Abstract
Background
We present a case of fungal keratitis caused by Scedosporium apiospermum, which is a rare agent.
Case description
A 34-year-old Caucasian male patient was admitted to our clinic with complaints of pain and blurred vision in the left eye. The patient had a history of wearing contact lenses for 3 years. According to the Snellen chart, the patient’s visual acuity was 20/20 and counting fingers at 30 cm, for right and left eyes, respectively. A 3 × 3 mm corneal abscess at the center of the cornea with hypopyon in the patient’s left eye was observed. After the patient was hospitalized, fortified gentamicin and fortified cefazolin drops were started 24 times per day. Intravenous fluconazole 1 × 800 mg loading, 1 × 400 mg maintenance dose, intravenous vancomycin 4 × 500 mg and intravenous cefoperazone + sulbactam 2 × 2 g treatments were started. We observed S. apiospermum in the corneal scraping sample, which the identification was performed by combined phenotypic characteristics and matrix-assisted laser-desorption ionization time-of-flight mass spectrometry on the sixth day of treatment. The drops were revised as fortified vancomycin, ceftazidime, and voriconazole drops 24 times per day. Intravenous voriconazole 2 × 6 mg/kg loading and 2 × 4 mg/kg maintenance dose treatments were started. Three weeks later, left eye visual acuity increased to 20/40, and the corneal abscess regressed. On second-year follow-up, his visual acuity increased to 20/25 for the left eye and the cornea was transparent.

Conclusion
Scedosporium group is an opportunistic filamentous fungus that is very rarely seen and causes severe keratitis infections. In the literature, to the best of our knowledge, three cases of keratitis due to S. apiospermum after contact lenses were reported, and all were treated with penetrating keratoplasty. In this case, unlike the others, only medical treatment was applied. In cases with suspected fungal keratitis, medical treatment should be started without waiting for the culture result, the findings should be followed and penetrating keratoplasty should be performed in the case of no response to treatment.

Abstract
Background
Hematopoietic stem cell transplantation (HSCT) is the main treatment for acute radiation sickness, especially after fatal radiation. The determination of HSCT for radiation patients is mainly based on radiation dose, hemogram and bone marrow injury severity. This study aims to explore a better biomarker of acute radiation injury from the perspective of systemic immune response.

Methods
C57BL/6J female mice were exposed to total body irradiation (TBI) and partial body irradiation (PBI). Changes in haptoglobin (Hp) level in plasma were shown at different doses and time points after the exposure and treatment with amifostine or bone marrow transplantation. Student’s t-test/two tailed test were used in two groups. To decide the Hp levels as a predictor of the radiation dose in TBI and PBI, multiple linear regression analysis were performed. The ability of biomarkers to identify two groups of different samples was determined by the receiver operating characteristic (ROC) curve. The results were expressed as mean ± standard deviation (SD). Significance was set at P value < 0.05, and P value < 0.01 was set as highly significant. Survival distribution was determined by log-rank test.

Results
In this study, we found that Hp was elevated dose-dependently in plasma in the early post-irradiation period and decreased on the second day, which can be used as a molecular indicator for early dose assessment. Moreover, we detected the second increase of Hp on the 3rd and 5th days after the lethal irradiation at 10 Gy, which was eliminated by amifostine, a radiation protection drug, while protected mice from death. Most importantly, bone marrow transplantation (BMT) on the 3rd and 5th day after 10 Gy radiation improved the 30-days survival rate, and effectively accelerated the regression of secondary increased Hp level.

Conclusions
Our study suggests that Hp can be used not only as an early molecule marker of radiation injury, but also as an important indicator of bone marrow transplantation therapy for radiation injury, bringing new scientific discoveries in the diagnosis and treatment of acute radiation injury from the perspective of systemic immunity.

Abstract
Background
The continuous mutation of severe acute respiratory syndrome coronavirus 2 has made the coronavirus disease 2019 (COVID-19) pandemic complicated to predict and posed a severe challenge to the Beijing 2022 Winter Olympics and Winter Paralympics held in February and March 2022.

Methods
During the preparations for the Beijing 2022 Winter Olympics, we established a dynamic model with pulse detection and isolation effect to evaluate the effect of epidemic prevention and control measures such as entry policies, contact reduction, nucleic acid testing, tracking, isolation, and health monitoring in a closed-loop management environment, by simulating the transmission dynamics in assumed scenarios. We also compared the importance of each parameter in the combination of intervention measures through sensitivity analysis.

