The Role of Cultural and Family Values on Social Connectedness and Loneliness among Ethnic Minority Elders

Objectives: Ethnic minority elders have high levels of social isolation and loneliness. Assumptions about the family providing enough social support exist in the literature, contradicting ethnic minority elders’ reported levels of isolation and loneliness. While structural barriers influence feelings of isolation and loneliness, limited information exists about the role of cultural factors such as acculturation and family values. Accordingly, this study investigated the roles of acculturation and family values on loneliness and social isolation among ethnic minority elders.

Methods: Ethnic minority elders (N = 123) completed a questionnaire that assessed their social connectedness, measured by social network and levels of loneliness, and structural factors such as income. Additionally, cultural and family values were assessed by acculturation and the ‘family as referents’ dimension of familism, which refers to the belief that family members’ behaviour should meet with familial expectations.

Results: Statistical analysis using hierarchical regression indicated that ‘family as referents’ and acculturation predicted loneliness, but not social network.

Conclusions: This study raises the importance of considering cultural values when investigating predictors of loneliness among ethnic minority elders.

Clinical Implications: Findings highlight the importance of addressing familial expectations in programs aimed at alleviating loneliness among ethnic minority elders.     

Follow up on atopy and the gastrointestinal tract – a review of a common association 2018

Introduction: Primary atopic disorders can be classified as heritable genetic disorders presenting with deregulated pathogenic allergic effector responses irrespective of sensitization. In the last decade, there are parallel rises in the burden of atopic and gastrointestinal (GI) diseases.

Areas covered: There is increasing recognition of an association between atopy and GI disease through immune dysregulation, the microbiome and shared genetic pathways. Since the first article on atopy and the GI tract in 2014 in this journal, many more studies have shed light on the shared pathways in these diseases, particularly in the field of eosinophilic GI disease, functional GI disorders, and inflammatory bowel disease.

Expert opinion: Understanding the links with common mechanisms in atopy and GI diseases that may lead to better targeting of treatment through manipulation of immune mechanisms, the microbiome, genetics, food allergens and specific GI diseases such as inflammatory bowel disease, functional GI disorders.     

Depression and risky alcohol use: an examination of the role of difficulties regulating positive emotions in trauma-exposed individuals

Background: The co-occurrence of depression and risky alcohol use is clinically relevant given their high rates of comorbidity and reciprocal negative impact on outcomes. Emotion dysregulation is one factor that has been shown to underlie this association. However, literature in this area has been limited in its exclusive focus on emotion dysregulation stemming from negative emotions.

Objectives: The goal of the current study was to extend research by exploring the role of difficulties regulating positive emotions in depression symptom severity, risky alcohol use, and their association.

Methods: Participants were 395 trauma-exposed adults recruited from Amazon’s Mechanical Turk (MTurk) platform (56.20% female, M_age = 35.55) who completed self-report questionnaires.

Results: Zero-order correlations among depression symptom severity, the three subscales of difficulties regulating positive emotions, and risky alcohol use were positive. Two subscales of difficulties regulating positive emotions—nonacceptance of positive emotions and difficulties controlling impulsive behavior when experiencing positive emotions—accounted for the relationship between depression symptom severity and risky alcohol use.

Conclusion: Results suggest the importance of incorporating techniques focused on improving positive emotion regulation skills in interventions for risky alcohol use among individuals with depression.     

Trends in hepatocellular carcinoma due to non-alcoholic fatty liver disease

Introduction: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease worldwide and is associated with hepatocellular carcinoma (HCC), the most frequent malignant liver tumor. The increasing prevalence of obesity and diabetes is influencing the epidemiology of HCC with the most dramatic increases in NAFLD-related HCC seen in Western countries. Although cirrhosis is the major risk factor for HCC in NAFLD, there is increasing recognition that NAFLD-HCC occurs in the absence of cirrhosis.

Areas covered: The epidemiology of NAFLD related HCC and its impact on changing the incidence of HCC globally. We overview risk factors for NAFLD-HCC in the presence and absence of cirrhosis and examine trends in liver transplantation (LT) related to NAFLD-HCC.

