Understanding Attitudes of Postpartum Cisgender Women Toward Integration of HIV Prevention Services into Routine Prenatal and Postpartum Sexual Health Discussions.

Oral pre-exposure prophylaxis (PrEP) is an effective, user-controlled method for HIV prevention. However, awareness, uptake, and adherence to PrEP remain low among cisgender women (CGW). The prenatal and postpartum periods present an opportunity for delivery of comprehensive sexual health services that include HIV prevention education and services. However, little is known about postpartum CGW's attitudes toward integration of HIV prevention education and services into obstetric care in the US. We conducted semistructured interviews with 20 postpartum CGW in the Bronx, NY from July to November 2022 to explore their experiences with prenatal and postpartum sexual health care, examine their attitudes toward integration of HIV prevention services into obstetric sexual health care, and identify components of future implementation strategies. Transcripts were analyzed thematically using a framework approach. Among CGW interviewed, fewer than half reported prior knowledge of PrEP. Ten participants preferred long-acting injectable PrEP relative to six who preferred daily oral PrEP. Most participants reported no discussion of sex with their provider during pregnancy, and when discussions occurred, they focused on permission or prohibition of sexual activity. Participants described a reliance on providers to lead prenatal sexual health discussions. Even when not perceived as personally relevant, most respondents valued education on HIV prevention and PrEP services. In the postpartum period, sexual health discussions were similarly limited despite participants describing complex experiential sexual health concerns. This study supports the potential for integration of HIV prevention education and services into routine prenatal and postpartum sexual health discussions in an area of high HIV prevalence in the US.

Viable Leishmania parasites in the absence of an in vitro IFN-γ response in asymptomatic carriers.

Asymptomatic infection (the absence or inapparent signs and symptoms) has been observed in many endemic areas of leishmaniasis, however, little is known about the parasitological and immunological factors associated with this type of infection. This study aimed to identify the in vitro expression of IFN-γ in asymptomatic carriers of viable Leishmania parasites. Asymptomatic infection was identified using the Montenegro skin test in an at-risk population from Yucatan, Mexico. Parasite viability was evinced in the blood by 7SL RNA transcripts amplification. The expression of mRNA IFN-γ was analyzed in peripheral blood mononuclear cells stimulated with soluble Leishmania antigen, using RT-qPCR. Parasite viability was observed in 33.3 % (5/15) of asymptomatic subjects. No differences were found in the expression of IFN-γ between asymptomatic and healthy subjects, and no correlation was found between the presence of viable parasites and the expression of IFN-γ. This study demonstrates the persistence of Leishmania parasites in the absence of an in vitro IFN-γ response in asymptomatic carriers from Mexico.

Clinical and laboratory features of rickettsioses in Yucatan, Mexico.

Rickettsia species are obligate intracellular bacteria that can cause mild to severe human disease. Based on phylogeny, clinical symptoms, and antigenic properties, rickettsiae are classified into four groups. Infections by these agents are characterized by clinical symptoms ranging from self-limited to severe and even fatal febrile illnesses, depending on the Rickettsia spp. involved, the patient's predisposition, and timely medical care. The present study aimed to characterize rickettsial diseases in Yucatan according to clinical and laboratory features appearing in medical records corresponding to 427 samples taken between 2015 and 2018. A study was conducted over the period 2015-2018 on 427 samples. Clinical and laboratory features were documented from the patients' medical records. For molecular diagnosis, blood was collected in 3.8 % sodium citrate as anticoagulant, and DNA was extracted. Single-step and nested PCR amplification was performed using genus-specific primers for the rickettsial 17kDa and ompB genes. The amplicons obtained were purified and sequenced. A total of 22.7 % (97/427) positive cases of Rickettsia spp. were identified by PCR from 14.15 % (15/106) of the municipalities in Yucatan. 75.2 % (73/97) of the cases were from the city of Merida during the autumn (September-December). The age groups with the highest frequency of confirmed cases were pediatric (5-14 years) (57.7 %) and adults (25-49 years) (42.2 %). There were six fatal cases in children, one associated with R. typhi and five with R. rickettsii. In non-fatal cases, 32.9 % (32/97) corresponded to the spotted fever group (SFG), and 60.8 % (59/97) to the typhus group (TG). Significant differences in signs, and laboratory data, were observed between the pediatric and adult populations. For the treatment of patients, oral and intravenous doxycycline was used in severe hospitalized cases. Typhus group and spotted fever group Rickettsiae are endemic pathological agents found in urban and rural areas of our region. Molecular identification allows for greater diagnostic accuracy and timely treatment and consequently a better prognosis. It is necessary to implement or reinforce measures focused on the dissemination of knowledge regarding rickettsial diseases and their prevention.

