Preventing Obesity in Midlife Women: A Recommendation From the Women's Preventive Services Initiative.

DESCRIPTION: The Women's Preventive Services Initiative (WPSI), a national coalition of women's health professional organizations and patient advocacy representatives, developed a recommendation for counseling midlife women aged 40 to 60 years with normal or overweight body mass index (BMI; 18.5 to 29.9 kg/m2) to maintain weight or limit weight gain to prevent obesity with the long-term goals of optimizing health, function, and well-being. This recommendation is intended to guide clinical practice and coverage of clinical preventive health services for the Health Resources and Services Administration and other stakeholders. Clinicians providing preventive health care to women in primary care settings are the target audience for this recommendation. METHODS: The WPSI developed this recommendation after evaluating results of a systematic review of the effectiveness and harms of interventions to prevent weight gain and obesity in women aged 40 to 60 years without obesity. Seven randomized clinical trials including 51 638 participants and using various counseling and behavioral interventions were included. Trials indicated favorable weight changes with interventions that were statistically significantly different from control groups in 4 of 5 trials of counseling, but not in 2 trials of exercise. Few harms were reported. RECOMMENDATION: The WPSI recommends counseling midlife women aged 40 to 60 years with normal or overweight BMI (18.5 to 29.9 kg/m2) to maintain weight or limit weight gain to prevent obesity. Counseling may include individualized discussion of healthy eating and physical activity.

Endoscopic ultrasound-guided drainage of a pelvic abscess - An alternative use of lumen-apposing metallic stents.

The use of lumen-apposing metal stent is well defined for endoscopic ultrasound-guided drainage of pancreatic collections (e.g. WON). However, it is not yet a well-established approach in the management of postsurgical collections. We present an alternative application of LAMS for EUS drainage of pelvic abscess, showing that it is a safe and minimally invasive technique, with excellent clinical results. This technique should be considered as a drainage alternative in these scenarios due to its lower morbidity and mortality, opening a new era in the approach to these lesions.

Deconstructing Difflugia: The tangled evolution of lobose testate amoebae shells (Amoebozoa: Arcellinida) illustrates the importance of convergent evolution in protist phylogeny.

Protists, the micro-eukaryotes that are neither plants, animals nor fungi build up the greatest part of eukaryotic diversity on Earth. Yet, their evolutionary histories and patterns are still mostly ignored, and their complexity overlooked. Protists are often assumed to keep stable morphologies for long periods of time (morphological stasis). In this work, we test this paradigm taking Arcellinida testate amoebae as a model. We build a taxon-rich phylogeny based on two mitochondrial (COI and NADH) and one nuclear (SSU) gene, and reconstruct morphological evolution among clades. In addition, we prove the existence of mitochondrial mRNA editing for the COI gene. The trees show a lack of conservatism of shell outlines within the main clades, as well as a widespread occurrence of morphological convergences between far-related taxa. Our results refute, therefore, a widespread morphological stasis, which may be an artefact resulting from low taxon coverage. As a corollary, we also revise the groups systematics, notably by emending the large and highly polyphyletic genus Difflugia. These results lead, amongst others, to the erection of a new infraorder Cylindrothecina, as well as two new genera Cylindrifflugia and Golemanskia.

Biallelic mismatch repair deficiency - A rare and troublesome genetic syndrome.

Biallelic mismatch repair deficiency (BMMRD) is a rare autosomal recessive disorder characterized by numerous early-onset cancers, especially gastrointestinal tumors. Biallelic germline mutations in one of four mismatch repair (MMR) genes (MLH1, MSH2, MSH6, or PMS2) cause this devastating disease. Given the rarity of the syndrome, often-asymptomatic tumors, diagnosis is frequently unrecognized or delayed. A high degree of clinical awareness is needed to identify new cases. Immunohistochemical assessment of MMR protein expression and analysis of microsatellite instability are the first tools with which to initiate the study of this syndrome in solid malignancies. MMR immunohistochemical shows a hallmark pattern with absence of staining in both neoplastic and non-neoplastic cells for the biallelic mutated gene. We present a unique case of a young boy diagnosed with invasive colon adenocarcinoma and brain tumor, with classical BMMRD features, found to have biallelic pathogenic PMS2 mutations.

