Abstract
Associated with gastritis, peptic-ulcer disease, and gastric carcinoma, Helicobacter pylori (H. pylori) also has been associated with decreased cognitive function and dementia. In this study, we used data from the UK Biobank to further examine associations between H. pylori seropositivity and serointensity and performance on several cognitive tasks in adults 40 to 70 years of age (M = 55.3, SD = 8.1). In these analyses, H. pylori seropositivity (i.e., either positive or negative for H. pylori) and serointensity (concentration of antibodies against H. pylori antigens) in adjusted models were associated with worse function on tasks of Numeric memory, Reasoning, and errors on the Pairs matching test but better function on the Tower rearrangement task. Together, these findings suggest that H. pylori seropositivity and serointensity might be associated with worse cognitive function in this age group.

Abstract
Infektionen sind eine wichtige potenzielle Gefahrenquelle für Schwangere und ihre ungeborenen Kinder. Schwangere und Frauen mit Kinderwunsch sollten sich daher fachkundig darüber beraten lassen, welche Impfungen vor bzw. während einer Schwangerschaft sinnvoll sind. Zur Impfberatung gehören auch Fragestellungen zu Reiseimpfungen, insbesondere wenn das Reiseziel in einem Endemiegebiet für Erkrankungen wie Malaria, Gelbfieber, Tuberkulose, Hepatitis, Human-immunodeficiency-virus-assoziierte Erkrankungen, Leishmaniose, Toxoplasmose und Japanische Enzephalitis liegt. Grundsätzlich können alle Toxoidimpfstoffe, inaktivierten Impfstoffe und Immunglobuline in der Schwangerschaft verabreicht werden, Lebendimpfstoffe sind kontraindiziert. Empfehlenswerte Impfungen in der Schwangerschaft sind Tetanus, Diphtherie, Pertussis im Falle eines fehlenden Impfschutzes, die saisonale Influenzaimpfung und aktuell die Coronavirus-disease-19(COVID-19)-Impfung ab dem zweiten Trimenon. Zu den empfohlenen Reiseschutzimpfungen zählen alle Standardimpfungen, das heißt die Grundimmunisierung gegen Rotaviren, Tetanus, Diphtherie, Pertussis, Haemophilus influenzae Typ B, Poliomyelitis, Hepatitis B, Pneumokokken, Meningokokken, Masern, Mumps, Röteln, Varizellen, humanes Papillomavirus und Influenza. Darüber hinaus hat in der Reisemedizin der Immunschutz gegen Hepatitis A einen hohen Stellenwert. Nach den internationalen Gesundheitsempfehlungen der World Health Organization ist zur Einreise in bzw. Ausreise aus bestimmten Ländern eine zusätzliche spezifische Impfvorschrift für die Gelbfieber- und Poliomyelitisimpfung vorgesehen. Einzelne Länder haben darüber hinaus zusätzliche Impfvorschriften für die Ein- und Ausreise. „Indikationsimpfungen“ setzen ein entsprechendes lokales Risiko voraus.

Abstract
BACKGROUND Maternal infections during pregnancy, particularly with rubella virus, were reported to increase the risk of diabetes in children. Widespread vaccination has decreased the number of infants with congenital rubella syndrome in the United States, although it remains a problem in developing countries. Because vaccine hesitancy has recently increased, we investigated the association between congenital infections with subsequent diabetes risk in children in the United States. METHODS Using data from a nationwide private health insurer for years 2001-2017, 1 475 587 infants were followed for an average of 3.9 years (maximum 16.5 years). Information was obtained regarding congenital infections (rubella, cytomegalovirus, other congenital infections) and perinatal infections, as well as for the development of diabetes mellitus and diabetic ketoacidosis. RESULTS There were 781 infants with congenital infections and 73 974 with perinatal infections. Diabetes developed in 3334 children. The odds of developing diabetes for infants with congenital rubella infection were 12-fold greater (P = .013) and, for infants with congenital cytomegalovirus infection, were 4-fold greater (P = .011) than infants without congenital or perinatal infection. Infants with other congenital infections had 3-fold greater odds of developing diabetes (P = .044). Results were similar for diabetes ketoacidosis. Infants with other perinatal infections had 49% greater odds of developing diabetes during the follow-up period (P < .001). CONCLUSION Congenital and other perinatal infections are associated with elevated risks of developing diabetes mellitus during childhood. Vaccination for rubella remains an important preventive action to reduce the incidence of diabetes in children.