Viable Leishmania parasites in the absence of an in vitro IFN-γ response in asymptomatic carriers

Recurrent activity in neuronal avalanches.

A new statistical analysis of large neuronal avalanches observed in mouse and rat brain tissues reveals a substantial degree of recurrent activity and cyclic patterns of activation not seen in smaller avalanches. To explain these observations, we adapted a model of structural weakening in materials. In this model, dynamical weakening of neuron firing thresholds closely replicates experimental avalanche size distributions, firing number distributions, and patterns of cyclic activity. This agreement between model and data suggests that a mechanism like dynamical weakening plays a key role in recurrent activity found in large neuronal avalanches. We expect these results to illuminate the causes and dynamics of large avalanches, like those seen in seizures.

First detection of Leishmania DNA in Lutzomyia longipalpis sensu lato (Diptera: Phlebotominae) in southem Mexico.

Background & objectives: Lutzomyia longipalpis sensu lato is an important vector of Leishmania infantum, the causative agent of visceral leishmaniasis (VL) in Latin America. In Mexico, this species has been recorded in endemic areas of leishmaniasis transmission, but it has never been detected as infected with Leishmania sp. This study aimed to explore the presence of Leishmania DNA in Lutzomyia longipalpis s.l. from samples collected with a human baited trap from an endemic region of leishmaniasis in southeastern Mexico. Methods: This is a prospective study where a total of 45 specimens of Lu. longipalpis s.l. collected in two sites of Yucatan state with records of leishmaniasis were tested. The nuclear ribosomal Internal Transcribed Spacer was amplified for the detection of Leishmania DNA. Results: Two females were positive for Leishmania DNA. None of the specimens positive for parasite DNA were found fed or gravid. Our finding represents the first record of infection by Leishmania in Lu. longipalpis s.l. for the country. Interpretation & conclusion: More studies are necessary to understand the potential role of this vector species in the transmission cycle of the causative agent of leishmaniasis in the southeastern and other regions of Mexico.

Mono- and biallelic germline variants of DNA glycosylase genes in colon adenomatous polyposis families from two continents.

Recently, biallelic germline variants of the DNA glycosylase genes MUTYH and NTHL1 were linked to polyposis susceptibility. Significant fractions remain without a molecular explanation, warranting searches for underlying causes. We used exome sequencing to investigate clinically well-defined adenomatous polyposis cases and families from Finland (N=34), Chile (N=21), and Argentina (N=12), all with known susceptibility genes excluded. Nine index cases (13%) revealed germline variants with proven or possible pathogenicity in the DNA glycosylase genes, involving NEIL1 (mono- or biallelic) in 3 cases, MUTYH (monoallelic) in 3 cases, NTHL1 (biallelic) in 1 case, and OGG1 (monoallelic) in 2 cases. NTHL1 was affected with the well-established, pathogenic c.268C>T, p.(Gln90Ter) variant. A recurrent heterozygous NEIL1 c.506G>A, p.(Gly169Asp) variant was observed in two families. In a Finnish family, the variant occurred in trans with a truncating NEIL1 variant (c.821delT). In an Argentine family, the variant co-occurred with a genomic deletion of exons 2 - 11 of PMS2. Mutational signatures in tumor tissues complied with biological functions reported for NEIL1. Our results suggest that germline variants in DNA glycosylase genes may occur in a non-negligible proportion of unexplained colon polyposis cases and may predispose to tumor development.

Women Trust Their OBGYNs to Provide Preexposure Prophylaxis: An Opportunity for HIV Prevention.

