- Abstract
Objective: Military sexual trauma (MST), childhood trauma, and combat trauma are prevalent among U.S. military personnel. Cumulative trauma exposure may hinder posttraumatic growth, a positive psychological change following traumatic events, while social support can facilitate this growth. Understanding the influence of these traumas and social support on longitudinal posttraumatic growth is crucial., Method: We assessed 1,230 veterans at 6, 9, 12, 18, and 24 months postinitial survey. Latent class analysis identified trauma experience classes, and latent growth models examined posttraumatic growth trajectories, incorporating social support as a time-varying covariate., Results: The latent class analysis revealed four classes: high trauma exposure, moderate childhood trauma-moderate combat trauma, high MST-moderate combat trauma, and combat trauma only. Veterans in the combat-only class reported significant posttraumatic growth. The moderate childhood trauma-moderate combat class exhibited consistently low growth. Veterans in the high MST-moderate combat class showed slightly higher initial growth but no significant change over time. The high trauma exposure class experienced a significant decline in growth., Conclusions: Social support significantly predicted posttraumatic growth, with varying impacts across trauma classes. Interventions could be vital for survivors of MST, childhood trauma, or compounded traumas to enhance posttraumatic growth among military veterans.

- Abstract
Purpose: M2-type tumor-associated macrophages (TAM) residing in the tumor microenvironment (TME) have been linked to tumor invasiveness, metastasis and poor prognosis. M2 TAMs suppress T cell activation, silencing the recognition of the cancer by the immune system. Targeting TAMs in anti-cancer therapy may support the immune system and immune-checkpoint inhibitor therapies to fight the cancer cells. We aimed to develop a PET tracer for the imaging of M2 TAM infiltration of cancer, using activated legumain as the imaging target., Basic Procedures: Two P1-mimicking inhibitors with a cyano-warhead were labeled with carbon-11 and evaluated in vitro and in vivo with a CT26 tumor mouse model. Target expression and activity were quantified from RT-qPCR and in vitro substrate conversion, respectively. The co-localization of legumain and TAMs was assessed by fluorescence microscopy. The two tracers were evaluated by PET with subsequent biodistribution analysis with the dissected tissues. Parent-to-total radioactivity in plasma was determined at several time points after i.v. tracer injection, using reverse phase radio-UPLC., Main Findings: Legumain displayed a target density of 40.7 ± 19.1 pmol per mg total protein in tumor lysate (n = 4) with high substrate conversion and colocalization with M2 macrophages in the tumor periphery. [
11 C]1 and [11 C]2 were synthesized with >95 % radiochemical purity and 12.9-382.2 GBq/μmol molar activity at the end of synthesis. We observed heterogeneous tumor accumulation in in vitro autoradiography and PET for both tracers. However, excess unlabeled 1 or 2 did not compete with tracer accumulation. Both [11 C]1 and [11 C]2 were rapidly metabolized to a polar radiometabolite in vivo., Principal Conclusions: The legumain tracers [11 C]1 and [11 C]2, synthesized with high radiochemical purity and molar activity, accumulate in the legumain-positive CT26 tumor in vivo. However, the lack of competition by excess compound questions their specificity. Both tracers are rapidly metabolized in vivo, requiring structural modifications towards more stable tracers for further investigations., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 The Authors.

- Abstract
Background: Altitude influences bicarbonate levels, it is a variable that is hardly considered in diagnosing Renal Tubular Acidosis (RTA), so it should be a factor to consider when diagnosing this pathology, especially at 2250 mts over the sea level as it is the case of Mexico City. RTA is most often misdiagnosed. Regarding of this, the present study established reference limits for bicarbonate levels in healthy children without pathologies associated with alterations in the acid-base balance in Mexico City and it´s metropolitan area., Methods: A total of 267 healthy pediatric patients were included, within normal estimated glomerular filtration rate (eGFR), and without any associated pathology of any alteration in the acid-base balance., Results: Compared to older children, children younger than two years of age showed statistically higher levels of calcemia and cystatin C. On the other hand, this same group showed lower values of creatininemia, pCO
2 , and HCO3 - . Percentile 50 of bicarbonate in children under two years of age were 19.9 mEq/L and 21.9 mEq/L in those over that age. A correlation was identified between HCO3 - levels and pCO2 (r = 0.68; p < 0.001)., Conclusions: In the study population, an effect of altitude on blood levels of pCO2 and HCO3- was observed., (© 2024.

- Abstract
Background: Access to quality healthcare is essential to the well-being of U.S. veterans. Little is known about what drives veterans' healthcare decisions. The purpose of this study was to explore factors that drive healthcare choices in veterans, and their experiences in the Veterans Health Administration (VA) and non-VA healthcare settings., Methods: Fifty-nine veterans participated in eight focus groups. Participants were asked to discuss factors that led to their choice of provider and their healthcare experiences. Thematic analysis was conducted to reveal themes around healthcare choices and use., Results: VA and non-VA users described positive experiences with care. VA users reported cost, quality, and ease of care as reasons for use. Non-VA healthcare setting users reported eligibility issues, negative perceptions of the VA, administrative bureaucracy, and lack of continuity of care as reasons they chose not to use VA care. VA users reported difficulty with red tape, continuity of care, limitations to gender specific care, and having to advocate for themselves., Conclusions: Veterans were satisfied with care regardless of where they received it. Experiences with civilian providers indicate that more could be done to provide veterans with choices in the care they receive. Despite positive experiences with the VA, the veterans highlighted needed improvements in key areas.

- Abstract
Empyema necessitatis is a rare complication of an untreated or inadequately controlled empyema. We present the case of an 11-year-old female adolescent living in precarious conditions, overcrowding, incomplete vaccinations, irregular dental hygiene, and no significant family or personal medical history. The patient started with symptoms one week prior to her hospitalization, presenting a persistent sporadic dry cough, and was later diagnosed with complicated pneumonia, resulting in the placement of an endopleural tube. Vancomycin (40 mg/kg/day) and ceftriaxone (75 mg/kg/day) were administered. However, the clinical evolution was unfavorable, with fever and respiratory distress, so a right jugular catheter was placed. The CT scan showed a loculated collection that occupied the entire right lung parenchyma and pneumothorax at the right upper lobe level. After four days of treatment, the patient still presented purulent drainage with persistent right pleural effusion syndrome. P. melaninogenica and D. pneumosintes were identified from the purulent collection on the upper right lobe, so the antimicrobial treatment was adapted to a glycopeptide, Teicoplanin, at a weight-based dosing of 6 mg/kg/day and Metronidazole at a weight-based dosing of 30 mg/kg/day. In addition, VAC therapy was used for 26 days with favorable resolution.

