RESUMO
Resumen Introducción : El cáncer colorrectal (CCR) es un pro blema de salud a nivel global. En el sector público de Bahía Blanca, el tamizaje de CCR es oportunista, por solicitud de sangre oculta en materia fecal (SOMF). El objetivo de este trabajo es describir el acceso al tamiza je de CCR de la población con cobertura pública exclu siva que reside en el área programática 2 de la ciudad entre 2019 y 2021, y relevar las barreras y facilitadores que lo determinan. Métodos : Se estimó la tasa de uso anual y acumula da de SOMF. Las barreras y facilitadores se relevaron a través de 41 entrevistas individuales semi-estructuradas al personal de salud del área programática, el Hospital Municipal, Secretaría de Salud y usuarios/no usuarios del sistema. Resultados : La tasa acumulada de uso de SOMF en el período fue 4.8%. Entre las barreras al tamizaje per cibidas se destacan: la dificultad en el acceso a estudios de mayor complejidad para pacientes con SOMF+, el desconocimiento y falta de percepción del CCR como un problema de salud por parte de la población y la baja adherencia de los profesionales a los lineamientos. La territorialidad y el vínculo de los centros de salud con la población, y la predisposición de usuarios y profesio nales a incorporar el tamizaje surgen como facilitadores del mismo. Conclusiones : El relevamiento de las barreras orien tará el diseño de estrategias adaptadas al contexto que permitan en el futuro reforzar el tamizaje.
Abstract Introduction : Colorectal cancer (CRC) is a global health problem. In the public sector of Bahía Blanca, CRC screening is opportunistic, through the request of fecal occult blood test (FOBT). The objective of this study is to describe access to CRC screening for the population with exclusive public coverage residing in the program matic area 2 of the city between 2019 and 2021, and to identify the barriers and facilitators that determine it. Methods : The annual and cumulative usage rate was estimated based on the number of patients who requested FOBT. The barriers and facilitators were studied through 41 semi-structured individual inter views to healthcare staff from the area, the Municipal Hospital, Health Secretariat and users/non-users of the system. Results : The cumulative usage rate of FOBT during the period was less than 5%. Among the perceived bar riers to screening, we found: the difficulties in accessing more complex studies for patients with positive FOBT, the lack of population awareness and perception of CRC as a health problem, the low adherence of professionals to guidelines. The territoriality and link of health centers with the population, as well as the willingness of users and professionals to incorporate screening, emerge as facilitators. Conclusion : The identification of barriers and facilita tors will allow the design of context-adapted strategies that will strengthen screening in the future.
RESUMO
【Objective】 To investigate the status of occult hepatitis B virus infection(OBI) among blood donors in Quzhou, Zhejiang, and to analyze the mutation of S region in blood donors with anti-HBc+ alone and non anti-HBc+ alone. 【Methods】 The OBI samples were screened by ELISA and NAT; the HBV DNA was amplified and sequenced; 20 anti-HBc+ alone and 25 not anti-HBc+ alone samples were obtained. 【Results】 The detection rate of OBI in Quzhou was 0.10%(155/161 045), and the positive rate of anti-HBc was 74.19%(115/155). The detection rate of OBI increased with the age of blood donors(P<0.05), but was not related to gender. The positive rate of anti-HBc+ alone was 22.58%(35/155), and that of not anti-HBc alone was 51.61%(80/155). Among the 45 OBI sequencing samples, the proportion of B and C genotype was 73.33%(33/45) and 20.00%(9/45), respectively. The mutation sites of blood donors in the anti-HBc+ alone group were more than those in the not anti-HBc+ alone group, and the mutation rates of S114T and V168A on MHR were significantly different(P<0.05). 【Conclusion】 The genotype of OBI infection in Quzhou is mainly type B. The mutation sites of blood donors with anti-HBc+ alone are higher than those with not anti-HBc+ alone, which may be more suitable as one of the OBI screening indicators.
