Persistencia de signos y síntomas a los 6 meses posinfección por chikungunya en pacientes de un hospital público en Paraguay

Introducción: El virus chikungunya (CHIKV) causa una enfermedad con manifestaciones agudas bien documentadas, pero existen pocos datos sobre la persistencia de síntomas y secuelas a largo plazo. Objetivos: Evaluar la persistencia de signos, síntomas y factores asociados en pacientes con infección por CHIKV en un seguimiento de 6 meses posinfección. Materiales y métodos: Estudio de cohorte ambispectivo que incluyó casos confirmados de CHIKV notificados en abril de 2023 en Coronel Oviedo, Paraguay. Se realizaron entrevistas al mes, a los tres meses y a los 6 meses posinfección. Se analizaron características demográficas, comorbilidades, manifestaciones reumáticas y sintomáticas. Resultados: Ingresaron 333 participantes, completando seguimiento a 6 meses 170 pacientes. A los 6 meses persistieron: dolor de espalda (61.2%), artritis (57.1%), cefalea (54.1%), fatiga (51.2%), mialgia (49.4%), debilidad (47.6%), depresión (45.9%) y artralgia (45.9%). La persistencia de artritis (OR 7.54; p=0.008) y mialgia (OR 3.24; p=0.031) a 6 meses fue mayor en el grupo de 36-45 años. Conclusiones: Alta persistencia de síntomas musculoesqueléticos y fatiga hasta 6 meses posinfección, con tendencia decreciente, pero exacerbación de depresión. Edad entre 36-45 años asociada a mayor persistencia. Se requieren protocolos de seguimiento integral, investigar mecanismos fisiopatológicos y fortalecer prevención, dado el impacto individual y socioeconómico de la enfermedad.

Introduction: Chikungunya virus (CHIKV) causes a disease with well-documented acute manifestations, but there is limited data on the persistence of symptoms and long-term sequelae. Objectives: To evaluate the persistence of signs, symptoms, and associated factors in patients with CHIKV infection during a 6-month post-infection follow-up. Material and Methods: An ambispective cohort study that included confirmed cases of CHIKV reported in April 2023 in Coronel Oviedo, Paraguay. Interviews were conducted at 1, 3 and 6 months post-infection. Demographic characteristics, comorbidities, rheumatic, and symptomatic manifestations were analyzed. Results: 333 participants were enrolled, with 170 patients completing the 6-month follow-up. At 6 months, the following symptoms persisted: back pain (61.2%), arthritis (57.1%), headache (54.1%), fatigue (51.2%), myalgia (49.4%), weakness (47.6%), depression (45.9%), and arthralgia (45.9%). The persistence of arthritis (OR 7.54, p=0.008) and myalgia (OR 3.24, p=0.031) at 6 months was higher in the 36-45 age group. Conclusions: High persistence of musculoskeletal symptoms and fatigue up to 6 months post-infection, with a decreasing trend but exacerbation of depression. Age between 36-45 years was associated with greater persistence. Comprehensive follow-up protocols, investigation of pathophysiological mechanisms, and strengthening prevention are required, given the individual and socioeconomic impact of the disease.

Seguimiento de niños con diagnóstico de asma grave antes y durante la pandemia por COVID-19 / Follow-up of children diagnosed with severe asthma before and during the COVID-19 pandemic

En la pandemia por COVID-19 se exploraron estrategias de atención para garantizar el seguimiento de niños con asma grave. Estudio prospectivo, observacional, comparativo. Se incluyeron pacientes del programa de asma grave de un hospital pediátrico de tercer nivel (n 74). Se evaluó el grado de control, exacerbaciones y hospitalizaciones durante un período presencial (PP), marzo 2019-2020, y uno virtual (PV), abril 2020-2021. En el PP, se incluyeron 74 pacientes vs. 68 (92 %) del PV. En el PP, el 68 % (46) de los pacientes presentaron exacerbaciones vs. el 46 % (31) de los pacientes en el PV (p 0,003). En el PP, se registraron 135 exacerbaciones totales vs. 79 en el PV (p 0,001); hubo una reducción del 41 %. En el PP, el 47 % (32) de los pacientes tuvieron exacerbaciones graves vs. el 32 % (22) de los pacientes en el PV (p 0,048). Hubo 91 exacerbaciones graves en el PP vs. 49 en el PV (p 0,029), reducción del 46 %. No hubo diferencias en las hospitalizaciones (PP 10, PV 6; p 0,9). La telemedicina fue efectiva para el seguimiento de pacientes con asma grave

During the COVID-19 pandemic, health care strategies were explored to ensure the follow-up of children with severe asthma. This was a prospective, observational, and comparative study. Patients in the severe asthma program of a tertiary care children's hospital were included (n: 74). The extent of control, exacerbations, and hospitalizations during an in-person period (IPP) (March 2019­2020) and an online period (OP) (April 2020­2021) was assessed. A total of 74 patients were enrolled in the IPP compared to 68 (92%) in the OP. During the IPP, 68% (46) of patients had exacerbations versus 46% (31) during the OP (p = 0.003). During the IPP, 135 total exacerbations were recorded compared to 79 during the OP (p = 0.001); this accounted for a 41% reduction. During the IPP, 47% (32) of patients had severe exacerbations versus 32% (22) during the OP (p = 0.048). A total of 91 severe exacerbations were recorded during the IPP compared to 49 during the OP (p = 0.029); the reduction was 46%. No differences were observed in terms of hospitalization (IPP: 10, OP: 6; p = 0,9). Telemedicine was effective for the follow-up of patients with severe asthma.

