Vitamin A is a crucial micronutrient for pregnant women and their fetuses. In addition to being essential for morphological and functional development and for ocular integrity, vitamin A exerts systemic effects on several fetal organs and on the fetal skeleton. Vitamin A requirements during pregnancy are therefore greater. Vitamin A deficiency (VAD) remains the leading cause of preventable blindness in the world. VAD in pregnant women is a public health issue in most developing countries. In contrast, in some developed countries, excessive vitamin A intake during pregnancy can be a concern since, when in excess, this micronutrient may exert teratogenic effects in the first 60 days following conception. Routine prenatal vitamin A supplementation for the prevention of maternal and infant morbidity and mortality is not recommended; however, in regions where VAD is a public health issue, vitamin A supplementation is recommended to prevent night blindness. Given the importance of this topic and the lack of a complete, up-to-date review on vitamin A and pregnancy, an extensive review of the literature was conducted to identify conflicting or incomplete data on the topic as well as any gaps in existing data.
The incidence of cancer is increasing worldwide and with it the prevalence of malnutrition, which is responsible for the death of almost 20 % of cancer patients. The objective of this study was to identify the factors associated with malnutrition in hospitalized cancer patients. Cross-sectional study conducted with 277 hospitalized patients in the Institute of Integrative Medicine Prof. Fernando Figueira from March to November 2013. The nutritional status was classified as well-nourished and moderate/severe malnutrition, according to the Patient-Generated Subjective Global Assessment. The association between moderate/severe malnutrition and demographic, behavioral, socioeconomic, clinical, therapeutic and nutritional variables was investigated through univariate regression and hierarchical Poisson models, with a 5 % significance level. The prevalence of malnutrition was 71.1 %, being classified as moderate in 35.4 % and severe in 35.7 %. After multivariate analysis, smokers/ex-smokers low socioeconomic status, performance status ≥2 and age ≥60 years were associated with increased risk of malnutrition. There was observed a high prevalence of moderate/severe malnutrition in cancer patients, with the increased risk of malnutrition associated with the presence of factors that can be assessed during hospital admission suggesting a higher alert of the medical and health care staff about the need for nutritional assessment and intervention.

SARS-CoV-2, the new coronavirus of severe acute respiratory syndrome, which causes a predominantly respiratory disease called COVID-19, quickly caused a pandemic, due to its high transmissibility, leaving a trail of deaths around the world. Initially, the pregnancy puerperal cycle was not associated with complications and mortality, only later was recognized as a risk group. As the disease progressed, the maternal mortality rate by COVID-19 increased, Brazil is responsible for an important portion. This rate may be even higher due to underreporting, difficulties in performing laboratorial tests and possible false negative results and depends on the health policies adopted by each region or country. It is important to carry out studies on maternal mortality so that the prognostic factors can be recognized and so avoid them.
Background: Maternal mortality remains a major public health issue worldwide, with persistent high rates prevailing principally in underdeveloped countries. The objective of this study was to determine the risk factors for severe maternal morbidity and near miss (SMM/NM) in pregnant and postpartum women at the maternity ward of the Dom Malan Hospital, Petrolina, in northeastern Brazil. Methods: A retrospective, cohort study was conducted to evaluate the sociodemographic and obstetric characteristics of the women. Patients who remained hospitalized at the end of the study period were excluded. Risk ratios (RR) and their respective 95% confidence intervals (95% CI) were calculated as a measure of relative risk. Hierarchical multiple logistic regression was also performed. Two-tailed p-values were used for all the tests and the significance level adopted was 5%. Results: A total of 2,291 pregnant or postpartum women receiving care between May and August, 2011 were included. The frequencies of severe maternal morbidity and near miss were 17.5% and 1.0%, respectively. Following multivariate analysis, the factors that remained significantly associated with an increased risk of SMM/NM were a Cesarean section in the current pregnancy (OR: 2.6; 95% CI: 2.0 – 3.3), clinical comorbidities (OR: 3.4; 95% CI: 2.5 – 4.4), having attended fewer than six prenatal visits (OR: 1.1; 95% CI: 1.01 – 1.69) and the presence of the third delay (i.e. delay in receiving care at the health facility) (OR: 13.3; 95% CI: 6.7 – 26.4). Conclusions: The risk of SMM/NM was greater in women who had been submitted to a Cesarean section in the current pregnancy, in the presence of clinical comorbidities, fewer prenatal visits and when the third delay was present. All these factors could be minimized by initiating a broad debate on healthcare policies, introducing preventive measures and improving the training of the professionals and services providing obstetric care.
