Patterns and Factors Associated With Alcohol Misuse Among Young Black Men Who Have Sex With Men in New York City.

Alcohol misuse is a significant health concern among gay, bisexual, same-gender-loving, and other men who have sex with men (MSM). Yet, little is known about the severity and predictors of alcohol misuse among self-reported young Black MSM. This study aimed to identify patterns of and factors associated with alcohol misuse in a sample of young Black MSM living in New York City. Baseline data from a randomized controlled trial aimed at improving the uptake of HIV testing among 250 MSM aged 18 to 29 were analyzed. Log-binominal regression analyses were conducted to assess the association of demographic and psychosocial factors with alcohol misuse in the past year and past 3 months among young Black MSM. Overall, 33.2% and 28.0% of young Black MSM in the study experienced alcohol misuse in the past year and past 3 months, respectively. In the adjusted model, factors positively associated with past-year alcohol misuse included marijuana use, a history of drug use, and having one-two or more than two male sex partners. Likewise, participants who used marijuana and those with one-two or more than two male partners were more likely to report past 3-month alcohol misuse. No significant association was found between positive screening for depressive symptoms, chemsex, internalized homophobia, and the likelihood of having alcohol misuse. The high prevalence of alcohol misuse underscores the importance of raising awareness of alcohol misuse and designing alcohol risk reduction programs that jointly address HIV risk among young Black MSM.

Adult cancer patients' barriers to and satisfaction with care at a National Cancer Hospital in Vietnam.

STUDY OBJECTIVE: This study assessed the overall satisfaction with oncological care, including barriers to care, and identified its associated predictors among adult cancer patients in Vietnam. METHODS: In this cross-sectional study, we enrolled 300 adult cancer patients receiving inpatient care at a large urban oncological hospital between June and July 2022. Multivariable linear regression analyses examined associations between patient experiences and overall satisfaction ratings with cancer care. RESULTS: The mean overall satisfaction with oncological care was 8.82 out of 10, with 98.0% recommending this facility to their friends and family. In an adjusted model, being female (ß = 0.29, 95%CI: 0.04, 0.53), endorsing satisfaction with patient-nurse communication (ß = 0.33, 95%CI: 0.13, 0.53), patient-doctor communication (ß = 0.40, 95%CI: 0.11, 0.70), and psychoeducation about oncological medication management (ß = 0.30, 95%CI: 0.14, 0.45) were positively associated with overall ratings. In contrast, individuals with delays in treatment scheduling reported lower overall satisfaction with oncological care (ß = -0.38, 95%CI: -0.64, -0.13). Patients perceived health system, social/environmental, and individual barriers to care: worries about income loss due to attending treatment (43.3%); fear, depression, anxiety, and distress (36.8%); concerns about affordability of treatment (36.7%) and transportation problems (36.7%); and excessive waiting times for appointments (28.8%). CONCLUSION: This study showed high overall patient satisfaction with cancer care quality. Patient-centered communication strategies and psychoeducation about oncological medication management may be targeted to further enhance the cancer inpatient experience. Raising awareness about treatment options and services, and integrating mental health awareness into oncological care may ameliorate patient distress and facilitate greater satisfaction with oncological treatment processes.

Mental Health Concerns During COVID-19: An Observational Study Among a Predominantly Black Community in New York City.

PURPOSE: This study examined the prevalence of mental health concerns and its association with COVID-19, selected social determinants of health, and psychosocial risk factors in a predominantly racial/ethnic minoritized neighborhood in New York City. METHODS: Adult Harlem residents (N = 393) completed an online cross-sectional survey from April to September 2021. The Patient Health Questionnaire (PHQ-4) and the Post-Traumatic Stress Disorder (PC-PTSD) were used to evaluate mental health concerns. Poisson regression with robust variance quantified the associations of interests via prevalence ratios (PR) and 95% confidence intervals (CI). RESULTS: Two-thirds (66.4%) of the residents reported experiencing mental health concerns, including PTSD (25.7%), depression (41.2%), and anxiety (48.1%). Residents with low-income housing status (PR = 1.16; 95% CI 1.01, 1.34), alcohol misuse (PR = 1.68; 95% CI 1.40, 2.01), food insecurity (PR = 1.23; 95% CI 1.07, 1.42), exposure to interpersonal violence (PR = 1.33; 95% CI 1.08, 2.65), and experience of discrimination (PR = 1.53, 95% CI 1.23-1.92) were more likely to report mental health concerns. Better community perception of the police (PR = 0.97, 95% CI 0.95, 0.99) was associated with fewer mental health concerns. No associations were observed for employment insecurity, housing insecurity, or household COVID-19 positivity with mental health concerns. CONCLUSIONS: This study showed a high prevalence of mental health concerns in a low-income racial/ethnic minoritized community, where COVID-19 and social risk factors compounded these concerns. Harlem residents face mental health risks including increased financial precarity, interpersonal violence, and discrimination exposure. Interventions are needed to address these concurrent mental health and psychosocial risk factors, particularly in racial/ethnic minoritized residents.

