Regulatory elements (enhancers) are major drivers of gene expression in mammals and harbor many genetic variants associated with human diseases. Here, we present an updated VISTA Enhancer Browser (https://enhancer.lbl.gov), a database of transgenic enhancer assays conducted in developing mouse embryos in vivo. Since the original publication in 2007, the database grew nearly 20-fold from 250 to over 4500 experiments and currently harbors over 23 500 images. The updated database provides structured information on experiments conducted at different stages of embryonic development, including enhancer activities of human pathogenic and synthetic variants and sequences derived from a variety of species. In addition to manually curated results of thousands of individual experiments, the new database also features hundreds of manually curated comparisons between alleles. The VISTA Enhancer Browser provides a crucial resource for study of human genetic variation, gene regulation and developmental biology.

Published: October 2024

The emergence of spatial transcriptomic technologies has opened new avenues for investigating gene activities while preserving the spatial context of tissues. Utilizing data generated by such technologies, the identification of spatially variable (SV) genes is an essential step in exploring tissue landscapes and biological processes. Particularly in typical experimental designs, such as case-control or longitudinal studies, identifying SV genes between groups is crucial for discovering significant biomarkers or developing targeted therapies for diseases. However, current methods available for analyzing spatial transcriptomic data are still in their infancy, and none of the existing methods are capable of identifying SV genes between groups. To overcome this challenge, we developed SPADE for spatial pattern and differential expression analysis to identify SV genes in spatial transcriptomic data. SPADE is based on a machine learning model of Gaussian process regression with a gene-specific Gaussian kernel, enabling the detection of SV genes both within and between groups. Through benchmarking against existing methods in extensive simulations and real data analyses, we demonstrated the preferred performance of SPADE in detecting SV genes within and between groups. The SPADE source code and documentation are publicly available at https://github.com/thecailab/SPADE.

Published: October 2024

Brain health is a pressing global concern. Poor diet quality is a recognized major environmental risk factor for brain disorders and one of the few that is modifiable. There is substantial evidence that nutrition impacts brain development and brain health across the life course. So why then is the full potential of nutrition not utilized to improve brain function? This commentary, which is based on discussions of the European Brain Research Area BRAINFOOD cluster, aims to highlight the most urgent research priorities concerning the evidence base in the area of nutrition and brain health and identifies 3 major issues that need to be addressed: (1) increase causal and mechanistic evidence on the link between nutrition and brain health, (2) produce effective messages/education concerning the role of food for brain health, and (3) provide funding to support collaborative working across diverse stakeholders.
Long-term safety of selpercatinib for Rearranged during transfection (RET)-activated advanced solid tumors in LIBRETTO-001: differing patterns of adverse events over time
Authors: Raez Luis E , Massey Ashish C , Barker Scott S , Peterson Patrick M , Liming Katherine , Pennell Nathan A
Published: October 2024

Background

Selpercatinib is a selective RET inhibitor approved for treatment of RET-activated cancers. Adverse events (AEs) are manageable with dose modifications. This post hoc analysis characterized selpercatinib’s clinical safety profile after long-term follow-up in the safety population of LIBRETTO-001.

Patients and Methods

LIBRETTO-001 is an ongoing phase I/II, single-arm, open-label trial (NCT03157128). Eligible patients were ≥18 years old with diagnosis of advanced/metastatic RET fusion-positive solid tumor, RET-mutant medullary thyroid cancer, or other RET-activated tumors. In phase I, patients received selpercatinib 20 mg QD or 20-240 mg BID; patients in phase II received 160 mg BID. The analyzed population comprised all patients who received ≥1 selpercatinib dose and were followed up until data cutoff (January 13, 2023).

Results

For the 837 patients, median follow-up was 45.4 months (95% CI, 44.5-46.6); median time on treatment was 30.1 months (range 0.1-66.8). Grade ≥3 treatment-emergent AEs (TEAEs) were reported in 76.2% of patients; most common events were hypertension (19.7%), ALT increased (11.8%), and hyponatremia (9.2%). Serious TEAEs were reported in 51.4% of patients. Most frequently reported any-grade AEs at <6 months of treatment were fatigue (36.6%), dry mouth (32.8%), and ALT increased (30.5%); at ≥24 months of treatment, these were edema (63.2%), diarrhea (60.7%), and fatigue (53.0%). Selpercatinib-related TEAEs leading to reduced dosage were reported in 39.3%, those leading to treatment interruption were reported in 47.1%, and those leading to discontinuation were reported in 4.3% of patients.

