Introduction of human papillomavirus (HPV) vaccination has been slow in low-income and middle-income countries (LMICs) because of resource constraints and worldwide shortage of vaccine supplies. Selleck CQ31 To help inform WHO recommendations, we modelled various HPV vaccination strategies to examine the optimal use of limited vaccine supplies and best allocation of scarce resources in LMICs in the context of the WHO global call to eliminate cervical cancer as a public health problem.

In this mathematical modelling analysis, we developed HPV-ADVISE LMIC, a transmission-dynamic model of HPV infection and diseases calibrated to four LMICs India, Vietnam, Uganda, and Nigeria. For different vaccination strategies that encompassed use of a nine-valent vaccine (or a two-valent or four-valent vaccine assuming high cross-protection), we estimated three outcomes reduction in the age-standardised rate of cervical cancer, number of doses needed to prevent one case of cervical cancer (NNV; as a measure of efficiency), and the incs of the abstract see Supplementary Materials section.
An increased incidence of monozygotic twinning after a blastocyst transfer has been previously reported in assisted reproductive technology treatment. It is uncertain whether this phenomenon is due to the extended culture time, culture medium, or inherent blastocyst parameters.

This study aimed to investigate the association between blastocyst parameters (invitro culture time, blastocyst stage, and inner cell mass and trophectoderm grading) and the incidence of monozygotic twinning after assisted reproductive technology.

This was a retrospective cohort study employing data from a multicenter, large, electronic database from 4 academic hospitals. All clinical pregnancies after a single blastocyst transfer between January 2014 and February 2020 were included. Blastocyst morphology was evaluated based on the Gardner grading system, considering the blastocyst stage, and inner cell mass and trophectoderm grading (grades A, B, and C). Monozygotic twinning was defined as ≥2 fetal heartbeats in a single gestati cell mass and grade B or C trophectoderm (0.82%, as the reference) and the highest in blastocysts with grade B or C inner cell mass and grade A trophectoderm (2.40%; adjusted relative risk, 2.62; 95% confidence interval, 1.60-4.43). The incidence of monozygotic twinning in blastocysts with consistent inner cell mass or trophectoderm grading was somewhere in between (both A 1.58%; adjusted relative risk, 1.86 [95% confidence interval, 1.23-3.04]; both B or C 1.59%; adjusted relative risk, 1.84 [95% confidence interval, 1.29-2.90]).

Higher risk of monozygotic twinning was associated with blastocyst morphology specific to those blastocysts with loosely arranged inner cell mass cells combined with tightly packed trophectoderm cells.

The onset of the term human parturition involves myometrial gene expression changes to transform the uterus from a quiescent to a contractile phenotype. It is uncertain whether the same changes occur in the uterus during preterm labor.

This study aimed to compare the myometrial gene expression between term and preterm labor and to determine whether the presence of acute clinical chorioamnionitis or twin gestation affects these signatures.

Myometrial specimens were collected during cesarean delivery from the following 7 different groups of patients term not in labor (n=31), term labor (n=13), preterm not in labor (n=21), preterm labor with acute clinical chorioamnionitis (n=6), preterm labor with no acute clinical chorioamnionitis (n=9), twin preterm not in labor (n=8), and twin preterm labor with no acute clinical chorioamnionitis (n=5). RNA was extracted, reverse transcribed and quantitative polymerase chain reactions were performed on 44 candidate genes (with evidence for differential expression in huns associated with preterm labor are associated with a pattern of gene expression that is distinct from term labor. Therefore, preterm labor may be initiated by a different myometrial process or processes outside the myometrium.
Multidisciplinary care of placenta accreta spectrum cases improves pregnancy outcomes, but the specific components of such a multidisciplinary collaboration varies between institutions. As experience with placenta accreta spectrum increases, it is crucial to assess new surgical techniques and protocols to help improve maternal outcomes and to advocate for hospital resources.

This study aimed to assess a novel multidisciplinary protocol for the treatment of placenta accreta spectrum that comprises cesarean delivery, multivessel uterine embolization, and hysterectomy in a single procedure within a hybrid operative suite.

This was a matched prepost study of placenta accreta spectrum cases managed before (2010-2017) and after implementation of the Placenta Accreta Spectrum Treatment With Intraoperative Multivessel Embolization protocol (2018-2021) at a tertiary medical center. Historical cases were managed with internal iliac artery balloon placement in selected cases with the decision to inflate the ballooum Treatment With Intraoperative Multivessel Embolization protocol provides a definitive surgical method that warrants consideration by other centers specializing in placenta accreta spectrum treatment.
Previous analyses of trends in feeding indicators of children younger than 2 years have been limited to low-income and middle-income countries. We aimed to assess time trends in the consumption of different types of milk (breastmilk, formula, and animal milk) by children younger than 2 years from 2000 to 2019 at a global level.

