Abstract
Background
Older adults are increasingly susceptible to prolonged illness, multiple chronic diseases, and disabilities, which can lead to the coexistence of multimorbidity and frailty. Multimorbidity may result in various noncommunicable disease (NCD) patterns or configurations that could be associated with frailty and death. Mortality risk may vary depending on the presence of specific chronic diseases configurations or frailty.

Methods
The aim was to examine the impact of NCD configurations on mortality risk among older adults with distinct frailty phenotypes. The population was analyzed from the Costa Rican Longevity and Healthy Aging Study Cohort (CRELES). A total of 2,662 adults aged 60 or older were included and followed for 5 years. Exploratory factor analysis and various clustering techniques were utilized to identify NCD configurations. The frequency of NCD accumulation was also assessed for a multimorbidity definition. Frailty phenotypes were set according to Fried et al. criteria. Kaplan‒Meier survival analyses, mortality rates, and Cox proportional hazards models were estimated.

Results
Four different types of patterns were identified: ‘Neuro-psychiatric’, ‘Metabolic’, ‘Cardiovascular’, and ‘Mixt’ configurations. These configurations showed a higher mortality risk than the mere accumulation of NCDs [Cardiovascular HR:1.65 (1.07–2.57); ‘Mixt’ HR:1.49 (1.00-2.22); ≥3 NCDs HR:1.31 (1.09–1.58)]. Frailty exhibited a high and constant mortality risk, irrespective of the presence of any NCD configuration or multimorbidity definition. However, HRs decreased and lost statistical significance when phenotypes were considered in the Cox models [frailty + ‘Cardiovascular’ HR:1.56 (1.00-2.42); frailty + ‘Mixt’:1.42 (0.95–2.11); and frailty + ≥ 3 NCDs HR:1.23 (1.02–1.49)].

Conclusions
Frailty accompanying multimorbidity emerges as a more crucial indicator of mortality risk than multimorbidity alone. Therefore, studying NCD configurations is worthwhile as they may offer improved risk profiles for mortality as alternatives to straightforward counts.

Abstract
Background
Mental health (MH) is extremely relevant when referring to people living with a chronic disease, such as people living with HIV (PLWH). In fact – although life expectancy and quality have increased since the advent of antiretroviral therapy (ART) – PLWH carry a high incidence of mental disorders, and this burden has been exacerbated during the COVID-19 pandemic. In this scenario, UNAIDS has set new objectives for 2025, such as the linkage of at least 90% of PLWH to people-centered, context-specific MH services. Aim of this study was to determine the prevalence of MD in PLWH followed at the Clinic of Infectious Diseases of the University of Bari, Italy.

Methods
From January 10th to September 10th, 2022, all PLWH patients accessing our outpatient clinic were offered the following standardized tools: HAM-A for anxiety, BDI-II for depression, PC-PTSD-5 for post-traumatic stress disorder, CAGE-AID for alcohol-drug abuse. Factors associated with testing positive to the four MD were explored with a multivariable logistic regression model.

Results
578 out of 1110 HIV-patients agreed to receive MH screening, with 141 (24.4%) people resulting positive to at least one MH disorder. HAM-A was positive in 15.8% (n = 91), BDI-II in 18% (n = 104), PC-PTSD-5 in 5% (n = 29) and CAGE in 6.1% (n = 35). The multivariable logistic regression showed a higher probability of being diagnosed with anxiety, depression and post-traumatic stress disorder for PLWH who reported severe stigma, social isolation, psychological deterioration during the COVID-19 pandemic and for those receiving a dolutegravir (DTG)-based regimen. Moreover, history of drug use (OR 1.13; [95% CE 1.06–4.35]), family stigma (2.42 [1.65–3.94]) and social isolation (2.72 [1.55;4.84]) were found to be associated to higher risk for substance use disorder.

Conclusions
In this study, stigma was a strong predictor for being diagnosed of a MH disorder among PLWH. Also, the possible role of dolutegravir as a risk factor for the onset of MH disorders should be considered in clinical practice, and MH of patients receiving DTG-containing regimens should be constantly monitored.

