Effects of SARS Cov-2 epidemic on the obstetrical and gynecological emergency service accesses. What happened and what shall we expect now?

OBJECTIVE: During the lockdown period, the fear about the risk of infection in hospital has reduced the admission to Emergency Services (ES) with possible negative health effects. We have investigated the changes in the emergency flow occurred during SARS-CoV-2 pandemic in an obstetrics and gynecological ES and the short-term adverse outcomes on women's and reproductive health. STUDY DESIGN: The study was conducted in the OBGYN ES of the Clinica Mangiagalli, the largest maternity clinic of Milan, Lombardy, Northern Italy. We analyzed retrospectively the records of all women consecutively admitted at the ES from February 23rd to June 24th 2019, and compared them with the admissions during the lockdown executive order from February 23rd to June 23rd, 2020. Patients were assessed in terms of demographic features, presentation times, triage classification (urgent/not urgent), reason for admission and outcome of the visit (discharge/admission to the ward). A total of 9291 data were retrieved from ES files and automation system, 5644 from 2019 and 3647 from 2020. Categorical variables were compared by the chi-square test calculating the p value and computed were percentage changes (with 95 % Confidence interval, CI). RESULTS: During the period February 24 th - May 31 th 2020 the admissions at the ES decreased by 35.4 % (95 % CI-34.1-36.6) compared with the corresponding period in 2019. The reduction was more marked for gynecological complaints (-63.5 %, 95 %CI -60.5 to -66.5): in particular we observed a reduction of admissions for genital infection/cystitis of 75.7 % (95 %CI -71.4 to -80.1). The admission for complaints associated with pregnancy decreased by 28.5 % (95 %CI -27.2 to-29.9). In the index period, five fetal deaths were diagnosed compared with one observed in the reference period in 2019 (chi square computed using as denominator all observed pregnancies = 4.29, p = 0.04). The frequency of admission for elective caesarean section/labor induction increased from 47.5 % in 2019 to 53.6 % in 2020: this difference was statistically significant. CONCLUSION: The lockdown negatively influenced ES admissions and consequently the women's/reproductive health. As possible short-term consequences, we observed an increase of intrauterine deaths and a decrease of natural births.

Skin-to-skin contact and delivery room practices: a longitudinal survey conducted in Piedmont and the Aosta Valley.

BACKGROUND: Sudden unexpected postnatal collapse of presumably healthy neonates during early skin-to-skin contact is a rare, yet recognized occurrence, associated with a high risk of mortality and morbidity. A survey was conducted in 2012 in 30 delivery wards throughout Piedmont and the Aosta Valley to evaluate the environmental and logistical aspects that could be linked to SUPC. The survey was again conducted in 2016 in 28 delivery wards in Piedmont and the Aosta Valley in order to evaluate organizational improvements introduced after ministerial indications and recommendations by the Italian Society of Neonatology were published in 2014, in light of new findings regarding the phenomenon. METHODS: A questionnaire specifically asking about the organization of delivery wards, and surveillance or supervision during early skin-to-skin contact, was sent to all of the hospitals taking part in the survey in both 2012 and 2016. The collected data were elaborated anonymously and the statistical analysis was performed by using the two by two table. RESULTS: In 2012, 28 out of 30 delivery wards in Piedmont and Aosta, with a total of 31,074 newborns out of 35,435, were evaluated in all of the environmental and logistical aspects that might be cause for SUPC to occur. An identical survey was taken again in 2016; 26 out of 28 wards participated with a total of 27,484 newborns out of 30,339. In 2012, early skin-to-skin contact took place immediately in all the delivery rooms in 27 wards, and soon after in the post-partum room in one; in 11 out of 28 wards there was early skin-to-skin contact in the operating theater itself, following caesarean sections (11/26 in 2016). Routine newborn care was given after 3 h in 8 delivery wards (7/26 in 2016); after 2 h in 12 (7/26 in 2016); after 1 h in 2 (4/26 in 2016); after 30 min in 3 (2/26 in 2016); after 10 min in 1 (0/26 in 2016); after 1 or 2 min in 1 (0/26 in 2016) and at any time in one ward (6/26 in 2016). CONCLUSION: Periodic surveys of delivery wards are useful for the assessment of all the aspects and risk factors that need to be changed in order to implement safe early skin-to-skin contact.

Electrolyte abnormalities in cystic fibrosis: systematic review of the literature.