- Abstract
Using orthopedic devices or prosthetic joints to treat various conditions is expected in a Traumatology and Orthopedics Unit. Recently, the materials used to build these different devices have evolved; however, pathogens can still infect these materials. Additionally, the immune system has limitations when defending against these pathogens, which results in bacterial infections like Staphylococcus aureus , Methicillin-susceptible Staphylococcus aureus ( MSSA ) and Methicillin-resistant Staphylococcus aureus ( MRSA ). A total of 276 patients who attended the Traumatology and Orthopedics Unit of our hospital from 1 June 2018 to 1 June 2019, were included in the present study. Our study analyzed the incidence of S. aureus and other bacterial pathogens in the surgical sites of patients with orthopedic implants, as well as the most used types of implants and implant materials. The specimens obtained from the surgical sites of the patients were cultured in anaerobic and aerobic media for subsequent identification using their phenotypic characteristics. Subsequently, antibiotic susceptibility tests were performed to establish the appropriate treatment. The primary pathogens identified were Staphylococcus aureus (26.4%), followed by Escherichia coli (21.0%) and Staphylococcus epidermidis (15.8%). The most commonly used implants were plates (41.7%), followed by endomedullary nails (20%), Kirschner wires (14.1%), and fixators (10.1%). As for the anatomical regions of the implants, the most frequent sites were the legs, followed by the thighs, wrists, and ankles. The pathogens were more susceptible to ciprofloxacin (95%), clindamycin (89%), and cefotaxime (86%). S. aureus is the primary infectious agent in our hospital, with an incidence of 26.4% after the placement of orthopedic implants. Although its incidence was lower compared to other tertiary hospitals, it is necessary to improve aseptic techniques in such a way as to reduce the incidence of this pathogen further.

- Abstract
Surgical intervention is a key element in the management of patients diagnosed with mucormycosis. A retrospective cohort study was carried out, in which patients with a proven diagnosis of mucormycosis were evaluated over a period of 10 years, according to the MSGERC criteria. A descriptive analysis of the clinical characteristics, comorbidities, imaging, and microbiology studies, as well as medical and surgical treatment and the type of prosthesis was carried out. A total of 22 cases were identified, of which 54.5% (n = 12) of the population were men. Furthermore, 77.2% (n = 17) of the population had diabetes mellitus. The main antifungal treatment implemented was liposomal amphotericin B (77.2%, n = 17). The most affected structures in our patients were the paranasal sinuses (n = 18; 81%), followed by the maxilla and orbit (n = 15; 68%), nose (n = 12; 54%), central nervous system (n = 11; 50%), and skin and soft tissues (n = 2; <1%). Of the total population, 59.09% (n = 13) of patients underwent maxillofacial surgery, of which 61.53% (n = 8) required some type of prosthetic rehabilitation. Orbital exenteration and maxillectomy were the most frequent surgeries, accounting for 69.23% (n = 9), while skull base drainage was performed in four patients (30.76%). Of the total number of patients (n = 22), eight died (36.36%). Appropriate surgical management according to the affected structures, considering not only increasing the patient's survival, but also considering the aesthetic and functional consequences, will require subsequent rehabilitation.

- Abstract
We evaluated the specificity of the primers OPF-01, P54, and 1253 to identify A. fumigatus , A. flavus , and A. niger , respectively, with the RAPD-PCR method. Eighty-two isolates belonging to the sections Fumigati , Flavi , and Nigri were used. The isolates were identified by phenotypic (macro- and micromorphology) and genotypic (partial sequences of the BenA gene) methods. The RAPD-PCR method was used to obtain polymorphic patterns with the primers OPF-01, P54, and 1253. The specificity of the polymorphic patterns of the isolates of each species was evaluated through the UPGMA clustering method and logistic regression model. All isolates of the genus Aspergillus were identified at the section level by macro- and micromorphology showing the typical morphology of the sections Fumigati , Flavi , and Nigri , and the species were identified by the construction of the phylogeny of the partial sequence of the BenA gene. The patterns' polymorphic strains obtained with the primers OPF-01, P54, and 1253 for the isolates of A. fumigatus , A. flavus , and A niger , respectively, showed the same polymorphic pattern as the reference strains for each species. To verify the specificity of the primers, they were tested with other species from the sections Fumigati , Flavi and Nigri. The results support that the primers OPF-01, P54, and 1253 generate polymorphic patterns by RAPD-PCR species specific to A. fumigatus , A. flavus , and A. niger , respectively.

- Abstract
Fasciola hepatica has a complex lifecycle with multiple intermediate and definitive hosts and influenced by environmental factors. The disease causes significant morbidity in children and its prevalent worldwide. There is lack of data about distribution and burden of the disease in endemic regions, owing to poor efficacy of the different diagnostic methods used. A novel PCR-based test was developed by using a portable mini-PCR
® platform to detect Fasciola sp. DNA and interpret the results via a fluorescence viewer and smartphone image analyzer application. Human stool, snail tissue, and water samples were used to extract DNA. Primers targeting the ITS-1 of the 18S rDNA gene of Fasciola sp. were used. The limit of detection of the mini-PCR test was 1 fg/μL for DNA samples diluted in water, 10 fg/μL for Fasciola /snail DNA scramble, and 100 fg/μL for Fasciola /stool DNA scramble. The product detection by agarose gel, direct visualization, and image analyses showed the same sensitivity. The Fh mini-PCR had a sensitivity and specificity equivalent to real-time PCR using the same specimens. Testing was also done on infected human stool and snail tissue successfully. These experiments demonstrated that Fh mini-PCR is as sensitive and specific as real time PCR but without the use of expensive equipment and laboratory facilities. Further testing of multiple specimens with natural infection will provide evidence for feasibility of deployment to resource constrained laboratories.- Published

- Abstract
Current practices for structural analysis of extremely large-molecular-weight polysaccharides via solution-state nuclear magnetic resonance (NMR) spectroscopy incorporate partial depolymerization protocols that enable polysaccharide solubilization in suitable solvents. Non-specific depolymerization techniques utilized for glycosidic bond cleavage, such as chemical degradation or ultrasonication, potentially generate structural fragments that can complicate complete and accurate characterization of polysaccharide structures. Utilization of appropriate enzymes for polysaccharide degradation, on the other hand, requires prior structural knowledge and optimal enzyme activity conditions that are not available to an analyst working with novel or unknown compounds. Herein, we describe an application of a permethylation strategy that allows the complete dissolution of intact polysaccharides for NMR structural characterization. This approach is utilized for NMR analysis of Xylella fastidiosa extracellular polysaccharide (EPS), which is essential for the virulence of the plant pathogen that affects multiple commercial crops and is responsible for multibillion dollar losses each year., (© 2023 The Authors.

