ABSTRACT

The emerging issue of carbon dioxide (CO₂) emissions is highly affecting global sustainable and economic development endeavors. Countries with high population growth, rapid industrialization, and significant energy needs find themselves in this bracket. This study, based on data from 1960 to 2018, evaluates carbon emissions using principal component analysis (PCA). The findings indicate that two leading principal components (C.1 and C.2) had the greatest impact as they accounted for seventy-seven percent (77%) of the total variance. The eigenvalues of both components were greater than one, signifying their significance. C.1 shows a strong connection for CO₂ emissions, total population, and production of electric energy through various sources. C.2 is more connected to the growth of industries. The scree plot confirms this by finding them to be dominant. This emphasizes the interaction between electricity production, specifically from coal, and the demographic data. The results highlight how PCA can be utilized to distinguish drivers that cause the emission of carbon to provide an understanding that might be used in managing the environment and setting relevant policies.

ABSTRACT

OBJECTIVES: To evaluate the effect of androgens on retinal microvasculature in prepubertal girls with isolated premature pubarche (PP) with optical coherence tomography (OCT) and OCT angiography (OCTA).

METHODS: Eighty-six prepubertal, non-obese girls with isolated PP with normal birth weight and 86 age-matched control girls were evaluated. Retinal microvascular structures in the macular and optic disc regions were examined using OCT and OCTA. Data from subjects with isolated PP were compared with data from healthy controls. Correlations between dehydroepiandrosterone sulfate (DHEA-S), androstenedione (AS), testosterone, 17-hydroxyprogesterone (17-OHP) levels, bone age, pubertal stage as well as OCT and OCTA parameters were evaluated.

RESULTS: The inferior retinal nerve fiber layer (RNFL) thickness in the isolated PP group was significantly higher than the control group (p=0.007). A statistically significant increase in the vessel density (VD) was observed in temporal quadrant of the superficial capillary plexus (SCP) and inferior quadrant of the deep capillary plexus (DCP) in the isolated PP group compared with the control group (p<0.05). There were significant positive correlations between DHEAS, AS, testosterone levels and RNFL, macula-disk regions’s OCTA parameters (p<0.05).

CONCLUSIONS: In the isolated PP patients, thickening of RNFL and increased VD in the macula and optic disc region were recognized under the effect of androgens compared to the control group. In these patients, early microvascular changes can be detected noninvasively by means of OCT and OCTA. These findings suggest a potential link between androgen exposure and retinal microvascular alterations; however, further studies are needed to explore their clinical implications.

ABSTRACT

INTRODUCTION: Steatotic liver disease (SLD) and liver fibrosis are significant comorbidities in people living with HIV (PLHIV). Early detection is essential for effective management. This study evaluated the utility of the Fatty Liver Index (FLI) in detecting hepatic steatosis (HS) using Controlled Attenuation Parameter (CAP) measurements as the reference.

METHODS: This cross-sectional study included 446 PLHIV recruited from Cairo University Hospitals. HS was defined as CAP values exceeding 248 dB/m. FLI cut-off points were determined using the Youden index with bootstrapping validation. Performance metrics and kappa concordance statistics were calculated.

RESULTS: The study cohort (78.7% male, median age 35) showed HS in 27.1% (n = 121) and significant liver fibrosis in 6.5% (n = 29). Optimal FLI cut-off of 45 yielded 71% sensitivity and 72% specificity (receiver operating characteristic = 0.77), while the 60 cut-off provided 57% sensitivity and 80% specificity. Despite similar overall prevalence estimates between methods (30.3% by FLI vs. 27.1% by CAP), significant discordance existed (P < 0.001) with only low-moderate agreement (73.5% agreement, κ = 0.465). Nearly half (49%) of participants with CAP-defined HS were misclassified as having no SLD when using FLI. Importantly, HS was associated with significant liver fibrosis when identified by CAP (P < 0.05) but not when identified by FLI (κ = 0.078, P > 0.05).

CONCLUSION: FLI demonstrates substantial limitations as a screening tool for HS in people living with HIV, missing nearly half of CAP-defined cases. The poor concordance with CAP and particularly weak performance in lean individuals-who represent a significant proportion of PWH-indicate that FLI cannot reliably identify HS in this population and should not be used as a standalone diagnostic tool.

