Surgical Opportunism for Hand Reconstruction Following a Mutilating Injury: A Case Report.

We report our management of a 53-year-old female who suffered a wood planer hand-mutilating injury with significant dorsal soft tissue loss and partial metacarpophalangeal joint (MCPJ) amputations of the thumb, index, and middle fingers. The middle finger was deconstructed for "spare parts" and a vascularized osteochondral graft was utilized to reconstruct the metacarpal articular surface of the index finger proximal phalanx, allowing the pedicled transposition of the index finger to the third metacarpal. The middle finger's distal interphalangeal joint was transplanted non-vascularly to recreate the thumb MCPJ and the elevation of a middle finger fillet flap allowed dorsal wound coverage. The patient did well initially but required ulnar collateral ligament reconstruction with a palmaris longus tendon graft following MCPJ instability 10 months postoperatively. Nonetheless, she progressively regained thumb opposition and pinch grip and continues to have successful aesthetic and functional outcomes six years postoperatively, supporting the efficacy of non-vascularized joint transfers when vascularized options are superfluous or unavailable.

Help-Seeking Behaviors in a Community Experiencing Multiple, Concurrent Natural Disasters. Lessons from a Greater Houston Community.

Previous disaster research exploring mental health consequences has been conducted after a single disaster. Community mental health nurses offer critical support in the aftermath of a disaster through complex assessments, psychosocial education and treatment. This research examines help-seeking behaviors in a Greater Houston community struggling with two simultaneous disasters, a historic winter freeze amidst the COVID-19 pandemic. Three Mental Health Crisis clinics, staffed by an interdisciplinary team, offered walk-in crisis services. The study characterizes adults who accessed services and describes those who accepted follow-up, subsidized behavioral health therapy or case management, including populations experiencing health disparities. Statistical analysis included descriptive and inferential statistics. Those who recognized the need for behavioral health care and accessed episodic care differed from those who accepted follow-up care. The population that was more likely to accept follow up care largely consisted of females, individuals without a previously existing mental health condition, those who reported trauma exposure, and young adults of Hispanic/Latino origin. Nurses can leverage female support to inspire male adults to seek care and advocate for increased resources and training to support culturally relevant care. Nurses and the interdisciplinary team need to assess for trauma exposure, as it influences care decisions.

Thg1 family 3'-5' RNA polymerases as tools for targeted RNA synthesis.

Members of the 3'-5' RNA polymerase family, comprised of tRNAHis guanylyltransferase (Thg1) and Thg1-like proteins (TLPs), catalyze templated synthesis of RNA in the reverse direction to all other known 5'-3' RNA and DNA polymerases. Discovery of enzymes capable of this reaction raised the possibility of exploiting 3'-5' polymerases for post-transcriptional incorporation of nucleotides to the 5'-end of nucleic acids without ligation, and instead by templated polymerase addition. To date, studies of these enzymes have focused on nucleotide addition to highly structured RNAs, such as tRNA and other non-coding RNA. Consequently, general principles of RNA substrate recognition and nucleotide preferences that might enable broader application of 3'-5' polymerases have not been elucidated. Here, we investigated the feasibility of using Thg1 or TLPs for multiple nucleotide incorporation to the 5'-end of a short duplex RNA substrate, using a templating RNA oligonucleotide provided in trans to guide 5'-end addition of specific sequences. Using optimized assay conditions, we demonstrated a remarkable capacity of certain TLPs to accommodate short RNA substrate-template duplexes of varying lengths with significantly high affinity, resulting in the ability to incorporate a desired nucleotide sequence of up to 8 bases to 5'-ends of the model RNA substrates in a template-dependent manner. This work has further advanced our goals to develop this atypical enzyme family as a versatile nucleic acid 5'-end labeling tool.

Not Only How Much But How: The Importance Of Diversifying Funding Streams In A Reimagined Public Health System.

Revenue diversification may be a synergistic strategy for transforming public health, yet few national or trend data are available. This study quantified and identified patterns in revenue diversification in public health before and during the COVID-19 pandemic. We used National Association of County and City Health Officials' National Profile of Local Health Departments study data for 2013, 2016, 2019, and 2022 to calculate a yearly diversification index for local health departments. Respondents' revenue portfolios changed fairly little between 2016 and 2022. Compared with less-diversified local health departments, well-diversified departments reported a balanced portfolio with local, state, federal, and clinical sources of revenue and higher per capita revenues. Less-diversified local health departments relied heavily on local sources and saw lower revenues. The COVID-19 period exacerbated these differences, with less-diversified departments seeing little revenue growth from 2019 to 2022. Revenue portfolios are an underexamined aspect of the public health system, and this study suggests that some organizations may be under financial strain by not having diverse revenue portfolios. Practitioners have ways of enhancing diversification, and policy attention is needed to incentivize and support revenue diversification to enhance the financial resilience and sustainability of local health departments.