- Abstract
Insomnia is highly prevalent among military veterans, with rates nearly double that of civilian populations. Insomnia typically co-occurs with other psychological problems, including substance use (e.g. cannabis) and perceived stress. Much of the research focused on insomnia, stress and cannabis use explores cannabis as a sleep aid and a mechanism for stress relief. However, recent theoretical and empirical evidence suggests a dynamic interplay between insomnia, cannabis use and perceived stress, yet few longitudinal studies exist. Using a sample of 1105 post-9/11 veterans assessed over four time points across 12 months, we used latent difference score modelling to examine proportional change between insomnia, perceived stress and cannabis use. Results revealed a complex interplay between all three constructs. In particular, we show that higher prior levels of insomnia are associated with greater increases in perceived stress, and greater prior levels of stress are associated with greater increases in cannabis use. Perhaps more importantly, our results also point to cannabis use as a catalyst for greater increases in both stress and insomnia severity. Our results suggest there may be both benefits and costs of cannabis use among veterans. Specifically, for veterans who experience chronic sleep problems, perceived stress may become overwhelming, and the benefit of stress reduction from increased cannabis use may come at the cost of increasing insomnia symptomology., (© 2023 The Authors.

- Abstract
Background: In Colombia, the average age of first sexual intercourse is between 14 and 15, and it has one of the highest fertility rates among adolescents in Latin America, which reflects poor access to health services and a lack of knowledge about contraception. Some laws support comprehensive sex education as a learning process that families and schools should provide. The objective of this work was to assess the frequency of adequate knowledge and attitudes of acceptance towards contraception in students, their associated factors, sexual behaviours in sexually active students, and experiences with sex education., Methods: Mixed methods study consisting of an analytical cross-sectional study and a qualitative hermeneutic phenomenological study. The former included students who completed a questionnaire with sociodemographic variables, surveys on knowledge and attitudes toward contraception, and questions about sexual behaviour. Focus groups were used in the qualitative study to evaluate students' and parents' sex education experiences., Findings: 827 students were surveyed, of whom 52.3% had adequate knowledge about contraceptives and 80.1% had attitudes of acceptance. Talking with parents about sex education, receiving sex education, and being in the eleventh grade increased the likelihood of having adequate knowledge. Each year of age, being male, being a victim of forced displacement, and studying in a public school were associated with lower possibilities of attitudes of acceptance. Using condoms, compared to other contraceptives, was associated with less adequate knowledge and attitudes of acceptance (p < 0.05). Experiences with sex education, contraception, and sexual and reproductive rights were three emerging categories in the focus groups., Interpretation: In a group of Colombian high school students, half of them had adequate knowledge, eight out of 10 had attitudes of acceptance about contraception, and both were associated with having received sex education. Nevertheless, different types of barriers to sexual education were identified at home and in schools. The results will allow the generation of educational policies that modify the educational model as well as new strategies by health professionals to raise awareness about responsible sexuality., Funding: This project was financed by internal research of the Fundación Universitaria de Ciencias de la Salud-FUCS (DI-I-0392-20)., Competing Interests: None of the researchers declared any conflict of interest., (© 2024 Published by Elsevier Ltd.)

- Abstract
Objective: Military veterans who were injured in combat very often report pain along with co-occurring perceived stress and preexisting depressive disorder. The systems model of pain is a theoretical model suggesting that pain and perceived stress are bidirectionally associated at the within-person level, and associations are heightened among those with depressive disorder. However, the systems model of pain has not been adequately tested. Testing the systems model of pain could illuminate salient treatment targets for combat-injured veterans with pain and co-occurring psychological problems., Methods: The present study empirically tests the systems model of pain among a sample of combat-injured veterans ( N = 902) surveyed five times during an 18-month period. We used a multigroup, autoregressive latent trajectory with structured residual statistical model to test the within-person associations between pain and perceived stress and determine whether associations differ between veterans with and without a positive screen for depressive disorder., Results: In line with the systems model of pain, pain and perceived stress were bidirectionally associated only among combat-injured veterans with depressive disorder. Among such veterans, perceived stress was positively associated with subsequent pain ( b = 0.12; 95% confidence interval = 0.06-0.17), and pain was positively associated with subsequent perceived stress ( b = 0.44; 95% CI = 0.11-0.77)., Conclusions: Our work highlights the interplay between pain and its psychological correlates among a particularly at-risk population. Clinicians addressing pain and perceived stress among combat-injured veterans should be prepared to identify and address depressive disorder., (Copyright © 2023 by the American Psychosomatic Society.)

- Abstract
The pulmonary manifestations of Systemic Lupus Erythematosus (SLE) in pediatric patients are poorly understood and the pulmonary manifestations reported from the adult population are generally extrapolated to the pediatric population. In the present work, the review of 228 files was carried out, in which the pulmonary manifestations, symptoms and antibody levels of the patients treated at the Hospital Regional de Alta Especialidad de Ixtapaluca (HRAEI), State of Mexico, Mexico, were identified. Statistical significance between groups was estimated using the Chi-square and Mann-Whitney U test. The main pulmonary manifestations identified were pleurisy (14 %), pulmonary hemorrhage (3.9 %), pulmonary thromboembolism (0.9 %), acute lupus pneumonitis (0.4 %), pulmonary arterial hypertension (0.4 %), and small lung syndrome (0.4 %). While the initial symptomatology was dyspnea with an incidence of 9.6 %, the mean oxygen saturation in the population was 96.87 %. Pleural effusion was identified as the most frequent pulmonary manifestation in radiographic changes. No statistically significant difference was found in antibody levels when comparing the groups. The most common pulmonary manifestation associated with SLE is pleurisy, however, the range of pulmonary manifestations in this type of patient can be very varied, as well as the presentation of each of them., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2023 The Authors.

- Abstract
Background: Phase III clinical trials have documented the efficacy of the SARS-CoV-2 vaccines in preventing symptomatic COVID-19. Nonetheless, it is imperative to continue analyzing the clinical response to different vaccines in real-life studies. Our objective was to evaluate the effectiveness of five different vaccines in hospitalized patients with COVID-19 during the third COVID-19 outbreak in Mexico dominated by the Delta variant., Methods: A test-negative case-control study was performed in nine tertiary-care hospitals for COVID-19. We estimated odds ratios (OR) adjusted by variables related a priori with the likelihood of SARS-CoV-2 infection and its severity., Results: We studied 761 subjects, 371 cases, and 390 controls with a mean age of 53 years (SD, 17 years). Overall, 51% had a complete vaccination scheme, and an incomplete scheme (one dose from a scheme of two), 14%. After adjustment for age, gender, obesity, and diabetes mellitus, we found that the effectiveness of avoiding a SARS-CoV-2 infection when hospitalized with at least one vaccination dose was 71% (OR 0.29, 95% CI 0.19-0.45), that of an incomplete vaccination scheme, 67% (OR 0.33, 95% CI 0.18-0.62), and that of any complete vaccination scheme, 73% (OR 0.27, 95% CI 0.17-0.43)., Conclusions: The SARS-CoV-2 vaccination program showed effectiveness in preventing SARS-CoV-2 infection in hospitalized patients during a Delta variant outbreak.