Objective: The objective of this study was to understand how women perceive the role of their Obstetrician and Gynecologist (OBGYN) in screening for and providing preexposure prophylaxis (PrEP) for HIV prevention. Methods: We recruited women ages 18-45 years receiving obstetric or gynecological care at an academic medical center in the Bronx, NY. Thirty participants were enrolled: 10 seeking care for family planning, 10 seeking prenatal care, and 10 seeking care for a sexually transmitted infection. We screened participants for HIV acquisition risk using a PrEP screening tool. We conducted face-to-face, semi-structured interviews, which were audio-recorded, transcribed, and entered into Dedoose for analysis of themes using a grounded theory approach. Results: Sixty percent of the participants were Latinx and 33% African American. Seventy percent had one or more risk factors for HIV acquisition based on the PrEP screening tool, indicating they would benefit from a PrEP discussion. Three main themes emerged from the analysis of interview data. Participants viewed OBGYNs as experts in sexual and reproductive healthcare and believed they were experts in PrEP. Participants were concerned about "PrEP stigma", being judged by their clinicians as being sexually promiscuous if they expressed a need for PrEP. Lastly, when participants trusted their OBGYN, that trust became a facilitator for women to consider PrEP and offset stigma as a barrier to identifying patients who are candidates for PrEP. Conclusion: Women established in care with an OBGYN are enthusiastic about having access to PrEP services incorporated into their sexual and reproductive healthcare. A universal approach to HIV prevention would avert stigma surrounding HIV care and prevention.

Leishmania (Leishmania) mexicana Infection in Wild Rodents from an Emergent Focus of Cutaneous Leishmaniasis in Yucatan, Mexico.

In 2015, emergent cases of localized cutaneous leishmaniasis (LCL) were reported in Tinum, Yucatan, Mexico. As part of an eco-epidemiological study to characterize the elements that trigger Leishmania infection in that area, we conducted a field study to investigate the occurrence of Leishmania infection in wild rodents. From November 2019 to February 2020, rodents were caught from three sites located in the municipality of Tinum, Yucatan. For each specimen, clinical signs suggestive of Leishmania infection were recorded. Samples from the tail, liver, and spleen were taken for the identification of Leishmania DNA by PCR. Twenty rodents belonging to two species were caught including Heteromys gaumeri (55%, 11/20) and Ototylomys phyllotis (45%, 9/20). Fifty-five percent of the animals presented white spots on the tail, 15% had splenomegaly, and 5% had hepatomegaly. Fifty-five percent (11/20) of the animals were found infected by Leishmania. Heteromys gaumeri was caught in all trapping sites and was the most infected species (63.6%, 7/11). The percentage of infection for O. phyllotis was 44.4% (4/9). Leishmania (Leishmania) mexicana was identified as the infecting species in two H. gaumeri. This study provides, for the first time, evidence of Leishmania infection in wild rodents from the Yucatan state. Heteromys gaumeri and O. phyllotis may be involved in the transmission cycle of L. mexicana in this emergent focus; however, further longitudinal studies are needed to confirm their role as primary reservoirs.

"Being able to do whatever you wanna do as a woman is important:" a qualitative exploration of contraception as a frame of reference for HIV prevention with PrEP.

BACKGROUND: Use of HIV PrEP (pre-exposure prophylaxis) is a strategic tool in the effort to end the HIV epidemic. 20% of new HIV infections in the US are among cis-gender women, yet they comprise only 5% of all PrEP users. Black women disproportionately bear the burden of new HIV acquisition and accounted for almost 60% of new HIV diagnoses among women in 2018. Increasing understanding and uptake of PrEP among women at risk of HIV acquisition in alignment with their reproductive values and preferences is key to increasing PrEP uptake and decreasing HIV burden in this population. OBJECTIVE: This study examines how experiences with contraception among women of color shape their perceptions and preferences regarding HIV PrEP to inform counseling that aligns with their reproductive values. METHODS: Women aged 18-45 who self-identified as Black or Latina were recruited at an academic medical center in the Bronx from June 2018 to July 2019. We enrolled 30 participants seeking family planning care (10), prenatal care (10), or care for sexually transmitted infections (10). Participants completed a brief written survey assessing their risk of HIV acquisition. Semi-structured, face-to-face interviews were then audio-recorded, transcribed, and entered into Dedoose. Grounded theory and constant comparison approaches were used to analyze the data. RESULTS: Twenty-one participants (70%) screened positive for HIV acquisition risk. Four had received information on PrEP from a medical provider prior to the interview. Three themes emerged from the qualitative analysis: (1) Similar to oral contraception, women conceptualized PrEP as a "daily pill" to support their reproductive health; (2) Women perceived PrEP as a tool to support autonomy and pleasure in their sexual health; (3) Like birth control, women desired multiple delivery options for HIV prophylaxis. CONCLUSIONS: Contraception may serve as a frame of reference when counseling about PrEP among cis-women at risk of acquiring HIV. Our study suggests that this approach re-contextualizes counseling on PrEP within a sex-positive framework that prioritizes pleasure, safety, and autonomy as integral to sexual and reproductive wellness. Consideration of historically marginalized women's experiences with contraception and reproductive values may facilitate their use of PrEP.