Mental Health Service Use, Barriers, and Service Preferences During COVID-19 among Low-Income Housing and Market-Rate Housing Residents of Harlem in New York City.

This study examined the differences in mental health service use, barriers, and service preferences among 393 low-income housing (LIH) and market-rate housing (MRH) Harlem residents in New York City. One-third (34.6%) endorsed the need for professional support for psychological issues, 27.2% and 15.8% reported using counseling services and psychotropic medication, with no differences between housing types. LIH residents (21.6-38.8%) reported significantly higher use of all types of mental health resources (e.g., websites, anonymous hotlines, self-help tools) compared with MRH residents (16.1-26.4%). Eighty-six percent reported barriers to mental health access, with LIH residents reporting more than double the barriers. Particularly, LIH residents reported greater difficulty getting time off work (34.1% vs. 14%), lack of health insurance (18.7% vs. 9.8%), lack of trust in mental health providers (14.6% vs. 4.7%), and stigma (12.2% vs. 5.1%) compared with MRH residents. Residents most preferred places of services were health clinics and houses of worship; provided by healthcare and mental health providers; and services delivered in-person and phone-based counseling. In contrast, residents least preferred getting support at mental health clinics; from family/friends; and by the Internet. No differences were found between service preferences by housing type. LIH residents reported higher use of mental health services and resources, but they face significantly more barriers to mental health care, suggesting a need to address specific barriers. Preferences for mental health services suggest a need for expanding mental health services to different settings given the low preference for services to be delivered at mental health clinics.

Population-based examination of substance use disorders and treatment use among US young adults in the National Survey on Drug Use and Health, 2011-2019.

Background: Compared with adults of other age groups, young adults are more likely to have substance use disorders (SUDs) but less likely to receive treatment. Untreated SUDs can lead to lethal consequences, particularly deaths related to drug overdose. Objectives: This study aimed to examine trends and sociodemographic differences in the prevalence and treatment use of SUDs among US young adults aged 18 to 25 in the National Survey on Drug Use and Health 2011-2019. Methods: Bivariable logistic regression analyses were conducted to examine annual changes in the prevalence and treatment use of SUDs, and multivariable logistic regression was used to examine sociodemographic differences in SUD prevalence and treatment use in the pooled sample of young adults from 2011 to 2019. Results: From 2011 to 2019, the overall SUD prevalence increased significantly from 5.4% to 6.2%. Cannabis use disorder was the most common SUD annually. Groups with lower prevalence of SUDs included females, young adults aged 22-25, and Hispanic, Black, and Asian participants. Across the survey years, the prevalence of treatment use fluctuated insignificantly between 10.9% and 16.9% among young adults with SUDs, and most young adults received SUD treatment in self-help groups and residential and outpatient rehabilitation facilities. Compared to White participants, treatment use was lower in Hispanic, Black, Asian participants, as well as young adults of two or more races. Young adults covered by Medicaid/CHIP were more likely to use treatment. Conclusions: This study revealed an alarming level of unmet treatment need and significant disparities in treatment use among young adults with SUDs. To reduce barriers to treatment utilization, more coordinated efforts that leverage policy and structural changes alongside innovations to engage young adults with SUD care are needed.

Demographic and ecological niche dynamics of the Vietnam warty newt, Paramesotriton deloustali: Historical climate influences.