- Abstract
Purpose: To evaluate inflammatory response in critical bone injuries after implantation of the biomaterial composed of hydroxyapatite (HA)/poly (lactic-coglycolic acid) (PLGA)/BLEED., Methods: Forty-eight male Wistar rats (280 ± 20 grams) were divided into two groups: control group (CG), in which the animals do not receive any type of treatment; and biomaterial group (BG), in which the animals received the HA/PLGA/BLEED scaffold. Critical bone injury was induced in the medial region of the skull calotte with the aid of a trephine drill 8 mm in diameter. The biomaterial was implanted in the form of 1.5-mm thick scaffolds. Serum and calotte were collected at one, three and seven days., Results: Biomaterial had a significant effect on the morphological structure of the bone, accelerating osteoblast activation within three days, without causing exacerbated systemic inflammation. In addition, quantitative real-time polymerase chain reaction (qRT-PCR) analysis showed that BG induced upregulation of osteogenic genes such as runt-related transcription factor 2, and stimulated genes of inflammatory pathways such as tumor necrosis factor-α, on the first day without overexpressing genes related to bone matrix degradation, such as tissue inhibitor of metalloproteinases-1 and matrix metalloproteinase-9., Conclusions: The HA/PLGA/BLEED® association can be used as a bone graft to aid bone repair, as it is capable of modulating expression of important genes at this stage of the repair process.

- Abstract
HIV-associated hemophagocytic lymphohistiocytosis (HLH) is mainly due to infections caused by viruses, fungi, and, to a lesser extent, bacteria, often with fatal results. Case presentation: A 15-year-old pediatric patient from another institution was admitted to our hospital with a fever of unknown origin (FUO). Clinical analysis and laboratory studies diagnosed HIV infection. The approach to an FUO in a patient with AIDS is much more complex due to the search for common etiologies and opportunistic infections. In this case, disseminated histoplasmosis, pulmonary tuberculosis, pneumocystosis, and ehrlichiosis were diagnosed, prompting an urgent and comprehensive approach to prevent mortality. Due to the multiple infections, HLH was triggered. An early intervention with trimethoprim (TMP)-sulfamethoxazole (SMX), liposomal amphotericin B, doxycycline, and quadruple antiphimic therapy to suppress infections, in conjunction with the early administration of HLH treatment, favored the survival of this patient.

- Abstract
Background: U.S. veterans report high rates of traumatic experiences and mental health symptomology [e.g. posttraumatic stress disorder (PTSD)]. The stress sensitization hypothesis posits experiences of adversity sensitize individuals to stress reactions which can lead to greater psychiatric problems. We extend this hypothesis by exploring how multiple adversities such as early childhood adversity, combat-related trauma, and military sexual trauma related to heterogeneity in stress over time and, subsequently, greater risk for PTSD., Methods: 1230 veterans were recruited for an observational, longitudinal study. Veterans responded to questionnaires on PTSD, stress, and traumatic experiences five times over an 18-month study period. We used latent transition analysis to understand how heterogeneity in adverse experiences is related to transition into stress trajectory classes. We also explored how transition patterns related to PTSD symptomology., Results: Across all models, we found support for stress sensitization. In general, combat trauma in combinations with other types of adverse experiences, namely early childhood adversity and military sexual trauma, imposed a greater probability of transitioning into higher risk stress profiles. We also showed differential effects of early childhood and military-specific adversity on PTSD symptomology., Conclusion: The present study rigorously integrates both military-specific and early life adversity into analysis on stress sensitivity, and is the first to examine how sensitivity might affect trajectories of stress over time. Our study provides a nuanced, and specific, look at who is risk for sensitization to stress based on previous traumatic experiences as well as what transition patterns are associated with greater PTSD symptomology.

- Abstract
Despite affecting nearly 3% of active-duty service members, little is known about how LGBT-related stress experiences may relate to health outcomes. Thus, the present study sought to create a Military Minority Stress Scale and assess its initial reliability and construct validity in a cross-sectional study of active-duty LGBT service members ( N = 248). Associations between 47 candidate items and health outcomes of interest were analyzed to retain those with substantial betas. Item response theory analyzes, reliability testing, invariance testing, and exploratory factor analysis were performed. Construct validity of the final measure was assessed through associations between the sum score of the final measure and the health outcomes. The final 13-item measure demonstrated an excellent reliability ( ω = 0.95). Bivariate linear regressions showed significant associations between the sum score of the measure and overall health (β = -0.26, p < 0.001), overall mental health (β = -0.34, p < 0.001), physical health (β = 0.45, p < 0.001), life satisfaction (β = -0.24, p < 0.001), anxiety (β = 0.34, p < 0.001), depressive symptoms (β = 0.37, p < 0.001), suicidality (β = 0.26, p < 0.001), and PTSD (β = 0.42, p < 0.001), respectively. This study provides the first evidence that minority stressors in the military setting can be operationalized and measured. They appear to have a role in the health of LGBT service members and may explain the continued health disparities experienced by this population. Little is known regarding the experiences of LGBT active-duty service members, including experiences of discrimination. Understanding these experiences and their associated health outcomes during military service may therefore help and guide further etiological studies and intervention development.

- Abstract
The influence of black carbon nanoparticles on J774.A1 murine cells was investigated with the objective of exploring the cytotoxicity of black carbon functionalized with ethylenediamine CB-EDA. The results showed that CB-EDA has a cytotoxic profile for J774.A1 macrophages in a time- and dose-dependent manner. When phagocytosed by the macrophage, CB-EDA triggers a mechanism that leads to apoptosis. In this process, there is an increase in oxidative stress pathways due to the activation of nitric oxide and then ROS. This causes an imbalance in redox function and a disruption of membrane integrity that occurs due to high levels of LDH, in addition to favoring the release of the pro-inflammatory cytokines IL-6, IL-12, and tumor necrosis factor (TNF) in an attempt to modulate the cell. However, these stimuli are not sufficient to repair the cell and the level of mitochondrial integrity is affected, causing a decrease in cell viability. This mechanism may be correlated with the activation of the caspasse-3 pathway, which, when compromised, cleaves and induces cells death via apoptosis, either through early or late apoptosis. In view of this, the potential for cell damage was investigated by analyzing the oxidative and inflammatory profile in the macrophage lineage J774.A1 and identifying potential mechanisms and metabolic pathways connected to these processes when cells were exposed to NP CB-EDA for both 24 h and 48 h.