PrEP (pre-exposure prophylaxis) is a medicine taken daily by people at risk of getting HIV from sex or injection drug use. Although PrEP is a safe and effective medication for women, the use of PrEP remains exceedingly low among cis-gender women at risk of HIV in the US. This study examines how experiences with contraception among women of color, who disproportionately bear the burden of HIV acquisition, shape their perceptions and preferences regarding PrEP. We interviewed 30 women who self-identified as Black or Latina at an academic medical center in the Bronx. Similar to oral contraception, women in this study conceptualized PrEP as a "daily pill" to support their reproductive health. This report details how women's experiences with contraception may serve as the foundation to re-contextualize conversations on PrEP within a sex-positive framework that prioritizes pleasure, safety, and autonomy as integral to sexual and reproductive wellness.

Telemedicine for Contraceptive Counseling During the COVID-19 Pandemic: Referral Patterns and Attendance at Follow-Up Visits.

Objective: To describe referral patterns and attendance at follow-up visits for patients who received contraceptive counseling via telemedicine during the COVID-19 pandemic. Study Design: This is a prospective study of patients seen remotely during the early phase of the COVID-19 pandemic in New York City. We tracked referral rates, referral reasons, in-person visit show rates, and additional visits. We also administered a patient survey at 6 months. Using Stata SE 16, we conducted a multivariable modified Poisson regression with robust error variances to examine the predictors of attending an in-person visit within 30 days. Results: We included 169 patients who had visits between April 1 and June 30, 2020. Of these, 109 (64.5%) were referred for in-person visits, and 83 (76.1%) of those referred attended within 30 days. The most common reasons for referral were long-acting reversible contraception (LARC) removal and insertion. The relative risk (RR) of attending a visit within 30 days of referral was 24% higher for those referred for LARC removal compared with those referred for other reasons (RR 1.24, 95% confidence interval [CI] 1.08-1.69), and it was 29% lower for those aged 18-25 compared with those in the reference age (26-35) group (RR 0.71, 95% CI 0.51-0.98). At 6 months, 69.4% of patients were still using the method they decided on at the telemedicine visit, and 44.4% would choose telemedicine for their next contraception visit. Conclusions: Approximately one third of patients seeking contraceptive counseling via telemedicine did not seek additional in-person visits over a 6-month period. Among the patients referred for in-person visits, referral reason and patient age may impact attendance rates.

Breastfeeding and contraception counseling: a qualitative study.

BACKGROUND: The objectives of this qualitative study were to better understand women's experiences regarding contraceptive choice, breastfeeding intentions and the relationship between the two. Women are routinely presented with counseling on breastfeeding and contraception throughout their prenatal and postpartum care, but little is published on patients' own priorities, desires and experiences of this peripartum counseling. This article aims to address this gap in the literature. METHODS: Semi-structured interviews were conducted with patients in the immediate postpartum period. The interview guide explored: 1) timing and content of contraceptive counseling; 2) breastfeeding goals and expectations; 3) reasons for contraceptive choices; and 4) recommendations for counseling. Interview transcripts were coded to identify themes and analyzed. RESULTS: Twenty interviews were conducted. The participants were reflective of our patient population in the Bronx, with ninety percent using Medicaid for insurance and fifteen percent concerned about food security in the past month, well-validated questions reflective of poverty and socioeconomic status. Three themes emerged from the interviews: (1) using contraception was described as a selfish decision by the mother without benefit to the newborn; (2) women felt pressure to breastfeed and saw the inability to breastfeed as a personal failure; and (3) medical providers were viewed as more trustworthy when it came to information regarding breastfeeding as opposed to contraceptive options, where decisions relied on anecdotes from friends or family. CONCLUSIONS: Most decision-making regarding breastfeeding and contraception relied on the personal experiences of the participants and their friends and family. A clear need for support for women who are unable to breastfeed and education about the benefits of contraception for the newborn was identified.

