RESUMEN
BACKGROUND: Diabetes mellitus is a global disease identified by hyperglycemia due to defects in insulin secretion, insulin action, or both. OBJECTIVE: The main objective of this research was to evaluate the ability of gelatinized Poly(ethylene glycol) (PEG) microparticles to be used as carriers for oral insulin delivery via double emulsion preparation. METHODS: Five different batches of the formulation consisting of gelatin:PEG were prepared as follows: 0:1 (W1), 1:0 (W2), 1:1 (W3), 1:3 (W4), and 3:1 (W5). The prepared microparticles (from insulin-loaded batches) had particle sizes ranging from 19.5 ± 0.32-23.9 ± 0.22 µm and encapsulation and loading capacities ranging from 78.8 ± 0.24-88.9 ± 0.95 and 22.2 ± 0.96-29.7 ± 0.86%, respectively. The minimum and maximum in vitro release rates were 8.0 and 66.0%, respectively, for batches W1 and W2 at 8 h. RESULTS: Insulin-loaded MPs induced a significant decrease in glucose levels, with a reduction from 100 to 33.35% in batch W5 at 9 h compared to that of subcutaneous insulin (100 to 22.63%). A liver function study showed that the formulation caused no obvious toxicity to the experimental rats. CONCLUSION: Gelatinized PEG-based microparticles as insulin delivery systems may open a new window into the development of oral insulin for diabetic treatment.
RESUMEN
BACKGROUND: Traditional constraints specify that 700 cc of liver should be spared a hepatotoxic dose when delivering liver-directed radiotherapy to reduce the risk of inducing liver failure. We investigated the role of single-photon emission computed tomography (SPECT) to identify and preferentially avoid functional liver during liver-directed radiation treatment planning in patients with preserved liver function but limited functional liver volume after receiving prior hepatotoxic chemotherapy or surgical resection. METHODS: This phase I trial with a 3 + 3 design evaluated the safety of liver-directed radiotherapy using escalating functional liver radiation dose constraints in patients with liver metastases. Dose-limiting toxicities were assessed 6-8 weeks and 6 months after completing radiotherapy. RESULTS: All 12 patients had colorectal liver metastases and received prior hepatotoxic chemotherapy; 8 patients underwent prior liver resection. Median computed tomography anatomical nontumor liver volume was 1584 cc (range = 764-2699 cc). Median SPECT functional liver volume was 1117 cc (range = 570-1928 cc). Median nontarget computed tomography and SPECT liver volumes below the volumetric dose constraint were 997 cc (range = 544-1576 cc) and 684 cc (range = 429-1244 cc), respectively. The prescription dose was 67.5-75 Gy in 15 fractions or 75-100 Gy in 25 fractions. No dose-limiting toxicities were observed during follow-up. One-year in-field control was 57%. One-year overall survival was 73%. CONCLUSION: Liver-directed radiotherapy can be safely delivered to high doses when incorporating functional SPECT into the radiation treatment planning process, which may enable sparing of lower volumes of liver than traditionally accepted in patients with preserved liver function. TRIAL REGISTRATION: NCT02626312.