Seguimiento Funcional hasta Seis Meses después de Sobrevivir a Cuidados Intensivos: Lecciones aprendidas de un Estudio Chileno Multicéntrico / Functional follow-up six months after surviving intensive care: lessons learned from a Chilean multicenter study

Introducción. Las tasas de retención en los estudios de seguimiento oscilan entre el 32 y 100%, demostrando el desafío que implica realizar estudios longitudinales de sobrevivientes de la unidad de cuidados intensivos (UCI). Objetivo. Identificar las estrategias implementadas y lecciones aprendidas en un estudio prospectivo multicéntrico de seguimiento de sobrevivientes de la UCI durante la pandemia. Métodos. Estudio post-hoc de las lecciones aprendidas mediante encuestas y entrevistas dirigidas a explorar la experiencia de los investigadores y coordinadores del estudio IMPACCT COVID-19, realizado en siete centros chilenos entre octubre 2020 y abril 2021 evaluando el síndrome post-cuidados intensivos de sobrevivientes hasta seis meses después. Resultados. Identificamos ocho lecciones: 1) selección de instrumentos de medición, 2) identificación de centros participantes, 3) aprobación del estudio, 4) financiamiento, 5) capacitación de evaluadores, 6) coordinación/aseguramiento de calidad, 7) reclutamiento y 8) seguimiento de pacientes. Incluso durante el primer año de pandemia, reclutamos 252 pacientes a una tasa de 1,4 pacientes/día con una retención del 48% a los 6 meses de seguimiento. El uso de redes académicas existentes y las estrategias de comunicación entre investigadores, coordinadores y evaluadores fueron aspectos positivos; mientras que la fidelización con evaluadores al egreso de la UCI y con pacientes durante el seguimiento son aspectos que deberían considerarse en futuros estudios. Conclusiones. Se evaluaron más de 250 pacientes en seis meses durante la pandemia, con tasas de retención post UCI acorde a la literatura. Futuros estudios debiesen optimizar los procesos de medición y de seguimiento para minimizar la pérdida de pacientes.

Background. Retention rates of follow-up studies range from 32 to 100%, demonstrating the challenge to conduct longitudinal studies of intensive care unit (ICU) survivors. Objective. To identify the strategies implemented and lessons learned in a multicenter prospective follow-up study of ICU survivors during pandemic times. Methods. Post-hoc study of lessons learned through surveys and interviews aimed at exploring the experience of the researchers and coordinators of the IMPACCT COVID-19 study. The original study was performed in seven Chilean sites between October 2020 and April 2021 evaluating the post-intensive care syndrome of survivors up to six-month follow-up. Results. We identified eight lessons: 1) selection of measurement instruments, 2) identification of participating sites, 3) Study approval, 4) funding, 5) evaluators training, 6) coordination/quality assurance, 7) recruitment, and 8) patient follow-up. Even during the first year of the pandemic, we recruited 252 patients at a rate of 1.4 patients/day with a retention rate of 48% at 6 months of follow-up. The use of existing academic networks and communication strategies between researchers, coordinators and evaluators were positive aspects; while evaluators fidelity at ICU discharge and patient engagement during follow-up are aspects should be considered. Conclusions. More than 250 patients were evaluated in six months during the pandemic, with post-ICU retention rates consistent with the literature. Future studies should optimize measurement and monitoring processes to minimize patient atrition.

Longitudinal study on anxiety and intolerance of uncertainty among Chinese college students / 中国学校卫生