Quaternary climatic cycles strongly affected the genetic diversification and ranges of organisms, shaping current genetic structures and distribution patterns. Urodeles provide ideal examples for exploring these dynamics over time and across space. In this study, we integrated a phylogeographic approach and ensemble species distribution modeling (eSDM) to infer the historical demography and distribution patterns of the Vietnam warty newt, Paramesotriton deloustali. Mitochondrial data revealed two groups, West and East, which diverged approximately 1.92 million years ago (Mya). Diversification was likely driven by change in the climate during early stages of the Pleistocene, with increasing monsoon and drought intensities. Biogeographic analysis indicated that the newt's current distribution formed as a result of vicariance events. In addition, the two groups occupy distinct ecological niches. Demographic reconstruction showed signs of expansion in the effective population sizes of the two major groups beginning around 0.11 and 0.15 Mya, respectively. However, eSDM showed fluctuating predicted distributions during the last interglacial, last glacial maximum, mid-Holocene, and present. Mountain systems in northern Vietnam are likely to have served as climatic refuges and to have played a crucial role in safeguarding species from the effects of climate change.

Passive acoustic monitoring using smartphones reveals an alarming gibbon decline in a protected area in the central Annamite Mountains, Vietnam.

Monitoring populations is critical for understanding how they respond to anthropogenic disturbance and for management of protected areas. The use of passive acoustic monitoring can improve monitoring efforts as it allows for collection of data on vocal animals at spatial and temporal scales that are difficult using only human observers. In this study, we used a multiseason occupancy model to monitor occurrence, apparent extinction, and colonization probabilities of a northern yellow-cheeked gibbon, Nomascus annamensis population with acoustic data collected from mobile smartphones in Dakrong Nature Reserve, Vietnam. Forty-five sites were randomly selected for repeated surveys in 2019 and 2022. At each site, a mobile smartphone was attached to a tree and recorded sounds for 4.2 days and 3.89 days on average, in 2019 and 2022, respectively. We manually annotated spectrograms for the presence of gibbon calls, and we detected gibbons at 24 and 12 recording posts in 2019 and 2022, respectively. Estimated local apparent extinction from occupancy models was high with 67% of occupied sites in 2019 becoming unoccupied in 2022. Apparent colonization was low with ~25% of unoccupied sites in 2019 becoming occupied in 2022. As a result, the apparent occurrence probability declined from 0.58 in 2019 to 0.30 in 2022. If the absence of calls indicates that cells are unoccupied this would mean an alarming decline of the gibbon population in the nature reserve. We suggest that in the areas with high hunting pressure, monitoring intervals should be shortened to at least yearly. In addition, urgent actions, such as patrolling, or gun confiscation, should be implemented to conserve the gibbon populations in Dakrong Nature Reserve and other protected areas with the same management context.

Study protocol for type II hybrid implementation-effectiveness trial of strategies for depression care task-sharing in community health stations in Vietnam: DEP Project.

BACKGROUND: It is not clear what the most effective implementation strategies are for supporting the enactment and sustainment of depression care services in primary care settings. This type-II Hybrid Implementation-Effectiveness study will compare the effectiveness of three system-level strategies for implementing depression care programs at 36 community health stations (CHSs) across 2 provinces in Vietnam. METHODS: In this cluster-randomized controlled trial, CHSs will be randomly assigned to one of three implementation conditions: (1) Usual Implementation (UI), which consists of training workshops and toolkits; (2) Enhanced Supervision (ES), which includes UI combined with bi-weekly/monthly supervision; and (3) Community-Engaged Learning Collaborative (CELC), which includes all components of ES, combined with bi-monthly province-wide learning collaborative meetings, during which cross-site learning and continuous quality improvement (QI) strategies are implemented to achieve better implementation outcomes. The primary outcome will be measured based on the RE-AIM framework (Reach, Effectiveness, Adoption, Implementation quality, and Maintenance) using indicators on implementation, provider, and client factors. The secondary outcome examines factors associated with barriers and facilitators of quality implementation, while the tertiary outcome evaluates the incremental cost-effectiveness ratio of services provided in the ES and CELC conditions, relative to UI condition for depression care. A total of 1,296 clients receiving depression care at CHSs will be surveyed at baseline and 6-month follow-up to assess mental health and psychosocial outcomes (e.g., depression and anxiety severity, health function, quality of life). Additionally, 180 CHS staff and 180 non-CHS staff will complete pre- and post-training evaluation and surveys at baseline, 6, 12, and 24 months. DISCUSSION: We hypothesize that the additional implementation supports will make mental health service implementation superior in the ES and CELC arms compared to the UI arm. The findings of this project could identify effective implementation models and assess the added value of specific QI strategies for implementing depression care in primary care settings in Vietnam, with implications and recommendations for other low- and middle-income settings. More importantly, this study will provide evidence for key stakeholders and policymakers to consider policies that disseminate, scale up, and advance quality mental health care in Vietnam.

