Abstract
Objective: to evaluate the effect of prenatal care (PC) on perinatal outcomes of pregnant women with diabetes mellitus (DM). Methods: systematic review developed according to Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) 2020 guidelines and conducted through the population, intervention, control, and outcomes (PICO) strategy. Clinical trials and observational studies were selected, with adult pregnant women, single-fetus pregnancy, diagnosis of DM, or gestational DM and who had received PC and/or nutritional therapy (NT). The search was carried out in PubMed, Scopus, and BIREME databases. The quality of the studies was evaluated using the tools of the National Heart, Lung and Blood Institute-National Institutes of Health (NHLBI-NIH). Results: We identified 5972 records, of which 15 (n=47 420 pregnant women) met the eligibility criteria. The most recurrent outcomes were glycemic control (14 studies; n=9096 participants), hypertensive disorders of pregnancy (2; n=39 282), prematurity (6; n=40 163), large for gestational age newborns (4; n=1556), fetal macrosomia (birth weight >4kg) (6; n=2980) and intensive care unit admission (4; n=2022). Conclusions: The findings suggest that PC interferes with the perinatal outcome, being able to reduce the risks of complications associated with this comorbidity through early intervention, especially when the NT is an integral part of this assistance.

Abstract
PURPOSE/OBJECTIVE(S) This study aimed to investigate the travel distance for cancer patients treated with radiotherapy in Victoria, Australia, during a 9-year period relative to their home address. Additionally, the study aimed to quantify 'excess' travel distance where patients travelled to treatment centers that were not their closest. MATERIALS/METHODS The PRedicting the health economic IMPact of new and current CAncer Treatments (PRIMCAT) dataset was used for the study. PRIMCAT is a multi-institution research initiative taking a data-driven modelling approach to understand and forecast cancer treatment utilization in Australia. The PRIMCAT dataset is a comprehensive linked dataset including a retrospective cohort of patients 18 years and over, diagnosed with cancer included in the Victorian Cancer Registry between January 2010 to December 2019. For each patient in the cohort, data linkage includes a range of datasets managed by state and federal health departments including the Victorian Radiotherapy Minimum Dataset. A distance matrix was constructed using the Google Distance Matrix API that included driving distance between postcodes of selected patients and the postcodes of radiotherapy facilities. The centroid of each post-code was used for driving distance measurements. We first analyzed the realized travel distances of patients followed by the excess travel by patients. The excess travel was further quantified separately for public and private radiotherapy facilities. RESULTS There were 86,408 unique patient-radiotherapy courses available and of sufficient data quality to analyze. Patients travelled an average of 42.5km (s.d. = 72.2km) one-way, with a median travel distance of 16.5km. The largest distance travelled was 723km with 95% of patients travelling between 0km and 257km. Of the patients who received radiotherapy in a public facility, 44.3% travelled to a facility that was not their closest public facility. The average excess travel of these patients was 26.8km, with the median excess travel being 13.6km. Additionally, of patients who received care in a public facility, 47.4% travelled past a closer private facility. The average excess travel distance of these patients was 23.1km and the median excess travel was 11.5km. In the case of patients who received radiotherapy at a private facility, 92.8% travelled to a clinic that was not their closest. The average excess of these patients was 36.6km with a median excess travel distance of 15.6km. CONCLUSION Access to radiotherapy facilities remains unequal in Victoria with some patients having to travel significantly greater distances than average. This significant travel may require patients to take time off work or live away from home presenting additional financial challenges. The reasons for the large travel distances and any excess travel have not yet been identified but will be the subject of further study.

The prevalence and perinatal repercussions of preeclampsia after the implementation of a prophylaxis protocol with aspirin. Pregnancy Hypertens 2023; 33:17-21. [PMID: 37327650 DOI: 10.1016/j.preghy.2023.06.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2022] [Revised: 06/01/2023] [Accepted: 06/09/2023] [Indexed: 06/18/2023]
Abstract
OBJECTIVES To evaluate the prevalence and perinatal repercussions of preeclampsia (PE) after the implementation of a prophylaxis protocol with aspirin in singleton pregnancy at Maternity School of Federal University of Rio de Janeiro, Rio de Janeiro, Brazil (2015-2106). METHODOLOGY PE prevalence according to gestational age (GA) and the prevalence ratio (PR) between PE and prematurity, small for gestational age (SGA), and fetal death were calculated in patients assisted during 2015 and 2016. RESULTS PE occurred in 373(10.75%) of 3468 investigated cases, where PE < 37 weeks was of 2.79% and PE greater than 37 weeks was of 7.95%. A total of 413 (11.9%) prematurity cases, 320 SGA (9.22%), and 50 fetal deaths (1.44%) occurred. In the PE group, 97 premature newborns (PR 0.90) and 51 SGA (PR 1.16) were born, and two fetal deaths occurred (PR 7.46). Concerning PE < 37 weeks, 27 SGA cases (PR 1.42) and two fetal deaths (PR 2.62) were observed. Regarding PE greater than 37 weeks, 24 SGA (PR 1.09) were born, and no fetal deaths were observed. Our findings were compared to previously published results. CONCLUSIONS PE was significantly associated with SGA newborns, especially premature PE. Prescribing aspirin for PE prophylaxis based only on clinical risk factors in a real-life scenario does not appear to be effective but resulted in a PE screening and prophylaxis protocol review and update at ME/UFRJ.

