Background In-hospital mortality and discharge disposition following traumatic hip fractures previously reported in the literature, has mainly focused on a nationwide scale, which may not be reflective of unique populations. Objective Our aim was to characterize demographics, hospital disposition, and associated outcomes for patients with the most common hip fractures. Methods A retrospective study utilizing the Trauma Registry from the Texas Department of State Health Services. Patient demographics, injury characteristics, and outcomes, such as in-hospital mortality, and discharge dispositions, were collected. The data were analyzed via univariate analysis and multivariate regressions. Results There were 17,104 included patients, composed of 45% femoral neck fractures (FN) and 55% intertrochanteric fractures (IT). There were no differences in injury severity score (ISS) (9 ± 1.8) or age (77.4 ± 8 years old) between fracture types. In-hospital mortality risk was low but different among fracture types (intertrochanteric, 1.9% vs femoral neck, 1.3%, P = .004). However, when controlling for age, and ISS, intertrochanteric fractures and Hispanic patients were associated with higher mortality ( P < .001, OR 1.5, 95% CI 1.1-2.0). Uninsured, and Black/African American ( P = .05, OR 1.2, 95% CI 1.1-1.3) and Hispanic ( P < .001, OR 1.2, 95% CI 1.1-1.3) patients were more likely to be discharged home after adjusting for age, ISS, and payment method. Conclusion Regardless of age, severity of the injury or admission hemodynamics, intertrochanteric fractures and Hispanic/Latino patients had an increased risk of in-hospital mortality. Patients who were uninsured, Hispanic, or Black were discharged home rather than to rehabilitation, regardless of age, ISS, or payment method.

AbstractDynamic mechanical analysis (DMA) measurements of water-saturated earlywood (EW) and latewood (LW) of various wood species in the temperature range from 0 to 100 °C were focused to clarify the differences in thermal softening properties within an annual ring. The following results were obtained. The peak of tanδ caused by micro-Brownian motion of lignin was observed in both EW and LW all species. For softwoods, the peak temperatures of tanδ of EW appeared at higher temperatures than those of LW. For hardwoods, in the other hand, the peak temperatures of tanδ were slightly different between EW and LW in the diffuse-porous wood, whereas the temperatures were almost the same in the ring-porous wood. It was found that the difference in peak temperature of tanδ between EW and LW varied greatly among species. The difference in peak temperature between EW and LW was relatively large for softwoods. In addition, the thermal softening properties both in the radial and tangential directions differed depending on the species, so this suggested that there was anisotropy in the thermal softening properties depending on the species.

Abstract
Background
Coffee is one of the most consumed beverages in the world, coffee consumption has been growing in the United States over the past 20 years. Periodontitis is defined by the pathologic loss of the periodontal ligament and destruction of the connective tissue attachment and alveolar bone loss and is related to different systemic diseases and conditions. However, the causality has remained unclarified, thus we regarded discovering the causal relationship between coffee consumption and the liability to periodontitis as the objective of the study.

Methods
Coffee consumption was subdivided into binary coffee consumption and continuous coffee consumption to refine the study design. Genetic instruments were stretched from the MRC-IEU’s (MRC Integrative Epidemiology Unit) output from the GWAS pipeline using phesant-derived variables based on the UK Biobank, the Gene-Lifestyle Interactions in Dental Endpoints (GLIDE) project, and the joint meta-analysis of a recent GWAS. The IVW (Inverse Variance Weighted) was regarded as the primary method to estimate the causality, a scatter plot revealed the intuitive result, and tests for stability were also carried out.

Results
An effect of continuous coffee consumption on the risk of periodontitis was found, with per SD of coffee consumed increases, the risk of periodontitis rises by 1.04% (Odds Ratio of IVW is 1.0104), while the effect of binary coffee consumption on periodontitis did not meet the requirement of indicating a strong causal association, neither were the reverse causality analyses.

Conclusions
The study indicated the causality of continuous coffee consumption to the risk of periodontitis with a relatively small scale of effect estimate and no strong evidence for an effect of binary coffee-consuming behavior on periodontitis. There was also no intensive evidence suggesting reverse causality.