Implant-Based Gluteal Augmentation: Comparing Complications Between Single- and Double-Incision Techniques.

BACKGROUND: Gluteal implants are gaining popularity as an alternative to fat grafting for gluteal augmentation. This study aims to compare complication rates between single- and double-incision techniques for implant placement in gluteal augmentation from a single surgeon's experience. METHODS: Retrospective analysis of a single surgeon's implant-based gluteal augmentations was conducted between October 2018 and August 2022. Consecutive patient cases were reviewed at the beginning and end of the designated period to compare both incision techniques after switching from the single- to double-incision technique in September 2020. Demographics and postoperative complications were compared. Statistical comparisons were made using the independent sample t-test for quantitative variables and the Fisher's exact test for categorical variables. RESULTS: The study included 134 single-incision patients (247 implants) and 47 double-incision patients (91 implants). Baseline demographic and clinical characteristics between the two groups were similar. Overall complication rate per implant was higher in the single-incision group (16.6% vs. 6.6%, p = 0.02). The most common complication per implant was delayed wound healing (single incision: 9.7%, double incision: 5.5%). The odds ratio of developing at least one complication in the double compared to the single-incision group was 0.44 (95% CI: 0.19, 0.92). CONCLUSIONS: The double incision technique demonstrates a lower complication rate than the single-incision technique for implant-based gluteal augmentation. The most common complication in both groups was delayed wound healing which responded in most patients to conservative wound care. These results support using the double-incision technique for implant-based gluteal augmentation. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

Pathophysiology of Preeclampsia-Induced Vascular Dysfunction and Implications for Subclinical Myocardial Damage and Heart Failure.

Tragically, preeclampsia is a leading cause of pregnancy-related complications and is linked to a heightened risk for morbid and fatal cardiovascular disease (CVD) outcomes. Although the mechanism connecting preeclampsia to CVD risk has yet to be fully elucidated, evidence suggests distinct pathways of early and late preeclampsia with shared CV risk factors but with profound differences in perinatal and postpartum risk to the mother and infant. In early preeclampsia, <34 weeks of gestation, systemic vascular dysfunction contributes to near-term subclinical myocardial damage. Hypertrophy and diastolic abnormalities persist postpartum and contribute to early onset heart failure (HF). This HF risk remains elevated decades later and contributes to premature death. Black women are at the highest risk of preeclampsia and HF. These findings support closer monitoring of women postpartum, especially for those with early and severe preeclampsia to control chronic hypertension and reduce the potentially preventable sequelae of heightened CVD and HF risk.

Integrated approach of white analytical chemistry and design of experiments to microwave-assisted sensitive and eco-friendly spectrofluorimetric estimation of mirabegron using 4-chloro-7-nitrobezofuran as biosensing fluorescent probe.

The USFDA recently approved mirabegron, a novel once-daily ß-3 adrenoceptor agonist for oral administration, as a transformative treatment for overactive bladder. Despite the existence of numerous analytical methods for the assay and bioanalysis of mirabegron, it's perplexing that none have explored the domain of microwave-assisted sensitive spectrofluorimetric method for mirabegron estimation, even after extensive literature review. Adding to the enigma is the insistence of current analytical methods on using expensive and harmful organic solvents, posing a threat to marine life and the broader environment. Recently, the white analytical chemistry approach has been introduced to develop analytical methods that are cost-effective, environmentally friendly, and user-friendly. Consequently, a white analytical chemistry-based, sensitive, and eco-friendly spectrofluorimetric estimation of mirabegron has been initiated, using 4-Chloro-7-nitrobenzofurazan as a fluorescent biosensing probe. The development of this robust method involved a series of experiments designed to minimize solvent and time wastage. Through a combination of fractional factorial and Box-Behnken designs, researchers identified the critical variables and optimized the method to perfection. This method was validated according to the stringent ICH Q2 (R2) and USFDA guidelines, ensuring its reliability and accuracy. Once approved, this sensitive spectrofluorimetric method was tested, accurately estimating mirabegron levels in commercial formulations and rat plasma samples. To further enrich the study, a comprehensive evaluation of existing analytical methods was conducted alongside the proposed spectrofluorimetric method, using advanced tools like the AGREE calculator, GAPI software, and RGB model to assess their eco-friendliness and effectiveness in mirabegron estimation.

