Authors: Zhang Rui , Jia Shijun , Zhai Linhan , Wu Feng , Zhang Shuang , Li Feng
Published: April 2024

Objectives

The aim of the study is to assess the efficacy of the established computed tomography (CT)-based radiomics nomogram combined with radiomics and clinical features for predicting muscle invasion status in bladder cancer (BCa).

Methods

A retrospective analysis was conducted using data from patients who underwent CT urography at our institution between May 2018 and April 2023 with urothelial carcinoma of the bladder confirmed by postoperative histology. There were 196 patients enrolled in all, and each was randomized at random to either the training cohort (n = 137) or the test cohort (n = 59). Eight hundred fifty-one radiomics features in all were retrieved. For feature selection, the significance test and least absolute shrinkage and selection operator (LASSO) approaches were utilized. Subsequently, the radiomics score (Radscore) was obtained by applying linear weighting based on the selected features. The clinical and radiomics model, as well as radiomics-clinical nomogram were all established using logistic regression. Three models were evaluated using analysis of the receiver operating characteristic curve. An area under the curve (AUC) and 95% confidence intervals (CI) as well as specificity, sensitivity, accuracy, negative predictive value, and positive predictive value were included in the analysis. Radiomics-clinical nomogram’s performance was assessed based on discrimination, calibration, and clinical utility.

Results

After obtaining 851 radiomics features, 12 features were ultimately selected. Histopathological grading and tortuous blood vessels were included in the clinical model. The Radscore and clinical histopathology grading were among the final predictors in the unique nomogram. The three models had an AUC of 0.811 (95% CI, 0.742–0.880), 0.845 (95% CI, 0.781–0.908), and 0.896 (95% CI, 0.846–0.947) in the training cohort and in the test cohort they were 0.808 (95% CI, 0.703–0.913), 0.847 (95% CI, 0.739–0.954), and 0.887 (95% CI, 0.803–0.971). According to the DeLong test, the radiomics-clinical nomogram’s AUC in the training cohort substantially differed from that of the clinical model (AUC: 0.896 versus 0.845, p = 0.015) and the radiomics model (AUC: 0.896 versus 0.811, p = 0.002). The Delong test in the test cohort revealed no significant difference among the three models.

Conclusions

CT-based radiomics-clinical nomogram can be a useful tool for quantitatively predicting the status of muscle invasion in BCa.

Authors: Masrour Mahdi , Zare Amir , Presedo Ana , Nabian Mohammad Hossein
Published: April 2024

Background

Spasticity can significantly affect a patient’s quality of life, caregiver satisfaction, and the financial burden on the healthcare system. Baclofen is one of only a few options for treating spasticity. The purpose of this study is to investigate the impact of intrathecal baclofen (ITB) therapy on severe40.23 spasticity and motor function in patients with cerebral palsy.

Methods

We conducted a systematic review in PubMed, Scopus, Ovid, and the Cochrane Library in accordance with the PRISMA guidelines. We included studies based on eligibility criteria that included desired participants (cerebral palsy patients with spasticity), interventions (intrathecal baclofen), and outcomes (the Ashworth scales and the Gross Motor Function Measure [GMFM]). The within-group Cohen’s d standardized mean differences (SMD) were analyzed using the random effect model.

Results

We screened 768 papers and included 19 in the severity of spasticity section and 6 in the motor function section. The pre-intervention average spasticity score (SD) was 3.2 (0.78), and the post-intervention average score (SD) was 1.9 (0.72), showing a 40.25% reduction. The SMD for spasticity reduction was − 1.7000 (95% CI [-2.1546; -1.2454], p-value < 0.0001), involving 343 patients with a weighted average age of 15.78 years and a weighted average baclofen dose of 289 µg/day. The SMD for the MAS and Ashworth Scale subgroups were − 1.7845 (95% CI [-2.8704; -0.6986]) and − 1.4837 (95% CI [-1.8585; -1.1088]), respectively. We found no relationship between the participants’ mean age, baclofen dose, measurement time, and the results. The pre-intervention average GMFM (SD) was 40.03 (26.01), and the post-intervention average score (SD) was 43.88 (26.18), showing a 9.62% increase. The SMD for motor function using GMFM was 0.1503 (95% CI [0.0784; 0.2223], p-value = 0.0030), involving 117 patients with a weighted average age of 13.63 and a weighted average baclofen dose of 203 µg/day. In 501 ITB implantations, 203 medical complications were reported, including six new-onset seizures (2.96% of medical complications), seven increased seizure frequency (3.45%), 33 infections (16.26%), eight meningitis (3.94%), and 16 cerebrospinal fluid leaks (7.88%). Delivery system complications, including 75 catheter and pump complications, were also reported.

Conclusion

Despite the risk of complications, ITB has a significant impact on the reduction of spasticity. A small but statistically significant improvement in motor function was also noted in a group of patients.
Establishment of a placental lncRNA-mRNA expression network for early-onset preeclampsia
Authors: Chen Ya , Zhang Ying , Xie Siyu , Zhou Xiangdong , Zhu Lina , Cao Yunxia
Published: April 2024

Background

This study aimed to establish a placental long non-coding RNA (lncRNA)-mRNA expression network for early-onset preeclampsia (early-onset PE).

