Abstract
Floods are increasing in frequency and may increase the risk for experiencing emotional distress, anxiety, depression and PTSD. The aim of this study was to determine the extent of damage, loss, injury and death resulting from floods that occurred in and around the city of Durban, South Africa, in April 2022, and associated changes in mental health pre- to post-floods in a low-income setting. Seventy-three women between the ages of 18 and 45, residing in flood affected, low-income settings, were interviewed prior to the floods occurring. Mental health measures were repeated with 69 of the 73 women during the post-flood interview along with a questionnaire measuring flood-related exposures. Loss of infrastructure (lacked access to drinking water, electricity, fresh food, could not travel to work, had to stay in a shelter and could not get hold of friends or family) was a predictor of post-flood change in levels of emotional distress and anxiety. Higher levels of prior trauma exposure were associated with higher post-flood levels of emotional distress. Higher pre-flood food insecurity was also associated with higher post-flood anxiety. Women affected by poverty, food insecurity and a history of trauma are vulnerable to the additive adverse mental health effects of floods. Proactive approaches to diminishing the impact of floods on the livelihood of women is needed and post-flood relieve efforts may be more affective if they are enhanced by providing mental health support.

Abstract
BACKGROUND More than 50,000 older male veterans incarcerated in prisons are expected to return to their communities and utilize the Veterans Health Administration (VHA) and community healthcare systems. To support the continuity of healthcare and overall successful community reentry of older incarcerated veterans, an understanding of their health profiles and treatment utilization while in correctional care is needed. OBJECTIVE To assess the health status of older male veterans incarcerated in state prisons and explore demographic, military, and VHA-related factors associated with medical conditions, disabilities, behavioral conditions, and medical and behavioral treatment utilization. DESIGN/PARTICIPANTS Cross-sectional observational study of 880 male veterans aged 50 + incarcerated in state prisons using data from the 2016 Bureau of Justice Statistics Survey of Prison Inmates. MAIN MEASURES Veteran status, self-report health status, and treatment utilization since prison admission. Prevalence rates for conditions and treatment utilization were calculated. Logistic regression models were used to examine the association of characteristics with conditions and treatment utilization. KEY RESULTS Among the 880 older male veterans in state prisons, the majority reported having a current medical condition (79.3%) or disability (61.6%), almost half had history of a mental health condition (44.5%), and more than a quarter (29%) had a substance use disorder. Compared to White veterans, Black veterans were less likely to report a disability or mental health condition. Few demographic, military, and VA-related characteristics were associated with medical or behavioral conditions or treatment utilization. CONCLUSION Our results suggest that the VHA and community healthcare systems need to be prepared to address medical and disability conditions among the majority of older male veterans who will be leaving prison and returning to their communities. Integrated medical and behavioral healthcare delivery models may be especially important for these veterans as many did not receive behavioral health treatment while in prison.

Abstract
BACKGROUND Older veterans involved in the criminal legal system (CLS) may have patterns of multimorbidity that place them at risk for poor health outcomes. OBJECTIVES To estimate the prevalence of medical multimorbidity (≥2 chronic medical diseases), substance use disorders (SUDs), and mental illness among CLS-involved veterans aged 50 and older. RESEARCH DESIGN Using Veterans Health Administration health records, we estimated the prevalence of mental illness, SUD, medical multimorbidity, and the co-occurrence of these conditions among veterans by CLS involvement as indicated by Veterans Justice Programs encounters. Multivariable logistic regression models assessed the association between CLS involvement, the odds for each condition, and the co-occurrence of conditions. SUBJECTS Veterans aged 50 and older who received services at Veterans Health Administration facilities in 2019 (n=4,669,447). METHODS Mental illness, SUD, medical multimorbidity. RESULTS An estimated 0.5% (n=24,973) of veterans aged 50 and older had CLS involvement. For individual conditions, veterans with CLS involvement had a lower prevalence of medical multimorbidity compared with veterans without but had a higher prevalence of all mental illnesses and SUDs. After adjusting for demographic factors, CLS involvement remained associated with concurrent mental illness and SUD (adjusted odds ratio [aOR] 5.52, 95% CI=5.35-5.69), SUD and medical multimorbidity (aOR=2.09, 95% CI=2.04-2.15), mental illness and medical multimorbidity (aOR=1.04, 95% CI=1.01-1.06), and having all 3 simultaneously (aOR=2.42, 95% CI=2.35-2.49). CONCLUSIONS Older veterans involved in the CLS are at high risk for co-occurring mental illness, SUDs, and medical multimorbidity, all of which require appropriate care and treatment. Integrated care rather than disease-specific care is imperative for this population.