Attitudes and experiences with termination of pregnancy among Irish obstetrics & gynaecology trainees in the context of recent legal change: A survey study.

OBJECTIVE: This study examines Irish obstetrics and gynaecology trainees' experiences with and opinions of termination of pregnancy (ToP) after legal change. STUDY DESIGN: We invited obstetrics & gynaecology non-consultant hospital doctors (NCHDs) to participate in a web-based survey through a professional e-mail listserv. We conducted descriptive statistical analyses of responses using Stata SE Version 16. RESULTS: A total of 102/202 (50.5%) trainees responded to the survey. Of these, 61.8% believed that ToP should be allowed on request up to 12 weeks and in limited circumstances thereafter (in line with current law), and 19.6% believe ToP should be allowed on request even after 12 weeks. Knowledge about the abortion law was high (70.6% achieved a perfect knowledge score). Since the new law came into effect, 61.8% of trainees reported participation in abortion care, though only 25.5% had performed surgical procedures. More than 75% of respondents would like to receive more training in all clinical skills related to ToP. In the future, 67.6% of respondents would be willing to provide TOP in all circumstances allowed by law. CONCLUSION: Irish obstetrics & gynaecology NCHDs are generally supportive of the legislation. Few trainees have performed surgical abortions, and most would like to receive additional clinical training related to ToP.

Telemedicine for contraceptive counseling: Patient experiences during the early phase of the COVID-19 pandemic in New York City.

OBJECTIVE: During theCOVID-19 pandemic, many clinicians increased provision of telemedicine services. This study describes patient experiences with telemedicine for contraceptive counseling during the COVID-19 pandemic in New York City. STUDY DESIGN: This is a mixed-methods study which includes a web-based or phone survey and in-depth phone interviews with patients who had telemedicine visits for contraception. RESULTS: A total of 169 patients had eligible telemedicine visits between April 1 and June 30, 2020. Of these, 86 (51%) responded to the survey, and 23 (14%) participated in the interviews. We found that 86% of survey respondents were very satisfied with the telemedicine visit, and 63% said it completely met their needs. A majority (73%) strongly agreed that these visits should be maintained after the COVID-19 pandemic, and half (51%) would be very likely to choose them over in-person visits. In-depth interviews highlighted the convenience of telemedicine, especially for those with work or parenting responsibilities. Although some patients had in-person visits after telehealth, many appreciated the counseling they received remotely, and found the subsequent in-person visits more efficient. Patients identified visits that do not require physical exams as ideal visits for telehealth, and some hoped that all or most of their future visits would be telehealth visits. Many patients (43%) expressed a preference for phone over video visits. CONCLUSIONS: Patients reported an overall positive experience with telemedicine visits for contraceptive counseling during the COVID-19 pandemic. They appreciated the convenience of telemedicine visits and valued the virtual counseling experience. IMPLICATIONS: Health care providers who initiated or expanded telemedicine services for contraceptive counseling during the COVID-19 pandemic should consider continuing to offer them after the pandemic. At the policy level, these findings favor expanding access to telemedicine and providing reimbursement for virtual visits, including telephone visits.

Urban ecology of hosts and vectors of Rickettsia in a rickettsiosis-endemic city of the Yucatan peninsula, Mexico.