Abstract
Background Congenital cytomegalovirus (cCMV) infection is the most prevalent congenital infection acquired worldwide, with higher incidence in developing countries and among HIV-exposed children. Less is known regarding vertical transmission of parvovirus B19 (B19V) and enterovirus (EV). We aimed to assess the prevalence of CMV, B19V and EV vertical transmission and compare results of screening of congenital CMV obtained from two different specimens in a semirural Mozambican maternity. Methods A cross sectional study was conducted among pregnant mothers attending Manhiça District Hospital upon delivery. Information on maternal risk factors was ascertained. Dried umbilical cord (DUC) samples were collected in filter paper for CMV, B19V and EV detection by real-time polymerase chain reaction (RT-PCR), and nasopharyngeal aspirates (NPA) to test for CMV by RT-PCR. Maternal blood samples and placental biopsy samples were also obtained to investigate CMV maternal serology, HIV status and immunopathology. Results From September 2014 to January 2015, 118 mothers/newborn pairs were recruited. Prevalence of maternal HIV infection was 31.4% (37/118). CMV RT-PCR was positive in 3/115 (2.6%) of DUC samples and in 3/96 (6.3%) of NPA samples obtained from neonates. The concordance of the RT-PCR assay through DUC with their correspondent NPA sample was moderate (Kappa = 0.42 and p<0.001. No differences on cCMV prevalence were found among HIV-exposed and unexposed. All (100%) mothers were seropositive for CMV IgG. RT-PCR of EV and B19V in DUC were both negative in all screened cases. No histological specific findings were found in placental tissues. No risk factors associated to vertical transmission of these viral infections were found. Conclusions This study indicates the significant occurrence of vertical transmission of CMV in southern Mozambique. Larger studies are needed to evaluate the true burden, clinical relevance and consequences of congenital infections with such pathogens in resource-constrained settings.

Abstract
Infectious diseases acquired during travel pose a significant health risk to pregnant travellers, who are more susceptible to both acquiring certain infections and developing severe complications. A review of the literature focusing on recent evidence-based guidelines was conducted with attention to tropical infections in the pregnant patient. A summary meant to serve as a succinct reference for health care professionals caring for pregnant women is presented. Magnitude of risk, clinical features, management, and preventive strategies of major travel-acquired infections of pertinence to the pregnant traveller are summarized, including malaria, arboviral infections, foodborne infections, helminthic infections, and influenza. Tables with details on specific infections within each group and guidance for reducing travel-related health risks in the pregnant patient are presented.

Abstract
Importance Travel among US citizens is becoming increasingly common, and travel during pregnancy is also speculated to be increasingly common. During pregnancy, the obstetric provider may be the first or only clinician approached with questions regarding travel. Objective In this review, we discuss the reasons women travel during pregnancy, medical considerations for long-haul air travel, destination-specific medical complications, and precautions for pregnant women to take both before travel and while abroad. To improve the quality of pretravel counseling for patients before or during pregnancy, we have created 2 tools: a guide for assessing the pregnant patient's risk during travel and a pretravel checklist for the obstetric provider. Evidence Acquisition A PubMed search for English-language publications about travel during pregnancy was performed using the search terms "travel" and "pregnancy" and was limited to those published since the year 2000. Studies on subtopics were not limited by year of publication. Results Eight review articles were identified. Three additional studies that analyzed data from travel clinics were found, and 2 studies reported on the frequency of international travel during pregnancy. Additional publications addressed air travel during pregnancy (10 reviews, 16 studies), high-altitude travel during pregnancy (5 reviews, 5 studies), and destination-specific illnesses in pregnant travelers. Conclusions and Relevance Travel during pregnancy including international travel is common. Pregnant travelers have unique travel-related and destination-specific risks. We review those risks and provide tools for obstetric providers to use in counseling pregnant travelers.

Abstract
PURPOSE OF REVIEW Zika virus (ZIKV) is a mosquito-borne flavivirus that has caused a sudden and explosive outbreak in South America and the Caribbean in the last year, and has been declared a public health emergency by the WHO. As ZIKV afflicts previously naive populations, more severe clinical presentations and sequelae have been observed. A specific emphasis has been placed on the neurological effects in infants resulting from viral exposure in utero. RECENT FINDINGS Acute onset of ZIKV disease is seen in approximately 20% of cases, whereas most individuals (80%) exposed are asymptomatic. Presentation of illness is typically mild, with disease spectrum ranging from arthralgia and rash to encephalitis, myelitis, and Guillain-Barré syndrome. Infants have been uniquely impacted by the current outbreak with significant congenital exposure resulting in permanent neurological defects and developmental complications. SUMMARY The current ZIKV outbreak has illustrated the emergent capabilities of mosquito-borne viruses and the teratogenic nature of ZIKV. Causality and risk factors associated with severe manifestations, as well as chronic sequelae, have yet to be determined. Extensive research is required to understand the molecular mechanisms of infection, develop improved assays for differential diagnosis, and improve overall knowledge of the spectrum of ZIKV disease in order to develop modes of prevention and treatment.