Methods

The RNA sequencing data of the GSE14821 dataset were acquired. Several crucial lncRNAs and mRNAs were exerted based on the differential expression analysis of lncRNA and mRNA. By analyzing the differentially expressed lncRNA and mRNA, we constructed a regulatory network to explore the mechanism of the lncRNA in early onset preeclampsia.

Results

A total of 4436 differentially expressed lncRNAs (DElncRNAs) were identified in early-onset PE placenta samples compared with control placenta samples. Pearson correlation analysis revealed significant correlations between 3659 DElncRNAs and 372 DEmRNAs. KEGG analysis showed that the DEmRNAs were enriched in cytokine-cytokine receptor and hypoxia-inducible factor (HIF)-1 pathways. Several well-known early-onset PE-related mRNAs, such as vascular endothelial growth factor A (VEGFA) and VEGF receptor 1 (FLT1), were involved in the two pathways. Weighted gene co-expression network analysis and cis-regulatory analysis further suggested the involvement of the two pathways and potential DElncRNA-DEmRNA interactions in early-onset PE. Moreover, the upregulation of representative DElncRNAs, such as RP11-211G3.3 and RP11-65J21.3, and DEmRNAs, such as VEGFA and FLT1, were validated in clinical placenta samples from patients with early-onset PE by quantitative reverse transcription PCR. Importantly, overexpression of RP11-65J21.3 significantly promoted the proliferation of HTR-8 trophoblast cells at 72 h after transfection.

Conclusions

In conclusion, we identified placental DElncRNAs of early-onset PE and established a DElncRNA-DEmRNA network that was closely related to the cytokine-cytokine receptor and HIF-1 pathways. Our results provide potential diagnostic markers and therapeutic targets for early-onset PE management.
Association of the TRIM family protein with survival outcomes and clinicopathological features in colorectal cancer: a systematic review and meta-analysis
Authors: Wu Ying , Chen Chen , Hua Xian , Zhao Chunhua , Min Han
Published: April 2024

Background

The tripartite motif (TRIM) proteins have been reported to play crucial roles in various malignancies. However, the clinical significance of TRIM proteins in colorectal cancer (CRC) remains controversial. This study aimed to evaluate the association between TRIM proteins and the clinicopathological features and survival outcomes in patients with CRC.

Methods

We performed a meta-analysis to investigate whether TRIM is a prognostic factor in CRC. PubMed, Embase, Web of Science, CNKI and Weipu databases were searched to identify eligible studies that evaluated the association between TRIM proteins and overall survival (OS), as well as the clinicopathological features of patients with CRC. Hazard ratios (HR) or odds ratios (OR) with 95% confidence interval (CI) were derived and pooled using a fixed-effects model.

Results

From inception to March 2023, we extracted study characteristics and prognostic data for each identified study. Twelve studies enrolling 1608 patients were eligible for inclusion. Data on OS and recurrence-free survival (RFS) were available for 12 and 2 studies, respectively. The pooled analysis results showed a significant correlation between the elevated TRIM proteins and shorter OS (HR = 2.42, 95% CI: 1.96–2.99) and worse RFS (HR = 2.51, 95% CI: 1.78–3.54) in patients with CRC. The combined ORs indicated that TRIM protein over-expression was significantly associated with advanced TNM stage (OR = 2.26, 95% CI: 1.25–4.10), deep tumor invasion (OR = 2.01, 95% CI: 1.04–3.88), lymph node metastasis (OR = 2.99, 95% CI: 2.19–4.09) and perineural invasion (OR = 1.95, 95% CI: 1.18–3.23).

Conclusions

Our findings suggest that TRIM proteins can predict tumor progression and poor prognosis in CRC. Therefore, TRIM proteins may be promising therapeutic targets for patients with CRC.

Graphical Abstract
Comparison of neurally adjusted ventilatory assist and synchronized intermittent mandatory ventilation in preterm infants after patent ductus arteriosus ligation: a retrospective study
Authors: Lin Hui-Zi , Lin Yun-Feng , Zheng Yi-Rong
Published: April 2024

Objective

This study aimed to compare the efficacy of neurally adjusted ventilatory assist (NAVA) to synchronized intermittent mandatory ventilation (SIMV) in preterm infants requiring mechanical ventilation after patent ductus arteriosus (PDA) ligation.

Methods

A retrospective analysis was conducted on intubated preterm infants who underwent PDA ligation at our hospital from July 2021 to January 2023. Infants were divided into NAVA or SIMV groups based on the ventilation mode after surgery.

Results

Fifty preterm infants were included. During treatment, peak inspiratory pressure (PIP) and mean airway pressure (MAP) were lower with NAVA compared to SIMV (PIP: 19.1 ± 2.9 vs. 22.4 ± 3.6 cmH2O, P < 0.001; MAP: 9.1 ± 1.8 vs. 10.9 ± 2.7 cmH2O, P = 0.002). PaO2 and PaO2/FiO2 were higher with NAVA (PaO2: 94.0 ± 11.7 vs. 84.8 ± 15.8 mmHg, P = 0.031; PaO2/FiO2: 267 [220–322] vs. 232 [186–290] mmHg, P = 0.025). Less sedation was required with NAVA (midazolam: 1.5 ± 0.5 vs. 1.1 ± 0.3 μg/kg/min, P < 0.001).