Introduction: Racial/ethnic disparities in maternal mortality rates represent one of the most significant areas of disparities amongst all conventional population perinatal health measures in the U.S. The alarming trends and persistent disparities of outcomes by race/ethnicity and geographic location reinforce the need to focus on ensuring quality and safety of maternity care for all women. Despite complex multilevel factors impacting maternal mortality and morbidity, there are evidence-based interventions that, when facilitated consistently and properly, are known to improve the health of mothers before, during and after pregnancy. The objective of this project is to test implementation of pre-conception counseling with father involvement in community-based settings to improve cardiovascular health outcomes before and during pregnancy in southeastern United States. Methods and Analysis: This study has two components: a comprehensive needs and assets assessment and a small-scale pilot study. We will conduct a community informed needs and assets assessment with our diverse stakeholders to identify opportunities and barriers to preconception counseling as well as develop a stakeholder-informed implementation plan. Next, we will use the implementation plan to pilot preconception counseling with father involvement in community-based settings. Finally, we will critically assess the context, identify potential barriers and facilitators, and iteratively adapt the way preconception counseling can be implemented in diverse settings. Results of this research will support future research focused on identifying barriers and opportunities for scalable and sustainable public health approaches to implementing evidence-based strategies that reduce maternal morbidity and mortality in the southeastern United States' vulnerable communities. Discussion: Findings will demonstrate that preconception counseling can be implemented in community health settings in the southeastern United States. Furthermore, this study will build the capacity of community-based organizations in addressing the preconception health of their clients. We plan for this pilot to inform a larger scaled-up clinical trial across community health settings in multiple southeastern states.
RESUMEN
Background: The Nigerian mental health law titled the Lunacy Act of 1958 has been under scrutiny for violating the human rights of people with mental illness. The call to reform the obsolete Lunacy Act has garnered attention from the government, as the law has been unamended for over 60 years. Aim: This study presents the challenges and implications of the new mental health law to the mental health services of Nigeria. Methods: ScienceDirect, PubMed, and Google Scholar were used to find pertinent material. The implications and difficulties facing the new mental health law examined from the literature were discussed. Recommendations were made following an exploratory search for literature on mental health legislation in Nigeria. Results: The new Law in Section 5(6) saw the introduction of mental health services in primary and secondary healthcare. It also addresses critical issues such as non-discrimination, fundamental human rights, standards of treatment, access to information, confidentiality and autonomy, and the employment rights of persons with mental health and substance abuse-related disorders. The Law failed to include mental health services in the country's health insurance system. Conclusion: There is a need for legislation to meet people's mental health needs and encourage them to seek treatments, such as regulations that protect against discrimination and harsh treatment of people with mental illness. Contribution: Nigerian mental health services would benefit from the new mental health law if the key issues raised in this review are addressed.
RESUMEN
Written exposure therapy (WET) is a brief, manualized trauma-focused treatment typically delivered in five individual weekly sessions. Given the brevity and effectiveness of WET, researchers have begun to focus on its delivery in a massed format. However, only one case study examining massed delivery has been published to date. As such, the objective of the current study was to examine the acceptability, feasibility, and preliminary effectiveness of massed WET among veterans with a trauma- and stressor-related disorder receiving care on an acute inpatient mental health unit. Veterans (N = 26) were assessed prior to, immediately after, and 1 month following massed WET. Most veterans found massed WET to be useful and acceptable. Recruitment and retention rates suggested that the treatment was feasible. Notably, the results revealed statistically significant reductions in overall posttraumatic stress symptoms, ηp 2 = .81, p < .001; depressive symptoms, ηp 2 = .71, p < .001; and functional impairment, ηp 2 = .42, p = .002. These findings add to a growing body of literature highlighting the preliminary effectiveness of WET across various settings, populations, and delivery formats. Limitations include the small sample size and uncontrolled design.

RESUMEN
The PTSD Checklist for DSM-5 (PCL-5) and the Clinician-Administered PTSD Scale for DSM-5 (CAPS-5) are two of the most widely used and well-validated PTSD measures providing total and subscale scores that correspond with DSM-5 PTSD symptoms. However, there is little information about the utility of subscale scores above and beyond the total score for either measure. The current study compared the proposed DSM-5 four-factor model to a bifactor model across both measures using a sample of veterans (N = 1,240) presenting to a Veterans Affairs (VA) PTSD specialty clinic. The correlated factors and bifactor models for both measures evidenced marginal-to-acceptable fit and were retained for further evaluation. Bifactor specific indices suggested that both measures exhibited a strong general factor but weak lower-order factors. Structural regressions revealed that most of the lower-order factors provided little utility in predicting relevant outcomes. Although additional research is needed to make definitive statements about the utility of PCL-5 and CAPS-5 subscales, study findings point to numerous weaknesses. As such, caution should be exercised when using or interpreting subscale scores in future research.
RESUMEN
INTRODUCTION: The mortality rate in patients on maintenance hemodialysis (HD) is high and is associated with low functional capacity (FC). We analyzed the association of FC and COVID-19 lethality among HD patients. METHODS: A cohort study that included evaluations of FC in patients on HD was underway, and the association between FC and lethality was included as an ad-hoc outcome. RESULTS: One hundred and twelve patients were submitted to a physical, 31 patients contracted symptomatic COVID-19, 20 recovered and 11 died (lethality rate of 35.5%). There was a difference between survivors and non-survivors on six-minutes-walking-test (6MWT) 386.1 ± 112.8 versus 296.9 ± 103.3 meters (p = 0.04), 30 s sit-to-stand test (30CST) score 11.7 ± 3.1 versus 7.7 ± 4.1 (p = 0.006), and timed up and go test (TUG) 9.4 versus 13.6 s (p = 0.009). There was also an association between percentages of predicted 6MWT, 30CST, and TUG with COVID-19 lethality. CONCLUSION: Patients on maintenance HD with poorer physical performance presented the worst prognosis from COVID-19 pandemic.