Substance Use Patterns and Their Association with Depression and Social Factors During COVID-19 Among Harlem Residents in New York City.

This study aimed to identify the prevalence of substance use before and during COVID-19; and examined its association with depression and social factors among 437 residents from the neighborhood of Harlem in Northern Manhattan, New York City. Over a third of respondents reported using any substance before COVID-19, and initiating/increasing substance use during COVID-19. The most common substances used before COVID-19 and initiated/increased during COVID-19 were smoking (20.8% vs. 18.3%), marijuana (18.8% vs. 15.3%), and vaping (14.2% and 11.4%). The percentages of any hard drug use were 7.3% and 3.4%, respectively. After adjustment, residents with mild (Prevalence Ratio [PR] = 2.86, 95% CI 1.65, 4.92) and moderate (PR = 3.21, 95% CI 1.86, 5.56) symptoms of depression, and housing insecurity (PR = 1.47, 95% CI 1.12, 1.91) had at least a 47% greater probability of initiating and/or increasing substance use. Conversely, respondents with employment insecurity (PR = 0.71, 95% CI 0.57, 0.88) were 29% less likely to report such patterns. No association was found between substance use initiation and/or increase and food insecurity. High prevalence of substance use during COVID-19 may lead residents to turn to substance use as a coping mechanism for psychosocial stressors. Thus, it is essential to provide accessible and culturally sensitive mental health and substance use services.

Alcohol Misuse, Binge Drinking, and their Associations with Psychosocial Factors during COVID-19 among Harlem Residents in New York City.

This study examined alcohol misuse and binge drinking prevalence among Harlem residents, in New York City, and their associations with psycho-social factors such as substance use, depression symptom severity, and perception of community policing during COVID-19. An online cross-sectional study was conducted among 398 adult residents between April and September 2021. Participants with a score of at least 3 for females or at least 4 for males out of 12 on the Alcohol Use Disorders Identification Test were considered to have alcohol misuse. Binge drinking was defined as self-reporting having six or more drinks on one occasion. Modified Poisson regression models were used to examine associations. Results showed that 42.7% used alcohol before COVID-19, 69.1% used it during COVID-19, with 39% initiating or increasing alcohol use during COVID-19. Alcohol misuse and binge drinking prevalence during COVID-19 were 52.3% and 57.0%, respectively. Higher severity of depression symptomatology, history of drug use and smoking cigarettes, and experiencing housing insecurity were positively associated with both alcohol misuse and binge drinking. Lower satisfaction with community policing was only associated with alcohol misuse, while no significant associations were found between employment insecurity and food insecurity with alcohol misuse or binge drinking. The findings suggest that Harlem residents may have resorted to alcohol use as a coping mechanism to deal with the impacts of depression and social stressors during COVID-19. To mitigate alcohol misuse, improving access to mental health and substance use disorder services, and addressing public safety through improving relations with police could be beneficial.

Land-use change is associated with multi-century loss of elephant ecosystems in Asia.

Understanding historic patterns of land use and land cover change across large temporal and spatial scales is critical for developing effective biodiversity conservation management and policy. We quantify the extent and fragmentation of suitable habitat across the continental range of Asian elephants (Elephas maximus) based on present-day occurrence data and land-use variables between 850 and 2015 A.D. We found that following centuries of relative stability, over 64% (3.36 million km2) of suitable elephant habitat across Asia was lost since the year 1700, coincident with colonial-era land-use practices in South Asia and subsequent agricultural intensification in Southeast Asia. Average patch size dropped 83% from approximately 99,000-16,000 km2 and the area occupied by the largest patch decreased 83% from ~ 4 million km2 (45% of area) to 54,000 km2 (~ 7.5% of area). Whereas 100% of the area within 100 km of the current elephant range could have been considered suitable habitat in the year 1700, over half was unsuitable by 2015, driving potential conflict with people. These losses reflect long-term decline of non-forested ecosystems, exceeding estimates of deforestation within this century. Societies must consider ecological histories in addition to proximate threats to develop more just and sustainable land-use and conservation strategies.

