Authors: Schwartz Carolyn E. , Borowiec Katrina , Rapkin Bruce D. 
Published: July 2023

AbstractPurposeThis study characterized depression trajectories during the COVID pandemic and investigated how appraisal and changes in appraisal over time related to these depression trajectories.MethodsThis longitudinal study of the psychosocial impact of the COVID-19 pandemic included 771 people with data at three timepoints over 15.5 months. The depression index was validated using item-response-theory methods and receiver-operating-characteristic curve analysis. The Quality of Life (QOL) Appraisal Profilev2Short-Form assessed cognitive-appraisal processes. Sequence analysis characterized depression-trajectory groups, and random effects models examined appraisal main effects, appraisal-by-group, and appraisal-by-group-by-time interactions.ResultsSequence analysis generated six trajectory groups: Stably Well (n = 241), Stably Depressed (n = 299), Worsening (n = 79), Improving (n = 83), Fluctuating Pattern 1 (No–Yes–No; n = 41), and Fluctuating Pattern 2 (Yes–No–Yes; n = 28). While all groups engaged in negative appraisal processes when they were depressed, the Stably Depressed group consistently focused on negative aspects of their life. Response-shift effects were revealed such that there were differences in the appraisal-depression relationship over time for standards of comparison and recent changes for the Stably Depressed, and in health goals for those Getting Better.ConclusionThe present work is, to our knowledge, the first study of response-shift effects in depression. During these first 15.5 pandemic months, group differences highlighted the connection between negative appraisals and depression, and response-shift effects in these relationships over time. Egregious life circumstances may play a lesser role for the Stably Depressed but a greater role for people who have transient periods of depression as well as for those with improving trajectories (i.e., endogenous vs. reactive depression). How one thinks about QOL is intrinsically linked to mental health, with clear clinical implications.

Abstract
Background
Given the importance of chest computed tomography (CT) to differentiate congestion from COVID-19 pneumonia, and considering the association of chest CT findings with cardiac biomarkers in patients with concomitant COVID-19 and heart failure, this study was conducted to identify the correlation between plasma NT-proBNP level and radiographic features of congestion in patients with COVID-19. This retrospective cohort research was carried out on adult hospitalized patients with COVID-19 and the plasma concentration of NT-proBNP was measured. The most important findings in chest CT have been considered to differentiate COVID-19 pneumonia from congestion. The study population was divided into two groups based on the presence of these imaging characteristics.

Results
Totally, 180 patients with a mean age of 59.6 ± 14.6 years were included in the research. The radiographic findings related to congestion have been found in chest CT of 107 (59.4%) patients. Mean plasma concentration of NT-proBNP in patients with and without radiographic features of congestion was 9886.5 ± 12,676 and 2079.9 ± 4209.3 pg/mL, respectively (p < 0.001). The area under the curve of plasma levels of NT-proBNP for identification of patients with COVID-19 who had pulmonary vein enlargement in chest CT was 0.765 (95% CI 0.688–0.842) and 0.731 (95% CI 0.648–0.813) for the individuals who had interlobar fissure thickening (p < 0.001).

Conclusions
The diagnostic accuracy of plasma NT-proBNP and its positive correlation with radiographic features of congestion in chest CT scan of patients with COVID-19 can be helpful for administering appropriate medications to prevent blood volume overload.

Published: July 2023

Abstract
Background
Bronchial asthma may mimic different diseases regarding their similar clinical presentations, so accurate assessment is required to exclude other possible diagnosis before confirming the diagnosis of bronchial asthma. The aim of the study was to identify the percentage of patients in whom the diagnosis of current asthma was confirmed or ruled out after clinical, spirometric assessment, and utilizing all the possible investigations.

Methods
A cohort study of newly diagnosed bronchial asthma in adults aged ≥ 18 years were recruited from chest outpatient clinic and chest department. History taking, clinical examination, chest X-ray, and spirometry were done for all patients, while chest high-resolution computed tomography (HRCT), CT pulmonary angiography, or different endoscopies were done when indicated.

Results
Two hundred recently clinically diagnosed asthmatic patients were recruited with a mean age of 43.2 and 53.4 years in the asthma group and asthma rule out group, respectively. About 55.5% of the studied patients were ruled out to have bronchial asthma after serial assessments of symptoms and spirometric function. There was increased chest wheeze as a respiratory symptom among asthma patients than the other group (p ˂ 0.001), while hemoptysis was significantly a more presenting symptom among patient group whose asthma diagnosis is ruled out (p = 0.009). About 87.6% of asthma confirmed group showed predominant reversible airway obstructive. The sputum cytology analysis of the bronchial asthma group of patients was 42.7% eosinophilic, 24.7% neutrophilic, and 32.6% mixed cellularity. After consuming all the available investigational tools, the most common diseases found among asthma rule out group were cardiac disorders, chronic obstructive pulmonary disease, psychological disorders, rhinitis, and gastro-esophageal reflux disease with percent of 11.5%, 9%, 8.5%, 8%, and 6%, respectively.

