ABSTRACT

Self-determination theory holds that the intrinsic and extrinsic content of people’s aspirations differentially affect their wellness. An evidence base spanning nearly 30 years indicates that focusing on intrinsic goals (such as for growth, relationships, community giving, and health) promotes well-being, whereas a focus on extrinsic goals (such as for wealth, fame, and beauty) deters well-being. Yet, the evidence base contains exceptions, and some authors have argued that focusing on extrinsic goals may not be universally detrimental. We conducted a systematic review and used multilevel meta-analytic structural equation modeling to evaluate the links between intrinsic and extrinsic aspirations with indices of well-being and ill-being. Across 92 reports (105 studies), 1,808 effects, and a total sample of N = 70,110, we found that intrinsic aspirations were linked positively with well-being, r = 0.24 [95% CI 0.22, 0.27], and negatively with ill-being, r = -0.11 [-0.14, -0.08]. When the variety of extrinsic aspiration scoring methods were combined, the link with well-being was not statistically significant, r = 0.02 [-0.02, 0.06]. However, when extrinsic aspirations were evaluated in terms of their predominance in the overall pattern of aspiring the effect was universally detrimental, linking negatively to well-being, r = -0.22 [-0.32, -0.11], and positively to ill-being, r = 0.23 [0.17, 0.30]. Meta-analytic conclusions about the associations between goal types and wellness are important because they inform how individuals could shape aspirations to support their own happiness and how groups and institutions can frame goals such that their pursuit is for the common good.

ABSTRACT

BACKGROUND: While iron is essential for normal brain functioning, elevated concentrations are commonly found in neurodegenerative diseases and are associated with impaired cognition and neurological deficits. Currently, only little is known about genetic and environmental factors that influence brain iron concentrations.

METHODS: Heritability and bivariate heritability of regional brain iron concentrations, assessed by R2* relaxometry at 3 Tesla MRI, were estimated with variance components models in 130 middle-aged to elderly participants of the Austrian Stroke Prevention Family Study.

RESULTS: Heritability of R2* iron ranged from 0.46 to 0.82 in basal ganglia and from 0.65 to 0.76 in cortical lobes. Age and BMI explained up to 12% and 9% of the variance of R2* iron, while APOE ε4 carrier status, hypertension, diabetes, hypercholesterolemia, sex and smoking explained 5% or less. The genetic correlation of R2* iron among basal ganglionic nuclei and among cortical lobes ranged from 0.78 to 0.87 and from 0.65 to 0.97, respectively. R2* rates in basal ganglia and cortex were not genetically correlated.

CONCLUSIONS: Regional brain iron concentrations are mainly driven by genetic factors while environmental factors contribute to a certain extent. Brain iron levels in the basal ganglia and cortex are controlled by distinct sets of genes.

ABSTRACT

While the continent of Africa currently has the lowest share of adults ages 60 and older in its population among all world regions, the total number of older Africans is projected to triple between 2020 and 2050. Nigeria-Africa’s leading economy and most populated country-has the highest number of older people in the continent and the 19th highest across the globe, with the population of Nigerians aged 65 and older projected to nearly triple by 2050. However, the increase in older Nigerians is occurring against the backdrop of extreme poverty, unsolved development problems, socioeconomic inequality, the HIV/AIDS epidemic, and a decline in the traditional care and support of older adults. Additionally, the absence of an operational national aging policy or safety net services and programs poses a unique challenge to older Nigerians and their families. In this paper, we examined social statistics and the current literature to describe aging in the Nigerian context. Our findings highlight the importance of establishing effective governmental policy interventions for the adequate care and support of older Nigerians and the training of gerontological professionals. This paper will describe the demography of aging in Nigeria, significant areas of research, key scholars and publicly available datasets, public policy issues, and emerging issues affecting the health and well-being of older Nigerians.

ABSTRACT

Anecdotal evidence indicates there may be unpublished physical and psychological events associated with the medical treatment of plutonium intakes. A thorough review was conducted of the medical and bioassay records of current and previous Los Alamos National Laboratory (LANL) employees who had experienced plutonium intakes via wound or inhalation. After finding relatively incomplete information in the medical records, the research team interviewed current LANL employees who had undergone chelation therapy and/or surgical excision. Although the dataset is not large enough to reach statistically significant conclusions, it was observed that adverse events associated with treatment appear to be more frequent and more severe than previously reported.

