Exhaled nitric oxide is associated with inflammatory biomarkers and risk of acute respiratory exacerbations in children with HIV-associated chronic lung disease.

OBJECTIVES: Chronic lung disease is a recognized complication in children with HIV. Acute respiratory exacerbations (ARE) are common among this group and cause significant morbidity. Exhaled nitric oxide (eNO) is a known marker of local airway inflammation. We investigated the association between eNO and ARE, biomarkers of systemic inflammation, and the effect of azithromycin on eNO levels. METHODS: Individuals aged 6-19 years with HIV-associated chronic lung disease in Harare, Zimbabwe, were enrolled in a placebo-controlled randomized trial investigating the effect of 48-week azithromycin treatment on lung function and ARE. eNO levels and biomarkers were measured at inclusion and after treatment in a consecutively enrolled subset of participants. Linear regression and generalized linear models were used to study associations between eNO and ARE, biomarkers, and the effect of azithromycin on eNO levels. RESULTS: In total, 172 participants were included in this sub-study, 86 from the placebo group and 86 from the azithromycin group. Participants experiencing at least one ARE during follow-up had significantly higher eNO levels at baseline than participants who did not (geometric mean ratio 1.13, 95% confidence interval [CI] 1.03-1.24, p = 0.015), adjusted for trial arm, age, sex and history of tuberculosis. Matrix metalloproteinase (MMP)-3, -7, and -10 were significantly associated with higher baseline eNO levels. At 48 weeks, azithromycin treatment did not affect eNO levels (geometric mean ratio 0.86, 95% CI 0.72-1.03, p = 0.103). CONCLUSION: Higher baseline eNO levels were a risk factor for ARE. eNO was associated with proinflammatory biomarkers previously found to contribute to the development of chronic lung disease. The potential use of eNO as a marker of inflammation and risk factor for ARE in HIV-associated chronic lung disease needs further investigation.

Women's perceptions of and experiences with the use of misoprostol for treatment of incomplete abortion in central Malawi: a mixed methods study.

BACKGROUND: Abortion-related complications are among the common causes of maternal mortality in Malawi. Misoprostol is recommended for the treatment of first-trimester incomplete abortions but is seldom used for post-abortion care in Malawi. METHODS: A descriptive cross-sectional study that used mixed methods was conducted in three hospitals in central Malawi. A survey was done on 400 women and in-depth interviews with 24 women receiving misoprostol for incomplete abortion. Convenience and purposive sampling methods were used and data were analysed using STATA 16.0 for quantitative part and thematic analysis for qualitative part. RESULTS: From the qualitative data, three themes emerged around the following areas: experienced effects, support offered, and women's perceptions. Most women liked misoprostol and reported that the treatment was helpful and effective in expelling retained products of conception. Quantitative data revealed that the majority of participants, 376 (94%) were satisfied with the support received, and 361 (90.3%) believed that misoprostol was better than surgical treatment. The majority of the women 364 (91%) reported they would recommend misoprostol to friends. CONCLUSIONS: The use of misoprostol for incomplete abortion in Malawi is acceptable and regarded as helpful and satisfactory among women.

One of the major causes of maternal mortality is complications after abortion and miscarriages. The importance of post-abortion care in preventing such deaths justifies the necessity of making treatment accessible and available to every woman in need. Misoprostol is one of the approved treatments for incomplete abortion but is rarely used in developing countries. A study was conducted in three hospitals in central Malawi where women filled in a questionnaire and were interviewed after receiving misoprostol for incomplete abortion. The study's goal was to investigate women's experiences and feelings about using misoprostol. The findings showed that the majority of the women received medication and counselling as a form of support. They expressed satisfaction with the support and described misoprostol as being useful in removing retained products of conception from the womb. The medication was preferred and regarded as a reliable treatment that was also good for women. The majority of the women reported tolerable side effects of the drug and would recommend it to friends. In conclusion, the use of misoprostol for early incomplete abortion in Malawi is acceptable and is regarded as helpful, and satisfactory to women receiving post-abortion care. The research findings support expanding use of misoprostol in post-abortion care in Malawi.

Monitoring temporal trends of dioxins, organochlorine pesticides and chlorinated paraffins in pooled serum samples collected from Northern Norwegian women: The MISA cohort study.