Abstract
Background
. Lack of exposure to the natural microbial diversity of the environment has been linked to dysregulation of the immune system and numerous noncommunicable diseases, such as allergies and autoimmune disorders. Our previous studies suggest that contact with soil material, rich in naturally occurring microbes, could have a beneficial immunoregulatory impact on the immune system in mice and humans. However, differences in the immunomodulatory properties of autoclaved, sterile soil material and non-autoclaved, live soil material have not been compared earlier.

Results
. In this study, we exposed C57BL/6 mice to autoclaved and live soil powders that had the same rich microbiota before autoclaving. We studied the effect of the soil powders on the mouse immune system by analyzing different immune cell populations, gene expression in the gut, mesenteric lymph nodes and lung, and serum cytokines. Both autoclaved and live soil exposure were associated with changes in the immune system. The exposure to autoclaved soil resulted in higher levels of Rorγt, Inos and Foxp3 expression in the colon. The exposure to live soil was associated with elevated IFN-γ concentration in the serum. In the mesenteric lymph node, exposure to live soil reduced Gata3 and Foxp3 expression, increased the percentage of CD8 + T cells and the expression of activation marker CD80 in XCR1+SIRPα− migratory conventional dendritic cell 1 subset.

Conclusions
. Our results indicate that exposure to the live and autoclaved soil powders is not toxic for mice. Exposure to live soil powder slightly skews the immune system towards type 1 direction which might be beneficial for inhibiting type 2-related inflammation. Further studies are warranted to quantify the impact of this exposure in experimental type 2 inflammation.

Published: September 2023

Abstract
Background
Mycorrhiza is a ubiquitous form of symbiosis based on the mutual, beneficial exchange of resources between roots of autotrophic (AT) plants and heterotrophic soil fungi throughout a complex network of fungal mycelium. Mycoheterotrophic (MH) and mixotrophic (MX) plants can parasitise this system, gaining all or some (respectively) required nutrients without known reciprocity to the fungus. We applied, for the first time, an ecological stoichiometry framework to test whether trophic mode of plants influences their elemental carbon (C), nitrogen (N), and phosphorus (P) composition and may provide clues about their biology and evolution within the framework of mycorrhizal network functioning.

Results
We analysed C:N:P stoichiometry of 24 temperate orchid species and P concentration of 135 species from 45 plant families sampled throughout temperate and intertropical zones representing the three trophic modes (AT, MX and MH). Welch’s one-way ANOVA and PERMANOVA were used to compare mean nutrient values and their proportions among trophic modes, phylogeny, and climate zones. Nutrient concentration and stoichiometry significantly differentiate trophic modes in orchids. Mean foliar C:N:P stoichiometry showed a gradual increase of N and P concentration and a decrease of C: nutrients ratio along the trophic gradient AT < MX < MH, with surprisingly high P requirements of MH orchids. Although P concentration in orchids showed the trophy-dependent pattern regardless of climatic zone, P concentration was not a universal indicator of trophic modes, as shown by ericaceous MH and MX plants.

Conclusion
The results imply that there are different evolutionary pathways of adaptation to mycoheterotrophic nutrient acquisition, and that the high nutrient requirements of MH orchids compared to MH plants from other families may represent a higher cost to the fungal partner and consequently lead to the high fungal specificity observed in MH orchids.

Abstract
Background
Pregnant women have an increased risk of getting infected with SARS-CoV-2 and are more prone to severe illness. Data on foetal demise in affected pregnancies and its underlying aetiology is scarce and pathomechanisms remain largely unclear.

Case
Herein we present the case of a pregnant woman with COVID-19 and intrauterine foetal demise. She had no previous obstetric or gynaecological history, and presented with mild symptoms at 34 + 3 weeks and no signs of foetal distress. At 35 + 6 weeks intrauterine foetal death was diagnosed. In the placental histopathology evaluation, we found inter- and perivillous fibrin depositions including viral particles in areas of degraded placental anatomy without presence of viral entry receptors and SARS-CoV-2 infection of the placenta.

Conclusion
This case demonstrates that maternal SARS-CoV-2 infection in the third trimester may lead to an unfavourable outcome for the foetus due to placental fibrin deposition in maternal COVID-19 disease possibly via a thrombogenic microenvironment, even when the foetus itself is not infected.

Abstract
Background
A new type of viral pneumonia, which has been named Coronavirus disease (COVID-19) began in Wuhan, China in late 2019 and has spread across the world since then. It has claimed more than 370 million confirmed cases and over 5.6 million deaths have been reported globally by the end of January 2022. This study aimed to analyze the trends, highly-nuanced patterns, and related key results relative to COVID-19 epidemiology in Sri Lanka.

