BACKGROUND

Blood pressure is an important vital sign measured not only in hypertension but also among hospitalized patients for clinical evaluation of the actual hemodynamic status. In the digital era, mercury and aneroid sphygmomanometers are being replaced by automated monitors despite lacking validation and recommendations for their use, especially in acute illness.

To compare automated and manual blood pressure measurement among hospitalized medical patients with acute illness.

A crossover design was used in a single tertiary hospital. Blood pressure was recorded from 216 participants, with 432 observations from an automated monitor (Omron HBP1120) and a mercury sphygmomanometer. Automated and manual BP recordings were done twice following the same arm sequential method. The average of the two recordings was used for comparison.

Most participants were female, elderly, obese, and had cardiac complaints. Comparing automated and manual methods, the mean difference for systolic was 1.47 ± 12.12 (p = 0.08) and 1.82 ± 10.99 (p=0.02) for diastolic. Subgroup analysis revealed that males had higher manual systolic BP than females (pairwise p-value= 0.017). Overweight and obese participants had higher automated systolic and diastolic BP (p=0.04). Overweight and obese participants had significantly higher systolic and diastolic BP regardless of the method. Significantly higher diastolic BP for different age groups and areas of admission (p=0.02) were observed from the automated method.

Automated BP monitoring showed a significant difference in diastolic BP recordings. Automated BP monitors should be used with caution, especially in interpreting diastolic BP among hospitalized patients.

BACKGROUND

Heart rate variability (HRV) is a common tool for assessing autonomic nervous system activity and monitoring training load in athletes. However, limited research has explored how HRV responds to different forms of resistance training, particularly in high-intensity intermittent sports like basketball and football.

This study aims to compare the acute HRV responses between neuromuscular and metabolic training in collegiate athletes involved in high-intensity intermittent sports.

A comparative cross-sectional study with a quasi-experimental crossover design will be employed.

Collegiate athletes will be randomly assigned to undergo both neuromuscular and metabolic training sessions with a one-week wash-out period in between. HRV data will be recorded using the Polar H10 chest strap during each session.

Descriptive statistics will summarize salient participant characteristics and HRV measurements. Inferential analysis will use paired t-tests or Wilcoxon signed-rank tests based on normality, assessed via the Kolmogorov-Smirnov test. All statistical analyses will be conducted using the IBM SPSS (ver.25) with a confidence interval set. at 95% and a critical α equal to 0.05.

Neuromuscular training is expected to elicit higher low-frequency (LF) power and an increased LF/HF ratio, reflecting greater sympathetic activation, while metabolic training is expected to show lower LF power and a decreased LF/HF ratio, indicating a more balanced autonomic response. These findings will offer insights into the differential autonomic impacts of these training modalities.

Background: Hypertension is associated with the improvement of cardiovascular disease and all-cause mortality. A healthy diet based on consuming natural foods can prevent and control hypertension. Objective: The aim of this study was to analyze the effectiveness of tomato and cucumber juice in reducing the blood pressure of hypertensive patients. Methods: The study used a quasi-experiment pretest-posttest control group design. The target population are people with hypertension Stage 1, people living in urban area - Cibiru Health Centre Work Area. Purposive sampling was used and the sample size was calculated using the average comparison formula with effect size=0.9, α=0.05, β =0.2. Forty-five subjects involved in the study were divided into three groups (15 subjects were given tomato juice, 15 subjects were given cucumber juice, and 15 subjects were given treatment with mineral water (control group)., This research used 100 grams of ripe red tomatoes, 100 grams of fresh cucumber, and 200 ml of water. The data collected were patient characteristics and blood pressure. The ANOVA analysis test and the Bonferroni Post Hoc test were used to analyze the data. Results: The results of the study showed a difference in blood pressure reduction in each group. The decrease in systolic blood pressure in the tomato juice group was 7.3+3.1, the cucumber juice group was 4.2+3.3, and the control group was -0.0+2.5 (p=0.0001). The decrease in diastolic blood pressure in the group given tomato juice was 9.2+3.1, the group given cucumber juice was 7.6+3.4, and the control group was 0.4+2.1 (p=0.0001). Conclusion There is a difference in blood pressure reduction between the group given tomato juice and the control group, and there is a difference in blood pressure between the group given cucumber juice and the control group.