The ubiquitous presence of legacy and emerging persistent organic pollutants (POPs) in the environmental matrices poses a potential hazard to the humans and creating public health concerns. The present study aimed to evaluate dioxins, dioxin-like polychlorinated biphenyls (PCBs), organochlorine pesticides (OCPs) and chlorinated paraffins (CPs) concentrations in serum of women (postpartum, pregnant and non-pregnant) from Northern Norway to better understand their exposure and contamination status as well as temporal trends across 2007-2009 (MISA 1) to 2019 (MISA 2). Sixty-two blood samples from the MISA 1 cohort and 38 samples from MISA 2 were randomly selected in this study (n = 100). Ninety samples from postpartum (MISA 1) and pregnant women (MISA 2) were randomly combined into 9 pools, with 9-11 individual samples contributing to each pool keeping the groups of pregnant and postpartum women. Remaining 10 samples from non-pregnant women (MISA 2) were allocated into separate group. Geometric mean, minimum and maximum were used to describe the serum concentrations of pooled POPs in MISA cohort. Mann-Whitney U test and independent sample t-test were applied for trend analysis of blood levels of POPs between MISA 1 and MISA 2. We found the serum concentrations of selected POPs in this study to be at lower range. Serum concentrations of dibenzo-p-dioxins (PCDDs) (p = 0.010), polychlorinated dibenzofurans (PCDFs) (p = 0.002), dioxins-like PCBs (p = 0.001), hexachlorobenzene (HCB) (p < 0.001) and p,p'-dichlorodiphenyldichloroethylene (p,p'-DDE) (p = 0.002) were decreased between the studied time. In contrast, the serum concentrations of medium chain chlorinated paraffins showed an increasing trend between 2007 and 2009 and 2019 (p = 0.019). Our findings report a particular concern of emerging contaminant medium chain chlorinated paraffin exposure to humans. Future observational studies with repeated measurements of chlorinated paraffins in general populations worldwide and large sample size are warranted.

Health care providers' perceptions of using misoprostol in the treatment of incomplete abortion in Malawi.

BACKGROUND: In Malawi, abortion is only legal to save a pregnant woman's life. Treatment for complications after unsafe abortions has a massive impact on the already impoverished health care system. Even though manual vacuum aspiration (MVA) and misoprostol are the recommended treatment options for incomplete abortion in the first trimester, surgical management using sharp curettage is still one of the primary treatment methods in Malawi. Misoprostol and MVA are safer and cheaper, whilst sharp curettage has more risk of complications such as perforation and bleeding and requires general anesthesia and a clinician. Currently, efforts are being made to increase the use of misoprostol in the treatment of incomplete abortions in Malawi. To achieve successful implementation of misoprostol, health care providers' perceptions on this matter are crucial. METHODS: A qualitative approach was used to explore health care providers' perceptions of misoprostol for the treatment of incomplete abortion using semi-structured in-depth interviews. Ten health care providers were interviewed at one urban public hospital. Each interview lasted 45 min on average. Health care providers of different cadres were interviewed in March and April 2021, nine months after taking part in a training intervention on the use of misoprostol. Interviews were recorded, transcribed verbatim and analyzed using 'Systematic Text Condensation'. RESULTS: The health care providers reported many advantages with the increased use of misoprostol, such as reduced workload, less hospitalization, fewer infections, and task-shifting. Availability of the drug and benefits for the patients were also highlighted as important. However, some challenges were revealed, such as deciding who was eligible for the drug and treatment failure. For these reasons, some health care providers still choose surgical treatment as their primary method. CONCLUSION: Findings in this study support the recommendation of increased use of misoprostol as a treatment for incomplete abortion in Malawi, as the health care providers interviewed see many advantages with the drug. To scale up its use, proper training and supervision are essential. A sustainable and predictable supply is needed to change clinical practice. Unsafe abortion is a major contributor to maternal mortality worldwide. Unsafe abortion is the termination of an unintended pregnancy by a person without the required skills or equipment, which might lead to serious complications. In Malawi, post-abortion complications are common, and the maternal mortality ratio is among the highest in the world. Retained products of conception, referred to as an incomplete abortion, are common after spontaneous miscarriages and unsafe induced abortions. There are several ways to treat incomplete abortion, and the drug misoprostol has been successful in the treatment of incomplete abortion in other low-income countries. This study explored perceptions among health care providers using misoprostol to treat incomplete abortions and whether the drug can be fully embraced by Malawian health care professionals. Health personnel at a Malawian hospital were interviewed individually regarding the use of the drug for treating incomplete abortions. This study revealed that health care providers interviewed are satisfied with the increased use of misoprostol. They highlighted several benefits, such as reduced workload and that it enabled task-shifting so that various hospital cadres could now treat patients with incomplete abortions. The health care workers also observed benefits for women treated with the drug compared to other treatments. The challenges mentioned were finding out who was eligible for the drug and drug failure. This study supports scaling up the use of misoprostol in the treatment of incomplete abortions in Malawi; the Ministry of Health and policymakers should support future interventions to increase its use.