Abstract
AIMS To identify predictive factors of birth weight (BW) of newborns of women with pregestational diabetes mellitus (DM). METHODS Retrospective observational study with data from pregnant women who started prenatal nutritional monitoring up to 28 weeks, single pregnancy, and BW information. Quantitative variables were analyzed, and mean and standard deviation (SD) measures or medians and interquartile ranges (IQR) were calculated. Predictive factors were identified using multivariate linear regression. RESULTS Eighty-six pregnant women were analyzed, 50% were diagnosed with type 1 DM, 46.5% with type 2 DM, and 3.5% with unclassified DM; 41% were mixed black and white, 35.6% had overweight and 33.3% had pregestational obesity. The mean BW was 3313.93g (SD=696.08). The predictive factors identified were: gestational weight gain (GWG) at the 3rd trimester (ß=60.42; p=0.04), and gestational age at delivery (ß=194.03; p<0.001); adjusted by time of diagnosis of DM (p=0.07) and 1st-trimester glycated hemoglobin (p=0.71). CONCLUSION The best predictors of BW were gestational age at birth and maternal anthropometric gestational characteristics, which are modifiable variables. The results may contribute to a review of the prenatal routines of pregnant women with DM.

Abstract
This study examined consumers' consumption, motivations, and concerns regarding meat and meat alternatives by means of an online survey of 1061 New Zealand consumers and review of literature. Outcomes of the survey indicate New Zealanders are overwhelmingly omnivorous (93%), regard taste as the most important factor in their meat purchasing decision followed by price and freshness and consider environmental impact and social responsibility of less importance. Those surveyed indicated willingness to pay 17-24% more for food safety and sustainability related meat attributes. About half of respondents lowered their meat consumption the previous year, mainly red and processed meats, due to lack of affordability and health concerns. Although those surveyed showed high awareness about meat alternatives, their consumption level of the products was very low and more prevalent for female, younger and more educated individuals. Overall, the outlook for meat consumption and meat industry in New Zealand is positive and is likely to remain so for the foreseeable future.

Abstract
Hypertensive disorders of pregnancy (HDP) are a leading cause of maternal and perinatal morbimortality. Dietetic, phenotypic, and genotypic factors influencing HDP were analyzed during a nutrigenetic trial in Rio de Janeiro, Brazil (2016-2020). Pregnant women with pregestational diabetes mellitus (n = 70) were randomly assigned to a traditional or DASH diet group. Systolic blood pressure (SBP) and diastolic blood pressure (DBP) were measured during prenatal visits and HDP were diagnosed using international criteria. Phenotypic data were obtained from medical records and personal interviews. Genotyping for FTO and ADRB2 polymorphisms used RT-PCR. Linear mixed-effect models and time-to-event analyses were performed. The variables with significant effect on the risk for progression to HDP were: black skin color (adjusted hazard ratio [aHR] 8.63, p = 0.01), preeclampsia in previous pregnancy (aHR 11.66, p < 0.01), SBP ≥ 114 mmHg in the third trimester (aHR 5.56, p 0.04), DBP ≥ 70 mmHg in the first trimester (aHR 70.15, p = 0.03), mean blood pressure > 100 mmHg (aHR 18.42, p = 0.03), and HbA1c ≥ 6.41% in the third trimester (aHR 4.76, p = 0.03). Dietetic and genotypic features had no significant effect on the outcome, although there was limited statistical power to test both.

Abstract
PURPOSE For patients living with metastatic breast cancer (MBC), achieving best possible health-related quality of life, along with maximizing survival, is vital. Yet, we have no systemic way to determine if we achieve these goals. A Core Outcome Set (COS) that allows standardized measurement of outcomes important to patients, but also promotes discussing these outcomes during clinical encounters, is long overdue. METHODS An international expert group (EG) of patient advocates, researchers, medical specialists, nurse specialists, and pharmaceutical industry representatives (n = 17) reviewed a list of relevant outcomes retrieved from the literature. A broader group (n = 141: patients/patient advocates (n = 45), health care professionals/researchers (n = 64), pharmaceutical industry representatives (n = 28), and health authority representatives (n = 4)) participated in a modified Delphi procedure, scoring the relevance of outcomes in two survey rounds. The EG finalized the COS in a consensus meeting. RESULTS The final MBC COS includes 101 variables about: (1) health-related quality of life (HRQoL, n = 26) and adverse events (n = 24); (2) baseline patient characteristics (n = 9); and (3) clinical variables (n = 42). Many outcome that cover aspects of HRQoL relevant to MBC patients are included, e.g. daily functioning (including ability to work), psychosocial/emotional functioning, sexual functioning, and relationship with the medical team. CONCLUSION The COS developed in this study contains important administrative data, clinical records, and clinician-reported measures that captures the impact of cancer. The COS is important for standardization of clinical research and implementation in daily practice and has received accreditation by the International Consortium for Health Outcomes Measurement (ICHOM).

Abstract
Two damage regimes-"brittle" and "ductile"-have been identified in the literature on ceramic grinding, machining, grit blasting, and wear. In the brittle regime, the damage mechanism is essentially crack formation, while in the ductile region, it is quasiplasticity. Onset of the brittle mode poses the greater threat to strength, so it becomes important to understand the mechanics of ductile-brittle thresholds in these materials. Controlled microcontact tests with a sharp indenter are employed to establish such thresholds for a suite of contemporary computer-aided design/computer-aided manufacturing dental ceramics. Plots of flexural strength S versus indentation load P show a steep decline beyond the threshold, consistent with well-established contact mechanics relations. Threshold dimensions occur on a scale of order 1 µm and contact load of order 1 N, values pertinent to practical grit finishing protocols. The ductile side of ceramic shaping is accessed by reducing grit sizes, applied loads, and depths of cut below critical levels. It is advocated that critical conditions for ductile shaping may be most readily quantified on analogous S(P) plots, but with appropriate machining variable (grit size, depths of cut, infeed rate) replacing load P. Working in the ductile region offers the promise of compelling time and cost economies in prosthesis fabrication and preparation.