Expert commentary: The incidence of NAFLD-related cirrhosis will continue to rise globally in parallel with risk factors of obesity and diabetes. Consequently, NAFLD-related HCC will become an increasingly important cause of liver-related morbidity and mortality and a common indication for LT worldwide. Further identification of risk factors for NAFLD-HCC and effective treatments for NAFLD are required to reduce this future burden of disease.     

Urban–rural environmental exposure during childhood and subsequent risk of inflammatory bowel disease: a meta-analysis

Background: The relationship between living conditions in urban and rural areas during childhood and subsequent inflammatory bowel disease (IBD) remains controversial.

Aim: To explore the association between environmental exposures early in life and the subsequent risk of IBD.

Methods: Literature searches were conducted in the following databases: PubMed, EMBASE, and Conference Proceedings Citation Index. Studies were analyzed separately using rate ratios (RRs) or odds ratios (ORs) with 95% confidence intervals.

Results: The search strategy identified 15 studies. Of these, 9 studies explored the association between urban exposure during childhood and ulcerative colitis (UC), and 12 and 4 studies explored this relationship with Crohn’s disease (CD) and IBD, respectively. A meta-analysis showed that the pooled ORs estimated for the case–control studies of UC, CD, and IBD were 1.16 (0.83, 1.61), 1.45 (1.45, 1.85), and 1.34 (1.11, 1.62), respectively. The pooled RR estimated for the cohort studies of CD and IBD was 1.48 (1.17, 1.87). The stratified analysis and meta-regression showed significant relationships between CD and living conditions in case–control studies published during 2010–2017 and in non-European countries (P < 0.05).

Conclusions: Living conditions during childhood are positively associated with the subsequent development of IBD. Urban living environment is more common among those with CD than UC.     

Invariance of a recovery capital scale across gender,ethnicity, and sexual orientation in a substance use disorder treatment program

Background: Behavioral health care providers aim to see their clients achieve lifelong recovery from substance use disorders (SUDs). To do so, they must accurately assess incoming resources and barriers to recovery to identify areas of need for their clients. A recovery capital scale (RCS) is one way to identify these resources and barriers. However, there is limited evidence that RCSs are invariant across different demographics.

Objectives: To evaluate whether a short 10-item RCS (SRCS-10) is invariant across gender (male versus female), ethnicity (white versus African American, Hispanic, and other racial identities) and sexual orientation (heterosexual versus non-heterosexual).

Methods: The SRCS-10 is a shortened version of White’s original unpublished 35-item RCS scale that was matched on items similar to the Brief Assessment of Recovery Capital (BARC-10). We used confirmatory factor analysis (CFA) to confirm unidimensionality and then conducted measurement invariance tests.

Results: This study included 2751 females (67%) and 1341 males (33%) totaling 4092 clients from six large residential treatment centers. Using both exploratory factor analysis (EFA) and CFA the SRCS-10 has a large first to second eigenvalue ratio and had a CFI and TLI close to and above .9 with an SRMR of below .05 and an omega of .85. Additionally, we saw limited changes in key indicators such as the CFI and RMSEA across gender, race, and sexual orientation.

Conclusions: These findings provide evidence that the SRCS-10 is a valid and reliable assessment across gender, race, and sexual orientation.     

Reference intervals of aortic pulse wave velocity assessed with an oscillometric device in healthy children and adolescents from Argentina

Age-related reference intervals (RIs) of aortic pulse wave velocity (Ao-PWV) obtained from a large healthy population are lacking in South America. The aims of this study were to determine Ao-PWV RIs in a cohort of healthy children and adolescents from Argentina and to generate year-to-year percentile curves.

Ao-PWV was measured in 1000 healthy subjects non-exposed to traditional cardiovascular risk factors (Age: 10–22 y. o., 56% males). First, we evaluated if RIs for males and females were necessaries (correlation and covariate analysis). Second, mean (M) and standard deviation (SD) age-related equations were obtained for cf-PWV, using parametric regression methods based on fractional polynomials. Third, age-specific (year to year) percentiles curves (for all, males and females children and adolescents) were generated using the standard normal distribution. They were, age-specific 1st, 2.5th, 5th, 10th, 25th, 50th, 75th, 90th, 95th, 97.5th and 99th percentile curves and values.