BACKGROUND AND PURPOSE: Parathyroid carcinoma is the rarest endocrine neoplasm with very few published data discussing its imaging appearance with primary focus on ultrasound imaging features. We present our 23 years institutional experience to highlight multimodality imaging evaluation at presentation and at recurrence. MATERIAL AND METHODS: Retrospective chart review of clinical and pathological diagnosis of parathyroid carcinoma patients presented for initial or recurrent disease management at M.D. Anderson Cancer Center between the period of January 2000 and February 2023 was performed. Imaging findings on US, CT, PET/CT, and technetium-99m sestamibi were analyzed for initial and local recurrent parathyroid carcinoma. We further assess patterns of distant recurrence and its location. RESULTS: Twenty three patients with pathological and clinical diagnosis of initial (14 patients) or recurrent parathyroid carcinoma (14 patients) were included in this study. US findings of parathyroid carcinoma were larger lesions, increased/irregular vascularity, and non-circumscribed margins. Multiphasic CT findings of parathyroid carcinoma included an arterially enhancing lesion that is hypoenhancing relative to the thyroid and demonstrates no washout on delayed imaging. Highly suggestive findings for recurrent disease included a hypoechoic solid nodule (91.67%) with increased vascularity on ultrasound (81.8%) with corresponding enhancement on CT. CONCLUSION: Parathyroid carcinoma is a rare malignancy often diagnosed after surgical resection. We provided CT and US imaging features that are helpful in suggesting the diagnosis of parathyroid carcinoma and detection of early local recurrence.

OBJECTIVE: Despite widespread use of the posttraumatic stress disorder (PTSD) Checklist for Diagnostic and Statistical Manual of Mental Disorders-fifth edition (PCL-5) across various trauma-exposed populations, little is known about the psychometric properties of the instrument in certain ethnic minority groups with increased risk of trauma exposure, including Black veterans. To this end, the current study examined the internal consistency of the PCL-5, convergent validity using correlations between the PCL-5 and another measure of PTSD, and discriminant validity using correlations between the PCL-5 and other commonly occurring psychiatric symptoms, including depression as well as alcohol and substance misuse. METHOD: The sample was composed of 327 Black veterans (84% male, Mage = 51.87, SD = 13.72) presenting to a PTSD specialty clinic at a large Veterans Affairs hospital in the Midwest United States to receive psychological services. In addition to a diagnostic interview, veterans were asked to complete a brief battery of self-report questionnaires to assist with diagnostic clarification and treatment planning. RESULTS: The PCL-5 demonstrated excellent internal consistency. Furthermore, the PCL-5 was significantly and positively correlated with PTSD diagnostic status, suggesting evidence of convergent validity. Finally, the PCL-5 was strongly correlated with symptoms of depression and moderately correlated with alcohol and substance misuse. CONCLUSIONS: Findings suggest that the PCL-5 is a psychometrically sound measure to assess PTSD symptoms among Black veterans. Considering the brevity of PCL-5 administration, clinicians should consider utilizing this and other psychometric tests in clinical care to reduce disparities in health equity among Black patients.

