Published: July 2024

Abstract
Background
During epidemics, the number of individuals whose mental health is affected is greater than those affected by the infection itself. This is because psychological factors have a direct relationship with the primary causes of the disease and mortality worldwide. Therefore, an increasing investment in research and strategic actions for mental health is essential globally, given the prevalence of infectious diseases.
The aim of this study was to elucidate and describe the strategies for mental health preparedness and response during epidemics, with a focus on the COVID-19 pandemic in Iran.

Methods
A qualitative study was conducted in Iran from 2022 to 2023. Purposeful Sampling was employed, continuing until data saturation was achieved. Data collection involved semi-structured interviews and observational notes with 20 managers and experts possessing expertise, experience, and knowledge in mental health. Ultimately, the participants' opinions, based on their experiences, were analyzed using the qualitative content analysis method with a conventional approach, resulting in the categorization of data into codes, subcategories, and categories.

Results
The study revealed participants' opinions and experiences, categorized into two overarching categories: Preparedness, Policy-Making, and Planning Strategies (with four subcategories), and Response Strategies (comprising thirteen subcategories).

Conclusion
The opinions and experiences of managers and experts in this study revealed that an appropriate mental health response during pandemics requires preparedness before the occurrence of such crises and the implementation of suitable response strategies after the occurrence. Managers, policymakers, and decision-makers in this field should pay attention to the solutions derived from the experiences of such crises to respond more preparedly in the future.

Abstract
Purpose
The present study aimed to investigate the clinical characteristics and lung function impairment in young people diagnosed with chronic obstructive pulmonary disease (COPD).

Patients and methods
We retrospectively enrolled patients with COPD who underwent symptom assessment and comprehensive pulmonary function tests at the First Affiliated Hospital of Guangzhou Medical University between August 2017 and March 2022. The patients were categorized into two groups based on age: a young COPD group (aged 20–50 years) and an old COPD group (aged > 50 years).

Results
A total of 1282 patients with COPD were included in the study, with 76 young COPD patients and 1206 old COPD patients. Young COPD patients exhibited a higher likelihood of being asymptomatic, lower rates of smoking, and a lower smoking index compared to old COPD patients. Although young COPD patients had higher median post-bronchodilator forced expiratory volume in 1 s (post-BD FEV1) (1.4 vs.1.2 L, P = 0.019), diffusing capacity of the lung for carbon monoxide (DLCO) (7.2 vs. 4.6, P<0.001), and a lower median residual volume to total lung capacity ratio (RV/TLC) compared to their older counterparts, there were no differences observed in severity distribution by GOLD categories or the proportion of lung hyperinflation (RV/TLC%pred > 120%) between two groups. Surprisingly, the prevalence of reduced DLCO was found to be 71.1% in young COPD, although lower than in old COPD (85.2%).

Conclusion
Young COPD showed fewer respiratory symptoms, yet displayed a similar severity distribution by GOLD categories. Furthermore, a majority of them demonstrated lung hyperinflation and reduced DLCO. These results underscore the importance of a comprehensive assessment of lung function in young COPD patients.

Published: July 2024

Abstract
Background
Neoadjuvant chemotherapy (NAC) with radical cystectomy (RC) is the preferred first-line treatment for localized muscle-invasive bladder cancer (MIBC). In recent years, octogenarians have been undergoing RC uneventfully, but studies showed older adults receive NAC less often. We studied the utilization and effect of RC with or without NAC in octogenarians and compared survival outcomes between responders and non-responders.

Methods
In our retrospective study using the National Cancer Database (NCDB), we identified octogenarians with MIBC and urothelial histology who underwent RC with or without NAC between 2004 and 2018. The NAC cohort included patients who underwent RC with NAC, and the non-NAC cohort included those with or without adjuvant chemotherapy. The NAC cohort was subcategorized into responders and non-responders based on surgical pathology. Patients with comorbidity index > 1 were not included, thereby excluding patients with possible renal impairment. After propensity-matching, we compared the overall survival (OS) between NAC and non-NAC cohorts and responders and non-responders.

Results
33924 patients underwent RC, and 3056 octogenarians met our selection. Among them, 396 received NAC, and 2660 did not receive NAC. Among those who received NAC, 112(28.3%) experienced downstaging, and 223(56.4%) exhibited upstaging or no change (p < 0.001). After propensity-matching, the median OS of the NAC and non-NAC cohorts were 51.6 months and 31.3 months, respectively (p<0.001). Similarly, the median OS of responders and non-responders were 89.4 months and 26.5 months, respectively(p < 0.0001).

