ABSTRACT
Infection with the SARS-CoV-2 virus may induce some complications among people who experience mild to moderate respiratory illness and some of them recover without requiring special treatment. Albeit, some individuals become seriously reached risk points and require special medical attention especially older people and people who suffer from chronic diseases. Serum and whole blood samples were collected from confirmed infected persons with SARS CoV-2 by real-time PCR and the control group. All lab. Investigations were performed using Cobas 6000. Significant differences were noted between patients compared to the control group in the Mean ± SD of IL-6 (76.06 ± 7.60 vs 3.61 ± 0.296 pg/ml), Procalcitonin (0.947 ± 0.117 vs 0.061 ± 0.007 ng/ml), CRP (125.3 ± 7.560 vs 4.027 ± 0.251 mg/dl), ALT (154.8 ± 30.47 vs 49.75 ± 2.977 IU/L) and AST (70.83 ± 9.215 vs 27.23 ± 1.767) respectively. While other parameters were also showed significant differences were noted between patients compared to the control group for D-Dimmer, PT, PTT, LDH, Ferritin, WBC, Lymphocyte and Creatinine. The results reached that the effect of SARS CoV-2 and cytokine storm was clear on the body's organs through vital biomarker investigations that were performed in this study.
ABSTRACT
Euphorbia prostrata (E. prostrata) and Crotalaria burhia (C. burhia) are widely found in flora of the Cholistan Desert of Bahawalpur, Pakistan and are traditionally used to treat pain and chronic disease. The current study aimed to evaluate their phytochemical screening, antioxidant activity, in-vivo phagocytic activity, and analgesic activity. Both the plant extracts were investigated for phytochemical screening, Fourier Transform Infrared (FTIR) analysis, in-vitro antioxidant by 2, 2-diphenyl-1-picrylhydrazyl (DPPH) method, in-vivo immunomodulatory activity by macrophages phagocytosis using carbon clearance rate assay and analgesic activity by acetic acid produced writhing method. Phytochemical screening showed the presence of carbohydrates, saponins, tannins, phenols, quinines, proteins, terpenes, glycosides, and alkaloids. FTIR analysis revealed the existence of different functional groups in both extracts. The DPPH method showed that E. prostrata exhibited a high antioxidant potential with an IC50 of 62.5 µg/ml whereas C. burhia showed a lower antioxidant potential. At the dose of 200 mg/kg body weight (b. wt), both the extracts showed a significant increase in the phagocytic index by 5.2 ± 0.2, and, 4.8 ± 0.1 (p < 0.001) respectively which was close to the 100 mg/kg b. wt of the standard drug (Levamisole) 5.4 ± 0.2. Both the extracts at the dose of 200 mg/kg b. wt also significantly reduced the writhing (abdominal contractions) count by 13.7 ± 0.3 and, 25.3 ± 1.5 (p < 0.001), showing 71.8% and 47.6% of reduced analgesic activity compared to the standard drug dicloran (diclofenac sodium), respectively. In conclusion, extracts of both plants indicate their role in the management of various disorders to relieve pain and modulate the immune system.
ABSTRACT
The need for an effective health personnel team is important due to the increasing complexity of patient care and increasing co-morbidities. Interprofessional collaboration (IPC) among healthcare professionals offers appropriate collaborative management for humans. This study aimed to assess the attitude and barriers to IPC in hospitals among healthcare professionals in Lahore, Pakistan. A cross-sectional study was conducted using a convenience sampling technique. Healthcare professionals (speech-language pathologists, audiologists, physiotherapists, occupational therapists, psychologists, psychiatrists, neurologists, ENT specialists, pediatricians, dentists, and nursing staff) working at Children Hospital, Shaikh Zayed Hospital, Pakistan Society for the Rehabilitation of the Disabled (PSRD), Lahore, Pakistan were included. The paper and online survey questionnaire composed in the google form and attitudes toward healthcare teams scale (ATHCT) and barriers scale toward interprofessional collaboration were used. Statistical package for the social sciences (SPSS) version 21 was used to analyze the survey data through frequency analyses and percentage distributions. Most of the respondents (response rate = 88.1%) had positive attitudes toward IPC and strongly agreed on 9 positive statements in ATHCT. Statistically, Major barriers were role and leadership ambiguity 68.6%, different goals of individual team members 68.1%, and 53.3% strongly agreed on the difference in levels of authority, power, expertise, and income. Although healthcare professionals have an optimistic attitude toward IPC, several healthcare professionals come across challenges during the practice of IPC. To overcome the analyzed barriers, the higher healthcare authorities must encourage interprofessional collaborative strategies and models.

