Understanding the contents and gaps in sexual and reproductive health toolkits designed for adolescence and young adults: a scoping review.

Adolescence is a crucial stage of physical and sexual maturation and development and a period in which understanding sexual and reproductive health (SRH) is important. SRH interventions and toolkits provide a range of valuable resources and information to young people, educators, and members of the community on numerous topics, including contraception and puberty. The usefulness and reliability of these available toolkits have not been previously studied, thus limiting our understanding of their appropriateness and contents. Hence, this scoping review aimed to synthesize the available toolkits aimed at the SRH of adolescents and young adults to understand the contents, design, and information gaps. A systematic search was conducted of 6 medical databases and 12 gray literature sites. Sixteen toolkits published globally before May 2023 were included in our review. The majority of toolkits (n = 12) contained information related to general SRH knowledge and contraception, whereas only 3 contained information on teenage pregnancy. We found that aiming the toolkits toward educators and health care workers was a favorable design over targeting adolescents and young adults directly and that vulnerable youth-including LGBTQI+ (lesbian, gay, bisexual, transgender, queer or questioning, asexual or allied, intersex, and additional identities) and youth from humanitarian settings-were not well represented. We identified key gaps in the inclusion of information in a range of SRH topics, such as LGBTQI+ sexuality, teenage pregnancy, and safe abortion, in the currently available SRH toolkits and their lack of applicability in a global context. Furthermore, we provide recommendations for areas of improvement to encourage adolescents' agency in their SRH education.

Comparative Molecular and Biological Characteristic of the Systemic Inflammatory Response in Adult and Old Male Wistar Rats with Different Resistance to Hypoxia.

Morphological, molecular, and biological features of the systemic inflammatory response induced by LPS administration were assessed in adult and old male Wistar rats with high and low resistance to hypoxia. In 6 h after LPS administration, mRNA expression levels of Hif1a, Vegf, Nfkb, and level of IL-1β protein in old rats were higher than in adult rats regardless of hypoxia tolerance. The morphometric study showed that the number of neutrophils in the interalveolar septa of the lungs was significantly higher in low-resistant adult and old rats 6 h after LPS administration. Thus, in old male Wistar rats, systemic inflammatory response is more pronounced than in adult rats and depends on the initial tolerance to hypoxia, which should be considered when developing new approaches to the therapy of systemic inflammatory response in individuals of different ages.

The relationship between oxidative balance score and erectile dysfunction in the U.S. male adult population

Oxidative stress strongly influences the pathophysiology of erectile dysfunction (ED). In this study, we used the oxidative balance score (OBS), a composite index, to measure the effects of oxidative stress triggered by diet and lifestyle factors. Here, we conducted a cross-sectional study to determine the statistical relationship between OBS and ED among adult males in the U.S. The data from 3318 participants in the National Health and Nutrition Examination Survey (NHANES) 2001–2004 were analyzed. Weighted logistic regression was used to correct for confounding factors and acquire nationwide representative estimates. Generalized additive modeling was used to explore the nonlinear relationship. We also supplemented subgroup and sensitivity analysis to examine the robustness of the main results. Multivariate logistic regression indicated a consistent negative linear association between OBS and ED across all participants [OR (95% CI) = 0.96 (0.94, 0.98)]. After categorizing OBS into tertiles, participants in the highest tertile had 43% lower odds of having ED than those in the lowest tertile [OR (95% CI) = 0.57 (0.37, 0.87)]. The generalized additive model also visualized the linear trend of this association. Furthermore, this linear relationship remained relatively consistent, regardless of whether subgroup or sensitivity analyses were performed. Our findings suggest that adopting a lifestyle and diet pattern that promotes favorable OBS may effectively protect against the development of ED, regardless of the underlying causes.