- Abstract
Breast cancer resistance protein (BCRP, ABCG2) is an efflux transporter that plays a crucial role in multidrug resistance to antineoplastic drugs. Ko143, an analogue of the natural product fumitremorgin C, is a potent inhibitor of ABCG2 but is rapidly hydrolyzed to an inactive metabolite in vivo . To identify ABCG2 inhibitors with improved metabolic stability, we have assessed a series of Ko143 analogues for their ability to inhibit ABCG2-mediated transport in ABCG2 -transduced MDCK II cells and determined the stability of the most potent compounds in liver microsomes. The most promising analogues were evaluated in vivo by positron emission tomography. In vitro , three of the tested analogues were potent ABCG2 inhibitors and stable in microsomes. In vivo , they increased the distribution of the ABCG2/ABCB1 substrate [
11 C]tariquidar to the brain both in wild-type (with Abcb1a/b transport blocked by tariquidar) and Abcb1a/b(-/-) mice. One analogue was more potent than Ko143 in both animal models.- Published

- Abstract
Current practices for structure analysis of extremely large molecular weight polysaccharides via solution-state NMR spectroscopy incorporate partial depolymerization protocols that enable polysaccharide solubilization in suitable solvents. Non-specific depolymerization techniques utilized for glycosidic bond cleavage, such as chemical degradation or ultrasonication, potentially generate structure fragments that can complicate the complete characterization of polysaccharide structures. Utilization of appropriate enzymes for polysaccharide degradation, on the other hand, requires prior structure information and optimal enzyme activity conditions that are not available to the analyst working with novel or unknown compounds. Herein, we describe the application of a permethylation strategy that allows the complete dissolution of the intact polysaccharides for NMR structure characterization. This approach is utilized for NMR analysis of Xylella fastidiosa EPS, which is essential for the virulence the plant pathogen that affects multiple commercial crops and is responsible for multibillion dollar losses each year.

- Abstract
We introduce the consideration of human migration into research on economic losses from extreme weather disasters. Taking a comparative case study approach and using data from the Federal Reserve Bank of New York/Equifax Consumer Credit Panel, we document the size of economic losses attributable to migration from 23 disaster-affected areas in the United States before, during, and after some of the most costly hurricanes, tornadoes, and wildfires on record. We then employ demographic standardization and decomposition to determine if these losses primarily reflect changes in out-migration or the economic resources that migrants take with them. Finally, we consider the implications of these losses for changing spatial inequality in the United States. While disaster-affected areas and their populations differ in their experiences of and responses to extreme weather disasters, we generally find that, relative to the year before an extreme weather disaster, economic losses via migration from disaster-affected areas increase the year of and after the disaster, these changes primarily reflect changes in out-migration (vs. the economic resources that migrants take with them), and these losses briefly disrupt the status quo by temporarily reducing spatial inequality., (Copyright © 2023 The Authors.)

- Abstract
Introduction: The US Military is experiencing a rise in HIV infections among gay and bisexual men (GBM) serving on active duty, yet little is known about this population's uptake of pre-exposure prophylaxis (PrEP), an evidence-based intervention for HIV prevention. This mixed methods study examines the facilitators and barriers to PrEP access and uptake among active duty GBM., Methods: Active duty GBM were recruited using respondent-driven sampling (2017 and 2018). Participants ( n = 93) answered quantitative survey questions on PrEP interest and accessibility. Another set of participants ( n = 10) discussed their PrEP experiences in qualitative interviews . We conducted descriptive and bivariate analyses of quantitative data, while qualitative data were analyzed using structural and descriptive coding techniques., Results: Approximately 71% of active duty GBM indicated interest in accessing PrEP. A greater proportion of those who disclosed (vs. did not disclose) their sexual orientation to their military doctor discussed ( p < 0.001) or accessed ( p = 0.017) PrEP. The following qualitative themes emerged: (1) providers' negative views and knowledge gaps related to PrEP; (2) lack of a systems approach to PrEP access; (3) confidentiality concerns; and (4) reliance on peer networks for PrEP guidance and support., Conclusions: Study results indicate that active duty GBM are interested in and want to discuss PrEP with their military doctors, but gaps in providers' PrEP-related knowledge and skills, as well as mistrust in the military health care system, remain., Policy Implications: A system-wide approach that addresses confidentiality concerns and removes procedural barriers to PrEP access is recommended to improve PrEP uptake in this population., Competing Interests: Competing InterestsThe authors declare no competing interests., (© The Author(s) 2021.)

- Abstract
Many military veterans face significant challenges in civilian reintegration that can lead to troublesome behavior. Drawing on military transition theory (MTT) and using data from a survey of post-9/11 veterans in two metropolitan areas ( n = 783), we investigate previously unexamined relationships between post-discharge strains, resentment, depression, and risky behavior, taking into account a set of control variables, including combat exposure. Results indicated that unmet needs at time of discharge and perceived loss of military identity are associated with increased risky behavior. Much of the effects of unmet discharge needs and loss of military identity are mediated by depression and resentment toward civilians. The results of the study are consistent with insights from MTT, providing evidence of specific ways in which transitions can affect behavioral outcomes. Moreover, the findings highlight the importance of helping veterans meet their post-discharge needs and adapt to changing identity, in order to reduce the risk of emotional and behavioral problems.

- Abstract
American veterans are a population that suffer from both context specific stressors as well as many population-specific major-life events. The present exploratory study utilises a longitudinal cohort of 1230 U.S. veterans surveyed from February 2020 through February 2021. We sought to understand heterogeneity in perceived stress, using growth mixture modelling, over this time period, how COVID-specific factors such as negative reactions to the pandemic, loneliness, and employment disruptions influence perceived stress trajectories, and how veterans vary across distal outcomes including posttraumatic stress disorder (PTSD), pain, depression, sleep problems, physical health, and alcohol use disorder. Results revealed a 4-class solution: Stable High, Stable Low, Steady Increasing, and Steady Decreasing classes. In terms of COVID specific factors, negative reactions to COVID were consistently associated with perceived stress for those in the Stable High and Steady Increasing classes whereas loneliness was associated with stress trajectories for all emergent classes. Finally, in terms of our distal outcomes, results showed a relatively robust pattern with veterans in the Stable High or Steady Increasing classes reporting worse scores across all outcomes including PTSD, pain, sleep problems, physical health, depression, and alcohol use disorder. Understanding the interplay between existing vulnerabilities, ongoing stressors, and behavioural health outcomes among veterans is crucial for prevention and intervention efforts., (© 2022 John Wiley & Sons Ltd.)

- Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) cytotoxicity may involve inhibition of peroxisome proliferator-activated receptor alpha. Fenofibrate activates peroxisome proliferator-activated receptor alpha and inhibits SARS-CoV-2 replication in vitro. Whether fenofibrate can be used to treat coronavirus disease 2019 (COVID-19) infection in humans remains unknown. Here, we randomly assigned inpatients and outpatients with COVID-19 within 14 d of symptom onset to 145 mg of oral fenofibrate nanocrystal formulation versus placebo for 10 d, in a double-blinded fashion. The primary endpoint was a severity score whereby participants were ranked across hierarchical tiers incorporating time to death, mechanical ventilation duration, oxygenation, hospitalization and symptom severity and duration. In total, 701 participants were randomized to fenofibrate (n = 351) or placebo (n = 350). The mean age of participants was 49 ± 16 years, 330 (47%) were female, mean body mass index was 28 ± 6 kg/m
2 and 102 (15%) had diabetes. Death occurred in 41 participants. Compared with placebo, fenofibrate had no effect on the primary endpoint. The median (interquartile range) rank in the placebo arm was 347 (172, 453) versus 345 (175, 453) in the fenofibrate arm (P = 0.819). There was no difference in secondary and exploratory endpoints, including all-cause death, across arms. There were 61 (17%) adverse events in the placebo arm compared with 46 (13%) in the fenofibrate arm, with slightly higher incidence of gastrointestinal side effects in the fenofibrate group. Overall, among patients with COVID-19, fenofibrate has no significant effect on various clinically relevant outcomes ( NCT04517396 )., (© 2022.

- Abstract
Purpose: To assess, in a cohort of patients with rheumatoid arthritis (RA) treated with subcutaneous antitumor necrosis factor drugs (anti-TNFs), the levels of treatment adherence before and after implementing a comprehensive care model (CCM)., Patients and Methods: An observational study including RA patients under treatment with subcutaneous anti-TNFs (adalimumab, etanercept, and golimumab) selected at convenience was performed; a sample size of 125 patients was calculated. The outcome variable was adherence assessed with the Compliance Questionnaire on Rheumatology (CQR19), measured before and after implementing a CCM. Descriptive and bivariate analyses were performed comparing adherence before and after applying the model (Wilcoxon and McNemar's Chi
2 test). For multivariate analysis, a generalized linear model adjusted for covariates was performed, where the difference in the proportion of adherence was the outcome measure., Results: A total of 131 RA patients were followed-up for 24 months; average age was 62 years, and 83.9% were women. The median of DAS28 at the beginning of the follow-up was 2.32, and the HAQ was 0.25. At baseline, 87.8% were adherent; after 24 months, 96.2% were adherent according to CQR19. At the end of follow-up, adherence increased with the three types of anti-TNFs treatment. In a matched model adjusted for clinical variables, the CCM was estimated to produce a 9.4% increase in the total percentage of adherent patients. Additionally, a statistically significant increase of 4.5% in the percentage of adherent patients treated with golimumab compared with etanercept and adalimumab was found., Conclusion: A CCM produced an important increase in the percentage of patients with rheumatoid arthritis adherent to treatment after 24 months of follow-up. It is noteworthy that Golimumab patients were more adherent when compared with other current anti-TNFs treatments., Competing Interests: PSM has received fees for conferences, counseling, advisory boards, and travel to academic meetings expenses and research grants in the last 5 years from Janssen, AbbVie, Biopass-UCB, Bristol, Lilly, Pfizer, Roche, Tecnofarma, and Sanofi.

- Abstract
COVID-19-associated pulmonary aspergillosis (CAPA) has had a high incidence. In addition, it has been associated with prolonged hospital stays, as well as several predisposing risk factors, such as fungal factors (nosocomial organism, the size of the conidia, and the ability of the Aspergillus spp. of colonizing the respiratory tract), environmental factors (remodeling in hospitals, use of air conditioning and negative pressure in intensive care units), comorbidities, and immunosuppressive therapies. In addition to these factors, SARS-CoV-2 per se is associated with significant dysfunction of the patient's immune system, involving both innate and acquired immunity, with reduced CD4+ and CD8+ T cell counts and cytokine storm. Therefore, this review aims to identify the factors influencing the fungus so that coinfection with SARS-CoV-2 can occur. In addition, we analyze the predisposing factors in the fungus, host, and the immune response alteration due to the pathogenicity of SARS-CoV-2 that causes the development of CAPA.

- Abstract
Background: The formation of foam cells occurs due to the increase in low-density plasma lipoprotein (LDL) and dysregulation of inflammation, which is important for the development of atherosclerosis., Objective: To evaluate the profile of tumor necrosis factor-alpha (TNF-α) and Interleukin-6 (IL-6) in the existing foam cell formation method, optimizing this protocol., Methods: The LDL was isolated, oxidized, and labeled with a Fluorescein isothiocyanate (FITC) probe. Foam cells were generated from THP-1 human monocyte-derived cells and incubated in the absence (control) or presence of FITC-ox-LDL (10, 50, 100, 150, or 200 μg/mL), for 12, 24, 48, or 72 hours. The accumulated FITC-ox-LDL in the cell was quantified by microscopy. The enzyme-linked immunosorbent assay was evaluated to quantify the IL-6 and TNF-α, with p < 0.05 considered significant., Results: All the FITC-ox-LDL concentrations tested showed a higher fluorescence when compared to the control, showing a greater accumulation of lipoprotein in cells. The higher the concentration of FITC-ox-LDL, the greater the production of TNF-α and IL-6. The production of IL-6 by foam cells was detected up to the value of 150 µg/mL of the maximum stimulus for LDL. Concentrations above 50 μg/mL LDL stimulated greater release of TNF-α compared to control., Conclusions: Our model contributes to the understanding of the release of IL-6 and TNF-α in response to different concentrations of ox-LDL, using an optimized method for the formation of foam cells.

- Abstract
U.S. veterans are at risk for insomnia, which often co-occurs with symptoms of posttraumatic stress disorder (PTSD) and alcohol use. Much of the research on veterans and these three constructs is cross-sectional and focused on unidirectional pathways. Recent theoretical and empirical evidence suggests a dynamic interplay between insomnia, PTSD, and alcohol use, yet few longitudinal studies exist. A clearer understanding of these pathways is needed to help inform integrated treatments. Using a sample of 1,230 post-9/11 veterans assessed over four time points across 12 months, we used a latent difference score modeling approach to examine proportional and dynamic change between insomnia, PTSD, and alcohol. Results revealed a complex interplay between all three constructs. Higher prior levels of both PTSD and alcohol use were associated with greater subsequent changes in insomnia symptoms (i.e., worse sleep). Moreover, although veterans drank less frequently as their insomnia symptoms worsened over time, greater changes in insomnia symptoms (i.e., worse symptoms) was a mechanism linking PTSD and more frequent drinking. As the research on interventions addressing insomnia, PTSD, and alcohol is limited, there are opportunities for researchers and clinicians to develop programs that effectively target all three in integrated treatments., (Copyright © 2022 Elsevier Ltd.

