Effectiveness of non-pharmacological interventions in improving sleep quality after cardiac surgery: A systematic review and meta-analysis

J Clin Nurs. 2024 Mar 13. doi: 10.1111/jocn.17115. Online ahead of print.

ABSTRACT

BACKGROUND: Sleep disturbance is highly prevalent among post-operative cardiac patients, with negative impacts on surgical recovery and rehabilitation. Post-operative pain and anxiety commonly seen in cardiac surgery patients are associated with poor sleep. Sleep medications commonly used are not ideal with prolonged usage, and non-pharmacological interventions can be good alternatives or complements.

AIM: To examine effectiveness of non-pharmacological interventions in post-operative cardiac settings on sleep quality, pain intensity and anxiety.

DESIGN: Systematic review and meta-analysis.

METHODS: PubMed, CENTRAL, Embase, CINAHL, Scopus, CNKI and ProQuest Dissertations and Theses were searched on 12 October 2022. Randomised controlled trials of non-pharmacological interventions examining sleep quality for adult post-operative cardiac patients were included. Included studies were appraised using Cochrane Risk of Bias tool version 1. Meta-analysis was conducted using RevMan version 5.4.1, and heterogeneity was assessed using I2 statistics and Cochran Q’s test.

RESULTS: Eighteen studies involving 1701 participants were identified. Coronary artery bypass graft was most common. Non-pharmacological interventions varied in types and duration. All intervention groups were compared to usual care, placebo, no interventions or active comparators. Statistically significant improvement in sleep quality (SMD = -.91, 95% CI = -1.17 to -.65) was found among intervention groups that explored cognitive behavioural therapy, relaxation techniques, exercise, massage, acupressure, aromatherapy, music, eye mask and earplugs. Pain intensity was reduced (SMD = -.63, 95% CI = -1.05 to -.20) with cognitive behavioural therapy, relaxation techniques, massage, music and eye mask. Anxiety was improved (SMD = -.21, 95% CI = -.38 to -.04) with exercise and music.

CONCLUSION: The overall use of non-pharmacological interventions can optimise sleep after cardiac surgery. Further research with greater methodological rigour is needed to investigate different intervention-related characteristics while considering potential confounders.

RELEVANCE TO CLINICAL PRACTICE: Post-operative cardiac settings can consider incorporating non-pharmacological interventions. Patients and healthcare providers can be better informed about the use of such interventions to improve sleep.

Rate of Urinary Tract Infections, Bacteremia, and Meningitis in Preterm and Term Infants

Pediatrics. 2024 Mar 13. doi: 10.1542/peds.2023-062755. Online ahead of print.

ABSTRACT

BACKGROUND AND OBJECTIVES: There are very limited data on the rate of urinary tract infections (UTI), bacteremia, and meningitis in preterm infants with fever. Many of the studies on the incidence of these infections excluded preterm infants. This study compared the rate of these infections in preterm infants born at 32-36 weeks to term infants born at 37-42 weeks.

METHODS: A multicenter observational cohort study was conducted to evaluate rates of UTI, bacteremia, and meningitis in term and preterm infants 8-60 days of age with a diagnosis of fever from 2016 through 2022 using encounter data from children’s hospitals in the Pediatric Health Information System.

RESULTS: There were 19 507 total febrile infants identified, of which 2162 were preterm and 17 345 were term. Preterm infants had a lower rate of UTI than term infants (1.8% confidence interval [CI] [1.3-2.5] vs 3.0% CI [2.7-3.2], P = .001). Preterm and term infants did not have statistically different rates of bacteremia (1.5% CI [1.3-1.7] vs 1.2% CI [0.8-1.8], P = .44) or meningitis (0.16% CI [0.1-0.2] vs 0.05% CI [0-0.2], P = .36).

CONCLUSIONS: There was no difference in the rate of bacteremia or meningitis between term and preterm infants in a large multicenter cohort of febrile infants. Preterm infants had a lower rate of UTI than term infants. This is the first multicenter study to compare UTI, bacteremia, and meningitis between term and preterm febrile infants.

Predicting locus-specific DNA methylation levels in cancer and paracancer tissues

Epigenomics. 2024 Mar 13. doi: 10.2217/epi-2023-0114. Online ahead of print.

ABSTRACT

Aim: To predict base-resolution DNA methylation in cancerous and paracancerous tissues. Material & methods: We collected six cancer DNA methylation datasets from The Cancer Genome Atlas and five cancer datasets from Gene Expression Omnibus and established machine learning models using paired cancerous and paracancerous tissues. Tenfold cross-validation and independent validation were performed to demonstrate the effectiveness of the proposed method. Results: The developed cross-tissue prediction models can substantially increase the accuracy at more than 68% of CpG sites and contribute to enhancing the statistical power of differential methylation analyses. An XGBoost model leveraging multiple correlating CpGs may elevate the prediction accuracy. Conclusion: This study provides a powerful tool for DNA methylation analysis and has the potential to gain new insights into cancer research from epigenetics.

