This work aimed to report values on oral hygiene habits at home during the pandemic and compare the differences between previous oral hygiene habits. A total of 1,136 questionnaires were filled in via a link sent through email to the patients. The answers show that although they had more time during the pandemic, they spent less time on dental and tongue hygiene. Dental and tongue hygiene are key to maintaining systemic health. The questionnaire was sent by e-mail to 1,136 male and female patients throughout Italy. Demonstrate and understand whether patients during the pandemic cleaned and spent time cleaning and maintaining their teeth and tongue hygiene. The questionnaire testifies to the fact that it is not the time but the patient's compliance and motivation that makes the difference.

Objective: This work aimed to report values regarding oral hygiene habits at home during the pandemic and compare the difference with previous oral hygiene habits.

Methods: This study was performed anonymously and had patients answer an online questionnaire. The questionnaire consisted of 11 closed-answer questions (except 1) concerning oral hygiene habits at home at the time of COVID-19 and participant characteristics, including gender and age. A total of 1,136 questionnaires were filled in via a link sent by email to the patients.

Results: Among the 1,136 patients examined, 32.4% (372) were male and 67.6% (775) were female, and almost half (47.9%) of the patients who answered the questionnaire were aged 18-40 years. Patients who participated in our survey were asked questions related to dental and tongue hygiene. The answers showed that although they had more time during the pandemic, they brushed their teeth less and did not brush their tongues regularly.

Conclusion: Patients with periodontal problems usually have less time for brushing and do not have good plaque control. The questionnaire showed the opposite, such that the patient's compliance and motivation matters more than time. Thus, dentists and dental hygienists must encourage and make patients understand the importance of oral hygiene at home.

这项工作旨在报告疫情期间家庭口腔卫生习惯的价值,并比较以前口腔卫生习惯之间的差异。通过电子邮件发送给患者的链接,共填写了1136份问卷。答案表明,尽管他们在疫情期间有更多的时间,但他们在牙齿和舌头卫生上花费的时间更少。牙齿和舌头卫生是保持系统健康的关键。调查问卷通过电子邮件发送给意大利全国1136名男性和女性患者。展示并了解患者在疫情期间是否清洁并花时间清洁和保持牙齿和舌头卫生。调查问卷证明,造成差异的不是时间,而是患者的依从性和动机。目的:本工作旨在报告疫情期间家庭口腔卫生习惯的价值,并将其与以往口腔卫生习惯进行比较。方法:这项研究是匿名进行的,让患者回答在线问卷。该问卷由11个封闭式回答问题(除1个问题外)组成,涉及新冠肺炎发生时家中的口腔卫生习惯和参与者特征,包括性别和年龄。通过电子邮件发送给患者的链接,共填写了1136份问卷。结果:在1136名接受调查的患者中,32.4%(372)为男性,67.6%(775)为女性,回答问卷的患者中几乎有一半(47.9%)年龄在18-40岁之间。参与我们调查的患者被问及与牙齿和舌头卫生有关的问题。答案表明,尽管他们在疫情期间有更多的时间,但他们刷牙较少,也没有定期刷牙。结论:有牙周问题的患者通常刷牙时间较少,牙菌斑控制不好。问卷显示情况恰恰相反,患者的依从性和动机比时间更重要。因此,牙医和牙科保健师必须鼓励并让患者了解家庭口腔卫生的重要性。

Objective: The primary aim of this study was to understand the difference in the use of Telemedicine by Brazilian physicians before and after the onset of COVID-19 pandemic and their intention to continue using it post the pandemic period. The secondary objective was to analyze the differences of opinion between physicians in the private and public sectors.

Methods: We conducted an online medical survey through the SurveyMonkey platform in a large hospital in São Paulo, Brazil, from May to July 2022.

Results: Three-hundred-and -two physicians responded to the survey. We found that there was a significant increase in the number of physicians who started using Telemedicine in both the public and private sectors (p<0.0001) since the onset of COVID-19 pandemic and that >50% of them intend to continue using Telemedicine in their daily practice. Most responders consider that Telemedicine is useful in screening, diagnosis and management of patients; that it facilitates the physician's daily practice; that it can maintain or even add financial gains through reducing office expenses; and that is another medium for dispensing medical care. They also believe that Telemedicine should be regulated by the Brazilian Federal Council of Medicine. There were no significant differences between the responses from private and public sector physicians.

Conclusion: Telemedicine has played a major role in healthcare since the onset of COVID-19 pandemic and most of the physicians approve its use and intend to continue using Telemedicine in their daily practice.

