MR Imaging in Eclampsia

Background : The aim of this study is to determine the distribution and nature of Cranial MRI findings in eclamptic patients, and to correlate them with clinical and laboratory data. Materials and Methods : This study was conducted in the Department of Obstetrics and Gynecology in Sri Ramachandra Institute of Higher Education and Research. A total number of 35 Eclamptic patients were included in this study and they were analyzed retrospectively. Laboratory parameters, Blood Pressure and Cranial MRI was performed for all and the same were analyzed statistically. Results : Out of 35 Eclamptic patients, MR Imaging was normal in 6 patients. Among the 29 patients with abnormal MRI, Cortical-subcortical Lesion, appeared iso/hypo-intense in T-1 weighted images and hyper intense in T-2 weighted images. In most of the patients, occipital lobe was involved followed by involvement of other lobes such as Parietal, Frontal, Temporal, Basal Ganglia and Cerebellum. When patients with and without positive MRI findings were compared regarding clinical features such as Headache, Blurred Vision, Nausea and Vomiting, Epigastric Pain, Loss of Consciousness, Reduced Urine Output there was no statistically significant difference between the two groups. Similarly, there was no statistical difference in mean arterial pressures between MRI positive and MRI negative patients (p=0.218) however, it was found that those with MR imaging positive features had a higher Blood Pressure than those with MRI negative findings. Among the laboratory parameters, in the patients with abnormal MRI findings Fibrinogen was found to be significantly low than those with normal MRI findings (p=0.0002).

Androcentric club narratives around spanish football: press coverage of athletic bilbao's men and women teams / Narrativas de clube androcêntricas no futebol espanhol: cobertura de mídia impressa das equipes de homens e mulheres do athletic bilbao / Narrativas de club androcéntricas en el fútbol español: cobertura de prensa de los equipos de hombres y mujeres del athletic bilbao

Abstract This research focuses on the androcentric hierarchy of identity narratives in football. We explore how such discourses are planned in terms of gender at The club level. We enquire into the presence of and the role played by women footballers in the narrative construction of clubs as portrayed in media outlets. Our case study focuses on Athletic Bilbao, a pioneering club in women's football in Spain. The methodology used is based on content analysis, covering three full seasons (2018-19, 2019-20 and 2020-21) of the front pages of four newspapers (As, Mundo Deportivo, El Correo and Deia). We found a sexist relational system with two major categories - sequential and normative - in the construction and reproduction of information. We point out the prevalence of sporting narratives focused on men and, in relational terms, the invisibility and, in a best-case scenario, the peripheralization of information about women.

Resumo Esta pesquisa se concentra na hierarquia androcêntrica das narrativas identitárias no futebol. Explora-se como esses discursos são planejados em termos de gênero e ao nível de clube. Investiga-se a presença e o papel desempenhado pelas jogadoras na construção narrativa dos clubes por meio da mídia. O nosso caso de estudo é o Athletic Bilbao, um clube pioneiro no desenvolvimento do futebol feminino na Espanha. Metodologicamente, foi feita uma análise de conteúdo das capas de quatro jornais espanhóis (As, Mundo Deportivo, El Correo, Deia) durante três temporadas completas (2018-19, 2019-20, 2020-21). Um sistema relacional sexista foi observado, sobretudo através de duas grandes categorias - sequencial e normativa - na construção e reprodução informativa. A onipresença das narrativas em torno das práticas esportivas dos homens é documentada. Em termos relacionais, a informação sobre as mulheres é invisível e, no melhor dos casos, periférica.

Se subraya la omnipresencia de las narrativas alrededor de las prácticas masculinas. En términos relacionales, se invisibiliza y, en el mejor de los casos, se periferiza la información sobre las mujeres.