Objective@#To explore the longitudinal changes and related predictive factors of anxiety and intolerance of uncertainty (IU) among Chinese college students, so as to provide theoretical reference for promoting students mental health.@*Methods@#Intolerance of Uncertainty Scale-short Form and the 7 item Generalized Anxiety Disorder Scale were administered among 5 683 students from 22 universities in Guangdong Province from September 10 to October 17, 2021 (T1, baseline survey), and from March 15 to April 22, 2023 (T2). Using paired sample t-test to analyze the changes in anxiety and IU among college students, a linear regression model was established to explore factors that can predict anxiety, IU and their changes during T1 and T2 periods.@*Results@#During the T1 period, the average scores of anxiety and IU among college students were (3.26±3.46, 34.88±7.96), while during the T2 period, they were (4.41±4.16, 36.40±8.07). During the T2 period, the levels of anxiety and IU among college students were higher than those during the T1 period ( t=19.59, 13.67, P <0.01). The linear regression results showed that age ( B = -0.02 ), moderate ( B =-0.18) and poor ( B =-0.88) mental health status, as well as online browsing of Corona Virus Disease 2019 (COVID-19) epidemic (later called as epidemic) related information for >1-<3 hours ( B =-0.30) and ≥3 hours ( B =-0.22), all of which could negatively predict changes in anxiety during T1 to T2 periods. Living in rural areas ( B =0.11) could positively predict changes in anxiety during T1 to T2 periods ( P <0.05). Moderate ( B =-0.19) and poor ( B =-0.47) mental health status, browsing epidemic related information online for >1-<3 hours ( B =-0.32) and ≥3 hours ( B =-0.33), academic performance being moderately affected by the epidemic ( B =-0.10), and personal planning being moderately affected by the epidemic ( B =-0.13) and severely affected ( B =-0.22), all of which could negatively predict changes in IU during T1 to T2 periods ( P <0.05).@*Conclusions@#Levels of anxiety and intolerance of uncertainty increases significantly after epidemic. Mental health status of college students should need long term monitoring, and students with poor mental health should need special attention.

The data was organized, categorized and discussed using descriptive summaries. Results 10 studies made up the final sample, two with nurses only and the others with nurses and physicians. The main outcomes assessed were perforation and expulsion, with no significant differences between the professionals who performed the procedure. Success rates, continuity and satisfaction were similar between physicians and nurses. Conclusion the outcomes of intrauterine device insertions by nurses in health institutions are similar to those carried out by physicians, with increased access, without increasing the complications related to this contraceptive method, contributing to comprehensive care in the field of reproductive planning. Contributions to practice: the findings could help nurses to tackle barriers and serve as a basis for guidelines and health policies that encourage the insertion of the intrauterine device by these professionals, especially in contexts where this practice does not yet take place.

Functional status of children and adolescents with COVID-19 in a reference hospital in southern Brazil / Estado funcional de crianças e adolescentes com COVID-19 em um hospital de referência no sul do Brasil

Abstract Introduction COVID-19 could leave important consequences, including functional decline. Objective Eval-uate functional status in pediatric patients hospitalized with COVID-19 and correlate with clinical variables. Methods Prospective and retrospective longitudinal study with patients with COVID-19. Hospitalization data were collected from medical record review and post discharge data were collected by telephone contact. Functional status was evaluated by Functional Status Scale (FSS-Brazil) in three moments (hospital admission, hospi-tal discharge and after hospital discharge). Spearman test was used to correlate continuous variables and the linear model with generalized estimation equations was used to verify differences in the proportion of functional impairment occurrence (FSS-Brazil ≥ 8) at different mo-ments of the study and previous disease presence. Results It was included 232 patients, 56% male, median age of five years old. Seventy (30.2%) patients had post discharge data. The mean global score of FSS-Brazil was 7.3 at hospital admission, 6.8 at discharge hospital and 6.8 after discharge hospital. Functional status was adequate in the three different moments evaluated in 75% of the sample. The ventilatory support needed was not correlated with functional status and the length of hos-pital stay and oxygen therapy showed weak correlations with functional status. Having no previous disease reduced the risk of functional impairment by 94%. Conclusion The majority of the patients maintained adequate functional status. Absence of previous disease was a protective factor for long term functional impairment.

Resumo Introdução A COVID-19 pode deixar sequelas impor-tantes, como declínio funcional. Objetivo Avaliar a funcionalidade dos pacientes pediátricos internados com COVID-19 e correlacionar com variáveis clínicas. Métodos Estudo longitudinal retrospectivo e prospectivo, com pacientes pediátricos com COVID-19. Os dados de internação hospitalar foram coletados a partir da revisão de prontuários e os dados pós-alta através de contato telefônico. A funcionalidade foi avaliada através da Escala de Estado Funcional Pediátrica (FSS-Brasil) em três momentos (admissão, alta e pós-alta hospitalar). A correlação entre as variáveis contínuas foi avaliada pelo teste de Spearman e utilizou-se o modelo linear com equações de estimação generalizada para verificar as diferenças nas proporções de ocorrência de prejuízo funcional (FSS-Brasil ≥ 8) nos diferentes momentos do estudo e na presença de doenças prévias. Resultados Foram incluídos 232 pacientes, 56% do sexo masculino, mediana de 5 anos de idade. Foram obtidos dados de seguimento pós-alta hospitalar de 70 (30,2%) crianças. O escore global médio da FSS-Brasil foi de 7,3 na admissão, 6,8 na alta e 6,8 após a alta. A funcionalidade apresentou-se adequada nos três momentos de avalia-ção em 75% da amostra. A necessidade de suporte ven-tilatório não foi correlacionado com a funcionalidade, e o tempo de internação e oxigenoterapia apresentaram correlações fracas com a funcionalidade. A inexistência de doenças prévias reduziu em 94% o risco de prejuízo funcional. Conclusão A maioria das crianças manteve funcionalidade adequada. Não ter doenças prévias foi um fator de proteção para o prejuízo funcional em longo prazo.