How effective is the vaginal administration of misoprostol in dilating the cervix prior to inserting an intrauterine device (IUD) in nulligravidas? The use of misoprostol at a dose of 400 µg administered vaginally 4 h prior to IUD insertion increased the ease of insertion and reduced the incidence of pain during the procedure, although the frequency of cramps increased following misoprostol use. Misoprostol has been widely used in Obstetrics and Gynecology; however, its usefulness and efficacy in facilitating IUD insertion in nulligravidas have yet to be established. The present study shows that the benefits of misoprostol use prior to IUD insertion include facilitating insertion and reducing pain during the procedure; therefore, weighing up the benefits encountered against the only negative side effect (cramps prior to insertion), these results suggest that misoprostol use should become standard practice to facilitate IUD insertion in nulligravidas. A randomized, double-blind clinical trial was conducted. Nulligravid women of reproductive age were submitted to IUD insertion between July 2009 and November 2011 at the Instituto de Medicina Integral Prof. Fernando Figueira in Recife, Pernambuco, Brazil. A total of 179 women were randomly allocated to two groups: 86 to receive 400 µg of misoprostol vaginally 4 h prior to IUD insertion and 93 to receive placebo. Risk ratios (RRs) were calculated as measures of relative risk, together with their 95% confidence intervals (95% CI). The number needed to treat (NNT) and the number needed to harm (NNH) were also calculated. Significant differences were found between the groups for all the immediate end points studied, with less difficulty in inserting the IUD [RR = 0.49 (23/86 versus 51/93); 95% CI: 0.33–0.72; P = 0.00005], a lower risk of dilatation <4 mm [RR = 0.48 (24/86 versus 54/93); 95% CI: 0.33–0.70; P = 0.0001], a reduction in moderate-to-severe pain at IUD insertion [RR = 0.56 (32/86 versus 62/93]; 95% CI: 0.41–0.76; P = 0.00008), as well as a lesser likelihood of experiencing a disagreeable or very disagreeable sensation [RR = 0.49(29/86 versus 64/93); 95% CI: 0.35–0.68; P = 0.000004] in the group that was given misoprostol compared with the group that received placebo. There was no significant difference between the groups in relation to complications during IUD insertion. There were no cases of uterine perforation in either group. The frequency of cramps was 40% higher in the misoprostol group. The present study showed a positive balance between the benefits and risks of the use of misoprostol; however, it is not feasible to conclude that its use is imperative prior to IUD insertion in nulligravidas and IUD insertion should not be canceled when the medication is unavailable. In view of its effect in promoting cervical dilatation, misoprostol may be used prior to IUD insertion both in nulligravidas and in any women with cervical stenosis irrespective of parity. This study was funded by the Instituto de Medicina Integral Prof Fernando Figueira. None.
Some studies have suggested that abdominal visceral adipose tissue depth (VAD) measured by ultrasound in early pregnancy, may predict the future onset of gestational diabetes mellitus (GDM). Wheter this is true, independent of pre-pregnancy body mass index (BMI), has been debated, leading the current study. A prospective cohort study was completed, in which VAD was measured at around 14 weeks’ gestation. GDM was later assessed by an oral glucose tolerance test at 24 to 28 weeks, according to the IADPSG criteria. Logistic regression analysis and receiver operating curve (ROC) analysis were used to estimate the predictive value of VAD, above and beyond pre-pregnancy BMI. 627 pregnant women were enrolled, and 518 completed the study. VAD was measured at a mean of 14.4 weeks’ gestation. 87 women (16.8%) subsequently developed GDM. The unadjusted odds ratio (OR) for developing GDM was 1.99 (95% CI 1.59–2.46) per 1-cm increase in VAD. After adjusting for maternal BMI and age, the OR was 2.00 (95% CI 1.61 to 2.50). The ROC under the curve for developing GDM was higher for VAD (0.70, 95% CI 0.63 to 0.75) than for pre-pregnancy BMI (0.57 95% CI 0.50 to 0.64) (p < 0.001). In conclusion, higher VAD may better predict GDM than pre-pregnancy BMI.