RESUMO
【Objective】 To analyze the correlation of HBV serological characteristics between non-reproducible reactivity (NRR) samples and occult hepatitis B virus infection (OBI) samples for blood screening. 【Methods】 A total of 144 samples with negative ELISA (HBV, HCV and HIV test) results and reactive nucleic acid tests(NAT) were collected from January 2021 to January 2023 in Anhui Blood Center, including 92 reactive samples by TMA method (combined ID-NAT) and 52 HBV DNA reactive samples by PCR method (ID-NAT). Supplementary differential testing and ID-NAT by PCR were performed on the reactive samples of the combined ID-NAT, samples that were non-reactive by both differential testing and ID-NAT by PCR were included in the NRR group, and samples that were reactive for HBV DNA detected by either method were included in the OBI group. Supplemented with HBsAg, anti-HBs, HBeAg, anti-HBe and anti-HBc tests, the differences in serological pattern and positive rate between NRR samples and OBI samples were analyzed. 【Results】 A total of 53 samples were negative for differential testing and ID-NAT and were included in the NRR group, 91 samples were detected as HBV DNA reactive in either method and were included in the OBI group. HBsAg and HBeAg were not detected by serological testing in either group. The detection rates of anti-HBs, anti-HBc and anti-HBe in the NRR group and the OBI group were 64.15% vs 47.25%, 86.79% vs 94.51%, 35.85% vs 52.75%, respectively. Comparison of serological patterns between the two groups: the most frequent pattern in the NRR group was anti-HBs (+ ) and anti-HBc (+ ) (32.08%), and the most frequent pattern in the OBI group was anti-HBe (+ ) and anti-HBc (+ ) (37.36%). 【Conclusion】 There were differences in some of the test results between the NRR samples and the OBI samples in HBV serological testing, and higher anti-HBc positive rate in the NRR samples suggests a higher possibility of HBV infection.
RESUMO
Objective: Colonoscopy is useful in diagnosing intestinal tuberculosis. However, the terminal ileum is generally not examined during routine colonoscopy. Therefore, even with colonoscopy, the diagnosis can be missed in patients with lesions confined to the terminal ileum. Herein, we report the case of an asymptomatic patient with intestinal tuberculosis, in whom a colonoscope insertion into the terminal ileum led to the diagnosis.Patient: An asymptomatic 71-year-old man visited our hospital for a colonoscopy after a positive fecal occult blood test.Results: Colonoscopy revealed diffuse edematous and erosive mucosa in the terminal ileum. Mycobacterium tuberculosis was detected by polymerase chain reaction and culture of biopsy specimens from the erosions, leading to the diagnosis of intestinal tuberculosis. The patient was treated with antitubercular agents for 6 months, and a follow-up colonoscopy revealed healing of the lesions.Conclusion: Asymptomatic intestinal tuberculosis may occasionally be detected on colonoscopy following a positive fecal occult blood test and is sometimes confined to the terminal ileum. Therefore, clinicians should consider intestinal tuberculosis in the differential diagnosis of the causes of positive fecal occult blood test results and perform colonoscopies, including observation of the terminal ileum.
RESUMO
Abstract Objective Cutaneous Squamous Cell Carcinoma (cSCC), a tumor with a significantly increasing incidence, is mostly diagnosed in the head region, where tumors have a worse prognosis and a higher risk of metastases. The presence of metastases reduces specific five-year survival from 99% to 50%. As the risk of occult metastases does not exceed 10%, elective dissection of the tributary parotid and neck lymph nodes is not recommended. Methods We retrospectively analyzed a group of 12 patients with cSCC of the head after elective dissections of regional (parotid and cervical) nodes by means of superficial parotidectomy and selective neck dissection. Results We diagnosed occult metastases neither in the cervical nor parotid nodes in any patient. None were diagnosed as a regional recurrence during the follow-up period. Conclucion Our negative opinion on elective parotidectomy and neck dissection in cSCC of the head is in agreement with the majority of published studies. These elective procedures are not indicated even for tumors showing the presence of known (clinical and histological) risk factors for lymphogenic spread, as their positive predictive value is too low. Elective parotidectomy is individually considered as safe deep surgical margin. If elective parotidectomy is planned it should include only the superficial lobe. Completion parotidectomy and elective neck dissection are done in rare cases of histologically confirmed parotid metastasis in the parotid specimen. Preoperatively diagnosed parotid metastases without neck involvement are sent for total parotidectomy and elective selective neck dissection. Cases of clinically evident neck metastasis with no parotid involvement, are referred for comprehensive neck dissection and elective superficial parotidectomy. The treatment of concurrent parotid and cervical metastases includes total conservative parotidectomy and comprehensive neck dissection. Level of evidence How common is the problem?