Conclusion

Long-term treatment with selpercatinib is feasible. AEs are manageable with dose modifications, allowing most patients to continue safely on therapy.
Therapeutic targeting of the protein tyrosine kinase-7 in cancer: an overview
Authors: Mottard Kim , Cokaiko Julie , Rogister Bernard , Neirinckx Virginie
Published: October 2024

The protein tyrosine kinase-7 (PTK7) is an evolutionarily conserved transmembrane receptor that has emerged as a potential therapeutic target for human tumors. PTK7 is a pseudokinase that is involved in the modulation of the Wnt signaling pathway through interactions with other receptors. These interactions result in targeted gene activation that regulates cell polarity, migration, and proliferation during embryogenesis. Aside of this role during development, PTK7 has been shown as overexpressed in numerous cancers including colon carcinoma, leukemia, neuroblastoma, hepatoma, and ovarian cancer. The activity of PTK7 and the direct correlation with poor prognosis have fostered preclinical investigations and phase I clinical trials, aiming at inhibiting PTK7 and inducing antitumoral effects. In this review, we provide an exhaustive overview of the diverse approaches that use PTK7 as a new molecular target for cancer therapy in different tumor types. We discuss current therapies and future strategies including chimeric antigen receptor-T cells, antibody-drug conjugates, aptamers, based on up-to-date literature and ongoing research progress.

Authors: Huang Richard S P , Lee Jessica K , Lofgren Katherine T
Published: October 2024

The use of biomarker testing to inform treatment decisions has emerged as a standard of care in multiple cancer types. However, the rates of patients with genomic testing results in hand to inform treatment decision-making remain variable. Here, we studied the impact of comprehensive genomic profiling (CGP) on clinical trial enrollment rates in patients with advanced-stage non-small cell lung, colorectal, breast, and prostate cancer using a real-world clinicogenomic database. On average, clinical trial enrollment in the therapy line immediately after CGP report receipt was 5.4%, which represents a 3.0 percentage point increase compared to therapy lines preceding CGP report receipt, supporting a meaningful association between CGP report availability and increased clinical trial enrollment.
House Prices and Rents
Authors: Fama Eugene F , French Kenneth R
Published: October 2024

Variation in monthly metro area house prices unrelated to expected rents clouds the information about future rents in price-rent ratios and lagged changes in house prices. The variation in house prices unrelated to expected rents is, however, correlated across areas, and the problem is mitigated by measuring rent growth regression variables net of their monthly cross-section (across-area) means. This control for price variation unrelated to expected rents substantially enhances the information about future rents that we extract from price-rent ratios and lagged changes in house prices.

Published: October 2024

Background

It is known that impairments in linguistic ability and motor function tend to co-occur in children, and that children from families with parental mental illness such as schizophrenia tend to perform poorly in both domains, but the exact nature of these links has not yet been fully elucidated.

Design

In this study, we leveraged the first wave of the Danish High Risk and Resilience Study (VIA 7), which includes both genetic data and measures covering multiple developmental domains. The VIA 7 cohort comprises 522 7-year-old children born to parents with schizophrenia (N = 202), bipolar disorder (N = 120) or neither (N = 200). We investigated the relationships between linguistic ability and motor function using correlation and regression analyses, focusing on developmental coordination disorder (DCD) and specific language impairment (SLI) and their potential associations with the three risk groups.

Results

We found significant correlations between most measures of language and motor function and significant associations of DCD and SLI with language and movement measures, respectively, the largest effect being that of DCD on receptive language, with a significant interaction effect: DCD was associated with poorer performance in children from schizophrenia families compared to bipolar disorder and control families. Both disorders showed higher prevalence among children with familial high risk of mental illness. We did not find significant evidence of genetic overlap between DCD and SLI.

Conclusions

Our results suggest strong links between the domains of motor function and linguistic ability. Children of parents with schizophrenia are at high risk of comorbid language and movement disorders.