Universal health insurance program for people living with HIV in Vietnam: an ambitious approach.

International funding for HIV treatment and prevention drastically decreased when Vietnam transitioned from a low-income to a lower-middle-income country in 2010. Vietnam has attempted to fill the funding gap from both public and private sources to cover antiretroviral therapy (ART) treatment. However, policies that enable social health insurance to pay for ART treatment-related costs often exclude people living with HIV (PLHIV) without appropriate government documents from accessing the health insurance-funded ART program. The Vietnamese Ministry of Health might consider alternative approaches, such as implementing a universal health insurance program among PLHIV regardless of residency or documentation status, to expand coverage of ART treatment to achieve the UNAIDS 95-95-95 targets by 2030. This expanded universal care will increase the uptake of ART treatment among uninsured PLHIV as well as increase coverage of health insurance-funded ART among insured PLHIV. Most importantly, the proposed insurance scheme could significantly improve population health by reducing HIV new infections and providing economic benefits of ART treatment through increased productivity and decreased healthcare costs.

Mental health, functional impairment, and barriers to mental health access among cancer patients in Vietnam.

OBJECTIVE: This study evaluated the prevalence and severity of depression and anxiety symptomatology, barriers to mental health access, and correlates of functional impairment among cancer inpatients. METHODS: This cross-sectional study recruited adult cancer patients (N = 300) in June and July 2022 at the largest oncological hospital in Vietnam. Multivariable linear regression analyses examined the association between demographics, clinical characteristics, and patients' functional impairment. RESULTS: Approximately 46.3% and 27.0% showed some depression and anxiety symptomatology, while 8.0% and 3.0% experienced major depressive and anxiety symptoms, respectively. Patients reported the most impairment in mobility and capacity for life activities. More functional impairment was identified in patients with gastrointestinal cancers, those receiving radiation therapy alone, and those scoring higher on depression and anxiety than in those with cancers originating in the head, neck, or lung or those receiving chemotherapy alone. Reports of better overall health status were negatively associated with functional impairment. Patients reported extensive perceived barriers to seeking psychiatric care, including not knowing where to get mental health support (86.7%), wanting to manage mental health independently (73.7%), and thinking mental health will resolve on its own (73.7%), and denying mental health concerns (61.0%). CONCLUSION: High frequency and severity of depression and anxiety symptomatology underscore the importance of integrating mental health services into existing oncological treatment protocols. Increasing mental health literacy and provision of psychoeducation is critical to addressing barriers to mental health service access. Integration of functional impairment evaluations into hospital admission and discharge planning is also needed.

Surgery After BRAF-Directed Therapy Is Associated with Improved Survival in BRAFV600E Mutant Anaplastic Thyroid Cancer: A Single-Center Retrospective Cohort Study.