BACKGROUND Hypertension is the most common risk factor for cardiovascular disease in the Philippines. Despite the availability of antihypertensive medications that are effective, safe, and tolerated by Filipino patients, the numbers of uncontrolled hypertensives are still increasing. Several factors play in the poor control of blood pressure, particularly resistant hypertension and hyperactive sympathetic nervous system. Renal denervation therapy is a novel device that has been shown to lower blood pressure in patients with resistant and difficult-to-treat hypertension and is deemed safe in clinical trials. A Philippine Working Group composed of specialists in cardiology, hypertension, vascular surgery, and clinical epidemiology has come up with consensus statements in identifying patients who will benefit from the procedure. Locally, there is a need to have hypertension centers treating uncontrolled and resistant hypertension and offer renal denervation therapy to appropriate Filipino patients.

Introduction: Laparoscopic Cholecystectomy uses carbon dioxide (CO2) which affects the respiratory, cardiovascular and renal system. The residual CO2 induces phrenic nerve irritation, manifesting as shoulder and abdominal pain. Recruitment maneuvers opens the lungs and helps expelling this residual carbon dioxide. However, there are limited studies on its role to hemodynamics especially in patients undergoing abdominal laparoscopic procedures. Methods: Sixty patients (51 15.1) scheduled for laparoscopic cholecystectomy under General Endotracheal Anesthesia were randomly allocated to two groups. The control group (Group C) underwent standard laparoscopic cholecystectomy procedures. The experimental group (Group R) was placed in a Trendelenburg and was given 4-5 manual pulmonary inflations at a pressure of 40cmH20. The blood pressure, heart rate, respiratory rate and oxygen saturation, as well as the post operative site pain and shoulder pain were measured using the Numerical Pain Scale (NPS) were monitored at 0, 1 and 2 hours post operatively. Results: The demographics and preoperative vital signs were comparable. The mean systolic blood pressure [119.5 vs 131.5; p=0.002], mean arterial pressure [91.8 vs 95.3; p=0.049], heart rate [74.9 vs 87.5; p <0.001] and respiratory rate [15.7 vs 16.2; p=0.02] were all differrent only during the immediate post operative period. The mean shoulder pain was lower in Group R immediately [1.9 ± 1.2; p=0.01] and 1 hour after surgery [0.7 ± 0.8; p=0.01]. Conclusion Recruitment maneuver significantly reduces the shoulder pain scores after laparoscopic cholecystectomy. It causes a decrease in blood pressure, heart rate and mean arterial pressure in the immediate post operative period.

OBJECTIVE: To explore the feasibility of snuff pot arterial pressure measurement for patients undergoing routine elective surgery during anesthesia. METHODS: A prospective randomized controlled trial was conducted. Patients undergoing elective surgery admitted to the Handan Hospital of Traditional Chinese Medicine from June 1, 2020 to June 1, 2022 were enrolled. Patients who needed arterial pressure measurement for hemodynamic monitoring were randomly divided into routine radial artery puncture group and snuff pot artery puncture group with their informed consent. The patients in the routine radial artery puncture group were placed a catheter at the styloid process of the patient's radius to measure pressure. In the snuff pot artery puncture group, the snuff pot artery, that was, the radial fossa on the back of the hand (snuff box), was selected to conduct the snuff pot artery puncture and tube placement for pressure measurement. The indwelling time of arterial puncture catheter, arterial blood pressure, and complications of puncture catheterization of patients in the two groups were observed. Multivariate Logistic regression analysis was used to screen the relevant factors that affect the outcome of arterial catheterization. RESULTS: Finally, a total of 252 patients were enrolled, of which 130 patients received routine radial artery puncture and 122 patients received snuff pot artery puncture. There was no statistically significant difference in general information such as gender, age, body mass index (BMI), and surgical type of patients between the two groups. There was no significant difference in the indwelling time of artery puncture catheter between the routine radial artery puncture group and the snuff pot artery puncture group (minutes: 3.4±0.3 vs. 3.6±0.3, P > 0.05). The systolic blood pressure (SBP) and the diastolic blood pressure (DBP) measured in the snuff pot artery puncture group were significantly higher than those in the conventional radial artery puncture group [SBP (mmHg, 1 mmHg ≈ 0.133 kPa): 162.3±14.3 vs. 156.6±12.5, DBP (mmHg): 85.3±12.6 vs. 82.9±11.3, both P < 0.05]. There was no statistically significant difference in the incidence of complications such as arterial spasm, arterial occlusion, and pseudoaneurysm formation between the two groups. However, the incidence of hematoma formation in the snuff pot artery puncture group was significantly lower than that in the conventional radial artery puncture group (2.5% vs. 4.6%, P < 0.05). Based on the difficulty of arterial puncture, multivariate Logistic regression analysis showed that gender [odds ratio (OR) = 0.643, 95% confidence interval (95%CI) was 0.525-0.967], age (OR = 2.481, 95%CI was 1.442-4.268) and BMI (OR = 0.786, 95%CI was 0.570-0.825) were related factors that affect the outcome of arterial catheterization during anesthesia in patients undergoing elective surgery (all P < 0.05). CONCLUSIONS Catheterization through the snuff pot artery can be a new and feasible alternative to conventional arterial pressure measurement.