RESUMO
ABSTRACT Background: Functional constipation and enuresis frequently coexist. Constipation treatment often results in resolution or improvement of the enuresis. However, besides the classical presentation, patients can present with occult constipation (OC) diagnosed in complementary evaluation; in addition, semi-occult constipation (SOC) can be detected by means of a detailed questionnaire. Objective: To quantify OC and SOC frequency in children with monosymptomatic or non monosymptomatic enuresis (MNE or NMNE). Methods: Otherwise healthy children/adolescents, with enuresis refractory to behavioral therapy and denying constipation after simple questions, answered a structured bowel habit questionnaire and were submitted to a plain abdominal radiological exam. Constipation was classified considering the Boston diagnostic criteria (to allow diagnosis at initial stages), and fecal loading in the X-ray quantified ≥10 by the Barr score. Children with constipation received a standardized treatment (except 26 "pilot" children). Results: Out of 81 children, 80 aged 9.34±2.07 years, 52.5% male, were diagnosed with constipation: 30 OC, 50 SOC; 63.75% had MNE, 36.25% NMNE (six NMNE without behavioral therapy). Demographic data and the Barr score were similar for OC and SOC, but SOC children experienced significantly more constipation complications (retentive fecal incontinence and/or recurrent abdominal pain). Not showing the Bristol Stool Scale (BSS) to 24 "pilot" children, or absence of constipation symptoms accompanying BSS predominantly type 3, in 13 children, did not significantly impact the detection of constipation by the Barr score. Children identifying BSS 3 or ≤2 had similar results. Twenty-eight children, with adequate follow-up after treatment, improved or recovered from constipation at 44 of their 52 follow-up visits. Conclusion: In patients with MNE or NMNE refractory to behavioral therapy, and who initially denied constipation after simple questions, a detailed questionnaire based on the Boston diagnostic criteria detected SOC in 61.7%, and the radiological Barr score revealed fecal loading (OC) in 37.0% of them.
RESUMO Contexto: Constipação funcional e enurese frequentemente coexistem. Tratamento da constipação geralmente resulta em cura ou melhora da enurese. Entretanto, além da apresentação clássica, pode ocorrer constipação oculta (CO), diagnosticada por exame subsidiário; ademais, ao aplicar questionário detalhado, pode-se detectar constipação semioculta (CSO). Objetivo: Obter as frequências de CO e CSO em crianças com enurese mono- ou não monossintomática (EMN ou ENMN). Métodos: Crianças/adolescentes saudáveis, exceto por enurese refratária à terapia comportamental, e que negavam constipação após perguntas simples, respondiam a questionário estruturado sobre hábito intestinal, e realizavam radiografia simples de abdômen. A constipação foi classificada considerando os critérios diagnósticos de Boston (que permitem diagnóstico em fases iniciais) e retenção fecal na radiografia quantificada ≥10 pelo escore de Barr. As crianças com constipação receberam tratamento padronizado (exceto 26 crianças "piloto"). Resultados: Das 81 crianças, 80 com idade 9,34±2,07 anos, 52,5% masculinas, foram diagnosticadas com constipação: 30 CO, 50 CSO; 63.75% tinham EMN, 36.25% ENMN (6 ENMN sem terapia comportamental). Os dados demográficos e o escore de Barr foram semelhantes para CO e CSO, mas as crianças com CSO apresentaram significativamente mais complicações de constipação (incontinência fecal retentiva e/ou dor abdominal recorrente). A não apresentação da Escala Fecal de Bristol (EFB) para 24 crianças "piloto", ou ausência de sintomas de constipação acompanhando EFB predominantemente do tipo 3, em 13 crianças, não teve impacto significativo na detecção de constipação pelo escore de Barr. Crianças que identificaram EFB 3 ou ≤2 tiveram resultados semelhantes. Vinte e oito crianças, com acompanhamento adequado após o tratamento, melhoraram ou se recuperaram da constipação em 44 de seus 52 retornos. Conclusão: Em pacientes com EMN ou ENMN refratária à terapia comportamental, e que inicialmente negavam constipação após perguntas simples, questionário baseado nos critérios diagnósticos de Boston detectou CSO em 61.7%, e o escore radiológico de Barr revelou retenção fecal (CO) em 37% deles.
