Long-term outcomes after chest wall resection and repair with titanium bars and sternal plates

Objectives En-bloc complete resection remains the treatment of choice for localized chest wall (CW) tumors. Titanium bars reconstruction demonstrated encouraging results with satisfactory early outcomes. However, long-term outcomes remain under-reported. The purpose of this study is to evaluate long-term outcomes after CW resection and repair with titanium devices. Methods From June 2012 to December 2018, we retrospectively reviewed all patients with CW tumors who underwent surgical resection and repair using titanium. Long-term outcomes were assessed. Results We identified 87 patients who underwent CW tumor resections and titanium reconstruction. Sixty-eight patients were included in the study (excluding benign tumors, Pancoast tumors, palliative surgeries, or clavicle reconstruction). There were 29 sarcomas, 20 isolated CW metastases, eight lung cancers, four breast cancers, three thymic malignancies, two sarcomatoid mesothelioma, and one desmoid tumor. Complete resection was achieved in 64 patients (94%), while R1 resection in four patients (6%). Resection involved one rib in two patients, two ribs in thirteen, three ribs in eighteen, four ribs in nine, five ribs in two, seven ribs in one, partial sternum in fifteen, and full sternum in sixteen patients. No patient experienced flail chest. The 1-year, 3-year, and 5-year overall survival rates and disease-free survivals were 82.3%, 61.4%,57.3%, and 67.6%,57.3%,52.6%, respectively. Surgical site infection occurred in 18% (n = 12) of cases. Eleven of twelve patients had an early infection (<1 year), which required material removal in six patients. Asymptomatic connector unsealing occurred in 6% (n = 4), with only one re-intervention. Titanium allergy has never been reported. Chronic chest pain (lasting more than 3 months after surgery, with daily use of pain killer) was reported in 24% of patients. Conclusion CW resections with titanium reconstruction are associated with long-term survivors. Titanium devices were safe, reliable, and achieved satisfactory oncological results with low morbidity and implant-related complication rates.
Does supplementing β-mannanase modulate the feed-induced immune response and gastrointestinal ecology in poultry and pigs? An appraisal

The provision of adequate and balanced nutrients is critical for efficient and profitable animal protein production. However, non-nutritive components in feedstuffs can elicit responses that can negatively impact nutrient utilization efficiency. For example, dietary β-mannans are recognizable by cell surface mannose receptors are pivotal for diverse cellular functions. This review will evaluate the physiological implications of dietary native β-mannans, the utility of supplemental feed β-mannanase in hydrolyzing β-mannans, and subsequent metabolic responses. Dietary native β-mannans have been implicated in inadvertent stimulation of immune response through a phenomenon called the feed-induced immune response (FIIR), that has been associated with intestinal inflammation and depression in animal performance. Supplemental β-mannanase blunted the FIIR by hydrolyzing native β-mannans to smaller fragments with a reduced ability to stimulate the innate immune system as indicated by the modulation of oxidative stress, mucosal permeability, and blood concentration of acute phase proteins and immunoglobulins in broilers and piglet models. Moreover, β-mannanase hydrolysis of native β-mannans to mannooligosaccharides (MOS) impacted gastrointestinal microbial ecology. Indeed, β-mannanase-derived MOS reduced the concentration of pathogenic bacteria such as Escherichia coli and Salmonella and increased the production of short-chain fatty acids in gastrointestinal tracts of various animal models. Consequently, by hydrolyzing native β-mannans, supplemental β-mannanase may have nutritional, metabolic, and microbial ecology benefits. In summary, integrating multi-functional feed additives such as β-mannanase into feeding programs for monogastric animals will be critical for efficient and sustainable animal protein production in the context of evolving challenges such as the mandated elimination of use of antibiotics for growth promotion.
A comparison of weight gain between HIV exposed uninfected and HIV unexposed uninfected infants who received KMC at Chris Hani Baragwanath Academic Hospital