ABSTRACT

IMPORTANCE: Individuals with severe obesity presenting for obesity surgery (OS) frequently show nonnormative eating behaviors (NEBs) and eating disorders (EDs), but the long-term course and prospective associations with weight loss and health-related quality of life (HRQOL) remain unclear.

OBJECTIVE: To examine the prevalence and prospective relevance of presurgical and postsurgical NEBs and EDs according to the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, diagnosed through clinical interview, for weight loss and HRQOL up to 6 years following OS.

DESIGN, SETTING, AND PARTICIPANTS: In the prospective, multicenter Psychosocial Registry for Obesity Surgery cohort study, patients seeking OS were recruited at 6 OS centers in Germany and assessed at baseline before surgery and at 6 months and 1 to 6 years after surgery. From a consecutive sample of 1040 volunteers with planned OS from March 1, 2012, to December 31, 2020, a total of 748 (71.92%) were included in this study. Across follow-up, 93 of the 748 patients (12.43%) dropped out. Data were analyzed from April to November 2021.

INTERVENTIONS: Laparoscopic Roux-en-Y gastric bypass or sleeve gastrectomy.

MAIN OUTCOMES AND MEASURES: Both NEBs and EDs were identified using the Eating Disorder Examination interview. Main outcomes were the percentage of total body weight loss (%TBWL) and HRQOL (Impact of Weight on Quality of Life-Lite; range, 0-100, with 0 indicating worst and 100 indicating best).

RESULTS: In 748 patients undergoing OS (mean [SD] age, 46.26 [11.44] years; mean [SD] body mass index [calculated as weight in kilograms divided by height in meters squared], 48.38 [8.09]; 513 [68.58%] female), the mean (SD) %TBWL was 26.70% (9.61%), and the mean (SD) HRQOL improvement was 35.41 (20.63) percentage points across follow-up. Both NEBs and EDs were common before surgery, with postsurgical improvements of varying degrees. Whereas NEBs and EDs did not reveal significant prospective associations with %TBWL, loss-of-control eating at follow-up was concurrently associated with lower %TBWL (estimate, -0.09; 95% CI, -0.14 to -0.04). Loss-of-control eating (estimate, -0.10; 95% CI, -0.17 to -0.03 percentage points) and binge-eating disorder of low frequency and/or limited duration (estimate, -6.51; 95% CI, -12.69 to -0.34 percentage points) at follow-up showed significant prospective associations with lower HRQOL.

CONCLUSIONS AND RELEVANCE: This cohort study found prospective relevance of loss-of-control eating and binge-eating disorder of low frequency and/or limited duration for reduced long-term HRQOL following OS. These findings underline the importance of monitoring both NEBs, especially loss-of-control eating, and EDs in the long term postsurgically to identify patients in need of targeted prevention or psychotherapy.

ABSTRACT

IMPORTANCE: Taxane-based chemotherapy agents, such as docetaxel and paclitaxel, are used for treating a wide range of cancers. Although much has been published on adverse events related to taxanes, data on ocular outcomes with these very important drugs are scant.

OBJECTIVE: To quantify the risk of 3 mutually exclusive ocular adverse events of epiphora, cystoid macular edema (CME), and optic neuropathy with taxane-based chemotherapy agents by undertaking a large pharmacoepidemiologic study.

DESIGN, SETTING, AND PARTICIPANTS: This retrospective cohort study design used a private health-claims database from the US that captures health information of more than 150 million enrollees. The study team created a cohort of new users of women with cancer who were taking taxane-based chemotherapy (docetaxel or paclitaxel) and new users of tamoxifen as controls. Study members were observed to the first incidence of each of the 3 mutually exclusive outcomes. An analysis of taxane-only users was also undertaken.

EXPOSURE: Tamoxifen (unexposed) and taxanes (ie, paclitaxel and docetaxel) as the exposed.

MAIN OUTCOMES AND MEASURES: First diagnosis of (1) epiphora, (2) cystoid macular edema (CME), or (3) optic neuropathy ascertained using International Statistical Classification of Diseases and Related Health Problems, Ninth Revision or International Statistical Classification of Diseases and Related Health Problems, Tenth Revision.

