RESUMEN
OBJECTIVES: Familial Crohn's disease (CD) accounts for approximately 1.5%-22.5% of all CD cases worldwide. We aimed to assess the concordance in disease subtype and phenotypic features among patients with CD and their relatives based on data from a large, well-characterized, referral center-based cohort in China. METHODS: A retrospective study was conducted on patients with familial CD who were admitted to the Sixth Affiliated Hospital of Sun Yat-sen University between January 2012 and June 2022. We analyzed the disease characteristics and performed a concordance analysis within the same family among patients with familial CD. RESULTS: Among 5150 patients, 70 (1.4%) had a family history of Crohn's disease. The median age of the patients at initial diagnosis did not differ significantly between the probands and successors of family members with CD (p = 0.25). At the initial diagnosis, 54 first-degree relatives showed moderate concordance in age (κ = 0.50) and disease location (κ = 0.44). At the last follow-up visit, all family members and first-degree relatives showed good concordance in upper gastrointestinal involvement (κ = 0.67 and 0.62) and stricturing or penetrating behavior (κ = 0.69 and 0.77), respectively. Patients with familial CD within the same family showed moderate agreement regarding anti-tumor necrosis factor α monoclonal antibody use and treatment efficacy (κ = 0.44 and 0.42) and mild agreement regarding the efficacy and adverse reactions of thiopurine (κ = 0.26 and 0.35). CONCLUSIONS: The proportion of patients with familial CD in China may be relatively low. The consistency of certain disease features in familial CD may be associated with the degree of kinship and convergence with longer follow-up duration.
RESUMEN
OBJECTIVES: The objective of this research is to apply machine learning (ML) algorithms to predict the survival of cervical cancer patients. The aim was to address the limitations of traditional statistical methods, which often fail to provide accurate answers due to the complexity of the problem. METHODS: This research employed visualization techniques for initial data understanding. Subsequently, ML algorithms were used to develop both classification and regression models for survival prediction. In the classification models, we trained the algorithms to predict the time interval between the initial diagnosis and the patient's death. The intervals were categorized as "<6 months," "6 months to 3 years," "3 years to 5 years," and ">5 years." The regression model aimed to predict survival time (in months). We used attribute weights to gain insights into the model, highlighting features with a significant impact on predictions and offering valuable insights into the model's behavior and decision-making process. RESULTS: The gradient boosting trees algorithm achieved an 81.55% accuracy in the classification model, while the random forest algorithm excelled in the regression model, with a root mean square error of 22.432. Notably, radiation doses around the affected areas significantly influenced survival duration. CONCLUSIONS: Machine learning demonstrated the ability to provide high-accuracy predictions of survival periods in both classification and regression problems. This suggests its potential use as a decision-support tool in the process of treatment planning and resource allocation for each patient.
RESUMEN
Aspergillus pleurisy is a rare complication of invasive pulmonary aspergillosis (IPA), which mostly occurs in the immunocompromised host. The clinical condition is critical, especially to those who develop bronchopleural fistula. This study aimed to assess the characteristics and the prognosis of aspergillus pleurisy. Clinical data from 13 patients diagnosed with aspergillus pleurisy in our hospital from January 2000 to December 2022 were retrospectively studied. Thirteen patients with Aspergillus pleurisy were included. There were 10 males and 3 females, with a median age of 65 (range: 18-79) years. Bronchopleural fistula was present in eight patients. A proven diagnosis of Aspergillus pleurisy was based on positive pleural fluid culture in seven cases and histopathological examination of pleural biopsies in six cases. Four patients refused further treatment and were discharged from the hospital against medical advice. Nine cases recovered and were discharged after multiple antifungal treatments (systemic and topical antifungal therapies, pleural drainage and irrigation, and surgical repair). During follow-up, one patient, who suffered underlying bronchiectasis, died of massive hemoptysis 2 years after discharge. The remaining eight cases are still under close follow-up, with a median follow-up of 5.4 (range: 1.3-18.9) years. The prognosis of aspergillus pleurisy complicated with bronchopleural fistula is poor. Thoracic surgery, especially lung resection, is a risk factor associated with the incidence of Aspergillus pleurisy. Systemic antifungal therapy and adequate pleural irrigation could improve the prognosis. IMPORTANCE: Aspergillus pleurisy is a rare complication of invasive pulmonary aspergillosis (IPA), associated with a poor prognosis. The morbidity and mortality of this condition have not been thoroughly studied, and recent research on this topic is limited. The current study included 13 patients diagnosed with Aspergillus pleurisy, with the majority presenting concomitantly with a bronchopleural fistula. Among these patients, nine had a history of thoracic surgery, including lung transplantation and lobectomy. Four patients refused further treatment and were discharged against medical advice, while one patient succumbed to massive hemoptysis 2 years after discharge. This case series provides essential insights into Aspergillus pleurisy and evaluates the therapeutic strategy based on a limited cohort.