Screening for Anxiety in Adolescent and Adult Women: A Recommendation From the Women's Preventive Services Initiative.

DESCRIPTION: The Women's Preventive Services Initiative (WPSI), a national coalition of women's health professional organizations and patient representatives, developed a recommendation on screening for anxiety in adolescent and adult women to improve detection; achieve earlier diagnosis and treatment; and improve health, function, and well-being. The WPSI's recommendations are intended to guide clinical practice and coverage of services for the Health Resources and Services Administration and other stakeholders. The target audience for this recommendation includes all clinicians providing preventive health care to women, particularly in primary care settings. This recommendation applies to women and adolescent girls aged 13 years or older who are not currently diagnosed with anxiety disorders, including pregnant and postpartum women. METHODS: The WPSI developed this recommendation after evaluating results of a systematic review of the effectiveness of screening, accuracy of screening instruments, and benefits and harms of treatments in adolescent girls and adult women. No studies directly evaluated the overall effectiveness or harms of screening for anxiety. Twenty-seven screening instruments and their variations were moderately to highly accurate in identifying anxiety (33 individual studies and 2 systematic reviews; 171 studies total). Symptoms improved and relapse rates decreased with psychological therapies (246 randomized controlled trials [RCTs] in 5 systematic reviews) and with selective serotonin reuptake inhibitors or selective serotonin and norepinephrine reuptake inhibitors (126 RCTs in 3 systematic reviews). The WPSI also considered the effect of screening on symptom progression and identification of associated and underlying conditions, as well as implementation factors. RECOMMENDATION: The WPSI recommends screening for anxiety in women and adolescent girls aged 13 years or older who are not currently diagnosed with anxiety disorders, including pregnant and postpartum women. Optimal screening intervals are unknown, and clinical judgment should be used to determine frequency. When screening suggests the presence of anxiety, further evaluation is necessary to establish the diagnosis and determine appropriate treatment and follow-up.

A Prematurity Collaborative Birth Equity Consensus Statement for Mothers and Babies.

INTRODUCTION: In 2016, March of Dimes (MOD) launched its Prematurity Collaborative to engage a broad cross section of national experts to address persistent and widening racial disparities in preterm birth by achieving equity and demonstrated improvements in preterm birth. African-American and Native American women continue to have disproportionate rates of preterm birth and maternal death. As part of the Collaborative, MOD created the Health Equity Workgroup whose task was the creation of a scientific consensus statement articulating core values and a call to action to achieve equity in preterm birth utilizing health equity and social determinants of health frameworks. METHODS: Health Equity Workgroup members engaged in-person and virtually to discuss key determinant contributors and resolutions for disparate maternal and birth outcomes. Workgroup members then drafted the Birth Equity Consensus Statement that contained value statements and a call to action. The birth equity consensus statement was presented at professional conferences to seek broader support. This article highlights the background and context towards arriving at the core values and call to action, which are the two major components of the consensus statement and presents the core values and call to action themselves. RESULTS: The result was the creation of a birth equity consensus statement that highlights risks and protections of social determinants based on the prevailing science, and identifies promising solutions for reducing preterm birth and eliminating racial disparities. CONCLUSION: The birth equity consensus statement provides a mandate, guiding the work of March of Dimes and the broader MCH community, for equity-based research, practice, and policy advocacy at local, state, and federal levels. SIGNIFICANCE: This field report adds to the current knowledge base on racial and ethnic disparities in birth and maternal health outcomes. Research has documented the science behind eliminating health disparities. Scientists and practitioners should continue to explore in practice how the social determinants of birth and maternal health, which manifest historically and contemporarily, can be addressed.