- Abstract
Moral injury has emerged as a topic of significant research and clinical interest over the last decade. However, much work remains to be done to comprehensively define the moral injury construct, with implications for understanding the etiology and maintenance of moral injury, its symptoms, associations with and distinctions from traumatic illness, and treatment approaches. We provide a brief overview of the existing moral injury literature and introduce a novel dual process model (DPM) of moral injury and traumatic illness. The DPM posits an event exposure which may satisfy DSM-5 posttraumatic stress disorder (PTSD) criterion A, potential morally injurious event (PMIE) criteria, or both, followed by individual role appraisal as a perpetrator through action or inaction, a witness, a victim, or a combination of the these. Role appraisal influences symptoms and processes across biological, psychological, behavioral, social, spiritual/religious, as well as values, character, and identity domains to support a label of traumatic illness, moral injury, or both. The DPM provides a flexible analytical framework for evaluating symptoms associated with moral injury and traumatic stress and has important implications for treatment. The most thoroughly reviewed evidence-based interventions for traumatic stress hinge on exposure and habituation mechanisms to manage dysregulation of fear and memory systems, but these mechanisms often do not address core domains of moral injury identified in the DPM, including spiritual, religious, values, character, and identity domains as these exist largely outside of the putative fear network. We provide brief vignettes to illustrate the practical application of the DPM and argue that adjunct and stand-alone approaches which address values and character domains, leveraging principles of Stoicism, non-judgment of experience, acceptance, and values-oriented action, are more likely than traditional trauma treatment approaches to positively affect moral injury symptoms., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Barr, Atuel, Saba and Castro.)

- Abstract
Among American veterans, the behavioral health impact of potentially morally injurious experiences (PMIEs) has recently garnered attention. There is heterogeneity in the types of experiences that are classified as PMIEs, and different PMIEs may be differentially associated with various outcomes. We aimed to explore heterogeneity in PMIEs among veterans, and whether PMIE classes are differentially associated with several behavioral health outcomes (i.e., symptoms of posttraumatic stress disorder, depression, anxiety, and anger). Data were from a survey study of veteran health attitudes and behavior (N=1004). We employed a Latent Class Analysis approach to identify sub-groups of participants with similar PMIE response patterns on the Moral Injury Events Scale and to determine the relationship between class membership and behavioral health outcomes. A 4-class solution best fit our data, with classes including (1) high all, (2) witnessed transgressions, (3) troubled by failure to act, and (4) moderate all. There was a link between class membership and behavioral health, with the high all class and moderate all classes consistently reporting especially poor outcomes. Our results are in line with cumulative stress models suggesting exposure to multiple forms of adversity may place individuals at particular risk of poor health and functioning. Clinicians working with veterans should screen for exposure to the full range of PMIE types and be prepared to address the multitude of behavioral health impacts., (Copyright © 2022 Elsevier Ltd.

- Abstract
Background: While many health care providers have shifted toward telehealth services in response to the COVID-19 pandemic, little is known about the perception and acceptance of such services, particularly among vulnerable populations. Veterans, who are at increased risk of physical and mental health needs, may benefit from the use and availability of telehealth services. Materials and Methods: Cross sectional survey data related to telehealth use, satisfaction, and access were collected through an online survey. Participants from previous research studies and veterans receiving care at a national veteran behavioral health organization were invited to participate. Results: A total of 404 veterans participated. Before the pandemic, many veterans had never used telehealth for physical (72%) or mental (76%) health care. Since the start of the pandemic, 62% of participants reported they received some care through telehealth services. Most participants found telehealth valuable and helpful (82%), indicated the technology was well explained (77%), and felt that issues were resolved quickly and easily (67%). Access to care was limited among participants who utilize massage therapy (64%), dental care (53%), routine checkups (50%), acupuncture (50%), and physical therapy (48%). Discussion: These findings showed an increase in the use of telehealth services and overwhelming satisfaction among veterans. Despite this, some veterans indicated barriers to receiving physical and mental health care. Conclusions: This provides an opportunity to expand the use of telehealth services to meet the health care needs of veterans. Barriers to care should be addressed to minimize the impact on the well-being of veterans.

- Abstract
Prior research among military personnel has indicated that sexual harassment, stalking, and sexual assault during military service are related to negative health sequelae. However, research specific to LGBT U.S. service members is limited. The current study aimed to explore the health, service utilization, and service-related impact of stalking and sexual victimization experiences in a sample of active-duty LGBT U.S. service members ( N = 248). Respondent-driven sampling was used to recruit study participants. U.S. service members were eligible to participate if they were 18 years or older and active-duty members of the U.S. Army, U.S. Navy, U.S. Marine Corps, or U.S. Air Force. This study included a sizeable portion of transgender service members ( N = 58, 23.4%). Sociodemographic characteristics, characteristics of military service, health, and sexual and stalking victimization in the military were assessed. Regression was used to examine relationships between health and service outcomes and sexual and stalking victimization during military service. Final adjusted models showed that experiencing multiple forms of victimization in the military increased the odds of visiting a mental health clinician and having elevated somatic symptoms, posttraumatic stress disorder symptomatology, anxiety, and suicidality. Sexual and stalking victimization during U.S. military service was statistically significantly related to the mental and physical health of LGBT U.S. service members. Interventions to reduce victimization experiences and support LGBT U.S. service members who experience these types of violence are indicated. Research that examines the role of LGBT individuals' experiences and organizational and peer factors, including social support, leadership characteristics, and institutional policies in the United States military is needed.

- Abstract
Background: Multidisciplinary care (MDC) remains a cornerstone for breast cancer management as it is associated with improved quality of care and patient outcomes. However, the adoption of MDC practice is heterogeneous and has been poorly explored in Latin America. The objective was to describe barriers and possible facilitators for providing MDC to breast cancer patients in five Latin American countries., Methods: A panel of experts with an active clinical practice in Bolivia, Colombia, Ecuador, Mexico, and Uruguay was convened to identify barriers and facilitators to MDC. This study is a qualitative synthesis of a structured discussion regarding the state of MDC in the setting of breast cancer., Findings: Experts recognized that most oncology practices in Latin America do not apply a multidisciplinary approach for breast cancer patients. Predominant barriers for MDC are fragmentation of health services, being understaffed, inadequate infrastructure, and geographic disparities. Access to MDC varies widely in the region, with significant heterogeneity documented within countries. MDC practice was described as being more common in the private sector in Ecuador and Uruguay, while it is more widely implemented in public institutions of Colombia and Bolivia., Interpretation: Establishing quality MDC remains a challenge for oncology practices in Latin America. Addressing regional issues and identifying specific local needs is warranted to encourage the adoption of an effective multidisciplinary approach and, consequently, improve clinical outcomes. Active involvement of all stakeholders is required to build locally solutions and should involve institutions, health professionals, and patients., Funding: Research was funded by Productos Roche S.A., Competing Interests: Productos Roche S.A funded the research group activities, including design, data collection, and analysis, but they did not intervene and stay sidelines of the carried-out activities.

