Efficacy of Massage on Pain Intensity in Post-Cesarean Women: a Systematic Review and Meta-Analysis.

Background: Cesarean section is a common surgical procedure that may be considered a safe alternative to natural birth and helps to resolve numerous obstetric conditions. Still, the Cesarean section is painful; relieving pain after a Cesarean section is crucial, therefore analgesia is necessary for the postoperative period. However, analgesia is not free of complications and contraindications, so massage may be a cost-effective method for decreasing pain post-Cesarean. Our study aims to determine the massage role in pain intensity after Cesarean sections. Methods: We searched five electronic databases for relevant studies. Data were extracted from the included studies after screening procedures. We calculated the pooled mean difference (MD) and standardized mean difference (SMD) for our continuous outcomes, using random or fixed-effect meta-analysis according to heterogenicity status. Interventional studies were assessed for methodological quality using the Cochrane risk-of-bias assessment tool, while observational studies were assessed using the National Institutes of Health's tools. Results: Our study included 10 RCTs and five observational studies conducted with over 1,595 post-Cesarean women. The pooled MDs for pain intensity considering baseline values either immediately or post 60-90 minutes were favoring the massagegroup over the control group as follows:(stand. MD = -2.64, 95% CI [-3.80, -1.48], p >.00001; MD = -2.64, 95% CI [-3.80, -1.48], p >.00001, respectively). While pooled MDsregarding post-intervention only eitherimmediately or post 60-90 minutes were:(stand. MD = -2.04, 95% CI [-3.26, -0.82], p =.001; stand. MD = -2.62, 95% CI [-3.52, -1.72],p > .00001, respectively). Conclusion: Our study found that using massage was superior to the control groups in decreasing pain intensity either when the pain was assessed immediately after or 60-90 minutes post-massage application.

Impact of indirect bilirubin and uric acid on outcomes of sepsis-associated acute kidney injury (sAKI).

BACKGROUND: Acute kidney injury (AKI) is one of the most frequent pathophysiologic disorders encountered in hospitalized patients, with sepsis frequently implicated in pathogenesis. Reactive oxygen species (ROS) seem to have a significant contribution to sepsis-induced AKI. Proposed mechanisms include induction of cell membrane lipid peroxidation, protein denaturing, and direct DNA damage, all of which have deleterious effect. These changes constitute oxidative injury to the kidneys. OBJECTIVE: To evaluate the antioxidant actions of indirect bilirubin and uric acid on outcomes of sepsis-associated AKI. METHODS: Ninety-eight patients admitted to the intensive care unit (ICU), at a large tertiary center, with sepsis and AKI were evaluated for serum levels of uric acid, bilirubin (primarily indirect), and procalcitonin. The primary endpoints studied were the need for hemodialysis and death. RESULTS: Thirty-two (33%) patients developed AKI requiring hemodialysis (HD). These patients had higher SOFA scores (p < 0.001) and lower levels of indirect bilirubin (p < 0.001) compared to those not requiring HD. There was no statistically significant difference in serum uric acid levels. Logistic regression analysis identified creatinine level, total and indirect bilirubin levels, and leukocyte count as significant predictors of patient death. CONCLUSION: Higher leukocyte counts and creatinine levels were independently associated with poor outcomes in ICU patients with sepsis. Additionally, lower indirect bilirubin levels were also noted to be associated with similar outcomes. The latter provides insights into oxidative stress as a major player in the pathogenesis of sepsis-induced AKI, with a potential protective role of indirect bilirubin.

Gender Difference in Perceived Symptoms and Laboratory Investigations in Suspected and Confirmed COVID-19 Cases: A Retrospective Study.

BACKGROUND: Evaluating gender-specific effects of COVID-19 is important to develop effective therapeutic strategies. The aim of this study was to explore gender difference in perceived symptoms and laboratory investigations in suspected and confirmed cases. METHODS: This is a retrospective study that included data from suspected COVID-19 patients during the first wave of the pandemic. Participants using the phone triaging system at Kasralainy outpatient clinics were included. The analyzed data included patient history and results of nasopharyngeal swab and laboratory data. RESULTS: Out of 440 COVID-19 suspected cases, 56.36% were females. The perceived COVID-19 symptoms showed no significant gender difference in suspected cases while in confirmed cases females were 4 times more likely to complain of cough [OR (95% CI) 3.92 (1.316-11.68), P-value .014] and 5 times more likely to experience loss of smell or taste [OR (95% CI) 4.84 (1.62-14.43), P-value .005]. Laboratory markers revealed high levels of aspartate aminotransferase, alanine aminotransferase, blood urea, serum creatinine, creatine kinase, and serum ferritin in males and this was statistically significant (P-value <.001) in suspected and confirmed cases. Females confirmed with COVID-19 were 80%, 97%, and 97% less likely to have high levels of ALT, creatin kinase, and serum ferritin [OR (95% CI) 0.20 (0.07-0.54), 0.07 (0.01-0.38), and 0.07 (0.01-0.90), P-value .002, .002, and .041, respectively]. CONCLUSION: Gender differences were found in laboratory markers in COVID-19 suspected and confirmed cases and in perceived symptoms in confirmed cases.