Background: Allergic parotitis (AP), due to its non-specific symptoms, frequently poses a diagnostic challenge, leading to cases being overlooked or misdiagnosed by clinicians. Objective: This study aimed to elucidate detailed clinical characteristics and common diagnostic indicators of AP. Methods: A comprehensive review and analysis of medical records was conducted from patients diagnosed with AP, encompassing demographic, clinical, and laboratory data, at the Affiliated Stomatological Hospital of Nanjing Medical University between January 2019 and March 2022. Results: The study enrolled 17 patients, evidenced by an average age of 36.00 ± 12.95 years. Common presentations of AP among the patients included notable symptoms such as parotid gland swelling, associated pain, and xerostomia. Ten patients had other atopic diseases. Palpation revealed the affected parotid glands to be soft and nodular, with an elevated local skin temperature. The unstimulated whole saliva flow rate was decreased. Ultrasonography demonstrated increased volume, reduced echo heterogeneity, and lymph node enlargement in the affected parotid glands. All cases observed increased serum salivary amylase and total IgE levels. Investigation of food allergens and inhaled allergen-specific IgE showed that all patients had suspected food allergies. Food provocation tests (FPT) induced AP in 13 cases, confirming the role of food allergens. Conclusion: Food allergens are involved in the etiology of AP, underscoring the importance of comprehensive clinical evaluation, including symptoms, signs, and confirmatory auxiliary tests, such as FPT, for accurate diagnosis and differentiation from other salivary gland pathologies.
RESUMEN
Objective:To analyze the incidence, epidemiology, and clinical characteristics of Creutzfeldt-Jakob disease (CJD) in Guizhou Province from 2017 to 2021 and provide a scientific basis for monitoring of CJD in Guizhou Province.Methods:In this retrospective study, epidemiological and clinical information on suspected CJD cases reported by nine hospitals in Guizhou Province was collected and analyzed based on the laboratory test results of cerebrospinal fluid, blood, and skin samples from the patients.Results:From 2017 to 2021, a total of 47 patients with suspected CJD were reported in Guizhou Province, including 22 confirmed patients. Of these patients, 18 patients (18/22) were clinically diagnosed with sporadic CJD, 2 patients (2/22) were clinically suspected of having sCJD, and 2 patients (2/22) were confirmed to have genetic CJD. All patients primarily presented with rapid progressive dementia, and abnormal magnetic resonance imaging findings of the head are the main auxiliary examination results (16/20). The positive rate of 14-3-3 protein in cerebrospinal fluid was high (14/21). The blood sample PRNP gene testing revealed that 129 amino acids were M/M homozygous, while 219 amino acids were E/E homozygous. Except for T188K and E200K mutations detected by PRNP gene testing in 2 gCJD cases, no other site mutations were found, and 5 cases were positive for skin PrPSc. Patients' geographical distribution showed no obvious clustering. Patients have a wide range of occupations. The male-to-female ratio was 13:9, with a median age of 64 years. The majority of the patients were Han Chinese, and there was no special epidemiological history. Conclusion:The majority of the confirmed CJD patients in Guizhou Province from 2017 to 2021 are sporadic CJD patients, and their residence, occupation, gender ratio, age distribution, and other characteristics are consistent with the incidence patterns of sporadic CJD.