Background: The aim of this study was to describe the oncologic outcomes of patients with BRAFV600E-mutated anaplastic thyroid cancer (ATC) who had neoadjuvant BRAF-directed therapy with subsequent surgery. For context, we also reviewed patients who received BRAF-directed therapy after surgery, and those who did not have surgery after BRAF-directed therapy. Methods: This was a single-center retrospective cohort study conducted at a tertiary care cancer center in Texas from 2017 to 2021. Fifty-seven consecutive patients with BRAFV600E-mutated ATC and at least 1 month of BRAF-directed therapy were included. Primary outcomes were overall survival (OS) and progression-free survival (PFS). Results: All patients had stage IVB (35%) or IVC (65%) ATC. Approximately 70% of patients treated with BRAF-directed therapy ultimately had surgical resection of residual disease. Patients who had neoadjuvant BRAF-directed therapy followed by surgery (n = 32) had 12-month OS of 93.6% [confidence interval (CI) 84.9-100] and PFS of 84.4% [CI 71.8-96.7]. Patients who had surgery before BRAF-directed therapy (n = 12) had 12-month OS of 74.1% [CI 48.7-99.5] and PFS of 50% [CI 21.7-78.3]. Finally, patients who did not receive surgery after BRAF-directed therapy (n = 13) had 12-month OS of 38.5% [CI 12.1-64.9] and PFS of 15.4% [CI 0-35.0]. Neoadjuvant BRAF-directed therapy reduced tumor size, extent of surgery, and surgical morbidity score. Subgroup analysis suggested that any residual ATC in the surgical specimen was associated with significantly worse 12-month OS and PFS (OS = 83.3% [CI 62.6-100], PFS = 61.5% [CI 35.1-88]) compared with patients with pathologic ATC complete response (OS = 100%, PFS = 100%). Conclusions: We observed that neoadjuvant BRAF-directed therapy reduced extent of surgery and surgical morbidity. While acknowledging potential selection bias, the 12-month OS rate appeared higher in patients who had BRAF-directed therapy followed by surgery as compared with BRAF-directed therapy without surgery; yet, it was not significantly different from surgery followed by BRAF-directed therapy. PFS appeared higher in patients treated with neoadjuvant BRAF-directed therapy relative to patients in the other groups. These promising results of neoadjuvant BRAF-directed therapy followed by surgery for BRAF-mutated ATC should be confirmed in prospective clinical trials.

A review on the status and modeling of suitable habitats of the southern white-cheeked gibbon.

The southern white-cheeked gibbon Nomascus siki is endemic to Indochina and is classified as critically endangered on the International Union for Conservation of Nature (IUCN) Red List. The most updated information on the status of this species dates back to a decade ago. As hunting has tremendous impacts on wildlife in Southeast Asia, the population of N. siki might have changed a lot in the last decade. Updated information on the status and potential distribution of this species is critically important for conservation and prioritization, especially for N. siki because of its undefined distribution range. The goal of this study was to review the population status of N. siki in Vietnam and Lao People's Democratic Republic (PDR) and to model its potential distribution. In Vietnam, this species has been intensively surveyed in all major areas of occurrence from 2016 to 2021. The total number of N. siki groups recorded and estimated in Vietnam were 324 and 483, respectively. In Lao PDR, the occurrence of N. siki has been confirmed in Nam Kading, Nakai Nam Theun, Hin Nam No, and Phou Hinpoun national protected areas. However, population estimates are generally lacking. The suitable habitat of N. siki was predicted from about 105.00° to 106.80° E longitude and from about 16.60° to 17.90° N latitude located in Quang Binh and Quang Tri provinces (Vietnam), and Khammounan and Savannakhet provinces (Lao PDR). The area of the potential distribution range is about 9894.15 km2, both in Vietnam and Lao PDR. Particularly, the high, medium, and low suitable habitats were estimated at around 1229.58 km2, 3019.68 km2, and 5644.89 km2, respectively. The area of suitable habitat of N. siki in Vietnam was predicted to be 4151.25 km2, of which only 1257.93 km2 (30.30%) is in the protected area network. Dong Chau-Khe Nuoc Trong and Bac Huong Hoa Nature Reserves, and Phong Nha-Ke Bang National Park should receive priority for conservation of N. siki in Vietnam. Improving conservation beyond the protected areas' boundaries or transforming the forest enterprises and watershed protection forests into protected areas should also be considered as an alternative for the conservation of N. siki. In Lao PDR, surveys of the species in its entire distribution range should be the first priority.

Perceived socially responsible HRM, employee organizational identification, and job performance: the moderating effect of perceived organizational response to a global crisis.

In an uncertain economy and a globalized world, socially responsible human resource management (HRM) is pivotal to the long-term growth of organizations. This research employed social exchange theory and social identity theory to analyze the correlations between employees' perceptions of socially responsible HRM, organizational identification, and job performance. This research also explored the moderating effect of employees' perceptions of their organization's response to a global crisis such as the COVID-19 pandemic on the relationship between organizational identification and job performance. Analyzing the survey data from 367 respondents using partial least squares structural equation modeling (PLS-SEM) with SmartPLS 3.2 software, this study found that HRM that is perceived to be socially responsible positively influences organizational identification and job performance. Moreover, the study found that organizational identification serves as a mediator between socially responsible HRM and work performance. It also revealed that perceived organizational response to a crisis such as the COVID-19 pandemic positively influences employees' job performance and negatively moderates the nexus between organizational identification and job performance. This study clarified the role of socially responsible HRM and organizational reactions to a crisis in promoting employee job performance.