INTRODUCTION AND HYPOTHESIS: We evaluated family medicine obstetric providers' identification and categorization of vaginal delivery lacerations in the USA. We hypothesized that there would be inaccuracy in family medicine physicians' identification of vaginal delivery injuries, similar to our previous studies of midwives and obstetricians (OBs). METHODS: We included clinically active physicians who attended deliveries within 2 years and evaluated their identification and categorization of delivery lacerations using descriptive text and visual images. We asked about their education on this topic and how they document lacerations in the labor and delivery record. RESULTS: We analyzed 250 completed responses (70% of opened surveys). Fifty-five percent of respondents characterized their obstetric laceration training as "good" or "excellent" and half previously had education on obstetric lacerations. The median accuracy overall for the classification and identification of perineal lacerations was 78% (IQR 56-91%). Respondents frequently mischaracterized nonperineal lacerations. Few respondents (36%) reported using the third-degree injury subclassification system. In adjusted analysis, the highest scoring respondents were board certified in family medicine, with fewer years in practice, and a higher obstetric volume. CONCLUSIONS: Obstetric laceration diagnoses may be inaccurate, which could influence perinatal quality and patient outcomes. We found gaps in knowledge similar to previous reports on midwives and obstetricians in the USA. These data suggest a need for increased education and training on obstetric injuries, perhaps especially for physicians with less obstetric activity. Improved categorization and identification of vaginal delivery trauma can impact management and improve women's postpartum care and long-term pelvic floor outcomes.

BACKGROUND: Robotic donor nephrectomy (RDN) has emerged as a safe alternate to laparoscopic donor nephrectomy (LDN), offering improved visualization, instrument dexterity and ergonomics. There is still concern about how to safely transition from LDN to RDN. METHODS: We performed a retrospective review of 150 consecutive living donor operations (75 LDN and 75 RDN) at our center, comparing the first 75 RDN's with the last 75 LDN's performed prior to the initiation of the robotic transplant program. Operative times and complications were used as surrogates of efficiency and safety, respectively, to estimate the learning curve with RDN. RESULTS: RDN was associated with a longer total operative time (RDN 182 vs LDN 144 min; P < 0.0001) but a significantly shorter post-operative length of stay (RDN 1.8 vs LDN 2.1 days; P = 0.0213). Donor complications and recipient outcomes were the same between both groups. Learning curve of RDN was estimated to be about 30 cases. CONCLUSIONS: RDN is a safe alternate to LDN with acceptable donor morbidity and no negative impact on recipient outcomes even during the early part of the RDN learning curve. Surgeon preferences for the robotic approach compared to traditional laparoscopy will require further scrutiny to improve ergonomics and operative efficiency.

This research investigates the potentials of prodigiosin(PG) derived from bacteria and its formulations against triple-negative breast (TNB), lung, and colon cancer cells. The PG was extracted from S. marcescens using continuous batch culture, characterized, and formulated into lyophilized parenteral nanoparticles (PNPs). The formulations were characterized with respect to entrapment efficiency (EE), DSC, FT-IR, TEM, and proton nuclear magnetic resonance (1H NMR) spectroscopy. In vitro drug release was evaluated in phosphate buffer (pH 7.4) while acute toxicity, hematological and histopathological studies were performed on rats. The in vitro cytotoxicity was evaluated against TNB (MCF-7), lung (A-549), and colon (HT-29) cancer cell lines. High EE (92.3 ± 12%) and drug release of up to 89.4% within 8 h were obtained. DSC thermograms of PG and PG-PNPs showed endothermic peaks indicating amorphous nature. The FT-IR spectrum of PG-PNPs revealed remarkable peaks of pure PG, indicating no strong chemical interaction between the drug and excipients. The TEM micrograph of the PG-PNPs showed nano-sized formulations (20-30 nm) whose particles were mostly lamellar and hexagonal structures. The 1H NMR result revealed the chemical structure of PG showing all assigned proton chemical shifts. Toxicity results of the PG and its formulation up to a concentration of 5000 mg/kg showed insignificant vacuolar changes of hepatocytes in the liver, with normal renal medulla and cortex in the kidney. The PG and PG-PNPs inhibited the growth of breast, lung, and colon cell lines. The nano-sized lipid formulation (PG-PNPs) showed potential in PG delivery and cancer treatments.