Prognostic Impact of Residual Moderate Mitral Regurgitation Following Valve-in-Valve Transcatheter Aortic Valve Implantation

ABSTRACT Introduction: The impact of mitral regurgitation (MR) on valve-in-valve transcatheter aortic valve implantation (VIV-TAVI) in patients with failed bioprostheses remains unclear. The purpose of this study was to assess the prognostic impact of residual moderate MR following VIV-TAVI. Methods: We retrospectively analyzed 127 patients who underwent VIV-TAVI between March 2010 and November 2021. At least moderate MR was observed in 51.2% of patients before the procedure, and MR improved in 42.1% of all patients. Patients with postoperative severe MR, previous mitral valve intervention, and patients who died before postoperative echocardiography were excluded from further analyses. The remaining 114 subjects were divided into two groups according to the degree of postprocedural MR: none-mild MR (73.7%) or moderate MR (26.3%). Propensity score matching yielded 23 pairs for final comparison. Results: No significant differences were found between groups before and after matching in early results. In the matched cohort, survival probabilities at one, three, and five years were 95.7% vs. 87.0%, 85.0% vs. 64.5%, and 85.0% vs. 29.0% in the none-mild MR group vs. moderate MR-group, respectively (log-rank P=0.035). Among survivors, patients with moderate MR had worse functional status according to New York Heart Association (NYHA) class at follow-up (P=0.006). Conclusion: MR is common in patients with failed aortic bioprostheses, and improvement in MR-status was observed in over 40% of patients following VIV-TAVI. Residual moderate MR after VIV-TAVI is not associated with worse early outcomes, however, it was associated with increased mortality at five years of follow-up and worse NYHA class among survivors.

Antibody Response to SARS-COV-2 Vaccination in Healthcare Workers of Uttarakhand: A Prospective Follow-up Study

Background: Countries around the world are now racing to vaccinate people against SARS-CoV-2, the virus that causes COVID-19. The Government of India also rolled out its vaccination drive from 16th January ‘2021. Aims: To estimate the antibody response of the COVID-19 vaccine in the form of SARS-COV-2 IgG antibodies in vaccinated healthcare workers. Methods: Prospective follow-up was study conducted on healthcare workers (HCWs) of a Medical college in Dehradun, Uttarakhand. Healthcare workers who have been vaccinated for COVID-19 were tested for SARS-CoV-2-IgG antibodies at regular intervals i.e at 4 weeks after the 1st dose and then again at 4 weeks after the 2nd dose. The third sample was taken 6 months after the 2nd dose. Results: A total of 302 HCWs were enrolled in the study who gave their samples for IgG antibody estimation after the Covishield vaccine. After 4 weeks of completion of both doses, 96% HCWs formed SARS-COV-2 IgG antibodies, whereas 4% didn’t. Then after 6 months of follow-up, 14% HCWs have become negative for antibodies and better immunity is seen in people who also got infected with COVID-19 during this time. Conclusion: This study concludes that the immunity gained after vaccination is waning off in around 6 months and there is a need for a booster dose, especially for people at high risk. The infection control practices still play a crucial role in the prevention of this deadly disease.

Objetivo: Evaluar la reducción, la colocación del implante y el tiempo de consolidación. Métodos: Se realizó un estudio descriptivo, longitudinal y prospectivo de 114 pacientes con diagnóstico de fracturas del extremo proximal del fémur tratadas con clavo femoral proximal, y un seguimiento posoperatorio de un año. Resultados: Se alcanzó un resultado clínico funcional de excelente a bueno en el 82,4 % de los casos. Se evidenciaron signos radiológicos de consolidación en un promedio de 4,2 meses en la mayor parte de la muestra. Conclusiones: La pérdida de la fijación constituyó la complicación más frecuente; por tanto, se considera que el enclavado femoral proximal ofrece buenos resultados en el tratamiento de fracturas intertrocantéricas inestables del fémur.

Introduction: Intertrochanteric fractures of the proximal end of the femur constitute the nosological group with the highest morbidity and mortality of traumatic skeletal injuries. Objective: To evaluate reduction, implant placement and consolidation time. Methods: A descriptive, longitudinal and prospective study was carried out in 114 patients with diagnosis of fractures of the proximal end of the femur treated with proximal femoral nailing, and a one-year postoperative follow-up. Results: A functional clinical result from excellent to good was achieved in 82.4% of the cases. Radiological signs of consolidation were evidenced in an average of 4.2 months in most of the sample. Conclusions: Loss of fixation was the most frequent complication; therefore, proximal femoral nailing is considered to offer good results in the treatment of unstable intertrochanteric fractures of the femur.

