Objective To study the safety and feasibility of implementation of precise radiotherapy with inducement of an apnea-like condition. Methods Two patients with lung tumors underwent precise radiotherapy under an apnea-like condition. The apnea-like condition was induced 11 times between the two patients for tumor localization and treatment. The changes in the blood oxygen saturation, blood pressure, heart rate, and end-tidal carbon dioxide during the apnea-like periods were observed, and the incidence of adverse reactions was recorded. Results The average apnea-like time was 6.2 minutes (range, 3–9 minutes), and the average radiotherapy time was 4.6 minutes (range, 1–7 minutes). The lowest blood oxygen saturation level was 97%, with a change of <1%. The heart rate and average arterial blood pressure increased during the apnea-like periods. Contact sores appeared on the patients’ posterior pharyngeal wall after the first apnea-like period; no other adverse events occurred. Conclusion Precise radiotherapy under an apnea-like condition is safe and feasible for patients with lung tumors.

BACKGROUND: Transnasal esophagogastroduodenoscopy (EGD) without sedation has been reported to be safe and tolerable. It has recently been used widely in Japan for the detection of upper gastrointestinal disease. Alternatively, transoral examination using a thin endoscope has also been reported to be highly tolerable.OBJECTIVE: To examine the cardiocirculatory effects of transoral versus transnasal EGD in an attempt to determine the most suitable endoscopic methods for patients ≥75 years of age.METHODS: Subjects who underwent monitoring of respiratory and circulatory dynamics without sedation during endoscopic screening examinations were enrolled at the New Ooe Hospital (Kyoto, Japan) between April 2008 and March 2009. A total of 165 patients (age ≥75 years) provided written informed consent and were investigated in the present study. Patients were randomly divided into three subgroups: UO group – thin endoscope; SO group – standard endoscope; and UT group – transnasal EGD. Percutaneous arterial blood oxygen saturation, heart rate and blood pressure were evaluated just before EGD and at five time points during EGD. After transnasal EGD, patients who had previously been examined using transoral EGD with a standard endoscope were asked about preferences for their next examination.RESULTS: There were no statistical differences in the characteristics among the groups. Percutaneous oxygen saturation in the UT group showed a transient drop compared with the SO and UO groups at the beginning of the endoscopic procedure. Heart rate showed no significant differences among the SO, UO and UT groups; Systolic blood pressure in the UO group was lower immediately after insertion compared with the SO and UT groups. The rate pressure product in the UO group was comparable with that in the UT group during endoscopy, and the SO group showed a continuously higher level than the UO and UT groups. More than one-half (54.4%) of patients were ‘willing to choose transnasal EGD for next examination’.CONCLUSIONS: For elderly patients, unsedated transnasal EGD failed to show an advantage over unsedated standard endoscopy. Transoral thin EGD was estimated to be safe and tolerable.

Extracorporeal Lithotripsy

Aim. To determine the change of cardiovascular system parameters after extracorporeal lithotripsy.Methods. The study involved 25 patients with urolithiasis from Urology Department of «The first Republican Clinical Hospital of Ministry of Healthcare of Udmurtia» in Izhevsk at the age of 25 to 45 years, of these, 10 females and 15 males. Lithotripsy was performed on all patients. Blood pressure, heart rate, stress index, blood oxygen saturation were measured before and after intervention.Results. The data obtained allow us to conclude that in patients with urolithiasis after extracorporeal lithotripsy no specific changes in baseline cardiovascular system parameters occur. Systolic and diastolic blood pressure ranged between 5 to 10 mm Hg. Heart rate before and after extracorporeal lithotripsy practically did not change, blood oxygen saturation remained unchanged as well. Statistically significant reduction of stress index after extracorporeal lithotripsy was observed.Conclusion. Functional monitoring of patients with urolithiasis after extracorporeal lithotripsy did not reveal any significant changes in blood pressure, heart rate, and blood oxygen saturation; stress index after the intervention statistically significantly decreased, but remains higher than normal.