Interpregnancy Care.

Interpregnancy care aims to maximize a woman's level of wellness not just in between pregnancies and during subsequent pregnancies, but also along her life course. Because the interpregnancy period is a continuum for overall health and wellness, all women of reproductive age who have been pregnant regardless of the outcome of their pregnancies (ie, miscarriage, abortion, preterm, full-term delivery), should receive interpregnancy care as a continuum from postpartum care. The initial components of interpregnancy care should include the components of postpartum care, such as reproductive life planning, screening for depression, vaccination, managing diabetes or hypertension if needed, education about future health, assisting the patient to develop a postpartum care team, and making plans for long-term medical care. In women with chronic medical conditions, interpregnancy care provides an opportunity to optimize health before a subsequent pregnancy. For women who will not have any future pregnancies, the period after pregnancy also affords an opportunity for secondary prevention and improvement of future health.

Screening for Urinary Incontinence in Women: A Recommendation From the Women's Preventive Services Initiative.

Description: Recommendation on screening for urinary incontinence in women by the Women's Preventive Services Initiative (WPSI), a national coalition of women's health professional organizations and patient representatives. The WPSI's recommendations are intended to guide clinical practice and coverage of services for the Health Resources and Services Administration and other stakeholders. The target audience for this recommendation includes all clinicians providing preventive health care for women, particularly in primary care settings. This recommendation applies to women of all ages, as well as adolescents. Methods: The WPSI developed this recommendation after evaluating evidence regarding the benefits and harms of screening for urinary incontinence in women. The evaluation included a systematic review of the accuracy of screening instruments and the benefits and harms of treatments. Indirect evidence was used to link screening and health outcomes in the chain of evidence that might support screening in the absence of direct evidence. The WPSI also considered the effect of screening on symptom progression and avoidance of costly and complex treatments, as well as implementation factors. Recommendation: The WPSI recommends screening women for urinary incontinence annually. Screening ideally should assess whether women experience urinary incontinence and whether it affects their activities and quality of life. The WPSI recommends referring women for further evaluation and treatment if indicated.

Central nervous system infections caused by varicella-zoster virus.

We carried out a clinical and epidemiological study of adult patients with varicella-zoster virus central nervous system infection diagnosed by PCR in cerebrospinal fluid. Twenty-six patients were included. Twelve (46.2 %) patients were diagnosed with meningitis and fourteen (53.8 %) with meningoencephalitis. Twelve (46.2 %) had cranial nerves involvement (mainly the facial (VII) and vestibulocochlear (VIII) nerves), six (23.1 %) had cerebellar involvement, fourteen (53.8 %) had rash, and four (15.4 %) developed Ramsay Hunt syndrome. Three (11.5 %) patients had sequelae. Length of stay was significantly lower in patients diagnosed with meningitis and treatment with acyclovir was more frequent in patients diagnosed with meningoencephalitis. We believe routine detection of varicella-zoster virus, regardless of the presence of rash, is important because the patient may benefit from a different clinical management.

Endophytic species of Colletotrichum associated with cashew tree in northeastern Brazil.

Anthracnose caused by Colletotrichum is the most severe and widely occurring cashew disease in Brazil. Colletotrichum species are commonly found as pathogens, endophytes and occasionally as saprophytes in a wide range of hosts. The endophytic species associated with cashew trees are poorly studied. In this study, we report the Colletotrichum endophytic species associated with cashew trees in two locations in the state of Pernambuco, their prevalence in different plant organs (leaves, veins, branches and inflorescences), and compare the species in terms of pathogenicity and aggressiveness using different inoculation methods (wounded × unwounded). Six species of Colletotrichum were identified according to multilocus phylogenetic analyses, including Colletotrichum asianum, Colletotrichum chrysophilum, Colletotrichum karsti, Colletotrichum siamense, Colletotrichum theobromicola, and Colletotrichum tropicale. There were differences in the percentage of isolation in relation to the prevalence of colonized tissues and collection locations. C. tropicale was the prevalent species in both geographic areas and plant tissues collected, with no pattern of distribution of species between areas and plant tissues. All isolates were pathogenic in injured tissues of cashew plants. The best method to test the pathogenicity of Colletotrichum species was utilizing the combination of leaves + presence of wounds + conidial suspension, as it better represents the natural infection process. C. siamense was the most aggressive species.