RESUMEN
Objective:To study the clinical characteristics and management strategies of patients with chronic obstructive pulmonary disease (COPD) in high-altitude areas.Methods:An observational cross-sectional study was conducted in 79 stable COPD patients who visited the outpatient of Respiratory Medicine at Tibet Autonomous Region People′s Hospital and Peking University Third Hospital from August 3 rd 2020 to November 30 th 2020. Patients were divided into Lhasa group ( n=44) and Beijing group ( n=35). The differences of clinical characteristics including demographic characteristics, risk factors, respiratory symptoms, comorbidities, medications and spirometry were analyzed. Further comparative analysis was conducted on the clinical characteristics of smokers ( n=15) and non-smokers ( n=29) in Lhasa group. Results:The proportion of female patients and biofuel exposure in Lhasa group was significantly higher than Beijing group (56.8% vs 0, 86.4% vs 0, both P<0.001). The proportion of smokers in Lhasa group was significantly lower than Beijing group (34.1% vs 100%, P<0.001). The mean score of COPD assessment test (CAT) in Lhasa group was significantly higher than Beijing group (21.27 vs 9.17, P<0.001). The proportion of acute exacerbations ≥2 in the past year in Lhasa group was significantly higher than Beijing group (31.8% vs 11.4%, P=0.032). The median percentage of forced vital capacity in the first second of predicted value (FEV 1%pred) of patients in Lhasa group was significantly higher than Beijing group (63% vs 38%, P<0.001). The proportion of patients treated by inhaled corticosteroid/long-acting β 2-agonist (ICS/LABA) and inhaled long-acting muscarinic antagonists (LAMA) in Lhasa group was significantly lower than Beijing group (4.5% vs 60.0%, 0 vs 65.7%, both P<0.001). There were no significant differences in CAT score, number of acute exacerbations in the past year and lung function between smokers and non-smokers in Lhasa group. Conclusions:Compared with those patients in Beijing, the majority of patients with COPD living in Lhasa are female, with a low proportion of smokers and a high proportion of biofuel exposure. Although their lung function is better, their respiratory symptoms are more severe with more acute exacerbations in the past year, and most patients do not receive standardized medication.
RESUMEN
PURPOSE: The epidemiology of eosinophil-associated diseases (EADs) is not yet fully understood. While some studies have been conducted on stand-alone eosinophilic diseases, there is scarce evidence on the degree of overlap among rarer conditions. METHODS: The retrospective Real-world inVestigation of Eosinophilic-Associated disease overLap (REVEAL) study used data from the Optum® Clinformatics® insurance claims database to describe and characterize disease overlap among 11 EADs: allergic bronchopulmonary aspergillosis, atopic dermatitis, chronic rhinosinusitis with nasal polyps, eosinophilic gastritis/gastroenteritis, eosinophilic granulomatosis with polyangiitis, eosinophilic esophagitis, bullous pemphigoid, chronic obstructive pulmonary disorder, chronic spontaneous urticaria, and non-cystic fibrosis bronchiectasis. Patient records with EADs of interest were identified between January 1, 2015, and June 30, 2018. RESULTS: Overall, 1,326,645 patients were included; 74.4% had 1 EAD, 20.5% had ≥ 2 EADs, and 5.1% had ≥ 3 EADs. Higher rates of disease overlap were associated with older age. Higher blood eosinophil counts were also observed in patients with a greater number of overlapping conditions, suggesting a common role for eosinophilic inflammation in the pathogenesis of multiple diseases. Furthermore, greater disease overlap was associated with higher disease severity in most cohorts. CONCLUSIONS: Results from this study have implications for quantifying unmet needs and can be used to inform treatment guidelines and raise the awareness of eosinophilic inflammation and EAD overlap among healthcare professionals from a range of disease specialties.
RESUMEN
OBJECTIVE: To clarify the clinical characteristics of organizing pneumonia (OP) in rheumatoid arthritis (RA; RA-OP) and the association of OP development with RA exacerbation, and to identify OP recurrence predictors. METHODS: Data from 33 patients with RA-OP admitted to our hospital were retrospectively analyzed (2006-2016). RESULTS: RA onset preceded OP onset in 82% of patients, whereas OP onset preceded (OP-preceding) or co-occurred with RA in 9% of patients each. Median age at first OP onset was 64.0 years, and the period from RA onset to first OP onset was 5.5 years. At OP onset, 42% of events exhibited unilateral involvement and 76% had normal Krebs von den Lungen-6. RA disease control remained optimal in 52% of events and was exacerbated in 18% of events. Ten patients (30%) experienced OP recurrence with an interval of 13.0 months between events, and the first OP recurrence rate was 127/1000 person-years. Compared with nonrecurrent cases (n = 14), recurrent cases (n = 10) showed lower age at first OP onset (59.5 vs 67.1 yrs; P = 0.04) and a shorter period from RA onset to first OP onset (6.4 vs 14.2 yrs; P = 0.047); moreover, these cases included a higher number of OP-preceding patients (30% vs 0%; P = 0.03) and ever smokers (80% vs 36%; P = 0.03). OP-preceding patients showed shorter median recurrence-free survival time (15 vs 136 months; P = 0.01) and higher recurrence risk (hazard ratio 5.45; P = 0.02). CONCLUSION: RA-OP showed a high recurrence rate and was not associated with RA exacerbation. Four RA-OP recurrence predictors were identified.