Acute Type A Aortic Dissection and Late Pregnancy: What Should We Do?

ABSTRACT Introduction: Acute type A aortic dissection (AAAD) in late pregnancy is a rare but severe disease. Lack of clinical experience is the main cause of high mortality. This study tries to investigate the multidisciplinary therapeutic strategy for these patients. Case presentation: We reported three patients with AAAD in late pregnancy. Sudden chest pain was the main clinical symptom before operation. All three patients and their newborns survived through multidisciplinary approach in diagnosis and treatment. No serious complications occurred during the mid-term follow-up. Conclusion: Multidisciplinary diagnosis and treatment strategy play a crucial role in saving the lives of pregnant women with AAAD.

Logro de control metabólico temprano en adultos con diabetes mellitus tipo 2 en Perú

Objetivo: Estimar la proporción de sujetos con diabetes mellitus tipo 2 (DMT2) que alcanzan la meta terapéutica para HbA1C un año después del diagnóstico (control metabólico temprano). Métodos: Revisión retrospectiva de historias clínicas de adultos atendidos en 16 centros médicos distribuidos en nueve ciudades peruanas. Se incluyeron pacientes que recibieron un diagnóstico inicial de DMT2 y tuvieron al menos un año de seguimiento. Se consideraron las metas metabólicas definidas en los estándares ADA 2018. Resultados: Se incluyeron 457 sujetos (53,03% mujeres). Cuando fueron diagnosticados, la edad media fue de 55,75 años (DE ± 12,92), la media de HbA1C fue de 9,10% (DE ± 2,28). Hubo diagnóstico concomitante de hipertensión arterial o de dislipidemia en 27,13% y 52,40%, respectivamente. Al año de seguimiento, 57,76% de los sujetos alcanzó la meta de HbA1C ( 40 mg / dL), 24,31% para HDL-c en mujeres (>50 mg/dL), 48,24% para triglicéridos (<150 mg/dL), y 89,23% para presión arterial (<140/90 mmHg). Conclusiones: En este estudio en condiciones de la vida real, en adultos con DMT2 con un año de seguimiento, el logro de la meta de HbA1C (<7%) se alcanzó en el 58% de los pacientes. Si bien estos resultados son compatibles con los reportados en otros estudios de la región, se evidencia la oportunidad de mejorar el logro temprano de metas con el objetivo de optimizar los resultados a largo plazo.

Aim: To estimate the proportion of subjects with type 2 diabetes mellitus (T2DM) who attain therapeutic goal for HbA1C one year after diagnosis (early metabolic control). Methods: Retrospective review of medical records of adults cared for at 16 centers in nine Peruvian cities. Patients who received an initial diagnosis of T2DM and had at least one year of follow up were included. Metabolic goals were as defined by ADA 2018 standards. Results: 457 subjects were included (53,03% female). At diagnosis, mean age was 55,75 years (SD ± 12.92), mean HbA1C was 9,10% (SD ± 2,28). Concomitant hypertension or dyslipidemia were present in 27,13% and 52,40%, respectively. At one year follow up, 57,76% of subjects attained the goal for HbA1C ( 40 mg/dL), 24,31% for HDL-c in women (>50 mg/dL), 48,24% for triglycerides (<150 mg/dL), and 89,23% for blood pressure (<140/90 mmHg). Conclusions: In this real-life study of adults with T2DM with one year of follow up, metabolic control for HbA1C (<7%) was attained in 58% of subjects. While the results are compatible with those reported in other studies in the region, there is opportunity to further improve early treatment goal attainment to optimize long-term outcomes.

A 5-year follow up analysis of cases in a high school tuberculosis outbreak / 中国学校卫生

Objective@#To explore the effectiveness of preventive treatment for latent tuberculosis infection (LTBI) patients, so as to provide reference for the management and preventive treatment of clustered epidemic in schools.@*Methods@#Data came from the school tuberculosis outbreak of a boarding high school in Kaizhou District, Chongqing, which occurred between June 2017 and March 2018 among 2016 grade high school teachers and students for investigation and analysis. The total incidence, LTBI patients, and the incidence after preventive treatment for 5 years were followed up.@*Results@#A total of 34 cases of pulmonary tuberculosis from June 2017 to March 2018. A total of 1 357 individuals were screened for 6 concentrated contact screenings, with a confirmed tuberculosis rate of 2.43%, a tuberculosis skin test (TST) positive rate of 27.41%, and a strong TST positive rate of 7.39%. Among them, the confirmed tuberculosis rate and TST positive rate in the first case class were much higher than those in other classes, with statistically significant differences ( χ 2=286.30, 98.59, P ＜0.01). 88 cases of LTBI were found, with 31 cases receiving preventive treatment (35.23%), of which 28 completed preventive treatment (90.32%). After five years of follow-up, 73 cases of pulmonary tuberculosis were diagnosed in 2016 by the school senior high school, with a incidence rate of 0.98/10 2 (person/person years). Fifteen of the 88 LTBI patients were diagnosed with pulmonary tuberculosis, and the incidence rate was 3.33/10 2 (person/person years). The incidence rate of the preventive treatment group was 0.7/10 2 (person/person years)lower than that of the medical observation group 4.5/10 2 (person/person years), with a statistically significant difference ( χ 2=4.31, P ＜0.05).@*Conclusion@#The classes with higher TST positive rate and strong positive rate have higher incidence rate. Improving the preventive treatment rate of LTBI patients can effectively reduce the incidence rate of tuberculosis.