Relevance of Polymerase Chain Reaction in Early Diagnosis of Leptospirosis

Indian J Crit Care Med. 2024 Mar;28(3):290-293. doi: 10.5005/jp-journals-10071-24649.

ABSTRACT

AIM AND BACKGROUND: Leptospirosis is common in India, especially in the southern states. Mortality is high among untreated cases. Diagnosis of leptospirosis remains a challenge in India as polymerase chain reaction (PCR), which is more sensitive than Immunoglobulin M (IgM) is not widely available. This study aimed to find out the difference in diagnostic yield with PCR and IgM in early leptospirosis.

MATERIALS AND METHODS: This retrospective, single-center study included 67 adults with laboratory-confirmed leptospirosis (IgM, PCR, or both) who presented within 7 days of symptom onset and were admitted to the intensive care unit (ICU). The difference in the diagnostic yield with PCR and IgM ELISA was studied.

RESULTS: About 77.6% of the patients tested positive by PCR and 55.2% tested positive by IgM. There was a statistically significant difference in the detection of leptospirosis by PCR and IgM (p-value = 0.036). In the subgroup of patients who presented within 3 days of onset of symptoms, PCR positivity was 90.32% whereas IgM positivity was only 25.8%.

CONCLUSION: Our study showed that the sensitivity of leptospira PCR is significantly higher than IgM in the first week of illness. It also showed that among the subset of patients who died, a majority were detected only by PCR. Since PCR is not widely available, leptospirosis remains underdiagnosed and mortality from the same is underestimated. Polymerase chain reaction, if routinely done along with IgM for all suspected cases of leptospirosis that present within the first week of illness helps in prompt diagnosis and treatment.

Effect of Buteyko Breathing Technique as an Adjunct to Routine Physiotherapy on Pulmonary Functions in Patients Undergoing Off-pump Coronary Artery Bypass Surgery: A Randomized Controlled Trial

Indian J Crit Care Med. 2024 Mar;28(3):280-285. doi: 10.5005/jp-journals-10071-24655.

ABSTRACT

BACKGROUND: Coronary artery disease (CAD) poses a substantial and increasing public health concern in India, particularly among individuals aged 20 and above. The postoperative phase following coronary artery bypass graft (CABG) surgery presents potential complications, notably impacting the pulmonary system. Emerging evidence suggests that the Buteyko breathing technique not only improves lung function but also positively influences the psychological well-being of CABG patients. This study seeks to assess the impact of the Buteyko breathing technique on pulmonary functions in individuals who have undergone off-pump CABG.

MATERIALS AND METHODS: In this randomized controlled trial, patients undergoing off-pump CABG were allocated to either the Buteyko breathing technique group (n = 35) or the control group (n = 35). The intervention group received supervised Buteyko breathing technique sessions twice daily for 15 minutes, concurrently with cardiac rehabilitation from postoperative day (POD-2 to POD-7). The control group underwent phase I cardiac rehabilitation. Outcome measures, including pulmonary function test (PFT), chest expansion, and breath-holding tests were evaluated at baseline (POD-2) and conclusion (POD-7).

RESULTS: Statistical analyses were conducted with a significance level set at p < 0.05. Both the control and intervention groups exhibited statistically significant improvements in pulmonary function, chest expansion at three levels, and breath-holding time (p = 0.0001). However, the Buteyko breathing group demonstrated a more significant improvement compared with the control group.

CONCLUSION: The integration of the Buteyko breathing technique into conventional physiotherapy proves to be a beneficial strategy, leading to improvements in pulmonary function, breath-holding duration, and chest expansion for individuals who underwent off-pump CABG surgery.

A Prospective Observational Study Comparing Oxygen Saturation/Fraction of Inspired Oxygen Ratio with Partial Pressure of Oxygen in Arterial Blood/Fraction of Inspired Oxygen Ratio among Critically Ill Patients Requiring Different Modes of Oxygen Supplementation in Intensive Care Unit

Indian J Crit Care Med. 2024 Mar;28(3):251-255. doi: 10.5005/jp-journals-10071-24652.