Conclusion
In our study, we observed that NAC with RC for MIBC may help to improve OS among healthy octogenarians. Similarly, responders had better OS than non-responders.

Abstract
Objectives
The objective of this study was to evaluate the effect of acidic beverages on the surface topography and elemental composition of human teeth.

Methods
A total of five highly acidic beverages (Red Bull, Pepsi, Apple Cidra, Tang Mosambi, and Tang Orange) were investigated. The tooth specimens of experimental groups were submerged in each beverage and incubated at 37 °C for 7 days, whereas, the tooth specimens of control groups were placed in distilled water. Afterwards, tooth specimens were analyzed using scanning electron microscopic (SEM), stereomicroscopic, and energy dispersive x-ray (EDX) techniques.

Results
All experimental groups revealed a decline in the tooth elements compared to controls, however, such decline was not statistically significant. Nevertheless, comparing the experimental groups, the Red Bull beverage caused a marked reduction in the percentage of both calcium and phosphorus elements compared to the Pepsi, Apple Cidra, Tang Mosambi, and Tang Orange beverages but it was insignificant as well in contrast to its control counterpart. All five acidic beverages demonstrated erosive potential under SEM analysis; however, each group of specimens showed a diverse amount of demineralization. In addition, all experimental groups exhibited significant discoloration of tooth specimens compared to their respective control counterparts.

Conclusions
Within the limitations of study, all five acidic beverages demonstrated erosive potential in the simulated in vitro conditions under SEM analysis; however, each group of specimens exhibited a different extent of demineralization. In addition, the overall effect of all beverages was insignificant under EDX analysis as no substantial difference was revealed between the elemental composition of experimental and control group specimens.

Published: July 2024

Abstract
Background
The scientific community has been particularly interested in oral squamous cell carcinoma (OSCC) because of the cancer’s extremely high incidence and fatality rates worldwide. It has been proposed that paxillin is involved in certain malignancies as an oncogene. Additionally, several investigations have assessed paxillin expression and investigated its function in developing distinct human carcinomas, including squamous cell carcinoma. Furthermore, it was discovered that there is a strong link between paxillin levels and cancer progression and spread.

Objective
This investigation was carried out to analyze and compare the salivary paxillin levels between oral potentially malignant disorders (OPMDs), OSCC and the healthy controls to assess its potential role as a biomarker of oral cancer aiming for early diagnosis and better prognosis of OSCC.

Methods
Forty-five patients, ranging in age from thirty to seventy-five, were divided into three groups: fifteen patients with OPMDs, fifteen patients with OSCC, and fifteen controls. Paxillin was identified in saliva samples by using an ELISA kit.

Results
Patients with OSCC and OPMDs have considerably greater salivary Paxillin levels than the healthy control group. The receiver operating curve (ROC) analysis was used in our study to distinguish patients with OPMDs from those with OSCC. The ROC curve constructed with the OPMDs group as the positives had lower sensitivity and area under the curve (AUC) values [100% and 1] than the ROC curve with the malignant group as the positives [93.3% and 0.997], respectively. Furthermore, ROC analysis performed between OPMDs group and the malignant group showed a specificity of 73.3% and a cut-off value ≥ 7.9 .

Conclusion
Paxillin can be considered a reliable biomarker for identifying and comparing OPMDs and OSCC cancerous changes.

Immediate risk of cervical intraepithelial neoplasia and diagnostic value of colposcopy among cytology-negative women with oncogenic HPV: a retrospective study
Authors: Dai Weichao , Wang Tongfei , Chen Lin , Qiu Zhongyuan , Chen Peifang , Chen Dezhao 
Published: July 2024

Abstract
Background
Cervical cancer screening results that are negative for cytology but positive for high-risk human papillomavirus (HR-HPV) are not uncommon. One-year follow-up is suggested for patients with no history of HPV positivity under the most recent American Society of Colposcopy and Cervical Pathology (ASCCP) guidelines (2019). The aim of this study was to evaluate the immediate risk of cervical intraepithelial neoplasia (CIN) among cytology-negative patients positive for HR-HPV. The diagnostic accuracy of colposcopy in these patients was investigated.