Prenatal diagnosis and pregnancy outcome of anomalous origin of one pulmonary artery branch from the aorta: analysis of 14 cases / 中华围产医学杂志

Objective:To summarize the prenatal diagnosis features, classification and pregnancy outcome of anomalous origin of one pulmonary artery branch from the aorta (AOPA).Methods:This study involved 14 cases who were prenatally diagnosed with AOPA in Guangzhou Women and Children's Medical Center between June 2016 and August 2022. Prenatal and postnatal echocardiographic features, postpartum diagnosis, surgical treatment and pregnancy outcome in these cases were summarized and analyzed by descriptive analysis.Results:Out of the 14 fetuses, there were seven fetuses with proximal-type AOPA (including three isolated AOPA, three Berry syndrome and one with interruption of the aortic arch, aorticopulmonary septal defect and ventricular septal defect) and another seven with isolated distal-type of AOPA. Among the seven cases of proximal-type AOPA, two were terminated and five were born alive. The postpartum diagnosis was consistent with the prenatal diagnosis in the five babies who later underwent surgical treatment with good outcomes. Among the seven cases of distal-type AOPA, one was terminated; two were initially diagnosed as AOPA in the neonatal period but then as unilateral absence of pulmonary artery (UAPA) due to tapering or closure of the ductus arteriosus during follow-up; the other four were confirmed with UAPA after delivery. All of the six neonates underwent surgical treatment with good outcomes.Conclusions:Prenatal diagnosis and classification of AOPA should be as accurate as possible. It is recommended that the distal-type of AOPA could be diagnosed as UAPA after delivery and treated according to UAPA. Both kinds of patients should be treated with surgery timely after delivery to ensure a good prognosis.

Objective:To analyze and summarize the imaging characteristics and clinical follow-up results of Ewing sarcoma of bone.Methods:The imaging data of 23 patients with Ewing sarcoma confirmed by pathology who treatment in Drum Tower Hospital Affiliated to Nanjing University School of Medicine from May 2010 to October 2021 were retrospectively analyzed, and clinical follow-up was performed.Results:Of the 23 patients with Ewing sarcoma of the bone in this group, a total of 18 patients had follow-up results and 5 cases were lost to follow-up. Of the 18 cases, 6 cases died and 12 cases survived. The main cause of death was lung metastasis. There were 27 lesions in total, femoral diaphysis was the most common site of the disease; bone structure destruction and soft tissue mass shadows could be seen in the images of each lesion. Periosteal reaction could be seen in most of the lesions (92.59%, 25/27). There were certain differences in signs of bone destruction and periosteal reaction between different bone types.Conclusions:The imaging of Ewing sarcoma of bone mainly manifests various types of bone destruction, soft tissue masses and periosteal reactions. Ewing sarcoma of bone is mainly bone marrow metastasis and lung metastasis, and lung metastasis is the main cause of death.

Clinical effects and mid-term follow-up analysis of para-split laminotomy for lumbar spinal canal tumors / 国际外科学杂志