ABSTRACT

OBJECTIVE: Providing care for children with life-limiting conditions(LLCs) is an emotionally challenging experience that often exposes caregivers, particularly mothers, to considerable risk of psychological distress. The purpose of this study was to examine the moderating effect of emotional dysregulation on the relationship between severity of anxiety and depressive symptoms and high caregiving intensity, controlling for sociodemographic characteristics among mothers caring for children diagnosed with life-limiting conditions.

METHOD: Using a cross-sectional descriptive design, a convenience sample of 192 mothers caring for children with life-limiting conditions was recruited and filled out an online self-administered questionnaire. Data were collected using online self-administered questionnaires regarding the sociodemographic characteristics of mothers and their children, emotional regulation difficulties (DERS), and the levels of anxiety and depressive symptoms among the mothers (DASS-21).

RESULTS: The analysis showed that 21.4% and 7.8% of mothers had moderate and severe depressive symptoms, and 19.3% and 15.6% had moderate and severe anxiety symptoms, respectively. The analysis also showed that emotional dysregulation is associated with high levels of anxiety (β = 0.74, P < 0.001) and depression (β = 0.74, P < 0.001); however, there was no significant moderating effect.

SIGNIFICANCE OF RESULTS: Anxiety and depression are significant psychological distress among mothers caring for children with life-limiting conditions and can be aggravated by emotional dysregulation and caregiving burden. There is a need to integrate interdisciplinary teamwork and family-centered care to provide holistic care and offer early screening, detection, and emotional regulation-focused management programs for psychological distress at healthcare services that care for children with LLCs.

ABSTRACT

OBJECTIVE: Hospices represent the cornerstone of modern palliative services. However, population-level data on hospice utilization and characteristics of patients dying in hospice remain limited to examine national temporal trends in hospice deaths in Italy from 2011 to 2022, with a focus on the underlying causes of death.

METHODS: We performed a nationwide, population-based retrospective study using official mortality data from the Italian National Institute of Statistics. All deaths registered in Italy between 2011 and 2022 were included. Hospice deaths were identified as those occurring in licensed hospice facilities.

RESULTS: Hospice beds increased from 1,681 in 2011 to 3,419 in 2022, while hospice deaths more than doubled from 19,179 (3.2% of all deaths) to 43,972 (6.2%). The mean age of hospice deaths rose from 74.0 to 76.6 years. Among patients dying in hospice, neoplasms remained the leading cause of death but declined from 87.0% in 2011 to 73.8% in 2022, while cardiovascular deaths increased from 6.2% to 9.5%, neurological from 1.2% to 3.4%, and respiratory from 1.0% to 2.5%. The proportion of national neoplasm deaths occurring in hospice reached approximately 20% in 2022. Similarly, the proportion of non-neoplasm hospice deaths tripled (0.6-2.1%).

SIGNIFICANCE OF THE RESULTS: Between 2011 and 2022, hospice deaths in Italy more than doubled, reflecting substantial progress in expanding access to palliative care. The gradual increase in non-neoplasm hospice deaths suggests a shift toward greater inclusivity, although neoplasm remains predominant.

ABSTRACT

OBJECTIVES: Medical assistance in dying (MAID) is a rapidly growing and evolving field. The provision of MAID in Canada has substantially outpaced the number of new providers. While challenges of provision have been well described, little is known about the sustainability of providing this care long term. To fill this gap, we aimed to determine if providing MAID is sustainable while identifying factors that impact provider wellbeing.

METHODS: We developed a 20-item Likert scale-based questionnaire that focused on themes of sustainability. We performed descriptive analyses for each question and used Fisher’s exact and Kruskal-Wallis tests to assess differences across provider characteristics. The questionnaire was distributed via a network of MAID navigators and providers in Ontario, Canada.

RESULTS: In total, 38 responses were received from well-experienced clinicians in a variety of specialties. A total of 74% of respondents felt their MAID work was sustainable for the long term. Practitioners strongly enjoyed the work and reported little emotional toll and burnout. While some providers felt the compensation and training were sufficient, others felt it could be improved. Nearly all respondents had someone ethically and clinically knowledgeable about MAID they could go to for support.

SIGNIFICANCE OF RESULTS: Our questionnaire has shown clinicians who are well-experienced and connected to supports report very positive experiences providing MAID and view the work as sustainable. While existing literature and media often emphasize the challenges of MAID, the perspectives of providers highlight a positive experience.