RESULTS: Among the 18 219 users in the epiphora analysis and optic neuropathy analysis, there were 1824 taxane users (paclitaxel and docetaxel) (age, mean [SD], 62.1 [12.7] years) and 16 395 tamoxifen users (age, mean [SD], 54.6 [12.8] years), respectively. The crude hazard ratio (HR) for epiphora was 5.55 (95% CI, 2.99-10.29) and adjusted HR was 5.15 (95% CI, 2.79-9.54). For optic neuropathy, the crude HR was 4.43 (95% CI, 1.10-17.82) and the adjusted HR was 4.44 (95% CI, 1.04-18.87). Among the 18 433 users in the CME analysis, there were 1909 taxane users (paclitaxel and docetaxel) (age, mean [SD], 62.5 years) and 16 524 tamoxifen users (age, mean [SD], 54.6 years). The crude HR for CME comparing taxane users with tamoxifen users was 1.37 (95% CI, 0.72-2.60) and adjusted HR was 1.33 (95% CI, 0.70-2.53). The HRs for epiphora and CME in the taxane cohort during the time of exposure compared with the period prior to use of the drugs were 2.86 (95% CI, 1.11-7.39) and 2.27 (95% CI, 0.68-7.54), respectively.

CONCLUSIONS AND RELEVANCE: In a cohort of women who were using taxane chemotherapy agents, there was an association with elevated risk for epiphora, CME, and optic neuropathy. Ophthalmologists and oncologists should be aware of these adverse events in women with breast cancer who receive these drugs.

ABSTRACT

IMPORTANCE: Obstructive sleep apnea (OSA) is associated with a rise in serum inflammatory markers, which may be attenuated by sleep surgery.

OBJECTIVE: To evaluate whether sleep surgery was associated with improved levels of proinflammatory markers in adults with OSA.

DATA SOURCES: Two authors independently searched Cochrane, Embase, and PubMed databases from inception through June 14, 2022.

STUDY SELECTION: Two authors searched the Cochrane, Embase, and PubMed databases for studies comparing preoperative and postoperative levels of serum biomarkers in patients undergoing sleep surgery.

DATA EXTRACTION AND SYNTHESIS: Data were extracted from included articles into a structured proforma. Meta-analyses of the standardized mean difference (SMD) were conducted in random-effects models. To ensure relevance to clinicians and patients, the probability of benefit and number needed to treat were calculated for outcomes that demonstrated a statistically significant effect after sleep surgery.

MAIN OUTCOMES AND MEASURES: The primary outcome was the preoperative and postoperative levels of serum biomarkers in patients undergoing sleep surgery, including C-reactive protein (CRP), glucose, low-density lipoprotein (LDL), high-density lipoprotein (HDL), and interleukin-6 (IL-6). Data analysis was performed from April to May 2022.

RESULTS: Of the 3218 studies screened, 26 studies with 1187 patients (mean [SD] age, 42.8 [11.1] years; 932 [78.5%] men and 255 [21.5%] women) were included. Soft-tissue sleep surgery was associated with a large decrease in CRP (SMD, -0.377; 95% CI, -0.617 to -0.137), total cholesterol (SMD, -0.267; 95% CI, -0.417 to -0.116), LDL (SMD, -0.201; 95% CI, -0.344 to -0.058), IL-6 (SMD, -1.086; 95% CI, -1.952 to -0.221), tumor necrosis factor-α (SMD, -0.822; 95% CI, -1.617 to -0.027), triglyceride (SMD, -0.186; 95% CI, -0.301 to -0.071), and leptin (SMD, -0.519; 95% CI, -0.954 to -0.083) in patients with OSA. Meta-regression highlighted that increased age, higher preoperative score for cumulative sleep time percentage with oxyhemoglobin saturation less than 90% (CT90), and greater change in CT90 postoperatively were associated with a greater decrease in serum CRP levels after soft-tissue sleep surgery. A greater reduction in apnea hypopnea index (AHI) was strongly associated with a greater reduction in total cholesterol and LDL. A greater reduction in body mass index and AHI were also associated with a greater increase in HDL.

CONCLUSIONS AND RELEVANCE: The findings of this systematic review and meta-analysis of 26 studies suggest that sleep surgery is associated with decreased levels of CRP, total cholesterol, LDL, triglyceride, IL-6, leptin, and TNF-α, which may improve the inflammatory and cardiometabolic profile of patients who undergo sleep surgery.