Abstract
Purpose The aim of this study was to develop priority recommendations for the service level implementation of patient-reported outcomes (PROs) into clinical cancer care. Methods Development of draft guidance statements was informed by a literature review, the Knowledge to Action (KTA) implementation framework, and discussion with PRO experts and cancer survivors. A two-round modified Delphi survey with key stakeholders including cancer survivors, clinical and research experts, and Information Technology specialists was undertaken. Round 1 rated the importance of the statements and round 2 ranked statements in order of priority. Results Round 1 was completed by 70 participants with round 2 completed by 45 participants. Forty-seven statements were rated in round 2. In round 1, the highest agreement items (>90% agreement) included those that focused on the formation of strong stakeholder partnerships, ensuring ongoing communication within these partnerships, and the use of PROs for improvement and guidance in clinical care. Items ranked as the highest priorities in round 2 included assessment of current staff capabilities and service requirements, mapping of workflows and processes to enable collection, and using collected PROs to guide improved health outcomes. Conclusions This stakeholder consultation process has identified key priorities in PRO implementation into clinical cancer care that include clinical relevance, stakeholder engagement, communication, and integration within the existing processes and capabilities. Implication for Cancer Survivors Routine adoption of PRO collection by clinical cancer services requires multiple implementation steps; of highest priority is strong engagement and communication with key stakeholders including cancer survivors. Supplementary Information The online version contains supplementary material available at 10.1007/s11764-021-01135-2.

Abstract
OBJECTIVE Despite little survival benefit and potential for harm, contralateral prophylactic mastectomy (CPM) rates are increasing amongst early-stage breast cancer patients at low contralateral breast cancer risk. We developed a CPM decision aid (DA) and conducted a pilot implementation. METHODS Surgeons and oncologists recruited eligible patients considering CPM. Consenting patients received the DA, completed a questionnaire and participated in a semi-structured interview. Clinicians were interviewed at study close. RESULTS Eleven clinicians and 31 patients participated. Three themes emerged: perceived utility and impact of the DA, disagreement regarding timing of delivery and target population, and implementation strategies. Both women and clinicians found the DA valuable, indicating it confirmed rather than changed preferences. Women (all of whom raised CPM themselves), preferred offering the DA early in treatment discussions whilst clinicians favoured targeting women who enquired about CPM. CONCLUSION A DA about CPM is feasible and acceptable, but questions remain about the role of DAs in these types of decisions where one option has limited medical benefit. PRACTICE IMPLICATIONS Some women have a high need to make an informed choice about CPM. Tools to support this could include a DA with a clear recommendation against CPM and an explanation why.

Abstract
BACKGROUND & AIMS Most Brazilian women fail to gain weight within recommendations during pregnancy but current guidelines about gestational weight gain was based on North American population analysis. There are no standardized recommendations developed from Brazilian population data, which should be particularly analysed due to ethnic and sociodemographic characteristics. This study analyses the gestational weight gain of Brazilian women with favourable obstetric and neonatal outcomes according to the pre-pregnancy body mass index, considering maternal sociodemographic characteristics. METHODS We analysed data from the Birth in Brazil: national survey into labour and birth study, a nationwide hospital-based cohort carried out in 266 Brazilian hospitals from February/2011 to July 2012, including adult pregnant women who have no chronic diseases and who have single foetal gestation, born alive and without malformation. Favourable obstetric and neonatal outcomes considered were gestational age at birth greater than or equal to 37 and less than 42 weeks, birthweight between 2500 g and 4000 g, and birthweight suitable for gestational age. Sociodemographic characteristics were obtained from medical records and interviews. Weight and height information was obtained from the prenatal card or self-reported. The pre-pregnancy BMI was classified in low weight, normal weight, overweight, obesity I, obesity II, and obesity III. For the missing cases on pre-pregnancy weight or height, body mass index was imputed by multiple imputation prediction model. Gestational weight gain was the difference between the last weight before delivery and the pre-pregnancy weight and was presented as mean and confidence interval, mean and standard deviation, and percentiles distribution (10th to 90th) for each pre-pregnancy body mass index, thus compared to Institute of Medicine recommendations. RESULTS The analysis included 8184 Brazilian women. The gestational weight gain was lower in women with less favoured social conditions. The mean gestational weight gain according to pre-pregnancy body mass index was within the Institute of Medicine recommendations, except for women with overweight or obesity class I, who have the mean weight gain higher than upper limit of the Institute of Medicine range. Gestational weight gain decreased with an increase in the categories of body mass index; the mean (±standard deviation) were: 15.41 kg (±5.53), 13.54 kg (±4.97), 12.45 kg (±5.86), 9.38 kg (±6.31), 7.15 kg (±6.43), and 5.04 kg (±7.10), for low weight, normal weight, overweight, and obesity I, II and III, respectively. Women had favourable obstetric and neonatal outcomes gaining less, within or more than the recommendations with higher range of variation amongst obesity classes I, II, and III which do not have specific ranges stated in Institute of Medicine guidelines. CONCLUSION Brazilian women had favourable obstetric and neonatal outcomes gaining less, within or more than the Institute of Medicine recommendations. We highlight the need of population-based high-quality research to investigate the optimal GWG recommendations for this population.