Results
At the assumed baseline levels, the peak of the epidemic reached on the 57th day. During the simulation period (100 days), 13,382 people infected COVID-19. The mean and peak values of hospitalized cases were 2650 and 6746, respectively. The simulation and sensitivity analysis showed that: (1) the most important measures to stop COVID-19 transmission during the event were daily nucleic acid testing, reducing contact among people, and daily health monitoring, with cumulative infections at 0.04%, 0.14%, and 14.92% of baseline levels, respectively (2) strictly implementing the entry policy and reducing the number of cases entering the closed-loop system could delay the peak of the epidemic by 9 days and provide time for medical resources to be mobilized; (3) the risk of environmental transmission was low.

Conclusions
Comprehensive measures under certain scenarios such as reducing contact, nucleic acid testing, health monitoring, and timely tracking and isolation could effectively prevent virus transmission. Our research results provided an important reference for formulating prevention and control measures during the Winter Olympics, and no epidemic spread in the closed-loop during the games indirectly proved the rationality of our research results.

AbstractThe pathological hallmarks of Parkinson’s disease (PD) are α-synuclein (αSYN)-positive inclusions referred to as Lewy bodies and Lewy neurites, collectively referred to as Lewy-related pathology (LRP). LRP is thought to propagate in an ascending manner throughout the brain as the disease progresses. LRP is visible with histologic methods and is thought to represent a later stage of the disease process, while αSYN oligomers, which are not visible with routine histologic methods, are considered earlier. There is increasing evidence to suggest that αSYN oligomers may be more toxic than visible LRP. Detecting αSYN oligomers requires special techniques, and their distribution and association with clinical features are important research objectives. In this report, we describe the distribution of αSYN oligomers in multiple cortical and subcortical regions of PD using a proximity ligation assay (PLA). We observe widespread distribution of αSYN oligomers with PLA and more restricted distribution of LRP with αSYN immunohistochemistry. The distribution of αSYN oligomers differed from LRP in that αSYN oligomer burden was significantly greater in the neocortex, while LRP was greater in vulnerable subcortical regions, including the brainstem. We also found that cognitive impairment was associated with αSYN oligomers in the hippocampus. These results suggest that αSYN oligomers may be widely distributed in PD early in the disease process and that they may contribute to cognitive impairment in PD.

Published: September 2022

AbstractBackgroundThe rapid spread of COVID-19 required swift action to provide people with rheumatic and musculoskeletal diseases (RMDs) with reliable information. People with limited health literacy constitute a vulnerable group that might have difficulty accessing, understanding and applying health information, particularly in times of crisis.ObjectivesThis study explored (a) key aspects of crisis communication and (b) explicit consideration of people’s health literacy needs in communication to people with RMDs during the first wave of COVID-19 in the Netherlands.MethodsWe conducted a convergent, qualitatively driven mixed-methods study comprising seven qualitative interviews with professional representatives of organisations responsible for information provision to people with RMDs, and quantitative analysis of 15 patient information materials distributed by these organisations. The study was guided by principles of crisis communication and health literacy. We assessed understandability and actionability of information materials using the Dutch version of the Patient Education Materials Assessment Tool (PEMAT, resulting in a percentage of quality criteria met), and language difficulty level using an online application (assessing difficult words, jargon, passive, complex and long sentences, long paragraphs, and difficulty levels according to the Common European Framework of Reference for Languages (CEFR, from A1 (basic) to C2 (proficient))).ResultsRespondents reported lack of preparedness, challenges related to scientific uncertainty and reaching the target group, difficulty simplifying information, and uncertainty regarding adequacy of the communication approach. Patient information materials (written and video) showed variation in actionability (range 60–100%) and understandability (range 58–100%), and 69% of written materials were too difficult, mostly due to the use of long sentences and difficult words. The quantitative findings were in coherence with the limitations in communication reported by respondents. Several potential improvements were formulated in ‘lessons learned’.ConclusionsAlthough rheumatology organisations mostly adhered to principles of crisis communication and made efforts to adapt information to their audience’s needs, we propose recommendations to improve preparedness, strategy, content, reach and consideration of health literacy needs in future crisis communication.
Prevalence and associated factors of depression among people with epilepsy in Ethiopia: a cross-sectional study
Authors: Seid Jemal , Mebrahtu Kalayu 
Published: September 2022

Abstract
Background
Depression is the most common comorbid psychiatric disorders that affect people with epilepsy. We aim to determine the prevalence of depression and associated factors among people with epilepsy.

