Objectives: To identify association of neutrophil to lymphocyte ratio with disease severity and mortality.
Methods: Total 720 Corona Virus RT-PCR positive patients were included in this cross-sectional study. Patients were admitted to KRL Hospital Islamabad from April 2020 to August 2020. Neutrophil to lymphocyte ratio (NLR) was recorded on admission and then serially. NLR cut-off was 3.0. WHO categories for disease severity (asymptomatic, mild, moderate and severe) were used. Demographic profile, symptoms and co-morbidities were recorded.
Results: The mean age of patients was 40 ± 12.4 years with 96% being males. Majority patients (76.5%) were asymptomatic. Amongst symptoms, fever was the most common symptom. Diabetes mellitus was most common recorded co-morbidity. The mean NLR 2.5 ± 2.78. Significant association was found between NLR and disease severity as well as mortality. Difference in mean NLR amongst disease severity categories was also significant.
Conclusion: Results are compatible with worldwide studies and NLR is a cheap and easily available marker of disease severity and mortality.

Susceptibility of different mice species to chemical induction of colorectal cancer by 1,2-dimethylhydrazine.

Department of Biochemistry, Faculty of Pharmacy, Cairo University, Cairo, 11562, Egypt.
Background: Colorectal cancer (CRC) is a major public health concern. Animal models play a crucial role in understanding the disease pathology and development of effective treatment strategies. Chemically induced CRC represents a cornerstone in animal model development; however, due to the presence of different animal species with different genetic backgrounds, it becomes mandatory to study the susceptibility of different mice species to CRC induction by different chemical entities such as 1,2-dimethylhydrazine (DMH).

Background: Nonpharmaceutical interventions for coronavirus disease (COVID-19), caused by severe acute respiratory syndrome coronavirus 2, during the pandemic altered the epidemiology of respiratory viruses. This study aimed to determine the changes in respiratory viruses among children hospitalized from 2018 to 2023.
Methods: Nasopharyngeal specimens were collected from children aged under 15 years with fever and/or respiratory symptoms admitted to a medical institution in Fukushima Prefecture between January 2018 and December 2023.
Circulating MicroRNAs in Patients with Psoriasis Treated with Anti-IL-23: A Cohort Study.
Dermatol Ther (Heidelb)

Department of Clinical and Molecular Sciences (DISCLIMO), Università Politecnica delle Marche, Ancona, Italy.
Introduction: Psoriasis is characterized by aberrant keratinocyte activity and immune cell infiltration, driven by immune-mediated pathways. MicroRNAs (miRNAs) play crucial roles in regulating these processes, offering insights into disease mechanisms and therapeutic targets.
Objectives: This study aimed to investigate changes in circulating miRNAs in psoriasis patients undergoing risankizumab therapy, an anti-IL-23 monoclonal antibody, to understand its impact on disease pathogenesis and treatment response.
Preliminary observations in cortical excitability changes using transcranial magnetic stimulation (TMS), it's correlation with diffusion tensor imaging (DTI) in subjects with neuromyelitis optica spectrum disorder (NMOSD).

Department of Neurology, National Institute of Mental Health & Neurosciences, Bangalore, 560029, India.
Background: Neuromyelitis optica spectrum disorder (NMOSD) is a relapsing central nervous system disease most commonly associated with aquaporin-4 antibodies (AQP4-Ab) and Myelin oligodendrocyte glycoprotein (MOG) antibodies. These demyelinating disorders influence cortical excitability, which has been studied using advanced imaging techniques and transcranial magnetic stimulation (TMS) in our study.
Methods: This is a prospective study of 30 subjects.
Background/objectives: Sepsis-related acute kidney injury (SA-AKI) is a severe condition characterized by high mortality rates. The utility of the sCAR (secrum creatinine/albumin) and LAR (Lactate dehydrogenase/albumin) as diagnostic markers for persistent severe SA-AKI remains unclear.
Methods: We acquired training set data from the MIMIC-IV database and validation set data from the First Affiliated Hospital of Harbin Medical University.
