Published: November 2022

Abstract
Background
Anal human papillomavirus (HPV) disproportionately affects men who have sex with men (MSM), particularly those who are older and those living with HIV. After experiencing difficulty recruiting older MSM into a study on aging and anal HPV, we conducted a sub-study to gain feedback on our recruitment methods and explore barriers and facilitators to participating in anal HPV research.

Methods
We conducted focus groups with 30 men who have sex with men (MSM), both HIV-negative and MSM living with HIV, ages 50–75.

Results
We identified multiple themes that were barriers to participation including: (1) lack of knowledge about human papillomavirus and anal cancer; (2) research focused on anal cancer or discomfort with topics or procedures concerning the anus; (3) stigma including stigma associated with being men who have sex with men, being out, being a receptive partner, and being considered “older” in the gay community; and (4) confidentiality concerns including a fear of breach of confidentiality. Facilitators to participation were also identified; these motivational factors include altruism, wanting recommendations from a doctor, and desire to receive the best available care.

Conclusion
Researchers seeking to enroll older men who have sex with men should be aware of these barriers and facilitators to participation in order to maximize recruitment.
Cultural adaptation of the savvy caregiver program for Korean Americans with limited English proficiency: a feasibility and acceptability study

Published: November 2022

Abstract
Background
Limited English proficiency (LEP) of dementia caregivers poses a critical barrier to these caregivers’ access to evidence-based interventions. In an effort to make such interventions available and accessible to dementia caregivers with LEP, in the present study we use Barrera and colleagues’ (2011) three-step model of cultural adaptation: (1) information gathering, (2) preliminary adaptation, and (3) full adaptation. Selecting Korean Americans as a target group and the Savvy Caregiver Program (SCP) as a target intervention, we demonstrate the sequential process of cultural adaption and report the outcomes on feasibility and acceptability.

Methods
Preliminary adaptation with linguistic attunement was conducted by translating the SCP manual into Korean and certifying two lay individuals who were bilingual in English and Korean as Savvy trainers. The 6-week online SCP program was delivered by the two trainers in Korean with six to seven caregiver participants per trainer (N = 13). Feasibility and acceptability of the SCP for both caregiver participants and trainers were assessed using mixed methods, and their data then informed full adaptation.

Results
Findings not only showed the initial efficacy of the linguistically attuned SCP but also suggested areas for further modification. Data-driven assessment yielded a list of recommended changes for full adaptation, which was reviewed by the SCP developer to ensure fidelity and by community and research partners to confirm contextual and cultural relevance.

Conclusions
The adopted changes are broadly summarized as representing logistical, technical, and cultural issues. Given our refined set of educational materials and implementation guidelines, we discuss future directions for research and development.

Published: November 2022

Abstract
Background
Due to the nutritive and immunologic benefits of breastmilk, children should be exclusively breastfed for the first 6 months of life, even during the corona virus pandemic. However, fear of transmission risk and pandemic-related restrictions could undermine the practice of breastfeeding. This study aimed to assess the knowledge, attitude, and determinants of exclusive breastfeeding (EBF) during COVID-19 among lactating mothers in Mekelle, Tigrai, Ethiopia.

Methods
A community based cross-sectional study was conducted among 621 lactating mothers living in Mekelle city, Tigrai, from April to June, 2021. Data were collected using an adapted form of a standard KAP questionnaire. Binary logistic regression was used to determine the independent determinants of EBF at a statistical significance of p < 0.05. The strength of the association was measured by odds ratio and 95% confidence interval.

Results
Four hundred (64.4%) mothers exclusively breastfed their children. Infants from female-headed households had twice (AOR 2.21; 95% CI 1.31, 3.71) higher odds of EBF. Higher educational status was associated with higher odds of EBF practice. A unit increase in parity was associated with a 23% increase in the odds of EBF. Mothers who received breastfeeding information had a 73% (AOR 1.73; 95% CI 1.17, 2.56) higher odds of EBF. Moreover, mothers with high knowledge score and positive attitude showed a 74% higher (AOR 1.74; 95% CI 1.20, 2.51) and more than double (AOR 2.35; 95% CI 1.50, 3.70) odds of EBF, respectively.

Conclusion
About two-thirds of the mothers practiced EBF. Household head, maternal educational, parity, breastfeeding information, knowledge of breastfeeding, and attitude towards EBF were significant determinants of EBF. Our study findings highlighted that programs that enhance women’s participation in education and decision-making could improve EBF practice. Besides, during the COVID-19 pandemic, providing lactating mothers with adequate and up-to-date breastfeeding information could be significant in improving EBF practice.