Abstract
BACKGROUND Making trials more patient-centred improves recruitment and retention, patient satisfaction and makes research accessible to a more representative population. We aimed to understand the factors that influence participation and engagement in clinical trials in cystic fibrosis (CF) trials to guide the rational design and delivery of patient-centred trials. METHODS We used a Delphi process, supported by extensive literature review and 3 workshops, to determine which factors stakeholders think exert significant influence in participation and engagement in CF trials. Panellists were recruited from across the UK and the study was administered online. RESULTS We had representation from 19 CF centres; 28 people with CF (pwCF), 26 parents and 30 healthcare professionals (HCPs). Panels were presented with a shortlist of 104 factors and asked which they thought influence participation and engagement in CF trials. After 3 iterations, 43 statements met consensus for pwCF, 48 for the parents and 69 for the HCPs. CONCLUSIONS We identified many targets to make trials more patient-centred. Whilst some require an overhaul of trial delivery, many are relatively easy to implement. We outline a list of 'dos and don'ts' for sponsors and research teams including: focus on good communication; recognise that lack of time is the greatest barrier to trial participation so minimise the frequency and length of visits; help participants fit trials around busy lives; remember trial participation can be a major life-event and support participants accordingly; and don't underestimate the impact of simple strategies e.g. on-site access to Wifi and cups of tea.

[PMID: 33787808 DOI: 10.1590/s1679-49742021000100006] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/06/2020] [Accepted: 09/02/2020] [Indexed: 11/22/2022]
Abstract
OBJECTIVE To analyze association of different methods of gestational weight gain assessment with live births small for gestational age (SGA) and large for gestational age (LGA). METHODS This was a cross-sectional study with adult women, normal prepregnancy BMI, single pregnancy and gestational age at delivery ≥28 weeks, from the "Birth in Brazil" study, between 2011 and 2012. RESULTS Among the 11,000 women participating in the study, prevalence of excessive weight gain was 33.1% according to the Brandão et al. and Institute of Medicine (IOM) methods, and 37.9% according to the Intergrowth method. The chance of being born SGA in the case of insufficient weight gain was OR=1.52 (95%CI 1.06;2.19), OR=1.52 (95%CI 1.05;2.20) and OR=1.56 (95%CI 1.06;2.30) for the Brandão et al., IOM and Intergrowth methods, respectively. Likelihood of excessive weight gain using the same methods was OR=1.53 (95%CI 1.28;1.82), OR=1.57 (95%CI 1.31;1.87) and OR=1.65 (95%CI 1.40;1.96), for LGA respectively. CONCLUSION Compared to the IOM recommendations, the Intergrowth and Brandão et al. methods show themselves to be alternatives for identifying SGA and LGA.

Cost-effectiveness of radioguided occult lesion localization using 125I seeds versus hookwire localization before breast-conserving surgery for non-palpable breast cancer. Br J Surg 2021; 108:843-850. [PMID: 33638646 DOI: 10.1093/bjs/znaa160] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/18/2020] [Revised: 09/03/2020] [Accepted: 12/07/2020] [Indexed: 11/13/2022]
Abstract
BACKGROUND The aim was to determine the cost-effectiveness of radioguided occult lesion localization using 125I-labelled seeds (125I seeds) versus hookwire localization in terms of incremental cost per reoperation avoided for women with non-palpable breast cancer undergoing breast-conserving surgery. METHODS This study was based on a multicentre RCT with eight study sites comprising seven public hospitals and one private hospital. An Australian public health system perspective was taken. The primary effectiveness outcome for this study was reoperations avoided. Cost-effectiveness was expressed as an incremental cost-effectiveness ratio (ICER). One-way and probabilistic sensitivity analyses were used to explore uncertainty. The willingness to pay (additional cost of localization using 125I seeds justified by reoperation cost avoided) was set at the weighted, top-down cost of reoperation. Costs were in 2019 Australian dollars ($1 was equivalent to €0.62). RESULTS The reoperation rate was 13.9 (95 per cent confidence interval 10.7 to 18.0) per cent for the 125I seed group and 18.9 (14.8 to 23.8) per cent for the hookwire localization group. The ICER for 125I seed versus hookwire localization was $4474 per reoperation averted. The results were most sensitive to uncertainty around the probability of reoperation. Accounting for transition probability and cost uncertainty for 125I seed localization, there was a 77 per cent probability that using 125I seeds would be cost-effective, with a willingness to pay of $7693 per reoperation averted. CONCLUSION Radioguided occult lesion localization using 125I seeds is likely to be cost-effective, because the marginal (additional) cost compared with hookwire localization is less than the cost of reoperations avoided.

Abstract
Background Surgical-site complications (SSCs) remain a significant cause of morbidity and mortality, particularly in high-risk patients. The aim of this study was to determine whether prophylactic use of a specific single-use negative-pressure wound therapy (sNPWT) device reduced the incidence of SSCs after closed surgical incisions compared with conventional dressings. Methods A systematic literature review was performed using MEDLINE, Embase and the Cochrane Library to identify articles published from January 2011 to August 2018. RCTs and observational studies comparing PICO™ sNPWT with conventional dressings, with at least 10 patients in each treatment arm, were included. Meta-analyses were performed to determine odds ratios (ORs) or mean differences (MDs), as appropriate. PRISMA guidelines were followed. The primary outcome was surgical-site infection (SSI). Secondary outcomes were other SSCs and hospital efficiencies. Risk of bias was assessed. Results Of 6197 citations screened, 29 studies enrolling 5614 patients were included in the review; all studies included patients with risk factors for SSCs. sNPWT reduced the number of SSIs (OR 0.37, 95 per cent c.i. 0.28 to 0.50; number needed to treat (NNT) 20). sNPWT reduced the odds of wound dehiscence (OR 0.70, 0.53 to 0.92; NNT 26), seroma (OR 0.23, 0.11 to 0.45; NNT 13) and necrosis (OR 0.11, 0.03 to 0.39; NNT 12). Mean length of hospital stay was shorter in patients who underwent sNPWT (MD −1.75, 95 per cent c.i. −2.69 to −0.81). Conclusion Use of the sNPWT device in patients with risk factors reduced the incidence of SSCs and the mean length of hospital stay.