Abstract
PURPOSE The purpose of this study was to examine the literature surrounding dementia in the aging correctional population and assess the role of cognitive screening related to dementia detection within corrections. The literature regarding the role of dementia within the justice continuum is scant. Furthermore, correctional health researchers have not reached a consensus on the best age to administer cognitive screening in older persons or prioritizes a screening tool for the early detection of dementia. DESIGN/METHODOLOGY/APPROACH A key search term list including dementia screening and was developed to review the literature surrounding dementia and the aging correctional population. PubMed, Criminal Justice Abstracts (Ebsco) and the National Criminal Justice Reference Service were used within the academic search. A gray literature search using these same search terms was conducted reviewing criminal justice federal agencies and organizations for additional information on the dementia experience within correctional settings. Snowballing was used to capture relevant theoretical and empirical knowledge. FINDINGS Shortages in aging specialized health-care staffing presents a barrier for the clinical interpretation of Montreal Cognitive Assessment (MoCA) results. Correctional officers are also identified as useful candidates within the administration of cognitive screening with proper training. The MoCA may be the optimal cognitive screening tool for dementia, until an original cognitive screening tool is created specific to the correctional population. An age of 55 years or older may serve as the best cutoff score for classifying incarcerated individuals as older persons, and screening should be prioritized for these individuals. Finally, new specialized programs related to dementia within correctional settings are identified. RESEARCH LIMITATIONS/IMPLICATIONS A limitation of this research is the conflicting opinions among researchers regarding the use of general cognitive screening tools within the correctional setting. ORIGINALITY/VALUE This research can inform correctional organizational policy and practices regarding the screening of older persons suspected of dementia. Most notably, this research proposes that correctional settings should incorporate the MoCA within initial screening of all individuals 55 years of age or older, enriching the job design of correctional officer's job positions to include cognitive testing, and for correctional settings to provide dementia and age-associated training for correctional officers. Finally, this paper informs future research in the development of a cognitive assessment tool specific to the correctional population.

Abstract
Knowledge of bronchial artery anatomy, including the possible locations of anomalous origin, is essential for complete catheter directed embolization for massive hemoptysis. Undetected anomalous bronchial arteries can be a source of failed bronchial artery embolization. We report a case of a common trunk bronchial artery arising from the left vertebral artery and review standard and variant bronchial artery anatomy.

Abstract
This principle goal of this research was to examine the effects of various nanomaterials on the activity and behavior of the firefly enzyme luciferase. Nanomaterials have been found to stabilize, and in some instances, shown to increase the activity of enzymes. In this study gold, manganese oxide (MnO), and zinc oxide (ZnO) nanomaterials were utilized in order to test their effects on enzyme activity. Luciferase was used because its activity is easy to analyze, as it typically produces a large amount of bioluminescence easily detected by a Microtiter plate reader. Following incubation with the various nanomaterials, luciferase was subjected to degradation by several protein denaturing agents, such as heat, SDS, urea, ethanol, protease, hydrogen peroxide, and pH changes. Results indicated that luciferase activity is indeed affected when combined with nanomaterials, accompanied by both increases and decreases in enzyme activity depending on the type of nanomaterial and denaturing agent used. In most of the experiments, when incubated with ZnO nanomaterials, luciferase depicted significant increases in activity and bioluminescence. Additional experiments, in which human A375 cells were treated with luciferase-nanomaterial mixtures, also depicted increased enzyme activity and bioluminescence for luciferase incubated with ZnO nanomaterials. Ultimately, our findings indicated that when luciferase was subjected to multiple types of denaturation, zinc oxide nanomaterials dramatically preserved and increased enzyme activity and bioluminescence.

Abstract
The current research of our group focuses on delivery of oligonucleotides and gene vaccines targeted against infectious disease and cancer. Recently we reported a strategy for associating DNA to gold via protamine delivery enhancing material which here we suggest might be applicable to RNA and to other nanoparticles. An important new modality for such RNA based nanoparticles (RNPs) is the myriad of genes now known to undergo alternative splicing. Here we will review some important issues for the binding, stabilization and delivery of RNA, particularly splice-site switching oligomers (SSOs) via these RNPs in order to achieve selective molecular therapeutic effects and unlock their potential as chemotherapeutic agents.

Abstract
The use of electron tomography has allowed the three-dimensional membrane topography of the mitochondrion to be better understood. The most striking feature of this topology is the crista junction, a structure that may serve to divide functionally the inner membrane and intermembrane spaces. In situ these junctions seem to have a preferred size and shape independent of the source of the mitochondrion with few exceptions. When mitochondria are isolated and have a condensed matrix the crista junctions enlarge and become nondiscrete. Upon permeation of the inner membrane and subsequent swelling of the matrix space, the uniform circular nature of the crista junction reappears. We examine the distribution of shapes and sizes of crista junctions and suggest a thermodynamic model that explains the distribution based on current theories of bilayer membrane shapes. The theory of spontaneous curvature shows the circular junction to be a thermodynamically stable structure whose size and shape is influenced by the relative volume of the matrix. We conclude that the crista junction exists predominantly as a circular junction, with other shapes as exceptions made possible by specific characteristics of the lipid bilayer.