Abstract
Background
Induction or adjuvant therapies are not always beneficial for thoracic esophageal squamous cell carcinoma (ESCC) patients, and it is thus important to identify patients at high risk for postoperative ESCC recurrence. We investigated the usefulness of the total metabolic tumor volume (TMTV) for predicting the postoperative recurrence of thoracic ESCC.

Methods
We retrospectively analyzed the cases of 163 thoracic ESCC patients (135 men, 28 women; median age of 66 [range 34–82] years) treated at our hospital in 2007–2012. The TMTV was calculated from the fluorine-18 fluorodeoxyglucose (18F-FDG) uptake in the primary lesion and lymph node metastases. The optimal cut-off values for relapse and non-relapse were obtained by the time-dependent receiver operating curve analyses. Relapse-free survival (RFS) was evaluated by the Kaplan-Meier method, and between-subgroup differences in survival were analyzed by log-rank test. The prognostic significance of metabolic parameters and clinicopathological variables was assessed by a Cox proportional hazard regression analysis. The difference in the failure patterns after surgical resection was evaluated using the χ2-test.

Results
The optimal cut-off value of TMTV for discriminating relapse from non-relapse was 3.82. The patients with a TMTV ≥3.82 showed significantly worse prognoses than those with low values (p < 0.001). The TMTV was significantly related to RFS (model 1 for preoperative risk factors: TMTV: hazard ratio [HR] =2.574, p = 0.004; model 2 for preoperative and postoperative risk factors: HR = 1.989, p = 0.044). The combination of the TMTV and cN0–1 or pN0–1 stage significantly stratified the patients into low-and high-risk recurrence groups (TMTV cN0–1, p < 0.001; TMTV pN0–1, p = 0.004). The rates of hematogenous and regional lymph node metastasis were significantly higher in the patients with TMTV ≥3.82 than those with low values (hematogenous metastasis, p < 0.001, regional lymph node metastasis, p = 0.011).

Conclusions
The TMTV was a more significantly independent prognostic factor for RFS than any other PET parameter in patients with resectable thoracic ESCC. The TMTV may be useful for the identifying thoracic ESCC patients at high risk for postoperative recurrence and for deciding the patient management.

Published: November 2022

Abstract
Background
The aim of this study is to explore the expression and clinical relevance of CAF-associated markers, EZH2 and FOXM1 in gastric samples.

Methods
Protein expression were detected and evaluated by multi-plex immunofluorescence (mIF) in 93 cases of gastric cancer (GC) and 31 cases of gastric intraepithelial neoplasia (GIN). The correlation among their expression, and the relationship of them with clinicopathological parameters and prognosis in GC were then analyzed.

Results
FAP was specific expressed in the CAFs of GC samples, and thus be utilized as a CAF-associated marker in our subsequently analysis. The immunostaining of EZH2, FOXM1 and FAP were significantly upregulated in patients with GC tissues than in those normal gastric mucosa or GIN tissues. The average fluorescence intensity of FAP was slightly positively correlated with EZH2 in GC, GIN and normal samples, whereas the percentage of FAP positive cells has no correlation with that of EZH2. Both the percentage of positive cells and the average fluorescence intensity of FOXM1 were positively correlated with that of FAP and EZH2 in GC, GIN and normal samples, except for FOXM1 and EZH2 expression in normal tissue samples. No significant association was observed between FAP expression and any clinicopathological parameters, whereas the positive frequency of EZH2 and FOXM1 were correlated with tumor location significantly and tumor invasion depth, respectively. In addition, there was strong positive correlations between FAP protein expression and overall survival (OS) and disease-free survival (DFS), and EZH2 expression was positively associated with OS in patients with GC. Furthermore, EZH2 and FAP protein expression was an independent prognostic factor for OS and DFS, respectively.

Conclusions
These results suggest that both EZH2 and FOXM1 expression was positively associated with CAFs abundance in GC. They may be potential cellular target for therapeutic intervention, especially in patients with a large number of CAFs.
Prescreening of tumor samples for tumor-centric transcriptome analyses of lung adenocarcinoma
Authors: Kim Nayoung , Jeong Dasom , Jo Areum , Eum Hye Hyeon , Lee Hae-Ock 
Published: November 2022

Abstract
Background
Single-cell RNA sequencing (scRNA-seq) enables the systemic assessment of intratumoral heterogeneity within tumor cell populations and in diverse stromal cells of the tumor microenvironment. Gain of treatment resistance during tumor progression or drug treatment are important subjects of tumor-centric scRNA-seq analyses, which are hampered by scarce tumor cell portions. To guarantee the inclusion of tumor cells in the data analysis, we developed a prescreening strategy for lung adenocarcinoma.

