- BACKGROUND: Recent identification of 10 germline variants predisposing to monoclonal gammopathy of undetermined significance (MGUS) explicates genetic dependency of this asymptomatic precursor condition with multiple myeloma (MM). Yet much of genetic burden as well as functional links remain unexplained. We propose a workflow to expand the search for susceptibility loci with genome-wide interaction and for subsequent identification of genetic clusters and pathways.METHODS: Polygenic interaction analysis on 243 cases/1285 controls identified 14 paired risk loci belonging to unique chromosomal bands which were then replicated in two independent sets (case only study, 82 individuals; case/control study 236 cases/ 2484 controls). Further investigation on gene-set enrichment, regulatory pathway and genetic network was carried out with stand-alone in silico tools separately for both interaction and genome-wide association study-detected risk loci.RESULTS: Intronic-PREX1 (20q13.13), a reported locus predisposing to MM was confirmed to have contribution to excess MGUS risk in interaction with SETBP1, a well-established candidate predisposing to myeloid malignancies. Pathway enrichment showed B cell receptor signaling pathway (P < 5.3 × 10- 3) downstream to allograft rejection pathway (P < 5.6 × 10- 4) and autoimmune thyroid disease pathway (P < 9.3 × 10- 4) as well as epidermal growth factor receptor regulation pathway (P < 2.4 × 10- 2) to be differentially regulated. Oncogene ALK and CDH2 were also identified to be moderately interacting with rs10251201 and rs16966921, two previously reported risk loci for MGUS.CONCLUSIONS: We described novel pathways and variants potentially causal for MGUS. The methodology thus proposed to facilitate our search streamlines risk locus-based interaction, genetic network and pathway enrichment analyses.

- Exclusive breastfeeding is the optimal infant nutrition, providing infants immunoprotection against many diseases including SARS-CoV-2 infection. Restrictions during the COVID-19 pandemic may have negatively affected breastfeeding practices inmaternity care facilities. The aims of the study were to examine exclusive breastfeeding rates at discharge over time and to identify factors associated with exclusive breastfeeding during the pandemic.A cross-sectional survey was conducted among mothers who gave birth in a maternity care facility in the World Health Organization (WHO) European Region countries during the COVID-19 pandemic. The socio-ecological model was employed to examine intrapersonal, interpersonal, organizational, and community/society factors associated with maternal report of exclusive breastfeeding at the time of discharge.There were 26,709 participating mothers from 17 European Region countries who were included in the analysis. Among the mothers, 72.4% (n=19,350) exclusively breastfed and 27.6% (n=7,359) did not exclusively breastfeed at discharge. There was an overall decline in exclusive breastfeeding rates over time (p=0.015) with a significantly lower rate following the publication of the WHO breastfeeding guidelines on 23 June 2020 (AOR 0.88; 95% CI 0.82, 0.94). Factors significantly associated with exclusive breastfeeding outcomes in the logistic regression analysis included maternal age, parity, education, health insurance, mode of birth, inadequate breastfeeding support, lack of early breastfeeding initiation, lack of full rooming-in, birth attendant, perceived healthcare professionalism and attention, facility room cleanliness, timing of birth, and location of birth.Results from the study indicate the decline in exclusive breastfeeding rates in the WHO European Region during the COVID-19 pandemic. Using the socio-ecological model to identify factors associated with breastfeeding outcomes facilitates an integrated and holistic approach to address breastfeeding needs among women across the region. These findings demonstrate the need to augment breastfeeding support and to protect exclusive breastfeeding among mother-infant dyads, in an effort to reverse the declining exclusive breastfeeding rates. The study highlights the need to educate mothers and their families about the importance of exclusive breastfeeding, reduce maternal-infant separation, increase professional breastfeeding support, and follow evidence-based practice guidelines to promote breastfeeding in a comprehensive and multi-level manner.Clinical Trials NCT04847336.

- Background: Multi-country studies assessing the quality of maternal and newborn care (QMNC) during the COVID-19 pandemic, as defined by WHO Standards, are lacking.Methods: Women who gave birth in 12 countries of the WHO European Region from March 1, 2020 - March 15, 2021 answered an online questionnaire, including 40 WHO Standard-based Quality Measures.Findings: 21,027 mothers were included in the analysis. Among those who experienced labour (N=18,063), 41·8% (26·1%- 63·5%) experienced difficulties in accessing antenatal care, 62% (12·6%-99·0%) were not allowed a companion of choice, 31·1% (16·5%-56·9%) received inadequate breastfeeding support, 34·4% (5·2%-64·8%) reported that health workers were not always using protective personal equipment, and 31·8% (17·8%-53·1%) rated the health workers' number as "insufficient". Episiotomy was performed in 20·1% (6·1%-66·0%) of spontaneous vaginal births and fundal pressure applied in 41·2% (11·5% -100%) of instrumental vaginal births. In addition, 23·9% women felt they were not treated with dignity (12·8%-59·8%), 12·5% (7·0%-23·4%) suffered abuse, and 2·4% (0·1%-26·2%) made informal payments. Most findings were significantly worse among women with prelabour caesarean birth (N=2,964). Multivariate analyses confirmed significant differences among countries, with Croatia, Romania, Serbia showing significant lower QMNC Indexes and Luxemburg showing a significantly higher QMNC Index than the total sample. Younger women and those with operative births also reported significantly lower QMNC Indexes.Interpretation: Mothers reports revealed large inequities in QMNC across countries of the WHO European Region. Quality improvement initiatives to reduce these inequities and promote evidence-based, patient-centred respectful care for all mothers and newborns during the COVID-19 pandemic and beyond are urgently needed.Funding: The study was financially supported by the Institute for Maternal and Child Health IRCCS Burlo Garofolo, Trieste, Italy.Study registration: ClinicalTrials.gov Identifier: NCT04847336.