ABSTRACT

BACKGROUND: Intensive care unit (ICU) patients face a significant rise in mortality rates due to acute hypoxemic respiratory failure (AHRF). The diagnosis of AHRF is based on the PF ratio, but it has limitations in resource-constrained settings. Instead, the Kigali modification suggests using the oxygen saturation/fraction of inspired oxygen (SF) ratio. This study aims to correlate SF ratio and arterial oxygen pressure (PF) ratio in critically ill adults with hypoxemic respiratory failure, who required O2 therapy through different modes of oxygen supplementation.

MATERIALS AND METHODS: In an ICU, a prospective observational study included 125 adult AHRF patients receiving oxygen therapy, with data collected on FiO2, PaO2, and SpO2. The SF ratio and PF ratio were calculated, and their correlation was assessed using statistical analysis. The receiver operator characteristics (ROC) curve analysis was conducted to assess the diagnostic precision of the SF ratio in identifying AHRF.

RESULTS: Data from a total of 250 samples were collected. The study showed a positive correlation (r = 0.622) between the SF ratio and the PF ratio. The SF threshold values of 252 and 321 were established for PF values of 200 and 300, respectively, featuring a sensitivity of 69% and specificity of 95%. Furthermore, it is worth noting that the PF ratio and SF ratio are interchangeable, regardless of the type of oxygen therapy, as the median values of both the PF ratio and SF ratio displayed statistical significance (p < 0.01) in both acidosis and alkalosis conditions.

CONCLUSION: For patients with AHRF, the noninvasive SF ratio can effectively serve as a substitute for the invasive PF ratio across all oxygen supplementation modes.

Evaluation of Intravenous Infusion of Ibuprofen with Paracetamol-Morphine in Pain and Satisfaction of Patients Undergoing Supratentorial Brain Surgery

Anesth Pain Med. 2023 Nov 6;13(5):e139758. doi: 10.5812/aapm-139758. eCollection 2023 Oct.

ABSTRACT

BACKGROUND: The pain experienced following supratentorial brain surgery is usually defined as moderate to severe. Therefore, pain-management approaches, including narcotics, are an integral part of treatment regimens that cause respiratory complications or seizures, and reducing this pain level and increasing patient satisfaction is vital.

METHODS: This randomized, double-blind clinical trial study to evaluate the pain level and satisfaction in patients undergoing surgery for supratentorial brain neoplasms was performed on two groups with a sample size of 50 patients. In group I, after removal of the brain lesion (at the beginning of dura closure), 400 mg of ibuprofen solution was infused intravenously over 30 minutes. In group II, morphine 0.07 mg/kg intravenously with 1000 mg paracetamol was infused over 30 minutes. After injecting ibuprofen and paracetamol morphine, the patient’s pain level and satisfaction with the process were checked.

RESULTS: Patients’ satisfaction score in the first 6 hours in the ibuprofen group was 1.67 ± 0.72, and in the other group was 2.27 ± 0.7, which was statistically different (P-value = 0.029). The mean of VAS in the first, second, third, and fourth hours was not statistically different. In the comparative analysis of the laboratory indicators of platelet function analysis in the two groups, none of the measured items had a significant difference between the two groups in the three measurement periods (P > 0.05).

CONCLUSIONS: Administration of ibuprofen led to pain relief and patient satisfaction comparable to morphine and paracetamol, and after the surgery for supratentorial brain tumors, ibuprofen did not affect the patients’ blood clotting functions.

The Efficacy of Intradermal Injection of Botulinum Toxin Type-A on Painful Diabetic Neuropathy: A Systematic Review

Anesth Pain Med. 2023 Oct 9;13(5):e136260. doi: 10.5812/aapm-136260. eCollection 2023 Oct.

ABSTRACT

CONTEXT: Diabetes is one of the most common causes of neuropathy. Morbidity and mortality increase in patients suffering from diabetic polyneuropathy and are experienced by approximately 10 to 54% of diabetic patients. Severe pain, loss of sensation, increased risk of ulceration, and even amputation are the complications of diabetic neuropathy. Intradermal injection of botulinum toxin type-A (BTX-A) is a relatively novel method for the treatment of painful diabetic neuropathy. This method is becoming popular considering its acceptable and long-lasting pain control and minimal systemic side effects.

METHODS: This narrative systematic review aimed to evaluate the effectiveness of intradermal BTX-A injection on painful diabetic neuropathy. The queried databases included PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), ClinicalTrials.gov, Web of Science, Scopus, and Google Scholar. The final search was performed in February 2022, and no time limits were set for the search. All the relevant clinical trials were included. The inclusion criteria and search strategy were set as follows: Type of study: Randomized clinical trial (RCT) or other types of interventional studies; publication date: All published studies until February 22, 2022; sample size: No restrictions; outcomes: Effect on diabetic neuropathy pain; quality: Earning a minimum acceptable score based on critical appraisal; and language: English. The searches and article screening were performed by two independent reviewers to minimize the possibility of bias. In case of disagreement about a study, the comments of an expert (as a third person) were used to resolve the ambiguity.