After covariate analysis (i.e., adjusting by age, jugulum-symphysis distance, body weight and height), specific RIs for males and females of children and adolescents were evidenced as necessaries. The equations were

For all subjects:

Ao-PWV_Mean = 4.98 + 12.86x10^?5 Age³.

Ao-PWV_SD = 0.47 + 21.00x10^?6Age³.

For girls:

Ao-PWV_Mean = 5.07 + 10.23x10^?5Age³.

Ao-PWV_SD = 0.50 + 10.00x10^?6Age³.

For boys:

Ao-PWV_Mean = 4.87 + 15.81x10^?5Age³.

Ao-PWV_SD = 0.46 + 22.34x10^?6Age³.

Our study provides the largest database to-date concerning Ao-PWV in healthy children and adolescents in Argentina. Age-related equations (M and SD values) for Ao-PWV are reported by the first time. Specific RIs and percentiles of Ao-PWV are now available according to age and sex for an Argentinian population.     

Intergenerational Ambivalence and Dyadic Strain: Understanding Stress in Family Care Partners of Older Adults

Objectives: The present study used Pearlin, Mullan, Semple & Skaff's (1990) caregiving stress process model as a framework to examine the comparative influence of two stressors: (a) intergenerational ambivalence as a unified construct and (b) dyadic strain, which is one isolated component of intergenerational ambivalence.

Methods: Participants were 120 women providing healthcare and medication assistance to an earlier generation family member with physical and/or cognitive impairments.

Results: Hierarchical regression confirmed that intergenerational ambivalence explained perceived stress in family care partners, beyond the variance accounted for by other commonly reported stressors such as length of caregiving experience, memory/cognitive and functional impairments of the care recipient, caregiver overload, family conflict and financial strain. Further analyses revealed that examining dyadic strain apart from intergenerational ambivalence may more accurately explain the influence of ambivalence scores on care partners’ perceived stress.

Conclusions and Clinical Implications: The comparative influence of dyadic strain versus ambivalence suggests that stress-reducing interventions may benefit from a focus on reducing care partners’ experiences of negative strain in the dyadic relationship rather than managing ambivalence.     

Providing Assistance for Older Adult Financial Exploitation Victims: Implications for Clinical Gerontologists

Background and Objective: Despite the growth of financial exploitation research in the past decade, almost none has focused on older urban adults, and especially urban African Americans. The Success After Financial Exploitation (SAFE) program provides individual financial coaching to older urban adults.

Methods: We use community education, delivered separately to older adults and to the professionals who serve them, to raise awareness about financial exploitation (FE) and to motivate referrals for financial coaching. This paper describes the program and methodology, and uses case examples and preliminary research to investigate the intersection of FE and physical and mental health functioning.

Results: SAFE participants were able to repair their credit scores, reduce new financial burdens, and even recover monies they had lost due to FE. Case examples illustrate how financial scams and identity theft impacts urban older adults. Participants were assessed prior to the provision of services, and SAFE participants performed poorer on executive functioning tasks than participants in the control group. They also reported more physical health problems and anxiety and depressive symptoms. SAFE participants also had significantly higher risk scores on a financial decision-making scale.

Conclusion: Study findings advance our understanding of the impacts of FE on cognitive functioning, mental health, and financial decision-making.

Clinical Implications: Clinicians need to be more attuned to the financial health of their older clients, who, if they are struggling with financial exploitation, may also be suffering from problems with cognitive functioning and physical and mental health.     

Comparing the effectiveness of biological disease-modifying antirheumatic drugs using real-world data

Objectives: The objective of this study is to compare the effectiveness of biological disease-modifying antirheumatic drugs (bDMARDs) by analyzing claims data of 13 Japanese national university hospitals.

Methods: We evaluated 4970 cases of rheumatoid arthritis treated with bDMARDs from the Clinical Information Statistical Analysis database, which has collected and integrated 13 Japanese national university hospitals’ claims data for 10 years. We surveyed the medications and calculated the retention rates of bDMARDs using the Kaplan–Meier method and differentiated the effectiveness between the two bDMARDs by comparing the retention rates after switching from one drug to another.