Chlorinated Paraffins in Human Milk from Urban Sites in China, Sweden, and Norway.

Short-, medium-, and long-chain chlorinated paraffins (SCCPs, MCCPs, and LCCPs) were analyzed in human milk from the Yangtze River Delta (YRD) and Scandinavia. Individual samples were collected from Shanghai, Jiaxing, and Shaoxing (China), Stockholm (Sweden), and Bodø (Norway) between 2010 and 2016. Mean concentrations (range) of SCCPs, MCCPs, and LCCPs in samples from the YRD were 124 [

"Confidence comes with frequent practice": health professionals' perceptions of using manual vacuum aspiration after a training program.

BACKGROUND: Malawi has one of the highest maternal mortality rates in the world, with unsafe abortion as a major contributor. Curettage is most frequently used as the surgical method for treating incomplete abortions, even though it is costly for an impoverished health system and the less expensive and safe manual vacuum aspiration (MVA) method is recommended. METHODS: The aim of this 2016-17 study is to explore health worker's perception of doing MVA 1 year after an educational intervention. Focus group discussions were recorded, transcribed verbatim, and analyzed using content analysis for interpreting the findings. A knowledge, attitude and practice survey was administered to health professionals to obtain background information before the MVA training program was introduced. RESULTS: Prior to the training sessions, the participants demonstrated knowledge on abortion practices and had positive attitudes about participating in the service, but preferred curettage over MVA. The training was well received, and participants felt more confident in doing MVA after the intervention. However, focus group discussions revealed obstacles to perform MVA such as broken equipment and lack of support. Additionally, the training could have been more comprehensive. Still, the participants appreciated task-sharing and team work. CONCLUSION: Training sessions are considered useful in increasing the use of MVA. This study provides important insight on how to proceed in improving post-abortion care in a country where complications of unsafe abortion are common and the health system is low on resources.

Influence of maternal and sociodemographic characteristics on the accumulation of organohalogen compounds in Argentinian women. The EMASAR study.

The occurrence of organohalogen compounds in venous serum from post-partum mothers from two Argentinian cities, Salta and Ushuaia, has been investigated (n = 698). 4,4'-DDE was the most abundant compound in these cities, with geometric means of 33 and 67ng/g lipid weight, respectively. City of residence, age and parity were the main determinants of the accumulation of these compounds. Hexachlorobenzene (HCB) was the second most abundant pollutant in Ushuaia, 8.7ng/g lipid, and ß-hexachlorocyclohexane (ß-HCH) in Salta, 7.8ng/g lipid. Decabromodiphenyl ether was higher in Ushuaia than Salta, 8.2 and 4.1ng/g lipid, respectively. The predominance of ß-HCH, 4,4'-DDE and 4,4'-DDT in Salta was related with higher use of pesticides for agricultural applications. The observed higher concentrations of 4,4'-DDE and 4,4'-DDT in the mothers from rural+semi-urban sites than in urban areas were consistent with this agricultural origin. In addition, the most volatile organochlorine compounds included in this study, HCB and α-HCH, were mainly found in Ushuaia. The concentrations of the studied organohalogen pollutants in Argentina were lower than those found in other similar studies which is consistent with the location of these cities in the southern hemisphere. Age, mainly for 4,4'-DDE and polychlorobiphenyl (PCB) congeners 138, 153 and 180, and parity, mainly for HCB, ß-HCH, 4,4'-DDT and PCB congener 118, were the second main determinants of the concentrations of these compounds. Gestational weight gain also influenced on the maternal levels of HCB, ß-HCH, 4,4'-DDT and PCB congeners 118, 138 and 153. Higher weight accumulation during pregnancy involved dilution of these persistent pollutants. Body mass index (BMI) was a statistically significant determinant for 4,4'-DDT, α-HCH and PCB congeners 153 and 180. The observed direct correspondence between higher BMI and 4,4'-DDT concentrations was in agreement with the above reported inputs related with agricultural applications. The reverse correspondence of BMI with α-HCH and the PCB congeners indicated higher dilution at higher weight increase.