RESULTS: In a review of 4 RCTs and 1 case-control study on the effectiveness of BTX-A in reducing the pain of diabetic neuropathy, 273 patients were evaluated in total. The lowest and highest number of subjects was 18 and 141. The sex distribution included 43.22% men and 56.77% women, all of whom were 47.8 to 74.8 years old. Three studies were conducted in Iran, Taiwan, and Egypt. The results of this review showed significant improvement in pain reduction, e.g., based on the Visual Analog Scale (VAS) and Neuropathic Pain Scale (NPS). A few studies evaluated sleep and psychosocial complications, and their results indicated a statistically significant improvement in the Pittsburgh sleep quality index (PSQI) and the physical subscale of the 36-Item Short Form Survey (SF-36).

CONCLUSIONS: The results of this systematic review demonstrated that intradermal injection of BTX-A causes significant and long-term (up to 12 weeks) improvement in diabetic neuropathy pain. The improvement in sleep and mental or physical functions was not consistent, and no conclusive result could be reached.

High Expression of WT1 and Low Expression of p53 in Archived Blocks of Children with Wilms Tumor in South Western Uganda

Cancer Manag Res. 2024 Mar 6;16:127-136. doi: 10.2147/CMAR.S449982. eCollection 2024.

ABSTRACT

PURPOSE: The determination of the presence or absence of anaplasia in Wilms tumor is difficult sometimes creating diagnostic errors and is worsened by the use of neoadjuvant chemotherapy, which causes cellular alterations that may mimic anaplasia. This study described the histological features of Wilms tumor and their association with WT1 and p53 expression in archived specimens in South Western Uganda.

PATIENTS AND METHODS: A series of 308 formalin-fixed paraffin-embedded tissue blocks belonging to 85 children were retrospectively recruited in the only public Histopathology laboratory in South Western Uganda. Rabbit monoclonal Anti-Wilms tumor protein antibody [(CAN-R9) IHC-56-2] ab89901 and rabbit monoclonal Anti-p53 antibody [E26] ab32389 were used to assess the expression of WT1 and p53, respectively. The expression of WT1 and p53 were reported as proportions, Chi-square was also performed to assess for associations and statistical significance was considered when the p-value was less than 0.05.

RESULTS: The median age was 3.5 with an interquartile range of (2-6) years. Mixed histology was the most common at 35.29% (95% CI:25.77-46.14). Anaplasia was present in 5.88% (95% CI:2.44-13.52) of the specimens. p53 and WT1 expressions were 13.0% (95% CI:7.25-22.04), and 41.0% (95% CI: 31.11-52.04), respectively.

CONCLUSION: Mixed-type histology is the most common histologic feature of Wilms tumor with high expression of WT1 and a low expression of p53 implying that these can be used routinely to confirm the diagnosis as well as anaplasia in South Western Uganda.

Effect of two different surgical modalities for pelvic organ prolapse on postoperative wound infection in patients: A meta-analysis

Int Wound J. 2024 Mar;21(3):e14802. doi: 10.1111/iwj.14802.

ABSTRACT

Sacrospinous ligament fixation (SSLF) is widely applied to the treatment of female pelvis organ prolapsed. Contradictory findings have already been reported in the comparison of sacrocolpopexy (SC) with SSLF. The objective of this study is to evaluate the efficacy of SC versus SSLF in treating pelvis organ prolapsed after operation. We conducted a meta-analysis of both operative approaches, including PubMed, Embase, and Cochrane Library. In this research, 822 articles were chosen from three databases, 201 were copied, and 10 were included. Among them, 7248 cases were operated on the prolapsed pelvis. It was found that SSLF surgery could significantly decrease the rate of postoperative wound infection after operation (odds ratio [OR], 0.59; 95% confidence interval [CI], 0.42-0.82; p = 0.001). No statistical significance was found among the SSLF and the SC surgery for the post-operation haemorrhage of the patient (OR, 0.81; 95% CI, 0.23-2.83; p = 0.75). No statistical significance was found among the SSLF and the SC surgery for the postoperative period of the patient’s operation (mean difference, -15.46; 95% CI, -52.87 to 21.94; p = 0.42). Applying SSLF surgery to treat pelvic prolapse in women may benefit from a reduction in the number of post-operative wound infections. However, SSLF had no statistical significance with respect to the amount of haemorrhage after operation or operation time.