Methods
A retrospective study was conducted in patients who were cytology negative but HR-HPV positive and referred for colposcopy from January 2022 to August 2023. Patients were compared in terms of the immediate rate of CIN lesions among the HPV16-positive group, the HPV18-positive group and the non-16/18 HR-HPV-positive group. The distribution of CIN2 + lesions according to age was evaluated. The factors associated with the accuracy of colposcopy were evaluated using univariate and multivariate logistic regression.

Results
Among the 372 patients, 195 had chronic cervicitis, 131 had CIN1, 37 had CIN2/3, and nine had carcinoma. The immediate rates of CIN2 + lesions and CIN3 + lesions in patients who were not HR-HPV16/18-positive were comparable to those in patients who were HPV16/18-positive (P = 0.699). In addition, among patients diagnosed with CIN2 + lesions, 8 (17.39%) patients were women aged < 30 years. When pathological results were used as a reference, the consistency rate of colposcopy was 61.0% (227/372). Multivariate analyses revealed that age and the type of cervical transformation zone were independent factors affecting the accuracy of colposcopy (P < 0.001).

Conclusions
In countries with limited resources, immediate colposcopy referral should be recommended for patients who are cytology negative but HR-HPV-positive (including non-16/18 HR-HPV-positive), and cervical cancer screening via cotesting should be suggested for women aged < 30 years. Colposcopy has moderate diagnostic value and can be affected by age and the type of cervical transformation zone.
Influence of a rural Longitudinal Integrated Clerkship on medical graduates’ geographic and specialty decisions: a constructivist grounded theory study
Authors: Beattie Jessica , Binder Marley , Beks Hannah , Fuller Lara 
Published: July 2024

Abstract
Background
Like many countries, Australia is suffering from a longstanding and persistent medical workforce maldistribution with fewer doctors per capita in rural locations and a trend towards sub-specialisation. Longitudinal Integrated Clerkships (LIC), a medical education model, are more likely than other clerkship models to produce graduates who work rurally, in communities of increasing remoteness and in primary care. While this quantitative data is essential, there has been a dearth of program-specific evidence explaining this phenomenon.

Methods
To address this knowledge gap, a constructivist qualitative grounded theory approach was employed to identify how the Deakin University comprehensive rural LIC influences graduates’ (2011–2020) career decisions in terms of both medical specialty and geographic practice location.

Results
Thirty-nine graduates participated in qualitative interviews. The Rural LIC Career Decision Making Framework was developed, postulating that an alignment of personal and program factors under the central concept of ‘choosing to participate’ can influence graduates’ geographic and specialist career decisions, both individually and symbiotically. Once embedded in the clerkship, participation was augmented by the concepts of learning design affordance and learning in place, providing the participants with longitudinal opportunities to experience and compare medical disciplines in an integrated manner.

Conclusions
The developed framework presents contextual elements of the program that were deemed influential on graduates’ subsequent career decisions. The alignment of these elements with the program’s mission statement has the capacity to enhance the program’s rural workforce goals. Regardless of graduates’ willingness to participate in the program, a transformation occurred. Transformation occurs through reflection, either challenging or confirming the graduate’s pre-conceived ideas about career decisions and in turn influencing professional identity formation.

Abstract
Aims
European registries and retrospective cohort studies have highlighted the failure to achieve low-density lipoprotein-cholesterol (LDL-C) targets in many very high-risk patients. Hospitalized patients are often frail, and frailty is associated with all-cause and cardiovascular mortality. The aim of this study is to evaluate LDL-C levels in a real-world inpatient setting, identifying cardiovascular risk categories and highlighting treatment gaps in the implementation of LDL-C management.

Methods
This retrospective, observational study included all adult patients admitted to an Italian hospital between 2021 and 2022 with available LDL-C values during hospitalization. Disease-related real-world data were collected from Hospital Information System using automated data extraction strategies and through the implementation of a patient-centered data repository (the Dyslipidemia Data Mart). We performed assessment of cardiovascular risk profiles, LDL-C target achievement according to the 2019 ESC/EAS guidelines, and use of lipid-lowering therapies (LLT).

Results
13,834 patients were included: 17.15%, 13.72%, 16.82% and 49.76% were low (L), moderate (M), high (H) and very high-risk (VH) patients, respectively. The percentage of on-target patients was progressively lower towards the worst categories (78.79% in L, 58.38% in M, 33.3% in H and 21.37% in VH). Among LLT treated patients, 28.48% were on-target in VH category, 47.60% in H, 69.12% in M and 68.47% in L. We also analyzed the impact of monotherapies and combination therapies on target achievement.