Methylation degree of metalloproteinase inhibitor RECK gene: Links to RECK protein level and hepatocellular carcinoma in chronic HCV infection patients.

The RECK gene, a tumor suppressor gene, inhibits angiogenesis, invasion, and tumor metastasis. Epigenetic regulation of the RECK gene constitutes a potent approach to the molecular basis of liver malignancy. This study aims to evaluate the promoter methylation status of the RECK gene and its serum level in patients with hepatitis C virus (HCV)-related hepatocellular carcinoma (HCC) and the potential association of RECK gene methylation with clinical criteria of HCC. One hundred and fifty-five subjects were included (healthy control [55], chronic HCV patients [55], HCV-related HCC patients [45]). The methylation status of the RECK gene promoter and serum RECK level were investigated by methylation-specific PCR and enzyme-linked immunosorbent assay techniques, respectively. RECK gene promoter hypermethylation was recorded in 46.7% of HCC patients, and 10.9% of HCV patients, but not in control subjects (0%). It was related to RECK protein level, varices, edema, ascites, lymph node metastasis, vascular invasion, and the largest diameter of focal lesions. Meanwhile, it was not associated with focal lesion number nor distant metastasis of HCC. In conclusion, RECK gene promoter hypermethylation is linked to HCV genotype-4-related HCC. Moreover, different degrees of RECK gene promoter methylation are associated with serum RECK level, lymph node metastasis, and vascular invasion, which could prove its pathogenic role in hepatocarcinogenesis in chronic HCV-infected patients.

Measurability and reliability of assessments of root length and marginal bone level in cone beam CT and intraoral radiography: a study of adolescents.

OBJECTIVES: To evaluate measurability and reliability of measurements of root length and marginal bone level in CBCT, periapical (PA) and bitewing (BW) radiographs. METHODS: CBCT of both jaws, PA of maxillary incisors and posterior BW radiographs of 10 adolescents (mean age 13.4) were selected. The radiographs comprised part of the baseline examinations of a trial of orthodontic treatment. Six raters assessed measurability and measured root length and marginal bone level. Three raters repeated their assessments. Measurability was expressed as frequency of interpretable sites and reliability as intraclass correlation coefficient (ICC). RESULTS: Measurability was 100 % in CBCT and 95 % in PA of maxillary incisors for root length measurements. For marginal bone level, measurability was 100 % in CBCT, 76 % in PA and 86 % in posterior BW. Mean ICC for interrater reliability for root length measurements in CBCT was 0.88 (range 0.27-0.96 among different teeth) and 0.69 in PA of maxillary incisors. For marginal bone level measurements, mean ICC was 0.4 in CBCT, 0.38 in PA of maxillary incisors and 0.4 in posterior BW. Intrarater reliability varied among methods, root length or marginal bone level and among raters, except for root length measurements in CBCT, which presented high reliability (above 0.8) for all raters. CONCLUSIONS: As measurability and reliability were high for root length measurements in CBCT, this may be the method of choice for scientific analyses in orthodontics. For clinical praxis, we recommend PA following the "as low as diagnostically acceptable" principle, as clinical decisions seem to be influenced only when severe root resorption occurs.

The impact of premature birth on the permanent tooth size of incisors and first molars.