RESUMO
Introducción: El neumotórax oculto (NTXO) se encuentra hasta en el 15% de los traumatismos torácicos. Existen antecedentes del manejo conservador de esta patología (sólo observación), aunque su práctica continúa siendo discutida, especialmente, en traumatismos penetrantes. El objetivo de este trabajo es describir nuestra experiencia en el manejo conservador del NTXO. Materiales y Método: Estudio de cohorte retrospectivo realizado durante un período de 3 años en un Hospital de Trauma nivel I. Se incluyeron pacientes con traumatismo torácico (cerrado o penetrante) con NTXO. Se dividieron en dos grupos (conservados o drenados), realizándose una comparación de su evolución. Resultados: En 3 años fueron admitidos con traumatismo torácico 679 pacientes. De 93 pacientes con NTXO, 74 (80%) fueron conservados inicialmente y 19 (20%) tratados con drenaje pleural. Dos (3%) presentaron progresión del neumotórax en el seguimiento radiológico (conservación fallida). No se registraron complicaciones relacionadas con la ausencia de drenaje pleural. Las complicaciones y estancia hospitalaria fueron menores en el grupo de manejo conservador. Conclusión: Pacientes con NTXO por traumatismo de tórax (cerrado o penetrante), sin requerimiento de ventilación asistida y hemodinámicamente estables, pueden manejarse de manera conservadora con un monitoreo cercano durante 24 horas en forma segura, con menor tasa de complicaciones y de estancia hospitalaria.
Background: Occult pneumothorax (OPTX) is found in up to 15% of chest injuries. There is a history of conservative management of this pathology (only observation), although its practice continues to be discussed, especially in penetrating trauma. The objective of this paper is to describe our experience in the conservative management of OPTX. Materials and Method: Retrospective cohort study conducted over a 3-year period at a level I Trauma Center. Patients with thoracic trauma (blunt or penetrating) with OPTX were included. They were divided into two groups (preserved or drained) comparing their evolution. Results: Over a 3-year period 679 patients were admitted with chest trauma. From 93 patients with OPTX, 74 (80%) were initially preserved and 19 (20%) drained. Two patients (3%) presented pneumothorax progression in the follow-up imaging. There were no complications related to the absence of pleural drainage. Complications and hospital stay were lower in the conservative management group. Conclusion: Patients with OPTX due to chest trauma (blunt or penetrating), without requiring assisted ventilation and hemodynamically stable, can be safely conservative managed with close monitoring for 24 hours, with a lower rate of complications and hospital stay.
RESUMO
Background: Axillary lymph node status is one of the most important prognostic factors for breast cancer. Sentinel lymph node biopsy (SLNB) after mastectomy is highly controversial. There is not enough data about SLNB in the early period after nipple?sparing mastectomy (NSM). This study investigated the feasibility of SLNB in the early postoperative period of NSM. Materials and Methods: Patients who were operated on for breast cancer in Acibadem Maslak Hospital between 2009 and 2018 were searched retrospectively. Results of SLNB as the second session in patients whose final pathology report revealed breast carcinoma after contralateral/bilateral prophylactic mastectomy and mastectomy for benign lesions were evaluated. Results: In the early period (median 14 days) after NSM, SLNB was performed by intradermal radioisotope injection in five patients with occult breast cancer in contralateral/bilateral prophylactic mastectomy and in one patient with preoperatively suspicious mass which yielded breast cancer at final pathology. In five (80%) patients, SLNB was performed, whereas in one patient axillary lymph node dissection (ALND) was performed due to the undetectability of SLN. In one patient, micrometastasis was observed, whereas no metastasis was observed in other patients including the one who underwent ALND. No complication due to SLNB was detected. No recurrence and distant metastasis were detected in a mean follow?up of 42.82 (19�) months. While SLNB did not change the treatment of patients with contralateral occult carcinoma, other patients had hormonal therapy due to negative SLNB. Conclusion: SLNB in the early postoperative period of NSM can be performed by intradermal radioisotope injection. However, further studies are needed to determine the feasibility of SLNB in the early postoperative period of NSM
RESUMO
Introdução: A Radiolucência intracoronal pré eruptiva (PECR) é um achado radiográfico, com aspecto de lesão radiolúcida na dentina coronária, adjacente a junção amelodentinária, em dentes não irrompidos. Objetivo: Relatar um caso de possível reabsorção intracoronal pré-eruptiva com destruição extensa de dentina e envolvimento pulpar de um segundo molar permanente recém-erupcionado. Método: Após definição do diagnóstico, optou-se por um tratamento conservador, com a realização de capeamento pulpar direto com a finalidade de manutenção da vitalidade pulpar e término de formação das raízes. Resultado: Após o tratamento, paciente permaneceu assintomática no controle de quinze dias, com teste de vitalidade normal e sem sinais de inflamação. Conclusão: A interpretação cuidadosa do exame radiográfico é crucial para a detecção precoce e manejo adequado dessas lesões.