Maternal A90V mutation in the PreS1 gene of sub-genotype C2 hepatitis B virus is associated with intrauterine transmission

ABSTRACT PreS/S gene mutations could impact virus secretion, infection and immune evasion. However, the relationship between PreS/S mutations and intrauterine transmission has not yet been clarified. Thus, we aimed to explore the associations between PreS/S gene mutations of HBV isolated from mothers and intrauterine transmission. We analyzed the mutations of PreS/S regions of the HBV genome in mothers with HBV DNA levels ≥ 106 IU/mL whose neonates experienced HBV intrauterine transmission (transmission group, GT) and those whose neonates did not experience intrauterine transmission (control group, GC) analyzed using clone-based sequencing. In total, 206 sequences were successfully amplified, including 98 sequences (from 21 mothers) from GT and 108 sequences (from 20 mothers) from GC of genotype C for mutational analysis. Among the 1203 nucleotides of PreS/S regions, there were 219 (18.20%) base substitutions, of which 103 (47.03%) base mutations caused amino acid changes. F80S, A90V and I68T were mutation hotspots. Mothers in GT had a higher mutation rate of A90V in the PreS1 gene than mothers in GC. The A90V mutation increased the risk of HBV intrauterine transmission after adjusting the maternal age and the mode of delivery (OR = 6.23, 95% CI: 1.18-32.97). Moreover, the area under the ROC curve (AUC) for intrauterine transmission due to A90V and a combination of A90V with the mode of delivery were 0.723 (95% CI: 0.575 to 0.891, P = 0.011) and 0.848 (95% CI: 0.723 to 0.972, P < 0.001), respectively. Mothers with the A90V mutation in the PreS1 gene may be a potential risk factor for HBV intrauterine transmission.

DELAYED PRESENTATION OF POSTERIOR REVERSIBLE ENCEPHALOPATHY SYNDROME IN POSTPARTUM PERIOD

Posterior reversible encephalopathy syndrome (PRES) is an uncommon neurological entity which presents with diverse neurological symptoms ranging from headache, seizure, visual symptoms with altered consciousness and focal signs. The hallmark of this condition is its reversibility. The etio- pathogenesis is attributed to vasogenic cerebral oedema seen in occipital and parietal lobes of brain. We hereby present this case of a multiparous lady presenting with altered sensorium postpartum. Characteristic findings on imaging helped us to form the diagnosis of PRES in this patient

Imaging manifestations of central nervous system complications after heart transplantation / 器官移植

Heart transplantation is the main treatment of end-stage heart failure. With the advancement of heart transplantation and rational use of postoperative immunosuppressants, the survival rate of recipients has been gradually enhanced. However, a variety of central nervous system complications may still occur following heart transplantation, including immunosuppressant-associated neurotoxicity, epilepsy, stroke, encephalopathy, central nervous system infection and de novo malignant tumors in the central nervous system. These complications will severely affect the quality of life of heart transplant recipients. Consequently, prompt imaging diagnosis plays a significant role in the prevention and treatment of central nervous system complications. In this article, main imaging manifestations of central nervous system complications after heart transplantation were reviewed, aiming to provide reference for prompt diagnosis and differential diagnosis of complications, guide clinical treatment and management, and improve the long-term prognosis of the recipients.

Objective To analyze the sequence of Pre-S gene in asymptomatic chronic HBV carriers (ASCs) with low-level HBsAg.Methods The serum samples were collected from 654 ASCs in the First Affiliated Hospital of Zhejiang University School of Medicine , Hangzhou Sixth People’s Hospital and the 903th Hospital of PLA.According to the level of HBsAg , ASCs were divided into low-level HBsAg group (≤10 IU／mL ) and high-level HBsAg group (＞10 IU／mL ).The pre-S／S gene amplification and sequencing were performed in 138 ASCs with low-level HBsAg and 100 age-matched ASCs with high-level HBsAg.A phylogenetic tree was constructed to determine the genotype , based on the successful sequencing results of Pre-S gene in the high level HBsAg group , the Pre-S gene reference sequences of the main ASCs genotypes in Eastern China were established.The sequence of Pre-S gene in low-level HBsAg group was analyzed and compared with the reference sequences.SPSS 12.01 statistical software was used to analyze the data.Results Sixty-three cases of Pre-S／S were successfully sequenced in 138 ASCs of low-level HBsAg group, including 52 cases of B genotype and 11 cases of C genotype.Among the 100 cases of high-level HBsAg group, 94 cases of Pre-S／S were successfully sequenced , including 48 cases of B genotype and 46 cases of C genotype.The sequence analysis indicated that in the B genotype , 81 amino acid mutation sites were found in the Pre-S protein of the low-level HBsAg group, including 4 significant mutations: F56I／V, T76A／N／P in the Pre-S1 region, P15L／S／T and Y21T／F／H／N in the Pre-S2 region; while 47 amino acid mutation sites were found in Pre-S protein of high-level HBsAg group, including 3 significant mutations :L34F, V49A and P59S／L in Pre-S1 region.The total number of amino acid mutation sites in the low-level HBsAg group of B genotype was higher than that of the high-level HBsAg group (χ2 ＝14.008, P＜0.05). In the C genotype, 19 amino acid mutation sites were found in the Pre-S protein of the low-level HBsAg group, including 3 significant mutations : W66V／G and A79V in the Pre-S1 region,V32A in the Pre-S2 region; while 39 amino acid mutation sites were found in Pre-S protein of the high-level HBsAg group, including 2 significant mutations: A79V in Pre-S1 region and T49I in Pre-S2 region.The total number of amino acid mutation sites of Pre-S protein in the C genotype was significantly different between the two groups (χ2 ＝7.571, P＜0.05).Conclusion Significant mutations in Pre-S gene may be associated with the persistent expression of low-level HBsAg in ASCs.