Methods
We obtained candidate genes that were differentially expressed between normal and tumor cells, excluding stromal cells, from the scRNA-seq data. Tumor cell-specific expression of the candidate genes was assessed via real-time reverse transcription-polymerase chain reaction (RT-PCR) using lung cancer cell lines, normal vs. lung cancer tissues, and lymph node biopsy samples with or without metastasis.

Results
We found that CEA cell adhesion molecule 5 (CEACAM5) and high mobility group box 3 (HMGB3) were reliable markers for RT-PCR-based prescreening of tumor cells in lung adenocarcinoma.

Conclusions
The prescreening strategy using CEACAM5 and HMGB3 expression facilitates tumor-centric scRNA-seq analyses of lung adenocarcinoma.

Abstract
Background
Autoimmune blistering skin diseases (AIBD) are a group of rare chronic autoimmune diseases which are associated with ocular surface diseases especially dry eye disease. This study is designed to investigate the relationship between ocular surface disorders and quality of life among patients with autoimmune blistering skin diseases.

Methods
Twenty-four AIBD patients (18 pemphigus and 7 pemphigoid) and twenty-five non-AIBD controls were included. Ocular surface disease index (OSDI), ocular surface evaluation, including slit-lamp examination, Schirmer I test, tear break-up time, corneal fluorescein staining, lid-parallel conjunctival folds, meibomian gland evaluation, presence of symblepharon and corneal opacity were assessed. Life quality was evaluated by multiple questionnaires, including Medical Outcomes Study 36-Item Short Form Questionnaire (SF-36), Hospital Anxiety and Depression Scale (HADS), Pittsburgh Sleep Quality Index (PSQI) and Health Assessment Questionnaire-Disability Index (HAQ-DI). Ocular surface tests and quality of life were compared between AIBD patients and non-AIBD controls. In the AIBD patients, the associations between ocular surface parameters and quality of life were also evaluated.

Results
92% of AIBD patients and 87.5% of age- and sex-matched non-AIBD controls were diagnosed with dry eye in this study. Compared with non-AIBD controls, AIBD patients reported lower SF-36 scores (P < 0.05) and severer OSDI, Schirmer I test, tear break-up time, corneal fluorescein staining, presence of symblepharon and corneal opacity measures (P < 0.05). OSDI, Schirmer I test were correlated with SF-36 composite scores or scores on the SF-36 subscales.

Conclusions
AIBD patients experience reduced quality of life and more severe ocular surface disorders including dry eye, symblepharon and corneal opacity. Early treatments of dry eye and collaborations among multidisciplinary physicians are necessary in patients with AIBD.

Published: November 2022

Abstract
Background
This study aims to explore the association between dietary acid load and hyperuricemia in Chinese adults.

Methods
A case-control study was conducted. Adult participants with hyperuricemia were recruited as the cases and those without hyperuricemia were as the controls. Food consumption was evaluated by food frequency questionnaire (FFQ). Dietary acid load was assessed by potential renal acid load (PRAL) and net endogenous acid production (NEAP). Dietary acid load was divided into four levels: the first quartile (Q1), the second quartile (Q2), the third quartile (Q3) and the fourth quartile (Q4). Logistic regression model was applied for exploring the association between dietary acid load (PRAL and NEAP) and hyperuricemia. Odds ratio (OR) and its correspondence confidence interval (CI) were computed.

Results
A total of 290 participants were eligible in this study, in which there were 143 individuals in case group and 147 in control group. A higher level of PRAL was found to be associated with odds of hyperuricemia. ORs of hyperuricemia for Q2, Q3 and Q4 of PRAL were 2.74 (95%CI: 1.94 ~ 3.88, p-value: 0.004), 2.90 (95%CI: 2.05 ~ 4.10, p-value: 0.002) and 3.14 (95%CI: 2.22 ~ 4.45, p-value: 0.001), respectively. There was a positive association between elevated NEAP and hyperuricemia. OR of hyperuricemia for Q2 was not material significance (OR:1.54, 95%CI: 0.93 ~ 2.53, p-value: 0.210), however, ORs of hyperuricemia for Q3 (OR: 2.40, 95%CI: 1.70 ~ 3.38, p-value: 0.011) and Q4 (OR: 3.27, 95%CI: 2.31 ~ 4.62, p-value: 0.001) were statistically significant.

Conclusion
Higher level of dietary acid load was found to be associated with hyperuricemia in Chinese adults, indicative of advocation of a well-balanced diet in this population.
Women with lipoedema: a national survey on their health, health-related quality of life, and sense of coherence
Authors: Falck Johanna , Rolander Bo , Nygårdh Annette , Jonasson Lise-Lotte , Mårtensson Jan 
Published: November 2022

Abstract
Background
Lipoedema is a chronic disease in adipose tissue that almost exclusively affects women during periods of hormonal alterations. Its main symptoms include an abnormal accumulation of subcutaneous fat in the buttock, hips, and legs, which is associated with pain, swelling, and easy bruising. Herein, a grading in three stages is used to determine disease progression. Problematically, lipoedema manifestations are often confused with lifestyle-induced obesity, which is why the various health problems among affected women often remain unrecognized. Overall, research on lipoedema is scarce. As such, this study examined the health, health-related quality of life (HRQOL), and sense of coherence (SOC) among women with lipoedema.