Congenital anomalies of the kidney and the urinary tract: A murmansk county birth registry study.

BACKGROUND: Congenital anomalies of the kidney and the urinary tract (CAKUTs) are relatively common birth defects. The combined prevalence in Europe was 3.3 per 1000 in 2012. The risk factors for these anomalies are not clearly identified. The aims of our study were to calculate the birth prevalences of urinary malformations in Murmansk County during 2006 to 2011 and to investigate related prenatal risk factors. METHODS: The Murmansk County Birth Registry was the primary source of information and our study included 50,936 singletons in the examination of structure, prevalence and proportional distribution of CAKUTs. The multivariate analyses of risk factors involved 39,322 newborns. RESULTS: The prevalence of CAKUTs was 4.0 per 1000 newborns (95% confidence interval [CI], 3.4-4.5) and did not change during the study period. The most prevalent malformation was congenital hydronephrosis (14.2% of all cases). Diabetes mellitus or gestational diabetes (odds ratio [OR] = 4.77; 95% CI, 1.16-19.65), acute infections while pregnant (OR = 1.83; 95% CI, 1.14-2.94), the use of medication during pregnancy (OR = 2.03; 95% CI, 1.44-2.82), and conception during the summer (OR = 1.75; 95% CI 1.15-2.66) were significantly associated with higher risk of CAKUTs. CONCLUSION: The overall fourfold enhancement of the occurrence of urinary malformations in Murmansk County for the 2006 to 2011 period showed little annual dependence. During pregnancy, use of medications, infections, pre-existing diabetes mellitus, or gestational diabetes were associated with increased risk of these anomalies, as was conception during summer. Our findings have direct applications in improving prenatal care in Murmansk County and establishing targets for prenatal screening and women's consultations.

Maternal Risk Factors for Preterm Birth in Murmansk County, Russia: A Registry-Based Study.

BACKGROUND: Globally, about 11% of all liveborn infants are preterm. To date, data on prevalence and risk factors of preterm birth (PTB) in Russia are limited. The aims of this study were to estimate the prevalence of PTB in Murmansk County, Northwestern Russia and to investigate associations between PTB and selected maternal factors using the Murmansk County Birth Registry. METHODS: We conducted a registry-based study of 52 806 births (2006-2011). In total, 51 156 births were included in the prevalence analysis, of which 3546 were PTBs. Odds ratios with 95% confidence intervals of moderate-to-late PTB, very PTB and extremely PTB for a range of maternal characteristics were estimated using multinomial logistic regression, adjusting for potential confounders. RESULTS: The overall prevalence of PTB in Murmansk County was 6.9%. Unmarried status, prior PTBs, spontaneous and induced abortions were strongly associated with PTB at any gestational age. Maternal low educational level increased the risk of extremely and moderate-to-late PTB. Young (<18 years) or older (≥35 years) mothers, graduates of vocational schools, underweight, overweight/obese mothers, and smokers were at higher risk of moderate-to-late PTB. Secondary education, alcohol abuse, diabetes mellitus, or gestational diabetes were strongly associated with moderate-to-late and very PTB. CONCLUSIONS: The observed prevalence of PTB (6.9%) in Murmansk County, Russia was comparable with data on live PTB from European countries. Adverse prior pregnancy outcomes, maternal low educational level, unmarried status, alcohol abuse, and diabetes mellitus or gestational diabetes were the most common risk factors for PTB.

Prevalence of smoking before and during pregnancy and changes in this habit during pregnancy in Northwest Russia: a Murmansk county birth registry study.