Published: October 2024

We aimed to test the association between sleep-related polygenic scores (PGSs) and accelerometer-based sleep metrics among Brazilian adolescents and to evaluate potential mechanisms underlying the association through the enrichment of obesity, and cortisol pathway-specific polygenic scores (PRSet). Utilizing data from The 2004 Pelotas (Brazil) Birth Cohort, sleep time window and sleep efficiency were measured at the 11-year-old follow-up using ActiGraph accelerometers. Three sleep PGSs were developed based on the most recent genome-wide association study of accelerometer-based sleep measures. PRSet, calculated using variants linked to body mass index (BMI) and plasmatic cortisol concentration, aimed to assess pleiotropic effects. Linear regression models, adjusted for sex and the first 10 principal components of ancestry, were employed to explore the impact of sleep PGS and specific-PRSet on sleep phenotypes. The number of nocturnal sleep episodes-PGS was positively associated with sleep time window (β = 2.306, SE: 0.92, p = .011). Nocturnal sleep episodes were also associated with sleep time window when restricted to BMI-PRSet (β = 2.682, SE: 0.912, competitive p = .003). Both the number of sleep episodes and sleep time window cortisol-PRSets were associated (β = .002, SE: 0.001, p = .013; β = .003, SE: 0.001, p = .003, respectively) and exhibited enrichment in molecular pathways (competitive p = .011; competitive p = .003, respectively) with sleep efficiency. Sleep polygenetic components observed in European adults may partially explain the accelerometer-based sleep time window in Brazilian adolescents. Specific BMI molecular pathways strengthened the association between sleep PGS and sleep time window, while the cortisol concentration pathway had a significant impact on the genetic liability for sleep efficiency. Our results suggest genetic overlap as a potential etiological pathway for sleep-related comorbidities, emphasizing common genetic mechanisms.
Outcomes of patients with acute liver failure not listed for liver transplantation: A cohort analysis
Authors: Dong Victor , Durkalski Valerie , Lee William M. , Karvellas Constantine J. ,   and the United States Acute Liver Failure Study Group
Published: October 2024

Background:

Acute liver failure (ALF) is a rare condition leading to morbidity and mortality. Liver transplantation (LT) is often required, but patients are not always listed for LT. There is a lack of data regarding outcomes in these patients. Our aim is to describe outcomes of patients with ALF not listed for LT and to compare this with those listed for LT.

Methods:

Retrospective analysis of all nonlisted patients with ALF enrolled in the Acute Liver Failure Study Group (ALFSG) registry between 1998 and 2018. The primary outcome was 21-day mortality. Multivariable logistic regression was done to identify factors associated with 21-day mortality. The comparison was then made with patients with ALF listed for LT.

Results:

A total of 1672 patients with ALF were not listed for LT. The median age was 41 (IQR: 30–54). Three hundred seventy-one (28.9%) patients were too sick to list. The most common etiology was acetaminophen toxicity (54.8%). Five hundred fifty-eight (35.7%) patients died at 21 days. After adjusting for relevant covariates, King’s College Criteria (adjusted odds ratio: 3.17, CI 2.23–4.51), mechanical ventilation (adjusted odds ratio: 1.53, CI: 1.01–2.33), and vasopressors (adjusted odds ratio: 2.10, CI: 1.43–3.08) (p < 0.05 for all) were independently associated with 21-day mortality. Compared to listed patients, nonlisted patients had higher mortality (35.7% vs. 24.3%). Patients deemed not sick enough had greater than 95% survival, while those deemed too sick still had >30% survival.

Conclusions:

Despite no LT, the majority of patients were alive at 21 days. Survival was lower in nonlisted patients. Clinicians are more accurate in deeming patients not sick enough to require LT as opposed to deeming patients too sick to survive.

Authors: Junior Obinwanne Chukwuemeka , Barrah Sharon , Kobia-Acquah Emmanuel , Titiati Perfect Emefa , Karikari Lucy Akua Afriyie , Akowuah Prince
Published: October 2024

Objectives:

To investigate the referral and management patterns of patients with keratoconus among primary eye care practitioners in Ghana and Nigeria.

Methods:

A questionnaire adapted from previous studies was modified and created using Google Forms. The online survey was distributed to prospective participants using e-mails and other social media platforms. Data were analyzed using the Statistical Product and Service Solutions software (version 25.0; IBM Corp, Armonk, NY; Released 2017).

Results:

One hundred and sixty-nine optometrists responded to the survey (61.54% from Nigeria and 38.46% from Ghana). Most (88.6%) practiced without corneal topographers. Most respondents (77.7%, n=136) reported not fitting rigid gas-permeable (RGP) contact lenses in a year and 68% were willing to refer for contact lens fitting to another practitioner. The major barriers to RGP fitting were lack of experience (44.4%, n=72), cost to practice (15.4%, n=25), and other reasons (12.4%), whereas 27.8% (n=45) preferred not to answer. Seventy-six percent of respondents (n=133) were willing to fit RGPs if the respondents received the training to do so. About half of the respondents (53.8%) reported progression of cornea signs as the reason for referral to an ophthalmologist. Half of the respondents (n=51.4%) did not have a cornea surgeon in the area the respondents practiced, and 76.3% reported not comanaging patients at all with ophthalmologists.