- To explore the quality of maternal and newborn care (QMNC) during the COVID-19 pandemic by facility type among 16 European countries, comparing rates of instrumental vaginal birth and cesarean.Women who gave birth in the WHO European Region from March 1, 2020, to February 7, 2022, answered a validated online questionnaire. Rates of instrumental birth, instrumental vaginal birth, and cesarean, and a QMNC index were calculated for births in public versus private facilities.Responses from 25 206 participants were analyzed. Women giving birth in private compared with public facilities reported significantly more frequent total cesarean (32.5% vs 19.0%; aOR 1.70; 95% CI 1.52-1.90), elective cesarean (17.3% vs 7.8%; aOR 1.90; 95% CI 1.65-2.19), and emergency cesarean before labor (7.4% vs 3.9%; aOR 1.39; 95% CI 1.14-1.70) (P <0.001 for all comparisons), with analyses by country confirming these results. QMNC index results were heterogeneous across countries and regions in the same country and were largely affected by geographical distribution of regions rather than by type of facility alone.The study confirms that births in private facilities have higher odds of cesarean. It also suggests that QMNC should be closely monitored in all facilities to achieve high-quality care, independent of facility type or geographical distribution.NCT04847336.

- To investigate potential associations between individual and country-level factors and medicalization of birth in 15 European countries during the COVID-19 pandemic.Online anonymous survey of women who gave birth in 2020-2021. Multivariable multilevel logistic regression models estimating associations between indicators of medicalization (cesarean, instrumental vaginal birth [IVB], episiotomy, fundal pressure) and proxy variables related to care culture and contextual factors at the individual and country level.Among 27173 women, 24.4% (n=6650) had a cesarean and 8.8% (n=2380) an IVB. Among women with IVB, 41.9% (n=998) reported receiving fundal pressure. Among women with spontaneous vaginal births, 22.3% (n=4048) had an episiotomy. Less respectful care, as perceived by the women, was associated with higher levels of medicalization. For example, women who reported having a cesarean, IVB, or episiotomy reported not feeling treated with dignity more frequently than women who did not have those interventions (odds ratio [OR] 1.37; OR 1.61; OR 1.51, respectively; all: P<0.001). Country-level variables contributed to explaining some of the variance between countries.We recommend a greater emphasis in health policies on promotion of respectful and patient-centered care approaches to birth to enhance women's experiences of care, and the development of a European-level indicator to monitor medicalization of reproductive care.

- Objective: To investigate women's perspectives on the quality of maternal and newborn care (QMNC) around the time of childbirth during the COVID-19 pandemic in Latvia, comparing the years 2020 and 2021, among women who went into labor or had a prelabor cesarean. Methods: Women giving birth in healthcare facilities in Latvia from March 1, 2020, to October 28, 2021, answered an online questionnaire including 40 WHO standards-based quality measures. Descriptive and multivariate quantile regression analyses were performed to compare QMNC in 2020 and 2021. Results: 2079 women were included in the analysis: 1860 women who went into labor (group 1) and 219 with prelabor cesarean (group 2). Among group 1, 66.4% (n = 99/149) of women received fundal pressure in an instrumental vaginal birth, 43.5% (n = 810) lacked involvement in choices, 17.4% (n = 317) reported suffering abuse, 32.7% (n = 609) reported inadequate breastfeeding support while 5.2% (n = 96) lack of early breastfeeding. A significant reduction in QMNC due to the COVID-19 pandemic was reported by 29.5% (n = 219) and 25.0% (n = 270) of respondents in 2020 and 2021, respectively (P = 0.045). Multivariate analyses highlighted a significantly lower QMNC index for 2020 compared with 2021 (P < 0.001). Conclusion: This first study investigating QMNC in Latvia showed significant gaps in QMNC perceived by respondents, with slightly better results in 2021. Appropriate healthcare strategies to improve health care for women and newborns in Latvia are required. ClinicalTrials.gov Identifier:NCT04847336.