Conclusion

Compared to SIMV, early use of NAVA post PDA ligation in preterm infants was associated with decreased PIP and MAP. Early NAVA was also associated with reduced sedation needs and improved oxygenation. However, further studies are warranted to quantify the benefits of NAVA ventilation.

Authors: Guo Yujun , Lu Wenjun , Zhang Ze’nan , Liu Hengchen , Zhang Aodan , Zhang Tingting , Wu Yang , Li Xiangqi , Yang Shulong , Cui Qingbo , Li Zhaozhu
Published: April 2024

Background

Wilms’ tumor (WT) is the most common renal tumor in childhood. Pyroptosis, a type of inflammation-characterized and immune-related programmed cell death, has been extensively studied in multiple tumors. In the current study, we aim to construct a pyroptosis-related gene signature for predicting the prognosis of Wilms’ tumor.

Methods

We acquired RNA-seq data from TARGET kidney tumor projects for constructing a gene signature, and snRNA-seq data from GEO database for validating signature-constructing genes. Pyroptosis-related genes (PRGs) were collected from three online databases. We constructed the gene signature by Lasso Cox regression and then established a nomogram. Underlying mechanisms by which gene signature is related to overall survival states of patients were explored by immune cell infiltration analysis, differential expression analysis, and functional enrichment analysis.

Results

A pyroptosis-related gene signature was constructed with 14 PRGs, which has a moderate to high predicting capacity with 1-, 3-, and 5-year area under the curve (AUC) values of 0.78, 0.80, and 0.83, respectively. A prognosis-predicting nomogram was established by gender, stage, and risk score. Tumor-infiltrating immune cells were quantified by seven algorithms, and the expression of CD8( +) T cells, B cells, Th2 cells, dendritic cells, and type 2 macrophages are positively or negatively correlated with risk score. Two single nuclear RNA-seq samples of different histology were harnessed for validation. The distribution of signature genes was identified in various cell types.

Conclusions

We have established a pyroptosis-related 14-gene signature in WT. Moreover, the inherent roles of immune cells (CD8( +) T cells, B cells, Th2 cells, dendritic cells, and type 2 macrophages), functions of differentially expressed genes (tissue/organ development and intercellular communication), and status of signaling pathways (proteoglycans in cancer, signaling pathways regulating pluripotent of stem cells, and Wnt signaling pathway) have been elucidated, which might be employed as therapeutic targets in the future.

Authors: Amiri Nastaran , Karami Kimia , Valizadeh Fatemeh , Mokhayeri Yaser
Published: April 2024

Background

Adequate sleep and exercise are important components of the human lifestyle. Paying attention to these two factors is very important to improve the condition of children with type 1 diabetes. Therefore, this study aimed to investigate the effect of exercise on sleep habits in children with type 1 diabetes.

Material & methods

62 children with type 1 diabetes participated in this clinical trial. They will be divided into the intervention group (31) and the control group (31). Sleep habits were measured using the Children’s Sleep Habits Questionnaire (CSHQ). All children’s parents completed the CSHQ. The intervention for the experimental group consisted of 8 weeks of regular exercise program. The exercise program was prepared as an educational video and provided to parents. Paired sample t-test and ANCOVA test were used with SPSS 23.

Results

62 children with an average age of 9.32 ± 2.02 were studied. Fifty-four and eight% of the children were girls and the rest were boys. The analysis of the variance test showed a significant difference (F = 144.72, P ≤ 0.01) between the average score of the sleep habits of the control group (62.45 ± 5.12) and the experimental group (47.06 ± 4.39).

Conclusion

Sleep habits in the experimental group improved after 8 weeks of exercise training using educational videos. Exercise as a non-pharmacological treatment is an effective way to manage diabetes and improve sleep quality in diabetic children.
Supportive and non-supportive social experiences following suicide loss: a qualitative study
Authors: Marek Franziska , Oexle Nathalie
Published: April 2024

Background

Suicide bereavement entails profound social stressors, including stigma and communication barriers, which can impair social support for suicide loss survivors (SLS). Despite recognized benefits of empathetic interactions, social support, and self-disclosure in mitigating adverse mental health outcomes after suicide loss, we lack a comprehensive understanding of the factors influencing perceived social support among SLS within their broader social environments. To address this gap, our study explores the diverse social experiences of SLS beyond their immediate circles. Specifically, we identify characteristics that define both supportive and non-supportive social experiences of SLS, as well as the facilitators and barriers to social support in the context of suicide bereavement.

Methods

In 2022, we conducted structured online individual interviews with a diverse sample of 18 SLS in Germany. We analyzed these interviews using qualitative content analysis.

Results

We examined the social experiences of SLS across three phases and social contexts: (1) the immediate aftermath of the loss; (2) during bereavement practices; and (3) over time. Our findings show that proactive responses and personalized mourning rituals significantly enhance SLS’ sense of community support, while encounters characterized by avoidance or intrusive curiosity lead to feelings of isolation. Over time, supportive interactions often emerge from peers with similar experiences, promoting openness and shared vulnerability. Conversely, superficial engagement, along with experiences of others depersonalizing and avoiding conversations about the loss, contribute to a sense of marginalization.