Introduction Kangaroo Mother Care (KMC) has been associated with improved growth in low birthweight infants and reduction in hypothermia, hypoglycaemia, apnoeas, sepsis, hospital stay, and mortality. The growth of HIV-infected children is poorer than those who are HIV-uninfected. There is paucity of data on weight gain in the HIV-exposed uninfected (HEU) infants compared to HIV-unexposed uninfected (HUU) infants receiving KMC. Aim This study compared the weight gain of HEU and infants HUU from admission to the KMC ward until 12 months corrected age (CA) follow-up visit. Methods Retrospective record review of the neonates admitted in KMC at Chris Hani Baragwanath Hospital over a 2-year period (2012–2013). The weight gain was assessed via weight velocity using the formula; weight/kg/day from admission to KMC to discharge, and g/ week at term, 3, 6 and 9- and 12-months (CA). The demographics were collected and analyzed using Statistica. Results Seventy-seven (129/166) percent of the mothers were HIV negative. HIV negative mothers were younger (25.9 vs. 31.6 years; p = 0.000) and had fewer pregnancies (p = 0.02). There was no difference between the gestational age (30.3 ± 2.53 vs. 30.8 ± 2.88 weeks; p = 0.35) and birthweight (1,345 g ± 234 vs. 1,314 g ± 209; p = 0.47) between HEU and HUU. There were no differences in the weight gain (23.83 g ± 12.2 vs. 23.22 g ± 15.2; p = 0.83) in KMC. There was no differences in weight gain at the different follow-up time points between the two groups. Conclusion Both HEU and HUU groups of infants showed reasonable weight gain despite maternal HIV status.
A functional magnetic resonance imaging examination of audiovisual observation of a point-light string quartet using intersubject correlation and physical feature analysis

We use functional Magnetic Resonance Imaging (fMRI) to explore synchronized neural responses between observers of audiovisual presentation of a string quartet performance during free viewing. Audio presentation was accompanied by visual presentation of the string quartet as stick figures observed from a static viewpoint. Brain data from 18 musical novices were obtained during audiovisual presentation of a 116 s performance of the allegro of String Quartet, No. 14 in D minor by Schubert played by the ‘Quartetto di Cremona. ’ These data were analyzed using intersubject correlation (ISC). Results showed extensive ISC in auditory and visual areas as well as parietal cortex, frontal cortex and subcortical areas including the medial geniculate and basal ganglia (putamen). These results from a single fixed viewpoint of multiple musicians are greater than previous reports of ISC from unstructured group activity but are broadly consistent with related research that used ISC to explore listening to music or watching solo dance. A feature analysis examining the relationship between brain activity and physical features of the auditory and visual signals yielded findings of a large proportion of activity related to auditory and visual processing, particularly in the superior temporal gyrus (STG) as well as midbrain areas. Motor areas were also involved, potentially as a result of watching motion from the stick figure display of musicians in the string quartet. These results reveal involvement of areas such as the putamen in processing complex musical performance and highlight the potential of using brief naturalistic stimuli to localize distinct brain areas and elucidate potential mechanisms underlying multisensory integration.
In vitro physicochemical and biological properties of titanium alloy, zirconia, polyetheretherketone, and carbon fiber-reinforced polyetheretherketone

Implant repair is a common means to restore the normal function of the hard tissues (bone or teeth). At present, the commonly and potentially used implant materials include titanium alloy (Ti), zirconia (Zr), polyetheretherketone (PEEK), and 30% carbon fiber reinforced PEEK (CFR-PEEK). This study compares their physicochemical and biological properties, including surface morphology, contact angle, nano hardness, elastic modulus, and the impact on the proliferation and osteogenic differentiation of bone marrow mesenchyml stem cell. Additionally, the differences in bacteria adhesion rates among materials were compared. CFR-PEEK had the highest contact angle, followed by PEEK, Zr, and Ti. Zr had the highest nano hardness and modulus of elasticity, followed by Ti, CRF-PEEK, and PEEK. There was no statistically significant difference in cytotoxicity among materials based on the liquid extract test. However, the relative cell proliferation rate on the surface of CFR-PEEK was slightly lower than that of Ti and Zr. Moreover, alkaline phosphatase activity, extracellular matrix mineralization, and osteogenic gene expression with the Ti and Zr materials were higher than with the PEEK and CFR-PEEK materials at Day 7, and Zr showed the highest osteogenic gene expression level among materials at Day 14. Ti had the greatest number of bacterial colonies that adhered to it, followed by Zr, CFR-PEEK, and PEEK. While the mechanical properties of PEEK and CFR-PEEK were closer to bone tissue and their anti-adhesion effect against bacteria was better than those of Ti and Zr, modification methods are needed to improve the osteogenic properties of these biopolymers.
Associations of fish oil supplementation with incident dementia: Evidence from the UK Biobank cohort study