BACKGROUND: Scientific evidence is insufficient to answer the question of whether premature birth causes altered tooth-crown dimensions. OBJECTIVE: To evaluate permanent tooth-crown dimensions in prematurely born children and to compare the findings with full-term born controls. SUBJECTS AND METHODS: Preterm children of 8-10 years of age were selected from the Swedish Medical Birth Register. One group consisted of 36 extremely preterm children (born before the 29th gestational week); the other group included 37 very preterm children (born during gestational weeks 29-32). The preterm children were compared with 41 matched full-term born children. Clinical examination and study casts were performed on all children. Permanent maxillary and mandibular first molars, central incisors, and laterals were measured with a digital sliding caliper on study casts. The tooth-crowns were measured both mesio-distal and bucco-lingual. RESULTS: Both the mesio-distal and bucco-lingual measurements in the maxillary and mandibular first molars had a significantly smaller width in the extremely preterm group compared with the full-term group. The central incisors and lower laterals were significantly smaller mesio-distally in the extremely preterm group compared to the full-term group. A reduction in tooth size of 4-9% was found between the extremely preterm group and the full-term group for both boys and girls. The maxillary first molars and mandibular left first molar were also smaller mesio-distally in the extremely preterm group compared to the very preterm group. The results indicate that the more preterm the birth, the smaller the tooth-crown dimensions. Independent of gestational age girls had generally smaller teeth than boys. CONCLUSION: Premature birth is associated with reduced tooth-crown dimensions of permanent incisors and first molars.

FLT3 Internal Tandem Duplication Mutation, cMPL and CD34 Expressions Predict Low Survival in Acute Myeloid Leukemia Patients.

OBJECTIVES: To detect FMS-like tyrosine kinase-3 internal tandem duplicate (FLT3 ITD) mutation, Myeloproliferative leukemia virus oncogene (cMPL) and Ephrin A 4 receptor (EphA4) expressions in Acute myeloid leukemia (AML) and their correlation to patient's clinicopathological characteristics and survival. METHODS: RNA was extracted from blood samples of 58 AML patients (39 adults and 19 children) and 20 age and sex matched controls. FLT3 ITD mutation, cMPL and EphA4 expression was studied using RT-PCR and correlated to the clinical and survival data of the patients. RESULTS: FLT3 ITD mutation, cMPL and EphA4 expression was positive in 35.9%, 76.9% and 56.4% of adult AML patients respectively and in 15.8%, 47.4% and 36.8% of pediatric AML patients respectively. 76.9% of adult and 89.5% of pediatric patients expressed CD33. 64.1 % of adults and 42.1% of children expressed CD34. CD34 expression was significantly associated with both FLT3 ITD mutation and cMPL expression. CD34, FLT3 and cMPL negative cases have significantly higher overall survival than positive cases. CONCLUSION: CD34 expression is significantly associated with both FLT3 ITD mutation and cMPL expression which could be used as a marker for low survival. Normal FLT3 and negative expression of CD34 and cMPL may predict a longer overall survival. Further studies are needed to investigate the mechanism that may correlate CD34 to both markers.

Interleukin-23R gene polymorphism in pediatric Egyptian patients with primary immune thrombocytopenia.

Primary immune thrombocytopenia is an acquired autoimmune disorder caused by the production of antiplatelet antibodies. These autoantibodies opsonize platelets for splenic clearance, resulting in low levels of circulating platelets. The current case-control study aimed at detecting the frequency of interleukin-23 receptor rs1884444 single nucleotide polymorphism in Egyptian children with primary immune thrombocytopenia and its possible role as a genetic marker for disease risk. Interleukin-23 receptor rs1884444 single nucleotide polymorphism was studied in 50 patients with primary immune thrombocytopenia and 100 healthy age and sex-matched controls by polymerase chain reaction amplification of the target gene followed by allele-specific restriction enzyme digestion. Regarding the distribution of the genotypes of the interleukin-23 receptor rs1884444 polymorphism, no statistically significant difference was found between cases and control groups. The variant genotypes (GT/TT) frequency was 10% in primary immune thrombocytopenia cases versus 7% in the control groups [P value = 0.755, odds ratio (OR): 0.326, 95% confidence interval (CI): 0.099-1.076]. Similarly, no difference was found between acute and chronic cases. The variant genotypes GT/TT frequency was 10.7% in acute versus 9.1% in chronic primary immune thrombocytopenia (P value = 0.849). The variant genotypes GT/TT were not found to be a risk factor for acute primary (P value = 0.807, OR: 0.641, 95% CI: 0.16-2.563) or chronic primary immune thrombocytopenia (P value = 0.914, OR: 0.762, 95% CI: 0.153-3.797). Our study suggests the possibility that interleukin-23 receptor gene polymorphism may not contribute to the susceptibility of development of primary immune thrombocytopenia in Egyptian children.