BACKGROUND: Cystic fibrosis per se can sometimes lead to hyponatremia, hypokalemia, hypochloremia or hyperbicarbonatemia. This tendency was first documented 60 years ago and has subsequently been confirmed in single case reports or small case series, most of which were retrospective. However, this issue has not been addressed analytically. We have therefore systematically reviewed and analyzed the available literature on this subject. METHODS: This was a systematic review of the literature. RESULTS: The reports included in this review cover 172 subacute and 90 chronic cases of electrolyte imbalances in patients with cystic fibrosis. The male:female ratio was 1.57. Electrolyte abnormalities were mostly associated with clinically inapparent fluid volume depletion, mainly affected patients aged ≤2.5 years, frequently tended to recur and often were found before the diagnosis of cystic fibrosis was established. Subacute presentation often included an history of heat exposure, vomiting, excessive sweating and pulmonary infection. History of chronic presentation, in contrast, was often inconspicuous. The tendency to hypochloremia, hypokalemia and metabolic alkalosis was similar between subacute and chronic patients, with hyponatremia being more pronounced (P < 0.02) in subacute compared to chronic presentations. Subacute cases were treated parenterally; chronic ones were usually managed with oral salt supplementation. Retention of urea and creatinine was documented in 38 % of subacute cases. CONCLUSIONS: The findings of our review suggest that physicians should be aware that electrolyte abnormalities can occur both as a presenting and a recurring feature of cystic fibrosis.

Free and total plasma malondialdehyde in chronic renal insufficiency and in dialysis patients.

BACKGROUND: Available data about oxidative status in patients with end-stage renal disease (ESRD) or on dialysis are contradictory. The present cross-sectional study aimed to investigate the role of renal insufficiency and dialysis on lipid peroxidation. To separate the effects of uraemia from dialysis-induced stress, we enrolled 26 patients with renal insufficiency on conservative treatment (ESRD), 23 on peritoneal dialysis (PD), 30 on haemodialysis (HD) and 30 controls. METHODS: Plasma malondialdehyde (MDA) levels, both total (tMDA) and free (fMDA), were measured as indexes of oxidative stress by gas chromatography-mass spectrometry. Bound MDA (bMDA) levels were calculated as the difference between tMDA and fMDA. RESULTS: Total and bMDA concentrations were significantly higher in patients than in controls (ESRD > HD > PD). In PD and HD patients, fMDA levels were similar and significantly higher than in ESRD. Multivariate analysis, with tMDA, fMDA and bMDA as dependent variables, showed similar and significant tMDA and bMDA relations with residual renal function (t = -2.160, P = 0.035) and albumin (t = -2.049, P = 0.045). Erythropoietin dose affected only fMDA values (t = -2.178, P = 0.034). CONCLUSIONS: Free and bMDA concentrations identified different MDA patterns. Bound MDA, not excreted by kidneys, accounts alone for high tMDA concentrations in ESRD patients, while both fMDA and bMDA contribute to tMDA values in dialysis patients. These findings show that increased tMDA could be indicative not only of recent lipid peroxidation, and they also highlight the importance of evaluating free, bound and total MDA in patients with reduced renal function in order to assess their oxidative status.

Increased free malondialdehyde concentrations in smokers normalise with a mixed fruit and vegetable juice concentrate: a pilot study.

BACKGROUND: Cigarette smoking, a cardiovascular risk factor leading to oxygen free radical formation, is involved in the development of serious pathological conditions. On the other hand, a healthy diet and adequate supplementation can help prevent many diseases. The aim of our study was to evaluate in healthy light smokers the effects of supplementation with mixed fruit and vegetable juice powder concentrate on homocysteine metabolism and oxidative status. METHODS: In this pilot study, 32 healthy volunteers, 16 light smokers and 16 non-smokers, on twice daily supplementation were monitored at time zero and after 30 days. Plasma homocysteine, and serum vitamin B(12) and folate concentrations were measured by immunoenzymatic assays; reactive oxygen species, total antioxidant capacity and thiol groups by spectrophotometric methods; and total and free malondialdehyde concentrations by gas chromatography-mass spectrometry with isotopic dilution. RESULTS: Baseline free malondialdehyde concentrations were significantly higher in smokers than in non-smokers and normalised after 30-day supplementation. Baseline results for all the other parameters remained unchanged after supplementation, with no significant differences between smokers and non-smokers. CONCLUSION: This is the first study showing a significant decrease in free malondialdehyde levels in light smokers after 1-month phytonutrient supplementation.