ABSTRACT

OBJECTIVE: The relationships between temporomandibular disorders (TMDs) and negative affectivity/emotions across cultures and the emotional predictors for TMDs in Southeast Asian youths were investigated.

METHODS: The presence of TMDs and negative affectivity/emotions were determined with the Fonseca Anamnestic Index (FAI) and Depression, Anxiety, Stress Scales-21 (DASS-21). Statistical evaluations were done with non-parametric and logistic regression analyses (α.

RESULTS: The total sample comprised 400 Singaporean and 501 Indonesian youths (mean age 19.30 ± 1.48 years; 65.0% women) of whom 47.0% and 59.3% had mild-to-severe TMDs, respectively. For both cultures, participants with TMDs had significantly greater negative affectivity, depression, anxiety, and stress than those with no TMDs. Indonesian youths also presented higher levels of emotional distress than their Singaporean counterparts. Correlations between FAI and anxiety/stress scores were moderately strong.

CONCLUSION: Cultural variations can influence the expression of TMDs and emotional distress. Being female and anxious increased the risk of TMDs.

ABSTRACT

OBJECTIVE: Histopathological analysis of the relationship between penile elastography and erectile dysfunction.

MATERIAL AND METHOD: 12 patients who applied to our clinic for erectile dysfunction in the last 1 year and accepted this study were included. Preoperative two-dimensional shear wave elastography imaging was performed in 12 patients and recorded in the Pascal (kPa) unit. Approximately 0.5 × 0.5 × 0.5 cm tissue samples were taken from the right and left cavernous tissue during penile prosthesis implantation operation. Tissue samples were sent to the pathology department. The percentage of the area covered by muscle fibers and elastic fibers in the corpus cavernosum was noted semi-quantitatively (ratio of muscle fibers and cavernous body elastic fiber score). All data obtained were compared with each other.

RESULTS: Cavernous body elastic fiber score data(Grouped Score 1, 2 and 3) and percentage of cavernous body muscle fibers data (Grouped %10, %20, %30… %100) were compared with Shear wave elastography data (kPa). The results were not statistically significant according to the Kruskal Wallis Test. Cavernous body elastic fiber score and the percentage of cavernous body muscle fibers were also compared, it was not statistically significant according to the Kruskal Wallis test and Spearman’s correlation test.

CONCLUSIONS: Penile shear wave elastography can be used clinically to quantitatively assess the amount of smooth muscle cells and elastic fibers in the penis, but it deserves to be studied with a larger number of patients and a more specific interpretation of the pathology preparation.

ABSTRACT

BACKGROUND: Pleomorphic xanthoastrocytoma (PXA) is a rare low-grade brain tumor. To date, limited studies have analyzed factors affecting survival outcomes and defined the therapeutic strategy. The aim of this retrospective analysis was to investigate the clinicopathologic characteristics of PXA and identify factors associated with outcomes.

METHODS: We retrospectively analyzed a cohort of 16 adult and children patients with PXA who underwent primary resection from 1997 to 2019, referred to our Radiation Oncology Unit and to Meyer’s Paediatric Hospital. We also reviewed the relevant literature.

RESULTS: All patients underwent primary surgical resection; 10 patients received adjuvant radiation treatment course, ranging from DTF 54 to 64 Gy; 8 of them received, in addition, concurrent adjuvant chemotherapy; 6 patients underwent only radiological follow-up. After a median follow up was 60 months: median OS was 34.9 months (95% CI 30-218), 1-year OS 87%, 5-years OS 50%, 10-years OS 50%; median PFS 24.4 months (95% CI 13-156), 1-year PFS 80%, 5-years PFS 33%, 10-years PFS 33%. A chi-square test showed a significant association between OS and recurrent disease (p = 0.002) and with chemotherapy adjuvant treatment (p = 0.049). A borderline statistical significant association was instead recognized with BRAF mutation (p = 0.058).

CONCLUSIONS: Despite our analysis did not reveal a strong prognostic or predictive factor able to address pleomorphic xanthoastrocytoma management; however, in selected patients could be considered the addition of adjuvant radiation chemotherapy treatment after adequate neurosurgical primary resection. Furthermore, recurrent disease evidenced a detrimental impact on survival.