Abstract
Mycobacterial infection, including both tuberculosis and nontuberculous mycobacterial infection, is an important cause of morbidity and mortality in immunocompromised patients, particularly those who are infected with the human immunodeficiency virus. When these patients have active tuberculosis, apical, often cavitary, opacities characteristic of postprimary tuberculosis remain among the more common radiographic presentations. However, unusual radiographic manifestations of tuberculosis are more common in immunocompromised patients than in the general population. Nontuberculous mycobacterial infection in immunocompromised patients is frequently hematogenously disseminated, and the appearance on chest radiography is varied. Among patients infected with the human immunodeficiency virus, unifocal or multifocal alveolar infiltrates and mediastinal lymphadenopathy are the most common manifestations.

Abstract
Biodegradable microcapsules of zidovudine (AZT) were prepared using poly-(lactide/glycolide) by the solvent evaporation technique. The objective of this project was to focus on the effect of several formulation and processing factors on the efficiency of encapsulation, surface morphology, and drug release profiles. When the drug was incorporated as powder or as aqueous suspension containing a high amount of insoluble particles, to the organic phase the surface of the microcapsules was appeared to be wrinkled. The efficiency of encapsulation decreased when AZT powder was dispersed directly into the organic solvent instead of adding as an aqueous solution. When the relative volume of the aqueous phase containing 1% PVA was changed from 25 up to 125% of the volume of the organic phase, the efficiency of encapsulation, surface morphology, and release profiles did not change significantly. The efficiency of encapsulation decreased from 9 to 3.8% when the drug loading was increased from 10 to 50% of the weight of the polymer.

Abstract
PURPOSE To determine if primary testicular germ cell tumors that overexpress p53 tumor suppressor gene protein have p53 gene mutations. MATERIALS AND METHODS We examined 30 primary testicular tissues from 26 patients representing two groups. Group one consisted of eleven cases (6 nonseminomatous germ cell tumors and 5 seminomas) in which tissue samples for DNA analysis were microdissected from paraffin block regions with elevated immunohistochemical staining for p53 protein. Group two consisted of 19 testis tumor tissues which had been fresh frozen and were chosen to correspond to archival tissue specimens exhibiting elevated levels of p53 protein. The DNA was extracted from these tissues and subjected to exon specific amplification by polymerase chain reaction (PCR) and cold single-strand conformation polymorphism (Cold SSCP) analysis. RESULTS In these cases with elevated p53 protein, no p53 gene exon 5-8 mutations were detected except 1 seminoma with a codon 140 silent mutation (no protein alteration). CONCLUSIONS Testicular tumors appear to exhibit elevated levels of wild-type p53 protein, the significance of which is yet to be elucidated.

Abstract
Simvastatin, a potent inhibitor of 3-hydroxy-3-methylglutaryl coenzyme A reductase, was compared with cholestyramine resin in a randomized open-label 12-week multicenter study of 251 high-risk patients with familial or nonfamilial hypercholesterolemia. Simvastatin, 20 mg and 40 mg daily, produced mean reductions in total cholesterol of 26% and 33%, respectively, and reductions in low-density lipoprotein cholesterol level of 32% and 40%. Cholestyramine resin, 4 to 12 g twice daily, reduced total cholesterol and low-density lipoprotein cholesterol levels 15% and 21%, respectively. High-density lipoprotein cholesterol levels were increased 8% to 10% by all treatments. Plasma triglyceride levels were moderately decreased by simvastatin treatment, while triglyceride levels increased with cholestyramine treatment. Simvastatin was better tolerated than cholestyramine, which had numerous gastrointestinal tract side effects. No patient had a serious drug-related adverse event.

Abstract
A numerical diagnostic key for enteric organisms is described which permits the identification of typical strains and of biochemical variants with high accuracy. Unknown strains are inoculated into a basic set of five media which permit the testing of eight biochemical reactions. The positive reactions are assigned points, and the score of a strain is added up, after which the identification of the strain is obtained from a table. In many instances, the final identification is obtained with this set of biochemical tests; and, in other instances, a small number of additional tests are required to distinguish between organisms giving the same score in the basic set of biochemical tests. The key permits an accurate, rapid, and economical differentiation of the typical and the more common atypical biotypes of enteric organisms in the clinical laboratory.
