Background: Pakistan reported 1.57 million COVID-19 cases between 2020 and 2022, based on approximately 30.6 million SARS-CoV-2 RT-PCR (reverse-transcription polymerase chain reaction) tests conducted.

Tumour boards are meetings where physicians from various disciplines treating cancer patients meet to recommend evidence-based or the best possible treatment plan. These meetings have evolved with time and now, in every part of the world; site-specific multi-disciplinary tumour boards are established. These meetings are considered pivotal for improving patient outcomes.

The incubation with seminal plasma significantly reduced the percentage of progressively motile spermatozoa as well as the proportion of medium progressive spermatozoa whilst increasing the percentage of non-progressive spermatozoa. The centrifugation procedure improved the sperms' kinematic parameters, and the highest values were observed for samples centrifugated with cushion fluid.

Mutations in FLT3 and nucleophosmin (NPM) genes are the most frequent genetic abnormalities, which are also known to impact disease outcomes. FLT3 mutations have been identified in approximately 30% of AML patients and are associated with poor prognoses.

Report the spectrum of monogenic disorders in our cohort.
Methods: Medical records of women consulting prenatal genetic counselling clinic at Aga Khan University Hospital, Karachi from December-2015 to March-2021 with history of miscarriage or a monogenic disorder in previous children were reviewed.
COVID-19 resulted in extensive morbidity and mortality worldwide. SARS-CoV-2 evolved rapidly, with increasing transmission due to Variants of Concern (VOC). Identifying VOC became important but genome submissions from low-middle income countries (LMIC) remained low leading to gaps in genomic epidemiology.

Gastrointestinal tract involvement is very rare and may be difficult to diagnose. Its recognition is crucial as prognostic ramifications are different.

Genomic sequencing provides robust information but may not always be accessible, and therefore, mutation-based polymerase chain reaction (PCR) approaches can be used for rapid identification of known variants. International travelers arriving in Karachi between December 2020 and February 2021 were tested for SARS-CoV-2 by PCR.

Materials And Methods: We studied ninety SARS-CoV-2 strains isolated between March and October 2020. Whole genome sequences from our laboratory and available genomes were used to investigate phylogeny, genetic variantion and mutation rates of SARS-CoV-2 strains in Pakistan.
Objective: We investigated the discrepancy between clinical and PCR-based diagnosis of COVID-19. We compared results of ten patients with mild to severe COVID-19. Respiratory samples from all cases were tested on the Roche SARS-CoV-2 (Cobas) assay, Filmarray RP2.

Thus, we describe the frequency and distribution of CXR findings, and their association with clinical outcomes of patients with COVID-19.
Methods: All adult (≥ 18 years) patients presenting between 28th February-31st May to the emergency department of a tertiary care hospital in Pakistan, who were COVID-19 positive on RT-PCR with CXR done on presentation, were included.
Duchenne muscular dystrophy (DMD) and Becker muscular dystrophy (BMD) are inherited X-linked recessive genetic disorders caused by defects in the dystrophin gene. Abnormality in the dystrophin protein causes progressive muscle damage and weakness leading to long-term disability. To investigate the spectrum of dystrophin gene variants (deletions and duplications) in Pakistani patients suspected of having DMD/BMD or of being DMD/BMD carriers.