Conclusions

Our findings highlight the importance of proactive engagement and open dialogue, calling for societal and communicative shifts toward inclusive and compassionate approaches in addressing suicide loss. This study underscores the need for comprehensive strategies that enhance both suicide and grief literacy and address the taboo and stigma surrounding suicide, ultimately fostering supportive social environments for SLS.
Does health literacy mediate the relationship between socioeconomic status and health related outcomes in the Belgian adult population?
Authors: Berete Finaba , Gisle Lydia , Demarest Stefaan , Charafeddine Rana , Bruyère Olivier , Van den Broucke Stephan , Van der Heyden Johan
Published: April 2024

Background

Health literacy (HL) has been put forward as a potential mediator through which socioeconomic status (SES) affects health. This study explores whether HL mediates the relation between SES and a selection of health or health-related outcomes.

Methods

Data from the participants of the Belgian health interview survey 2018 aged 18 years or older were individually linked with data from the Belgian compulsory health insurance (n = 8080). HL was assessed with the HLS-EU-Q6. Mediation analyses were performed with health behaviour (physical activity, diet, alcohol and tobacco consumption), health status (perceived health status, mental health status), use of medicine (purchase of antibiotics), and use of preventive care (preventive dental care, influenza vaccination, breast cancer screening) as dependent outcome variables, educational attainment and income as independent variables of interest, age and sex as potential confounders and HL as mediating variable.

Results

The study showed that unhealthy behaviours (except alcohol consumption), poorer health status, higher use of medicine and lower use of preventive care (except flu vaccination) were associated with low SES (i.e., low education and low income) and with insufficient HL. HL partially mediated the relationship between education and health behaviour, perceived health status and mental health status, accounting for 3.8–16.0% of the total effect. HL also constituted a pathway by which income influences health behaviour, perceived health status, mental health status and preventive dental care, with the mediation effects accounting for 2.1–10.8% of the total effect.

Conclusions

Although the influence of HL in the pathway is limited, our findings suggest that strategies for improving various health-related outcomes among low SES groups should include initiatives to enhance HL in these population groups. Further research is needed to confirm our results and to better explore the mediating effects of HL.
Relative and absolute inequalities in cerebrovascular disease mortality rates: exploring the influence of socioeconomic status and urbanization levels in Taiwan
Authors: Lin Wen-Yu , Lin Ping-Yi , Liang Wen-Miin , Kuo Hsien-Wen
Published: April 2024

Background/Objective

Limited evidence exists regarding the socioeconomic inequalities in cerebrovascular disease (CBD) mortality at different urbanization levels. Therefore, this study was conducted to assess the socioeconomic inequalities and urbanization levels in township-based CBD mortality in Taiwan.

Methods

Socioeconomic variables, including the percentages of low-income households, individuals with a university education and above, and tax payments, were measured at the township level from 2011 to 2020. Urbanization was also determined by the national survey and divided into seven levels. Age-standardized mortality rate (ASMR) of CBD was calculated using a Geographic Information System (GIS) in 358 townships. The effects of socioeconomic variables and urbanization levels on relative and absolute inequalities in township-based CBD mortality rates were examined.

Results

Significant differences in ASMR of CBD were observed across all socioeconomic status indicators over the years. Higher proportions of low-income households were associated with higher ASMR of CBD. Conversely, there were negative correlations between higher proportions of individuals with a university education and above and tax payments with ASMR of CBD. The regression analysis indicated significant impacts of relative and absolute socioeconomic inequalities on ASMR of CBD. Additionally, a moderation effect of socioeconomic variables and urbanization on CBD mortality rates was observed, with rural areas showing sensitivity to these factors.

Conclusion

Although ASMR of CBD showed significant decreases over time, socioeconomic inequalities in CBD mortality rates persist. Interventions targeting socioeconomic inequalities in health outcomes, especially in rural areas, are needed to address this issue.
Goal setting in people with low back pain attending an education and exercise program (GLA:D Back) and the impact of demographic factors
Authors: Gregersen Mette H.M. , Nielsen Kristine R. , Lynge Nana H. , Heiberg Bibi D. , Hartvigsen Jan , Kawchuk Greg , Kongsted Alice
Published: April 2024

Background

Individual goal setting is a fundamental element in self-management supportive interventions, serving to guide actions and enhance motivation for engagement. Despite this, little is known about the goals people with back pain have and to what extent these differ across genders, age groups and geographical location. This study aimed to elucidate this by first describing individual goals set by Danish and Canadian participants in a self-management intervention for people with back pain using the ICF framework; then, determining what proportion of these goals met criteria for being specific, measurable, acceptable, and time bound, and finally, by investigating differences between countries, sexes, and age groups.

Methods

In a cross-sectional study conducted August 2018 to June 2020, 394 Danish and 133 Canadian (Alberta Province) participants defined their individual goals of participating in a self-management programme involving patient education and supervised exercises. The goals were linked to the ICF framework. Distribution of goals was compared between countries, sexes, and age groups.