AbstractCat scratch disease (CSD) is caused by Bartonella henselae (B. henselae) and presents as lymphadenopathy following close contact with cats. However, in context of the global COVID-19 pandemic, clinical manifestations of CSD may vary, posing new challenges for healthcare professionals. Here we describe a case of a 54-year-old male with painful left upper arm mass, which gradually resolved until he was infected with COVID-19. The mass then rapidly progressed before admission. Meanwhile, pulmonary symptoms including pleural effusion emerged simultaneously. The cause was undetermined with routine blood culture and pathological test until the next generation sequencing (NGS) confirmed the presence of B. henselae. We believe this case is the first to report localized aggravation of CSD after COVID-19 infection and hopefully, offers treatment experience for clinicians worldwide.
Contrast-induced acute kidney injury: a review of definition, pathogenesis, risk factors, prevention and treatment
Authors: Li Yanyan , Wang Junda 
Published: April 2024

AbstractContrast-induced acute kidney injury (CI-AKI) has become the third leading cause of hospital-acquired AKI, which seriously threatens the health of patients. To date, the precise pathogenesis of CI-AKI has remained not clear and may be related to the direct cytotoxicity, hypoxia and ischemia of medulla, and oxidative stress caused by iodine contrast medium, which have diverse physicochemical properties, including cytotoxicity, permeability and viscosity. The latest research shows that microRNAs (miRNAs) are also involved in apoptosis, pyroptosis, and autophagy which caused by iodine contrast medium (ICM), which may be implicated in the pathogenesis of CI-AKI. Unfortunately, effective therapy of CI-AKI is very limited at present. Therefore, effective prevention of CI-AKI is of great significance, and several preventive options, including hydration, antagonistic vasoconstriction, and antioxidant drugs, have been developed. Here, we review current knowledge about the features of iodine contrast medium, the definition, pathogenesis, molecular mechanism, risk factors, prevention and treatment of CI-AKI.

Published: April 2024

Abstract
Background
Maternal overweight/obesity and excessive gestational weight gain (GWG) are frequently reported to be risk factors for obesity and other metabolic disorders in offspring. Cord blood metabolites provide information on fetal nutritional and metabolic health and could provide an early window of detection of potential health issues among newborns. The aim of the study was to explore the impact of maternal prepregnancy overweight/obesity and excessive GWG on cord blood metabolic profiles.

Methods
A case control study including 33 pairs of mothers with prepregnancy overweight/obesity and their neonates, 30 pairs of mothers with excessive GWG and their neonates, and 32 control mother-neonate pairs. Untargeted metabolomic profiling of umbilical cord blood samples were performed using UHPLC‒MS/MS.

Results
Forty-six metabolites exhibited a significant increase and 60 metabolites exhibited a significant reduction in umbilical cord blood from overweight and obese mothers compared with mothers with normal body weight. Steroid hormone biosynthesis and neuroactive ligand‒receptor interactions were the two top-ranking pathways enriched with these metabolites (P = 0.01 and 0.03, respectively). Compared with mothers with normal GWG, in mothers with excessive GWG, the levels of 63 metabolites were increased and those of 46 metabolites were decreased in umbilical cord blood. Biosynthesis of unsaturated fatty acids was the most altered pathway enriched with these metabolites (P < 0.01).

Conclusions
Prepregnancy overweight and obesity affected the fetal steroid hormone biosynthesis pathway, while excessive GWG affected fetal fatty acid metabolism. This emphasizes the importance of preconception weight loss and maintaining an appropriate GWG, which are beneficial for the long-term metabolic health of offspring.

Published: April 2024

Abstract
Background
Leptomeningeal metastasis (LM) of small cell lung cancer (SCLC) is a highly detrimental occurrence associated with severe neurological disorders, lacking effective treatment currently. Proteolysis-targeting chimeric molecules (PROTACs) may provide new therapeutic avenues for treatment of podophyllotoxin derivatives-resistant SCLC with LM, warranting further exploration.

Methods
The SCLC cell line H128 expressing luciferase were mutated by MNNG to generate H128-Mut cell line. After subcutaneous inoculation of H128-Mut into nude mice, H128-LM and H128-BPM (brain parenchymal metastasis) cell lines were primarily cultured from LM and BPM tissues individually, and employed to in vitro drug testing. The SCLC-LM mouse model was established by inoculating H128-LM into nude mice via carotid artery and subjected to in vivo drug testing. RNA-seq and immunoblotting were conducted to uncover the molecular targets for LM.

Results
The SCLC-LM mouse model was successfully established, confirmed by in vivo live imaging and histological examination. The upregulated genes included EZH2, SLC44A4, VEGFA, etc. in both BPM and LM cells, while SLC44A4 was particularly upregulated in LM cells. When combined with PROTAC EZH2 degrader-1, the drug sensitivity of cisplatin, etoposide (VP16), and teniposide (VM26) for H128-LM was significantly increased in vitro. The in vivo drug trials with SCLC-LM mouse model demonstrated that PROTAC EZH2 degrader-1 plus VM26 or cisplatin/ VP16 inhibited H128-LM tumour significantly compared to VM26 or cisplatin/ VP16 alone (P < 0.01).