Abstract
The aim of this research was to quantify essential trace elements (iron, copper, zinc and iodine) and establish their speciation in human milk. Both the element and the species are important in new-born nutrition. Colostrum, and transitional and mature milks (25) were collected from 18 mothers of pre-term or full-term infants. Concentrations of the target elements were determined using ICP-MS. For speciation, HPLC coupled to ICP-MS was employed. Total contents of the micronutrients varied in mothers of pre-term (Fe = 0.997, Cu = 0.506, Zn = 4.15 and I = 0.458 mg L-1) and mothers of full-term (Fe = 0.733, Cu = 0.234, Zn = 2.91 and I = 0.255 mg L-1) infants. Fe, Cu and Zn were associated with biomolecules with high molecular mass compounds, such as immunoglobulins, albumin and lactoferrin whilst iodine was only found as iodide.

Abstract
BACKGROUND & AIMS Monitoring gestational weight gain (GWG) is relevant for perinatal outcomes, especially in the context of increasing obesity and overweight in the female population. This study analyses the association between GWG in Brazilian women, according to different body mass index (BMI) categories, and different outcomes, including hypertensive disorders of pregnancy (HDP), gestational diabetes (GD) and caesarean section. METHODS Data on women from all the major regions of Brazil with a single pregnancy of a gestational age of 28 weeks or more and information available for anthropometric evaluation were included in the Birth in Brazil survey. Adequacy of GWG was assessed according to the percentile distribution of GWG of women with favourable neonatal outcomes, with the median of the distribution referred to as 100% adequacy in the GWG evaluation. RESULTS The study consisted of 18,953 women, 58.3% of whom were normal weight and 35.1% were overweight. The adequacy of GWG was better amongst the normal weight women (91.1%) and worse amongst those with class III obesity (46.0% with excessive GWG), with the latter showing the highest occurrence of adverse outcomes. Results of the multivariate logistic regression analysis revealed that weight gain above 200% of the median in the normal weight, overweight and obese women was positively associated with HDP and caesarean section, but not with GD. CONCLUSIONS The proposed ranges of appropriate GWG associated with favourable neonatal outcomes based on the data from the Birth in Brazil survey proved good predictors of HDP and caesarean section amongst the women included in the study.

MSTO1 mutations cause mtDNA depletion, manifesting as muscular dystrophy with cerebellar involvement. Acta Neuropathol 2019; 138:1013-1031. [PMID: 31463572 PMCID: PMC6851037 DOI: 10.1007/s00401-019-02059-z] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/06/2019] [Revised: 07/25/2019] [Accepted: 08/08/2019] [Indexed: 01/12/2023]
Abstract
MSTO1 encodes a cytosolic mitochondrial fusion protein, misato homolog 1 or MSTO1. While the full genotype–phenotype spectrum remains to be explored, pathogenic variants in MSTO1 have recently been reported in a small number of patients presenting with a phenotype of cerebellar ataxia, congenital muscle involvement with histologic findings ranging from myopathic to dystrophic and pigmentary retinopathy. The proposed underlying pathogenic mechanism of MSTO1-related disease is suggestive of impaired mitochondrial fusion secondary to a loss of function of MSTO1. Disorders of mitochondrial fusion and fission have been shown to also lead to mitochondrial DNA (mtDNA) depletion, linking them to the mtDNA depletion syndromes, a clinically and genetically diverse class of mitochondrial diseases characterized by a reduction of cellular mtDNA content. However, the consequences of pathogenic variants in MSTO1 on mtDNA maintenance remain poorly understood. We present extensive phenotypic and genetic data from 12 independent families, including 15 new patients harbouring a broad array of bi-allelic MSTO1 pathogenic variants, and we provide functional characterization from seven MSTO1-related disease patient fibroblasts. Bi-allelic loss-of-function variants in MSTO1 manifest clinically with a remarkably consistent phenotype of childhood-onset muscular dystrophy, corticospinal tract dysfunction and early-onset non-progressive cerebellar atrophy. MSTO1 protein was not detectable in the cultured fibroblasts of all seven patients evaluated, suggesting that pathogenic variants result in a loss of protein expression and/or affect protein stability. Consistent with impaired mitochondrial fusion, mitochondrial networks in fibroblasts were found to be fragmented. Furthermore, all fibroblasts were found to have depletion of mtDNA ranging from 30 to 70% along with alterations to mtDNA nucleoids. Our data corroborate the role of MSTO1 as a mitochondrial fusion protein and highlight a previously unrecognized link to mtDNA regulation. As impaired mitochondrial fusion is a recognized cause of mtDNA depletion syndromes, this novel link to mtDNA depletion in patient fibroblasts suggests that MSTO1-deficiency should also be considered a mtDNA depletion syndrome. Thus, we provide mechanistic insight into the disease pathogenesis associated with MSTO1 mutations and further define the clinical spectrum and the natural history of MSTO1-related disease.

Abstract
Abstract
A multilaboratory study was conducted to compare the automated BAX® System to the standard cultural methods for detection of Salmonella in selected foods. Five food types—frankfurters, raw ground beef, mozzarella cheese, raw frozen tilapia fish, and orange juice—at 3 inoculation levels, were analyzed by each method. A sixth food type, raw ground chicken, was tested using 3 naturally contaminated lots. A total of 16 laboratories representing government and industry participated. In this study, 1386 samples were analyzed, of which 1188 were paired samples and 198 were unpaired samples. Of the 1188 paired samples, 461 were positive by both methods and 404 were negative by both methods. Thirty-seven samples were positive by the BAX System but negative by the standard reference method, and 11 samples were positive by standard cultural method and negative by the BAX System. Of the 198 unpaired samples, 106 were positive by the BAX System and 60 were positive by the standard cultural method. A Chi square analysis of each of the 6 food types, at the 3 inoculation levels tested, was performed. For all foods, the BAX System demonstrated results comparable to those of the standard reference methods based on the Chi square results.