The effect of magnesium sulfate on memory and anxiety-like behavior in a rat model: an investigation of its neuronal molecular mechanisms

ABSTRACT Background Anxiety is an adaptive response to potentially threatening conditions. Excessive and uncontrolled anxiety responses become nonadaptive and cause anxiety disorders. To better understand the anxiety-modulating effects of Mg sulfate, behavioral test batteries in the assessment of anxiety and learning and memory functions were performed simultaneously over a time period. This study also examines the effects of Mg sulfate compared to diazepam, an anxiolytic drug with amnestic effects on anxiety-like behavior, as well as possible oxidative-nitrosative stress and hippocampal changes in male rats exposed to predator odor. Methods Young adult Sprague-Dawley male rats were used. The rats were assessed using a comprehensive neurobehavioral test battery consisting of novel object recognition, open field, and successive alleys tasks. Anxiety was induced by cat odor, and diazepam and Mg were used as study drugs. Of the frontal cortex and hippocampus, the state of total oxidant and antioxidant and NO levels and histological examination of hippocampal CA1, CA2, CA3, and DG regions were performed. Results Diazepam- and Mg-treated rats showed an improvement in anxiety-related behavior to predator odors. Furthermore, Mg treatment alleviated some of the increasing oxidative stress in the frontal cortex and hippocampus of rats, while diazepam treatment in particular enhanced hippocampal oxidant and antioxidant activity. In addition, brain NO increase induced by animal odor exposure or diazepam treatment was ameliorated by Mg administration. Conclusions Overall, our work suggests that Mg had a partial anxiolytic effect on anxiety-like behaviors, although not as much as diazepam, and this effect varied depending on the dose. Mg treatment might counteract increased oxidative stress and elevated NO levels in the brain.

Semen Cryopreservation in Oncofertility

Oncofertility, an interdisciplinary field, aims at improving the uality of life of cancer patients prone to iatrogenic infertility by offering fertility preservation options for a potentially fertile future. Semen cryopreservation (SC) is a well-established and effective way of preserving fertility in adolescent and young adult cancer-diagnosed males as they face potential fertility loss due to cancer and its treatments. The pathophysiology of certain cancers, such as testicular cancer or Hodgkin’s lymphoma, has been shown to have an adverse effect on semen uality. Ablative therapies like chemotherapy and radiotherapy can result in compromised sperm parameters depending on the dose and the type of the drug or radiation. Hence, it is recommended to encourage cancer-diagnosed males to store sperm prior to gonadotoxic therapy to restore potential fertility in the future. Despite the feasibility of SC, this option remains underutilised due to several limitations.

Fish oil supplementation during pregnancy decreases liver endocannabinoid system and lipogenic markers in newborn rats exposed to maternal high-fat diet.

Maternal high-fat diet (HF) programs obesity, metabolic dysfunction-associated steatotic liver disease (MASLD), hypertriglyceridemia, and hyperglycemia associated with increased endocannabinoid system (ECS) in the liver of adult male rat offspring. We hypothesized that maternal HF would induce sex specific ECS changes in the liver of newborn rats, prior to obesity onset, and maternal fish oil (FO) supplementation would reprogram the ECS and lipid metabolism markers preventing liver triglycerides (TG) accumulation. Female rats received a control (CT) (10.9% fat) or HF (28.7% fat) diet 8weeks prior to mating and during pregnancy. A subgroup of HF dams received 3% FO supplementation in the HF diet (35.4% fat) during pregnancy (HFFO). Serum hormones and liver TG, ECS, lipid metabolism, oxidative stress and autophagy markers were assessed in male and female newborn offspring. Maternal HF diet increased liver cannabinoid receptor 1 (CB1) in males and decreased CB2 in females, with no effect on liver TG. Maternal FO supplementation reduced liver CB1 regardless of the offspring sex, but reduced TG liver content only in females. FO reduced the liver content of the endocannabinoid anandamide in males, and the content of 2-arachidonoylglycerol in both sexes. Maternal HF increased lipogenic and decreased lipid oxidation markers, and FO induced the opposite regulation in the liver of offspring. Prenatal HF and FO differentially modulate liver ECS in the offspring before obesity and MASLD development. These results suggest that maternal nutrition at critical stages of development can modulate the offspring's ECS, predisposing or preventing the onset of metabolic diseases.