Results

Goals most often related to the ICF component of ‘Activity and Participation’. The most prevalent goals were “Walking” (DK: 20%; CA: 15%) and “Maintaining a body position” (DK: 17%; CA: 22%). Only few goals differed between populations, age and sex. All elements of SMART goal setting were recorded for 88% of Danish and 94% of Alberta participants.

Conclusions

People with low back pain attending a self-management programme established goals according to the SMART criteria and focused primarily on activity. Goals were similar across countries and showed few differences across sex and age groups. The high number of different goals points to the need for individualised person-centred care.
Comparison of endoscopic thyroidectomy via the oral vestibule approach and the areola approach for papillary thyroid carcinoma
Authors: Liu Yingying , Lin Fusheng , Yan Wei , Lin Ende , Kuang Penghao , Hong Xiaoquan , Lu Yizhuo , Wu Guoyang , Li Lianghui
Published: April 2024

Background

The endoscopic thyroidectomy areola approach (ETAA) has been widely applied for papillary thyroid carcinoma (PTC), but leaves scars and is not truly minimally invasive. The oral vestibular approach (ETOVA) leaves no scars and is even more minimally invasive. However, there have been few comparative studies of ETAA and ETOVA for PTC. The purpose of our research was to compare two PTC treatment methods in terms of feasibility, safety, efficacy, and cosmetic results.

Methods

A total of 129 patients with PTC underwent thyroidectomy combined with central lymph node dissection by the same surgeon. Among them, 79 patients underwent the ETOVA, and the others underwent the ETAA. We compared the two groups in terms of operative outcomes, postoperative complications, and cosmetic results.

Results

No significant differences were found in the clinical characteristics between the ETOVA and ETAA groups. There were no significant differences in the number of removed lymph nodes (P = 0.279) or the number of positive lymph nodes (P = 0.569), but the ETOVA group had a higher number of removed lymph nodes. There was also no significant difference in blood loss volume(P = 0.180), postoperative drainage volume (P = 0.063), length of hospital stay (P = 0.182), transient RLN injury rate (P = 1.000), permanent RLN injury rate (P = 1.000), or recurrence rate (P = 1.000). The ETOVA was a longer operation than the ETAA was (P < 0.01). The ETOVA group had less pain (VAS 1: P < 0.01, VAS 3: P = 0.001), less neck discomfort (1 month after surgery: P = 0.009, 3 months after surgery: P = 0.033), and better cosmetic results (P = 0.001).

Conclusions

The ETOVA is not inferior to the ETAA in terms of safety and curability of PTC and is advantageous in terms of central lymph node dissection, minimal invasiveness, and cosmetic results.

Energy expenditure related biomarkers following bariatric surgery: a prospective six-month cohort study
Authors: Hatami Mahsa , Javanbakht Mohammad Hassan , Haghighat Neda , Sohrabi Zahra , Yavar Rahman , Pazouki Abdolreza , Farsani Gholamreza Mohammadi
Published: April 2024

Background

Mitochondria dysfunction is one of the major causes of insulin resistance, and other countless complications of obesity. PGC-1α, and UCP-2 play key roles in energy expenditure regulation in the mitochondrial thermogenesis. However, the effects of bariatric surgery on the level of PGC-1α and UCP-2 and their relationships are unclear.

Objective

This study aimed to investigate the effect of bariatric surgery on key pathways in energy, and to assess the potential predictive role of body composition and metabolic parameters in this regard.

Settings

Hazrat-e Rasool General Hospital, Center of Excellence of International Federation for Surgery of Obesity.

Methods

This prospective cohort study was carried out on 45 patients with morbid obesity who underwent Roux-en-Y gastric bypass surgery. The patients have evaluated three-time points at baseline, three, and six months after the surgery. Body composition components, the levels of PGC-1α, UCP-2, and metabolic parameters were measured three times during this study.

Results

Significant changes in TWL%, EBMIL%, and metabolic lab tests were observed at three- and six months post-surgery (P < 0.001). The PGC-1α and UCP-2 had a significant increase three and then six-month post-operation compared with the baseline (P < 0.001). Moreover, multivariate linear regression analysis identified that the changing trend of PGC-1α was associated with insulin, uric Acid, HOMA-IR, fat mass and trunk fat mass. UCP-2 was associated with TSH, AST, fat mass and FFM.

Conclusions

Bariatric surgery has been shown to have a positive effect on UCP-2 and PGC-1α levels, as well as body composition and metabolic parameters. As a result, it is believed that bariatric surgery could improve thermogenesis and energy expenditure by enhancing mitochondrial biogenesis and function. However, further studies are needed to fully understand the precise mechanisms and possible causal relationship.
Unveiling the hidden: identification and management of overlooked blood vessels in laparoscopic left hemicolectomy for splenic flexure cancer
Authors: Luo Wenjun , Chen Peng , Du Qiang , Yang Lie , Zhou Zongguang
Published: April 2024

Background

During laparoscopic left hemicolectomy procedures, a previously overlooked consistently thick blood vessel within the gastrocolic ligament near the splenic hilum may contribute to post-operative bleeding complications. The purpose of this study was to investigate the identification and management of the previously overlooked blood vessel.