Methods
Data on COVID-19 from March 2020 to January 2022 were obtained from published databases maintained by the Epidemiology Unit of the Ministry of Health in Sri Lanka and information regarding populations in administrative districts was obtained from the Department of Census and Statistics, Sri Lanka. Descriptive spatiotemporal analysis and autocorrelations were analyzed using SPSS statistical software.

Results
In Sri Lanka, the first case of COVID-19 was a Chinese national and the first local case was identified in the second week of March. As of 31st of January 2022, a total of 610,103 COVID-19 cases had been recorded in the country, and 15,420 patients had died. At the beginning, the disease was mainly concentrated in the Western province and with time, it spread to other provinces. However, very low numbers of patients were identified in the North, Eastern, North Central, and Uva provinces until April 2021. The peak of COVID-19 occurred in August and September 2021 in all provinces in Sri Lanka. Then a decreasing trend of COVID-19 cases showed after September 2021.

Conclusions
COVID-19 is an emerging public health problem in Western and Southern Sri Lanka where the population density is high. A decreasing trend of COVID-19 cases showed in all provinces after September 2021. Public awareness programs for the prevention and control of the disease in endemic regions are essential to reduce the incidence of this infection.

Published: September 2023

Abstract
Background
A non-negligible proportion of children grow up with problematic alcohol use in the family. Problematic familial drinking can be regarded as a stressor, and prior studies have consistently reported poorer mental health among adolescents who are exposed. However, it is also of relevance to identify modifiable protective factors which may buffer against stress-related ill-health in this group of adolescents. One context where such factors may be present is the school. The aim of this study is to examine the relationship between perceived problematic familial alcohol use and students’ stress-related complaints, and specifically to explore if the school’s degree of student focus can buffer against any such negative health consequences of problem drinking at home.

Methods
Data were drawn from four separate surveys, the Stockholm School Survey (SSS) and the Stockholm Teacher Survey (STS) conducted in 2014 and 2016 among 7,944 students (~ 15–16 years) and 2,024 teachers in 147 Stockholm senior-level school units. Perceived problematic familial alcohol use was measured by one item in the SSS. Stress-related complaints were captured by co-occurring somatic complaints and psychological distress, and reported by students in the SSS. The school’s student focus was measured by an index based on teachers’ ratings of four items in the STS. A set of covariates at the student and the school level were also included. Two-level binary logistic and linear regression models were performed.

Results
Perceived problematic familial alcohol use was linked with an increased likelihood of reporting co-occurring somatic complaints as well as psychological distress. Cross-level interactions revealed that the association between perceived problematic familial alcohol use and co-occurring somatic complaints was weaker among students attending schools with stronger teacher-rated student focus. Regarding psychological distress, the association was weaker for students attending schools with intermediate or strong teacher-rated student focus, compared with those attending schools with weaker teacher-rated student focus.

Conclusions
The findings provide support for the assumption that favourable conditions in schools can buffer against negative health consequences of problematic conditions in the family, thus serving a compensatory role.
The influence of bystander presence on evaluations of public breastfeeding among adults in the United States
Authors: Houlihan Amy E. , Zaikman Yuliana , Alford Allison M. 
Published: September 2023

Abstract
Background
In general, people tend to support private breastfeeding more than public breastfeeding, and discomfort surrounding public breastfeeding may contribute to sub-optimal rates of breastfeeding in the United States. Few studies have systematically examined situational factors that contribute to (negative) reactions to public breastfeeding. It is unclear whether the physical location or the presence of others is more influential in shaping people’s evaluations of public breastfeeding. This study aimed to experimentally investigate the influence of location, bystander presence, bystander gender, and the breastfeeding woman’s use of a cover on people’s evaluations of breastfeeding images.

Method
A sample of adults residing in the United States was randomly assigned to view an image of a breastfeeding woman in an experimental study that examined four independent variables: breastfeeding location (public vs. private), bystander presence (present vs. not present), gender of bystander (male vs. female), and use of a cover (cover vs. no cover). Participants then reported their emotional reactions to, perceptions of, and behavioral intentions toward the breastfeeding woman. In addition, participants completed measures of sexism, traditional gender role endorsement, sexual comfort, body gaze, and breastfeeding knowledge and experience.