BACKGROUND: Evidence comparing different exercise modalities in individuals undergoing hemodialysis remains incipient. Our aim was to conduct a systematic review and network meta-analysis of randomized clinical trials to compare and synthesize the efficacy of five different intradialytic exercise modalities and home-based training in this population. DESIGN, SETTING, PARTICIPANTS, AND MEASUREMENTS: Studies were searched in PubMed/MEDLINE, Cochrane Library, Embase, Cinahl, and Scopus from their inception to 19 September 2022. We used traditional random-effects models and Bayesian network meta-analysis models. The risk of bias was assessed using the RoB v.2.0 tool, and the assessment of confidence in the results through the Confidence in Network Meta-Analysis (CINeMA) tool. RESULTS: Seventy-eight studies involving 3326 participants were included. Our network meta-analysis showed that combined training was the intervention with the best performance to increase VO2 peak [mean difference (MD) = 3.94 ml/kg/min; 95% credible interval (CrI), 2.38 to 5.76] and to reduce diastolic blood pressure (MD = -5.19 mmHg; 95%CrI, -9.35 to -0.96) compared to the usual care group. Inspiratory muscle training was the intervention that most improved the 6-minute walk test distance (MD = 70.97 m; 95%CrI, 18.09 to 129.87). C-reactive protein decreased in resistance training (MD = -2.6 mg/l; 95%CrI, -4.97 to -0.33) and aerobic training (MD = -1.4 mg/l; 95%CrI, -3.15 to -0.06). Kt/V improved in aerobic training (MD = 0.11; 95%CrI, 0.02 to 0.18), and SF-36 physical functioning outcomes improved in resistance training (MD = 10.66 points; 95%Crl, 1.91 to 20.22). No intradialytic exercise modality was superior to others or comparable with home-based training in improving the evaluated outcomes. Subgroup analysis revealed that exercise interventions >12 weeks improved functional capacity more than interventions ≤12 weeks, and that combined training reduces diastolic blood pressure only after 12 weeks of follow-up. Furthermore, our results suggest that moderate or moderate-to-vigorous intensity training leads to more pronounced improvements in functional capacity, whereas mild or mild-to-moderate intensity training does not have the same effect. In this review, most of the included studies were assessed as having some concern, which resulted in a low to very low level of confidence in the overall findings. CONCLUSIONS: Both intradialytic training and home-based training can promote benefits for individuals undergoing hemodialysis, with no evidence of the superiority of either training modality over the other.

The rise of self-supervised learning (SSL) methods in recent years presents an opportunity to leverage unlabeled and domain-specific datasets generated by image-based plant phenotyping platforms to accelerate plant breeding programs. Despite the surge of research on SSL, there has been a scarcity of research exploring the applications of SSL to image-based plant phenotyping tasks, particularly detection and counting tasks. We address this gap by benchmarking the performance of 2 SSL methods-momentum contrast (MoCo) v2 and dense contrastive learning (DenseCL)-against the conventional supervised learning method when transferring learned representations to 4 downstream (target) image-based plant phenotyping tasks: wheat head detection, plant instance detection, wheat spikelet counting, and leaf counting. We studied the effects of the domain of the pretraining (source) dataset on the downstream performance and the influence of redundancy in the pretraining dataset on the quality of learned representations. We also analyzed the similarity of the internal representations learned via the different pretraining methods. We find that supervised pretraining generally outperforms self-supervised pretraining and show that MoCo v2 and DenseCL learn different high-level representations compared to the supervised method. We also find that using a diverse source dataset in the same domain as or a similar domain to the target dataset maximizes performance in the downstream task. Finally, our results show that SSL methods may be more sensitive to redundancy in the pretraining dataset than the supervised pretraining method. We hope that this benchmark/evaluation study will guide practitioners in developing better SSL methods for image-based plant phenotyping.
RESUMEN
BACKGROUND: Organ waste is a major cause of the donor liver shortage. Roughly 67% of recovered organ donors have liver utilization annually. A new technology called normothermic machine perfusion (NMP) offers a way to recover marginal and declined livers for transplant. We report interim results of the RESTORE trial (FDA investigational drug exemption trial NCT04483102) that aims to transplant NMP-treated livers that would otherwise be discarded. STUDY DESIGN: Declined livers were screened for NMP eligibility (eg donation after circulatory death [DCD] grafts with warm ischemic time <40 minutes, donation after brain death [DBD] grafts with cold ischemic time <8 hours). Livers meeting pre-NMP eligibility criteria received NMP using the OrganOx metra device for a minimum of 4 hours. All NMP-treated livers meeting the viability criteria were transplanted to consented recipients. RESULTS: Over 22 months, 60 declined livers from three organ procurement organizations (OPOs; 40 DCD and 20 DBD donor livers) were offered, and 22 livers (10 DCD and 12 DBD livers) met the pre-NMP eligibility. After NMP, 16 of 22 livers passed viability testing and were transplanted into needy recipients (median Model for End-Stage Liver Disease [MELD] score of 8, range 6 to 24), resulting in a 72.7% rescue rate (50% DCD, 91.7% DBD). The rate of early allograft dysfunction was 31.3%, but there were no graft-related deaths, primary nonfunction, or instances of nonanastomotic biliary strictures. CONCLUSIONS: Interim results of the RESTORE trial suggest that a sizable number of declined livers can be reclaimed. They are safe for transplantation and can enable lower MELD patients at high risk of morbidity and mortality to receive lifesaving grafts while offering OPOs a way to allocate more livers and reduce organ waste.