Molecular Basis of Cerebral Vasospasm: What Can We Learn from Transcriptome and Temporal Gene Expression Profiling in Intracranial Aneurysm?

Cerebral vasospasm (CV) is a significant complication following aneurysmal subarachnoid hemorrhage (aSAH), and lacks a comprehensive molecular understanding. Given the temporal trajectory of intracranial aneurysm (IA) formation, its rupture, and development of CV, altered gene expression might be a molecular substrate that runs through these clinical events, influencing both disease inception and progression. Utilizing RNA-Seq, we analyzed tissue samples from ruptured IAs with and without vasospasm to identify the dysregulated genes. In addition, temporal gene expression analysis was conducted. We identified seven dysregulated genes in patients with ruptured IA with vasospasm when compared with those without vasospasm. We found 192 common genes when the samples of each clinical subset of patients with IA, that is, unruptured aneurysm, ruptured aneurysm without vasospasm, and ruptured aneurysm with vasospasm, were compared with control samples. Among these common genes, TNFSF13B, PLAUR, OSM, and LAMB3 displayed temporal expression (progressive increase) with the pathological progression of disease that is formation of aneurysm, its rupture, and consequently the development of vasospasm. We validated the temporal gene expression pattern of OSM at both the transcript and protein levels and OSM emerges as a crucial gene implicated in the pathological progression of disease. In addition, RSAD2 and ATP1A2 appear to be pivotal genes for CV development. To the best of our knowledge, this is the first study to compare the transcriptome of aneurysmal tissue samples of aSAH patients with and without CV. The findings collectively provide new insights on the molecular basis of IA and CV and new leads for translational research.

Surgical outcomes and revision rates for velopharyngeal insufficiency (VPI) in syndromic and non-syndromic children: A systematic review and meta-analysis.

PURPOSE: To evaluate pre- and post-operative resonance, surgical technique, revision rate, and revision indication among syndromic and non-syndromic children with velopharyngeal insufficiency (VPI). MATERIALS AND METHODS: A systematic review was conducted through July 2022. Children surgically treated for VPI were included. A meta-analysis of single means, proportions, comparison of proportions, and mean differences with 95 % confidence interval [CI] was conducted. RESULTS: Twenty-three articles (n = 1437) were included in the analysis. The most common surgery was Sphincter Pharyngoplasty (SP), 62.6 % [31.3-88.9] for syndromic and 76.3 % [37.5-98.9] for non-syndromic children. Among all surgical techniques, for syndromic and non-syndromic children, 54.8 % [30.9-77.5] and 73.9 % [61.3-84.6] obtained normal resonance post-operatively, respectively. Syndromic patients obtained normal resonance post-operatively in 83.3 % [57.7-96.6] of Combined Furlow Palatoplasty and Sphincter Pharyngoplasty (CPSP), 72.6 % [54.5-87.5] of Pharyngeal Flap (PF), and 45.1 % [13.2-79.8] of Sphincter Pharyngoplasty (SP) surgeries. Non-syndromic patients obtained normal resonance post-operatively in 79.2 % [66.4-88.8] of PF and 75.2 % [61.8-86.5] of SP surgeries. The revision rate for syndromic and non-syndromic patients was 19.9 % [15.0-25.6] and 11.3 % [5.8-18.3], respectively. The difference was statistically significant, 8.6 % [2.9-15.0, p = 0.003]. Syndromic patients who underwent PF were least likely to undergo revision surgery as compared to SP and CPSP, 7.7 % [2.3-17.9] vs. 23.7 % [15.5-33.1] and 15.3 % [2.8-40.7], respectively. CONCLUSIONS: Syndromic children had higher revision rates and were significantly less likely to obtain normal resonance following primary surgery than non-syndromic patients. Among syndromic children, PF and CPSP have been shown to improve resonance and reduce revision rates more so than SP alone.

The utility of PET imaging in depression.