Comparison of firocoxib and meloxicam for pain mitigation in goats undergoing surgical castration

Castration is a common husbandry practice in food animal management. Castration reduces aggression, prevents indis­criminate breeding, and improves carcass quality. For male goats intended to be kept as pets, castration is recommended close to sexual maturity (6-8 m) to allow for increased urethral diameter. A larger urethral diameter lowers the chances of ure­teral obstruction occurring. There are currently no approved analgesic drugs for surgical castration in goats. Veterinarians must extrapolate analgesic data from other livestock species to try to mitigate pain in goats. Sheep and cattle are commonly used, but there is little research supporting best practices of pain mitigation in goats. This study sought to examine the ef­fects of firocoxib and meloxicam after surgical castration in crossbred goats.

The positive impact of smoking on poor sleep quality is moderated by IGF1 levels in cerebrospinal fluid: a case-control study among Chinese adults

ObjectivePrevious research indicates associations between cigarette smoking, insulin-like growth factor-1 (IGF1), and sleep disturbances. This study aimed to examine the association between smoking and sleep quality and investigate the moderating role of IGF1.MethodsThis case-control study involved 146 Chinese adult males (53 active smokers and 93 non-smokers) from September 2014 to January 2016. Sleep quality and disturbances were evaluated using the Pittsburgh Sleep Quality Index (PSQI), which includes seven scales. Pearson correlation analysis and logistic regression analysis were utilized to examine the link between IGF1 levels in cerebrospinal fluid (CSF) and PSQI scores. The effect of IGF1 was assessed using the moderation effect and simple slope analysis, with adjustments made for potential confounders.ResultsActive smokers exhibited significantly higher global PSQI scores and lower IGF1 levels in CSF compared to non-smokers. A significant negative correlation was observed between IGF1 and PSQI scores (â = -0.28, P < 0.001), with a stronger association in non-smokers (Pearson r = -0.30) compared to smokers (Pearson r = -0.01). Smoking was associated with higher global PSQI scores (â = 0.282, P < 0.001), and this association was moderated by IGF1 levels in CSF (â = 0.145, P < 0.05), with a stronger effect at high IGF1 levels (Bsimple = 0.402, p < 0.001) compared to low IGF1 levels (Bsimple = 0.112, p = 0.268). Four subgroup analysis revealed similar results for sleep disturbances (Bsimple = 0.628, P < 0.001), with a marginal moderation effect observed on subjective sleep quality (Bsimple = 0.150, P = 0.070). However, independent associations rather than moderating effects were observed between IGF1 and sleep efficiency and daytime disturbance.ConclusionWe provided evidence to demonstrate the moderation effect of IGF1 on the relationship between smoking and sleep in CSF among Chinese adult males.

A rare case of multisystemic Langerhans cell histiocytosis in an adult affecting the thyroid gland, skeletal system, and pituitary gland: A case report.

Langerhans cell histiocytosis (LCH) is a rare disorder affecting usually children and rarely adults. The most common site affected is bone. The involvement of the thyroid gland in LCH is extremely rare and it is usually observed in an adult as a multisystemic disease. Adult males presented with anterior neck swelling, and fine needle aspiration cytology (FNAC) diagnosed it as suspicious for malignancy. On frozen sectioning, differential diagnosis was given as non-Hodgkin lymphoma and poorly differentiated malignancy. On immunohistochemistry (IHC), tumor cells were positive for CD1a and S100p. Thus, the final diagnosis offered was LCH-thyroid. The pathogenesis is unclear and believed to be related to immune dysfunction, cytokine mediators, viral infection, smoking, and genetic factors. Due to its rarity, thyroid LCH is often misinterpreted as other common disorders of the thyroid and results in delayed diagnosis. This case highlights the importance of histomorphology and the use of ancillary techniques such as IHC to arrive at a diagnosis in time and hence the treatment.

Nymphomyiidae from the Russian Far East and bordering territories are revised, including data on taxonomy, redescriptions, and results of DNA barcoding. Nymphomyia orientalis sp. nov. with two subspecies N orientalis orientalis subsp. nov. and N. orientalis makcha subsp. nov. are described and information on biology, ecology and distribution are presented. Key of Nymphomyia species for adult males and females of the world is provided. Three species delimitation approaches (ASAP, mPTP, GMYC) using the mitochondrial gene cytochrome c oxidase I (COI) confirm validity of described taxa as well as available nymphomyiids in GenBank. Morphologically indistinguishable specimens of N. orientalis sp. nov. from Makcha and Polovinka rivers belongs to separate mOTUs with the lowest distances in the genus 1.99% that is the lower interspecific threshold.