ABSTRACT

This study characterized the clinical distribution and antimicrobial susceptibility of Burkholderia cepacia complex (BCC) isolates in the Shaoxing region. A total of 303 clinical BCC isolates collected from 15 healthcare facilities during 2023 were analyzed using MALDI-TOF MS for identification and VITEK 2 COMPACT for susceptibility testing, following CLSI 2023 guidelines (Clinical and Laboratory Standards Institute, 2023). B. cenocepacia (75.2%), B. multivorans (13.5%), and B. cepacia (6.9%) were the predominant species, while six isolates remained unidentified at the species level. Isolates were recovered primarily from male patients (58.1%), individuals over 65 years (70.0%), and ICU (intensive care unit) patients (59.7%). Respiratory specimens – including sputum, throat swabs, and bronchoalveolar lavage fluid – accounted for the majority of isolates (79.5%), followed by pleural/ascitic fluids and blood (11.9%), and urine (2.3%). B. cenocepacia was more prevalent in male patients (63.6%), whereas B. multivorans and B. cepacia predominantly affected females, accounting for 63.4% and 61.9% of cases, respectively (p = 0.001). Regarding age distribution, the majority of patients across all three species were over 65 years of age, with no statistically significant difference observed among the groups (p = 0.713). Significant associations were also found between species and both hospital setting (p = 0.020) and specimen type (p<0.001). All three major species exhibited high susceptibility (>90%) to ceftazidime, with no significant differences among them. In contrast, statistically significant differences (P<0.05) were observed in the susceptibility rates of B. cenocepacia compared to the other two species toward minocycline, meropenem, levofloxacin, and trimethoprim-sulfamethoxazole. These results highlight the necessity of AST (Antimicrobial Susceptibility Testing)-guided therapy to optimize treatment and limit resistance development.

ABSTRACT

BACKGROUND: Children are a particularly vulnerable population for tuberculosis (TB). The present study aims to describe epidemiological characteristics and temporal trends of paediatric TB in Spain.

METHODOLOGY: A retrospective study of paediatric TB in Spain was conducted using data from the National Epidemiological Surveillance Network and the l Basic Minimum Data Set of Hospitalizations from 2012 to 2023. Trends of annual notification rates (NR), hospitalization rates (HR) and annual percentage of change (APC) were calculated.

RESULTS: Between 2012 and 2023 there were 3,472 reported cases and 2,768 hospitalizations. The mean NR and HR of the period were 4.2 and 3.3 per 100,000 inhabitants, respectively. The NR and the HR decreased from 5.0 to 3.5 and from 5.0 to 2.8, with significant APCs of -5.05 and -7.25, respectively. The most affected age group was 1-4 (39.8% of notifications and 43.4% of hospitalizations). Severe presentations (miliary and meningitis) were more common amongst cases less than 1-year-old.

CONCLUSIONS: A decreasing trend in paediatric TB in Spain has been observed since 2012, with a slight rebound since 2021. Younger children aged 1-4 had the highest incidence while children under 1 year had the highest percentage of severe TB. This highlights the importance of prioritizing and strengthening control strategies in this age group.

ABSTRACT

AIMS: To evaluate whether faster insulin aspart (FIA) improves time in range (TIR) compared with standard insulin aspart (SIA) in children and adolescents with type 1 diabetes achieving glycaemia close to target treated with continuous subcutaneous insulin infusion (CSII) and continuous glucose monitoring (CGM).

METHODS: This prospective, open-label, randomized, 1:1 crossover trial included participants aged 6-17 years with T1D duration of ≥1 year, CSII use ≥3 months, CGM use ≥1 month, and HbA1c 64 mmol/mol (<8%). After a 2-week run-in period, they then crossed over to the alternate insulin for another 4 weeks. All participants used the same CGM system. Assessments were performed at the end of each treatment phase. The primary endpoint was the between-treatment difference in TIR (3.9-10.0 mmol/L, 70-180 mg/dL).