Pre-eruptive intracoronal radiolucency (PECR) is a radiographic finding, with the appearance of a radiolucent lesion in the coronary dentin, adjacent to the dentinal-enamel junction, in unerupted teeth. Objective: To report a case of possible pre-eruptive intracoronal resorption with extensive dentin destruction and pulpal involvement of a newly erupted second permanent molar. Method: After defining the diagnosis, a conservative treatment was chosen, with direct pulp capping in order to maintain pulp vitality and end root formation. Result: After treatment, the patient remained asymptomatic in the fifteen-day control, with normal vitality test and no signs of inflammation. Conclusion: Careful interpretation of the radiographic examination is crucial for early detection and proper management of these lesions.
RESUMO
Objective:To observe and analyze the superficial retinal blood flow density and its related influencing factors in the macular area of adolescents with different types of non-pathological high myopia (HM).Methods:A retrospective clinical study. From March to August 2022, 117 eyes of 117 adolescents who were admitted to Liaocheng Aier Eye Hospital due to myopia were included in the study. According to equivalent spherical degree (SE) and corneal curvature, subjects were divided into mild myopia or emmetropia group (control group), HM group, occult HM (OHM) group, and super HM (SHM) group, with 30 eyes, 28 eyes, 35 eyes, and 24 eyes, respectively. All subjects underwent medical optometry, intraocular pressure, optical coherence tomography (OCT), OCT angiography (OCTA), axial length (AL) and corneal curvature measurements. The diopter was SE. OCTA instrument was used to scan the macular region in the range of 6 mm×6 mm, and the software automatically divided it into three concentric circles centered on the fovea of the macular, namely, the central area with a diameter of 1 mm, the inner ring area with a diameter of 1-3 mm, and the outer ring area with a diameter of 3-6 mm. The superficial retinal vascular density (SRVD), vascular perfusion density (SBPD), the area, perimeter (PERIM), avascular index (AI) of foveal avascular area (FAZ) and retinal thickness were measured in the macular region as a whole and in different regions. One-way analysis of variance was used to compare the data among groups, and the least significant difference t-test was used to compare the data among groups. The correlation of AL, corneal curvature and intraocular pressure with SRVD and SBPD in macula was analyzed by Pearson correlation analysis. Results:There were significant differences in SRVD and SBPD in the central, inner and outer regions of macula in control group, HM group, OHM group and SHM group ( P<0.05). There were statistically significant differences in the thickness of the retina above, below and on the temporal side of the central and outer ring regions ( P<0.05). However, no statistically significant difference was in the thickness of the retina on the nasal side ( P>0.05). There was no significant difference in PERIM ( P>0.05). There were significant differences in FAZ area and AI ( P<0.05). Correlation analysis showed that AL was negatively correlated with SRVD and SBPD in macular whole and central, inner and outer ring regions ( P <0.05). Corneal curvature and SE were positively correlated with the SRVD and SBPD of macular whole, central area and outer ring area ( P<0.05). AL was negatively correlated with retinal thickness in the outer ring region ( P<0.05). SE was positively correlated with the thickness of the retina above, below and temporally in the outer ring region ( P<0.05). AL was negatively correlated with FAZ area and AI ( P<0.05). SE was positively correlated with FAZ area and PERIM ( P<0.05). Retinal thickness was positively correlated with SRVD and SBPD ( P<0.05). Conclusions:The SRVD and SBPD of different types of HM in adolescents decreases to different degrees. The thickness of the retina in the central region is thicker, and the retina in the outer ring region is thinner. With the decrease of SRVD, the retinal thickness gradually is thinner.
RESUMO
@#Tonsillar malignancy typically presents with asymmetrical tonsillar enlargement, lesion on the tonsils, sore throat or a neck mass. We report a case of unsuspected tonsillar malignancy in a 56-year-old gentleman who presented with symptoms of obstructive sleep apnoea. His tonsils were grade III bilaterally with normal mucosa. Tonsillectomy was performed to improve patient’s compliance with Continuous Positive Airway Pressure (CPAP) therapy. These tonsillar specimens were reported to be Mantle Cell Lymphoma (MCL) based on the histology and ancillary studies. This case highlights that benign-looking symmetrical tonsillar enlargement can harbour occult malignancy. It is important to note that OSA symptoms may be the presentation for haematological malignancies. Tonsillar specimens should be sent for histopathological examination regardless of the indication to avoid misdiagnosis and delay in treatment.
