This study was the first time to perform the transcriptome sequences of the ovary of partially engorged and fully engorged H. flava. The results can benefit the understanding of the molecular basis of ovary maturation and oogenesis of the H. flava and boost the development of the strategies for control of H. flava.We investigated here, the prevalence of Nosema microsporidia infections in the honeybees, Apis cerana japonica and Apis mellifera, in the Tohoku region of Japan. We detected Nosema ceranae DNA in 14 (2.8%) of 509 A. cerana japonica and in 34 (21.9%) of 155 A. mellifera honeybees from Aomori, Iwate, Akita, Yamagata, and Fukushima prefectures. Nosema apis DNA was undetectable in A. cerana japonica and A. mellifera. The unidentifiable Nosema species that genetically differed from N. apis, N. ceranae, and N. neumanni in terms of small subunit (SSU) rDNA, large subunit rDNA, and internal transcribed spacer sequences was identified in 105 (20.6%) of 509 A. cerana japonica and in 1 (0.6%) of 155 A. mellifera honeybees, and from Iwate prefecture. A phylogenetic tree based on SSU rDNA sequences showed that the Nosema sp. belonged to the same clade as N. thomsoni detected in moth and solitary bees in North America and N. pieriae found in cabbage butterfly in Turkey, which have not hitherto been detected in honeybees. The morphological characteristics of the spores should be analyzed to enable species identification of the Nosema sp.

Researchers are interested in studying longitudinal patterns of gestational weight gain, yet this requires daily/weekly weights, and maternal weight is measured only during prenatal visits. We evaluated the relative accuracy and precision of methods for estimating maternal weight gain between prenatal visits among twin and singleton pregnancies.

We analyzed cohorts of dichorionic twin and singleton pregnancies delivered from 1998-2013 in Pittsburgh, Pennsylvania. We mimicked a typical study by retaining pre-pregnancy, first prenatal visit, glucose screening visit, and delivery weights, using these to fit interpolation models, estimating weight throughout pregnancy using 16 different methods, and calculating the difference in kilograms between predicted and measured values among remaining weights. We evaluated the performance of each model by calculating root mean squared error (RMSE).

RMSE ranged from 1.55 to 6.09kg in twins (n=2067) and 1.45 to 4.87kg in singletons (n=7331). selleck chemical The most accurate and precise methods incorporated restricted cubic splines, random intercepts and slopes for pregnancy, and internal knots demarcating trimesters/quantiles (RMSE=1.55/1.56kg in twins, 1.45/1.45kg in singletons), while individual-level linear interpolation between proximal measurements also performed well.

Accuracy and precision of methods for estimating maternal weight gain between measurements differed by model, and were best among individually-tailored and flexible models.

This study aimed to describe substance use (SU) among adolescents and young adults (AYA) with chronic kidney disease, compare these findings with the general population, and identify associated risk factors.

708 AYA participants contributing 2475 person-visits from the Chronic Kidney Disease in Children Study were used to estimate prevalence rates of past year and 30-day alcohol, cigarette, e-cigarette and marijuana use, and were compared with national surveys. Repeated measures logistic regression estimated the association between SU and participant characteristics.

There was nearly no SU among those 12 to 14 years, but use increased with age, and past year alcohol use was about 80% for those greater than or equal to 22 years. Rates of use among males were constant or increased with age, while rates of use among females were lower after age 22 compared to ages 18 to 22. Associated risk factors included non-Black and non-Hispanic identity, older age, and worse disease severity. Participants were less likely to use substances compared to the general population, especially those 14-18 years.

SU was less common in AYA with chronic kidney disease than the general population, but differences were attenuated among those greater than or equal to 18 years. Ages 12-14 appear to be the ideal time for prevention efforts. As the landscape of e-cigarette and marijuana policies change, these results underscore the need to understand how similar high-risk populations engage in SU.

There is a growing concern about the COVID-19 epidemic intensifying in rural areas in the United States (U.S.). In this study, we described the dynamics of COVID-19 cases and deaths in rural and urban counties in the U.S.

Using data from April 1 to November 12, 2020, from Johns Hopkins University, we estimated COVID-19 incidence and mortality rates and conducted comparisons between urban and rural areas in three time periods at the national level, and in states with higher and lower COVID-19 incidence rates.

Results at the national level showed greater COVID-19 incidence rates in urban compared to rural counties in the Northeast and Mid-Atlantic regions of the U.S. at the beginning of the epidemic. However, the intensity of the epidemic has shifted to a rapid surge in rural areas. In particular, high incidence states located in the Mid-west of the country had more than 3,400 COVID-19 cases per 100,000 people compared to 1,284 cases per 100,000 people in urban counties nationwide during the third period (August 30 to November 12).

Overall, the current epicenter of the epidemic is located in states with higher infection rates and mortality in rural areas. Infection prevention and control efforts including healthcare capacity should be scaled up in these vulnerable rural areas.