PURPOSE: The study aimed to investigate the clinical characteristics, prognostic factors, survival times, and therapy outcomes of brain metastases (BM) from colorectal cancer (CRC). METHODS: The clinical characteristics of 25 patients with BM from CRC were retrospectively analyzed. The time of the occurrence of BM after diagnosis of CRC was recorded. Meanwhile, the time from the occurrence of lung, bone, liver, and other extracranial metastases to the occurrence of BM was also recorded. We evaluate the time factors affecting the length of the occurrence of BM and the potential prognostic factors after BM diagnosis. The influences of patients undergoing surgery-based comprehensive treatment, radiotherapy-based comprehensive treatment, and co-medication were also assessed. RESULTS: In patients with BM from CRC, lung metastases (13/25) occurred at a higher frequency than liver metastases (8/25) and bone metastases (6/25). The median time to the development of BM was much shorter (3.7 vs. 25.3 months, p = 0.027), with the brain being the origin site for the metastasis. The median overall survival reached 9.9 months. The interval between diagnosis of BM and bone, liver, and lung metastasis remains 3, 6.5, and 11 months, respectively. The brain lesions of patients with BM alone had higher rates in supratentorial (88.9%), while those with extracranial metastasis had a 62.5% incidence of infratentorial metastasis. The difference was statistically significant (p < 0.05). The time of occurrence of BM in patients aged 67 years and younger was 16.1 and 30.1 months, respectively. The differences between them were statistically significant (p = 0.043). The BM time for left- and right-sided colon cancer were 26.5 and 7.8 months, representing a statistically significant difference (p = 0.015). The time to onset of BM for patients with and without the resection of primary lesions was 25.4 and 4.5 months. Statistically significant differences are shown (p = 0.007). Univariate analysis demonstrated that the prognosis of patients was related to the KPS score, the number of BM, the treatment methods, and the occurrence of lung metastasis (p < 0.05). The multivariate analysis revealed that the treatment modality and lung metastasis were independent prognostic factors for CRC patients with BM. Right-sided CRC patients with BM have a poor prognosis (8.1 vs. 10.2 months, p = 0.31). Although median survival time was not significantly different between patients with and without bevacizumab combination therapy, bevacizumab therapy is associated with a better survival time (9.9 vs. 7.1 months, p = 0.27). CONCLUSION: Patients with left-sided CRC, especially those with lung metastases, are prone to brain metastases, and patients with brain metastases as the first metastatic site have a higher rate of supratentorial metastases. Young patients with right hemicolon cancer and patients who have not undergone primary lesion resection have a shorter time for the occurrence of BM. Patients with colorectal lung metastases, especially those young with right-sided CRC, require close imaging surveillance of BM. The prognosis of CRC patients with BM and lung metastases is poor, and comprehensive treatment based on surgery could significantly prolong patients' survival time.

Background: The prevalence of asthma in Taiwan was increasing in the past 30 years, causing a great impact on adolescent health. This study aimed to investigate the current prevalence, impact, and associated factors of asthma in Taiwanese adolescents. Material and methods: Parents or guardians provided passive consent at home prior to the survey. Adolescents aged 13-14 years completed a questionnaire survey in 2017 in Taipei, Taiwan. The prevalence, impact, and associated factors of asthma were analyzed. We also compared the asthma prevalence with the prevalence in 1995 and 2001. Results: We analyzed 3474 validated questionnaires. The prevalence of physician-diagnosed asthma was 12.4%. The prevalence of current wheezing was 9.2% in 2017, which was 5.2% in 1995 and 7.0% in 2001. 3.3% of 13-14-year-old adolescents had severe asthma symptoms. Asthma significantly impacted the lives of adolescents. Of the students with asthma, 10.9% had school absenteeism, 16.5% urgently needed to see a doctor, 9.5% went to the emergency department, and 3.5% were admitted to hospitals within the preceding 12 months. The associated factors for physician-diagnosed asthma in Taiwanese adolescents were male (prevalence ratio [PR], 1.38; 95% confidence interval [CI], 1.05-1.83; p = 0.02), maternal history of asthma (PR, 2.61; 95% CI, 1.69-4.02; p < 0.01), and recent paracetamol use at least once per month (PR, 2.60; 95% CI, 1.24-5.42; p = 0.01). The associated factors for school absenteeism were nocturnal cough (PR, 1.99; 95% CI, 1.16-3.41; p = 0.01), current wheezing (PR, 7.52; 95% CI, 4.39-12.9; p < 0.01), and recent paracetamol use (at least once per month, PR, 3.16; 95% CI, 1.10-9.06; p = 0.03; at least once per year, PR, 2.19; 95% CI, 1.25-3.83; p < 0.01). Conclusions: The prevalence of physician-diagnosed asthma was 12.4%. Asthma substantially impacted the lives of adolescents. Reducing nocturnal cough, wheezing frequency, and paracetamol usage might help decrease school absenteeism.