RESUMO
@#This paper documents the utility of ultrasound-guided tru-cut biopsy in the diagnosis and subsequent management of a case of occult breast carcinoma presenting with multiple distant metastases in the absence of a primary breast lesion. She was initially diagnosed as primary ovarian malignancy with metastatic disease and subsequently underwent transvaginal ultrasound-guided tru-cut biopsy of the right ovarian mass. Histologic and immunohistochemical studies were consistent with a metastatic adenocarcinoma of breast origin. The patient underwent chemotherapy for primary breast carcinoma and has responded well.

【Objective】 To evaluate the role of anti-HBc detection in current blood screening strategy by the follow-up of repeated donors with antibody to hepatitis B virus core antigen. 【Methods】 Plasma samples were collected randomly from Dalian Blood Center. to test anti-HBc(dual reagents) and anti-HBs via ELISA. The re-donation of eligible donors who were anti-HBc+ and donors reactive to HBV detection were followed up. 【Results】 A total of 1 291 plasma samples were collected randomly from May 2017 to March 2018, among which 405 samples(31.4%)were anti-HBc+. The median age of anti-HBc+ group was observed much higher than that of anti-HBc-group (39 vs 31 years old) (P0.05). Among the 405 anti-HBc+ donors, 3 donors were OBI (0.7%), of which one was screened out in second donation. No HBV DNA was detected out in 3 OBI cases. 【Conclusion】 Although anti-HBc detection is not suitable in blood screening currently, it is of great value in the assessment of blood donor re-entry for HBV reactive donors in blood screening due to the high anti-HBc prevalence among blood donors.
RESUMO
Huangtu Decoction, first recorded in Essentials from the Golden Cabinet(Jin Kui Yao Lue) from ZHANG Zhong-jing in Han dynasty, is used to treat distal bleeding. It is mainly treated for the syndrome of failing to control blood with spleen-yang deficiency. The connotation of distal bleeding is more extensive, including not only upper gastrointestinal bleeding in the traditional sense such as peptic ulcer bleeding, gastrointestinal tumors, gastric mucosal lesions, vascular dysplasia, esophagogastric variceal bleeding, and pancreatic and biliary tract injury, but also other anorectal diseases such as part colon and rectal cancer swelling or polyps, hemorrhoids, and anal fissure and other parts of bleeding such as epistaxis, thrombocytopenia, functional uterine bleeding, threatened abortion, and unexplained hematuria. Distal bleeding also involves syndromes of failing to keep part deficient and cold fluids in interior, such as nocturia, enuresis, clear nose, sweating, cold tears, and leucorrhea, and excessive gastrointestinal bleeding caused by anti-plate and anticoagulant drugs, unexplained positive in the fecal occult blood test, and other modern clinical new problems. The indications of Huangtu Decoction include not only lower blood, defecation before blood, distant blood, hematemesis, epistaxis, and other diseases in traditional Chinese medicine, but also three types of clinical manifestations including bleeding, deficiency syndrome, and stagnant heat syndrome. In the clinic, Huangtu Decoction can be used to treat acute upper gastrointestinal bleeding, acute coronary syndrome complicated with acute upper gastrointestinal bleeding, bleeding events caused by excessive antiplatelet and anticoagulant drugs, unexplained positive in the fecal occult blood test, gastrointestinal tumor with bleeding, thrombocytopenia, and other acute and critical diseases. The dosage of Cooking Stove Earthkey, Rehmanniae Radix, and Asini Corii Colla in Huangtu Decoction is the key to hemostasis.