This educational review article aims to discuss growing evidence from PET studies in the diagnosis and treatment of depression. PET has been used in depression to explore the neurotransmitters involved, the alterations in neuroreceptors, non-neuroreceptor targets (e.g., microglia and astrocytes), the severity and duration of the disease, the pharmacodynamics of various antidepressants, and neurobiological mechanisms of non-pharmacological therapies like psychotherapy, electroconvulsive therapy, and deep brain stimulation therapy, by showing changes in brain metabolism and receptor and non-receptor targets. Studies have revealed alterations in neurotransmitter systems such as serotonin, dopamine, GABA, and glutamate, which are linked to the pathophysiology of depression. Overall, PET imaging has furthered the neurobiological understanding of depression. Despite these advancements, PET findings have not yet led to significant changes in evidence-based practices. Addressing the reasons behind inconsistencies in PET imaging results, conducting large sample size studies with a more standardized methodological approach, and investigating further the genetic and neurobiological aspects of depression may better leverage PET imaging in future studies.

Suture fixation of traumatic rib fracture flail segment with Klebsiella osteomyelitis.

We report the case of a 71-year-old male who initially presented with urosepsis and was found to have a rib fracture of his right 6th rib with a flail segment and an associated abscess. Given the concern for infection, surgical rib fixation with titanium plating was not pursued during the washout of his abscess and instead, he successfully underwent rib fracture stabilization with bilateral suture transfixation. He was continued on a prolonged course of antibiotics for Klebsiella pneumonia osteomyelitis and was discharged uneventfully with optimal pain control and adequate respiratory effort.

Structural Support for Large to Total Nasal Reconstruction.

When large defects of the nose are present, it is imperative to address all 3 layers: the external skin envelope, the osteocartilaginous support, and the inner mucosal lining. The middle structural framework is the primary factor in determining the overall shape of the nose, in addition to facilitating a functional and patent airway. As such, its reconstruction must be robust enough to provide lasting osteocartilaginous support while minimizing disfiguring bulk. The goal is replacement of missing tissue with grafts of similar strength, size, and shape. This article will review approaches to the reconstruction of structural support in large nasal defects.

Influenza A (H1N1) Virus Outbreak in the Districts of Chhattisgarh: A Cross-Sectional Study.

Background The H1N1 flu is a subtype of the influenza A virus, also known as the swine flu. An entirely new strain of the H1N1 virus started sickening people in the 2009-2010 flu season. It was a novel influenza virus combination that can infect humans, pigs, and birds. It was frequently referred to as the "swine flu." The virus may be able to spread for a little while longer in children and individuals with compromised immune systems. Objective The objective is to investigate the outbreaks of H1N1 among young adults in the Bastar District of Chhattisgarh. Methods Collection of the blood samples of 342 individuals between December 2015 and November 2017 was done. Thirty-one cases of Influenza A (H1N1) PDM09 virus infection were identified and confirmed. The molecular relationship between viruses is identified by the real-time polymerase chain reaction (RT-PCR) method. Result The majority of samples (n=13) were sourced from Raipur Medical College, followed by contributions from Durg District Hospital (n=5), Raigarh Medical College (n=4), Rajnandgaon District Hospital (n=3), Jagdalpur Medical College (n=2), Bilaspur Medical College (n=2), and smaller contributions from Dhamtari District Hospital and Gariyabandh Primary Health Care. Among these, 31 samples tested positive for Influenza A (H1N1) PDM 2009 virus, with a slightly higher prevalence among 19 female patients. Age-wise distribution revealed higher proportions of positive cases in the age groups of 0-10 years, 31-40 years, and 21-30 years. In the molecular analysis, 154 samples showed no target amplification, while 125 samples exhibited amplification of only Influenza A without subtype (H1) amplification. Remarkably, 31 patients who tested positive for Influenza A (H1N1) died from the virus; most of the deaths were in children under five and middle-aged adults. Conclusion The detection of Influenza A (H1N1) PDM 2009 virus, especially among females, indicates its persistent circulation. Positive cases were prevalent among younger and middle-aged individuals. Molecular analysis showed subtype variations, with significant fatalities observed in children under five and middle-aged adults, emphasizing the severity of the virus across different age groups. It is advised that in order to keep Indian influenza surveillance up to date and robust, more epidemiological data should be gathered, along with information on risk factors like immunization status, hospitalization, and mortality rates should be estimated, and influenza case subtyping should be improved.

Androgen receptor splice variants drive castration-resistant prostate cancer metastasis by activating distinct transcriptional programs.