Conclusions
Utilizing all the available investigational tools in the present study allowed to exclude bronchial asthma and diagnose critical diseases that need specific and urgent therapies as heart diseases, subglottic stenosis, pulmonary hypertension, and interstitial lung diseases.

Solitary fibrous tumor of pleura presenting as respiratory failure: unusual presentation of a rare tumor
Authors: Layek Avishek , Anthony Michael Leonard , Darbari Anshuman , Mishra Mayank 
Published: July 2023

AbstractSolitary fibrous tumors of the pleura (SFTPs) are rare primary pleural tumors derived from sub-mesothelial mesenchymal tissue that are mostly incidentally diagnosed in asymptomatic subjects. Symptomatic SFTPs usually present with dry cough and chest pain. We report the case of a 55-year-old lady with a 9-month history of shortness of breath, right-sided chest pain, and heaviness, who presented to our institute with hypercapnic respiratory failure and later required invasive mechanical ventilation. Subsequent radiological and histopathological investigations led to the diagnosis of a benign SFTP occupying almost the entire right hemithorax. She was treated with complete surgical resection by thoracotomy resulting in immediate resumption of adequate ventilation in the postoperative period. We emphasize the importance of large pleural tumors as a rare but reversible cause of hypercapnic respiratory failure.

Published: July 2023

BackgroundPerinatal mental health (PMH) problems are a leading cause of maternal death and increase the risk of poor outcomes for women and their families. It is therefore important to identify the barriers and facilitators to implementing and accessing PMH care.AimsTo develop a conceptual framework of barriers and facilitators to PMH care to inform PMH services.MethodRelevant literature was systematically identified, categorised and mapped onto the framework. The framework was then validated through evaluating confidence with the evidence base and feedback from stakeholders (women and families, health professionals, commissioners and policy makers).ResultsBarriers and facilitators to PMH care were identified at seven levels: individual (e.g. beliefs about mental illness), health professional (e.g. confidence addressing perinatal mental illness), interpersonal (e.g. relationship between women and health professionals), organisational (e.g. continuity of carer), commissioner (e.g. referral pathways), political (e.g. women's economic status) and societal (e.g. stigma). The MATRIx conceptual frameworks provide pictorial representations of 66 barriers and 39 facilitators to PMH care.ConclusionsThe MATRIx frameworks highlight the complex interplay of individual and system-level factors across different stages of the care pathway that influence women accessing PMH care and effective implementation of PMH services. Recommendations are made for health policy and practice. These include using the conceptual frameworks to inform comprehensive, strategic and evidence-based approaches to PMH care; ensuring care is easy to access and flexible; providing culturally sensitive care; adequate funding of services and quality training for health professionals, with protected time to complete it.
Height and Growth Velocity in Children and Adolescents Undergoing Obesity Treatment: A Prospective Cohort Study
Authors: Putri Resthie R , Danielsson Pernilla , Marcus Claude , Hagman Emilia 
Published: July 2023

Abstract

Context
Pediatric obesity affects endocrine conditions, which may alter growth.

Objective
This work aimed to investigate the effect of obesity severity and obesity treatment outcome on growth.

Methods
This prospective cohort study included children (aged 3-18 years) enrolled in the Swedish Childhood Obesity Treatment Register (BORIS) (1998-2020). Obesity was categorized as class I and class II obesity. Obesity treatment outcome was measured as body mass index (BMI) z score changes and categorized into good (BMI z score reduction of ≥0.25), intermediate, and poor (increasing BMI z score). Height for age z score, final height, and growth velocity were compared between class I and class II obesity. Further, the effect of obesity treatment outcome on growth velocity during 2-year follow-up was assessed.

Results
A total of 27 997 individuals (mean age 10.2 ± 3.6 years) were included. Individuals with class II obesity were on average taller than those with class I obesity during childhood. Among males, reduced growth spurt was observed in class I obesity, and even absent in class II obesity. Females exhibited a similar but less pronounced pattern. Good obesity treatment outcome yielded lower growth velocity at ages 3 to 9 years but higher growth velocity at ages 10 to 13 years compared to poor treatment outcome.