Rickettsioses are vector-borne zoonotic diseases that occur in urban environments. Currently, they are associated with the presence of domestic and synanthropic animals, the ectoparasites that they harbor, and their local habitat. The implementation of prevention actions relies on the understanding of the local ecology of interactions between hosts, vector species, and the etiologic agents. In this context, this study aimed to explore and describe the occurrence of infected mammals and their ectoparasites in human urban dwellings, and those characteristics of urban dwellings associated to the presence of Rickettsia infected animals in groups of households where at least one human case of rickettsiosis has occurred in the previous year of the study. Briefly, blood-samples and ectoparasites from synanthropic and domestic animals, were obtained from groups of households from different areas of an urban settlement. Serologic and molecular diagnostics helped to identify Spotted Fever Group (SFG) and TG (Typhus Group) Rickettsia in animal and ectoparasite samples. A total of 99 mammals were sampled, 29 opossums (Didelphis virginiana), 13 house mice (Mus musculus), seven black rats (Rattus rattus) and 50 dogs. Infection occurrence in opossums was 8.3% of SFG, 50% for TG, and 4.2% of undetermined group. For house mice 46.2% for SFG and 30.8% were undetermined. Black rats 28.6% of SFG and 57.1% undetermined. Finally, dogs were 19.1% of SFG, 57.4% to TG, and 23.4% belonged to undetermined group. A total of 424 ectoparasites were collected from the mammals. In opossums occurred the ticks Ambyomma sp., Ornithodoros (Alecterobius) nr. talaje, and the flea Ctenocephalides felis. In dogs we found the ticks Rhipicephalus sanguineus s. l., Amblyomma sp., O. (A.) nr. talaje, and the flea Ct. felis. No ectoparasites were collected from rodents. The occurrence of infected animals was associated primarily with the material of the backyard floor, the type of sanitary system in the household, the presence of garbage in the backyard, presence of firewood storage, stored polyethylene terephthalate (PET) containers for sale to recyclers, and the store of construction supplies in the backyard. Nonetheless a generalized linear model showed that the household with a backyard with a dirt floor or other non-concrete material has more chances of harboring infected animals (RR= 1.74, 95% CI= 1.07-2.84 and RR= 1.03, 95% CI= 0.39-2.32 respectively). In contrast, when the house has a sanitary system of urban sewer system or a latrine outside de house, the chances of having infected animals decreased significantly (RR= 0.39, 95% CI= 0.12-0.94 and RR= 0.46, 95% CI= 0.03-2.22). We conclude that both SFG and TG rickettsioses occur in animals and their ectoparasites in peridomiciles of urban households were at least one human rickettsiosis case had occurred.

Telemedicine for contraceptive counseling: An exploratory survey of US family planning providers following rapid adoption of services during the COVID-19 pandemic.

OBJECTIVE: During the COVID-19 pandemic, many clinicians started offering telemedicine services. The objective of this study is to describe the experience of US family planning providers with the rapid adoption of telemedicine for contraceptive counseling during this period. STUDY DESIGN: This is a cross-sectional web-based survey of family planning providers practicing in the United States. RESULTS: A total of 172 providers completed the survey (34% response rate). Of these, 156 (91%) provided telemedicine services in the 2 months preceding the survey. Most (78%) were new to telemedicine. About half (54%) referred less than a quarter of contraception patients for in-person visits, and 53% stated that the most common referral reason was long-acting reversible contraceptive (LARC) insertion. A majority of providers strongly agree that telemedicine visits are an effective way to provide contraceptive counseling (80%), and that this service should be expanded after the pandemic (84%). If asked to provide telemedicine visits after the pandemic, 64% of providers would be very happy about it. Many providers used personal phones or smartphones to conduct telemedicine visits but stated that ideal devices would be work-issued computers, tablets, or phones. More than half (59%) of providers prefer video over phone visits. CONCLUSIONS: Family planning clinicians in the United States reported a positive experience with telemedicine for contraceptive counseling during the early stage of the COVID-19 pandemic and believe that this service should be expanded. Clinicians seem to prefer using work-issued devices and conducting video rather than phone visits. IMPLICATIONS: Telemedicine is a promising option for providing contraceptive counseling even beyond the COVID-19 pandemic. An investment in hospital or clinic-issued devices that allow for video conferencing may optimize clinicians' telemedicine experience.

Characteristics and Outcomes of 241 Births to Women With Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) Infection at Five New York City Medical Centers.