目的:本研究的主要目的是了解巴西医生在新冠肺炎大流行前后使用远程医疗的差异,以及他们在大流行后继续使用远程医疗。第二个目的是分析私营和公共部门医生之间的意见分歧。方法:2022年5月至7月,我们通过SurveyMonkey平台在巴西圣保罗的一家大型医院进行了一项在线医学调查。结果:322名医生对调查做出了回应。我们发现,在公共和私营部门,开始使用远程医疗的医生数量显著增加(p50%的受访者打算在日常实践中继续使用远程医疗。大多数受访者认为远程医疗在筛查、诊断和管理患者方面很有用;它有助于医生的日常实践;它可以通过减少办公室开支来维持甚至增加经济收益;这是另一种提供医疗服务的媒介emedicine应由巴西联邦医学委员会监管。私营部门和公共部门医生的回答没有显著差异。结论:自新冠肺炎大流行开始以来,远程医疗在医疗保健中发挥了重要作用,大多数医生批准使用远程医疗,并打算在日常实践中继续使用远程医疗。

Objective: The incidence of thrombotic events and acute kidney injury is high in critically ill patients with COVID-19. We aimed to evaluate and compare the coagulation profiles of patients with COVID-19 developing acute kidney injury versus those who did not, during their intensive care unit stay.

Methods: Conventional coagulation and platelet function tests, fibrinolysis, endogenous inhibitors of coagulation tests, and rotational thromboelastometry were conducted on days 0, 1, 3, 7, and 14 following intensive care unit admission.

Results: Out of 30 patients included, 13 (43.4%) met the criteria for acute kidney injury. Comparing both groups, patients with acute kidney injury were older: 73 (60-84) versus 54 (47-64) years, p=0.027, and had a lower baseline glomerular filtration rate: 70 (51-81) versus 93 (83-106) mL/min/1.73m2, p=0.004. On day 1, D-dimer and fibrinogen levels were elevated but similar between groups: 1780 (1319-5517) versus 1794 (726-2324) ng/mL, p=0.145 and 608 (550-700) versus 642 (469-722) g/dL, p=0.95, respectively. Rotational thromboelastometry data were also similar between groups. However, antithrombin activity and protein C levels were lower in patients who developed acute kidney injury: 82 (75-92) versus 98 (90-116), p=0.028 and 70 (52-82) versus 88 (78-101) µ/mL, p=0.038, respectively. Mean protein C levels were lower in the group with acute kidney injury across multiple time points during their stay in the intensive care unit.

Conclusion: Critically ill patients experiencing acute kidney injury exhibited lower endogenous anticoagulant levels. Further studies are needed to understand the role of natural anticoagulants in the pathophysiology of acute kidney injury within this population.

目的:新冠肺炎危重患者血栓性事件和急性肾损伤的发生率较高。我们旨在评估和比较新冠肺炎急性肾损伤患者与未发生急性肾损伤的患者在重症监护室期间的凝血情况。方法:在重症监护室入院后第0、1、3、7和14天进行常规凝血和血小板功能测试、纤维蛋白溶解、内源性凝血抑制剂测试和旋转血栓弹性测定。结果:在纳入的30名患者中,13名(43.4%)符合急性肾损伤的标准。比较两组,急性肾损伤患者年龄较大:73岁(60-84岁)对54岁(47-64岁),p=0.027,基线肾小球滤过率较低:70(51-81)对93(83-106)mL/min/1.73m2,p=0.004。第1天,D-二聚体和纤维蛋白原水平升高,但各组之间相似:1780(1319-5517)对1794(726-2324)ng/mL,p=0.145;608(550-700)对642(469-722)g/dL,p=0.95。两组之间的旋转血栓弹性测量数据也相似。然而,急性肾损伤患者的抗凝血酶活性和蛋白C水平较低:分别为82(75-92)对98(90-116),p=0.028和70(52-82)对88(78-101)µ/mL,p=0.038。在重症监护室的多个时间点上,急性肾损伤组的平均蛋白质C水平较低。结论:急性肾损伤的危重患者表现出较低的内源性抗凝剂水平。需要进一步的研究来了解天然抗凝剂在该人群急性肾损伤病理生理学中的作用。

Scurvy and food selectivity in childhood: a case report. 儿童坏血病与食物选择性:一例报告。

Despite its rarity, symptomatic micronutrient deficiency remains a public health problem. Scurvy is the differential diagnosis for bleeding disorders and hematological and rheumatological diseases, especially in patients with eating disorders. However, it is unrelated to autism spectrum disorders or other neurodevelopmental disorders. A previously healthy 10-year-old boy living in São Paulo, Brazil, had a history of significant food selectivity unrelated to autism spectrum disorder, resulting in symptomatic ascorbic acid deficiency (scurvy). This resulted in pain and purpuric lesions on the lower limbs, gingival edema, bleeding during tooth brushing, asthenia, weakness, malaise, and sadness. Therefore, dietary anamnesis is important for routine monitoring of child growth and development. This process helps prevent nutritional deficiencies, facilitates early diagnosis of eating disorders, and enables multidisciplinary follow-up for these patients.