Reducing the global burden of cerebral venous thrombosis: An international research agenda.

BACKGROUND: Due to the rarity of cerebral venous thrombosis (CVT), performing high-quality scientific research in this field is challenging. Providing answers to unresolved research questions will improve prevention, diagnosis, and treatment, and ultimately translate to a better outcome of patients with CVT. We present an international research agenda, in which the most important research questions in the field of CVT are prioritized. AIMS: This research agenda has three distinct goals: (1) to provide inspiration and focus to research on CVT for the coming years, (2) to reinforce international collaboration, and (3) to facilitate the acquisition of research funding. SUMMARY OF REVIEW: This international research agenda is the result of a research summit organized by the International Cerebral Venous Thrombosis Consortium in Amsterdam, the Netherlands, in June 2023. The summit brought together 45 participants from 15 countries including clinical researchers from various disciplines, patients who previously suffered from CVT, and delegates from industry and non-profit funding organizations. The research agenda is categorized into six pre-specified themes: (1) epidemiology and clinical features, (2) life after CVT, (3) neuroimaging and diagnosis, (4) pathophysiology, (5) medical treatment, and (6) endovascular treatment. For each theme, we present two to four research questions, followed by a brief substantiation per question. The research questions were prioritized by the participants of the summit through consensus discussion. CONCLUSIONS: This international research agenda provides an overview of the most burning research questions on CVT. Answering these questions will advance our understanding and management of CVT, which will ultimately lead to improved outcomes for CVT patients worldwide.

Predictors of Mortality in Patients with Infections Due to Carbapenem-Resistant Gram-Negative Bacteria.

INTRODUCTION: Infections caused by carbapenem-resistant Gram-negative bacteria (CR-GNB) are a significant cause of mortality and represent a serious challenge to health systems. The early identification of mortality predictors could guide appropriate treatment and follow-up. We aimed to identify the factors associated with 90-day all-cause mortality in patients with CR-GNB infections. METHODS: We conducted a cohort study from 1 January 2019 to 30 April 2022. The primary outcome was death from any cause during the first 90 days after the date of the first CR-GNB-positive culture. Secondary outcomes included infection relapse, invasive mechanical ventilation during follow-up, need for additional source control, acute kidney injury, Clostridioides difficile infection, and all-cause hospital admission after initial discharge. Bivariate and multivariate Cox-proportional hazards models were constructed to identify the factors independently associated with 90-day all-cause mortality. RESULTS: A total of 225 patients with CR-GNB infections were included. Death occurred in 76 (34%) cases. The most-reported comorbidities were immunosuppression (43%), arterial hypertension (35%), and COVID-19 (25%). The median length of stay in survivors was 18 days (IQR 10-34). Mechanical ventilation and ICU admission after diagnosis occurred in 8% and 11% of cases, respectively. Both infection relapse and rehospitalisation occurred in 18% of cases. C. difficile infection was diagnosed in 4% of cases. Acute kidney injury was documented in 22% of patients. Mechanical ventilation after diagnosis, ICU admission after diagnosis, and acute kidney injury in the first ten days of appropriate treatment were more frequently reported among non-survivors. In the multivariate analysis, age (HR 1.19 (95%CI 1.00-1.83)), immunosuppression (HR 1.84 (95%CI 1.06-3.18)), and septic shock at diagnosis (HR 2.40 (95% 1.41-4.08)) had an independent association with death during the first 90 days after the CR-GNB infection diagnosis. Receiving antibiogram-guided appropriate treatment was independently associated with a lower risk of death (HR 0.25 (95%CI 0.14-0.46)). CONCLUSIONS: The presence of advanced age, immunosuppression, septic shock at diagnosis, and inappropriate treatment are associated with higher 90-day all-cause mortality in hospitalised patients with infections due to CR-GNB. Recognition of the risk factors for adverse outcomes could further assist in patient care and the design of interventional studies that address the severe and widespread problem that is carbapenem resistance.