Methods

This is a retrospective descriptive study of patients undergoing laparoscopic left colectomy for splenic fexure cancer conducted at a national gastrointestinal surgery centre in China. Consecutive patients with splenic fexure cancer who underwent laparoscopic left colectomy using our“five-step process”(n = 34) between January 2021 and July 2023 were included.

Results

The vessels can be effectively exposed using the aforementioned “five-step process.” It was observed that the overlooked vessels consistently present in all patients were identified as the omental branch of the left gastroepiploic artery and vein.

Conclusion

We have identified the origin of previously overlooked blood vessels and recommended a safe method for their management. This may offer advantages to colorectal surgeons performing laparoscopic left colectomy for splenic flexure cancer
Concomitant ectopic Enterobius vermicularis infection in uterine cervical cancer
Authors: Takač Iztok , Kavalar Rajko , Lovrec Matija Rudolf , Lovrec Vida Gavrić
Published: April 2024

Background

Enterobius vermicularis (E. vermicularis), also referred to as pinworm, is a widespread human intestinal parasite which predominantly occurs in young children, making their caretakers a population at risk for the transmission of this helminth. It can occasionally affect extraintestinal organs and tissues, including the female genital tract. Infestation can be asymptomatic or manifest as different kinds of gynaecological disorders, such as pelvic inflammation mimicking tumours, abnormal uterine bleeding, or vaginitis. Diagnosis is made by identifying ova in the sample collected from the perineal skin using a transparent adhesive tape or microscopic examination of resected tissue. Mebendazole is the first-line medication and should also be administered to all household members.

Case presentation

We present a case of a patient who had undergone surgery for invasive cervical cancer with an accidental finding of E. vermicularis eggs in the cervix.

Conclusions

Although not very common, infestation with E. vermicularis should be considered in differential diagnoses of various gynaecological disorders accompanied by histological findings of granulomatous inflammation.
The effect of ovarian response parameters and the synergistic effect of assisted reproduction of poor ovarian response treated with platelet rich plasma: systematic review and meta-analysis
Authors: Li Wanjing , Xu Jinbang , Deng Disi
Published: April 2024

Background

Poor ovarian response (POR) patients often encounter cycle cancellation and egg retrieval obstacles in assisted reproductive technology. Platelet rich plasma (PRP) ovarian injection is a potential treatment method, but the treatment methods are different, and the treatment results are controversial.

Objective

This study adopts a systematic review and meta-analysis method based on clinical research to explore the efficacy and safety of PRP injection on POR.

Method

The following databases were searched for research published before March 2023; Medline (via PubMed), Web of Science, Scopus, Cochrane Library, Embase, Cochrane Library, and China National Knowledge Infrastructure Database (CNKI). The literature was then screened by two independent researchers, who extracted the data and evaluated its quality. Research was selected according to the inclusion criteria, and its quality was evaluated according to the NOS standard Cohort study. The bias risk of the included study was assessed with STATE 14.0. RevMan 5.3 software was used for meta-analysis.

Main results

Ten studies were included in the analysis, including 7 prospective cohort studies and 3 retrospective studies involving 836 patients. The results showed that after PRP treatment, follicle stimulating hormone (FSH) significantly decreased and anti-Mueller hormone (AMH) and luteinizing hormone (LH) significantly increased in POR patients, but estradiol did not change significantly; The number of antral follicles increased, and the number of obtaining eggs and mature oocytes significantly increased; The number of Metaphase type II oocytes, 2PN and high-quality embryos, and cleavage stage embryos significantly increased. In addition, the patient cycle cancellation rates significantly decreased. The rate of natural pregnancy assisted reproductive pregnancy and live birth increased significantly. Four reports made it clear that no adverse reactions were observed.

Conclusion

PRP may have the potential to improve pre-assisted reproductive indicators in POR patients, increase the success rate of in vitro fertilization-embryo transfer (IVF-ET) in POR patients, and improve embryo quality, and may be beneficial to the pregnancy outcome. There is no obvious potential risk in this study, but further clinical support is still needed.

Background

Infertility continued to be a major stressor among women with infertility during COVID-19pandemic. This study aimed to evaluate the impact of primary care posttraumatic stress disorder (PC-PTSD) on fertility problem of Iranian women with infertility during COVID-19 pandemic.

Method

In this cross-sectional study, 386 women with infertility completed the questionnaires of PC-PTSD-5 and Fertility Problem Inventory (FPI) at an infertility center between 2020 and 2022.

Results

The mean of fertility problems was 145.20 (± 32.31). In terms of FPI subscales, the means were as follows: Sexual concern 21.80 (± 7.58), social concern 26.53 (± 8.94), relationship concern 26.02 (± 9.18), need for parenthood concern 40.88 (± 8.98), and rejection of childfree lifestyle 29.96 (± 7.69). The highest mean of FPI subscales was related to the need for parenthood concern in women with infertility. The strongest correlation was found between the subscales of sexual concern and social concern followed by sexual concern and relationship concern. The variables of PC-PTSD were a predictor of fertility problems (β = 0.203, P < .0001). Additionally, the variables of PC-PTSDwere a predictor of sexual concern (β = 0.248, P < .0001), social concern (β = 0.237, P < .0001), relationship concern (β = 0.143, P < .020), and need for parenthood concern (β = 0.101, P < .010). After adjusting for demographic characteristics, there was a significant relationship between FPI with job (β=-0.118, P < .031), education (β=-0.130, P < .023), living place (β = 0.115, P < .035), smoking (β = 0.113, P < .036), relationship with husband (β = 0.118, P < .027), and PC-PTSD symptom (β = 0.158, P < .0001). In addition, the multivariate linear regression showed a significant association between sexual concern and education (β=-0.152, P < .008), smoking (β = 0.129, P < .018), PC-PTSD symptom (β = 0.207, P < .0001); social concern and job (β=-0.119, P < .033), PC-PTSD symptom (β = 0.205, P < .0001); relationship concern and education (β=-0.121, P < .033), living place (β = 0.183, P < .001), relationship with husband (β = 0.219, P < .0001); and rejection of childfree lifestyle and job (β=-0.154, P < .007).