Conclusion
Obesity severity is positively associated with height and growth velocity in childhood. A hampered growth spurt during puberty should be anticipated, particularly in adolescents with severe obesity. Therefore no difference in final height between class I and class II obesity is expected. Successful obesity treatment does not harm, but rather normalizes, the growth velocity pattern.
Low ceruloplasmin levels exacerbate retinal degeneration in a hereditary hemochromatosis model
Authors: Anderson Brandon D. , Lee Timothy , Bell Brent , Song Ying , Dunaief Joshua L. 
Published: July 2023

ABSTRACT
In a previous report, a 39-year-old patient with high serum iron levels from hereditary hemochromatosis (HH) was diagnosed with a form of retinal degeneration called bull's eye maculopathy. This is atypical for patients with HH, so it was theorized that the low serum levels of ferroxidase ceruloplasmin (CP) of this patient coupled with the high iron levels led to the retinal degeneration. CP, by oxidizing iron from its ferrous to ferric form, helps prevent the oxidative damage caused by ferrous iron. To test this, a hepcidin knockout (KO) mouse model of HH was combined with Cp KO to test whether the combination would lead to more severe retinal degeneration. Monthly in vivo retinal images were acquired and, after 11 months, mice were euthanized for further analyses. Both heterozygous and homozygous Cp KO increased the rate and severity of retinal degeneration. These results demonstrate the protective role of CP, which is most likely owing to its ferroxidase activity. The findings suggest that CP levels may influence the severity of retinal degeneration, especially in individuals with high serum iron.
Comparison of auditory evoked potential thresholds in three shark species

Published: July 2023

ABSTRACT
Auditory sensitivity measurements have been published for only 12 of the more than 1150 extant species of elasmobranchs (sharks, skates and rays). Thus, there is a need to further understand sound perception in more species from different ecological niches. In this study, the auditory evoked potential (AEP) technique was used to compare hearing abilities of the bottom-dwelling New Zealand carpet shark (Cephaloscyllium isabellum) and two benthopelagic houndsharks (Triakidae), the rig (Mustelus lenticulatus) and the school shark (Galeorhinus galeus). AEPs were measured in response to tone bursts (frequencies: 80, 100, 150, 200, 300, 450, 600, 800 and 1200 Hz) from an underwater speaker positioned 55 cm in front of the shark in an experimental tank. AEP detection thresholds were derived visually and statistically, with statistical measures slightly more sensitive (∼4 dB) than visual methodology. Hearing abilities differed between species, mainly with respect to bandwidth rather than sensitivity. Hearing was least developed in the benthic C. isabellum [upper limit: 300 Hz, highest sensitivity: 100 Hz (82.3±1.5 dB re. 1 µm s−2)] and had a wider range in the benthopelagic rig and school sharks [upper limit: 800 Hz; highest sensitivity: 100 Hz (79.2±1.6 dB re. 1 µm s−2) for G. galeus and 150 Hz (74.8±1.8 dB re. 1 µm s−2) for M. lenticulatus]. The data are consistent with those known for ‘hearing non-specialist’ teleost fishes that detect only particle motion, not pressure. Furthermore, our results provide evidence that benthopelagic sharks exploit higher frequencies (max. 800 Hz) than some of the bottom-dwelling sharks (max. 300 Hz). Further behavioural and morphological studies are needed to identify what ecological factors drive differences in upper frequency limits of hearing in elasmobranchs.

Abstract
Background
Esophagojejunostomy after minimally invasive total gastrectomy (MITG) for gastric cancer (GC) is technically challenging. Failure of the esophagojejunal anastomosis can lead to significant morbidity, leading to short- and long-term quality of life (QoL) impairment or mortality. The optimal reconstruction method following MITG remains controversial. We evaluated outcomes of minimally invasive esophagojejunostomy after laparoscopic or robotic total gastrectomies.

Methods
We retrospectively reviewed MITG patients between 2015 and 2020 at two high-volume centers in China and the United States. Eligible patients were divided into groups by different reconstruction methods. We compared clinicopathologic characteristics, postoperative outcomes, including complication rates, overall survival rate (OS), disease-free survival rate (DFS), and patient-reported QoL.