Conclusion
The SCLC-LM model effectively simulates the pathophysiological process of SCLC metastasis to the leptomeninges. PROTAC EZH2 degrader-1 overcomes chemoresistance in SCLC, suggesting its potential therapeutic value for SCLC LM.

Published: April 2024

Abstract
Objectives
To investigate the factors associated with voluntary HIV counseling and testing (VCT) among young students engaging in casual sexual activity and to establish a scientific rationale for developing targeted intervention strategies for preventing HIV/AIDS in this population.

Methods
Stratified cluster sampling was used to conduct a survey using questionnaires to collect demographic and behavioral information for statistical analysis.

Results
Data from 611 young students, who reported engaging in casual sexual activity, were included in the statistical analysis. Among these, 68 (11.13%) students underwent the VCT. Among young students who engaged in casual sexual activity, those who were non-Zhejiang residents (adjusted odds ratio [aOR]: 2.11; 95% Confidence Interval [CI]: 1.17–3.80), those who had received AIDS-themed lectures or health education courses from the school in the past year (aOR = 3.96, 95% CI = 1.49–10.50), those who had received HIV risk self-assessment conducted by the school in the past year (aOR = 2.31, 95% CI = 1.17–4.59), and those who had engaged in commercial sex activity in the past year (aOR = 1.98, 95% CI = 1.07–3.66) were more inclined to have undergone VCT. Male students (aOR = 0.37, 95% CI = 0.18–0.77) and those who used condoms consistently during casual sexual activity (aOR = 0.45, 95% CI = 0.21–0.97) were less likely to undergo VCT.

Conclusion
Casual sexual activity was relatively prevalent among young students, posing a potential risk for HIV transmission. These findings will be instrumental in the development more effective HIV prevention and control strategies for young students. Additionally, it highlights the necessity of promoting and popularizing VCT among young students without Zhejiang province residency, who are involved in commercial sexual activity, and/or those who lacking HIV education. Moreover, additional research and implementation of refined HIV behavioral interventions specifically tailored to young students are necessary to enhance their awareness and knowledge of HIV prevention.

Abstract
Background
It is important to understand the sexual and reproductive health (SRH) needs of adolescents from the adolescents themselves to address their needs properly. Hence, this paper provides new knowledge on the information needs on SRH among adolescent boys and girls in selected secondary schools in Ebonyi state, southeast Nigeria.

Method
A comparative assessment was conducted among adolescent boys and girls in public secondary schools that received a specific school-based SRH intervention (group A) and those that did not receive the intervention (group B). These schools were spread across six urban and rural local government areas in Ebonyi state, southeast Nigeria. A structured interviewer-administered questionnaire was used to collect data from 514 adolescents aged 13 to 18 on their stated needs for SRH information and services. Categorical variables were compared using the Chi-square test, and predictors were determined using logistic regression analysis. The statistical significance was determined at p < 0.05.

Result
Majority of the adolescents (82% of intervention group and 92% of non-intervention group) identified puberty and pubertal changes as perceived SRH information need for adolescents (χ2 = 7.94; p-value = 0.01). Adolescents who received SRH intervention have 3.13 (p < 0.001) times the odds of perceiving the need for adolescents to be provided with SRH information than adolescents who did not receive SRH intervention. The odds of perceiving the need for adolescents to be provided with SRH information for adolescents who reside in urban communities are 0.31 (p < 0.001) times the odds for adolescents who resides in rural communities. That is, the perception odds are higher adolescents who reside in rural communities. Multivariate regression of specific SRH information showed the location of residence as a strong predictor of adolescents’ perceived need for information on ‘puberty and pubertal changes’ (OR = 0.30; p = 0.001), ‘safe sex and sexual relations’ (OR = 0.33; p < 0.001) and ‘prevention of pregnancy and use of contraceptives’ (OR = 0.28; p < 0.001). Adolescents in senior secondary school have 2.21 (p = 0.002) times the odds of perceiving the need for adolescents to be provided with specific SRH information than adolescents who are in junior secondary school.