尽管症状性微量营养素缺乏症很罕见,但它仍然是一个公共卫生问题。坏血病是出血性疾病、血液学和风湿病的鉴别诊断,尤其是饮食失调患者。然而,它与自闭症谱系障碍或其他神经发育障碍无关。一名居住在巴西圣保罗的10岁健康男孩有明显的食物选择性病史,与自闭症谱系障碍无关,导致症状性抗坏血酸缺乏症(坏血病)。这导致下肢疼痛和purpuric病变、牙龈水肿、刷牙时出血、乏力、虚弱、不适和悲伤。因此,饮食记忆对于儿童生长发育的常规监测非常重要。这一过程有助于预防营养缺乏,促进饮食失调的早期诊断,并使这些患者能够进行多学科随访。

Objective: The variation in mortality rates of intensive care unit oncological patients may imply that clinical characteristics and prognoses are very different between specific subsets of patients with cancer. The specific characteristics of patients with cancer have not been included as risk factors in the established severity-of-illness scoring systems and comorbidity scores, showing limitations in predicting mortality risk. This study aimed to devise a predictive tool for in-hospital mortality for adult patients with a respiratory neoplasm admitted to the intensive care unit, using an artificial neural network.

Methods: A total of 1,221 stays in the intensive care unit from the Beth Israel Deaconess Medical Center were studied. The primary endpoint was the all-cause in-hospital mortality prediction. An artificial neural network was developed and compared with six severity-of-illness scores and one comorbidity score. Model building was based on important predictors of lung cancer mortality, such as several laboratory parameters, demographic parameters, organ-supporting treatments, and other clinical information. Discrimination and calibration were assessed.

Results: The AUROC for the multilayer perceptron was 0.885, while it was <0.74 for the conventional systems. The AUPRC for the multilayer perceptron was 0.731, whereas it was ≤0.482 for the conventional systems. The superiority of multilayer perceptron was statistically significant for all pairwise AUROC and AUPRC comparisons. The Brier Score was better for the multilayer perceptron (0.109) than for OASIS (0.148), SAPS III (0.163), and SAPS II (0.154).

Conclusion: Discrimination was excellent for multilayer perceptron, which may be a valuable tool for assessing critically ill patients with lung cancer.

目的:重症监护病房肿瘤患者死亡率的变化可能意味着癌症患者的临床特征和预后在特定亚群之间有很大差异。癌症患者的具体特征尚未被纳入已建立的疾病严重程度评分系统和合并症评分中的风险因素,这表明预测死亡风险的局限性。这项研究旨在使用人工神经网络设计一种预测重症监护室呼吸系统肿瘤成年患者住院死亡率的工具。方法:对贝斯以色列女执事医疗中心的1221名重症监护病房住院患者进行研究。主要终点是全因住院死亡率预测。开发了一种人工神经网络,并将其与六种疾病严重程度评分和一种共病评分进行了比较。模型建立基于癌症死亡率的重要预测因素,如几个实验室参数、人口统计学参数、支持器官的治疗和其他临床信息。对辨别和校准进行了评估。结果:多层感知器的AUROC为0.885,而结论:多层感知器具有良好的辨别能力,这可能是评估癌症危重患者的有价值的工具。

Roux-en-Y gastric bypass, a procedure proven effective for treating morbid obesity and metabolic disorders, carries the risk of complications such as the formation of internal hernias. These hernias are often difficult to diagnose and can be potentially fatal because they can cause structural obstruction. Most internal hernias occur in the jejunojejunostomy mesentery space, followed by Petersen's space hernias, although herniation at other locations can also occur. Our case report presents an example of a rare internal hernia after laparoscopic Roux-en-Y gastric bypass. A 36-year-old woman presented with an uncommon internal hernia located between the liver and alimentary loop, resulting in the formation of a new space and consequently incarcerating the entire biliopancreatic loop. This type of internal hernia is rare and has not been reported in the literature, indicating that this is the first report of such a case. In this case, we realized that the diagnosis was challenging and imaging examinations could not help determine the etiology of the pain and obstruction. Therefore, videolaparoscopy revealed an uncommon hernia formed by firm adhesion between the hepatic segment III and the alimentary loop mesentery. Our case is an example of an internal hernia that was not detected with a normal computed tomography scan of the abdomen and pelvis. Only diagnostic laparoscopy revealed herniation, effectively preventing further complications for the patient.

