Abstract
Background
Bacterial spot of pepper (BSP), caused by four different Xanthomonas species, primarily X. euvesicatoria (Xe), poses a significant challenge in pepper cultivation. Host resistance is considered the most important approach for BSP control, offering long-term protection and sustainability. While breeding for resistance to BSP for many years focused on dominant R genes, introgression of recessive resistance has been a more recent focus of breeding programs. The molecular interactions underlying recessive resistance remain poorly understood.

Results
In this study, transcriptomic analyses were performed to elucidate defense responses triggered by Xe race P6 infection by two distinct pepper lines: the Xe-resistant line ECW50R containing bs5, a recessive resistance gene that confers resistance to all pepper Xe races, and the Xe-susceptible line ECW. The results revealed a total of 3357 upregulated and 4091 downregulated genes at 0, 1, 2, and 4 days post-inoculation (dpi), with the highest number of differentially expressed genes (DEGs) observed at 2 dpi. Pathway analysis highlighted DEGs in key pathways such as plant-pathogen interaction, MAPK signaling pathway, plant hormone signal transduction, and photosynthesis – antenna proteins, along with cysteine and methionine metabolism. Notably, upregulation of genes associated with PAMP-Triggered Immunity (PTI) was observed, including components like FLS2, Ca-dependent pathways, Rboh, and reactive oxygen species (ROS) generation. In support of these results, infiltration of ECW50R leaves with bacterial suspension of Xe led to observable hydrogen peroxide accumulation without a rapid increase in electrolyte leakage, suggestive of the absence of Effector-Triggered Immunity (ETI). Furthermore, the study confirmed that bs5 does not disrupt the effector delivery system, as evidenced by incompatible interactions between avirulence genes and their corresponding dominant resistant genes in the bs5 background.

Conclusion
Overall, these findings provide insights into the molecular mechanisms underlying bs5-mediated resistance in pepper against Xe and suggest a robust defense mechanism in ECW50R, primarily mediated through PTI. Given that bs5 provides early strong response for resistance, combining this resistance with other dominant resistance genes will enhance the durability of resistance to BSP.

Abstract
Background
Phosphorus (P) deficiency, a major nutrient stress, greatly hinders plant growth. Phosphate (Pi) uptake in plant roots relies on PHT1 family transporters. However, melon (Cucumis melo L.) lacks comprehensive identification and characterization of PHT1 genes, particularly their response patterns under diverse stresses.

Results
This study identified and analyzed seven putative CmPHT1 genes on chromosomes 3, 4, 5, 6, and 7 using the melon genome. Phylogenetic analysis revealed shared motifs, domain compositions, and evolutionary relationships among genes with close histories. Exon number varied from 1 to 3. Collinearity analysis suggested segmental and tandem duplications as the primary mechanisms for CmPHT1 gene family expansion. CmPHT1;4 and CmPHT1;5 emerged as a tandemly duplicated pair. Analysis of cis-elements in CmPHT1 promoters identified 14 functional categories, including putative PHR1-binding sites (P1BS) in CmPHT1;4, CmPHT1;6, and CmPHT1;7. We identified that three WRKY transcription factors regulated CmPHT1;5 expression by binding to its W-box element. Notably, CmPHT1 promoters harbored cis-elements responsive to hormones and abiotic factors. Different stresses regulated CmPHT1 expression differently, suggesting that the adjusted expression patterns might contribute to plant adaptation.

Conclusions
This study unveils the characteristics, evolutionary diversity, and stress responsiveness of CmPHT1 genes in melon. These findings lay the foundation for in-depth investigations into their functional mechanisms in Cucurbitaceae crops.

Published: July 2024

Abstract
Background
Intravenous lidocaine has shown promise as an effective analgesic in various clinical settings, but its utility for pain management in emergency departments, especially for bone fractures, remains relatively understudied.

Objective
This study compared intravenous lidocaine to pethidine for femoral bone fracture pain management.

Methods
This double-blind, randomized, controlled clinical trial was conducted in the emergency department of AJA University of Medical Sciences affiliated hospitals. Patients aged 18–70 years-old with femoral bone fracture and experiencing severe pain, defined as a numerical rating scale (NRS) of pain ≥ 7, were included in the study. One group received intravenous pethidine (25 mg), while the other group received intravenous lidocaine (3 mg/kg, not exceeding 200 mg), infused with 250 ml saline over 20 min. Pain levels were evaluated before treatment administration (0 min) and at 10, 20, 30, 40, 50, and 60 min after treatment administration using the NRS.