Conclusion:

This study highlights the current standard of care of patients with keratoconus in West Africa. The findings from this study suggest that clinical guidelines and further training of eye care practitioners in West Africa are needed to better manage patients with keratoconus.
Clinical Investigation of Short-Term Axial Elongation Control After Orthokeratology Lens Correction: Exploring Its Predictive Role in Long-Term Therapeutic Efficacy
Authors: Han Xuemei , Li Feifei , Zhang Yu , Tang Jinfei
Published: October 2024

Objective:

This study was developed with the goal of exploring the efficacy of orthokeratology (OK) as an approach to controlling axial length (AL) growth and identifying factors predictive of the long-term efficacy of this approach.

Methods:

This was a retrospective study that enrolled 157 myopic children 7 to 15 years of age undergoing OK correction for over 3 years. The short- and long-term effectiveness of this approach at 1 and 3 years post-OK correction, respectively, was assessed. All participants were classified into two groups based on whether they exhibited good or poor long-term efficacy outcomes. Measurements of changes in AL were made at baseline and at 1 and 3 years post-OK. Univariate analyses and binary logistic regression approaches were used to evaluate baseline age, baseline spherical equivalent refraction, baseline keratometry (K) values of flat and steep meridians, and short-term effectiveness with the goal of identifying predictors of long-term efficacy.

Results:

Univariate analyses led to the identification of significant differences in baseline age, baseline spherical equivalent refraction, baseline AL, and short-term efficacy between these two groups (P<0.05), whereas gender, baseline flat K, and baseline steep K did not differ significantly (P>0.05). In binary logistic regression analyses, baseline AL (P=0.017) and short-term efficacy (P<0.001) were both found to significantly influence long-term efficacy. Receiver operating characteristic curves demonstrated that short-term efficacy offered an area under the curve value >0.8, consistent with its highly accurate performance as a predictor of long-term efficacy.

Conclusion:

These results suggest that short-term efficacy outcomes can feasibly be used to predict the long-term effectiveness of OK correction in children. In patients exhibiting poor short-term efficacy, timely replacement or the incorporation of additional treatment modalities may aid efforts to better control the progression of myopia.
Reporting outcomes of minimally invasive glaucoma surgery
Authors: Gutkind Naomi E. , Gedde Steven J.
Published: October 2024

Purpose of review

This review presents guidelines for designing studies and reporting efficacy and safety outcomes in minimally invasive glaucoma surgery (MIGS) research.

Recent findings

Adherence to reporting guidelines in MIGS studies is crucial for providers and patients to appraise surgical options. Recent guidelines have outlined appropriate methodology, efficacy outcomes, and safety reporting, so that study results are presented in an interpretable and uniform manner.

MIGS are changing the glaucoma treatment paradigm by offering safer, less invasive alternatives to traditional filtering surgery. However, inconsistent reporting of outcomes in MIGS trials hampers comparison and clinical decision-making. Recent guidelines have aimed to highlight appropriate methodology and encourage standardization in reporting outcomes to improve the quality of MIGS literature. Key considerations include defining baseline intraocular pressure, reporting standardized demographic data, using consistent endpoints, presenting standardized figures, evaluating medication use, and documenting adverse events. By adhering to these guidelines, MIGS trials can offer clearer insights into surgical outcomes, aiding both surgeons and patients in treatment decisions.

Published: October 2024

During the last decade, global health security has been threatened by major Ebola virus disease outbreaks in Western Africa (2014 to 2016) and in eastern Democratic Republic of the Congo (2018 to 2020). Particularly in Western Africa, the outbreak initially overwhelmed health care capacity in already fragile health systems. Thousands of survivors were at risk of newly recognized postacute ocular complications, and their need for urgent ophthalmic care challenged national vision health systems with scarce eye care services. In these unprecedently large outbreaks with implications for global health security, agile eye care responses were challenging, including in regard to decision coordination and requisite logistical needs. In this report, we detail vision care initiatives implemented in response to these outbreaks and highlight the need to include vision care as a critical component of the response to infectious disease outbreaks with eye health implications.