Efficacy of pulmonary surfactant combined with caffeine citrate on neonatal respiratory distress syndrome treated with synchronized nasal intermittent positive pressure ventilation / 中国小儿急救医学

Objective To investigate the clinical effects of pulmonary surfactant ( PS) combined with caffeine citrate on neonatal respiratory distress syndrome(NRDS) treated with synchronized nasal inter-mittent positive pressure ventilation(SNIPPV). Methods We collected and analyzed 99 neonates who were diagnosed with NRDS and required SNIPPV treatment from January 2016 to June 2019 in NICU of Shengjing Hospital of China Medical University. According to the different treatment,they were divided into PS+ cit-rate caffeine combination group and control group. The control group(53 neonates)was treated by PS alone. The combination group(46 neonates)was treated with PS combined with caffeine citrate. The indexes of vent-ilator time,the time of using oxygen,length of hospital stay and complications were compared between the two groups. Results The indexes of ventilator time,the time of using oxygen and length of hospital stay of combination group were significantly shorter than those of the control group. The differences were statistically significant(P<0. 05). However,the incidences of ventilator associated pneumonia,gastrointestinal dysfunc-tion,arrhythmia and other complications were not significantly different between the two groups(P>0. 05). Conclusion PS combined with caffeine citrate in the treatment of NRDS with SNIPPV could effectively im-prove the pulmonary function of infants. It could improve the neonatal survival rate and reduce complications. It is worth to be recommended.

Síndrome de encefalopatía posterior reversible en lupus eritematoso sistémico / Reversible posterior encephalopathy syndrome in systemic lupus erythematosus

El síndrome de encefalopatía posterior reversible (PRES) es una condición reversible, poco conocida en el lupus eritematoso sistémico (LES) que puede semejar al lupus neuropsiquiátrico. Las manifestaciones de PRES son cefalea, convulsiones, alteración del nivel de conciencia y amaurosis. En la mayoría de los casos, la TC (tomografía computarizada) del cerebro muestra lesiones hipodensas en el lóbulo parieto-occipital. Aunque este síndrome es poco común, el reconocimiento rápido y preciso permite un tratamiento temprano con resultados favorables. Presentamos un caso clínico de una paciente con debut de LES posterior a episodio de eclampsia, y que durante el puerperio tardío presenta hipertensión sostenida asociada a convulsiones y deterioro del nivel de conciencia en contexto de PRES

Posterior reversible encephalopathy syndrome (PRES) is a poorly recognized and reversible condition in systemic lupus erythematosus (SLE) that could mimic neuropsychiatric lupus. The manifestations of PRES are headache, seizures, altered level of consciousness and blindness. In most cases, computed tomography of the brain shows hypodense lesions in the parieto-occipital lobe. Although this syndrome is rare, rapid and accurate recognition allows early treatment with favorable results. We present a case report of a patient with the onset of SLE following the episode of eclampsia, and who during the late puerperium presented sustained hypertension associated with seizures and deterioration of the level of consciousness in the context of PRES.