Abstract
BACKGROUND Helicobacter pylori (H. pylori) infection is associated with cognitive deficits in humans, an association potentially mediated or moderated by folate concentration or inflammation. MATERIALS AND METHODS We used the National Health and Nutrition Examination Survey (NHANES) datasets to examine whether folate concentration or inflammation mediates or moderates the relationship between H. pylori and cognitive function. Models were performed using linear, Poisson, and zero-inflated Poisson regression, and we performed separate analyses for groups aged 20-59 and 60-90 years with sample sizes ranging from 700 to 1700. RESULTS We did not find evidence of mediation in either age group. In the 20- to 59-year group, interactions between H. pylori and ferritin (p values ranging from .004 to .039) were associated with worse processing speed, better working memory, and worse reaction time. Interactions between H. pylori and fibrinogen (p values ranging from .023 to .045), C-reactive protein (CRP) (p = .023), and the inflammatory index (p = .045) were associated with worse processing speed. In 60- to 90-year-olds, H. pylori interacted with ferritin and the inflammatory index to predict fewer mathematical errors (p values of .036 and .023). Interactions with folate (p values of .016 and .006) and C-reactive protein (p values ranging from <.001 to .048) were inconsistent in directionality. CONCLUSIONS In this dataset, representative of the US population, inflammation and folate concentrations moderated but did not mediate the association between H. pylori seropositivity and cognition.

Abstract
We analyzed risk factors for Leptospira seropositivity in humans, using data from a population-based cross-sectional zoonosis survey in South Germany (2008/9). Out of 1007 participants 42 (4.2 %) were sero-positive (19/446 men; 23/561 women), indicating that Leptospira exposure and sero-conversion is much more frequent than commonly assumed. Relative risks (RR) for seropositivity with exact 95 % confidence intervals (CI; adjusted for specificity and sensitivity of the ELISA test) were calculated for various exposure factors. Contact with pet rats (RR = 13.9 CI [4.8; 25.3]), guinea pigs (3.0[1.1; 7.4]), cattle (3.7[1.3; 9.6]), poultry (3.6[1.3; 8.6]) or livestock (2.3[1.1; 4.9]) as well as occupation as forestry worker (9.2[2.6; 21.4]) were identified as important exposure factors. None of the participants has ever been diagnosed with leptospirosis, yet 45 had experienced symptoms which may have been caused by Leptospira infection (12 with scleral icterus, 25 dark urine, 8 liver inflammation, 7 kidney failure). Three times as many participants with prior symptoms were seropositive as participants without symptoms (RR = 3.4[1.3; 8.3]), suggesting that sero-positive patients with severe symptoms may frequently not be diagnosed as leptospirosis cases. Physicians should consider leptospirosis as a differential diagnosis. Currently, the vast majority of symptomatic leptospirosis patients may neither be diagnosed nor reported.

Abstract
Pregnancy is a physiological situation that requires specific and careful preparation before travel. Malaria, dengue fever and viral hepatitis E are more severe in pregnancy and at higher risk of adverse obstetrical outcome. Medical and obstetrical contra-indications to travel should be listed during pre-travel evaluation. Vaccine indications are the same as in the general population, and must be discussed after a rigorous benefit-risk analysis. Pregnant women should avoid or delay travel in areas of high malarial chloroquino-resistance.

Abstract
Travel abroad for business and pleasure should be safe and meaningful for the traveler. To assure that safe experience, certain processes should be considered before travel. A thorough pretravel health assessment will offer patients and health care providers valuable information for anticipatory guidance before travel. The destination-based risk assessment will help determine the risks involved in travel to specific locations and guide in the development of contingency plans for all travelers, especially those with chronic conditions. Diseases are more prevalent overseas, and immunizations and vaccinations are all important considerations for persons traveling abroad.

Abstract
BACKGROUND The issue of travel to developing countries during pregnancy has not been sufficiently studied. The aim of this study is to investigate the rate, course, and outcome of pregnancies in women who traveled to developing countries while pregnant, or became pregnant during such travel. METHODS Women visiting two major travel clinics in Israel for consultation within the years 2004 to 2009, who were pregnant or declared an intention of becoming pregnant during travel were contacted. This was followed by a telephone interview by an obstetrician with those women who were actually pregnant. Background characteristics, morbidity during travel, and pregnancy course and outcome were collected. RESULTS Overall 52,430 travelers' records had been screened. Of these, we identified 49 women who were pregnant during their trip, but 3 declined participation. Of the remaining 46 women, 33 were pregnant at departure, and 13 conceived during travel. The incidence of pregnancy during travel was thus 0.93/1000 travelers. Thirty-three women traveled to East Asia, 8 to South and Central America, 5 to Africa. More than two thirds of women received pretravel vaccinations. Adherence to the World Health Organization recommendations regarding food and drink was high (87%) and travelers' diarrhea occurred in only 11% of women. Five of 22 women traveling to malarious areas had taken antimalarial prophylaxis. Six women required medical therapy during travel. Pregnancy outcome was not different from the normal population except for an unusually low rate of preterm delivery. CONCLUSIONS In this cohort, travel to developing countries was not associated with adverse pregnancy outcome. Larger studies are needed to support these findings.

Abstract
Fevers of unknown origin have been classified as classic, nosocomial, immune-deficient, and HIV-related. More than half of the 1407 human pathogens are zoonotic, making zoonotic infections an important subcategory in each of the classifications. This article describes both common and unusual zoonoses causing fevers of unknown origin. Simian immune virus is considered as a possible emerging infection. For special populations (the homeless, zoophiliacs, those whose occupation or leisure brings them in close contact with oceans or lakes, and veterinarians), zoonotic infection potentials are discussed.