Objective:To investigate the surgical outcome and prognostic factors of para-split laminotomy for removal of lumbar spinal canal tumors.Methods:Retrospectively review the clinical data of 35 patients suffering lumbar spinal canal tumors, who underwent the para-split laminotomy for tumor resection in Department of Neurosurgery, Clinical Medical College of Yangzhou University from October 2016 to August 2019, including 16 males and 19 females, and the age was(40.1±10.6)years. Intraoperative blood loss, operation time, tumor resection, tumor pathological results, perioperative complications were observed. Follow-up situations, including tumor recurrence, bony fusion of laminae and spinal stability. Follow-up using outpatient examination and telephone interview was performed by the end of August 2022. The JOA back pain scoring system was used to evaluate the neurological function of the spinal cord, and paired t-test were performed to compare the overall preoperative and postoperative spinal cord neurological function scores. Linear regression and multiple linear regression were used to analyze the prognostic factors. Measurement data of normal distribution were expressed as mean±standard deviation ( ± s), and the comparison before and after operation was performed by paired t-test. Mearsurement data of skewed distribution were expressed as M( Q1, Q3). Count data were expressed as cases. Results:The tumors of 35 patients were resected completely. The median blood loss was 100(75, 140)mL and the average operative duration was (181.1±42.7) min. The postoperative pathological results were as follows: 24 neurilemmomas, 6 meningiomas, 4 ependymomas and 1 neurofibroma. There were no surgery-related complications occurred. The postoperative follow-up ranged from 36 to 69 months, with no tumor recurrence or spinal instability, and bony fusion of laminae seen in some patients on CT imaging. The overall spinal cord neurological function scores of pre and post operation were(19.5±3.4)versus(25.4±2.2), Paired t-test analysis revealed a significant difference between the overall postoperative spinal cord neurological function scores and the preoperative scores, and the postoperative scores were better than the preoperative scores( P<0.05). Multiple linear regression analysis showed a positive correlation between preoperative JOA scores and postoperative JOA scores, and postoperative JOA scores has negative correlation with tumor volume and the age at the time of operation ( P<0.05). Conclusion:Para-split laminotomy with less damage to the posterior spinal structures can effectively improve the neurological function of the spinal cord and protect the stability of the lumbar spine in patients with lumbar spinal canal tumors, and the better the preoperative neurological function of the spinal cord, the better the prognosis of patients, and the smaller the tumor volume, the better the prognosis.

Follow-up study on newly diagnosed occupational pneumoconiosis patients in Guizhou Province, 2006-2021 / 中国职业医学

Objective To analyze the survival status, distribution characteristics and social security of newly diagnosed occupational pneumoconiosis patients in Guizhou Province from 2006 to 2021. Methods The newly diagnosed pneumoconiosis cases reported in Guizhou Province from 2006 to 2021 were collected from the “Occupational Diseases and Hazards Monitoring Information System” under “National Health Insurance Disease Prevention and Control Information System”. Telephone or face-to-face surveys were conducted to investigate these patients. Results A total of 12 413 newly diagnosed pneumoconiosis patients were reported in Guizhou Province from 2006 to 2021, with 11 192 cases included in the follow-up, and 10 631 cases were followed-up successfully. According to the follow-up study, 10 565 cases (accounting for 99.4%) were survived, and 66 cases (accounting for 0.6%) died. The number of pneumoconiosis showed an increasing trend followed by a sharp decline from 2006 to 2021, reaching its peak in 2016. The main industry of the newly pneumoconiosis cases was concentrated in the mining industry (accounting for 90.6%). The top three regions with surviving cases in the follow-up were Bijie City, Zunyi City, and Qiannan Prefecture, accounting for 34.0%, 25.4% and 12.0%, respectively. The main types of pneumoconiosis were coal workers' pneumoconiosis and silicosis, accounting for 67.1% and 30.8%, respectively. Most cases were in the age group of 50 to <60 years old, accounting for 59.1%, and the majority of the workers had worked in dusty environments for 5 to <25 years, accounting for 91.5%. In terms of social security, about 89.5% of cases were in the basic medical insurance for urban and rural residents which was the most popular social security. The employer's compensation rate was 67.7%, and the work-related injury insurance participation rate was 51.5%. Conclusion Pneumoconiosis cases in Guizhou Province exhibit significant regional disparities. It has a high concentration in the industry, a younger age profile, and limited social security coverage. It is necessary to strengthen the special management of dust and industry supervision in mining industry, intensify follow-up work for pneumoconiosis cases, reinforce the construction of pneumoconiosis rehabilitation station in key regions, and improve the quality of life of pneumoconiosis cases.

A follow up study of body fat distribution and blood pressure among 6-9 years old children in Beijing / 中国学校卫生

Objective@#To explore the association of body fat mass and distribution indices including fat mass percentage (FMP), visceral fat area (VFA) and percentage of trunk fat mass (%TFM) with blood pressure in children to inform early management of blood pressure in children.@*Methods@#Based on the Beijing Child Growth and Health Cohort in Shunyi District, lifestyle questionnaire survey, baseline and follow up physical examination were conducted among children from October to November 2018 and September 2020. Bioelectrical impedance analysis (BIA) was used to measure the body composition, and 1 098 participants with completed data were finally included.@*Results@#Both body fat indices and blood pressure increased with age in boys and girls. For FMP, VFA, and %TFM, no significant differences presented between sex at baseline, while FMP, VFA, and %TFM were significantly higher in boys than girls at follow up ( t=2.73, 3.76, 3.41, P <0.01). Before and after adjusting for age, height and lifestyles or not, linear mixed effect models showed longitudinal associations existing between body fat indices and blood pressure in both boys and girls ( β=0.64-3.48, P <0.05). The association coefficients of body fat indices with systolic blood pressure were ranked as %TFM>FMP>VFA in both boys and girls. The association coefficients of body fat indices with diastolic blood pressure were ranked sequentially as FMP>%TFM>VFA in boys, and VFA>FMP>%TFM in girls.@*Conclusion@#Longitudinal associations are observed between body fat indices and blood pressure in children. Primordial prevention of high pressure should pay attention on body fat distribution.