BACKGROUND: Smoking during pregnancy leads to adverse maternal and birth outcomes. However, the prevalence of smoking among women in Russia has increased from < 5% in the 1980s to > 20% in the 2000s. We conducted a registry-based study in Murmansk County, Northwest Russia. Our aims were twofold: (i) assess the prevalence of smoking before and during pregnancy; and (ii) examine the socio-demographic factors associated with giving up smoking or reducing the number of cigarettes smoked once pregnancy was established. METHODS: This study employs data from the population-based Murmansk County Birth Registry (MCBR) collected during 2006-2011. We used logistic regression to investigate associations between women's socio-demographic characteristics and changes in smoking habit during pregnancy. To avoid departure from uniform risk within specific delivery departments, we employed clustered robust standard errors. RESULTS: Of all births registered in the MCBR, 25.2% of the mothers were smokers before pregnancy and 18.9% continued smoking during pregnancy. Cessation of smoking during pregnancy was associated with education, marital status and parity but not with maternal age, place of residence, and ethnicity. Women aged ≤ 20-24 years had higher odds of reducing the absolute numbers of cigarettes smoked per day during pregnancy than those aged ≥ 30-34 years. Moreover, smoking nulliparae and pregnant women who had one child were more likely to reduce the absolute numbers of cigarettes smoked per day compared to women having ≥ 2 children. CONCLUSIONS: About 25.0% of smoking women in the Murmansk County in Northwest Russia quit smoking after awareness of the pregnancy, and one-third of them reduced the number cigarettes smoked during pregnancy. Our study demonstrates that women who have a higher education, husband, and are primiparous are more likely to quit smoking during pregnancy. Maternal age and number of children are indicators that influence reduction in smoking during pregnancy. Our findings are useful in identifying target groups for smoking intervention campaigns.

Electron microscopy of particles deposited in the lungs of nickel refinery workers.

The size, morphology, and chemical composition of particles deposited in the lungs of two nickel refinery workers were studied by scanning and transmission electron microscopy. The particles were extracted from the lung tissue by low-temperature ashing or by dissolution in tetramethylammonium hydroxide. The suitability of both sample preparation techniques was checked with reference materials. Both approaches lead to Fe-rich artifact particles. Low-temperature ashing leads to oxidation of small (diameter < 2 µm) metallic Ni and Ni sulfide particles, dissolution in tetramethylammonium hydroxide to removal of sulfate surface layers. Silicates and alumosilicates are the most abundant particle groups in the lungs of both subjects. From the various metal-dominated particle groups, Ni-rich particles are most abundant followed by Fe-rich and Ti-rich particles. Ni appears to be present predominantly as an oxide. Pure Ni metal and Ni sulfides were not observed. The presence of soluble Ni phases was not investigated as they will not be preserved during sample preparation. Based on their spherical morphology, it is estimated that a large fraction of Ni-rich particles (50-60 % by number) as well as Fe-rich and Cu-rich particles (27-45 %) originate from high-temperature processes (smelting, welding). This fraction is much lower for silicates (3-5 %), alumosilicates (1-2 %), and Ti-rich particles (9-11 %). The absence of metallic Ni particles most likely results from low exposure to this species. The absence of Ni sulfides may be either ascribed to low exposure or to fast clearance.

Changes in detection of birth defects and perinatal mortality after introduction of prenatal ultrasound screening in the Kola Peninsula (North-West Russia): combination of two birth registries.

BACKGROUND: Prenatal diagnostics ultrasound was established in Russia in 2000 as a routine method of screening for birth defects. The aims of the current study were twofold: to assess changes in birth defects prevalence at birth and perinatal mortality after ultrasound screening was implemented and to estimate prenatal detection rates for congenital malformations in the city of Monchegorsk (Murmansk County, North-West Russia). METHODS: The Murmansk County Birth Registry and the Kola Birth Registry were the primary sources of information, and include 30 448 pregnancy outcomes in Monchegorsk for the period 1973-2011. Data from these registries were supplemented with information derived from hospital records about pregnancy terminations for 2000-2007. RESULTS: The total number of newborns with any kind of birth defects in Monchegorsk during 1973-2011 was 1099, of whom 816 were born in the 1973-2000 period. The prevalence of defects at birth increased from 34.2/1000 (95% CI = 31.9-36.5) to 42.8/1000 newborns (95% CI = 38.0-47.7) after prenatal ultrasound screening was formally implemented. We observed significant decreases (p < 0.05) in the birth prevalence of congenital malformations of the circulatory system, the musculoskeletal system (including deformations), and other (excluding multiple); those of the urinary system increased from 0.9/1000 to 17.1/1000 (p < 0.0001). The perinatal mortality among newborns with any kind of malformation decreased from 106.6 per 1000 newborns with birth defects (95% CI = 84.3-129.1) to 21.2 (95 % CI = 4.3-38.1). Mothers who had undergone at least one ultrasound examination during pregnancy (n = 9883) had a decreased risk of having a newborn die during the perinatal period [adjusted OR = 0.49 (95% CI = 0.27-0.89)]. The overall prenatal detection rate was 34.9% with the highest for malformations of the nervous system. CONCLUSION: Improved detection of severe malformations with subsequent pregnancy termination was likely the main contributor to the observed decrease in perinatal mortality in Murmansk County, Russia.