Objective: To evaluate the participation rate and detection of colorectal neoplasms based on annual fecal immunochemical testing (FIT) for three consecutive years in a population-based colorectal cancer screening program in China. Methods: Based on a population-based colorectal cancer screening program conducted from May 2018 to May 2021 in 6 centers in China, 7 793 eligible participants aged 50-74 were included and offered free FIT and colonoscopy (for those who were FIT-positive on initial screening). At baseline, all participants were invited to receive FIT. In subsequent screening rounds, only FIT-positive participants who did not undergo colonoscopy or FIT-negative participants were invited to have repeated FIT screening. FIT-positive participants were recommended to undertake colonoscopy and pathological examination (if abnormalities were found during colonoscopy). An overall of three rounds of annual FIT screening were conducted. The primary outcomes of the study were the participation rate of FIT screening, the compliance rate of colonoscopy for FIT-positive participants, and the detection rate of colorectal neoplasms. Results: Among the 7 793 participants included in this study, 3 310 (42.5%) were male, with age of (60.50±6.49) years. The overall participation rates for the first, second and third round of FIT screening were 94.0%(7 327/7 793), 86.8% (6 048/6 968) and 91.3% (6 113/6 693), respectively. Overall, 7 742 out of 7 793 participants (99.3%) attended at least one round of screening, and 5 163 out of 7 793 participants (66.3%) attended all three rounds of screening. The positivity rate was significantly higher in the first (14.6%, 1 071/7 327) round compared with the second (5.6%, 3 41/6 048) and third (5.5%, 3 39/6 113) screening rounds (P<0.001). The overall compliance rates of colonoscopy examination among FIT-positive subjects were over 70% in three rounds, which were 76.3% (817/1 071), 75.7% (258/341) and 71.7% (243/339), respectively. In a multivariate logistic regression model considering factors including sex, education background, smoking, alcohol drinking, previous colonoscopy examination, colonic polyp history and family history of colorectal cancer among first-degree relatives, gender and smoking status were related factors affecting the participation rate of FIT screening, with higher rate in males and non-smokers. In addition, logistic regression analysis also found that age was negatively correlated with the compliance rate of colonoscopy in FIT positive patients. The detection rate of advanced tumors (colorectal cancer + advanced adenoma) declined from the first round to subsequent rounds [1st round: 1.15% (90/7 793); 2nd round: 0.57% (40/6 968); and 3rd round: 0.58% (39/6 693)], however, the positive predictive value for advanced neoplasms increased round by round, and was 11.02% in the first screening round, 15.50% in the second screening round, and 16.05 % in the third screening round. In each screening round, the detection rate for advanced neoplasms was higher in men than that in women, and increased with age. Conclusions: Annual repeated FIT screening has high acceptance and satisfying detection rates in the Chinese population. To optimize and improve the effectiveness of colorectal cancer screening, multi-round repeated FIT screening should be implemented while ensuring high participation rates.

The positivity rate was significantly higher in the first (14.6%, 1 071/7 327) round compared with the second (5.6%, 3 41/6 048) and third (5.5%, 3 39/6 113) screening rounds (P<0.001). The overall compliance rates of colonoscopy examination among FIT-positive subjects were over 70% in three rounds, which were 76.3% (817/1 071), 75.7% (258/341) and 71.7% (243/339), respectively. In a multivariate logistic regression model considering factors including sex, education background, smoking, alcohol drinking, previous colonoscopy examination, colonic polyp history and family history of colorectal cancer among first-degree relatives, gender and smoking status were related factors affecting the participation rate of FIT screening, with higher rate in males and non-smokers. In addition, logistic regression analysis also found that age was negatively correlated with the compliance rate of colonoscopy in FIT positive patients. The detection rate of advanced tumors (colorectal cancer + advanced adenoma) declined from the first round to subsequent rounds [1st round: 1.15% (90/7 793); 2nd round: 0.57% (40/6 968); and 3rd round: 0.58% (39/6 693)], however, the positive predictive value for advanced neoplasms increased round by round, and was 11.02% in the first screening round, 15.50% in the second screening round, and 16.05 % in the third screening round. In each screening round, the detection rate for advanced neoplasms was higher in men than that in women, and increased with age. Conclusions: Annual repeated FIT screening has high acceptance and satisfying detection rates in the Chinese population. To optimize and improve the effectiveness of colorectal cancer screening, multi-round repeated FIT screening should be implemented while ensuring high participation rates.