Conclusion
Adolescents’ age, location of residence, and study group were found to be strong predictors of SRH information needs. This suggests the need for in-school adolescents to be provided with substantial and continuous SRH information for healthy living and making informed SRH choices. In developing SRH interventions that will achieve optimal effectiveness in the lives of adolescents in school, different demographic factors should be considered for context-specific and appropriate strategies.
Transient pulmonary and gastric bleeding after iopamidol administration in a patient with marginal zone lymphoma: a case report
Authors: Xu Weixian , Chen Miaozhen , Liu Songtao , Su Yi , Zhang Yunhai 
Published: April 2024

Abstract
Background
Iopamidol is a non-ionic, water-soluble iodine contrast agent that is considered safe for intravenous or intra-arterial administration and is widely used both in the general population and in patients undergoing oncological treatment. While adverse reactions to iopamidol have been documented, to date, no pulmonary and gastric hemorrhages induced by iopamidol have been reported in oncology patients. We report the first case of this complication.

Case presentation
We report the case of a 60-year-old woman with marginal zone lymphoma who was receiving antineoplastic therapy. As part of the investigation for the condition, she underwent chest enhancement CT with iopamidol. Shortly thereafter(within five minutes), she experienced hemoptysis and hematemesis. She was intubated and admitted to the intensive care unit. Pre- and post-contrast images demonstrated the course of the hemorrhage. Flexible bronchoscopy and gastroscopy on the following day showed no active bleeding, and the patient recovered completely after antiallergy treatment. We speculate that contrast-induced hypersensitivity was the most likely cause of the transient pulmonary and gastric bleeding.

Conclusion
Although rare, the complications of iopamidol, which may cause allergic reactions in the lungs and stomach, should be considered.
Unusual cause of muscle weakness, type II respiratory failure and pulmonary hypertension: a case report of ryanodine receptor type 1(RYR1)-related myopathy
Authors: Chen Yinong , Zhang Shuai , Lu Xin , Xie Wanmu , Wang Chen , Zhai Zhenguo 
Published: April 2024

Abstract
Background
Patients with congenital myopathies may experience respiratory involvement, resulting in restrictive ventilatory dysfunction and respiratory failure. Pulmonary hypertension (PH) associated with this condition has never been reported in congenital ryanodine receptor type 1(RYR1)-related myopathy.

Case presentation
A 47-year-old woman was admitted with progressively exacerbated chest tightness and difficulty in neck flexion. She was born prematurely at week 28. Her bilateral lower extremities were edematous and muscle strength was grade IV−. Arterial blood gas analysis revealed hypoventilation syndrome and type II respiratory failure, while lung function test showed restrictive ventilation dysfunction, which were both worse in the supine position. PH was confirmed by right heart catheterization (RHC), without evidence of left heart disease, congenital heart disease, or pulmonary artery obstruction. Polysomnography indicated nocturnal hypoventilation. The ultrasound revealed reduced mobility of bilateral diaphragm. The level of creatine kinase was mildly elevated. Magnetic resonance imaging showed myositis of bilateral thigh muscle. Muscle biopsy of the left biceps brachii suggested muscle malnutrition and congenital muscle disease. Gene testing revealed a missense mutation in the RYR1 gene (exon33 c.C4816T). Finally, she was diagnosed with RYR1-related myopathy and received long-term non-invasive ventilation (NIV) treatment. Her symptoms and cardiopulmonary function have been greatly improved after 10 months.

Conclusions
We report a case of RYR1-related myopathy exhibiting hypoventilation syndrome, type II respiratory failure and PH associated with restrictive ventilator dysfunction. Pulmonologists should keep congenital myopathies in mind in the differential diagnosis of type II respiratory failure, especially in patients with short stature and muscle weakness.
Long-term follow-up after the treatment of impacted canines in the maxilla causing severe root resorption of the lateral incisors: two case reports
Authors: LI Ning , YANG Liu , YANG Qian , WANG Hongning , XU Xiaolin , WANG Tiejun 
Published: April 2024

Abstract
Background
Root resorption of adjacent teeth due to impacted canines is common, and orthodontic treatment often leads to secondary resorption or even loss of adjacent roots. Clinical reports of long-term stability after treatment are rare.

Case presentation
This study reports two cases of maxillary impacted canines resulting in severe root resorption of the adjacent lateral incisors. Surgical exposure, orthodontic retraction, and alignment of the impacted canines were successful in both cases, and the resorbed lateral incisors were stable with no significant loosening and normal pulp vitality after treatment and at the 5- and 10-year follow-up appointments.

Conclusions
Light orthodontic force may be used to move adjacent teeth with root resorption due to tooth obstruction. The path and direction in which the teeth are moved must be specifically designed so that the adjacent roots are not resorbed and so long-term stability can be achieved.