Investigating the antecedents of mHealth adoption by older adults in a lower-middle income country: The PLS-MGA approach

ABSTRACT The adoption of technology and the rising digital divide among the older adult population, predominantly in lower-middle income countries such as Bangladesh, have posed a precarious challenge. Hence, the time has come to navigate this upcoming challenge. Thus, the current research aims to investigate the impact of perceived usefulness (PU), perceived ease of use (PE), and perceived risk (PR) on the behavioral intention to adopt mHealth (BI). Furthermore, multigroup analysis (MGA) is used to examine BI regarding gender and income groups. Data from 140 older adults in Bangladesh were gathered and later analysed using Partial Least Squares Structural Equation Modeling (PLS-SEM) to estimate the measurement and structural model parameters and produce concurrent bootstrap evaluations. The findings revealed that PE and PU substantially affect the intention to adopt mHealth, whereas PR has small effect on mHealth adoption. Furthermore, the MGA depicts that the effect of PR is statistically significant for older adult males and females. Additionally, the effect of PE on behavioral intention to adopt mHealth between income groups (lower income vs. higher income) is significant. Therefore, this research advances our theoretical and empirical understanding by yielding new scholarly evidence in the domain of mHealth adoption by older adults. Finally, the paper concludes with augmented practical considerations concerning the adoption of mHealth as a technology by older adults, which will assist in alleviating the digital divide for any such lower-middle income country across the globe.

A Case of Non-Seminomatous Germ Cell Tumor Complicated by Tumor Thrombus in an Active Duty Soldier.

Testicular malignancies commonly affect adolescent and young adult males. Although they tend to respond well to cisplatin-based chemotherapy with excellent overall survival, complications such as inferior vena cava tumor thrombus are rare and can be associated with high morbidity and mortality. We present a case of tumor thrombus in a 21-year-old active duty male with a newly diagnosed stage IIIB non-seminomatous germ cell tumor presenting with extensive left lower extremity swelling. Ultrasound with Doppler was notable for significant thrombus of the left common femoral, femoral, and popliteal vein. Computed tomography imaging revealed extensive thrombus of the inferior vena cava, left iliac veins, and left gonadal vein with sparing of the left renal vein. Endovascular thrombectomy was performed with pathologic analysis confirming the presence of malignant cells consistent with tumor thrombus. The patient continued subsequent non-seminomatous germ cell tumor treatment without complications.

Variation in dietary composition of the Banna fanged frog (Limnonectes bannaensis Ye, Fei, Xie & Jiang, 2007) from Vietnam

Abstract The Banna fanged frog (Limnonectes bannaensis) is known from China, Laos, and Vietnam; however knowledge about the natural history and dietary requirements of this species is virtually lacking. In this study, we provide data on the variation in dietary composition of L. bannaensis based on stomach-flushing of 117 individuals (41 males and 76 females) captured and subsequently released during our recent field work in Son La Province, northwestern Vietnam. A total of 19 prey categories with 513 items, comprising 502 items of invertebrates, seven items of vertebrates, and four unidentified items were found in the stomachs of L. bannaensis. The most important groups among the prey of L. bannaensis were Coleoptera (38.04%), followed by Hymenoptera (9.31%), Araneae (7.93%), Polydesmida (7.07%), Orthoptera (6.37%), Hemiptera (5.23%), and Lepidoptera (5.01%). Adult males (16 prey categories) consumed preys with slightly lower diversity than adult females (17 prey categories). There was 88.25% overlap in the diet between males and females and in both sexes the trophic spectrum was similar, predominantly consisting of Coleoptera, Polydesmida, Araneae, Hymenoptera, Orthoptera, Lepidoptera, and Hemiptera.

Effect of Stanozolol and/or Cannabis Abuse on Hypertrophic Mechanism and Oxidative Stress of Male Albino Rat Cardiac Tissue in Relation to Exercise: A Sport Abuse Practice.