Results: Of the 4970 cases, 1364 switched bDMARDs at least once. Tocilizumab (TCZ) reported the highest retention rate, whereas abatacept (ABT) revealed a similar rate compared with only naïve cases. The retention rate curves were higher in cases on TCZ that switched from the other bDMARDs than those in the reversed cases. Following TCZ, ABT and etanercept indicated better results than the other bDMARDs.

Conclusion: We could compare the effectiveness among bDMARDs by differentiating the retention rates from big claims data. TCZ reported higher retention rates in both naïve and switched cases than other bDMARDs.     

Collagenous colitis without diarrhoea at diagnosis – a follow up study

Objective: Chronic watery diarrhoea is a classical symptom of collagenous colitis (CC). However, in some cases, the typical histologic findings of CC can be found in patients without this symptom. In this study we have performed a follow up on patients with a confirmed histological diagnosis of CC without the typical symptom watery diarrhoea.

Patients and methods: A structured medical record follow-up was performed on the subgroup of patients without watery diarrhoea but diagnosed with the typical CC histologic appearance in a previous study of microscopic colitis.

Results: At follow up after a median time of 8 years (range: 0.33–12 years), five of these fifteen patients developed bowel symptoms but only two developed characteristic CC symptoms with watery diarrhoea.

Conclusion: The majority of patients without chronic watery diarrhoea at diagnosis remained free from this symptom during follow up and only in a few cases symptoms attributed to CC developed.     

Clinical pertinence of neutrophil-to- lymphocyte ratio among hypertensives with different grades and duration of hypertension – an insight

Over the recent years, the pathophysiology of the inflammatory component in hypertension has been a challenge, because this inflammatory response is mainly contributed by an increased oxidative stress with the release of inflammatory mediators. Identification of a simple and early inflammatory marker such as the neutrophil-to-lymphocyte ratio (NLR) is the need of the hour. This study correlates the same specifically taking into account the duration and the grades of hypertension.

Objective: The response of the NLR among the hypertensives and its correlation with duration and stages of hypertension.

Method: Totally, 80 subjects and 40 controls of age between 20 and 60 years and both genders were included. Three recordings of blood pressure were measured with a standard mercury sphygmomanometer. The differential leukocyte count was estimated with an automated Beckman Coulter.

Objective: Variations in the neutrophil and lymphocyte counts were significant among the hypertensives with a p-value < 0.001. The NLR was also significantly altered among the hypertensives with a p-value = 0.001. The NLR showed a rise in value among the normotensives, prehypertensives, and stage 1 of systolic hypertension, though not statistically significant. An increase in the NLR was observed in hypertensives with duration of 1–2 years.

Conclusion: Our study gives a new insight with a rise in NLR in early years and even among prehypertensives and stage 1 systolic hypertension under strict criterion. This could be utilized as an early predictive tool, relating the inflammatory process and hypertension which on further intervention could slow the progression of the disease process.

Abbreviations: NLR: Neutrophil-to-lymphocyte ratio; BP: Blood pressure.     

An altered composition of the microbiome in microscopic colitis is driven towards the composition in healthy controls by treatment with budesonide

Background and aim: Microscopic colitis (MC) is an inflammatory disease of the bowel, hypothetically induced by an immunologic response to a luminal microbial agent. We aimed to characterize the microbiome composition in MC and subtypes collagenous colitis (CC) and lymphocytic colitis (LC) and to identify a possible microbial effect of treatment.

Method: Stool samples were collected from MC patients prior to treatment, at 8 weeks (during treatment) and at 16 weeks (after treatment), and from healthy controls, not receiving treatment, at matched time-points. Microbiome composition was analyzed by sequencing of the 16S and 18S genes. Differences between patients and controls were analyzed by Shannon’s diversity index (mean, standard deviation (SD)) and principal coordinate analysis (PCoA) complemented with a permanova test of UniFrac distances.