RESUMEN
BACKGROUND: Limited literature was available on the pattern and determinants of mortality among inborn neonates in comparison to the out born ones. The study's goal was to investigate the patterns and risk factors for mortality among hospitalised, on-ventilator inborn and out born neonates. MATERIALS AND METHODS: It was an unmatched, case-control, pilot study conducted between January and December 2020 using information retrieved from the medical records of patients attending the neonatal intensive care unit (NICU) of a tertiary healthcare facility, namely Narayan Medical College & Hospital, situated in eastern India. RESULTS: Congenital pneumonia was the leading cause of death in inborn neonates, with an overall mortality rate of 33.4%. Meanwhile, the overall fatality rate for out born neonates was found to be 43.3%, with birth hypoxia being the most common cause. The only significant attribute affecting mortality in inborn neonates was low arterial blood gas (ABG) pH, whereas in out born neonates they were prematurity, thrombocytopenia, low ABG pO2, and high pCO2. Overall, new-borns with thrombocytopenia, low ABG pO2, and high pCO2 were observed to be at higher risk for mortality compared to others. CONCLUSION: The mortality rate of out born neonates was higher than inborn ones. The attributes affecting mortality were observed to be prematurity, thrombocytopenia, low ABG pH, pO2, and high pCO2.
RESUMEN
Carbon dioxide is a simple asphyxial gas, with low concentrations having an excitatory effect on the respiratory center, while high concentrations have an inhibitory effect on the respiratory center. Simple carbon dioxide poisoning is rarely seen clinically. This article reviews and analyzes the treatment process of 9 cases of acute inhalation carbon dioxide poisoning in a cargo ship carbon dioxide leakage accident in May 2019, summarizes clinical treatment experience, and provides timely and effective treatment for acute pulmonary edema caused by acute inhalation carbon dioxide poisoning. In particular, the application of hormones has a good prognosis, improving clinicians' understanding of the disease.

INTRODUCTION: Colombia is the fifth most affected country by the global monkeypox outbreak and the second in LAC after Brazil. We describe the clinical and epidemiological characteristics of 521 patients with mpox in the country. METHODS: We conducted an observational analysis of laboratory-confirmed Mpox cases between June 29 and November 16, 2022. RESULTS: Most cases were young men living with HIV. The clinical evolution was primarily benign, with two deaths reported. We found some differences between women and men regarding their BMI, presence of lymphadenopathies, localization of lesions, and the antecedent of HIV infection. CONCLUSION: Although it seems that the epidemic curve for this outbreak of Mpox is decreasing not only in Colombia but globally, it could remain endemic. Therefore, it is necessary to maintain very close surveillance.