In recent years, several deep learning models have been proposed to accurately quantify and diagnose cardiac pathologies. These automated tools heavily rely on the accurate segmentation of cardiac structures in MRI images. However, segmentation of the right ventricle is challenging due to its highly complex shape and ill-defined borders. Hence, there is a need for new methods to handle such structure's geometrical and textural complexities, notably in the presence of pathologies such as Dilated Right Ventricle, Tricuspid Regurgitation, Arrhythmogenesis, Tetralogy of Fallot, and Inter-atrial Communication. The last MICCAI challenge on right ventricle segmentation was held in 2012 and included only 48 cases from a single clinical center. As part of the 12th Workshop on Statistical Atlases and Computational Models of the Heart (STACOM 2021), the M&Ms-2 challenge was organized to promote the interest of the research community around right ventricle segmentation in multi-disease, multi-view, and multi-center cardiac MRI. Three hundred sixty CMR cases, including short-axis and long-axis 4-chamber views, were collected from three Spanish hospitals using nine different scanners from three different vendors, and included a diverse set of right and left ventricle pathologies. The solutions provided by the participants show that nnU-Net achieved the best results overall. However, multi-view approaches were able to capture additional information, highlighting the need to integrate multiple cardiac diseases, views, scanners, and acquisition protocols to produce reliable automatic cardiac segmentation algorithms.

Varicose veins are convoluted, expanded, and stretched subcutaneous veins of the lower leg and are the most frequently reported medical condition. This condition has a higher prevalence in Western and developed countries. Inadequacy of the valves results in reflux of blood in the veins of the lower leg. The present study aims to describe the epidemiology and contributing factors (risk factors and pathological factors) in the development of varicose veins disease. PubMed/Medline, Science Direct, Google Scholar, SciFinder, Scopus, and Web of Science databases were explored to include potential research and review articles. Finally, 65 articles were considered appropriate to include in the study. Pain, swelling, heaviness, and tingling of the lower limbs are the most common sign and symptoms caused by varicose veins while in some individuals it is asymptomatic. The Prevalence of varicose veins varies geographically. Currently, it is reported that globally about 2%-73% of the population is affected by varicose veins while the prevalence rate in Pakistan is 16%-20%. Different risk factors associated with the advancement of varicose veins are age, gender, occupation, pregnancy, family history, smoking, BMI and obesity, exercise, genetic factor, and current lifestyle. In varicose veins, some contributory elements may also play an important role in the disease development, incorporating constant venous wall aggravation, hereditary variation, and persistent venous hypertension. This condition has now turned into a curable issue that was previously viewed broadly as less important for treatment, determining the individual's satisfaction. Moreover, the mechanisms behind the risk factors involve diet, physical work, and hormonal contribution. These are more likely to be explored.
ABSTRACT
Background: Colchicum autumnale, Strychnous nux-vomica and Aloe barbadensis are the medicinal plants clinically utilized for the management of rhuematic disorders. Purpose: The present work was focused to evaluate the in-vitro anti-arthritic and anti-inflammatory activities of Colchicum (Colchicum autumnale), Nux-vomica (Strychnous nux-vomica), and Aloe-vera (Aloe barbadensis). Research Design: Primarily, the aqueous-ethanolic extracts of these medicinal plants were phytochemically screened followed by Fourier Transform Infrared (FTIR) analysis. Anti-arthritic activity by protein denaturation method and anti-inflammatory activity by human red blood cell (HRBC) membrane stabilization method at the concentration of 125, 250, and 500 µg/mL along with standard were performed. Results: Phytochemical screening revealed that alkaloids, saponins, terpenoids, phenols, and anthraquinones were found in all the extracts, and organic acids, amine group, aromatic or aliphatic compounds, esters and halogens, and phenolics were identified by FTIR. Protein denaturation method revealed that colchicum, nux-vomica, and aloe-vera showed maximum 98.5%, 99.6%, and 72.3% of inhibition at 500 µg/mL compared with that of standard drug, that is, Diclofenac sodium. Membrane stabilization method showed that colchicum, nux-vomica, and aloe-vera showed maximum 40.20%, 35.67%, and 40.1% protection at 500 µg/mL when compared with standard drug. Conclusion: It is concluded from the current study that extracts of colchicum, nux-vomica, and aloe-vera showed more potent effect and thus can be used as alternative options for the management of inflammatory and arthritic ailments.
ABSTRACT
IEEE 802.15.4 based Wireless Personal Area Networks (WPANs) are envisioned to play a vital role in the application centric ubiquitous networks. In IEEE802.15.4 networks, the use of non-interfering logical channels in multiple PANs, operating in a Personal Operating Space (POS) ensures to control the scope of PAN-directed broadcasts, reduce received energy per PAN device, and minimize interference at the physical layer. At the downside the inter-PAN communication is not possible with this setup as PANs in the same region remain unaware of each other's presence. This situation hinders sharing information of common interest amongst PANs and accessing infrastructure networks hopping through multiple PANs. In this paper, we present a comprehensive architecture enables neighboring PANs to communicate by diffusing into each other through border nodes. The basic idea is to time share logical channels to perform a gating operation by border nodes. Our contribution includes detection of border nodes, discovery of neighboring PAN(s), a common channel based gating protocol, interest diffusion and inter-PAN data transfer. We mathematically analyze the proposed architecture and carry out simulations in Network Simulator (ns2) for performance evaluation. Our simulations show that the proposed architecture gives optimal performance when multiple border nodes are able to perform gating.