Published: October 2024

Mpox (formerly known as monkeypox), an infectious disease caused by the monkeypox virus (MPXV), has been endemic in regions of Central and Western Africa. In 2022, the global spread of the clade IIb MPXV led to a multinational outbreak, primarily affecting sexual transmission networks among men who have sex with men. Despite interventions, new cases have continued to emerge. In Africa, the spread of a novel strain of clade I MPXV, clade Ib, has prompted a Public Health Emergency of International Concern designation by the World Health Organization in August 2024. This article provides an updated overview of the epidemiology, systemic, and ocular manifestations, highlighting the clinical features, diagnostic testing, and implications relevant to ophthalmologists and eye care providers, including infection prevention and control measures. The ocular manifestations of mpox primarily involve the ocular surface and anterior segment, with presentations ranging from conjunctivitis to severe, vision-threatening keratitis and uveitis. While the 2022 to 2024 Clade IIb outbreak has shown a lower incidence of ocular involvement compared with previous outbreaks, the potential for significant visual morbidity remains. Treatment involves both systemic and topical therapies, with tecovirimat being the primary systemic option, though its efficacy and ophthalmic bioavailability remain under investigation. Ongoing surveillance and research are essential to further understand the epidemiology and ophthalmic features of mpox and, ultimately, to optimize prevention and treatment strategies for patients.
Spinal hyperexcitability in patients with chronic musculoskeletal pain or headache as evidenced by alterations in the nociceptive withdrawal reflex: a systematic review and meta-analysis
Authors: Van Oosterwijck Sophie , Billens Amber , Cnockaert Elise , Danneels Lieven , Mertens Timoti , Dhondt Evy , Van Oosterwijck Jessica
Published: October 2024

The nociceptive withdrawal reflex (NWR) is a spinal withdrawal reflex induced by painful stimulation. It is a measure of spinal hyperexcitability, which is believed to contribute to chronic musculoskeletal pain (MSKP) and headache. Previous syntheses of the evidence for alterations in the NWR in patients with chronic MSKP and headache needed a comprehensive update. This systematic review and meta-analysis was performed after the Preferred Items for Systematic reviews and Meta-Analyses guidelines. Studies examining NWR-related outcome measures in patients with chronic MSKP and headache compared to pain-free controls were identified through electronic database searches and included after screening against predefined eligibility criteria. Standardized mean differences or mean differences and 95% confidence intervals (CI) were calculated. Thirty-one studies were included in the systematic review and 25 in the meta-analysis. Moderate-quality evidence was found indicating lower NWR threshold (−3.68; 95% CI, −4.56 to −2.80; P < 0.001), larger NWR area (standardized mean difference = 0.69; 95% CI, 0.37-1.01; P < 0.001), and shorter NWR latency (mean difference = −13.68; 95% CI, −22.69, −4.67; P = 0.003) in patients compared to controls. These findings remained robust when performing meta-regressions based on subgroups (ie, headache, fibromyalgia, whiplash-associated disorder, and osteoarthritis). Low-quality evidence demonstrated facilitated temporal summation of NWR threshold (−2.48; 95% CI, −3.13 to −1.83; P < 0.001) in patients compared to controls. Spinal hyperexcitability as evidenced by lowered NWR threshold values and temporal summation of the NWR is present in patients with chronic MSKP and headache. No evidence was found for alterations in NWR duration and NWR magnitude. Future research is needed to address the gap in research on NWR-related outcome measures other than NWR threshold.

Authors: Oksen Dogac , Guven Baris , Donmez Ayca , Yesiltas Mehmet Ali , Koyuncu Ahmet Ozan , Gulbudak Seran , Oktay Veysel
Published: October 2024

Introduction

The Naples prognostic score (NPS) is a novel indicator of nutritional and inflammatory statuses in cancer patients. Development of atrial fibrillation after cardiac surgery (POAF) is a common complication that increases the incidence of adverse events. Numerous studies have investigated predictors of POAF. Yet, this study is the first to evaluate the prognostic value of NPS in predicting the development of POAF.

Materials and methods

The population of this retrospective single-center case–control study consisted of all consecutive patients who underwent cardiac surgery between January 2021 and December 2023. The patients included in the study sample were divided into two groups according to whether they had POAF (group POAF) or remained in sinus rhythm (group RSR). Univariate and multivariate analyses were conducted to identify the variables that significantly predicted the development of POAF.

Results

This study consisted of 860 patients with a mean age of 61.77 ± 9.13 years and 77.5% (n = 667) were male. The incidence of POAF in the sample was 24.8% (n = 214). NPS was significantly higher in group POAF than in group RSR (2.18 ± 0.99 vs. 1.96 ± 1.02, P = 0.008). Multivariate analysis revealed age [odds ratio (OR): 1.242, 95% confidence interval (CI): 1.020–1.304, P < 0.001] and high NPS (OR: 1.698, 95% CI: 1.121–1.930, P < 0.010) as independent predictors of POAF.

