Management of medical actions carried out in handling patients who are ODP (people under monitoring), OTG (asymptomatic people), PDP (patient under monitoring) and positive Covid-19 patients is carried out based on assumptions, such as self-isolation, hospitalization, or special treatments in the ICU (Intensive Care Unit) room. The condition of the body in each patient is different, a patient may have same symptoms but the treatment is different, especially in elderly patients. Many problems occur in determining medical action because the patient's body condition is different. Therefore, it needs to be appointed as a research. The research method used in this study was Nive Bayes algorithm with supporting application Rapid Miner. It was applied to carry out the process of testing on patient data as much as 500 data, 25 variables or patient symptoms and 3 outputs as a form of medical action. Based on the results of the analysis carried out in this study, prediction of medical actions for ODP, PDP, OTG and positive Covid-19 patients were obtained by comparing training data with testing data using Rapid Miner application. It resulted that an accuracy rate of 76.00% was obtained

Goprint is an Online Printing Marketplace that connects printing services with users who want to print documents quickly without the need to queue. In the span of time from April 2019 to September 2019 it was found that the number of Goprint users reached 407 users, 24 partners, and 256 orders. From transactions that have been carried out by users, not a few orders are often canceled due to ineffective Goprint features or poor partner performance. This causes Goprint users to feel dissatisfied with the services provided by the Goprint application. The Naive Bayes algorithm is one of the algorithms used for classification or grouping of data, but can also be used for decision making. With this algorithm and the problems that occur, the authors make a system to predict the loyalty of Goprint users to anticipate users who stop leaving Goprint because they are not satisfied or loyal users. The data used as training data is 20 and testing data is 10. From the test results it is found that the value of precision is 80%, 100% recall, and 90% accuracy.

SARS-CoV-2 nasopharyngeal shedding contributes to the spread of the COVID-19 epidemic. Among 3271 COVID-19 patients treated at the Hospital University Institute Méditerranée Infection, Marseille, France from 3 March to 27 April 2020, tested at least twice by qRT-PCR, the median SARS-CoV-2 nasopharyngeal shedding duration was 6 days (range 2–54 days). Compared with short shedders (qRT-PCR positivity < 10 days), 34 (1.04%) persistent shedders (qRT-PCR positivity ≥ 17 days; mean ± SD: 23.3 ± 3.8 days) were significantly older, with associated comorbidities, exhibiting lymphopenia, eosinopenia, increased D-dimer and increased troponin (p < 0.05), and were hospitalized in intensive care unit in 17.7% vs. 1.1% of cases (p < 0.0001). Viral culture was positive in six persistent shedders after day 10, including in one patient after day 17, and no viral co-pathogen was detected in 33 tested patients. Persistent shedders received azithromycin plus hydroxychloroquine ≥ 3 days in 26/34 (76.5%) patients, a figure significantly lower than in short shedders (86.6%) (p = 0.042). Accordingly, mortality was 14.7% vs. 0.5% (p < 0.0001). Persistent shedding was significantly associated with persistent dyspnea and anosmia/ageusia (p < 0.05). In the context of COVID-19 treatment, including treatment with azithromycin plus hydroxychloroquine, the persistence of SARS-CoV-2 nasopharyngeal shedding was a rare event, most frequently encountered in elderly patients with comorbidities and lacking azithromycin plus hydroxychloroquine treatment.