Prevalence of birth defects in an Arctic Russian setting from 1973 to 2011: a register-based study.

BACKGROUND: Birth defects (BD) constitute an important public health issue as they are the main cause of infant death. Their prevalence in Europe for 2008-2012 was 25.6 per 1000 newborns. To date, there are no population-based studies for the Russian Federation. The aim of the present study is to estimate the prevalence of BD, its forms, and changes over time in the Russian Arctic city of Monchegorsk (Murmansk County) for the period 1973-2011. METHODS: The Murmansk County Birth Register and the Kola Birth Register were the primary sources of information, covering 30448 pregnancy outcomes in Monchegorsk (Murmansk County, Russia) during the study period. RESULTS: The total perinatal prevalence of BD was 36.1/1000 live births (LB) and stillborn (SB) (95% CI = 34.0-38.2). After exclusions of minor malformations according to the European Surveillance of Congenital Anomalies guidelines, it decreased to 26.5/1000 LB plus SB (95% CI = 24.6-28.3). The perinatal prevalence of BD that are obligatory to report in Russia was 7.3/1000 LB plus SB (95% CI = 6.4-8.3). There was a significant positive time-trend in total perinatal prevalence of birth defects across the study period (p < 0.001 for trend). Prevalence of all BD increased from 23.5/1000 to 46.3/1000 (LB plus SB), while that excluding minor defects rose from 17.7/1000 to 35.7/1000 (LB plus SB). The most prevalent group of defects was malformations of the musculoskeletal system, which represented 35.4% of all BD. The most prominent increase was observed for the urinary system, rising from 0.2/1000 to 19.1/1000 (LB plus SB). CONCLUSIONS: The observed perinatal prevalence of BD in Monchegorsk increased two-fold during the 38-year study period. Further investigations to identify the underlying bases for the observed progressive growth in BD are recommended.

Profile of per- and polyfluoroalkyl substances, source appointment, and determinants in Argentinean postpartum women.

BACKGROUND: Per- and polyfluoroalkyl substances (PFAS) are a group of synthetic chemicals with potential adverse health effects. Information concerning PFAS concentrations in relation to pregnancy is scarce in South America and non-existent in Argentina. AIM: We aimed to investigate an extended maternal PFAS profile herein serum concentrations in a regional and global view, source appointment, and determinants in Argentinean women. METHODS: A cross-sectional study with a sampling period from 2011 to 2012 included 689 women from Ushuaia and Salta in Argentina. Serum samples collected two days postpartum were analyzed by ultra-high pressure liquid chromatography coupled to electrospray negative ionisation tandem-quadrupole mass-spectrometry. Principal Component Analysis (PCA) following absolute principal component score-multiple linear regression (APCS-MLR) was used for PFAS source appointments. Determinants of PFAS were explored through a MLR approach. A review of previous studies within the same period was conducted to compare with present levels. RESULTS: Argentinean PFAS concentrations were the lowest worldwide, with PFOS (0.74 ng/mL) and PFOA (0.11 ng/mL) as the dominant substances. Detection frequencies largely aligned with the compared studies, indicating the worldwide PFAS distribution considering the restrictions. The PCA revealed region-specific loading patterns of two component groups of PFAS, a mixture of replaced and legacy substances in Ushuaia and long-chain in Salta. This might relate to a mix of non-diet and diet exposure in Ushuaia and diet in Salta. Region, age, lactation, parity, household members, migration, bottled water, and freshwater fish were among the determinants of various PFAS. CONCLUSION: This is the first study to monitor human PFAS exposure in Argentina. Maternal PFAS concentrations were the lowest observed worldwide in the same period. Exposure contributions are suggested to be affected by restrictions and substitutions. Given the limited population-based studies and the emergence of PFAS, it is essential to conduct further monitoring of PFAS in Argentina and South America.