Background Although numerous studies have investigated the association of dietary intake of omega-3 fatty acids with cognitive function and the risks of dementia, the relationship between fish oil supplementation and incident dementia in a large population-based cohort study has not yet well studied. Materials and methods A total of 211,094 community-dwelling older persons over 60 years from the UK Biobank cohorts enrolled between 2006 and 2010 that reported regularly taking fish oil and had no dementia at baseline, was included in the present study. All participants completed an electronic questionnaire regarding habitual use of supplements including fish oil. Results Overall, 83,283 (39.5%) participants reported regularly taking fish oil at baseline. Of 211,094 participants with the median age was 64.1 years, 5,274 participants developed dementia events during a median follow-up of 11.7 years, with 3,290 individuals derived from fish oil non-users. In the multivariable adjusted models, the adjusted hazard ratios (HRs) associated with fish oil supplementation for all-cause dementia, vascular dementia, frontotemporal dementia, and other dementia were 0.91 [CI = 0.84–0.97], 0.83 [CI = 0.71–0.97], 0.43 [CI = 0.26–0.72], 0.90 [CI = 0.82–0.98], respectively (all P < 0.05). However, no significant association between fish oil supplementation and Alzheimer’s disease was found (HR = 1.00 [CI = 0.89–1.12], P = 0.977). In the subgroup analyses, the associations between use of fish oil and the risk of all-cause dementia (P for interaction = 0.007) and vascular dementia were stronger among men (P for interaction = 0.026). Conclusion Among older adults, regular fish oil supplementation was significantly associated with a lower risks of incident all-cause dementia, as well as vascular dementia, frontotemporal dementia and other dementia but not Alzheimer’s disease. These findings support that habitual use of fish oils may be beneficial for the prevention of dementia in clinical practice.
Optimal dose of cefotaxime in neonates with early-onset sepsis: A developmental pharmacokinetic model-based evaluation

Objective: The perspective of real-world study is especially relevant to newborns, enabling dosage regimen optimization and regulatory approval of medications for use in newborns. The aim of the present study was to conduct a pharmacokinetic analysis of cefotaxime and evaluate the dosage used in newborns with early-onset sepsis (EOS) using real-world data in order to support the rational use in the clinical practice. Methods: This prospective, open-label study was performed in newborns with EOS. A developmental pharmacokinetic-pharmacodynamic model of cefotaxime in EOS patients was established based on an opportunistic sampling method. Then, clinical evaluation of cefotaxime was conducted in newborns with EOS using real-world data. Results: A one-compartment model with first-order elimination was developed, using 101 cefotaxime concentrations derived from 51 neonates (30.1–41.3°C weeks postmenstrual age), combining current weight and postnatal age. The pharmacokinetic-pharmacodynamic target was defined as the free cefotaxime concentration above MIC during 70% of the dosing interval (70% fT > MIC), and 100% of neonates receiving the dose of 50 mg/kg, BID attained the target evaluated using the model. Additionally, only two newborns had adverse reactions possibly related to cefotaxime treatment, including diarrhea and feeding intolerance. Conclusion: This prospective real-world study demonstrated that cefotaxime (50 mg/kg, BID) had a favorable efficacy and an accepted safety profile for neonates with EOS.
A coupled high resolution atmosphere-ocean model for the BALTEX region