OBJECTIVE: To investigate the predictive value of pulse infusion index (PPI) in the short-term prognosis of patients with sepsis-induced acute kidney injury (AKI). METHODS: A retrospective cohort study was conducted. The clinical data of patients with sepsis-induced AKI admitted to intensive care unit (ICU) of the First Affiliated Hospital of Soochow University from July 2021 to December 2022 were enrolled. The basic information of the patients were collect, including age, gender, site of infection, underlying disease, mean arterial pressure (MAP) and heart rate (HR) at admission, as well as the use of mechanical ventilation and vasoactive drugs, and norepinephrine (NE) dosage. Laboratory indicators, sequential organ failure assessment (SOFA) score and PPI within 24 hours of admission were also recorded, and the patient's prognosis during ICU hospitalization was also recorded. The differences in clinical data between the patients of two groups with different prognosis were compared. Spearman correlation method was used to analyze the correlation between PPI and SOFA score. Binary multivariate Logistic regression analysis was used to screen independent risk factors for death during ICU hospitalization in sepsis patients with AKI. Receiver operator characteristic curve (ROC curve) was plotted to evaluate the predictive value of PPI for the short-term prognosis of patients with sepsis-induced AKI. RESULTS: A total of 102 patients with sepsis-induced AKI were enrolled, of which 70 patients in the survival group and 32 patients in the death group, with ICU mortality of 31.4. Compared with the survival group, SOFA score, HR, procalcitonin (PCT), serum creatinine (SCr), and NE dosage in the death group were significantly increased [SOFA score: 11.22±2.48 vs. 8.56±2.01, HR (bpm): 103.80±12.47 vs. 97.41±9.73, PCT (μg/L): 9.22 (5.24, 17.84) vs. 6.19 (3.86, 7.71), SCr (μmol/L): 163.2 (104.7, 307.9) vs. 125.5 (89.3, 221.0), Lac (mmol/L): 2.81 (1.95, 4.22) vs. 2.13 (1.74, 2.89), NE usage (μg×kg^-1×min^-1): 0.7 (0.4, 1.1) vs. 0.5 (0.2, 0.6), all P < 0.05], while PPI was significantly lower than that in survival group [0.83 (0.42, 1.55) vs. 1.70 (1.14, 2.20), P < 0.01]. Spearman correlation analysis showed that based on SOFA score, PPI was closely related to the severity of patients with sepsis-induced AKI (r = -0.328, P < 0.05). Binary multivariate Logistic regression analysis showed that PPI [odds ratio (OR) = 0.590, 95% confidence interval (95%CI) was 0.361-0.966, P = 0.002], SOFA score (OR = 1.406, 95%CI was 1.280-1.545, P < 0.001), PCT (OR = 2.061, 95%CI was 1.267-3.350, P = 0.006) were independent risk factors of the short-term prognosis of patients with sepsis-induced AKI. ROC curve analysis showed that the area under the ROC curve (AUC) of PPI for death during ICU hospitalization in patients with sepsis-induced AKI was 0.779 (95%CI was 0.686-0.855, P < 0.001), which superior to PCT (AUC = 0.677, 95%CI was 0.577-0.766, P = 0.004), and similar to SOFA score (AUC = 0.794, 95%CI was 0.703-0.868, P < 0.001). When the cut-off value of PPI was 0.72, the sensitivity was 50.0%, and the specificity was 97.1%. CONCLUSIONS PPI has a good predictive value for the short-term prognosis of patients with sepsis-induced AKI during ICU hospitalization.