Awareness of postpartum depression among midwives and pregnant women in Arkhangelsk, Arctic Russia.

BACKGROUND: Postpartum depression (PPD) affects approximately 17% of the women worldwide with nearly half of all cases going undetected. More research on maternal mental health, particularly among healthcare professionals and pregnant mothers, could help identify PPD risks and reduce its prevalence. OBJECTIVE: Given that awareness of PPD is a crucial preventive factor, we studied PPD awareness among midwives and pregnant women in Arkhangelsk, Arctic Russia. METHODS: A qualitative study was conducted using in-depth semi-structured interviews. Midwives and pregnant women were recruited from the women's clinic of the Arkhangelsk municipal polyclinic. Seven midwives and 12 pregnant mothers were interviewed. RESULTS: Midwives described limited time for psychological counselling of pregnant women; they reported that their primary focus was on the physiological well-being of women. Pregnant women have expressed a desire for their families to share responsibilities. The participants considered PPD as a mix of psychological and physiological symptoms, and they also highlighted a discrepancy between the expectations of pregnant women and the reality of motherhood. The present study underscored the limited understanding of PPD identification. CONCLUSIONS: The findings suggest that there is a need for increased awareness among midwives and pregnant women regarding PPD. Prevention programs targeting PPD with a specific emphasis on enhancing maternal mental health knowledge are warranted.

Main findings: Pregnant women and midwives in an Arctic Russian setting have low awareness of postpartum depression.Added knowledge: Improved awareness among pregnant women and midwives about the mental health of women after childbirth, educating pregnant women about symptoms of postpartum depression, encourage them to express their needs and collaboration with family supporters may help to reduce postpartum depression burden.Global health impact for policy and action: Updated campaigns and prevention programs with the focus on increasing the knowledge on mental health among pregnant women and health personnel may be effective support for Primary health care.

Women's experience of preterm birth in an East African context: a qualitative study.

Background: Approximately 15 million children are born each year prematurely, representing more than 10 percent of all childbirths worldwide. Prematurity is an acute event and the leading cause of death among newborns and children under five. Sixty percent of these premature deaths occur in Sub-Saharan Africa and Southeast Asia. Objective: The current study aimed to explore and understand women's experiences and perceptions regarding giving birth prematurely at the National Hospital of Muhimbili in Dar es Salaam, Tanzania. Method: A qualitative method, using Interpretive Phenomenological Analysis approach was chosen to understand and describe the women's experiences. A semi-structured guide was used during the interviews. All interviews were audio-recorded and transcribed verbatim. Findings: Eight in-depth interviews were conducted. The analysis revealed three superordinate themes: (a) Emotional turmoil: unmet expectations shattering maternal identity, emotional distress, and loss of hope; (b) Adapting to preterm birth and challenges: the unexpected situation, lack of proper care, strenuous breastfeeding routines, and socioeconomic challenges; (c) Significance of proper care and emotional support: good maternal care, mother-to-mother and family support. Conclusion: This study provided a deeper understanding of women's experiences and perceptions of premature childbirth. The current study indicated the importance of caregivers' awareness of the women's emotional distress, their need to adapt to a sudden unexpected situation, and the necessity of emotional support.

Why some women fail to give birth at health facilities: a qualitative study of women's perceptions of perinatal care from rural Southern Malawi.