Conclusion

Systematic PTSD screening during COVID-19 pandemic by healthcare providers can be uniquely used to identify, evaluate, and treat trauma-related health conditions in infertility settings, which can link women with infertility to mental health services. This can be novel and useful for future policymakers and practitioners in the infertility field.

Background

The primary healthcare system in Pakistan focuses on providing episodic, disease-based care. Health care for low-middle income communities is largely through a fee-for-service model that ignores preventive and health-promotive services. The growing burden of cardiovascular illnesses requires restructuring of the primary health care system allowing a community-to-clinic model of care to improve patient- and community-level health indicators.

Methods

We propose a model that integrates a Patient-Centered Medical Home (PCMH) with a Community-Based Health Information System (CBHIS) using hypertension (HTN) as an example. This protocol describes the integration and evaluation of the PCMH-CBHIS infrastructure through a population-based, observational, longitudinal study in a low-middle income, urban community in Pakistan. Participants are being enrolled in CBHIS and will be followed longitudinally over two years for HTN outcomes. A mixed-methods approach is adopted to evaluate the process of integrating PCMH with CBHIS. This involves building partnerships with the community through formal and informal meetings, focus group discussions, and a household health assessment survey (HAS). Community members identified with HTN are linked to PCMH for disease management. A customized electronic medical record system links community-level data with patient-level data to track changes in disease burden. The RE-AIM evaluation framework will be used to monitor community and individual-level metrics to guide implementation assessment, the potential for generalization, and the effectiveness of the PCMH in improving HTN-related health outcomes. Ethical clearance has been obtained from the Ethics Review Committee at Aga Khan University (2022-6723-20985).

Discussion

This study will evaluate the value of restructuring the primary care health system by ensuring systematic community engagement and measurement of health indicators at the patient- and community-level. While HTN is being used as a prototype to generate evidence for the effectiveness of this model, findings from this initiative will be leveraged towards strengthening the management of other acute and chronic conditions in primary care settings. If effective, the model can be used in Pakistan and other LMICs and resource-limited settings.

Background

Research on health resource allocation trends in ethnic minority and impoverished areas in China is limited since the 2009 Medical Reform. This study aimed to investigate the variations and inequalities in health resource distribution among ethnic minority, poverty-stricken, and non-minority regions in Sichuan Province, a multi-ethnic province in Southwest China, from 2009 to 2019.

Methods

The numbers of beds, doctors and nurses were retrospectively sourced from the Sichuan Health Statistics Yearbook between 2009 and 2019. All the 181 counties in Sichuan Province were categorized into five groups: Yi, Zang, other ethnic minority, poverty-stricken, and non-minority county. The Theil index, adjusted for population size, was used to evaluate health resource allocation inequalities.

Results

From 2009 to 2019, the number of beds (Bedp1000), doctors (Docp1000), and nurses (Nurp1000) per 1000 individuals in ethnic minority and poverty-stricken counties consistently remained lower than non-minority counties. The growth rates of Bedp1000 in Yi (140%) and other ethnic minority counties (127%) were higher than in non-minority counties (121%), while the growth rates of Docp1000 in Yi (20%) and Zang (11%) counties were lower than non-minority counties (61%). Docp1000 in 33% and 50% of Yi and Zang ethnic counties decreased, respectively. Nurp1000 in Yi (240%) and other ethnic minority (316%) counties increased faster than non-minority counties (198%). The Theil index for beds and nurses declined, while the index for doctors increased. Key factors driving increases in bed allocation include preferential policies and economic development levels, while health practitioner income, economic development levels and geographical environment significantly influence doctor and nurse allocation.

Conclusions

Preferential policies have been successful in increasing the number of beds in health facilities, but not healthcare workers, in ethnic minority regions. The ethnic disparities in doctor allocation increased in Sichuan Province. To increase the number of doctors and nurses in ethnic minority and poverty-stricken regions, particularly in Yi counties, more preferential policies and resources should be introduced.

Background

This study aimed to investigate variations of the oxidative status in cats affected by urethral obstruction (UO) under Feline Idiopathic Cystitis (FIC) and Bacterial Cystitis (BC), in comparison with a group of healthy subjects. In both groups, the levels of several markers (either direct or indirect) indicative of the oxidative attack and of the antioxidant response were analyzed on plasma and urine samples. In particular, the plasma samples were evaluated for nitric oxide (NO), hydroperoxides derived by reactive oxygen activity (d-ROMs test), superoxide anion (O2−), glutathione peroxidase activity (GPx), superoxide dismutase activity (SOD), and ferric reducing antioxidant power (FRAP test); while on urine the levels of NO, d-ROMs, FRAP, SOD, malondialdehyde (MDA) and 8-hydroxydeoxyguanosine (8-OHdG) were measured. Urine of UO patients was also subjected to urine-culture test.

