SARS-CoV-2 Footprints in the Placenta: What We Know after Three Years of the Pandemic.

As the COVID-19 pandemic continues into its third year, there is accumulating evidence on the consequences of maternal infection. Emerging data indicate increased obstetrics risks, including maternal complications, preterm births, impaired intrauterine fetal growth, hypertensive disorders, stillbirth, gestational diabetes, and a risk of developmental defects in neonates. Overall, controversial concerns still exist regarding the potential for vertical transmission. Histopathological examination of the placenta can represent a useful instrument for investigation and can contribute significant information regarding the possible immunohistopathological mechanisms involved in developing unfavorable perinatal outcomes. Based on current evidence, SARS-CoV-2 infection can affect placental tissue by inducing several specific changes. The level of placental involvement is considered one of the determining factors for unfavorable outcomes during pregnancy due to inflammation and vascular injuries contributing to complex cascade immunological and biological events; however, available evidence does not indicate a strong and absolute correlation between maternal infection, placental lesions, and obstetric outcomes. As existing studies are still limited, we further explore the placenta at three different levels, using histology, immunohistochemistry, and molecular genetics to understand the epidemiological and virological changes observed in the ongoing pandemic.

Valuing maternal, newborn, child and adolescent health for societal progress - Going beyond the economic orthodoxy of gross domestic product.

AIM: In view of the long-standing recognition that gross domestic product (GDP) does not capture the unremunerated work largely conducted by women upon which societal well-being depends, to discuss the implications for GDP of maternal, newborn, child and adolescent health (MNCAH), and its influences on health, well-being and prosperity across the life course and across generations. METHODS: A wide-ranging discussion of the informal think-tank The Venice Forum was held over two days, with inputs from invited experts in person and online. RESULTS: There was consensus that a strong case could be made for inclusion of unremunerated work largely conducted by women as a positive contribution to GDP in view of its impact on future health and prosperity, and conversely exclusion from GDP of outputs from industries which harm health. CONCLUSION: Taken with the current challenges from COVID, climate change and conflict, there is a compelling need to redefine economic progress through equitable models and metrics that incorporate short-/medium-/long-term societal value of activities that improve MNCAH.

Food insecurity, food deserts, reproduction and pregnancy: we should alert from now.

Food insecurity and food deserts are prominent global health problems, now exacerbated by current COVID-19 pandemic. Some evidence points to the importance of food security, particularly for women in their reproductive age. Women's health and their nutrition status, across the continuum of preconception to pregnancy and postpartum are critical aspects for ensuring positive gestation course and short-/long-term outcomes by affecting essential developmental pathways. Several adverse outcomes (both maternal and neonatal) were reported in scientific literature. Screening programs, new economic policies, implementation of assistance since preconception could be a good strategy to mitigate the negative consequences of food insecurity. Potential strategies could include addressing misconceptions about healthy maternal diet and breast milk adequacy, stress management, promote social support networks, and connecting to supplemental nutrition assistance programs.KEY POINTSFood insecurity (limited food access owing to cost) and desert foods (living in areas with low physical/personal access to nutritious food) are major public health concerns.Large geographical and within-country disparities, multiple socio-economic determinants.Childbearing age and pregnancy are groups at higher vulnerability to develop complications.Food insecurity negatively affects offspring health and development.Peri-conceptional window: an early clinical opportunity to screen and to apply preventive strategies.Help vulnerable groups to have access to more affordable nutritious food, educate and change unhealthy behaviors, adequate stress management, social support networks.

Opportunistic mycoses in COVID-19 patients/survivors: Epidemic inside a pandemic.