In this time-series analysis, we combined cross-sectional data from 487 nationally representative surveys from low-income and middle-income countries and information from high-income countries to estimate seven infant and young child feeding indicators in up to 113 countries. Multilevel linear models were used in pooled analyses to estimate annual changes in feeding practices from 2000 to 2019 for country income groups and world regions.

For the absolute average annual changes, we found significant gains in any breastfeeding at age 6 months in high-income countries (1·29 percentage points [PPs] per year [95% CI 1·12 to 1·45]; p<0·0001) and at age 1 year in high-income countrie and south Asia. Animal milk consumption by children younger than 6 months decreased significantly (-0·41 PPs per year [-0·51 to -0·31]; p<0·0001) in low-income and middle-income countries.

We found some increases in exclusive and any breastfeeding at age 6 months in various regions and income groups, while formula consumption increased in upper-middle-income countries. To achieve the global target of 70% exclusive breastfeeding by 2030, however, rates of improvement will need to be accelerated.

Heart failure with reduced ejection fraction and atrial fibrillation commonly coexist. Most calcium channel blockers are not recommended in heart failure with reduced ejection fraction, but their use has been seldom evaluated. For patients with heart failure with reduced ejection fraction and comorbid atrial fibrillation, we sought to 1) determine the proportion discharged on contraindicated calcium channel blockers, 2) describe how clinicians' use of these medications at discharge have changed over time, and 3) identify predictors for contraindicated calcium channel blocker prescription at discharge.

We analyzed 395 patients discharged with heart failure with reduced ejection fraction and atrial fibrillation between 2008 and 2018. Discharge on a contraindicated calcium channel blocker (any calcium channel blocker except amlodipine) was the primary outcome. Changes in calcium channel blocker prescription over time were evaluated with a Cochran-Armitage trend test. Multivariable logistic regression was useheart failure with reduced ejection fraction and comorbid atrial fibrillation were discharged on a contraindicated calcium channel blocker, without change over time. Most patients were discharged on multiple atrioventricular nodal blockers, highlighting potential need for greater coordination between discharging physicians, pharmacists, and electrophysiology.The development of an effective vaccine against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the etiologic agent of coronavirus disease 2019 (COVID-19), is a global priority. Here, we compare the protective capacity of intranasal and intramuscular delivery of a chimpanzee adenovirus-vectored vaccine encoding a prefusion stabilized spike protein (chimpanzee adenovirus [ChAd]-SARS-CoV-2-S) in Golden Syrian hamsters. Although immunization with ChAd-SARS-CoV-2-S induces robust spike-protein-specific antibodies capable of neutralizing the virus, antibody levels in serum are higher in hamsters vaccinated by an intranasal compared to intramuscular route. Accordingly, against challenge with SARS-CoV-2, ChAd-SARS-CoV-2-S-immunized hamsters are protected against less weight loss and have reduced viral infection in nasal swabs and lungs, and reduced pathology and inflammatory gene expression in the lungs, compared to ChAd-control immunized hamsters. Intranasal immunization with ChAd-SARS-CoV-2-S provides superior protection against SARS-CoV-2 infection and inflammation in the upper respiratory tract. These findings support intranasal administration of the ChAd-SARS-CoV-2-S candidate vaccine to prevent SARS-CoV-2 infection, disease, and possibly transmission.Cells communicate with their environment via surface proteins and secreted factors. Unconventional protein secretion (UPS) is an evolutionarily conserved process, via which distinct cargo proteins are secreted upon stress. Most UPS types depend upon the Golgi-associated GRASP55 protein. However, its regulation and biological role remain poorly understood. Here, we show that the mechanistic target of rapamycin complex 1 (mTORC1) directly phosphorylates GRASP55 to maintain its Golgi localization, thus revealing a physiological role for mTORC1 at this organelle. Stimuli that inhibit mTORC1 cause GRASP55 dephosphorylation and relocalization to UPS compartments. Through multiple, unbiased, proteomic analyses, we identify numerous cargoes that follow this unconventional secretory route to reshape the cellular secretome and surfactome. Using MMP2 secretion as a proxy for UPS, we provide important insights on its regulation and physiological role. Collectively, our findings reveal the mTORC1-GRASP55 signaling hub as the integration point in stress signaling upstream of UPS and as a key coordinator of the cellular adaptation to stress.