Posterior reversible encephalopathy syndrome in preeclampsia – A prospective study

Background: Posterior reversible encephalopathy syndrome (PRES) which is a clinic-radiological manifestation sometimes also seen in PE and eclampsia. Materials and methods: 30 cases of preeclampsia or eclampsia cases that had CNS manifestations were studied with MRI before and after neurological recovery. All 100% cases had prompt and total recovery in 1-2 weeks. Results: Headache, Blurring of vision, and vomiting were the common clinical manifestations. Parieto-occipital lobes were commonest sites of cerebral involvement. Conclusion: Most patients with PRES have a suggestive combination of symptoms MRI is crucial for diagnosing, monitoring the course, and assessing treatment effectiveness. Repeated cerebral imaging helps to support the diagnosis. Early recognition and resolution of the underlying cause is the keystone of management.

The “premonitory symptoms” of eclampsia can be interpreted as actual symptoms of cerebral involvement within the posterior reversible leukoencephalopathy syndrome, and eclampsia as a severe symptom of the same syndrome. Objective: To review the characteristics of women with eclampsia in a national hospital, with emphasis on the associated neurological manifestations. Design: Case series. Institution: Hospital Nacional Daniel Alcides Carrion (HNDAC), Lima, Peru. Patients: Women with eclampsia. Methodology: Study of all patients with eclampsia over a period of 5 years and 6 months. Eclampsia cases that occurred outside the institution or with insufficient data were excluded. Main outcome measures: General characteristics, associated symptoms, complications and laboratory values in eclamptic patients. Results: Thirty-nine cases were reported. The incidence of eclampsia in pregnant women was 0.19%. The mean age was 21 years; 75.8% of the women were primiparous and 44.4% were less than 34 weeks pregnant. 69.7% of them were diagnosed before delivery; 51.5% had blood pressure above 160/110 mmHg and 12.1% had no hypertension. 93.9% presented symptoms, mainly headache (87.9%), as well as visual (27.2%) and auditory (12.1%) disturbances. Two patients had headache and normal blood pressure, and 2 cases were asymptomatic. Complications were: sensory alterations, abruptio placentae (15.2%), HELLP syndrome (15.2%) and difficult-to-control hypertension (39.4%). There were neither maternal nor perinatal deaths. Conclusions: The neurological manifestations that precede eclampsia are variable and do not have a constant correlation with the severity of maternal hypertension.

HBV genotyping based on key epitopes of PreS1 antigen and its correlation with genotyping by full-length PreS1 sequencing / 中华肝脏病杂志

Objective@#The aim was to investigate the genotype distribution of two major epitopes of large surface protein (PreS1) of hepatitis B in Chinese patients and to explore the association between the genotypes of these two epitopes, and to determine whether PreS1 full-length genotype could be revealed according to the polypeptide sequence of key epitopes. @*Methods@#HBV DNA was extracted from the serum of patients for PCR amplification. 278 samples amplified successfully were sequenced and compared with the known HBV sequences in Genbank to determine the two key epitopes of HBV PreS1 genotype (amino acid epitope 21-47 and 94-117, abbreviated as P21 and P94) and PreS1 full-length genotypes. The correlation among three genotyping approaches was analyzed by Cohen’s kappa coefficient to verify the consistency between the key-epitope genotyping and the full-length preS1 genotyping. @*Results@#232 samples were successfully sequenced. The genotyping based on the kind of P21 epitope protein sequence, 201 cases for genotype C, 23 cases for genotype B and 8 cases for uncertain genotypes and genotyping based on the form of P94 epitope protein sequence, 199 cases for genotype C, 25 cases for genotype B and 8 cases for indeterminate genotypes. Lastly, the genotyping based on sequence of the full-length PreS1 sequence, 207 and 25 cases for genotype C and B. P21 or P94 epitope genotyping and PreS1 full length genotyping were highly consistent, respectively, 96.55% and 96.12%, and the two epitopes (P21and P94) genotyping have parallel consistency (93.10%). @*Conclusion@#In this study, an innovatively genotyping method based on the amino acid sequence of key epitopes was proposed. The genotypes of HBV in china were mainly B and C genotypes, and the genotypes of key conserved epitopes of HBV PreS1 were highly consistent with the full-length genotyping ( > 96%). Moreover, genotyping with one or two key epitopes can be used in place of the full-length genotyping.