Results: Ten LC patients, 10?CC patients and 10 controls were included. By PCoA, the bacterial composition in MC patients differed from controls at baseline (p?=?.02), but not during and after treatment (p?=?.09 and p?=?.33, respectively). At baseline, bacterial diversity was lower in MC patients compared to controls (2.5, SD: 0.5 vs 3.5, SD: 0.3, p?<?.05). Diversity in MC patients increased during (3.0, SD: 0.6) and after treatment and (2.9, SD: 0.5) compared with baseline (p?<?.01). Eukaryotes were detected in fewer samples from MC patients compared with controls (11/20 (55%) vs. 9/10 (90%), p?=?.06) with no effect of treatment.

Conclusion: Microbiome composition is altered in MC patients. During and after treatment with budesonide the microbiome composition in MC patients was driven towards the composition in healthy controls.     

Correlation and concordance measures between clinical,endoscopic and histological scores activity in Crohn’s disease under treatment

Aim: Our aim was to evaluate the correlation and concordance measures between clinical, endoscopic and histologic remission in Crohn’s disease (CD) under treatment.

Method: Twenty-four patients with CD under treatment were included in a prospective consecutive cross-sectional study from January to September 2018. Clinical activity was assessed by Crohn’s Disease Activity Index (CDAI). All of the patients were submitted an ileocolonoscopy with biopsy and classified by Simple Endoscopic Score (SES-CD). Histologic activity was assessed by Global Histologic Activity Score (GHAS) modified. Remission was considered with CDAI <150; SES-CD ≤2 and GHAS ≤4.

Results: Clinical remission was established in 53%, however, only 50% had mucosal healing (MH) and 70% had inflammatory histologic activity. Correlation between endoscopic and histological measures was strong and positive (σ = 0.73, p?<?.0003). The concordance remission agreement between SES-CD and GHAS was weak with (κ) = 0.3 (IC 95%: ?0.09; 0.69). The greatest disparity arose when clinical activity (CDAI) was compared with histological measures (σ?=?0.20, p?=?.45), (κ)?=?0.26 (IC?=??0.03; 0.56).

Conclusion: The score SES-CD correlates well with histological score GHAS in CD under treatment, however, there is low concordance between both mainly in patients with anti-TNFs treatment. CDAI score had low correlation and concordance with histological score GHAS. In this sample, patients under treatment and without symptoms had low MH and histologic healing.     

Common themes and challenges in hemophilia care: a multinational perspective

Objective: To identify ways that provision of hemophilia care can be maximized at the local level, irrespective of available resources or cultural or geographic challenges.

Methods: The SHIELD group used its multinational experience to share examples of local initiatives that have been employed to deliver optimal hemophilia care.

Results: The examples were reviewed and categorized into four key themes: guidelines and algorithms for delivery of care; collaboration with patients and allied groups for care and education; registries for the monitoring of treatment and outcomes and health care planning and delivery; and opportunities for personalization of care. These themes were then incorporated into a road map for collaborative care in hemophilia that reflected the contribution of best practice.

Discussion: Differing healthcare reimbursement systems, budgetary constraints, and geographical and cultural factors make it difficult for any country to fully deliver ideal care for people with hemophilia. The SHIELD approach for collaborative care provides illustrative examples of how four key themes can be used to optimize hemophilia care in any setting.

Correlates of Mental Illness and Health Categories among Older Adults in China: An Empirical Study Based on the Two Continua Model

Objective: Keyes’ two continua model is a useful concept in which mental health and mental illness exist on two separate axes. Based on this model, this study examined the prevalence and correlates of three mental health categories among older adults in China.

Methods: Cross-sectional data were derived from Wave 1 of the Study on Global AGEing and Adult Health. Participants were categorized into complete mental health (CMH), complete mental illness (CMI), and moderate mental health (MMH) groups. Multinomial logistic regressions were used.

Results: The prevalence of CMH, CMI, and MMH in China was 18%, 16%, and 66%, respectively. Being female, unmarried, younger, and feeling unhealthy were more likely to result in placement in the CMI category. Employment, education, and cognitive function were identified as important protective factors of CMH. Age, income, urban or rural residence, and physical function difficulty were associated with all three categories.

Discussion: We demonstrated the utility of the two continua model in identifying mental health needs in Chinese contexts. The findings suggest that future policy reforms and clinical interventions should establish a more comprehensive mental health category as a screening tool nationwide. The promotion of social engagement could play an important role in treating mental illness and improving positive mental health.     