RESULTS: Seventy-seven children were enrolled (mean T1D duration approximately 7 years; 66% male; mean HbA1c 53 mmol/mol, 7%). Mean TIR was 68.5% (SD 12.3%) with SIA and 67.6% (SD 12.1%) with FIA, with no statistically significant difference (mean difference -0.9%; 95% CI -2.60 to 0.86; P = 0.322). Similar patterns were observed for additional glycaemic metrics. Time in tight range was also similar between treatments: 46.3% for SIA versus 45.4% for FIA (P = 0.674).

CONCLUSIONS: In this randomised crossover study of children and adolescents with T1D achieving glycaemia close to target on CSII, switching from SIA to FIA does not improve TIR. The absence of improvement across CGM-derived metrics suggests that FIA does not meaningfully enhance glycaemic outcomes in this clinical setting.

ABSTRACT

STUDY QUESTION: Can natural cycles (NC) be effectively utilized in advanced maternal age (AMA) undergoing oocyte donation, without compromising live birth rates (LBRs) and miscarriage outcomes, when compared to artificial cycles (ACs)?

SUMMARY ANSWER: In donor oocyte embryo transfer cycles, NC demonstrated superior outcomes in reproductive efficacy and obstetrical safety compared to AC, independent of the recipient’s age.

WHAT IS KNOWN ALREADY: Previous studies have posited that NC may result in better outcomes when compared to AC embryo transfer, including a lower risk of miscarriage and hypertensive disorders of pregnancy. Recent studies support that NC-frozen embryo transfer (FET) decreases obstetrical and neonatal complications compared to AC-FET, even if LBR differences remain controversial in some general populations. There is limited research on the use of NCs in women of AMA.

STUDY DESIGN, SIZE, DURATION: This retrospective, multicentre, cohort study included all single blastocyst embryo transfers following oocyte donation performed between January 2010 and December 2023, subdivided according to the type of endometrial preparation performed (NC or AC). The oocyte donation model was chosen to minimize the potential confounding effect related to poor oocyte competence in older women and the influence of ovarian stimulation performed during autologous IVF on endometrial receptivity prior to a fresh embryo transfer.

PARTICIPANTS/MATERIALS, SETTING, METHODS: The main objective of the study was to compare LBR. Secondary outcomes included hCG-positive pregnancy rate, clinical pregnancy rate, miscarriage rate, obstetric, and perinatal outcomes. Confounder-adjustment was performed using a multivariable generalized estimating equations model regression analysis, adjusting for multiple confounders. A sub-analysis compared results when the AC protocol was optimized with progesterone (P4) monitoring and rescue therapy. Additionally, an interaction variable was added to the final multivariable model to assess whether female recipient age may modify the effect of each type of endometrial preparation on LBRs.

MAIN RESULTS AND THE ROLE OF CHANCE: In total, 67 048 embryo transfers were analysed, including NC (n = 6922) and AC (n = 60 126). The NC group demonstrated consistent superiority over AC after adjustment for confounders across all transfers. NC was associated with a higher LBR (aOR 1.38, 95% CI 1.29-1.47; P < 0.01) and significantly lower miscarriage rate per hCG-positive pregnancy (aOR 0.68, 95% CI 0.61-0.76; P < 0.01). This superiority persisted even in optimized AC cycles with P4 monitoring and rescue therapy (LBR aOR 1.42, 95% CI 1.31-1.54; P < 0.01). Furthermore, NC was associated with significantly lower obstetrical risks in singleton pregnancies, including hypertensive disorders of pregnancy (aOR 0.72, 95% CI 0.56-0.94; P = 0.01), Caesarean delivery (aOR 0.86, 95% CI 0.77-0.96; P < 0.01), and large for gestational age (aOR 0.77, 95% CI 0.67-0.89; P < 0.01). The interaction between endometrial preparation method and female recipient age was not statistically significant (aOR 1.02, 95% CI 0.99-1.03).

LIMITATIONS, REASONS FOR CAUTION: The retrospective nature of the study and the inherent risk of bias related to unmeasured confounding factors may have impacted the results. Another limitation is the low percentage of NC included in the study (10.32% of all cycles), which could be related to the low uptake to this treatment modality in real-life practice.

WIDER IMPLICATIONS OF THE FINDINGS: NC may offer superior reproductive outcomes and is associated with lower obstetrical risks, with differences unlikely to be modified by female age. Therefore, it seems reasonable to suggest NC for older women, as they could benefit from the decreased risk of miscarriage and hypertension during pregnancy.