OBJECTIVE: To investigate the gut microbiota in newly diagnosed IgA nephropathy patients with chronic kidney disease (CKD) stages 1-2 and the association between the gut microbiota and the clinical risk factors of IgA nephropathy. METHODS: Fresh fecal samples were collected from nineteen newly diagnosed IgA nephropathy patients with CKD stages 1-2 and fifteen age- and sex-matched healthy controls. Fecal bacterial DNA was extracted and microbiota composition were characterized using 16S ribosomal RNA (16S rRNA) high-throughput sequencing for the V3-V4 region. The Illumina Miseq platform was used to analyze the results of 16S rRNA high-throughput sequencing of fecal flora. At the same time, the clinical risk factors of IgA nephropathy patients were collected to investigate the association between the gut microbiota and the clinical risk factors. RESULTS: (1) At the phylum level, the abundance of Bacteroidetes was significantly reduced (P=0.046), and the abundance of Actinobacteria was significantly increased (P=0.001). At the genus level, the abundance of Escherichia-Shigella, Bifidobacte-rium, Dorea and others were significantly increased (P < 0.05). The abundance of Lachnospira, Coprococcus_2 and Sutterella was significantly reduced (P < 0.05). (2) There was no significant difference in the abundance of gut microbiota between the newly diagnosed IgA nephropathy patients and the healthy control group (P>0.05), but there were differences in the structure of the gut microbiota between the two groups. The results of LEfSe analysis showed that there were 16 differential bacteria in the newly diagnosed IgA nephropathy patients and healthy controls. Among them, the abundance of the newly diagnosed IgA nephropathy patients was increased in Enterobacteriales, Actinobacteria, Escherichia-Shigella, etc. The healthy control group was increased in Bacteroidetes and Lachnospira. (3) The result of redundancy analysis (RDA) showed that Bifidobacterium was positively correlated with serum IgA levels, 24-hour urinary protein levels and the presence of hypertension. Lachnoclostridium was positively correlated with the presence of hypertension. Escherichia-Shigella was positively correlated with urine red blood cells account. Bifidobacterium was positively correlated with the proliferation of capillaries. Faecalibacterium was positively correlated with cell/fibrocytic crescents. Ruminococcus_2 was positively correlated with mesangial cell proliferation, glomerular segmental sclerosis and renal tubular atrophy/interstitial fibrosis. CONCLUSION: The gut microbiota in the newly diagnosed IgA nephropathy patients with CKD stages 1-2 is different from that of the healthy controls. Most importantly, some gut bacteria are related to the clinical risk factors of IgA nephropathy. Further research is needed to understand the potential role of these bacteria in IgA nephropathy.

OBJECTIVES: A global outbreak of monkeypox virus infections in human beings has been described since April 2022. The objectives of this study were to describe the clinical characteristics and complications of patients with a monkeypox infection. METHODS: All consecutive patients with a polymerase chain reaction (PCR)-confirmed monkeypox infection seen in a French referral centre were included. RESULTS: Between 21 May and 5 July 2022, 264 patients had a PCR-confirmed monkeypox infection. Among them, 262 (262/264, 99%) were men, 245 (245/259, 95%) were men who have sex with men, and 90 (90/216, 42%) practiced chemsex in the last 3 months. Seventy-three (73/256, 29%) patients were living with human immunodeficiency virus infection, and 120 (120/169, 71%) patients were taking pre-exposure prophylaxis against human immunodeficiency virus infection. Overall, 112 (112/236, 47%) patients had contact with a confirmed monkeypox case; it was of sexual nature for 95% of the contacts (86/91). Monkeypox virus PCR was positive on the skin in 252 patients, on the oropharyngeal sample in 150 patients, and on blood in eight patients. The majority of patients presented with fever (171/253, 68%) and adenopathy (174/251, 69%). Skin lesions mostly affected the genital (135/252, 54%) and perianal (100/251, 40%) areas. Overall, 17 (17/264, 6%) patients were hospitalized; none of them were immunocompromised. Complications requiring hospitalization included cellulitis (n = 4), paronychia (n = 3), severe anal and digestive involvement (n = 4), non-cardia angina with dysphagia (n = 4), blepharitis (n = 1), and keratitis (n = 1). Surgical management was required in four patients. CONCLUSION: The current outbreak of monkeypox infections has specific characteristics: it occurs in the men who have sex with men community; known contact is mostly sexual; perineal and anal areas are frequently affected; and severe complications include superinfected skin lesions, paronychia, cellulitis, anal and digestive involvement, angina with dysphagia, and ocular involvement.