Poly-use of cannabis and other substances among juvenile-justice involved youth: variations in psychological and substance-related problems by typology

Background: Adolescent cannabis use is associated with increased risk for psychological problems, with evidence for more severe problems among youth who use cannabis in combination with other substances (i.e., polysubstance use). Juvenile offenders engage in both cannabis use and polysubstance use at higher rates than the general adolescent population. Yet, limited research has examined the relationship between cannabis poly-use (e.g., cannabis and alcohol use) and functional or psychological problems among juvenile offenders.

Objectives: The current study addresses this gap by examining the association of polysubstance use of cannabis compared to cannabis only use with cognitive functioning, psychological distress, and substance-related problems among juvenile detainees.

Methods: Participants were 238 detained youth ages 12–18 (80.4 % male, 77.3% non-White) who completed assessments of substance use, intellectual functioning, psychological symptoms, and substance-related problems. Youth were also assessed by a clinical psychologist for substance use disorder.

Results: Four cannabis-use typologies were identified; cannabis and alcohol use was the largest class, followed by cannabis only use, cannabis, alcohol and other drug use, then cannabis and other drug use. Polysubstance use was associated with lower scores on measures of intellectual functioning, more externalizing and internalizing symptomology, and more substance-related problems relative to cannabis only use. However, the relationship between polysubstance use and problems varied by typology.

Conclusions: Findings suggest that justice-involved youth engaged in polysubstance use may be at greater need for concurrent academic, affective, and behavioral support in their rehabilitation and transition back to the community.     

Complications and outcome of percutaneous endoscopic gastrostomy in a high-volume centre

Introduction: Percutaneous endoscopic gastrostomy (PEG) is the method of choice for long-term enteral feeding for patients with swallowing disorders and normal gut function. There is limited data regarding the demographics and clinical characteristics of patients from whom PEG was removed.

Patients and methods: We performed a retrospective analysis of all consecutive adult patients who underwent first placement of PEG between 1 August 2013 and 31 December 2015 at Karolinska University Hospital in Stockholm, Sweden.

Results: In total, 495 PEG were inserted in 495 patients during the study period, 56% male, mean age at insertion 67 years (range 19–95). Most patients belonged to the neurologic group (52%), followed by the oncologic (32%), another diagnosis (9%) and trauma (7%). Major complications occurred in 10 (2.0%) patients. There were no differences in the age or BMI of patients with either minor or major complications but both parameters were risk factors in terms of survival. PEG was removed from 165 (33.3%) patients, most of them from the oncology group, due to the improvement of general status of patients after specific oncologic treatment.

Conclusion: Increased age and low BMI were identified as risk factors for mortality but did not correspond with the rate of complications. Antibiotic prophylaxis with sulfamethoxazole and trimethoprim provides good protection for patients with PEG.     

Lipid membranes accelerate amyloid formation in the mouse model of AA amyloidosis

Introduction: AA amyloidosis develops as a result of prolonged inflammation and is characterized by deposits of N-terminal proteolytic fragments of the acute phase reactant serum amyloid A (SAA). Macrophages are usually found adjacent to amyloid, suggesting their involvement in the formation and/or degradation of the amyloid fibrils. Furthermore, accumulating evidence suggests that lipid membranes accelerate the fibrillation of different amyloid proteins.

Methods: Using an experimental mouse model of AA amyloidosis, we compared the amyloidogenic effect of liposomes and/or amyloid-enhancing factor (AEF). Inflammation was induced by subcutaneous injection of silver nitrate followed by intravenous injection of liposomes and/or AEF to accelerate amyloid formation.

Results: We showed that liposomes accelerate amyloid formation in inflamed mice, but the amyloidogenic effect of liposomes was weaker compared with AEF. Regardless of the induction method, amyloid deposits were mainly found in the marginal zones of the spleen and coincided with the depletion of marginal zone macrophages, while red pulp macrophages and metallophilic marginal zone macrophages proved insensitive to amyloid deposition.

Conclusions: We conclude that increased intracellular lipid content facilitates AA amyloid fibril formation and show that the mouse model of AA amyloidosis is a suitable system for further mechanistic studies.