Being considered minor vexations, fungal infections hinder the life of about 15% of the world population superficially, with rare threats to life in case of invasive sepsis. A significant rise in the intrusive mycoses due to machiavellian fungal species is observed over the years due to increased pathology and fatality in people battling life-threatening diseases. Individuals undergoing therapy with immune suppressive drugs plus recovering from viral infections have shown to develop fungal sepsis as secondary infections while recovering or after. Currently, the whole world is fighting against the fright of Coronavirus disease (COVID-19), and corticosteroids being the primitive therapeutic to combat the COVID-19 inflammation, leads to an immune-compromised state, thereby allowing the not so harmful fungi to violate the immune barrier and flourish in the host. A wide range of fungal co-infection is observed in the survivors and patients of COVID-19. Fungal species of Candida, Aspergillus and Mucorales, are burdening the lives of COVID-19 patients/survivors in the form of Yellow/Green, White and Black fungus. This is the first article of its kind to assemble note on fungal infections seen in the current human health scenario till date and provides a strong message to the clinicians, researchers and physicians around the world "non-pathological fungus should not be dismissed as contaminants, they can quell immunocompromised hosts".

COVID-19 in pregnant women and children: Insights on clinical manifestations, complexities, and pathogenesis.

Pregnancy changes the body's immune system to counteract the spectrum of infections, including COVID-19, which can pose complications. Pregnant women are less likely to contract COVID-19 infections than the general public. However, pregnant women are at slightly increased risk of becoming severely unwell if they do catch COVID-19, and congenital conditions in pregnant women may worsen the state of infection and lead to critical stages and even mortality. The possibility of vertical transmission has been reported in only a few cases of COVID-19; however, it was not noted in cases of SARS and MERS. Vaccination coverage in pregnant women remains a challenge. Children are the next suspected and vulnerable population to acquire infection after the first and second waves. Children are disproportionately infected compared with older populations, but the severity of infection is less compared to adults. This review highlights the complexities of COVID-19 in pregnant women and the underlying reasons why children tend to be comparatively less severely affected. Ethnicity, nutrition, lifestyle, and therapeutics influence the severity of infection in children. Low expression of angiotensin-converting enzyme 2 receptors, indigenous virus competence, and maternal immunity is the first-line defense for children against COVID-19. Habituating herbal medicines from childhood may help support a robust and defensive immune system to counteract novel antigens and encourage healthy generations.

Equity in coronavirus disease 2019 vaccine development and deployment.

The coronavirus disease 2019 pandemic exposed weaknesses in multiple domains and widened gender-based inequalities across the world. It also stimulated extraordinary scientific achievement by bringing vaccines to the public in less than a year. In this article, we discuss the implications of current vaccination guidance for pregnant and lactating women, if their exclusion from the first wave of vaccine trials was justified, and if a change in the current vaccine development pathway is necessary. Pregnant and lactating women were not included in the initial severe acute respiratory syndrome coronavirus 2 vaccine trials. Therefore, perhaps unsurprisingly, the first vaccine regulatory approvals have been accompanied by inconsistent advice from public health, governmental, and professional authorities around the world. Denying vaccination to women who, although pregnant or breastfeeding, are fully capable of autonomous decision making is a throwback to a paternalistic era. Conversely, lack of evidence generated in a timely manner, upon which to make an informed decision, shifts responsibility from research sponsors and regulators and places the burden of decision making upon the woman and her healthcare advisor. The World Health Organization, the Task Force on Research Specific to Pregnant Women and Lactating Women, and others have highlighted the long-standing disadvantage experienced by women in relation to the development of vaccines and medicines. It is uncertain whether there was sufficient justification for excluding pregnant and lactating women from the initial severe acute respiratory syndrome coronavirus 2 vaccine trials. In future, we recommend that regulators mandate plans that describe the development pathway for new vaccines and medicines that address the needs of women who are pregnant or lactating. These should incorporate, at the outset, a careful consideration of the balance of the risks of exclusion from or inclusion in initial studies, patient and public perspectives, details of "developmental and reproductive toxicity" studies, and approaches to collect data systematically from participants who are unknowingly pregnant at the time of exposure. This requires careful consideration of any previous knowledge about the mode of action of the vaccine and the likelihood of toxicity or teratogenicity. We also support the view that the default position should be a "presumption of inclusion," with exclusion of women who are pregnant or lactating only if justified on specific, not generic, grounds. Finally, we recommend closer coordination across countries with the aim of issuing consistent public health advice.

Building resilient societies after COVID-19: the case for investing in maternal, neonatal, and child health.