A 4-year 9-month-old beagle was presented for a 2-week history of acute onset of lowered tail carriage and faecal incontinence. Neurological examination was unremarkable except for an absent perineal reflex, there was no history of trauma. Blood work was unremarkable. Lumbosacral and coccygeal CT pre- and post-intravenous contrast revealed a large sacrococcygeal disc extrusion with mineralised material extending from the level of S2 and to midbody of Cd1. A dorsal laminectomy was performed from the cranial margin of S2 to the caudal margin of Cd1. A large volume of mineralised disc material was removed. The material was confirmed on histopathology to be consistent with extruded nucleus pulposus. The patient regained faecal continence within 3 days of hospital discharge. Based on a literature search this is the first report of a sacrococcygeal disc extrusion resulting in faecal incontinence, with successful surgical management.

OBJECTIVE: Despite a robust association between military sexual trauma (MST) and posttraumatic stress disorder (PTSD), few studies have examined factors that are associated with increased symptom severity. To this end, the current study was designed to examine the unique and interactive effects of gender and race on PTSD symptoms using a sample of MST survivors. METHOD: The sample included 126 veterans (71% Women, 29% Men; 70% Black/African American and 30% White/Caucasian) presenting for psychological services to a MST specialty clinic at a large Southeastern Veterans Affairs (VA) hospital. As part of their intake evaluation, veterans completed a diagnostic interview and battery of self-report questionnaires. RESULTS: Results revealed a main effect of gender and race such that veteran men and Black/African American veterans were found to have increased PTSD symptom severity. However, there was not a significant gender by race interaction. CONCLUSION: Findings are discussed with regard to previous research and treatment implications.

OBJECTIVE: Chronic pain and posttraumatic stress disorder (PTSD) are two highly prevaxlent and comorbid conditions common within veteran populations. Notably, those with comorbid pain and PTSD tend to have more severe presentations and poorer quality of life than those with either disorder alone. Despite this well-established relationship, limited research has examined the association between pain and PTSD symptom severity among women veterans with a history of military sexual trauma (MST). METHOD: The current study included 107 women veterans presenting for psychological services to an MST specialty clinic at a large southeastern Veterans Affairs (VA) hospital in the United States. RESULTS: Findings indicated a significant relationship between pain and overall PTSD symptom severity, as well as the intrusions and arousal and reactivity symptom clusters. Contrary to prediction, there was not a significant relationship between pain interference and PTSD symptom or cluster severity. CONCLUSION: Results highlight the importance of inquiring about pain when working with women veterans with a history of MST. Future research aimed at disentangling the casual relationship between pain and PTSD symptoms is crucial to enhance our understanding of these constructs.