OBJECTIVE: To describe the characteristics and birth outcomes of women with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection as community spread in New York City was detected in March 2020. METHODS: We performed a prospective cohort study of pregnant women with laboratory-confirmed SARS-CoV-2 infection who gave birth from March 13 to April 12, 2020, identified at five New York City medical centers. Demographic and clinical data from delivery hospitalization records were collected, and follow-up was completed on April 20, 2020. RESULTS: Among this cohort (241 women), using evolving criteria for testing, 61.4% of women were asymptomatic for coronavirus disease 2019 (COVID-19) at the time of admission. Throughout the delivery hospitalization, 26.5% of women met World Health Organization criteria for mild COVID-19, 26.1% for severe, and 5% for critical. Cesarean birth was the mode of delivery for 52.4% of women with severe and 91.7% with critical COVID-19. The singleton preterm birth rate was 14.6%. Admission to the intensive care unit was reported for 17 women (7.1%), and nine (3.7%) were intubated during their delivery hospitalization. There were no maternal deaths. Body mass index (BMI) 30 or higher was associated with COVID-19 severity (P=.001). Nearly all newborns tested negative for SARS-CoV-2 infection immediately after birth (97.5%). CONCLUSION: During the first month of the SARS-CoV-2 outbreak in New York City and with evolving testing criteria, most women with laboratory-confirmed infection admitted for delivery did not have symptoms of COVID-19. Almost one third of women who were asymptomatic on admission became symptomatic during their delivery hospitalization. Obesity was associated with COVID-19 severity. Disease severity was associated with higher rates of cesarean and preterm birth.

Clinical course of severe and critical coronavirus disease 2019 in hospitalized pregnancies: a United States cohort study.

Background: The coronavirus disease 2019 pandemic has had an impact on healthcare systems around the world with 3 million people contracting the disease and 208,000 cases resulting in death as of this writing. Information regarding coronavirus infection in pregnancy is still limited. Objective: This study aimed to describe the clinical course of severe and critical coronavirus disease 2019 in hospitalized pregnant women with positive laboratory testing for severe acute respiratory syndrome coronavirus 2. Study Design: This is a cohort study of pregnant women with severe or critical coronavirus disease 2019 hospitalized at 12 US institutions between March 5, 2020, and April 20, 2020. Severe disease was defined according to published criteria as patient-reported dyspnea, respiratory rate >30 per minute, blood oxygen saturation ≤93% on room air, ratio of partial pressure of arterial oxygen to the fraction of inspired oxygen <300 mm Hg, or lung infiltrates >50% within 24-48 hours on chest imaging. Critical disease was defined as respiratory failure, septic shock, or multiple organ dysfunction or failure. Women were excluded from the study if they had presumed coronavirus disease 2019, but laboratory testing was negative. The primary outcome was median duration from hospital admission to discharge. Secondary outcomes included need for supplemental oxygen, intubation, cardiomyopathy, cardiac arrest, death, and timing of delivery. The clinical courses are described by the median disease day on which these outcomes occurred after the onset of symptoms. Treatment and neonatal outcomes are also reported. Results: Of 64 hospitalized pregnant women with coronavirus disease 2019, 44 (69%) had severe disease, and 20 (31%) had critical disease. The following preexisting comorbidities were observed: 25% had a pulmonary condition, 17% had cardiac disease, and the mean body mass index was 34 kg/m2. Gestational age was at a mean of 29±6 weeks at symptom onset and a mean of 30±6 weeks at hospital admission, with a median disease day 7 since first symptoms. Most women (81%) were treated with hydroxychloroquine; 7% of women with severe disease and 65% of women with critical disease received remdesivir. All women with critical disease received either prophylactic or therapeutic anticoagulation during their admission. The median duration of hospital stay was 6 days (6 days [severe group] and 10.5 days [critical group]; P=.01). Intubation was usually performed around day 9 on patients who required it, and peak respiratory support for women with severe disease was performed on day 8. In women with critical disease, prone positioning was required in 20% of cases, the rate of acute respiratory distress syndrome was 70%, and reintubation was necessary in 20%. There was 1 case of maternal cardiac arrest, but there were no cases of cardiomyopathy or maternal death. Thirty-two of 64 (50%) women with coronavirus disease 2019 in this cohort delivered during their hospitalization (34% [severe group] and 85% [critical group]). Furthermore, 15 of 17 (88%) pregnant women with critical coronavirus disease 2019 delivered preterm during their disease course, with 16 of 17 (94%) pregnant women giving birth through cesarean delivery; overall, 15 of 20 (75%) women with critical disease delivered preterm. There were no stillbirths or neonatal deaths or cases of vertical transmission. Conclusion: In pregnant women with severe or critical coronavirus disease 2019, admission into the hospital typically occurred about 7 days after symptom onset, and the duration of hospitalization was 6 days (6 [severe group] vs 12 [critical group]). Women with critical disease had a high rate of acute respiratory distress syndrome, and there was 1 case of cardiac arrest, but there were no cases of cardiomyopathy or maternal mortality. Hospitalization of pregnant women with severe or critical coronavirus disease 2019 resulted in delivery during the clinical course of the disease in 50% of this cohort, usually in the third trimester. There were no perinatal deaths in this cohort.