Growing Healthy Together: A Randomized Clinical Trial Using Parent Mentors for Early Childhood Obesity in Low-Income, Latino Families.

Background: Parent mentors are a potential community-based mechanism for delivering behavioral interventions. For communities at a higher risk of obesity and challenges with access to care, such as migrant and seasonal farm workers, this may be an effective intervention for obesity. This study examined the effect of parent mentors on weight outcomes. Methods: This randomized clinical trial assigned parents of 2- to 5 year-old children enrolled in Head Start 1:1:1 to control, a parent mentor teaching We Can!, or a parent mentor teaching an intervention derived from positive deviance methods. The parent mentor arms were designed to have weekly interactions and monthly community meetings over 6 months. The primary outcome was change in adiposity, as measured by body mass indices. Results: We randomized 188 parents, and 155 completed the 6-month visit. Most parents, 107 (58%), had less than a high school education, and 170 (90%) reported Latino ethnicity. In the intention-to-treat analysis, no difference between the groups was observed for change in percent distance from the median or BMI z-score. The median number of interactions was 14 (IQR 10-20) over 6 months for those who did engage, though 24 of 118 (20%) had no interaction. Those with no interactions in We Can! had a mean increase in change from median of 6.7 [standard deviation (SD) = 8.2]; those with higher participation experienced a 0.4 (SD = 9.2) change, p = 0.04. Conclusions: Parent mentors were not effective in changing the adiposity indices in this study overall, with some evidence of efficacy after accounting for participation. Clinicaltrials.gov registration number: NCT03330743.

AddTag, a two-step approach with supporting software package that facilitates CRISPR/Cas-mediated precision genome editing.

CRISPR/Cas-induced genome editing is a powerful tool for genetic engineering, however, targeting constraints limit which loci are editable with this method. Since the length of a DNA sequence impacts the likelihood it overlaps a unique target site, precision editing of small genomic features with CRISPR/Cas remains an obstacle. We introduce a two-step genome editing strategy that virtually eliminates CRISPR/Cas targeting constraints and facilitates precision genome editing of elements as short as a single base-pair at virtually any locus in any organism that supports CRISPR/Cas-induced genome editing. Our two-step approach first replaces the locus of interest with an "AddTag" sequence, which is subsequently replaced with any engineered sequence, and thus circumvents the need for direct overlap with a unique CRISPR/Cas target site. In this study, we demonstrate the feasibility of our approach by editing transcription factor binding sites within Candida albicans that could not be targeted directly using the traditional gene-editing approach. We also demonstrate the utility of the AddTag approach for combinatorial genome editing and gene complementation analysis, and we present a software package that automates the design of AddTag editing.

Microbiome and oral squamous cell carcinoma: a possible interplay on iron metabolism and its impact on tumor microenvironment.