Roux-en-Y胃旁路术是一种被证明对治疗病态肥胖和代谢紊乱有效的手术,它有并发症的风险,如形成内疝。这些疝通常很难诊断,并且可能致命,因为它们会导致结构阻塞。大多数内疝发生在空肠-空肠造口术的肠系膜间隙,其次是Petersen间隙疝,尽管其他位置也可能发生疝。我们的病例报告介绍了一例腹腔镜Roux-en-Y胃旁路术后罕见的内疝。一位36岁的女性出现了一种罕见的位于肝脏和消化道之间的内疝,导致形成了一个新的空间,从而使整个胆胰环陷入困境。这种类型的内疝很少见,文献中也没有报道,这表明这是第一例此类病例的报道。在这种情况下,我们意识到诊断具有挑战性,影像学检查无法帮助确定疼痛和阻塞的病因。因此,电视腹腔镜检查发现一种罕见的疝,由肝III段和消化道环肠系膜之间的牢固粘连形成。我们的病例是一个未通过腹部和骨盆的正常计算机断层扫描检测到的内疝的例子。只有诊断性腹腔镜检查才发现疝,有效地预防了患者的进一步并发症。

Objective: To evaluate prenatal and puerperium care levels received and identify their association with sociodemographic and obstetric characteristics.

Methods: This cross-sectional study was conducted from May to December 2020 and included women who gave birth at the Municipal Hospital of Fazenda Rio Grande, Paraná, Brazil. Data were collected through interviews and review of portfolios and medical records. The variables extracted from the prenatal protocols of Paraná and the Ministry of Health were grouped into five compliance indices: CI1 - clinical examination; CI2 - health education; CI3 - queries; CI4 - examinations and vaccines; and CI5 - postpartum appointments. Prenatal care was considered adequate when 80% or more adequacy was obtained.

Results: A total of 307 women participated in this study. Prenatal compliance was 16.6% considering the entire set of variables. The best performance was for CI4 (54.7%) and the worst for CI5 (13.3%). The lowest adequacy occurred among single women (10.9%) compared to those who lived with a partner (19.9%) (p=0.043) and among women with black/brown skin color (9.5%) compared to those with white/yellow skin color (20.3%) (p=0.016).

Conclusion: Most women did not receive adequate care, with those in situations of greater social vulnerability received worse quality care.

目的:评估产前和产褥期护理水平,并确定其与社会人口统计学和产科特征的关系。方法:这项横断面研究于2020年5月至12月进行,包括在巴西巴拉那法曾达里奥格兰德市医院分娩的女性。数据是通过访谈和对档案和医疗记录的审查收集的。从巴拉那和卫生部的产前方案中提取的变量被分为五个依从性指数:CI1-临床检查;CI2——健康教育;CI3-查询;CI4-检查和疫苗;以及CI5——产后预约。当获得80%或以上的充分性时,产前护理被认为是充分的。结果:共有307名女性参与了这项研究。考虑到整个变量,产前依从性为16.6%。表现最好的是CI4(54.7%),最差的是CI5(13.3%)。与伴侣生活的女性(19.9%)(p=0.043)相比,单身女性(10.9%)的适足性最低,与白/黄肤色的女性(20.3%)相比,黑/棕色皮肤的女性(9.5%)的适适足性最差(p=0.016)。结论:大多数女性没有得到足够的护理,而那些社会脆弱性更大的人得到的护理质量更差。

Ferry ships generally have various kinds of cargo such as passengers, motorbikes, livestock, or goods carried by passengers. The process of transferring the load requires a special path or path in its transfer which is called a Ramp door. One of the important factors in making Ramp doors is their strength, so there is a need for strength analysis in rampdoor design on certain types of ships, one of which is multipurpose ships, strength analysis on ramp doors for certain loads can be visualized using solidwork software.In a comparison of the strength analysis between using the software and calculating the stress, the difference is not that significant and the biggest difference is the calculation of the stress on the load of passengers riding motorbikes when going through the Ramp door. From the results obtained in the calculations and the software, there is a difference of 4.29 % with the safety factor in accordance with the rules of safety factor, which exceeds the number 1. 
轮渡船通常有各种各样的货物,如乘客、摩托车、牲畜或乘客携带的货物。在传递荷载的过程中需要一条或多条特殊的路径,这种路径被称为匝道门。斜道门的强度是制作斜道门的重要因素之一,因此在某些类型船舶的斜道门设计中需要进行强度分析,其中一种是多用途船舶,在一定载荷下斜道门的强度分析可以使用solidwork软件进行可视化。在使用软件进行强度分析和计算应力的对比中,差异并不明显,最大的差异是计算了骑摩托车的乘客通过匝道门时的载荷应力。从计算结果和软件计算结果来看,与安全系数规则规定的安全系数相差4.29%,大于1。