Results
Seventy-two patients were enrolled in the study. Demographic characteristics and pain scores were similar between the two groups. The mean pain scores upon arrival for the lidocaine and pethidine groups were 8.50 ± 1 and 8.0 ± 1, respectively; after one hour, they were 4.0 ± 1 and 4.0 ± 1, respectively. While there was a statistically significant reduction in pain in both groups after one hour, there were no clinically or statistically significant differences between the two groups (p = 0.262). Pethidine had a higher incidence of adverse events, though not statistically significant. Additionally, females required more rescue analgesics.

Conclusion
The administration of intravenous lidocaine is beneficial for managing pain in femoral bone fractures, suggesting that lidocaine could be a potent alternative to opioids.

REEP5 mediates the function of CLEC5A to alleviate myocardial infarction by inhibiting endoplasmic reticulum stress-induced apoptosis
Authors: Wang Xin , Sun Limin 
Published: July 2024

AbstractMI (myocardial infarction) often triggers severe heart failure and is one of the leading causes of death worldwide. Receptor expression-enhancing protein 5 (REEP5), a member of REEPs, acts as regulators of endoplasmic reticulum (ER) affecting cardiac functions. Based on GSE114695 profile data, REEP5 was decreased in the left ventricle of MI mice. However, its role and potential mechanism in MI remain to be investigated. In the present study, the mouse MI model was established by ligation of the left anterior descending artery. REEP5 expression was downregulated in the infarct penumbra area of MI mice. Next, its role during MI was explored by gain-of-function. Interestingly, REEP5 overexpression improved left ventricular function of mice with MI, accompanied with reduced infarct size. In cardiomyocytes, REEP5 overexpression inhibited ER stress, accompanied with repressive phosphorylation of PERK and IRE1α, and the decreased nuclear translocation of ATF6. Subsequently, REEP5 overexpression downregulated the levels of Chop and cleaved caspase-12, further alleviating ER stress-induced apoptosis, which was consistent with the in vivo results. Moreover, REEP5 was found to bind to C-type lectin member 5 A (CLEC5A), a protein that triggers cardiac dysfunction. CLEC5A, whose expression was elevated in hypoxia-induced cell models, led to cardiomyocyte apoptosis. Noteworthily, REEP5 overexpression markedly abolished the effects of CLEC5A on ER stress-induced apoptosis. Taken together, REEP5 mediated the function of CLEC5A to relieve MI via inhibiting ER stress-induced apoptosis in vivo and in vitro. REEP5 may be a promising target for treating MI.
The relationship between the systemic immune inflammation index and the nonalcoholic fatty liver disease in American adolescents
Authors: Fu Dong-fang , Chen Bin 
Published: July 2024

Abstract
Background
Non-alcoholic fatty liver disease (NAFLD) is a growing health crisis in the general population of the United States (U.S.), but the relationship between systemic immune-inflammation (SII) index and NAFLD is not known.

Methods
We collected data from the National Health and Nutrition Examination Survey 2017–2018. Next, propensity score matching (PSM), collinearity analysis, restricted cubic spline (RCS) plot, logistic regression, quantile regression analysis, subgroup analysis, mediation analysis, and population attributable fraction were used to explore the association of the SII with risk of NAFLD.

Results
A total of 665 participants including the 532 Non-NAFLD and 133 NAFLD were enrolled for further analysis after PSM analysis. The RCS results indicated that there was a linear relationship between the SII and controlled attenuation parameter (p for nonlinear = 0.468), the relationship also existed after adjustment for covariates (p for nonlinear = 0.769). The logistic regression results indicated that a high SII level was an independent risk factor for NAFLD (OR = 3.505, 95% CI: 1.092–11.249, P < 0.05). The quantile regression indicated that at higher quantiles (0.90, and 0.95) the SII was significantly associated with NAFLD (p < 0.05). Mediation analysis indicated that alanine aminotransferase (ALT), triglycerides, and blood urea nitrogen (BUN) were partially contribute to the relationship between SII and NAFLD. The population attributable fractions indicated that 23.19% (95% CI: 8.22%, 38.17%) of NAFLD cases could be attributed to SII corresponding to 133 NAFLD cases.

Conclusion
There was a positive linear relationship between the SII and the risk of NAFLD. The ALT, triglycerides, and BUN had a partial mediating effect on the relationship between the SII and NAFLD.