Methods
We conducted a national cross-sectional study using an online survey assessing sociodemographic data, lipoedema characteristics, symptom severity, comorbidities, HRQOL (RAND-36), and SOC (SOC-13). In total, 245 women with lipoedema, recruited from all Lipoedema Association groups in Sweden, participated. Data were compiled with descriptive statistics, and mean differences between groups were analysed by using parametric and non-parametric tests.

Results
Moderate and severe leg heaviness, pain, numbness, cold skin, feeling cold, easy bruising, and sleep problems were found to occur in all lipoedema stages. Moreover, almost all participants reported having comorbidities. Worse physical health and most substantial limitations in daily life were reported among women with the most progressive lipoedema (i.e., stage 3). Social and emotional functioning and SOC were found to be, on the other hand, primarily related to respondents’ sociodemographic data and their ages at lipoedema onset. Even though approximately 70% of the women had experienced lipoedema onset before age 30, only three (1.6%) had been diagnosed by a healthcare professional before that age.

Conclusion
Having lipoedema is associated with several health problems and a lower HRQOL. In addition, the extent of delay in diagnosis within this sample indicates that many women with lipoedema are often underdiagnosed and are left without support from healthcare. These findings call for the need for greater attention on lipoedema. Moreover, further studies on how women with lipoedema manage their health and symptoms, as well as on their experiences of healthcare services and lipoedema treatments, are needed.
Antioxidant and anti-inflammatory activities of Centratherum anthelminticum (L.) Kuntze seed oil in diabetic nephropathy via modulation of Nrf-2/HO-1 and NF-κB pathway
Authors: Baig Nida , Sultan Rabia , Qureshi Shamim Akhtar 
Published: November 2022

Abstract
Background
Type 2 diabetes mellitus (T2DM) approximately constitutes 90% of the reported cases. 30-40% of diabetics eventually develop diabetic nephropathy (DN); accounting for one of the major causes of morbidity and mortality. Increased glucose autoxidation and non-enzymatic glycation of proteins in diabetic kidneys lead to the excessive generation of reactive oxygen species (ROS) that results in lipid peroxidation and activation of inflammatory mediators which overwhelms the scavenging capacity of the antioxidant defense system (Nrf2/Keap1/HO-1). Centratherum anthelminticum commonly called as kali zeeri (bitter cumin) and its seeds are well known for culinary purposes in Asia (Pakistan). It has reported anti-inflammatory, antioxidant, and anti-diabetic activities. The present study has attempted to explore the in-vivo anti-inflammatory, antioxidant and antihyperglycemic potential of the C. anthelminticum seed’s fixed oil (FO) and its fractions in high fat-high fructose-streptozotocin (HF-HFr-STZ) induced T2DM rat model.

Methods
The T2DM rat model was developed by giving a high-fat and high-fructose diet followed by a single intraperitoneal injection of streptozotocin (STZ 60 mg/kg) on 28th day of the trial. After 72 hours of this injection, rats showing fasting blood glucose (FBG) levels≥230 mg/dL were recruited into six groups. These groups were orally administered distilled water (1 mL/kg), Gliclazide (200 mg/kg), Centratherum anthelminticum seed (FO) and its hexane (HF), chloroform (CF) and ethanol (EF) soluble fractions (200 mg/kg each), respectively for 4 weeks (i.e. 28 days). Blood, serum, and kidney tissue samples of euthanized animals were used for biochemical, pro-inflammatory, and antioxidant markers (ELISA, qRT-PCR, and spectrophotometric assays) and histology, respectively.

Results
C. anthelminticum FO and its fractions reduced the lipid peroxidation, and improved the antioxidant parameters: enzymatic (SOD, CAT, and GPx), non-enzymatic (GSH), and mRNA expression of anti-inflammatory markers (Nrf-2, keap1, and HO-1). mRNA expression of inflammatory and apoptotic markers (TNF-α, IL-1β, COX-1, NF-κB, Bax, and Bcl-2) were attenuated along with improved kidney architecture.

Conclusion
C. anthelminticum can mitigate inflammation and oxidative stress in early DN. The anti-nephropathic effect can be attributed to its ability to down-regulate NF-κB and by bringing the Nrf-2 expression levels to near normal.