Resilient societies respond rapidly and effectively to health challenges and the associated economic consequences, and adapt to be more responsive to future challenges. Although it is only possible to recognise resilience retrospectively, the COVID-19 pandemic has occurred at a point in human history when, uniquely, sufficient knowledge is available on the early-life determinants of health to indicate clearly that a focus on maternal, neonatal, and child health (MNCH) will promote later resilience. This knowledge offers an unprecedented opportunity to disrupt entrenched strategies and to reinvest in MNCH in the post-COVID-19 so-called new normal. Furthermore, analysis of the short-term, medium-term, and longer-term consequences of previous socioeconomic shocks provides important insights into those domains of MNCH, such as neurocognitive development and nutrition, for which investment will generate the greatest benefit. Such considerations apply to high-income countries (HICs) and low-income and middle-income countries (LMICs). However, implementing appropriate policies in the post-COVID-19 recovery period will be challenging and requires political commitment and public engagement.

О принципах работы перинатального стационара в условиях пандемии коронавируса

The rapid spread of COVID-19 and the large number of cases put a significant burden on the health systems of any developed country. Specialists in natural disasters and military medicine should be involved in the provision of medical care and observance of anti-epidemic measures. In some countries, including Italy, they were involved only after the situation was dramatically worsening with many clinical units and hospitals overloaded by infected patients. To curb the spread of COVID-19, most countries declared a state of emergency, and unprecedented measures have been taken to strengthen quarantine in suspected or positive symptomatic subjects. Nevertheless, the crisis associated with the unexpectedly global scale and tragedy of the pandemic and the inconsistency of actions of both society and individuals and specialized medical services, lead to insufficient effectiveness of the measures taken in a number of regions. In the present day, it is vital for every person to change its mindset - relying on personal responsibility to comply with all recommendations of quarantine and anti-epidemic measures, and to reorganize departments and resources of medical institutions at all levels in order to withstand the spread of infection and at the same time provide all those in need with the necessary and appropriate medical care. Particular attention should be paid to the obstetric care service, given that even in “normal” times, the obstetric hospital is an area of increased responsibility for the life and health of mother and child and future mankind. Fulfillment of existing orders, instructions of national and regional committees, international and national protocols and clinical protocols should undoubtedly lead to a positive result, but this requires additional training of medical personnel at all levels. The purpose of this review is to propose quick key strategies for reassessing the maternity and neonatal wards/ hospitals based on the experience of health systems and organizations which faced the spread of this new coronavirus;this advice may be applied along with binding tight instructions in obstetric hospitals in order to proactively respond to a likely wave of growth in COVID-19. Актуальность. Быстрое распространение COVID-19 и большое количество заболевших накладывает значительную нагрузку на системы здравоохранения развитых государств. В ряде стран к оказанию медицинской помощи и соблюдению противоэпидемических мероприятий привлекаются специалисты по стихийным бедствиям и военной медицине, однако в некоторых странах, в том числе в Италии, они были задействованы после того, как многие клинические подразделения и стационары были перегружены. Для сдерживания распространения COVID-19 большинство стран объявили чрезвычайное положение, были приняты беспрецедентные меры по усилению карантинных мероприятий. Тем не менее кризис, связанный с неожиданно глобальным масштабом и трагичностью пандемии, и несогласованность действий как общества и отдельных граждан, так и специализированных медицинских служб приводят к недостаточной эффективности проводимых мероприятий в ряде регионов. Особое внимание следует уделить службе родовспоможения, учитывая, что и в спокойное время акушерский стационар является зоной повышенной ответственности за жизнь и здоровье матери и ребенка. Исполнение действующих приказов, указаний национальных и региональных комитетов, международных/национальных и клинических протоколов, несомненно, приведет к положительному результату, но требует дополнительного обучения и тренировки медицинского персонала всех уровней. Цель обзора - предложить ключевые стратегии, основываясь на опыте регионов, ранее столкнувшихся с распространением нового коронавируса, которые могут быть быстро применены наряду с обязательными к исполнению действующими приказами и распоряжениями в акушерских стационарах, чтобы превентивно отреагировать на вероятную волну роста заболеваемости и носительства COVID-19.