Conclusion

High NPS values, along with advanced age, were found to be strongly associated with an increased risk of developing POAF. Therefore, it is concluded that NPS is a significant and independent predictor of POAF in patients undergoing cardiac surgery.

Authors: Xue Xiajuan , Lin Shuijie , Zeng Qunzhang , Guo Yincong
Published: October 2024

This study aims to analyze the safety, feasibility, and short-term oncology outcomes of selective laparoscope lateral lymph node dissection (LLND) with total mesorectal excision surgery. Between December 2019 and May 2023, LLND with total mesorectal excision surgery was performed in 47 selected patients with advanced rectal cancer. Surgical complications and 2-year oncology survival outcomes were analyzed in the study. All 47 procedures were technically successful without converting conversion to open surgery. The mean operation time was 200.6 minutes (135–321 minutes), and the mean estimated blood loss was 92.9 mL (range 10–2000 mL). The most common postoperative complications were anastomotic (8.5%, n = 4), ileus (6.4%, n = 3), and chyle leakage (4.3%, n = 2). Lateral pelvic lymph node metastases were found in 19 (40.4%) patients. When divided into lateral pelvic lymph node positive and negative groups, there was no significant impact on overall survival (94.4% vs 100%, Log-rank P = .596) and local recurrence-free survival (LFRS) (76.7% vs 89.6%, Log-rank P = .210), except disease-free survival (DFS) (58.3% vs 90.2%, Log-rank P = .005). Subgroup analysis showed similar short-term survival outcomes between the pN+ group and the internal iliac metastasis group (Log-rank P of overall survival, LFRS, and DFS were all ˃.05). LRFS and DFS in the obturator or external iliac metastasis group were worse than those in the internal iliac metastasis group when the follow-up time was extended (Log-rank P of LFRS and DFS were .05 and .063). Selective laparoscopy LLND for rectal cancer is safety and feasibility, and its complications are manageable. Oncology survival outcomes for lateral pelvic lymph node metastases limited to the internal iliac are similar to the pN+ stage; therefore, it should be treated positively.

Application of NRS2002 and PG-SGA in nutritional assessment for perioperative patients with head and neck squamous cell carcinoma: An observational study
Authors: Tu Yi , Chen Fengzhou , Yu Qing , Song Linglan , Chen Mengmeng
Published: October 2024

This study aimed to compare the effectiveness of 2 nutritional assessment tools, the Nutritional Risk Screening Scale 2002 (NRS2002) and the Patient-Generated Subjective Global Assessment (PG-SGA), for evaluating the nutritional status of perioperative head and neck squamous cell carcinoma (HNSCC) patients, to facilitate early nutritional interventions and improve clinical outcomes. An observational, comparative study was conducted at the Zhejiang Cancer Hospital, recruiting patients diagnosed with HNSCC scheduled for surgical treatment. The NRS2002 and PG-SGA were applied to assess patients’ nutritional risk at multiple time points: upon admission, the day before surgery, 2 days after surgery, a week after surgery, and at discharge. Statistical analyses were performed using McNemar and Kappa tests to assess differences and consistency between NRS2002 and PG-SGA. A total of 209 patients were included in this study, predominantly male, with an average age of 60 years. Nutritional risk assessments identified an inverted “V” trend in nutritional risk, with the peak occurring 2 days post-surgery. PG-SGA consistently showed a higher screening positivity rate compared to NRS2002. The receiver operating characteristic curve analysis highlighted the discriminative power of both tools, with PG-SGA and NRS2002 showing high area under the curve values. Both NRS2002 and PG-SGA are effective for nutritional screening in HNSCC patients, with PG-SGA demonstrating a slightly higher sensitivity before surgery. PG-SGA may be more suitable for preoperative application, whereas NRS2002 is more appropriate for postoperative use.