Objective:To investigate the clinical and imaging features of population receiving opportunistic screening for lung cancer and in convalescent stage of COVID-19.Methods:Cross-sectional study and analysis was performed on the patients who underwent chest low-dose CT examination for cancer prevention in Cancer Hospital of Chinese Academy of Medical Sciences from December 28, 2022 to January 19, 2023. All the patients completed the COVID-19 questionnaire. A total of 334 questionnaires were sent out, all of which were recovered, and 321 valid questionnaires were collected, among them, 293 questionnaires were included in the analysis. Statistical analysis was conducted according to the questionnaire information, clinical symptoms and chest CT imaging results. The potential influencing factors of COVID-19 infection were explored, and the imaging characteristics of COVID-19 infection and early stage of lung cancer were compared.Results:A total of 293 patients underwent lung cancer screening during the convalescent stage of COVID-19 infection. A total of 231 (78.8%) cases had cough and 228 (77.8%) cases had fever. 214 (73.0%) cases still had clinical symptoms within 2 weeks after nucleic acid or antigen test showing negative, especially for cough in 171 (58.4%) cases, fatigue in 79 (25.3%) cases and sputum in 73 (24.9%) cases. There were 54 (18.4%) cases with positive chest CT changes. The main imaging findings showed that there were 46 cases with new patchy shadows, 25 cases with linear opacities, 10 cases with ground-glass opacities, 10 cases with nodular like shadows and 2 cases with consolidation, and most lesions were in the subpleural area of both lungs. Univariate analysis showed that positive CT findings were correlated with the time from positive detection of COVID-19 to screening ( P=0.026), age ( P<0.001) and underlying diseases ( P=0.006). Multivariate analysis showed that age≥65 years old ( OR=6.425, 95% CI: 2.688-15.358; P<0.001) and underlying diseases ( OR=2.292, 95% CI: 1.120-4.691; P=0.023) were risk factors for pulmonary imaging changes of COVID-19 infection. For lung cancer opportunistic screening, 36 (12.3%) cases showed ground-glass opacities in bilateral or unilateral lung lobes, among which 4 cases were suspected to be atypical adenomatous hyperplasia and 2 cases s were suspected to be early stage of lung cancer. Conclusions:Abnormal clinical symptoms and chest CT findings are still observed in the patients during the convalescent stage of COVID-19 infection. Age≥65 years, underlying diseases were the high-risk factors for the changes in chest CT imaging after COVID-19 infection. Attention should be paid to the differential diagnosis of chest CT findings between changes in the convalescent stage of COVID-19 and early stage of lung cancer.
RESUMEN
Objective:To analysis the prevalence and characteristics of comorbid insomnia and sleep disordered breathing (SDB) in community population.Methods:This is a cross-sectional study. Cluster sampling was applied. Community residents in Shantou and Meizhou were investigated during April to May, 2021. Essential information collection, sleep related health investigation, and sleep study were conducted. Insomnia was defined as the insomnia severity index (ISI)≥8. A type Ⅳ wearable intelligent sleep monitor was applied for sleep study. Comorbid insomnia and SDB was defined as both diagnosis of insomnia and SDB. Statistical analysis was conducted by SPSS 25. Prevalence and characteristics of insomnia only, SDB only and comorbid insomnia and SDB were analyzed. Logistic regression was conducted to analyze the relationship between sleep disorders and unrestored sleep, abnormal glucose metabolism, hyperlipidemia, and cardiovascular disease.Results:There were 3 730 residents completed the investigation. The median age was 55.0 (46.0, 63.0) years. The prevalence of insomnia only, SDB only, and comorbid insomnia and SDB were 26.0%, 20.2%, and 10.4% respectively. The incidence of unrestored sleep in insomnia only and comorbid insomnia and SDB were 2.900 times and 3.777 times of that in no insomnia or SDB (both P<0.001); the risk of hyperlipidemia was elevated in insomnia only, SDB only and comorbid insomnia and SDB ( OR=1.553, 1.415, and 1.868; all P<0.05); the risk of cardiovascular disease increased 40.8% in SDB only ( P=0.001), and 42.1% in comorbid insomnia and SDB ( P=0.007), after adjusted by age, sex, body mass index (BMI), smoking, drinking, abnormal glucose metabolism, and hyperlipidemia. Stratified analysis revealed that young female (age<60 years) with normal BMI (<25 kg/m 2) and comorbid insomnia and SDB were associated with higher risk of cardiovascular disease. Female with normal body weight and insomnia only or comorbid insomnia and SDB were associated with higher risk of hyperlipidemia. Conclusions:The prevalence of comorbid insomnia and SDB is high in community population. Patients with comorbid insomnia and SDB present with more significant unrestored sleep, and are correlated with higher risk of hyperlipidemia and cardiovascular diseases.