Adolescents commonly co-abuse many drugs including anabolic androgenic steroids either they are athletes or non-athletes. Stanozolol is the major anabolic used in recent years and was reported grouped with cannabis. The current study aimed at evaluating the biochemical and histopathological changes related to the hypertrophic effects of stanozolol and/or cannabis whether in condition of exercise practice or sedentary conditions. Adult male Wistar albino rats received either stanozolol (5mg/kg, s.c), cannabis (10mg/kg, i.p.), and a combination of both once daily for two months. Swimming exercise protocol was applied as a training model. Relative heart weight, oxidative stress biomarkers, cardiac tissue fibrotic markers were evaluated. Left ventricular morphometric analysis and collagen quantification was done. The combined treatment exhibited serious detrimental effects on the heart tissues. It increased heart tissue fibrotic markers (Masson's trichrome stain (p < 0.001), cardiac COL3 (p < 0.0001), and VEGF-A (p < 0.05)), lowered heart glutathione levels (p < 0.05) and dramatically elevated oxidative stress (increased malondialdehyde (p < 0.0001) and 8-OHDG (p < 0.0001)). Training was not ameliorating for the observed effects. Misuse of cannabis and stanozolol resulted in more hypertrophic consequences of the heart than either drug alone, which were at least largely assigned to oxidative stress, heart tissue fibrotic indicators, histological alterations, and morphometric changes.

The Effect of Nutrients on Subjective Accomplishment at Work: Results from a Health Survey and a Single-Arm Dietary Intervention Study

In Japan, many workers are exposed to chronic stress, sleep deprivation, and nutritional imbalance. They tend still to go to work when ill, leading to decreased work performance and productivity, which has become a major social problem. We conducted a human entry study with the aim of finding a link between these two factors and proposing an optimized diet, believing that a review of diet may lead to an improvement in labor productivity. In this study, we used subjective accomplishment (SA) as a measure of productivity. First, we compared nutrient intake between groups with high and low SA using data from a health survey of 1564 healthy male and female adults. Significant differences were found in the intake of 13 nutrients in males and 15 nutrients in females, including potassium, vitamin A, insoluble fiber, and biotin. Recommended daily intake of these nutrients was determined from survey data. Next, we designed test meals containing sufficient amounts of 17 nutrients and conducted a single-arm intervention study (registration code UMIN000047054) in Kameyama City, Mie Prefecture, Japan. Healthy working adults (males and females aged 20–79 years) were recruited and supplied with test meals, which were eaten once a day 5 days a week for 8 weeks. SA was significantly higher and daytime sleepiness (DS) was significantly lower after lunch on workdays in younger participants (under 60 years) when they ate the test meals as breakfast or lunch. Our results suggest that SA and DS, which change daily, are strongly influenced by the meal eaten before work, and that taking the 17 nutrients may help prevent presenteeism and improve labor productivity.

[Characteristics, Sources Apportionment, and Health Risks of PM2.5-bound PAHs and Their Derivatives Before and After Heating in Zibo City].

Atmospheric polycyclic aromatic hydrocarbons (PAHs) and their derivatives are a global problem that influences the environment and threatens human health. To investigate the characteristics, sources, and health risk assessment of PM2.5-bound PAHs and their derivatives, PM2.5 were collected at an urban site in Zibo from November 5 to December 26, 2020, and the concentrations of 16 conventional PAHs, nine NPAHs, and five OPAHs in PM2.5 were analyzed using gas chromatography-mass spectrometry. Source apportionment of PAHs and their derivatives was conducted using diagnostic ratios and a PMF model, and the health risks of PAHs and their derivatives to adult men and women were evaluated using the source-dependent incremental lifetime cancer risk (ILCR) model. The results showed that the average concentrations of ∑16pPAHs, ∑9NPAHs, and ∑5OPAHs in PM2.5 of Zibo City during the sampling period were (41.61 ± 13.40), (6.38 ± 5.70), and (53.20 ± 53.47) ng·m-3, respectively. The concentrations of the three PAHs increased significantly after heating, which were 1.31, 2.04, and 5.24 times larger than those before heating. During the sampling period, Chr, BaP, and BaA were the dominant components of pPAHs; 9N-Ant and 2N-Flt + 3N-Flt were the dominant components of NPAHs; and ATQ and BZO were the dominant components of OPAHs. Source apportionment results showed that motor vehicles were the main source of PAHs and their derivatives in PM2.5 before heating, whereas after heating, the main sources were the mixed source of coal and biomass combustion and secondary formation. The total BaP equivalent (TEQ) was 14.5 ng·m-3 during the sampling period, and the TEQ increased significantly after heating, which was approximately 1.2 times of that before heating. Assisted by the individual PAH source apportionment results, the ILCR of PM2.5-boundPAHs and NPAHs in Zibo City had a certain potential carcinogenic risk for adult males (1.06 × 10-5) and females (9.32 × 10-6). Among them, the health risks of PAHs from gasoline vehicles, diesel vehicles, and coal/biomass combustion were significantly higher than those from other emission sources.