There is increasing evidence showing positive association between changes in oral microbiome and the occurrence of oral squamous cell carcinoma (OSCC). Alcohol- and nicotine-related products can induce microbial changes but are still unknown if these changes are related to cancerous lesion sites. In an attempt to understand how these changes can influence the OSCC development and maintenance, the aim of this study was to investigate the oral microbiome linked with OSCC as well as to identify functional signatures and associate them with healthy or precancerous and cancerous sites. Our group used data of oral microbiomes available in public repositories. The analysis included data of oral microbiomes from electronic cigarette users, alcohol consumers, and precancerous and OSCC samples. An R-based pipeline was used for taxonomic and functional prediction analysis. The Streptococcus spp. genus was the main class identified in the healthy group. Haemophilus spp. predominated in precancerous lesions. OSCC samples revealed a higher relative abundance compared with the other groups, represented by an increased proportion of Fusobacterium spp., Prevotella spp., Haemophilus spp., and Campylobacter spp. Venn diagram analysis showed 52 genera exclusive of OSCC samples. Both precancerous and OSCC samples seemed to present a specific associated functional pattern. They were menaquinone-dependent protoporphyrinogen oxidase pattern enhanced in the former and both 3',5'-cyclic-nucleotide phosphodiesterase (purine metabolism) and iron(III) transport system ATP-binding protein enhanced in the latter. We conclude that although precancerous and OSCC samples present some differences on microbial profile, both microbiomes act as "iron chelators-like" potentially contributing to tumor growth.

Preconception Health: Changing the Paradigm on Well-woman Health.

An investment in assuring the health of women, before pregnancy, can reap improved health for women, children, and their families. A paradigm shift of health must occur if perinatal outcomes are to improve, moving beyond reactive care to preventive or preconception care. Preconception health is centered on an assumption a woman is planning on becoming pregnant. But for many women, pregnancy is unplanned and medical conditions may have a negative impact on the trajectory of pregnancy and health. A new paradigm focusing on prevention and wellness can prepare women for lifelong health and healthy perinatal outcomes.

Seeking coherence between 'mobile learning' applications and the everyday lives of medical residents.

INTRODUCTION: The role of technology in health professions education has received increased research attention. Research has examined the interaction between humans and technology, focusing on the mutual influence between people and technology. Little attention has been given to the role of motivation and incentives in how learning technologies are used in relation to daily activities. This research aims to understand the relationship between medical-learning technology and its users. METHODS: A mixed-method case study of a new medical-learning mobile application (app) for family medicine residents was undertaken at a Canadian university hospital. The Information Assessment Method is a custom-made app to help residents prepare for the College of Family Physicians of Canada licensing examination. Residents' use of the app was tracked over a 7-month period and individual, semi-structured interviews were conducted with users. Data were thematically analyzed and correlated with app use data. RESULTS: Factors identified as shaping residents' mobile app use for learning, included: efficiency, mobility and resonance with life context; credibility of information retrieved; and relevance of content. Most influential was stage of residency. Second-year residents were more selective and strategic than first-year residents in their app use. DISCUSSION: An emphasis on coherence between self-directed learning and externally dictated learning provides a framework for understanding the relationship between users and mobile-learning technology. This framework can guide the design, implementation and evaluation of learning interventions for healthcare professionals and learners.

Women's Preventive Services Initiative's Well-Woman Chart: A Summary of Preventive Health Recommendations for Women.

The Well-Woman Chart summarizes current recommendations for preventive health services for women from adolescence and continuing across the lifespan. It was developed by the Women's Preventive Services Initiative, a national collaborative of women's health professional organizations and patient representatives. The Well-Woman Chart includes current clinical guidelines from the U.S. Preventive Services Task Force, Bright Futures from the American Academy of Pediatrics, and the Women's Preventive Services Initiative that are covered with no cost-sharing for public and most private insurance plans under the prevention service mandate of the Affordable Care Act. The structure of the Well-Woman Chart is based on age intervals and pregnancy status categories that align with existing recommendations. The target audience for the Well-Woman Chart is all clinicians providing preventive health care for women, particularly in primary care settings, and patients affected by the recommendations. The preventive services recommendations apply to females 13 years of age and older and pregnant females of any age. The Well-Woman Chart provides clinical guidance for screening, counseling, and other recommended preventive services for women during health care visits based on age, pregnancy status, and risk factors.