Results
The prevalence of depression was found to be 34.8%. Unable to read and write (AOR = 0.400, 95% CI: 0.162, 0.986), long duration of the medication intake at least for 11 years (AOR = 3.715, 95% CI: 1.498, 9.212), absence of improvement with antiepileptic drugs (AOR = 0.216, 95% CI: 0.101, 0.460), feeling of perceived stigma (AOR = 0.244, 95% CI: 0.129, 0.462), stress symptoms (AOR = 0.452, 95% CI: 0.220, 0.928), were significantly associated with depression.

Conclusions
Prevalence of depression among people with epilepsy was high. Therefore, early screening and management is mandatory. This is the first research study, to our knowledge, that evaluates the association between substance use, sexual and physical abuse among people with epilepsy with depression. Therefore, future research needs to investigate the association.
Percutaneous coronary artery intervention in unprotected left main coronary artery disease: one-year outcome Egyptian registry
Authors: Ayman Rana , Shaheen Sameh Mohamed , Sabet Sameh Saleh , Abdellatif Yasser A. 
Published: September 2022

Abstract
Background
Left main coronary artery lesions are associated with jeopardy of an outsized area of the myocardium, causing a high incidence of morbidity and mortality. Optimal treatment of coronary bifurcation anatomy remains highly debatable, whether by provisional or two-stent technique. This prospective observational study was designed to investigate the one-year clinical outcomes of unprotected left main coronary artery disease revascularization by percutaneous coronary intervention in a “real-world” setting among Egyptian patients in a prospective single-center registry (at Ain Shams University Hospitals).

Results
This study included 163 patients who underwent PCI to LM lesions between May 1, 2020, and the end of April in Ain Shams University hospitals. Patients were dichotomized into two groups according to their intended stenting technique, whether provisional or two-stent technique. A total of 142 underwent provisional stenting while 21 were designated for the two-stent technique, mainly DK crush (double kissing). Among the patients with intended provisional stenting, 34 patients underwent the TAP technique. Patients were followed up for the primary endpoints, at the in-hospital setting, at 30 days, and after 1 year. In-hospital death was encountered in 6.34% of cases undergoing provisional stenting, among which 5.36% were due to a cardiovascular cause. Total MACCE was found to be 2.96% in the provisional stenting group versus 4.76% in the two-stent group. Overall, MACCE at 1 year was found to be 22.31% in the provisional group and 30% in the two-stent group (p-value0.57). TVF was recognized in 10% of cases treated by provisional stenting and 30% of cases treated by the two-stent technique (p-value 0.023).

Conclusions
LM coronary artery lesions treatment by PCI is considered a safe and beneficial solution. Provisional stenting is the preferred approach bearing in mind that bail-out procedures may be sought in case the SB needs further treatment. Adjunctive assessment by IVUS or FFR may help achieve better outcomes, and efforts should be performed to facilitate their feasibility.
Drugs acting on the renin–angiotensin–aldosterone system (RAAS) and deaths of COVID-19 patients: a systematic review and meta-analysis of observational studies
Authors: Sharma Ruchika , Kumar Anoop , Majeed Jaseela , Thakur Ajit K. , Aggarwal Geeta 
Published: September 2022

Abstract
Background
Angiotensin-converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARBs) are two of the most commonly used antihypertensive drugs acting on the renin–angiotensin–aldosterone system (RAAS). Previous research has shown that RAAS inhibitors increase the expression of angiotensin-converting enzyme, a cellular receptor for the severe acute respiratory syndrome coronavirus 2, raising concerns that the use of ACEi and ARBs in hypertensive patients may increase COVID-19 patient mortality. Therefore, the main aim of the current study was to find out the role of drugs acting on RAAS, particularly ACEi/ARBs in the deaths of COVID-19 patients.

Results
In total, 68 studies were found to be appropriate, reporting a total of 128,078 subjects. The odds ratio was found to be 1.14 [0.95, 1.36], which indicates the non-significant association of ACEi/ARBs with mortality of COVID-19 patients. Further, the association of individual ACEi/ARBs with mortality of COVID-19 patients was also found non-significant. The sensitivity analysis results have shown no significant effect of outliers on the outcome.

Conclusions
Based on available evidence, ACEi/ARB were not significantly associated with deaths of COVID-19 patients.
Congenital nodular fasciitis: an extremely rare entity with review of literature
Authors: Wagner Till , Ulrich Dietmar 
Published: September 2022

Abstract
Background
Nodular fasciits is thought to be a benign superficial nodular disease, which most often occurs in the medium age of adolescence, mainly in the subcutaneous or fascial plane on the upper extremities and trunk. The percentage of this entity in children compared to adults is less than 10%. Most cases in childhood were reported at the head and neck region, therefore often renamed to cranial or extracranial fasciitis. These lesions often consists of sarcoma like structures. Preoperative imaging is often unspecific and the standard of treatment in children is biopsy or in some cases complete resection with narrow margin depending on size or location of the lesion.