Results

The analytical data on plasma showed that UO, independently of the FIC or BC etiology, induced the insurgence of oxidative stress conditions at the systemic level. In the urine of the UO patients, except for SOD that increased, the markers of redox status were markedly decreased due probably their compromised filtration, thus suggesting involvement of renal function (assessed also by the high levels of plasma creatinine and proteinuria) with no oxidative damage of the lower urinary tract. Moreover, the adoption of a novel oxidative stress index’ (OSI) allowed to establish, by means of a numerical value, the different degrees of oxidative stress conditions for single UO patients, both in terms of oxidative attack and antioxidant response.

Conclusions

Feline urethral obstruction, induced by Idiopathic Cystitis and Bacterial Cystitis, causes oxidative stress conditions at the systemic level that do not interest the lower urinary tract. Despite to the high variability of the profiles of oxidative stress indexes both in healthy and UO patients, the determination of OSI made possible the evaluation of their single degrees of oxidative stress. Possibly the results of this investigation can be compared with those of correspondent pathologies both in humans and in other animal species.

Background

Idiopathic pulmonary fibrosis (IPF) is a debilitating and progressive lung disease of unknown aetiology, characterized by the relentless deposition of fibrotic tissue. Biomarkers may play a pivotal role as indicators of disease presence, progression, and treatment response. Sirtuins, a family of enzymes with ADP ribosyltransferase or deacetylase activity, have been implicated in several diseases, including pulmonary fibrosis.

Methods

A cross-sectional, prospective, observational single-center study was conducted to investigate the potential role of serum SIRTs levels as biomarkers in patients with IPF. Demographic, clinical, and functional data and serological samples were collected from 34 patients with IPF followed at the Interstital Lung and Rare Diseases Outpatient Clinic of the Vanvitelli Pneumology Clinic, Monaldi Hospital, Naples, Italy and from 19 age-matched controls.

Results

Serum SIRT-1 levels were significantly reduced in IPF patients compared to controls (median IPF 667 [435–858] pg/mL versus controls 925 [794–1173] pg/mL; p < 0.001 ). In contrast, serum SIRT-3 levels were significantly increased in IPF patients compared to controls (median IPF 338 [230–500] pg/mL versus controls 154 [99.8–246] pg/mL; p < 0.001). There were no statistically significant differences in serum SIRT-6 and SIRT-7 levels between IPF and controls. In addition, we found a significant positive correlation between SIRT-1 and lung function parameters such as FEV1% (ϱ=0.417;p = 0.016), FVC% (ϱ=0.449;p = 0.009) and DLCO% (ϱ=0.393;p = 0.024), while a significant negative correlation was demonstrated between SIR-1 and GAP score, demonstrating a significant reduction in SIRT-1 in advanced Gender-Age-Physiology (GAP) stages 2–3 compared to GAP stage 1 (p = 0.008).

Conclusions

This prospective, cross-sectional study showed that SIRT-1 was associated with lung function and IPF severity and that both SIRT-1 and SIRT-3 could be considered as potential biomarkers of IPF, whereas SIRT-6 and SIRT-7 were not associated with IPF.

Repetitive bouts of coughing expose the large airways to significant cycles of shear stress. This leads to the release of alarmins and the tussive agent adenosine triphosphate (ATP) which may be modulated by the activity of ion channels present in the human airway. This study aimed to investigate the role of the transient receptor potential subfamily vanilloid member 2 (TRPV2) channel in mechanically induced ATP release from primary bronchial epithelial cells (PBECs).

PBECs were obtained from individuals undergoing bronchoscopy. They were cultured in vitro and exposed to mechanical stress in the form of compressive and fluid shear stress (CFSS) or fluid shear stress (FSS) alone at various intensities. ATP release was measured using a luciferin–luciferase assay. Functional TRPV2 protein expression in human PBECs was investigated by confocal calcium imaging. The role of TRPV2 inhibition on FSS-induced ATP release was investigated using the TRPV2 inhibitor tranilast or siRNA knockdown of TRPV2. TRPV2 protein expression in human lung tissue was also determined by immunohistochemistry.

ATP release was significantly increased in PBECs subjected to CFSS compared with control (unstimulated) PBECs (N = 3, ***P < 0.001). PBECs expressed functional TRPV2 channels. TRPV2 protein was also detected in fixed human lung tissue. ATP release from FFS stimulated PBECs was decreased by the TRPV2 inhibitor tranilast (N = 3, **P < 0.01) (vehicle: 159 ± 17.49 nM, tranilast: 25.08 ± 5.1 nM) or by TRPV2 siRNA knockdown (N = 3, *P < 0.05) (vehicle: 197 ± 24.52 nM, siRNA: 119 ± 26.85 nM).

In conclusion, TRPV2 is expressed in the human airway and modulates ATP release from mechanically stimulated PBECs.