Abstract
INTRODUCTION Postpartum weight retention has been found to predict obesity. However, in Brazil, there's no national strategy for nutritional care of postpartum woman. OBJECTIVE This study aimed to adapt DASH diet (Dietary Approaches to Stop Hypertension) for nutritional counseling of postpartum woman, at primary healthcare. METHOD Methodological study, carried out in 2016, at low-income urban neighborhood in the city of Rio de Janeiro. It was developed in four steps: translation, food and food groups adaptation, identification of geographic and economic access to food and viability evaluation. RESULTS The food groups of original diet were structured to Brazilian dietary pattern. After viability analysis, it was observed that the geographical access of food should be accounted to enable greater adherence. A qualitative and illustrated meal plan was elaborated for nutritional counseling. CONCLUSION The adapted DASH diet for nutritional care of postpartum woman seems to be according to the Brazilian dietary pattern, maintaining nutritional characteristics that provide the health benefits previously demonstrated. Currently, it's being used in interventional study in two primary healthcare unities at the city of Rio de Janeiro.

Abstract
This study aimed to identify the determinants of low birth weight (LBW) amongst children of adolescent mothers through a hierarchical approach in a cross-sectional study of 751 adolescents attended at a public hospital in Rio de Janeiro. Sociodemographic data, prenatal care, and biological and maternal obstetric conditions were analyzed. Possible determinants of LBW were identified in the bivariate analysis and then hierarchical logistic regression models were tested, considering as taggered hierarchy of distal, intermediate, and proximal levels. Variables with p < 0.05 at each level of analysis were kept in the model, and the adjusted odds ratio (OR) and 95% confidence interval (CI) were estimated. The prevalence of low birth weight was 10%. The determinants of LBW were: distal level - non-acceptance of pregnancy (OR = 10.19, 95% CI = 1.09 to 39.53); intermediate level - having fewer than six prenatal consultations (OR = 4.29; 95% CI = 1.55 to 11.83) and not having standardized nutritional care (OR = 3.18; 95% CI = 1.18 to 8.55); and proximal level - preterm delivery (OR = 10.19, 95% CI = 2.12 to 49.01). The determinants of LBW were maternal characteristics, prenatal care, and birth conditions, which contain certain modifiable social characteristics.

Abstract
Background: Patient-reported outcome measures (PROMs) are essential for identifying how patients perceive the outcomes of their cancer treatment, and is the ultimate success of cancer care. Although a growing number of studies have focused on PROMs in high income countries (HICs), outcomes relevant to patients in developing countries are less understood. Furthermore, the lack of standardization in PROMs makes it difficult to interpret these data for research or quality monitoring. Aim: In this study, we compared the results of PROM measures between patients in Malaysia, a middle income country, and those in HICs, using standard PROMs questionnaires. We also explored the differences in perceived importance of patient reported outcomes within the multiracial Malaysian cohort. Methods: Breast cancer patients (n=1063) were recruited in hospitals serving suburban areas of Malaysia. Of these, 969 patients were eligible for analysis. The surveys were conducted through face-to-face interviews (68%) or were self-administered (30%). An outcome was considered important if it was scored between 7-9 on a 9-point Likert scale. We compared PROMs scores between Malaysian patients and data previously collected from patients in HICs using logistic regression models, adjusting for demographic and clinical characteristics. A two-step cluster analysis was conducted to explore differences in the perceived importance of PROMs between clusters of Malaysian patients. Results: Compared with 1777 patients from HICs, Malaysian patients were less likely to rate overall and recurrence free survival, as well as emotional, cognitive, social and sexual functioning as very important outcomes. Interestingly, more Malaysian women reported that pain (50% vs. 39%), breast symptoms (51% vs. 35%), and major complications (60% vs. 44%) were very important outcomes ( P < 0.001). Compared with young, married Malaysian women, the cluster of older married women (mean age of 57 vs. 52), who were less likely to have received breast reconstructive surgery (8.6% vs. 16.8%), was more likely to rate sexual functioning (32.8% vs. 25.0%, P = 0.036), body image (63.9% vs. 42.4%, P < 0.001), and satisfaction with the breast (50.7% vs. 37.0%, P = 0.011) as very important outcomes. Conclusion: The differences in breast cancer patient needs between and within populations should be considered carefully to better clinician-patient relationship, patient care and satisfaction and assess the outcomes of our cancer care. Future research is needed to find suitable targeted interventions to identify and address the diverse needs of breast cancer patients in low and middle income countries.

Abstract
BACKGROUND Carcinoma of unknown primary (CUP) is a metastatic epithelial malignancy in the absence of an identifiable primary tumour. Prognosis for patients with CUP is poor because treatment options are generally limited to broad spectrum chemotherapy. A shift towards personalised cancer management based on mutation profiling offers the possibility of new treatment paradigms. This study has explored whether actionable, oncogenic driver mutations are present in CUP that have potential to better inform treatment decisions. METHODS Carcinoma of unknown primary cases (n = 21) were selected and DNA was isolated from formalin-fixed paraffin embedded sections prior to amplification and sequencing. Two distinct yet complementary targeted gene panels were used to assess variants in up to 76 known cancer-related genes for the identification of biologically relevant and actionable mutations. RESULTS Variants were detected in 17/21 cases (81%) of which 11 (52%) were potentially actionable with drugs currently approved for use in known primary cancer types or undergoing clinical trials. The most common variants detected were in TP53 (47%), KRAS (12%), MET (12%) and MYC (12%). Differences at the molecular level were seen between common CUP histological subtypes. CUP adenocarcinomas and poorly differentiated carcinomas harboured the highest frequency of variants in genes involved in signal transduction pathways (e.g. MET, EGFR, HRAS, KRAS, and BRAF). In contrast, squamous cell carcinoma exhibited a higher frequency of variants in cell cycle control and DNA repair genes (e.g. TP53, CDKN2A and MLH1). CONCLUSION Taken together, mutations in biologically relevant genes were detected in the vast majority of CUP tumours, of which half provided a potentially novel treatment option not generally considered in CUP.