Conclusions: In our study, this disease was much more prevalent in girls, on the other hand in regard to the clinical manifestations according to diagnostic criteria of EULAR / PRINTO / Pres, our population behaved in a similar way to other studies.

Clinical observation of treatment used for expiration control device with mask for chronic obstructive pul-monary disease / 实用医学杂志

Objective To test the clinical effects of the expiration control device with mask in the treat-ment of chronic obstructive pulmonary disease. This device developed by the author. Methods A total of 102 pa-tients were treated by the device. Among them ,50 patients received positive end-expiratory pressure and 52 with expiratory flow retard and blocked function. Differences in carbon dioxide partial pressure(PaCO2),oxygen partial pressure(PaO2)and pH of the arterial blood gas analysis were compared ,as well as differences in forced vital ca-pacity(FVC),forced expiratory volume for1 sec(FEV1),tidal volume(VT)of pulmonary function before and af-ter treatment. Results (1) In the positive end-expiratory pressure group ,there were significant differences of FVC,FEV1 and VT before and after treatment(2.95 ± 0.32)L vs(3.22 ± 0.35)L,(1.88 ± 0.17)L vs(2.00 ± 0.15)L,(335.28 ± 43.59)mL vs(364.64 ± 44.28)mL,(P<0.01)differences of PaCO2,PaO2 and pH before and after treatment had statistical significance(50.42 ± 4.77)mmHg vs(48.42 ± 3.76)mmHg,(65.42 ± 4.60)mmHg vs (68.50 ± 4.69)mmHg,(7.35 ± 0.030)vs(7.37 ± 0.037)(P<0.05).(2)In the expiratory flow retard and blocked group,differences of FVC,FEV1andVT before and after treatment had statistical significance(2.93 ± 0.22)L vs (3.10 ± 0.27)L,(1.83 ± 0.14)L vs(1.91 ± 0.16)L,(335.48 ± 44.16)mL vs(362.46 ± 38.66)mL(P<0.05), differences of PaCO2,PaO2 and pH before and after treatment had statistical significance(52.39 ± 3.37)mmHg vs (50.06 ± 3.92)mmHg,(68.05 ± 3.80)mmHg vs(68.99 ± 4.57)mmHg,(7.34 ± 0.035)vs(7.37 ± 0.036)(P<0.05). Conclusion This device can improve the ventilation function in patients with COPD. It is easy to use ,safe and effective,with high clinical application value.

The application value of enzyme linked immunosorbent assay for hepatitis B PreS1 antigen and antibody in the diagnosis of hepatitis B / 中国生化药物杂志

Objective To explore the application value of enzyme linked immunosorbent assay for detection of hepatitis B PreS1 antigen and antibody in the diagnosis of hepatitis B.MethodsSeveral common patterns in the results of hepatitis Btwo halfcheck were selected from August 2014 to August 2016 for the sample, the use of hepatitis Btwo half7 commonly used detection model for 140 cases of PreS1 antigen, antibody detection.Enzyme linked immunosorbent assay for detection of PreS1 antigen and antibody.ResultsIn patients with HBeAg in PreS1 antigen positive rate was 87.5%, in patients with positive PreS1 antigen positive rate was 8.6%, HBsAg, HBcAb in patients with positive PreS1 antigen positive 13.3%, in a pure HBsAg in patients with positive PreS1 antigen 4.3%.There was no significant difference in the total positive rate of HBV-DNA and the total positive rate of PreS1, and the total coincidence rate was higher.PreS1 antigen positive correlated with HBsAg, HBeAg and HBcAb positive(P<0.05), and has nothing to do with HBsAb, HBeAb positive.ConclusionHepatitis B PreS1 antigen and antibody detection, can effectively complement the diagnosis of hepatitis B, early detection of hepatitis B infection.