Tert-butylhydroquinone prevents cyclophosphamide induce lung toxicity in rats via inhibiting oxidative stress and apoptosis: in vivo and in silico study

BackgroundCyclophosphamide (CP) is a chemotherapeutic and immunosuppressive agent that induces oxidative stress, causing lung tissue damage.AimThe study aims to explore the antioxidant role of tert-butylhydroquinone (TBHQ) in ameliorating CP-induced lung toxicity exhibited as oxidative stress and programmed cell death.MethodsThirty-two adult male rats were allocated randomly into four groups: group 1 (control), group 2 TBHQ 50 mg/kg orally for 14 days, and group 3 single dose of (200 mg/kg, CP, i.p.) on the 9th day. In group 4, TBHQ (50 mg/kg, orally) was provided for 14 days, and (200 mg/kg, CP, i.p.) was administrated on the 9th day. Rats’ body and lung weight were measured. Oxidative stress marker malondialdehyde (MDA) and pulmonary tissue enzymatic antioxidant levels were assessed: glutathione S transferase, catalase, superoxide dismutase, and glutathione peroxidase. Additionally, glutathione level was measured. Assessment of the levels of TNF-α, IL-1β, and IL-6 were done as well as histopathological and immunohistochemistry investigations. Molecular docking studies of the protein structures of p53-MDM2, IL-6, and IL-1β were performed.ResultsCP-intoxicated rats demonstrated a significant decline (CAT, GPx, SOD, GST, and GSH) levels and a significant increase in MDA levels. The proinflammatory parameters (TNF-α, IL-6, IL-1ß) were significantly elevated in group 3. The noted biochemical changes, accompanied by histopathological destruction, indicate CP-induced pulmonary tissue injury. TBHQ played a protective role by attenuating most of the aforementioned biochemical alterations and histopathological distortions in rats’ lungs.ConclusionsTBHQ might be utilized as a potential ameliorative agent to inhibit CP-induced pulmonary toxicity via TBHQ’s antioxidant and anti-inflammatory effects.

Characterization of sexual maturity-associated N6-methyladenosine in boar testes

BackgroundThe health and size of the testes are crucial for boar fertility. Testicular development is tightly regulated by epigenetics. N6-methyladenosine (m6A) modification is a prevalent internal modification on mRNA and plays an important role in development. The mRNA m6A methylation in boar testicular development still needs to be investigated.ResultsUsing the MeRIP-seq technique, we identify and profile m6A modification in boar testes between piglets and adults. The results showed 7783 distinct m6A peaks in piglets and 6590 distinct m6A peaks in adults, with 2,471 peaks shared between the two groups. Enrichment of GO and KEGG analysis reveal dynamic m6A methylation in various biological processes and signalling pathways. Meanwhile, we conjointly analyzed differentially methylated and expressed genes in boar testes before and after sexual maturity, and reproductive related genes (TLE4, TSSK3, TSSK6, C11ORF94, PATZ1, PHLPP1 and PAQR7) were identified. Functional enrichment analysis showed that differential genes are associated with important biological functions, including regulation of growth and development, regulation of metabolic processes and protein catabolic processes.ConclusionThe results demonstrate that m6A methylation, differential expression and the related signalling pathways are crucial for boar testicular development. These results suggest a role for m6A modification in boar testicular development and provided a resource for future studies on m6A function in boar testicular development.