A three-dimensional fully coupled high resolution atmosphere-ocean model for the BALTEX (Baltic Sea Experiment) region has been developed from two independent models, the atmospheric regional model REMO and the Kiel Baltic Sea model. The coupled model was set up in the framework of the BALTEX program to contribute to one of its major objectives, the investigation and quantification of the energy and water cycle in the Baltic Sea and its catchment area. As a first step towards the fully coupled system, sensitivity studies with different forcings for its uncoupled components, the atmosphere and ocean models, were performed. These sensitivity studies demonstrated that both models are able to produce reasonable results which in turn can act as forcing for the respective other model. In the first simulation of the fully coupled system the modeled sea surface temperatures (SST) agree well with satellite observations. Thus they are at least as good as the previously used SSTs from operational analyses and in some cases even better. The detailed evaluation of the coupled model results reveals that often the coupling effects are superimposed by advective influences and that only under specific conditions the atmospheric variables show a remarkable response to different fluxes. The atmosphere-ocean model is coupled directly via the corresponding fluxes across the interface between atmosphere and ocean. For the here presented simulation no flux corrections were necessary. Thus a consistent model system has been developed which can be utilized for further studies of the energy and water cycle in the BALTEX area.
Towards a theoretical framework for the innovation in sustainability reporting: An integrated reporting perspective

Integrated Reporting (IR), as a novel sustainability-oriented organizational reporting approach, is expected to produce better corporate reporting for stakeholders and promote greater transparency and accountability in the capital market. This paper offers a theoretical framework that integrates five mainstream IR theories: stakeholder theory, agency theory, signalling theory, legitimacy theory, and institutional theory. Based on the theoretical framework, there are three drivers for companies to improve their IR disclosure practices: to mitigate information asymmetry between the organisation and all stakeholders; to signal superior quality, legitimacy, and conformity to all stakeholders; and to discharge accountability to all stakeholders. Direct and indirect costs are the main factors that lead to poor IR disclosure practices. This study is the first attempt to construct an integrated theoretical framework for IR. The constructed framework can be adopted as a theoretical foundation for future empirical studies with regard to IR.
A review of respirable fine particulate matter (PM2.5)-induced brain damage

Respirable fine particulate matter (PM2.5) has been one of the most widely publicized indicators of pollution in recent years. Epidemiological studies have established a strong association between PM2.5, lung disease, and cardiovascular disease. Recent studies have shown that PM2.5 is also strongly associated with brain damage, mainly cerebrovascular damage (stroke) and neurological damage to the brain (changes in cognitive function, dementia, psychiatric disorders, etc.). PM2.5 can pass through the lung–gas–blood barrier and the “gut–microbial–brain” axis to cause systemic oxidative stress and inflammation, or directly enter brain tissue via the olfactory nerve, eventually damaging the cerebral blood vessels and brain nerves. It is worth mentioning that there is a time window for PM2.5-induced brain damage to repair itself. However, the exact pathophysiological mechanisms of brain injury and brain repair are not yet fully understood. This article collects and discusses the mechanisms of PM2.5-induced brain injury and self-repair after injury, which may provide new ideas for the prevention and treatment of cerebrovascular and cerebral neurological diseases.
Parametric model-order-reduction development for unsteady convection

A time-averaged error indicator with POD-hGreedy is developed to drive parametric model order reduction (pMOR) for 2D unsteady natural convection in a high-aspect ratio slot parameterized with the Prandtl number, Rayleigh number, and slot angle with respect to the gravity. The error indicator is extended to accommodate the energy equation and Leray regularization. Despite being two-dimensional and laminar, the target flow regime presents several challenges: 1) there is a bifurcation in the angle parameter space; 2) the solution can be multivalued, even at steady state; and 3) the solution exhibits spatio-temporal chaos at several points in the parameter space. The authors explore several reduced-order models (ROMs) and demonstrate that Leray-regularized Galerkin ROMs provide a robust solution approach for this class of flows. They further demonstrate that error-indicated pMOR can efficiently predict several QOIs, such as mean flow, mean Nusselt number and mean turbulent kinetic energy, even in the presence of a bifurcation. Finally, they show that spatio-temporal chaos can lead to lack of reproducibility in both the full-order model and the reduced-order model and that the variance in the full-order model provides a lower bound on the pMOR error in these cases.
Trends in the utilization of psychotropic medications in China from 2018 to 2021