Case presentation
We present a clinical case of a female newborn with a congenital nodular presternal mass. Biopsy revealed nodular fasciits by testing on USP6 gen rearrangement. With ongoing growth of her nodular thoracic tumor, she underwent complete resection with primary closure. We followed her clinical course over more than 3 years and give a review of the literature.

Conclusion
Only a minority of reports are documented with a neonate onset and none with a real congenital. We hereby presented the first case in literature of a proven congenital fasciits other than cranial/extracranial in a newborn and her clinical course.
End-of-Life Health Resource Utilization for Limited English-Proficient Patients With Advanced Non–Small-Cell Lung Cancer
Authors: Leung Bonnie , Wong Selina K. , Ho Cheryl 
Published: September 2022

PURPOSE: Limited English-proficient (LEP) patients with non–small-cell lung cancer (NSCLC) may receive less palliative care services and more likely to receive aggressive end-of-life (EoL) care. Goals of this retrospective cohort study are to compare access to community palliative home care (CPHC), do not resuscitate (DNR) form completion, place of death, and health resource utilization at EoL between English-proficient (EP) and LEP patients with NSCLC in Vancouver, Canada. METHODS: All patients with advanced NSCLC referred in 2016 and received medical care were included. Patients were classified as LEP if seen with a medical interpreter. Descriptive statistics and univariate and multivariate analyses were used to compare the outcomes between the two groups. RESULTS: One hundred eighty-six patients were referred, 66% EP. Rates of CPHC referral and DNR form completion were the same for both groups (84% and 92%, P = 1.00). LEP patients received earlier access to CPHC (15 v 10 weeks before death, P = .039). Rates of ER visits within 6 months and 30 days of death were 0.89 for EP patients and 0.7 for LEP patients, P = .374, and 0.1 for EP patients and 0.13 for LEP patients, P = .244. Hospitalization rates within 6 months and 30 days of death were 1.4 for EP patients and 1.59 for LEP patients, P = .640, and 0.67 for EP patients and 0.81 for LEP patients, P = .091. EP patients were more likely to have a home death (26% v 14%), whereas LEP patients died in acute care (23% v 14%) or a tertiary palliative care unit (24% v 19%). This was not statistically significant ( P = .335). LEP patients had better median overall survival (8.5 v 5.4 months, P < .001), but when controlled by age, mutation, and EP status, only receipt of palliative-intent systemic therapy was statistically significant. CONCLUSION: EP and LEP patients with NSCLC have similar referral rates to CPHC, DNR form completion, and EoL health resource utilization. The measured EoL variables did not demonstrate significant disparities between EP and LEP patients.

AbstractContextThe evidence regarding bicarbonate status and mortality among diabetes is scarce.ObjectiveThe purpose of this study was to investigate the associations of bicarbonate concentrations with risk of all-cause, cardiovascular disease (CVD), and cancer mortality among patients with type 2 diabetes (T2D).MethodsThis study included 8163 adult diabetic patients from the National Health and Nutrition Examination Survey (NHANES), 1999 to 2018. Death outcomes were ascertained by linkage to National Death Index records through 31 December 2019. The Cox proportional-risk model was used to estimate hazard ratios (HR) and 95% CIs for mortality from all causes, CVD, and cancer. The mediating effects of 11 metabolic, cardiovascular, and renal biomarkers were evaluated using a logistic regression model within a counterfactual framework.ResultsDuring 8163 person-years of follow-up, 2310 deaths were documented, including 659 CVD deaths and 399 cancer deaths. After multivariate adjustment, lower serum bicarbonate levels were significantly linearly correlated with higher all-cause, CVD, and cancer mortality: The risk of all-cause death increased by 40%, the risk of CVD death increased by 48%, and the risk of cancer death increased by 84% compared with the normal group (all P &lt; .05). Altered levels of estimated glomerular filtration rate explained 12.10% and 16.94% of the relation between serum bicarbonate with all-cause and CVD mortality, respectively. Total cholesterol mediated 4.70% and 10.51% of the associations of all-cause and CVD mortality, respectively.ConclusionLower serum bicarbonate concentrations were significantly associated with higher all-cause, CVD, and cancer mortality. These findings suggest that maintaining adequate bicarbonate status may lower mortality risk in individuals with T2D.