The aim of this study was to investigate whether leisure screen time (LST) increases the risk of diabetic retinopathy (DR) using the Mendelian randomization (MR). This study employed a two-sample MR analysis, utilizing 63 single-nucleotide polymorphisms as instrumental variables (IVs) to assess the causal relationship between LST and the risk of Dr. To ensure the robustness of the results, a multi-effect test was conducted to evaluate the validity of the IVs. Additionally, heterogeneity tests were performed to explore differences among sub-samples. Sensitivity analyses were also conducted to further validate our findings. The impact of LST on the risk of DR was observed in both inverse variance weighted (odds ratio [OR]: 1.22, 95% confidence interval [CI]: 1.04–1.43, P = 1.38 × 10‐2) and weighted median (OR: 1.30, 95% CI: 1.05–1.61, P = 1.46 × 10‐2) analyses. However, the MR-Egger method (OR: 0.66, 95% CI: 0.32–1.36, P = .273) did not find an increased risk of DR with increased LST. The pleiotropy test yielded a P-value of P = .09. Heterogeneity tests showed that the Q value for the inverse variance weighted method was 71.39 with a P-value of 0.17, indicating no significant heterogeneity. These results suggest that the IVs might be appropriate, and the analysis results could be robust. A large-scale MR analysis suggests a causal relationship between LST and the risk of Dr.
Fatal invasive Aspergillus infection in an elderly patient with hepatitis E: A case report and literature review
Authors: Wu Junjun , Yu Jin , Li Huaming , Wang Yufang , Xu Rong
Published: October 2024

Rationale:

Elderly patients with acute liver failure are highly susceptible to severe complications, such as invasive fungal infections, due to weakened immune systems and altered gut microbiota. A thorough understanding of liver failure and opportunistic infections is crucial for effective management.

Patient concerns:

An 84-year-old male with acute liver failure from hepatitis E experienced worsening jaundice despite standard treatments. He also developed respiratory symptoms, including blood-streaked sputum, raising concerns about a potential fungal infection.

Diagnoses:

The patient was diagnosed with acute liver failure secondary to hepatitis E and an invasive fungal infection caused by Aspergillus fumigatus. Initial treatments included artificial liver plasma exchange and antifungal prophylaxis. Further diagnostics, including bronchoscopy and next-generation sequencing of alveolar lavage fluid, confirmed the Aspergillus infection.

Lessons:

Elderly liver failure patients are particularly prone to opportunistic infections, underscoring the need for vigilant monitoring and early intervention. Despite aggressive treatments, including antifungal therapy and artificial liver support, prognosis remains poor, highlighting the importance of prompt diagnosis and comprehensive management to enhance patient outcomes.
Clinical management and complications of acute appendicitis in 3 children with SARS-CoV-2 infection: Case report
Authors: Filip Florin , Terteliu-Baitan Monica , Avramia Ramona , Filip Roxana , Cocuz Maria Elena
Published: October 2024

Rationale:

Sporadic cases of acute appendicitis (AA) in children with SARS-CoV-2 infection were still recorded at the end of COVID-19 pandemics. We consider that analyses of clinical courses and outcomes is useful to improve the clinical management of such cases in the setting of a general hospital.

Patient concerns:

Patient #1 was a 14-year-old girl who presented with nausea, right lower quadrant (RLQ) pain, myalgia, ad low-grade fever for 24 hours. Patient #2 was a 7-year-old boy with a 3-day history of abdominal pain, nausea and vomiting, and fever lasting for 4 days. Patient # 3 was a 16-year-old girl RLQ pain, nausea and vomiting, and fever lasting for 7 days.

Diagnoses:

The patients were diagnosed with acute appendicitis (AA) based on the clinical picture, labs and abdominal ultrasound (US) findings. SARS-CoV- 2 infection was diagnosed using rapid antigen test performed at admission.

Interventions:

The patients were started on i.v. Ceftriaxone and Metronidazole, antalgics and i.v. fluids at admission. Appendectomy was performed the day after admission in patients # 1 and #2, and after 48 hours in patient #3.

Outcomes:

Patient #1 had no complications and was discharged on postoperative day (POD) #5. Patient #2 developed a cecal fistula on POD #4 which was treated conservatively with Ertapenem, i.v. fluids, and local placement of colostomy bag. The fistula closed spontaneously on POD #12. He was discharged on POD #17. Patient #3 developed a postoperative abscess on POD # 6 and required laparoscopic surgical drainage of the abscess. She was discharged after another 6 days (POD #12). No patient required ICU admission, steroids, or supplemental O2 use during their hospitalization. There were no late complications or readmissions in these patients.