Published: July 2024

Abstract
Background
In the pivotal phase III RECOURSE trial, trifluridine/tipiracil (FTD/TPI) improved progression-free and overall survival (PFS, OS) of patients with pre-treated metastatic colorectal cancer (mCRC). Subsequently, the TALLISUR trial provided post-authorisation efficacy and safety data and patient-reported outcomes on quality of life (QoL) in a German patient cohort. The present analysis reports the final data on efficacy, safety and QoL and investigates the impact of baseline characteristics and associated prognostic subgroups on outcome.

Methods
In this prospective, multi-centre, Germany-wide, phase IV study, patients with pre-treated mCRC were given the choice to receive either FTD/TPI or best supportive care (BSC). To assess the primary endpoint, QoL, EORTC QLQ-C30 questionnaires were employed. Secondary endpoints included QoL assessed through EQ-5D-5L questionnaires, OS, PFS and safety. Additionally, 3 subgroups were defined according to a post-hoc analysis of the RECOURSE trial: best, good and poor prognostic characteristics (BPC, GPC, PPC). Patients with < 3 metastatic sites at inclusion and/or ≥ 18 months from diagnosis to inclusion were considered to have GPC. GPC patients without liver metastasis at inclusion were considered to have BPC. All remaining patients were considered to have PPC.

Results
Of 195 patients, 186 decided to receive FTD/TPI and 9 to receive BSC. The low number of patients in the BSC-arm did not allow statistically meaningful analyses. Treatment with FTD/TPI was associated with maintained QoL. For all patients, median OS was 6.9 months (95% CI 6.1 – 8.3) and for the defined subgroups (BPC n = 20 vs GPC n = 65 vs PPC n = 121) 12.2, 7.9 and 6.8 months (95% CI 6.0 – 18.2, 6.2 – 13.3, 5.4 – 8.1). The most frequent TEAEs were neutropenia (29.6%), anaemia (24.7%) and nausea (23.7%). Febrile neutropenia occurred in 1.1%.

Conclusions
Treatment of patients suffering from pre-treated mCRC with FTD/TPI was associated not only with prolonged survival and delayed progression, but also with maintained QoL. Independent of other baseline characteristics such as ECOG performance status and age, low metastatic burden and indolent disease were factors associated with favourable outcome.

Dynamics of postnatal depressive symptoms in early parenthood
Authors: Skjerdingstad Nora , Speyer Lydia G. , Isvoranu Adela-Maria , Moe Vibeke , Fredriksen Eivor 
Published: July 2024

Abstract
Background
New mothers and fathers are at risk of developing postnatal depressive problems. To understand how postnatal depressive symptoms unfold over time, analyses at the within-person level are necessary. Inspecting postnatal depressive problems at the symptom level provides a novel perspective, ultimately offering insight into which symptoms contribute to the elevation of other symptoms over time.

Methods
Panel graphical vector-autoregression (GVAR) models were applied to analyze the within-person temporal and contemporaneous relations between depressive symptoms across the postnatal period in new mothers and fathers (at T1; Nmothers = 869, Nfathers = 579). Depressive symptoms were assessed at 6-, 12-, and 18-months postpartum, using the Edinburgh Postnatal Depression Scale.

Results
The results revealed that for mothers, sadness was a key symptom predicting symptom increases in multiple other depressive symptoms and itself (autoregressive effect) over time. Furthermore, anxiousness and feeling scared predicted each other across the postnatal period in mothers. For fathers, the most central predicting symptom in the overall network of symptoms was being anxious, while self-blame and being overwhelmed had strong self-maintaining roles in the fathers’ symptomatology, indicating that these could be key features in fathers experiencing postnatal depressive problems. The pattern of symptoms that mothers and fathers experienced within the same time window (contemporaneous associations), shared many of the same characteristics compared to the temporal structure.

Conclusions
This study suggests that across the postnatal period, from 6- to 18-months postpartum, depressive symptoms in mothers and fathers contribute differently to the pattern of depressive problems, highlighting sadness as a key feature in maternal symptomatology and anxiousness components in paternal symptomatology.

Published: July 2024

Abstract
Objectives
This study aimed to investigate the association of cystatin C, serum creatinine and sarcopenia index with cardiovascular and all-cause death in general population.

Methods
Data of participants from the National Health and Nutrition Examination Surveys (NHANES) from 1999 to 2004 were used and all participants were followed up regularly until December 31, 2019. Multivariable Cox analysis was used to investigate the association of cystatin C, serum creatinine and sarcopenia index with cardiovascular and all-cause death. Restricted cubic spline was conducted to evaluate the nonlinear association.

