Prevalence of newly detected diabetes in pregnancy in Qatar, using universal screening.

Diabetes first detected during pregnancy is currently divided into gestational diabetes mellitus (GDM) and diabetes mellitus (DM)- most of which are type 2 DM (T2DM). This study aims to define the prevalence and outcomes of diabetes first detected in pregnancy based on 75-gram oral glucose tolerance test (OGTT)using the recent WHO/IADPSG guidelines in a high-risk population. This is a retrospective study that included all patients who underwent a 75 g (OGTT) between Jan 2016 and Apr 2016 and excluded patients with known pre-conception diabetes. The overall prevalence of newly detected diabetes in pregnancy among the 2000 patients who fulfilled the inclusion/exclusion criteria was 24.0% (95% CI 22.1-25.9) of which T2DM was 2.5% (95% CI 1.9-3.3), and GDM was 21.5% (95% CI 19.7-23.3). The prevalence of newly detected diabetes in pregnancy was similar among the different ethnic groups. The T2DM group was older (mean age in years was 34 ±5.7 vs 31.7±5.7 vs 29.7 ±5.7, p<0.001); and has a higher mean BMI (32.4±6.4 kg/m2 vs 31.7±6.2 kg/m2 vs 29.7± 6.2 kg/m2, p< 0.01) than the GDM and the non-DM groups, respectively. The frequency of pre-eclampsia, pre-term delivery, Caesarean-section, macrosomia, LGA and neonatal ICU admissions were significantly higher in the T2DM group compared to GDM and non-DM groups. Diabetes first detected in pregnancy is equally prevalent among the various ethnic groups residing in Qatar. Newly detected T2DM carries a higher risk of poor pregnancy outcomes; stressing the importance of proper classification of cases of newly detected diabetes in pregnancy.The authors received no specific funding for this wor

Serosal and Endometrial Reconstitution During Myomectomy

Context: Myomectomy is usually performed when uterine fibroids are associated with infertility. Serosal and endometrial reconstitution are some of the subtle challenges that the gynaecologist has to deal with during myomectomy, in an attempt to minimise postoperative pelvic and intrauterine adhesions. Objective: This study was conducted to evaluate the effect of careful apposition of the serosa and endometrium on subsequent development of post-myomectomy pelvic and intrauterine adhesions and to assess the effect of resection of redundant endometrium on subsequent menorrhagia. Study Design, Setting, and Subjects: A review of 17 patients with previous myomectomy who eventually had a subsequent laparotomy for various indications between June 1992, and July 1998 in the University College Hospital, Ibadan was carried out. Main Outcome Measures: Operative findings at myomectomy, as well as therapeutic procedures performed on them were recorded. Patients' observation of changes in menstrual blood loss postoperatively was also recorded. The presence of pelvic adhesions at re-laparotomy and intrauterine adhesions on hysterosalpingography in those who had endometrial reconstitution was also noted. Results: Continuous closure was found to be beneficial in all cases of serosal defects. Excision of redundant endometrium in 11 women was associated with subjective reduction of menorrhagia in 9 of them. Conclusion: It is advisable that gynaecological surgeons strive to minimise areas of visceral trauma, ischaemia and abrasion during myomectomy.

Managing Labour in Women with COVID-19

Since first reported in December 2019 in Wuhan, China, COVID-19 caused by Severe Acute Respiratory Syndrome (SARS) Corona virus2 (SARS CoV-2) quickly spread to become a pandemic that has caused significant morbidity and mortality. The rapidity of the spread of the virus and the high mortality at the outset threatened to overwhelm health systems worldwide, and, indeed, this significantly impacted maternal health, especially since there was minimal experience to draw from. Experience with Covid 19 has grown exponentially as the unique needs of pregnant and labouring women with COVID-19 infection have become more evident. Managing COVID-19 parturients requires a multidisciplinary team consisting of anaesthesiologists, obstetricians, neonatologists, nursing staff, critical care staff, infectious disease and infection control experts. There should be a clear policy on triaging patients depending on the severity of their condition and the stage of labour. Those at high risk of respiratory failure should be managed in a tertiary referral centre with facilities for intensive care and assisted respiration. Staff and patients in delivery suites and operating rooms should be protected by enforcing infection protection principles such as offering dedicated rooms and theatres to SARS CoV-2 positive patients and using personal protective equipment. All hospital staff must be trained in infection control measures which should be updated regularly. Breastfeeding and care of the new-born must be part of the healthcare package offered to COVID-19 parturient mothers

Impact of the fear of Covid-19 infection on intent to breastfeed; a cross sectional survey of a perinatal population in Qatar

Objectives: Infection control measures during the Covid-19 pandemic have focused on limiting physical contact and decontamination by observing cleaning and hygiene rituals. Breastfeeding requires close physical contact and observance of hygienic measures like handwashing. Worries around contamination increase during the perinatal period and can be expressed as increase in obsessive compulsive symptoms. These symptoms have shown to impact breastfeeding rates. This study attempts to explore any relationship between the Covid-19 pandemic and perinatal obsessive-compulsive symptomatology and whether the Covid-19 pandemic has any impact on intent to breastfeed. Methods: A cross sectional survey of perinatal women attending largest maternity centre in Qatar was carried out during the months of October to December 2020. Socio-demographic information, intent to breastfeed and information around obsessive compulsive thoughts around Covid-19 pandemic were collected using validated tools. Results: 15.7% respondents report intent to not breastfeed. 21.4% respondents reported obsessive-compulsive symptoms. 77.3% respondents believed the biggest source of infection was from others while as only 12% of the respondents believed that the source of infection was through breastfeeding and 15.7% believed the vertical transmission as the main source of risk of transmission. Conclusions: The rates of Obsessive-compulsive symptoms were increased and the rates of intent to breastfeed were decreased when compared with pre pandemic rates. The obsessive-compulsive symptoms and the intent to not breastfeed were significantly associated with fear of infection to the new-born. Obsessive-compulsive symptoms were not significantly correlated with intent to breastfeed and can be seen as adaptive strategies utilized by women to continue breastfeeding in the context of fear of infection.The authors are grateful to the Qatar National Library for making this article available as open access.