Bidirectional associations between cellular phone use behaviors and depressive symptoms in college students: a follow up study / 中国学校卫生

Objective@#The study aimed to describe the prevalence of mobile phone use and depressive symptoms and to examine the bidirectional associations between the two among college students, providinb evidence for mental health promotion among college students.@*Methods@#A longitudinal study with follow up at 6 month intervals was conducted in 1 135 students from 2 universities in Hefei, Anhui Province and Shangrao, Jiangxi Province who were selected between April and May 2019. The last follow up was conducted between April and May 2021 based on questionnaire survey, and 999 valid participants were obtained after matching. The self designed questionnaire was used to investigate the duration of cellular phone use and use of cellular phone functions among college students. The Self rating Questionnaire for Adolescent Problematic Mobile Phone Use (SQAPMPU) and the Patient Health Questionnaire-9 (PHQ-9) were used to assess cellular phone dependence and depressive symptoms among college students. Pearson correlation analysis was used to examine the correlation between cellular phone use behavior and depressive symptoms at baseline and 2 years later; linear regression model was used to analyze the linear association between cellular phone use behavior and depressive symptoms scores; autoregressive cross lagged model was used to analyze the bidirectional associations between cellular phone use behaviors and depressive symptoms among college students over time.@*Results@#The prevalence of mobile phone dependence and depressive symptoms among college students at baseline were 24.3% and 42.4%, respectively. The mean duration of mobile phone use among college students at baseline and the 2 year follow up were (2.84±0.90)h/d and (2.02±1.05)h/d, respectively; the mean scores of mobile phone dependence were (23.30±9.00) and (23.29±10.45), respectively; the mean scores of mobile phone function use were (30.12±6.66) and (29.12±7.27), respectively; and the mean scores of depressive symptoms were (4.51±4.76) and (2.61±4.40), respectively. Pearson correlation analysis showed there were significant positive correlations between duration of cellular phone use, cellular phone dependence, use of cellular phone functions at baseline or 2 years later and depressive symptoms 2 years later( r =0.08-0.50, P <0.05). Linear regression models showed a significant positive association between cellular phone dependence at baseline and depressive symptoms ( β=0.26, 95%CI =0.23-0.29) at baseline and 2 years later ( β=0.12, 95%CI =0.09-0.15). Autoregressive cross lagged models showed that cellular phone dependence at baseline positively predicted depressive symptoms 2 years later ( β =0.04) and depressive symptoms at baseline positively predicted cellular phone dependence 2 years later( β =0.23)( P <0.05).@*Conclusion@#There was a bidirectional association between cellular phone dependence and depressive symptoms among college students. Reducing cellular phone dependence is of positive significance for improving college students mental health.

Analysis of gene variation and long-term follow-up in children with phenylalanine hydroxylase deficiency diagnosed by newborn screening / 浙江大学学报·医学版

OBJECTIVES@#To retrospectively analyze the variation and characteristics of phenylalanine hydroxylase (PAH) gene, and to observe the long-term treatment effect and follow-up of newborns with PAH deficiency.@*METHODS@#Clinical data, treatment and follow-up results of 198 patients with PAH deficiency diagnosed by newborn screening in Jinan from 1996 to 2021 were collected. The genetic analysis of 55 patients with PAH deficiency diagnosed by newborn screening in Jinan and 213 patients referred from the surrounding areas of Jinan were summarized. Gene variations were checked by a customized Panel gene detection method. Blood phenylalanine-concentration and physical development indicators including height and weight were regularly monitored. Intellectual development was assessed using a neuropsychological development scale for patients aged 0-6 years and academic performance, and brain injury in patients was assessed using brain magnetic resonance imaging.@*RESULTS@#c.728G>A, c.158G>A, c.721C>T, c.1068C>A, c.611A>G variations were common in PAH gene. The genotype of c.158G>A variation is compound heterozygous variation, with mainly a mild hyperpheny-lalaninemia. 168 patients with PAH deficiency who were followed-up regularly had normal physical development without dwarfism or malnutrition. Among the 33 preschool patients who underwent mental development assessment, 2 were mentally retarded and the initial treatment age was older than 6 months. Nine patients with an average age of (17.13±2.42) years completed brain magnetic resonance imaging, one case was normal, and 8 cases were abnormal. There were patchy or patchy hyperintense foci near the bilateral lateral ventricles on T2WI, and the intellectual development was normal. Compared with the other eight patients, the blood phenylalanine concentration of the normal child was better and stably controlled within the ideal range.@*CONCLUSIONS@#c.728G>A, c.158G>A, c.721C>T, c.1068C>A, c.611A>G variations were common in PAH gene. After standardized treatment, most patients with PAH deficiency diagnosed by screening can obtain normal growth and intellectual development in adolescence, but there are different degrees of organic lesions in the cerebral white matter.
