated measurement data.

Ticks are the second most important hematophagous ectoparasites after mosquitoes and serve as vectors for various pathogens, transmitting them to wild and domestic animals, as well as humans. Argas persicus are the soft ticks that are known to parasitize domestic poultry. Hard ticks are known to be the reservoir of Toxoplasma (T.

Ticks, being ectoparasites, are vectors for the transmission of various pathogens that can infect animals and can also pose a significant threat to human health. Due to hot and humid climatic conditions across different agro-ecological regions of Pakistan, ticks are widespread and infest a diverse range of animal species. This study aimed for taxonomic identification and prevalence determination of ticks in sheep collected from four different marketplaces in the Quetta district of Balochistan.