Rickettsia spp. en garrapatas (Acari: Ixodidae) que infestan perros de una comunidad rural con antecedentes de rickettsiosis, Yucatán, México / Rickettsia spp. in ticks (Acari: Ixodidae) infesting dogs from a rural community with rickettsial diseases reports, Yucatan, Mexico

RESUMEN Introducción: Las bacterias del género Rickettsia son agentes causales de las rickettsiosis, enfermedades zoonóticas transmitidas por ectoparásitos. En Yucatán, ocurrió un brote en habitantes de Bolmay, Valladolid; sin embargo, no se identificó el probable artrópodo vector. Objetivo: Analizar la presencia de Rickettsia spp. en garrapatas que infestan perros domésticos de Bolmay. Material y métodos: Se trabajaron 105 viales con hasta ocho garrapatas. Se extrajo ADN de los ectoparásitos, posterior a la identificación del estadio de desarrollo vital, sexo, género y especie. Se realizaron dos PCR para aislar fragmentos de los genes htrA (17-kDa) y rOmpB, pertenecientes a Rickettsia spp. Los productos positivos fueron secuenciados y analizados con la herramienta BLAST y el algoritmo Megablast. Resultados: Se utilizaron 291 garrapatas de los géneros Amblyomma (55.7%, 162/291), Rhipicephalus (34%, 99/291) e Ixodes (10.3%, 30/291), y las especies Rhipicephalus sanguineus sensu lato, Ixodes affinis y Amblyomma mixtum. La positividad por PCR fue de 11.4% (12/105) para los géneros Amblyomma (66.7%, 8/12), Rhipicephalus (25%, 3/12) e Ixodes (8.3%, 1/12), y las especies A. mixtum, Rh. sanguineus s. l. e I. affinis. Se identificó ADN rickettsial en ninfas, larvas, adultos, machos y hembras. Cada análisis BLAST arrojó un 96% de cobertura e identidad con varias secuencias de Rickettsia spp. como Rickettsia typhi, Rickettsia felis y Rickettsia prowazekii, por lo que no fue posible determinar la especie infectante. Conclusión: Las garrapatas que infestan perros de Bolmay, probablemente están involucrados en el ciclo de transmisión de Rickettsia spp. Se presenta la primera evidencia molecular de Rickettsia spp. en garrapatas I. affinis de Yucatán, México.

ABSTRACT Introduction: Bacteria of the Rickettsia genus are causal agents of the rickettsial diseases, zoonoses transmitted by ectoparasites. In Yucatan, in inhabitants from Bolmay an outbreak occurred; however, the probable vector was not identified. Objective: To analyze the Rickettsia spp. presence in ticks infesting domestic dogs from Bolmay. Material and methods: We used 105 vials with up to eight ticks. Total DNA from the ectoparasites was extracted, after the identification of the life stages, sex, gender, and species. Two PCR to isolate fragments of the htrA (17-kDa) and rOmpB genes belonging to Rickettsia spp., were performed. The positive products were sequenced and analyzed using the BLAST tool and the Megablast algorithm. Results: 291 ticks of the genera Amblyomma (55.7%, 162/291), Rhipicephalus (34%, 99/291), and Ixodes (10.3%, 30/291), and the species Rhipicephalus sanguineus sensu lato, Ixodes affinis, and Amblyomma mixtum, were used. The PCR positivity was 11.4% (12/105) for the genera Amblyomma (66.7%, 8/12), Rhipicephalus (25%, 3/12), and Ixodes (8.3%, 1/12), and the species A. mixtum, Rh. sanguineus s. l., and I. affinis. Rickettsial DNA in nymph, larva, adult, males, and females, were identified. Each BLAST analysis showed an identity and coverage of 96% with several Rickettsia spp. sequences, such as Rickettsia typhi, Rickettsia felis and Rickettsia prowazekii, so it was not possible to determine the infecting species. Conclusion: Ticks infesting dogs from Bolmay are probably involved in the transmission cycle of Rickettsia spp. The first molecular evidence of Rickettsia spp. in I. affinis ticks from Yucatan, Mexico, is presented.