Background: Monitoring psychotropic medicine consumption trends can provide information on the extent of pharmacological interventions for mental disorders and availability of psychotropic medicines. Objectives: This study aimed to illustrate the trends in psychotropic drug utilization in China’s hospitals. Methods: We retrospectively analyzed the aggregated monthly psychotropic procurement records of 1009 hospitals from 31 provinces in China from January 2018 to September 2021. Total psychotropic medicine consumption included the sales of antipsychotics, antidepressants, anxiolytics, mood stabilizers, and sedatives or hypnotics. Information, including generic name, procurement amount, dosage form, strength, purchase time, and geographical data, was collected. Population-weighted psychotropic utilization was expressed in defined daily dose per 1000 inhabitants per day (DDD/1000/day). Results: Psychotropic medicine sales increased from 4.5 DDD/1000/day in Q1 2018 to 6.4 DDD/1000/day in Q3 2021; total utilization in China’s hospitals increased by 42.2%. The use of each class of psychotropics showed a gradually increasing trend. Antidepressants were the most consumed psychotropics, accounting for 48.4% of the total psychotropic utilization (3.1/6.4 DDD/1000/day), followed by sedatives or hypnotics (31.3%; 2.0/6.4 DDD/1000/day) and antipsychotics (15.6%; 1.0/6.7 DDD/1000/day). Among all sub-classes of psychotropics, a most significant growth in DDD per 1000 inhabitants per day was seen for selective serotonin reuptake inhibitors (1.2–1.9 DDD/1000/day), whereas the consumption of typical antipsychotics (from 0.1 to 0.09 DDD/1000/day) and tricyclic antidepressants (from 0.05 to 0.03 DDD/1000/day) decreased during the study period. Psychotropic utilization substantially increased between Q1 2018 and Q3 2021 in regions with different economic levels. In Q3 2021, total psychotropic utilization in secondary and tertiary hospitals was 9.4 DDD/1000/day and 6.0 DDD/1000/day, respectively. Sedatives or hypnotics in secondary hospitals accounted for the largest proportion of utilized psychotropics (43.6%; 4.1/9.4 DDD/1000/day), whereas antidepressants were the most commonly used psychotropic in tertiary hospitals (50.0%, 3.0/6.0 DDD/1000/day). Conclusion: This study showed that despite increases in psychotropic medication use, the consumption of medicines is still much lower than in other countries and regions internationally. With reference to the estimated prevalence of corresponding mental disorders, our study illustrates that a large treatment gap for mental health problems exists in China. In addition, the wide use of psychotropics with weak clinical evidence raises serious concerns regarding rational use. Greater efforts are needed to increase the availability of psychotropic medicines and to facilitate proper psychotropic use.
Disease specific symptoms indices in patients with celiac disease—A hardly recognised entity

Background Celiac disease (CD) was considered a rare disease before and was perceivably only limited to children but now affects almost 1–2% of the global population. This abrupt increase in prevalence is due to advancements in diagnostic criteria and medical facilities but still many countries lack the basic data that can assess the severity of this health issue. The present study was conducted with the aim to assess the common but rarely diagnosed condition with the identification of its underlying secondary ailments. Materials and methods Patients visiting public sector hospitals were recruited and tested for clinical symptoms secondary to gluten-containing foods (wheat and barley, etc.), followed by serological testing for immunoglobulin A, tissue transglutaminase A, and anti-endomysial antibodies. Only seropositive candidates were included in the endoscopic and biopsy examination for the features of villous atrophy and intestinal cell damage. The secondary ailments including anemia, growth retardation, and gastrointestinal symptoms were also documented for the tested positive patients. The modified European Society of Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) criterion was followed throughout the study. Results From 647 suspected cases from March 2018 to July 2019, 113 were confirmed with CD while 58% were female children and 42% were male children. The majority of them were from a lower class (75%) and 26% of them had a positive family history of CD. A total of 67% of patients with CD were underweight while wasting was observed in 38%, and 80% were stunted as well. Of the positively tested patients with CD, 49% had moderate anemia with 15% having severe anemia. Approximately 33% had hypoalbuminemia as well. The majority of them had a mild to severe range of gastrointestinal symptoms, such as abdominal pain, diarrhea, flatus, eructation, diarrhea, and steatorrhea. Conclusion The study finding indicates an increased number of patients diagnosed with CD with an excessive sum of secondary ailments, such as anemia, growth failure, growth retardation, malnutrition, and gastrointestinal symptoms.