@#Post-COVID-19 conditions encompass a wide range of health problems, including enteritis, but their association with parasitic infections has not yet been investigated. This study analyzed gastrointestinal symptoms, medical histories, fecal Cryptosporidium oocysts, and the history of COVID-19 infection in patients who attended the Faculty of Medicine, Cairo University, from January to July 2021. Fecal biomarkers, including H. pylori, occult blood, fecal calprotectin (FCAL), and TNF-a, were measured, and Cryptosporidium spp. genotypes were molecularly characterized among post-COVID-19 patients using RFLP. Preliminary results from 210 post-COVID-19 patients revealed that group 1 (Cryptosporidiumpositive) (n = 49) and group 2 (Cryptosporidium-negative) (n = 161) showed no significant difference in the prevalence rate of diabetes mellitus (DM). While group 2 was linked to diarrhea, only infections with Cryptosporidium post-COVID-19 were related to chronic diarrhea, vomiting, and weight loss. A total of 220 healthy subjects served as negative controls. Administering azithromycin, hydroxychloroquine, and ivermectin was significantly related to an increased risk of Cryptosporidium infection in group 1, whereas only azithromycin was more frequently recorded in group 2. Antioxidant supplementation insignificantly affected the incidence of cryptosporidiosis. Cryptosporidiosis with a history of COVID-19 was linked to H. pylori infections, increased inflammatory biomarkers (FCAL and TNF-a), and occult blood when compared with group 2. Cryptosporidium genotype 1 was the most commonly occurring subset in individuals with post-COVID-19. The findings demonstrated that aggravating gastrointestinal manifestations, increased fecal biomarkers and anti-COVID-19 therapeutic interventions are significantly related to the existence of Cryptosporidium oocysts in patients with post-COVID-19, indicating the predominance of.
RESUMO
Aims: the current research aimed to investigate LncRNA-MIAT in patients with nonHodgkin lymphoma (NHL) and to assess its correlation with clinicopathological features and treatment protocols of NHLs among Egyptian patients with Occult hepatitis C virus (HCV) infection (OCI). Patients & Methods: This study was conducted on 20 patients with NHL and 30 healthy subjects as the control group. All subjects were screened for HCV-RNA in both plasma and PBMCs. RT-PCR determined lncRNA-MIAT. Results: lncRNA-MIAT relative expression level was upregulated in NHL groups (2.73±0.86) compared to controls (1.06±0.07), P Ë0.001*. Among NHL, patients with OCI (3.2±0.63) had significantly higher levels of lncRNA-MIAT compared to HCV (2.6±1.08) and non-HCV (2.4±0.4), P Ë0.001*. Additionally, the relative expression levels of lncRNA-MIAT were significantly positively correlated with laboratory and clinicopathological features of NHL. Interestingly, concerning the treatment of DLBCLNHL, there were significantly higher levels of lncRNA-MIAT in no treatment subgroup (n=10, 3.31±0.95) compared to successfully treated subgroups [CHOP (n=7, 1.58±0.34) and R-CHOP (n=3, 11.16±0.21), P Ë0.001* Conclusions: lncRNA-MIAT level was upregulated in NHL patients, particularly patients with OCI. Thus, circulatory lncRNA-MIAT may serve as a promising non-invasive diagnostic marker for NHL associated with OCI

ABSTRACT BACKGROUND: Occult hepatitis B virus infection (OBI) is defined as the presence of hepatitis B virus (HBV) deoxyribonucleic acid (DNA) in the liver of individuals with undetectable hepatitis B virus surface antigen (HBsAg) in the serum. The actual prevalence of OBI and its clinical relevance are not yet fully understood. OBJECTIVE: To evaluate the prevalence of HBV DNA in liver biopsies of HBsAg-negative patients with chronic liver disease of different etiologies in a referral center in Brazil and compare two different HBV DNA amplification protocols to detect HBV. DESIGN AND SETTING: This cross-sectional observational study was conducted at the Liver Outpatient Clinic, Hospital das Clínicas, Universidade Federal de Minas Gerais, Belo Horizonte, MG, Brazil, between January 2016 and December 2019. METHODS: HBV DNA was investigated in 104 liver biopsy samples from individuals with chronic liver disease of different etiologies, in whom HBsAg was undetectable in serum by nested-polymerase chain reaction (nested-PCR), using two different protocols. RESULTS: OBI, diagnosed by detecting HBV DNA using both protocols, was detected in 6.7% of the 104 individuals investigated. Both protocols showed a good reliability. CONCLUSION: In addition to the differences in the prevalence of HBV infection in different regions, variations in the polymerase chain reaction technique used for HBV DNA amplification may be responsible for the large variations in the prevalence of OBI identified in different studies. There is a need for better standardization of the diagnostic methods used to diagnose this entity.