Results
Hierarchical regressions revealed no differences between private and public breastfeeding images. Perceptions of the breastfeeding woman were more favorable when she was alone than with others, and when she was covered than when she was not covered. Evaluations tended to be more favorable among participants who scored lower on hostile sexism, higher on benevolent sexism, higher on sexual comfort, and higher on breastfeeding knowledge.

Conclusion
The presence of bystanders may be more consequential than the physical location in shaping reactions to public breastfeeding. These findings can be applied to improve support for public breastfeeding, which may contribute to higher breastfeeding rates and the associated public health benefits.

Published: September 2023

Abstract
Purpose
Rotator Cuff (RC) lesions are classified in full-thickness and partial-thickness tears (PTRCTs). To our knowledge, no studies investigated the mean size of shoulder tendons in healthy and PTRCT patients using MRI scans. The aim of the study was to provide data to obtain and compare the mean value of tendon sizes in healthy and PTRCTs groups.

Methods
From 2014 to 2020, 500 were included in the study. They were divided into two groups: Group 1 (100 subjects) was composed of people positive for partial-thickness rotator cuff tears (PTRCTs), while the 400 subjects in Group 2 were negative for PTRCTs.

Results
Overall, of the patients included in the study, 231 were females and 269 were males. The mean age of the patients was 49 ± 12.7 years. The mean thickness of the supraspinatus tendon (SSP) was 5.7 ± 0.6 mm in Group 1, 5.9 ± 0.6 mm in Group 2 (p < 0.001). The mean length of the ISP tendon was 27.4 ± 3.2 mm in Group 1, 28.3 ± 3.8 mm in Group 2 (p = 0.004). The mean width of the SSP tendon was 17 ± 1.6 mm in Group 1, 17.6 ± 2 mm in Group 2 (p = 0.004). The mean width of the infraspinatus tendon (ISP) tendon was 17.7 ± 1.4 mm in Group 1, 18.3 ± 2.1 mm in Group 2 (p = 0.02).

Conclusion
The anatomical data present in this paper may serve as a tool for surgeons to properly manage PTRCTs. The findings of the present study aimed to set the first step towards reaching unanimity to establish international cut-off values to perform surgery. Additionally, they could widely increase diagnostic accuracy, improving both conservative and surgical approaches. Lastly, further clinical trials using more accurate diagnostic MRI tools are required to better define the anatomical differences between PTRCT and healthy patients.

Effect of day time on smartphone use posture and related musculoskeletal disorders risk: a survey among university students
Authors: Jacquier-Bret Julien , Gorce Philippe 
Published: September 2023

Abstract
Background
Musculoskeletal disorders (MSDs) are one of the most important problems among young smartphone users worldwide. Portability leads to a wide variety of postures during the different activities of the day. The objective evaluation of these postures coupled with ergonomic tools allows evaluating the level of MSD risk to which users are exposed.

Methods
The purpose was to investigate the effect of the time of day on the posture adopted during smartphone use among university students. The study was conducted through a cross-sectional survey of 263 university sports students. Four time of day, i.e. morning, afternoon, evening and night, and a taxonomy of 41 postures called SmarTaxo were considered. SmarTaxo included 18 sitting, 11 standing, 10 lying and 2 walking postures and their ergonomic score. After checking the normality of the data, a non-parametric Kruskal–Wallis test was used to study the effect of the time of day on the use duration of the different postures.

Results
The total mean duration use per typical weekday was 5.39 ± 2.19 h for males and 5.15 ± 1.60 h for females with maximal duration during evening. The average smartphone use durations were statistically longer in afternoon and evening for all sitting (9.44 and 9.22 min respectively, p < 0.05) and calling (3.38 and 3.33 min respectively, p < 0.05) postures. The longest duration for standing postures was recorded for afternoon (8.91 min, p < 0.05). The lying postures were significantly more present in evening (19.36 min). Some postures were more used during a time of day. The side-lying posture was used more in evening and has an ergonomic score of 6, i.e. a high MSD risk.

Conclusions
The survey showed that users are exposed to MSDs regardless of posture and time of day. Sitting postures are used more in the morning and afternoon while lying postures are used more in the evening. As long as the rate of use is so high (> 5 h per day), young people will remain highly exposed to MSDs.