BACKGROUND: Despite Malawi government's policy to support women to deliver in health facilities with the assistance of skilled attendants, some women do not access this care. OBJECTIVE: The study explores the reasons why women delivered at home without skilled attendance despite receiving antenatal care at a health centre and their perceptions of perinatal care. METHODS: A descriptive study design with qualitative data collection and analysis methods. Data were collected through face-to-face in-depth interviews using a semi- structured interview guide that collected information on women's perception on perinatal care. A total of 12 in- depth interviews were conducted with women that had delivered at home in the period December 2010 to March 2011. The women were asked how they perceived the care they received from health workers before, during, and after delivery. Data were manually analyzed using thematic analysis. RESULTS: Onset of labor at night, rainy season, rapid labor, socio-cultural factors and health workers' attitudes were related to the women delivering at home. The participants were assisted in the delivery by traditional birth attendants, relatives or neighbors. Two women delivered alone. Most women went to the health facility the same day after delivery. CONCLUSIONS: This study reveals beliefs about labor and delivery that need to be addressed through provision of appropriate perinatal information to raise community awareness. Even though, it is not easy to change cultural beliefs to convince women to use health facilities for deliveries. There is a need for further exploration of barriers that prevent women from accessing health care for better understanding and subsequently identification of optimal solutions with involvement of the communities themselves.

A call for urgent monitoring of food and water security based on relevant indicators for the Arctic.

This perspective paper argues for an urgent need to monitor a set of 12 concrete, measurable indicators of food and water security in the Arctic over time. Such a quantitative indicator approach may be viewed as representing a reductionist rather than a holistic perspective, but is nevertheless necessary for actually knowing what reality aspects to monitor in order to accurately understand, quantify, and be able to project critical changes to food and water security of both indigenous and non-indigenous people in the Arctic. More relevant indicators may be developed in the future, taking us further toward reconciliation between reductionist and holistic approaches to change assessment and understanding. However, the potential of such further development to improved holistic change assessment is not an argument not to urgently start to monitor and quantify the changes in food and water security indicators that are immediately available and adequate for the Arctic context.

Secular trends of socio-demographic and lifestyle characteristics among delivering women in Arctic Russia, 1973-2017.

The aim of this study was to describe temporal trends in socio-demographic and lifestyle characteristics among delivering women in two Northern provinces of Russia from 1973 to 2017. Totally 161,730 births were registered in three birth registries. Changes in the distribution of maternal age, education, marital status, smoking during pregnancy were studied using Pearson's chi-squared tests and one-way ANOVA. The logistic regression models were used to assess factors, contributing to the variations in the prevalence of maternal smoking. The mean age of primiparous mothers increased from 22.1 years in 1973-1980 to 25.4 years in 2012-2017 (p < 0.001). The proportion of primiparous mothers with higher education increased from 26.2% in 2006 to 38.3% in 2017 (p < 0.001). The proportion of cohabiting primiparous women increased from 5.0% to 15.2% over the study period (p < 0.001). The proportion of mothers smoking during pregnancy decreased from 18.9% in 2006-2011 to 14.8% in 2012-2017 (p < 0.001). Downward in the prevalence of smoking was revealed in 2012-2017 compared to 2006-2011 (OR = 137.76; 95%CI:71.62-264.96, OR = 183.74; 95%CI:95.52-353.41, respectively). Over the past decades, women postpone childbearing until receiving higher education, continue living in cohabitation during pregnancy and smoke less.

Serum Concentrations of Selected Poly- and Perfluoroalkyl Substances (PFASs) in Pregnant Women and Associations with Birth Outcomes. A Cross-Sectional Study from Southern Malawi.

Pervasive exposure to per-and polyfluoroalkyl substances (PFASs) shows associations with adverse pregnancy outcomes. The aim of the present study was to examine the determinants of different serum PFAS concentrations in late pregnancy and their relationship with birth outcomes in southern Malawi. The sample included 605 pregnant women with a mean age of 24.8 years and their offspring from three districts in the southern region of Malawi. Six PFAS were measured in serum from third-trimester women. The serum PFAS concentrations were assessed with head circumference, birth length, birth weight, gestational age and ponderal index. Participants living in urban areas had significantly higher serum levels of PFOA, PFNA and SumPFOS, while SumPFHxS concentrations were higher in women from rural settings. High PFOA, PFNA and SumPFHxS concentrations were generally inversely associated with head circumference. Birth length was negatively associated with PFOA and PFNA while SumPFHxS was negatively associated with birth weight. SumPFOS was inversely associated with gestational age. Urban area of residence was the strongest predictor for high PFAS concentrations in the maternal serum and was generally associated with adverse birth outcomes. The results highlight the need to investigate SumPFHxS further as it follows a pattern that is different to similar compounds and cohorts.