Results
GC patients (n = 105) were divided into intracorporeal esophagojejunostomy (IEJ, n = 60) and extracorporeal esophagojejunostomy (EEJ, n = 45) groups. EEJ had higher incidence of wound infection (8.3% vs 13.3%, P = 0.044) and pneumonia (21.7% vs 40.0%, P = 0.042) than IEJ. The linear stapler (LS) group was inferior to the circular stapler (CS) group in reflux [50.0 (11.1–77.8) vs 44.4 (0.0–66.7), P = 0.041] and diarrhea [33.3 (0.0–66.7) vs 0.0 (0.0–66.7), P = 0.045] while LS was better than CS for dysphagia [22.2 (0.0–33.3) vs 11.1 (0.0–33.3), P = 0.049] and eating restrictions [33.3 (16.7–58.3) vs 41.7 (16.7–66.7), P = 0.029] at 1 year. OS and DFS did not differ significantly between LS and CS.

Conclusions
IEJ anastomosis generated better results than EEJ. LS was associated with a better patient eating experience, but more diarrhea and reflux compared with CS. Clinical and patient-reported outcomes show the superiority of IEJ with the LS reconstruction method in MITG for GC.

Introduction: Leishmaniasis is a disease with high mortality rates and approximately 1.5 million new cases each year. Despite the new approaches and advances to fight the disease, there are no effective therapies. Methods: Hence, this study aims to screen for natural products' structural analogs as new drug candidates against leishmaniasis. We applied Computer-aided drug design (CADD) approaches, such as virtual screening, molecular docking, molecular dynamics simulation, molecular mechanics–generalized Born surface area (MM–GBSA) binding free estimation, and free energy perturbation (FEP) aiming to select structural analogs from natural products that have shown anti-leishmanial and anti-arginase activities and that could bind selectively against the Leishmania arginase enzyme. Results: The compounds 2H-1-benzopyran, 3,4-dihydro-2-(2-methylphenyl)-(9CI), echioidinin, and malvidin showed good results against arginase targets from three parasite species and negative results for potential toxicities. The echioidinin and malvidin ligands generated interactions in the active center at pH 2.0 conditions by MM-GBSA and FEP methods. Conclusions: This work suggests the potential anti-leishmanial activity of the compounds and thus can be further in vitro and in vivo experimentally validated.

Published: July 2023

Background: Capitulum mitella is a widely distributed and ecologically important stalked barnacle that settles extensively on rocky shores. This species contributes to the structural complexity of intertidal habitats and plays a critical role in the marine ecosystem. This study aimed to reveal the genetic diversity and population structure of C. mitella by analyzing the mitochondrial cytochrome oxidase I (COI) gene. Methods: A 683bp fragment of the COI gene was sequenced from 390 individuals sampled from six localities in Fujian, China. Results: A total of 84 distinct haplotypes were identified through the analysis of 82 polymorphic sites, resulting in an average haplotype diversity (h) of 0.660 and nucleotide diversity (π) of 0.00182. Analysis of molecular variance (AMOVA) and pairwise FST statistics showed no significant population structure. Neutrality tests and mismatch distributions provided evidence of recent population expansion for the species. Conclusions: We suggest that the species' high dispersal ability, and ocean currents coupled with limited physical barriers in the region, contribute to its current phylogeographic structure. These findings enhance our comprehension of the genetic diversity and population structure of C. mitella, providing valuable insights for future conservation efforts.

Published: July 2023

Background: The problem of missing teeth persists in all age groups. The main objective of implants in dentistry is to provide a restoration that reconstructs the shape and restores esthetics and functions of edentulous areas. The objectives of this study are to compare the crestal bone level changes and papillary fill after placement of implants in fresh extraction socket, i.e. immediate implant placement, and healed extraction socket, i.e. delayed or conventional implant placement, and to assess other clinical parameters such as modified plaque index (mPI), modified gingival index (mGI) and gingival biotype in between the groups and within the groups. Methods: 18 patients were recruited in the study out of which 9 patients received implants as per immediate implant placement protocol (group 1) and 9 patients received implants as per conventional implant placement protocol (group 2). All patients were evaluated for gingival biotype, mPI and mGI and papillary fill was assessed as per Jemt’s papilla score as clinical parameters. Implant site was assessed for radiographic bone loss using Image J software. Statistical analysis was performed using independent t test, paired t test and chi square test. Results: At the end of 1 year, results showed that crestal bone loss was seen more in the immediate group than the conventional group. Conventional implants showed better papillary fill than implants placed in fresh extraction sockets. Plaque scores were assessed as per modified plaque index, which showed better results in the conventional group. Modified gingival index was used to assess gingival status which showed better results in the immediate group one year later. Conclusions: Findings from the study suggest that crestal bone loss was found to be increased in the immediate group than the conventional group and papillary fill was better in the conventional group than the immediate group.