Abstract Background Postoperative delirium (POD) is a relevant and underdiagnosed complication after cardiac surgery that is associated with increased intensive care unit (ICU) and hospital length of stay (LOS). The aim of this subgroup study was to compare the frequency of tested POD versus the coded International Statistical Classification of Diseases and Related Health Problems (ICD) diagnosis of POD and to evaluate the influence of POD on LOS in ICU and hospital. Methods 254 elective cardiac surgery patients (mean age, 70.5 ± 6.4 years) at the University Hospital Bonn between September 2018 and October 2019 were evaluated. The endpoint tested POD was considered positive, if one of the tests Confusion Assessment Method for ICU (CAM-ICU) or Confusion Assessment Method (CAM), 4 'A's Test (4AT) or Delirium Observation Scale (DOS) was positive on one day. Results POD occurred in 127 patients (50.0%). LOS in ICU and hospital were significantly different based on presence (ICU 165.0 ± 362.7 h; Hospital 26.5 ± 26.1 days) or absence (ICU 64.5 ± 79.4 h; Hospital 14.6 ± 6.7 days) of POD (p < 0.001). The multiple linear regression showed POD as an independent predictor for a prolonged LOS in ICU (48%; 95%CI 31–67%) and in hospital (64%; 95%CI 27–110%) (p < 0.001). The frequency of POD in the study participants that was coded with the ICD F05.0 and F05.8 by hospital staff was considerably lower than tests revealed by the study personnel. Conclusion Approximately 50% of elderly patients who underwent cardiac surgery developed POD, which is associated with an increased ICU and hospital LOS. Furthermore, POD is highly underdiagnosed in clinical routine.

Objectives: Elderly patients requiring emergency general surgery (EGS) are at high risk for complications due to preexisting malnutrition. Thus, correcting nutritional deficits perioperatively is essential to improve outcomes. However, even in patients unable to tolerate enteral nutrition, initiation of parenteral nutrition (PN) is often delayed due to concerns of associated complications. In this study, we hypothesized that in elderly EGS patients with relative short-term contraindications to enteral nutrition, early administration of PN is as safe as delayed administration. Furthermore, early PN may improve outcomes by enhancing caloric intake and combatting malnutrition in the immediate perioperative period. Design and Setting: A single-institution, retrospective review was performed at a quaternary academic medical center. Participants: Participants consisted of 58 elderly patients >65 years of age admitted to the EGS service who required PN between July 2017 and July 2020. Measurements: Postoperative outcomes of patients started on PN on hospital day 0-3 (early initiation) were compared to patients started on PN on hospital day 4 or later (late initiation). Bivariate analysis was conducted using the Chi-square or Fisher’s exact test for categorical variables and the Wilcoxon-Mann-Whitney test and F-test for continuous variables. Results: Fifty-eight patients met inclusion criteria, with 27 (46.6%) patients receiving early PN and 31 (53.4%) receiving late PN. Both groups shared similar baseline characteristics, including degree of frailty, body mass index, and nutritional status at time of admission. Complications associated with PN administration were negligible, with no instances of central venous catheter insertion-related complications, catheter-associated bloodstream infection, or factors leading to early termination of PN therapy. A significantly higher proportion of patients in the early administration group met 60% of their caloric goal within 72 hours of admission (62.9% versus 19.5%, p=0.0007). Patients receiving late PN demonstrated a significantly higher rate of unplanned admission to the intensive care unit (38.7% versus 14.8%, p=0.04). Moreover, there was a 21.5% reduction in mortality among patients in the early initiation group compared to patients in the late initiation group (33.3% versus 54.8%, p=0.10). Conclusions: Early initiation of PN in hospitalized elderly EGS patients was not associated with increased adverse events compared to patients undergoing delayed PN administration. Furthermore, patients receiving early PN demonstrated a 2.6-fold decrease in the rate of unplanned admission to the intensive care unit and trended toward improved mortality. Based on these results, further prospective studies are warranted to further explore the safety and potential benefits of early PN administration in elderly surgical patients unable to receive enteral nutrition.

Organophosphate compounds are used as commercial insecticides and applied as aerosols or dust. Consuming these compounds intentionally or unintentionally lead to dangerous conditions even to fatality. The most common obstacle in treating organophosphorus poisoning is the availability of sufficient medical care, equipment to provide proper emergency care observed in rural areas where there is a lot of gap between intensive care and acute care. Atropine use is as an antidote in organophosphorus poisoning. The dose of atropine mainly depends on the organophosphorus toxic doses. Atropine is a competitive antagonist of acetylcholine at the muscarinic postsynaptic membrane. Atropine blocks all the muscarinic effects in the body. This study presents a case of organophosphorus poisoning treated with atropine leading to atropine psychosis. Patient’s conditions, outcomes, and improvements are studied.