Underlying Diseases

Introduction: COVID-19 can rapidly cause lung damage and severe respiratory distress and subsequently reduce oxygen saturation (SPO2), especially in generally ill patients, which may be exacerbated if severe clinical symptoms or underlying diseases are added. This may lead to deterioration of blood oxygenation or even increase the risk of death when severe clinical symptoms or underlying diseases are present. Therefore, the aim of this study was to Evaluation of the relationship between arterial blood oxygen saturation level and outcome in COVID-19 patients.Material and Methods: A cross-sectional study of 250 patients referred to Imam Sari Hospital with symptoms of respiratory infection, gastrointestinal, and general symptoms in January 2020 to September 2020. Data were analyzed using SPSS version 26.Results: 27 out of 250 patients died. There is a positive correlation between systemic patient, SPO2 and less than 90% with death results (P<0/02). Patients with heart disease (44.4%), cancer (30.1%), diabetes (11.1%), cerebrovascular accident (18.5%) died (P<0/05). There was no positive correlation between weakness, fever, dyspnea, nausea, and diarrhea and appetite loss with death.Conclusion: Based on the present study, it was found that patients whose clinical symptoms were associated with underlying disease and SPO2 to a severe and critical degree had a higher risk of adverse outcome such as death. People with underlying conditions such as DM, CVD, HTN, and a history of angiography and cancer are also more likely to die due to COVID-19. Most deaths in the present study had low SPO2 at before admission, indicating a strong association between patient mortality and severity of lung involvement and low SPO2.

Abstract One hundred and twenty-six yearling angus steers (initial body weight 445.87 ± 7.13 kg) were utilized in a 2 x 2 factorial design to evaluate the impacts of bunk management and modified distillers grains plus solubles (mDGS) inclusion on feedlot performance, hydrogen sulfide concentrations and blood oxygen saturation. Treatments included bunk management strategy either control bunk management (CON; clean bunks at the time of next day’s feeding) or long bunk management (LONG; feed remaining at time of next day’s feeding), and two inclusion rates of mDGS either 25% or 50% (DM Basis). On d 0, 7, 14, 21, 28 and 35 rumen gas samples were collected via rumenocentesis, and arterial blood samples were collected on two steers from each pen. No differences (P ≥ 0.09) were observed for dry matter intake, average daily gain and gain-to-feed ratio for bunk management or mDGS inclusion. Hot carcass weight, ribeye area, marbling score and quality grade were not affected (P ≥ 0.48) by either bunk management or mDGS inclusion. Back fat was greater (P = 0.04) for CON steers compared to LONG (1.30 vs 1.12 ± 0.05cm, respectively), but was not affected (P = 0.59) by mDGS inclusion. Steers on CON had greater (P = 0.03) yield grades compared to LONG (3.21 vs 2.96 ± 0.11, respectively). Bunk management strategy did not impact hydrogen sulfide concentrations or blood oxygen saturation (P = 0.82). Hydrogen sulfide concentrations increased (P &lt; 0.001) with increasing mDGS inclusion. Blood oxygen saturation was influenced by day of sampling (P = 0.01). Blood oxygen saturation was not affected (P = 0.07) by mDGS inclusion. The fact that ruminal hydrogen sulfide concentrations increased while blood oxygen saturation remained similar raises questions about the quantity of hydrogen sulfide and metabolic fate of excess hydrogen sulfide in the blood of ruminant animals.

The Impact

Today, the COVID-19 pandemic is one of the most pressing problems facing humanity. Therefore, reducing the population's level of infection with this virus is one of our government's main tasks.Therefore, it is necessary to isolate patients with chronic diseases as much as possible. Clients are more likely to be infected with caronavirus due to their age and the presence of underlying medical conditions.Limiting direct contact between such patients and observing healthcare professionals significantly reduces the patient's chances of contracting caronavirus.The article proposes a device design that allows for remote automatic monitoring of patients' condition being treated at home by an observing medical professional.With the proposed device's help, the patient's blood oxygen saturation level is automatically and remotely controlled. The device is built on an Arduino board.The use of the device greatly reduces the likelihood of contracting caronavirus in patients receiving home treatment.This could be one of the most important decisions in maintaining the health of the population today.

The Mean

We present the use of Extended Modified Lambert–Beer model for optical monitoring of mean blood oxygen saturation ( S m O 2) via a fitting procedure. This work focuses on the absorption characteristics of hemoglobin derivatives in the wavelength range of 520–600 nm to give the best estimates of S m O 2. The study of the feasibility of applying this analytic method to skin oximetry is via spectroscopy data collected from fingertips of four healthy volunteers both at rest and during arterial blood occlusion condition. The results revealed a decrease in the mean of mean and standard deviation of S m O 2 value of fingertips from 94.5 ± 2.19% when volunteers were at rest to 56.76 ± 5.8% during the arterial blood occlusion measurement. The larger variation in the value estimated for blood occlusion condition could be a result of differences in volunteers' physical fitness and hypertension status. These estimated S m O 2 values agreed reasonably well with the value reported in most of the previous studies. This work concluded that the proposed technique can potentially be used as a complementary technique to clinical assessment of skin grafts and burnt skin.