Conclusions
We found relevant gaps in LDL-C management in the population of inpatients, especially in the VH category. Future efforts should be aimed at reducing cardiovascular risk in these subjects.

Published: July 2024

Abstract
Background
The COVID-19 pandemic has posed significant challenges to nations worldwide, affecting various sectors of society. Women’s HIV harm reduction centers, which provide critical services, have also been affected by these difficulties. This study aimed to examine the challenges of the COVID-19 pandemic on the services offered by women’s HIV harm reduction centers from the perspective of clients.

Methods
A convergent mixed-method design was utilized to gain in-depth insights into the challenges of COVID-19 on the services provided by women’s HIV harm reduction centers, counseling centers, and night shelters that cater to women at risk, such as drug users, sex workers, and the homeless population, in three provinces (Tehran, Khuzestan, and Kermanshah) in Iran. The study was conducted from January to May 2023. The quantitative aspect of the study employed a cross-sectional method with a sample size of 430 individuals. A researcher-developed questionnaire was used to assess a range of services. The qualitative part of the study involved traditional content analysis and included 32 individual interviews. The integration of qualitative and quantitative results was performed during the interpretation phase to provide a comprehensive understanding of the challenges of COVID-19 on women’s HIV harm reduction centers.

Results
In the quantitative phase, the mean age of women was 39.0 ± 10.2 years. 165 women reported a history of COVID-19, which accounts for 38.4% of the total. More than half of them (n = 102, 61.8%) recovering at home. The majority of women (n = 365, 84.9%) mentioned receiving the COVID-19 vaccine. COVID-19 diagnostic tests were conducted for 74.2% (n = 319) of women. Women expressed higher satisfaction with the services (HIV prevention services, and accommodation services) before the COVID-19 pandemic compared to the satisfaction during the pandemic. The qualitative analysis identified emerging challenges related to the COVID-19 pandemic in two categories: personal challenges and mismanagement of services, comprising nineteen subcategories.

Conclusion
The findings of this study highlight the adverse impact of the COVID-19 pandemic on the services provided by women’s HIV harm reduction centers, in contrast to the pre-pandemic period. To mitigate these negative effects, it is crucial to implement preventive measures and practical solutions. This may involve addressing the personal and management challenges of the centers.

Published: July 2024

Abstract
Objective
Recent studies have indicated that HOTTIP and MEG3 are associated with the initiation and progression of various types of tumors, including nasopharyngeal carcinoma (NPC). This investigation aimed to elucidate the impact of HOTTIP and MEG3 polymorphisms on the susceptibility and clinicopathologic characteristics of NPC.

Methods
This research employed next-generation sequencing and multiplex PCR to assess the polymorphisms of HOTTIP rs1859168 and MEG3 rs7158663 in 200 NPC and 200 healthy individuals respectively. HOTTIP and MEG3 expression were assessed via qRT-PCR assessment. Furthermore, the genotypes and alleles frequency of rs1859168 and rs7158663 were compared between healthy and NPC individuals to elucidate their influence on NPC susceptibility and relation with clinicopathologic characteristics.

Results
In comparison with the healthy cohort, the presence of HOTTIP rs1859168 CC genotype and the C allele were markedly linked with increased NPC incidence (p < 0.05). Furthermore, the MEG3 rs7158663 AA genotype and the A allele also indicated an increased risk of NPC (p < 0.05). The subgroup analysis of age, EBV infection, gender, nationality, smoking, and drinking status revealed no marked association between rs1859168 and rs7158663 genotypes and these potential confounding factors. Moreover, it was observed that rs1859168 CC and rs7158663 AA genotypes were related to local tumor invasion and lymph node metastasis. Additionally, HOTTIP indicated a marked elevation, while MEG3 substantially reduced in NPC samples than the normal nasopharyngeal biospecimens. Patients who carried CC or CA genotypes rather than the HOTTIP rs1859168 AA genotype, had substantially higher HOTTIP levels, while patients with rs7158663 AA or GA genotypes indicated notably lower expression of MEG3 than GG genotype carriers.

Conclusion
Individuals with genetic variants of HOTTIP rs1859168 and MEG3 rs7158663 might have an increased risk of NPC susceptibility and related clinicopathologic characteristics, potentially by affecting the expression of HOTTIP and MEG3.