Distinguishing Intrathyroid Parathyroid Adenoma from Colloid Nodules and Papillary Thyroid Carcinomas Using Multiphasic Multidetector Computed Tomography.

OBJECTIVE: The aim of the study is to determine whether multiphase multidetector computed tomography (4D-MDCT) can differentiate between intrathyroid parathyroid adenomas (ITPAs), colloid nodules, and papillary thyroid carcinoma (PTC). METHODS: We studied 22 ITPAs, 22 colloid nodules, and 11 PTCs in 55 patients. Hounsfield unit (HU) values of the nodules were measured on 4D-MDCT in the precontrast, arterial, venous, and delayed phases. Raw HU values, phase with peak enhancement, and washout percentages between the phases were evaluated. RESULTS: Regardless of size, all ITPAs (22/22) showed peak enhancement in the arterial phase, which was significantly greater than both colloid nodules (15/22) and PTC (6/11, P = 0.002); thus, nodules with peak enhancement in the venous or delayed phase were not ITPAs (specificity = 1). For nodules with peak enhancement in the arterial phase, the percentage washout in the arterial-to-venous phases separated ITPAs from PTC and colloid nodules (P < 0.001) with greater than or equal to 23.95% loss of HU value implying IPTA (area under curve, 0.79). This left a subset of colloid nodules or PTC that either peaked in the venous or delayed phase or had an arterial-to-venous phase washout of less than 23.95%. From this subset, PTC measuring 1 cm or greater could be separated from colloid based on HU values in the arterial phase with a cutoff HU value less than 81.4 for PTC (area under curve, 0.72) and an HU value greater than 164.5 suggested colloid. CONCLUSIONS: Intrathyroid parathyroid adenomas can be distinguished from colloid nodules and PTC by peak enhancement in the arterial phase and rapid washout. A subset of colloid and PTC measuring 1 cm or greater can be separated using arterial phase HU values.

Surgical Aspects of Primary Hyperparathyroidism.

Parathyroidectomy (PTX) is the treatment of choice for symptomatic primary hyperparathyroidism (PHPT). It is also the treatment of choice in asymptomatic PHPT with evidence for target organ involvement. This review updates surgical aspects of PHPT and proposes the following definitions based on international expert consensus: selective PTX (and reasons for conversion to an extended procedure), bilateral neck exploration for non-localized or multigland disease, subtotal PTX, total PTX with immediate or delayed autotransplantation, and transcervical thymectomy and extended en bloc PTX for parathyroid carcinoma. The systematic literature reviews discussed covered (i) the use of intraoperative PTH (ioPTH) for localized single-gland disease and (ii) the management of low BMD after PTX. Updates based on prospective observational studies are presented concerning PTX for multigland disease and hereditary PHPT syndromes, histopathology, intraoperative adjuncts, localization techniques, perioperative management, "reoperative" surgery and volume/outcome data. Postoperative complications are few and uncommon (<3%) in centers performing over 40 PTXs per year. This review is the first global consensus about surgery in PHPT and reflects the current practice in leading endocrine surgery units worldwide. © 2022 The Authors.

Self-Determination Theory and Accountant Employees' Psychological Wellbeing: The Roles of Positive Affectivity and Psychological Safety.

This study investigates the influence of self-determination motivations on accountant employees' psychological wellbeing with the mediating role of positive affectivity and the moderating role of psychological safety. Multivariate analysis and structural equation modeling are used to analyze a three-way time-lagged sample data of 391 accountant employees. Results indicate that positive affectivity positively mediates the relationship between extrinsic motivation and psychological wellbeing and between intrinsic motivation and psychological wellbeing. Furthermore, psychological safety positively moderates the relationship between extrinsic motivation and positive affectivity and between intrinsic motivation and positive affectivity. In addition, psychological safety also positively moderates the relationship between positive affectivity and psychological wellbeing. The findings of this study provide implications for researchers and business managers in managing and enhancing accountant employees' psychological wellbeing.