Results
A total of 9894 participants with a mean age of 45.64 years were enrolled and followed up for a mean duration of 15.62 ± 4.68 years. Approximately 50.3% were male and there were a total of 2681 all-cause deaths and 691 cardiovascular deaths recorded during the follow-up period. In final adjusted model, compared with the first quartile of cystatin C (< 0.659 mg/L), the risk of cardiovascular and all-cause death increased 2.36-fold and 1.71-fold for participants in the fourth quartile (≥ 0.877 mg/L) (HR: 3.36, 95% CI: 2.06–5.46, P < 0.001; HR: 2.71, 95% CI: 2.17–3.38, P < 0.001; respectively). Furthermore, a higher sarcopenia index (< 88.41 vs. ≥125.52) was associated with the reduced risk of cardiovascular death (HR: 0.41, 95% CI: 0.31–0.53, P < 0.001) as well as all-cause death (HR: 0.41, 95% CI: 0.35–0.49, P < 0.001). Additionally, restricted cubic splines showed that there was a nonlinear relationship between sarcopenia index levels and all-cause death while there was a linear relationship between sarcopenia index levels and cardiovascular death.

Conclusions
Higher sarcopenia index was associated with the decreased risk of cardiovascular and all-cause death in general population in the United States. Elevated cystatin C was positively associated with cardiovascular and all-cause death.

Published: July 2024

Abstract
Background
Dentigerous cysts, deemed of developmental origin, are benign odontogenic cysts characterized by a gradual growth rate. Their occurrence is twice as prevalent in men compared to women. These cysts are recognized as the most frequent developmental cysts affecting the jaws, with a typical manifestation in individuals aged 20 to 40, while infrequently identified in young children. Notably, dentigerous cysts have the potential to attain significant dimensions, resulting in painless enlargement of the jaw and subsequent deformation.

Objectives
To assess the clinicopathological features and management of ten years of experience with dentigerous cysts.

Methods
A challenging cases were reported from reviewed records of the patients who were treated by the surgical intervention of various dentigerous cysts throughout the period of ten years, 2012–2022 and only histologically confirmed cases were selected, at Ramadi Teaching Hospital in addition to Rashid, Razi, Zuhur Private Hospitals and private clinics in Iraq.

Results
76 patients were included in this clinicopathological research. The highest age group affected was ≤ 18 years (68.4%), 54% were male, the mandible was more affected (63.1%) than the maxilla (36.9%). Marsupialization was applied to 30.3% of the cases, while enucleation was carried out in 69.7%.

Conclusions
The significance of meticulous examination of radiographs and the consequences associated with undetected and untreated ailments is affirmed by this case study. A comprehensive understanding of oral pathology serves as a valuable resource for dentists, facilitating accurate diagnosis, appropriate referrals, and the provision of anticipatory guidance to patients striving to achieve optimal oral health across various age groups.

Abstract
Background
Despite attempts to increase Universal Health Coverage, availability, accessibility, acceptability, and quality-related challenges remain barriers to receiving essential services by women who need them. We aimed to explore the experiences and perceptions of women receiving post-abortal care services in Zambia, within a human-rights framework.

Methods
A qualitative case study was conducted between August and September 2021 in Lusaka and Copperbelt provinces of Zambia. Fifteen (15) women seeking post-abortion care services were` interviewed using audio recorders; transcribed data was analyzed using thematic analysis. We report women’s experiences and perceptions of the healthcare system, their experiences of abortion, and healthcare-seeking behaviour. We used the availability, accessibility, acceptability, and quality (AAAQ) framework to understand how women claimed their right to healthcare as they sought and utilized post-abortion care services.

Results
Women who experienced spontaneous abortions delayed seeking health care by viewing symptoms as ‘normal pregnancy symptoms’ and not dangerous. Women also delayed seeking care because they feared the negative attitudes from their communities and the health care providers towards abortion in general, despite it being legal in Zambia. Some services were considered costly, impeding their right to access quality care.

Conclusions
Women delayed seeking care compounded by fear of negative attitudes from the community and healthcare providers. To ensure the provision and utilization of quality all abortion-related healthcare services, there is a need to increase awareness of the availability and legality of safe abortion services, the importance of seeking healthcare early for any abortion-related discomfort, and the provision and availability of free services at all levels of care should be emphasized.