Abstract
Background The clinical effectiveness of treating ipsilateral multifocal (MF) and multicentric (MC) breast cancers using breast‐conserving surgery (BCS) compared with the standard of mastectomy is uncertain. Inconsistencies relate to definitions, incidence, staging and intertumoral heterogeneity. The primary aim of this systematic review was to compare clinical outcomes after BCS versus mastectomy for MF and MC cancers, collectively defined as multiple ipsilateral breast cancers (MIBC). Methods Comprehensive electronic searches were undertaken to identify complete papers published in English between May 1988 and July 2015, primarily comparing clinical outcomes of BCS and mastectomy for MIBC. All study designs were included, and studies were appraised critically using the Newcastle–Ottawa Scale. The characteristics and results of identified studies were summarized. Results Twenty‐four retrospective studies were included in the review: 17 comparative studies and seven case series. They included 3537 women with MIBC undergoing BCS; breast cancers were defined as MF in 2677 women, MC in 292, and reported as MIBC in 568. Six studies evaluated MIBC treated by BCS or mastectomy, with locoregional recurrence (LRR) rates of 2–23 per cent after BCS at median follow‐up of 59·5 (i.q.r. 56–81) months. BCS and mastectomy showed apparently equivalent rates of LRR (risk ratio 0·94, 95 per cent c.i. 0·65 to 1·36). Thirteen studies compared BCS in women with MIBC versus those with unifocal cancers, reporting LRR rates of 2–40 per cent after BCS at a median follow‐up of 64 (i.q.r. 57–73) months. One high‐quality study reported 10‐year actuarial LRR rates of 5·5 per cent for BCS in 300 women versus 6·5 per cent for mastectomy among 887 women. Conclusion The available studies were mainly of moderate quality, historical and underpowered, with limited follow‐up and biased case selection favouring BCS rather than mastectomy for low‐risk patients. The evidence was inconclusive, weakening support for the St Gallen consensus and supporting a future randomized trial.

Abstract
AIMS To evaluate the predictive factors of birth weight (BW) of newborns of women with gestational diabetes mellitus (GDM). METHODS A cross-sectional study was performed among pregnant women with GDM treated in a public maternity unit, Brazil. We selected 283 pregnant women, with nutritional follow-up initiated till the 28th gestational week, singleton pregnancy, without chronic diseases and with birth weight information of the newborns. The predictive factors of BW were identified by multivariate linear regression. RESULTS Mean maternal age was 31.2 ± 5.8 years; 64.4% were non-white; 70.1% were pre-gestational overweight or obese. Mean BW was 3234.3 ± 478.8 g. An increase of 1 kg of weight in the first and third trimesters increased BW by 21 g (p = 0.01) and 27 g (p = 0.03), respectively. Similarly, the other predictive factors of BW were pre-gestational body mass index (β = 17.16, p = 0.02) and postprandial plasma glucose in the third trimester (β = 4.14, p = 0.008), in the model adjusted by gestational age at delivery (β = 194.68, p < 0.001). CONCLUSIONS The best predictors of BW were gestational age at birth, and maternal pre-gestational and gestational anthropometric characteristics. Maternal glycaemic levels may also influence BW. The results may contribute to a review of prenatal routines for pregnant women with GDM.

Abstract
Background: The Exercise for Health (EfH) trials were randomized, controlled trials designed to evaluate an 8-month pragmatic, exercise intervention, commencing 6 weeks post-surgery for women with newly diagnosed breast cancer residing in urban- or rural/regional areas. Outcomes for these exploratory analyses were overall survival (OS), breast cancer-specific survival (BCS) and disease-free survival (DFS). Methods: Consenting urban-residing women (EfH 1, n=194) and rural/regional-residing women (EfH 2, n=143) were randomized to exercise or usual care. Cox proportional hazards models were used to estimate hazard ratios (HR) and 95% confidence intervals (CI) for OS, BCS and DFS (exercise group, n=207, 65% urban women; usual care group, n=130, 46% urban women), with and without adjustment for prognostic factors including trial (urban/rural), age, body mass index, disease stage and presence of comorbidities. Further exploratory subgroup analyses were also conducted to assess whether effect on OS, BCS and DFS differed according to prognostic variables. Results: After a median follow-up of 8.3 years (IQR: 8.0-8.7 years) there were 11 (5.3%) deaths in the exercise group compared with 15 (11.5%) deaths in the usual care group (Table 1).

Note that women who had recurrence and died before follow-up only count once towards disease-free survival events.
HRs for the exercise group were: OS: 0.45, 95% CI=0.20-0.96; p=0.04; BCS: 0.61, 95% CI=0.25-1.46, p=0.26; and DFS: 0.66, 95% CI=0.38-1.17; p=0.16 (adjusted analyses yielded similar results). With the exception of BCS for those with a body mass index >30, all HRs for subgroup analyses favored exercise, with effect on OS for women of younger age (<55), those with stage II+ disease, and those with 1+ comorbidity at baseline significant (p<0.05). Effect of exercise on DFS was also significant (p<0.05) for urban women. Conclusion: Findings suggest that an individually-prescribed and monitored exercise program integrated during and beyond treatment for breast cancer, and that was designed to cater for all women, irrespective of place of residence and access to health services, has clear potential to influence survival.