- Abstract
The U.S. Internal Revenue Service (IRS) makes publicly and freely available period migration data at the state and county levels. Among their uses, these data inform estimates of net-migration as part of the U.S. Census Bureau's Population Estimates Program, which, in turn, are used for producing other annual statistics, survey design, business and community planning, and federal funding allocations. Building on and extending prior research, we devote this Research Brief to documenting from multiple new angles a highly concerning and apparently systemic problem with the IRS migration data since the IRS took over responsibilities for preparing these data from the U.S. Census Bureau in 2011. As we then discuss, despite the fact that the IRS provides documentation detailing changes that it made to how it prepares these data relative to how the U.S. Census Bureau prepared them, it is not clear why or how these changes would result in the problem detailed in our analysis. Given that this problem appears to be an internal one within the IRS, we conclude by suggesting that the post 2011-12 IRS migration data not be used until this problem is resolved, and we encourage the IRS to do so quickly, transparently, and collaboratively.

- Abstract
Infertility is a common disease that impacts 15% of reproductive age couples worldwide, and genetic causes are implicated in about half of those cases. Non-obstructive azoospermia is a severe form of male infertility that features spermatogenic failure resulting in no sperm in the ejaculate and severely reduces the chance to have biological children. We created a Tex11_1260Ins(TT) (1260GATA → TTGGTA) mutant mouse that models the Tex11_1258(TT) mutation identified from a patient with nonobstructive azoospermia. The Tex11_1260Ins(TT) iPSC cells displayed characteristics of pluripotent-like morphology, expressed pluripotent protein markers, show normal karyotype, and can to differentiate into tissues of the three germ layers., (Copyright © 2022 The Author(s).

- Abstract
Background: The transition from military to civilian life is a dramatic change that is often stressful for veterans. However, little is known regarding how mental health symptoms fluctuate in the period leading up to and following separation from the military., Methods: The current study examined posttraumatic stress disorder and depression symptoms reported on surveys completed within 1 year of military separation from 23,887 active duty Millennium Cohort Study participants. A series of general linear models and graphs stratified by demographic and military characteristics examined the association between time until/since separation and mental health symptoms., Results: Character of discharge had the most striking relationship between time until/since separation and mental health. Personnel with Honorable discharges did not differ in their level of mental health symptoms across the study period. In contrast, personnel with Other than Honorable/General discharges reported normal levels of mental health symptoms 1 year-prior to separation but reported progressively greater symptoms leading to separation which persisted through the remainder of study period., Conclusions: This study suggests that additional outreach is needed for personnel with Other than Honorable/General discharges. However, for most other personnel, increased mental health symptomatology around military separation is not a normative phenomenon and any instance should be treated promptly., (© 2022 The Authors.

- Abstract
The objective of this work was to use the random amplification of the polymorphic DNA-polymerase chain reaction (RAPD-PCR) technique to select polymorphic patterns through qualitative and quantitative analyses to differentiate the species A. flavus , A. fumigatus , A. niger and A. tubingensis . Twenty-seven Aspergillus isolates from different species were typified using phenotypic (macro- and micromorphology) and genotypic (partial BenA gene sequencing) methods. Thirty-four primers were used to obtain polymorphic patterns, and with these a qualitative analysis was performed to select the primers that presented species-specific patterns to distinguish each species. For the quantitative selection, a database was built from the polymorphic patterns and used for the construction of logistic regression models; later, the model that presented the highest value of sensitivity against specificity was evaluated through ROC curves. The qualitative selection showed that the primers OPA-19, P54, 1253 and OPA-02 could differentiate the species. A quantitative analysis was carried out through logistic regression, whereby a species-specific correlation of sensitivity and specificity greater than 90% was obtained for the primers: OPC-06 with a 96.32% match to A. flavus ; OPF-01 with a 100% match to A. fumigatus ; OPG-13 with a 98.01% match to A. tubingensis; and OPF-07 with a 99.71% match to A. niger . The primer OPF-01 discriminated the four species as well as closely related species. The quantitative methods using the selected primers allowed discrimination between species and showed their usefulness for genotyping some of the species of medical relevance belonging to the genus Aspergillus .

- Abstract
Background: Alcohol use disorder (AUD) is prevalent among Operation Enduring Freedom, Operation Iraqi Freedom, and Operation New Dawn (OEF/OIF/OND) veterans. Pain and posttraumatic stress disorder (PTSD) are highly comorbid and increase risk of AUD. Prior studies linking pain or PTSD to AUD have not explored interactions between pain and PTSD symptoms., Methods: OEF/OIF/OND veterans (N = 1230) were recruited from social media websites for a cross-sectional study of health behavior. Pain was assessed using the Pain Outcomes Questionnaire. PTSD symptoms and PTSD symptom clusters were assessed using the Posttraumatic Stress Disorder Checklist for DSM-5. AUD symptoms were assessed with the AUD Identification Test. Linear regression models were used to test for main and interaction effects in the full sample and separately by sex., Results: Both pain and PTSD symptoms were associated with increased AUD symptomology, though the relationship between pain and AUD was heighted at relatively low PTSD symptoms. With respect to PTSD symptom clusters, re-experiencing and negative cognitions and mood were associated with increased AUD symptomology. Interactions between pain and re-experiencing as well as pain and avoidance were revealed. Results for men mirrored the full sample, while an interaction between pain and negative cognitions and mood was associated with AUD in women., Conclusions: Results highlight associations between AUD, PTSD symptoms, and pain among veterans. While the relationship between pain and AUD appeared stronger in the context of low PTSD symptoms, both pain and PTSD symptoms were associated with increased AUD. Clinicians treating veterans with AUD should address the range of potential comorbidities., (Copyright © 2021 Elsevier Ltd. All rights reserved.)

- Abstract
Stalking is associated with mental health concerns, although little is known about the influence of stalking and mental health concerns among veterans. This study evaluated stalking experienced during military service in two community-based, nonclinical samples of veterans ( N = 1,980). Models explored (a) types of stalking, (b) characteristics of veterans who experienced stalking, and (c) the associations between stalking with posttraumatic stress disorder (PTSD) and depression. Types of stalking varied by sex; female veterans were significantly more likely to experience stalking than male veterans (58.5% vs. 34.6%, p < .001, respectively). Female veterans reported unwanted messages, emails, or phone calls (37.2%), and male veterans experienced someone showing up unannounced or uninvited (23.5%) most frequently. Stalking experiences also differed by age with female and male veterans 18 to 39 years old significantly more likely to have experienced stalking ( p < .001 and p < .001, respectively) than veterans over age 40. Associations between prior stalking experiences and mental distress were found for both female and male veterans. Both female and male veterans who experienced stalking were significantly more likely to have probable PTSD (odds ratio [OR] = 1.88, 95% confidence interval [CI] = [1.04, 3.39] and OR = 3.08, 95% CI = [2.27, 4.18], respectively) and depression (OR = 2.54, 95% CI = [1.38, 4.58] and OR = 2.78, 95% CI = [2.05, 3.79], respectively). These findings highlight (a) the rates of stalking experienced during military service, (b) the need for assessment of stalking to inform treatment, and (c) lay the foundation for the Department of Defense (DoD) to further evaluate stalking among military populations.