RESUMEN
Objective:To study the clinical characteristics of Lynch syndrome-associated endometrial cancer in elderly patients and the relationship of the disease with MSH2 gene mutations in patients' families.Methods:Clinical data of 473 elderly patients with endometrial cancer admitted to our hospital between January 2016 and January 2021 were retrospectively analyzed.MSH2 gene mutations were detected and verified by DNA sequence analysis, real-time quantitative PCR and reverse transcription PCR.Patients were divided into a Lynch syndrome group and a non-Lynch syndrome group, and the clinicopathological features of the two groups were compared.Results:Of 473 endometrial carcinoma patients, 46(9.7%)had embryogenic mutations of the MMR gene and were diagnosed with Lynch syndrome, with 18, 6, 24 and 10 patients carrying MLH1, PMS2, MSH2 and MSH6 mutations, respectively.There were 3 mutations in the MSH2 gene, including exon 7 1380C>A, exon 12 2011A>G and exon 13 2756A→AC.The proportions of patients with G3 grade endometrioid adenocarcinoma, lower uterine segment involvement and a history of Lynch syndrome-associated malignant tumors in the Lynch syndrome group were significantly higher than those in the non-Lynch syndrome group( χ2=8.935, 8.303, 9.770, all P<0.05). Conclusions:Poorly differentiated endometrioid adenocarcinoma, predisposition to lower uterine segment involvement and familial inheritance are the main clinical manifestations of Lynch syndrome-associated endometrial carcinoma in elderly patients, with the most common mutations seen in the MSH2 gene.
RESUMEN
Objective:To analyze the clinical features in patients of Purtscher-like retinopathy (PLR) associated with COVID-19.Methods:A retrospective clinical study. Clinical data of 4 patients (7 eyes) of PLR associated with COVID-19 which was firstly diagnosed in Department of Ophthalmology, The Second Hospital of The Army Medical University ranging from December 2022 to January 2023 were included. All patients were examined by best-corrected visual acuity (BCVA), color fundus photography, optical coherence tomography (OCT), OCT angiography, fundus fluorescein angiography (FFA), multifocal electroretinogram (mf-ERG), visual field. Oral vasodilators and neurotrophic agents were applied after definite diagnosis. Three patients were treated by intravenous dexamethasone (10 mg) for 3 days. Follow-up time spans for 4 weeks. The multi-model images, clinical features and treatment response of patients were also retrospectively studied.Results:Among 4 patients (7 eyes), 2 cases were male (3 eyes), 2 cases were female (4 eyes), the mean age was (36.00±17.57) years; 3 cases were unilateral, 1 case were unilateral. The time from diagnosis of COVID-19 to the onset of eye symptoms was 2 to 3 days. The BCVA of the affected eye was finger counting for 20 cm to 0.5. Color fundus photography examination revealed that several retinal whitening of varying sizes distributed diffusely on the retina (cotton-wool spots and Purtscher flecken). OCT examination showed that the retinal nerve fiber layer was significantly thickened and the reflex was enhanced in the area corresponding to the gray and white lesions, the inner nuclear layer, internal and external plexus layer segmental and banded strong reflex was observed in 5 eyes. En-face image showed mottled strong reflex in the inner retinal layer and around the deep capillary plexus (DCP). For OCTA, the signal of superficial capillaries and cotton wool spots were lost, and blood flow of deep DCP was poorly distributed. FFA examination showed that the obscured fluorescence of choroid background of Purtscher spot and capillary non-perfusion area. mf-ERG examination showed decreased amplitude of retinal a-wave and b-wave. Visual field examination showed central and paracentral scotoma. During follow-up, the BCVA of diseased eyes were raised, scotomas were shrunk, cotton wool spots and Purtscher flecken became smaller. OCT examination showed that the thickness of the original thickened retinal nerve fiber layer became thinner, the area of the strong reflex area was reduced, and the inner layer of the original segmental strong reflex area was thinner. OCTA examination revealed partial recovery of blood flow signal.Conclusion:For PLR associated with COVID-19, OCT shows thickening of retinal nerve fiber layer, segmental and banding strong reflex in part of the inner layer and inner plexus layers; OCTA is manifested by ischemia in the middle retina and DCP.
RESUMEN
In recent years, with the change of natural and social factors, such as climate warming, urbanization, land reclamation, human population growth, change of life customs, and convenient transportation, the human infectious diseases transmitted by insect vectors, well known as insect-borne infectious diseases, has increased significantly, causing a serious threat to public health. This paper focuses on the epidemiology, clinical characteristics, especially laboratory diagnosis of insect-borne infectious diseases, and emphasizes that medical institutions should pay attention to the rapid and accurate laboratory diagnosis of insect-borne infectious diseases. Metagenomic next generation sequencing has potential value in the diagnosis of insect-borne infectious diseases with unknown causes.