Abstract
OBJECTIVE To evaluate the accuracy of information on pre-gestational weight, height, pre-gestational body mass index, and weight at the last prenatal appointment, according to maternal characteristics and sociodemographic and prenatal variables. METHODS The study was developed using data from the face-to-face questionnaire and prenatal card (gold standard) of the study "Birth in Brazil, 2011-2012". To evaluate the differences between the measured and self-reported anthropometric variables, we used the the Kruskal-Wallis test for the variables divided into quartiles. For the continuous variables, we used the Wilcoxon test, Bland-Altman plot, and average difference between the information measured and reported by the women. We estimated sensitivity and the intraclass correlation coefficient. RESULTS In the study, 17,093 women had the prenatal card. There was an underestimation of pre-gestational weight of 1.51 kg (SD = 3.44) and body mass index of 0.79 kg/m2 (SD = 1.72) and overestimation of height of 0.75 cm (SD = 3.03) and weight at the last appointment of 0.22 kg (SD = 2.09). The intraclass correlation coefficients (ICC) obtained for the anthropometric variables were: height (ICC = 0.89), pre-gestational weight (ICC = 0.96), pre-gestational body mass index (ICC = 0.92), and weight at the last appointment (ICC = 0.98). CONCLUSIONS The results suggest that the mentioned anthropometric variables were valid for the study population, and they may be used in studies of populations with similar characteristics.

Abstract
PURPOSE The Exercise for Health trials were randomised, controlled trials designed to evaluate an 8-month pragmatic exercise intervention, commencing 6 weeks post-surgery for women with newly diagnosed breast cancer residing in urban or rural/regional Australia. For these exploratory analyses, the primary and secondary outcomes were overall survival (OS) and disease-free survival (DFS), respectively. METHODS Consenting urban- (n = 194) and rural/regional-residing women (n = 143) were randomised to exercise (intervention delivered face-to-face or by telephone) or usual care. Cox proportional hazards models were used to estimate hazard ratios (HRs) and 95% confidence intervals (CI) for survival outcomes (exercise group, n = 207, 65% urban women; usual care group, n = 130, 46% urban women). RESULTS After a median follow-up of 8.3 years, there were 11 (5.3%) deaths in the exercise group compared with 15 (11.5%) deaths in the usual care group (OS HR for the exercise group: 0.45, 95% CI 0.20-0.96; p = 0.04). DFS events for the exercise versus usual care group were 25 (12.1%) and 23 (17.7%), respectively (HR: 0.66, 95% CI 0.38-1.17; p = 0.16). HRs for OS favoured exercise irrespective of age, body mass index, stage of disease, intervention compliance, and physical activity levels at 12 months post-diagnosis, although were stronger (p < 0.05) for younger women, women with stage II + disease, women with 1 + comorbidity at time of diagnosis, higher intervention compliance and for those who met national physical activity guidelines at 12 months post-diagnosis. CONCLUSION An exercise intervention delivered during and beyond treatment for breast cancer, and that was designed to cater for all women irrespective of place of residence and access to health services, has clear potential to benefit survival.

Abstract
OBJECTIVE To assess the impact of vitamin A supplementation on adult pregnant and puerperal women in Brazil regarding the content of vitamin A and secretory immunoglobulin A on colostrum and breast milk, in child's health conditions, and in mother-child binomial vitamin A status. METHODS A research was conducted in Medline, Scopus, Web of Science, and Lilacs electronic databases for the studies published between January 2000 and January 2014. The methodological quality of the studies was assessed according to Jadad scale. The study search was conducted in January 2014, independently by two authors. RESULTS Seven studies were found concerning the effects of vitamin A supplementation in the puerperal period on breast milk and infant morbidity. No study regarding pregnant women supplementation was found. The supplementation in the puerperal period raised the retinol content on breast milk, thus increasing the offer of vitamin A for the child and the concentration of secretory immunoglobulin A on colostrum. There was no description of effects on infant morbidity. CONCLUSION It seems that the advantages of postpartum supplementation were not established in the Brazilian program, although the supplementation contributes to a better nutritional status of vitamin A for both the child and the puerperal woman and increases the offer of vitamin A for the newborn through the breast milk.

Abstract
Pregnant women with Gestational Diabetes Mellitus (GDM) have a greater chance of developing Hypertensive Disorders of Pregnancy (HDP) by the effect of insulin resistance in nitric oxide action.This study aims to describe factors associated with the development of HDP in pregnant women with GDM, assisted in a public maternity hospital in Rio de Janeiro, Brazil. This is a cross-sectional study including 292 pregnant adult women with GDM assisted at Maternidade Escola of the Universidade Federal do Rio de Janeiro. The women were examined during pregnancy and postpartum. Data were collected between 2011 and 2014 from medical records and through in-person interviews. The Student t-test and the chi-square test were applied; additionally, the magnitude of the association between independents variables and HDP was estimated by logistic regression models. The occurrence of HDP was observed in 19.5% (n=57) of the evaluated women: 9.2% had pregnancy hypertension and 10.3% had preeclampsia. The chance of HDP was higher among women with GDM in a previous pregnancy (Odds Ratio-OR=3.8; Confidence Interval of 95%-95% CI: 1.1; 12.8) and among those who were 35 years old or older (OR 3.3; 95% CI: 1.2; 8.7) after controlling the effects of pre-gestational weight and dietary ingestion of calcium, riboflavin, thiamine, vitamin A and protein. Women that had any alteration in blood pressure in a previous pregnancy and those over 35 years old were under higher risk of HDP. The findings may help in the design of interventions aiming to prevent HDP in adult women.
