To explore the relationship between 3D power Doppler ultrasound (3D-PDU) and serum MMP-2 and Ang-2 levels in pregnant women with preeclampsia (PE).

Comparative analytical study.

The Second Affiliated Hospital and Yuying Children's Hospital of Wenzhou Medical University, China, from October 2017 to January 2020.

One hundred and thirty-four pregnant women with PE were selected as the research subjects, with 67 cases in mild group and 67 cases in severe group. Sixty-seven healthy primigravidas were selected as normal control group. Serum MMP-2 and Ang-2 were detected. All subjects underwent prenatal 3D-PDU examination, and VI, FI and VFI were measured.

Compared to normal control group, serum MMP-2 and Ang-2 levels of mild group and severe group decreased successively (all p <0.001); VI, FI, and VFI of mild group and severe group decreased successively (both p <0.001). Pearson correlation analysis showed that serum MMP-2 in pregnant women with PE was positively correlated with VI, FI, VFI (r = 0.940, p <0.001, r = 0.938, p <0.001, and r = 0.921, p <0.001, respectively); and serum Ang-2 was positively correlated with VI, FI, VFI (r = 0.958, p <0.001; r = 0.960; p <0.001; r = 0.945, p <0.001, respectively).

3D-PDU has a certain application value in the diagnosis of pregnant women with PE, variation tendency of VI, FI and VFI detected by 3D-PDU is closely associated with serum MMP-2 and Ang-2 levels. Key Words Preeclampsia, Pregnant women, MMP-2, Ang-2, 3D power Doppler ultrasound (3D-PDU).

To compare the effectiveness of bubble continuous positive airway pressure (bCPAP) and oxygen inhalation via nasal cannula in neonates presenting with respiratory distress, using Silverman Anderson Retraction Score (SARS).

Randomised clinical trial.

Department of Paediatrics, Unit-1, KEMU/Mayo Hospital, Lahore, Pakistan, from April 2017 to June 2018.

A total of 120 neonates fulfilling inclusion and exclusion criteria were enrolled and were randomly allocated in two groups Group A and Group B. In group A, neonates were given bCPAP for respiratory support, while neonates in group B were given nasal oxygen as control group. Oligomycin A purchase Neonates in both groups were followed for 48 hours. The effectiveness was determined by the reduction in SARS, up to or less than score 3, at the end of a 48-hour period. Data were collected and analysed by SPSS version 20.0. P-value ≤0.05 was taken as significant.

In Group A, effectiveness was found to be 93.3%, and in Group B effectiveness was 71.7% (p = 0.003). Median reduction in SARS from 00 to 48 hours, in group A (bCPAP) was 4 (4 - 5) while in group B (control), it was 3 (2 - 3); statistically significant (p <0.001).

Bubble CPAP was more effective than nasal oxygen alone, in treatment of respiratory distress among neonates. This study suggested that bCPAP should be used more frequently in NICUs of Pakistan to reduce burden of neonatal morbidity due to respiratory distress. Key Words Bubble CPAP, Respiratory distress, Neonates, Silverman Anderson Retraction Score.

To determine the percentage of seroconverted real time reverse transcriptase polymerase chain reaction (RT-PCR) positive coronavirus disease (COVID-19) cases at different days post-symptom onset; and also find the agreement of chemiluminescence assay used for total antibody detection using RT-PCR as a reference method.

Cross-sectional study.

Chughtai Institute of Pathology from April to May 2020.

Fifty pre-pandemic samples (healthy population) and 75 COVID-19 patients were included in the study. RT-PCR confirmed COVID-19 patients were divided into 3 equal groups (25 each), according to the days of symptom onset. The samples were analysed using electro-chemiluminescence as assay principle. Positive and negative agreement of COVID-19 antibodies was calculated using EP evaluator to find out the sensitivity of chemiluminescence assay for total antibody detection. The results were analysed using SPSS version 23.0.

All the pre-pandemic samples tested were negative for antibodies with a negative agreement of 100%. Total agreement at day 7 post-symptom onset was 84%; whereas, it was 94% at day 14 and increased rapidly to 100% at day 21 post-symptom onset. At day 7 post-symptom onset, 68% of patients were seroconverted; and this percentage was 88% and 100% at day 14 and 21 post-symptom onset, respectively.

Pre-pandemic samples were non-reactive for COVID-19 antibodies and seroconversion started within the first week post-virus exposure. There was 100% concordance between RT-PCR result and antibody positivity 21 days post-symptom onset. Key Words COVID-19, SARS CoV-2, Seroconversion, Chemiluminescence.

Cross-sectional comparative study.

King Edward Medical University (KEMU) and Doctors Hospital Lahore, from December 2018 to February 2019.

Patients of both genders and all age groups with thrombocytopenia presenting for bone marrow biopsy were included in the study. Clinical data, complete blood count (CBC) sample in EDTA, bone marrow aspirate and trephine biopsy were obtained. Slides were prepared and reviewed. CBC sample was analysed for counts and IPF in Doctors Hospital Laboratory within 4 hours of collection.

According to bone marrow findings, patients were grouped under two categories; Group 1 with central (hypo-productive group) thrombocytopenia and Group 2 with peripheral (hyper-destructive group). Group1 (n=44) showed median interquartile range (IQR) IPF 8.