Lessons:

We consider that AA in these SARS-CoV-2 positive children had a similar course with SARS-CoV-2 negative cases. Compliance to previously established COVID-19 protocols was useful to improve the outcome. The parents should bring the sick child early to the hospital in order to avoid complications related to delayed presentation and not to SARS-CoV-2 infection itself.
Unveiling novel prognostic biomarkers and therapeutic targets for HBV-associated hepatocellular carcinoma through integrated bioinformatic analysis
Authors: Ren Xue , Feng Niaoniao
Published: October 2024

Hepatocellular carcinoma (HCC) is a leading cause of cancer-related deaths globally, with limited treatment options. The goal of this study was to use integrated bioinformatic analysis to find possible biomarkers for prognosis and therapeutic targets for hepatitis B (HBV)-associated HCC. Three microarray datasets (GSE84402, GSE121248, and E-GEOD-19665) from patients with HBV-associated HCC were combined and analyzed. We identified differentially expressed genes (DEGs) and performed pathway enrichment analysis. We constructed protein–protein interaction networks to identify hub genes. We identified a total of 374 DEGs, which included 90 up-regulated and 284 down-regulated genes. Pathway enrichment analysis revealed associations with cell cycle, oocyte meiosis, and the p53 signaling pathway for up-regulated DEGs. Twenty hub genes were identified, and 9 of them (ZWINT, MELK, DLGAP5, BIRC5, AURKA, HMMR, CDK1, TTK, and MAD2L1) were validated using the Cancer Genome Atlas data and Kaplan–Meier survival analysis. These genes were significantly associated with a poor prognosis in HCC patients. Our research shows that ZWINT, MELK, DLGAP5, BIRC5, AURKA, HMMR, CDK1, TTK, and MAD2L1 may be useful for predicting how HBV-associated HCC will progress and for finding new ways to treat it. In addition to these further studies are needed to elucidate the functions of the remaining 11 identified hub genes (RRM2, NUSAP1, PBK, CCNB1, CCNB2, BUB1B, NEK2, CENPF, ASPM, TOP2A, and BUB1) in HCC development and progression.

Given the need to measure parents’ perceptions of their children’s exposure to tobacco smoke, the Parental Perceptions of Children’s Exposure to Tobacco Smoke (PPE) instrument was developed and validated in Hebrew and later translated into English and Portuguese. The PPE has already been translated and adapted to the Brazilian context but a more robust sample is necessary to investigate the measurement properties. Thus, this study evaluated the measurement properties of the Brazilian version of the PPE instrument. Reliability and validity study were conducted with 161 parents with children up to 18 years of age. Perception of parental smoking status was investigated using analysis of variance. The instrument showed excellent reliability (Cronbach α = 0.92 and intraclass correlation coefficient = 0.91). The exploratory factor analysis identified 4 factors with a total accumulated variance of 71.6%. Confirmatory factor analysis validated this structure with 4 factors. It was necessary to exclude a question that presented low commonality. Analysis of variance demonstrated that nonsmoking and former smoking parents have similar scores, although they are higher than those of current smokers. Our findings provide evidence that the PPE version translated and adapted for the Brazilian context is a reliable and valid instrument. Thus, it can help us understand how parents cope with exposure to tobacco smoke.

Published: October 2024

Background:

The impact of infraclavicular versus supraclavicular nerve block on the analgesia for upper limb surgeries is unclear. This meta-analysis and systematic review aims to study the analgesic efficacy of infraclavicular versus supraclavicular nerve block for upper limb surgeries.

Methods:

We searched several databases including PubMed, EMbase, Web of science, EBSCO and Cochrane library databases from inception to December 2023, and randomized controlled trials (RCTs) assessing the effect of infraclavicular versus supraclavicular nerve block for upper limb surgeries were included. We excluded studies reporting other nerve block approaches. The methodological quality of the included studies was evaluated by the modified Jadad scale. Standard mean difference with 95% confidence interval (CI) was used to assess continuous outcomes. This meta-analysis was conducted by the fixed-effect model or random-effect model based on the heterogeneity.

Results:

Eight RCTs and 725 patients were included in this meta-analysis. Compared with supraclavicular nerve block for upper limb surgeries, infraclavicular nerve block was able to significantly increase duration of motor block (SMD = 0.34; 95% CI = 0.12 to 0.56) and decrease readiness for surgery (SMD = −0.43; 95% CI = −0.77 to −0.10), but showed similar duration of sensory block (SMD = 0.17; 95% CI = −0.05 to 0.39), block performance time (SMD = −0.14; 95% CI = −0.51 to 0.22), onset of sensory blockade (SMD = −0.13; 95% CI = −0.59 to 0.33) and onset of motor blockade (SMD = −0.17; 95% CI = −0.26 to 0.12). No high heterogeneity was seen among the included studies.

Conclusion:

Infraclavicular nerve block may be superior to control the analgesia for upper limb surgeries than supraclavicular nerve block.