One critical mechanism through which prostate cancer (PCa) adapts to treatments targeting androgen receptor (AR) signaling is the emergence of ligand-binding domain-truncated and constitutively active AR splice variants, particularly AR-V7. While AR-V7 has been intensively studied, its ability to activate distinct biological functions compared with the full-length AR (AR-FL), and its role in regulating the metastatic progression of castration-resistant PCa (CRPC), remain unclear. Our study found that, under castrated conditions, AR-V7 strongly induced osteoblastic bone lesions, a response not observed with AR-FL overexpression. Through combined ChIP-seq, ATAC-seq, and RNA-seq analyses, we demonstrated that AR-V7 uniquely accesses the androgen-responsive elements in compact chromatin regions, activating a distinct transcription program. This program was highly enriched for genes involved in epithelial-mesenchymal transition and metastasis. Notably, we discovered that SOX9, a critical metastasis driver gene, was a direct target and downstream effector of AR-V7. Its protein expression was dramatically upregulated in AR-V7-induced bone lesions. Moreover, we found that Ser81 phosphorylation enhanced AR-V7's pro-metastasis function by selectively altering its specific transcription program. Blocking this phosphorylation with CDK9 inhibitors impaired the AR-V7-mediated metastasis program. Overall, our study has provided molecular insights into the role of AR splice variants in driving the metastatic progression of CRPC.

Attempted repair of chest wall injury following penetrating injury with surgical stabilization rib and autologous bone graft: A case report.

Rib fractures are one of the most common injuries following blunt trauma. When associated with penetrating trauma, the projectile velocity and immense energy transfer cause significant rib fracture displacement and fragmentation. As a result, these patients are potentially exposed to an even higher risk of complications compared to those seen in more simple rib fractures. Unfortunately, there is limited research regarding technical considerations for surgical stabilization of rib fractures (SSRF) in severely displaced rib fractures with bone loss following penetrating injury. We present the case of a 21-year-old male gunshot wound victim with severely displaced and comminuted rib fractures in which we utilized an autologous bone graft bridge during SSRF to enhance fracture unionization, chest wall stability, and cosmesis. Unfortunately, the bone graft failed to incorporate into surrounding tissue.

Multidisciplinary approach to the management of renal angiomyolipoma with inferior vena cava thrombus and pulmonary embolism: a case report.

Renal angiomyolipoma (AML) is a benign tumor with rare venous extension. We present a case of a patient with renal AML with inferior vena cava (IVC) tumor thrombus and acute pulmonary embolism (PE). A 34-year-old female presented with chest pain. Imaging revealed a 5 cm right renal AML, with tumor thrombus into the renal vein and IVC, and acute left lower lobe PE. Right radical nephrectomy and caval thrombectomy were performed using intraoperative ultrasound. Rarely, these benign tumors generate thrombus with caval extension. The location of IVC thrombus guides surgical planning, which may involve suprahepatic IVC control or cardiopulmonary bypass. Early involvement of a multidisciplinary team with extensive preoperative planning can help achieve successful outcomes.

Speech Intelligibility in Patients with Facial Paralysis.

Background: Patients with facial paralysis often report frustration with communication; however, there are limited data regarding intelligibility deficiencies. Objective: To compare speech intelligibility in patients with severe and non-severe facial paralysis, and in patients with or without synkinesis. Methods: Video and audio data were reviewed retrospectively. Groups were stratified as follows: Group A - severe paralysis (Sunnybrook 0-20) without synkinesis; Group B - non-severe (Sunnybrook >20) paralysis without synkinesis; and Group C - non-severe paralysis with synkinesis. Intelligibility was assessed by lay-people and a speech and language pathologist (SLP) using the Frenchay Dysarthria Assessment Version 2 (FDA-2). A receiver operating characteristic (ROC) curve was used to determine a Sunnybrook cutoff for intelligibility. Results: Eighty cases were reviewed with mean age 55.6, 53.8% female. 25.0% were in Group A, 30.0% Group B, and 45.0% in Group C. Lay-people rated 15.0% and the SLP rated 28.7% as having intelligibility deficiency. An ROC curve demonstrated that patients with Sunnybrook ≤18.5 were more likely to have intelligibility abnormality. Conclusion: Patients with Sunnybrook ≤18.5 are more likely to demonstrate intelligibility deficiency. Clinicians with a more trained ear are more likely to identify intelligibility abnormality compared with lay-people. Those with synkinesis are more intelligible compared with those without it.
