Procalcitonin and Proinflammatory Cytokines in Early Diagnosis of Bacterial Infections after Bronchoscopy

BACKGROUND: Fiberoptic bronchoscopy (FOB) guided bronchoalveolar lavage (BAL) remains as the chief diagnostic tool in respiratory disorders. 1.2-16% of patients frequently experience fever after bronchoscopy. To exclude the need for multiple antibiotic prescribing in patients with post-bronchoscopy fever, the presence of the self-limiting inflammatory responses should be excluded. AIM: The current study was conducted to test the serum of patients undergoing bronchoscopy for some proinflammatory cytokines including Tumor Necrosis Factor-alpha (TNF-ɑ), Interleukin-1beta (IL-1β), Interleukin-8 (IL-8) and Interleukin-6 (IL-6) and the value of Procalcitonin (PCT). MATERIAL AND METHODS: Current case-control study was conducted at the National Research Institute of Tuberculosis and Lung Disease in Iran. Nineteen patients (48.72%) that attended with a reasonable sign for a diagnostic bronchoscopy from January 2016 to December 2017 were included in the case group. The control group consisted of 20 patients who underwent a simple bronchoscopy and without FOB-BAL. The laboratory findings for PCT concentrations and cytokine levels in the three serum samples (before FOB-BAL (t0), after 6 hr. (t1), and at 24 hr. past (t2) FOB-BAL) were compared between two groups. RESULTS: The frequency of post-bronchoscopy fever was 5.12, and the prevalence of post-bronchoscopy infectious fever was 2.56%. PCT level was considerably higher in the patient with a confirmed bacterial infection when compared to other participants (p-value < 0. 05). Interestingly, IL-8 level in the bacterial infection proven fever patient was higher than in other patients (p < 0.001). IL-8 levels displayed a specificity of 72.7% and a sensitivity of 100%, at the threshold point of 5.820 pg/ml. PCT levels had a specificity of 84% and a sensitivity of 81%, at the threshold point of 0.5 ng/ml. CONCLUSION: The present findings show that in patients with fever after bronchoscopy, PCT levels and IL-8 levels are valuable indicators for antibiotic therapy, proving adequate proof for bacterial infection. The current findings also illustrate that to monitor the serum levels of PCT and proinflammatory cytokines in the patients undergoing FOB-BAL, the best time is the 24-hour postoperative bronchoscopy.

Objective: Poor ovarian response (POR) refers to a subnormal follicular response that leads to a decrease in the quality and quantity of the eggs retrieved after ovarian stimulation during assisted reproductive treatment (ART). The present study investigated the associations of multiple variants of the estrogen receptor 2 (ESR2) and follicle-stimulating hormone receptor (FSHR) genes with POR in infertile Jordanian women undergoing ART.Methods: Four polymorphisms, namely ESR2 rs1256049, ESR2 rs4986938, FSHR rs6165, and FSHR rs6166, were investigated in 60 infertile Jordanian women undergoing ART (the case group) and 60 age-matched fertile women (the control group), with a mean age of 33.60±6.34 years. Single-nucleotide polymorphisms (SNPs) were detected by restriction fragment length polymorphism and then validated using Sanger sequencing.Results: The p-value of the difference between the case and control groups regarding FSHR rs6166 was very close to 0.05 (p=0.054). However, no significant differences were observed between the two groups in terms of the other three SNPs, namely ESR2 rs1256049, ESR2 rs4986938, and FSHR rs6165 (p=0.561, p=0.433, and p=0.696, respectively).Conclusion: The association between FSHR rs6166 and POR was not statistically meaningful in the present study, but the near-significant result of this experiment suggests that statistical significance might be found in a future study with a larger number of patients.

Abstract Background In COVID 19 era, the literature on e-learning, or particularly m-learning, has considerably increased focusing on the subject of medical knowledge transfer. Considering the importance of orthopedic knowledge for general practitioners and the inadequacy of the orthopedics internship duration in Mashhad University of Medical Sciences (MUMS), we have developed and investigated a smartphone orthopedic educational application named “Orthobox”. Methods In a quasi-clinical before-after trial study, we investigated the benefits of Orthobox application for medical interns attending MUMS orthopedic departments. A total of 120 students (64 and 56 students in control and case groups respectively) were recruited. The application consists of five main parts of medication, common order samples, common prescriptions, cast and splint types, and educational movies. Students who passed the course without getting access to the application (control group) and students who were also using application during the course (case group) were defined, and comparison was done between them objectively through final exam score comparison and subjectively through Visual Analogue Scale (VAS) questionnaire score comparison. Besides, using case group students’ activity report provided by the application panel, correlational analysis was done on their amount of activity on each of the main parts of the application and the corresponding question exam and VAS score separately. Results The case group of the study generally achieved higher final exam scores, mainly on Order question score (P value<0.001). Total VAS scores were also greater in case group (P value =0.001). It has also been identified that there is a notable positive trend between student’s amount of usage of the application and their final exam scores through correlational analysis. This correlation was not significant about students’ application visit numbers and VAS scores. Conclusion These results suggest that m-learning has got the potential to improve students’ medical knowledge and skills by organizing must-to-learn content specified for intern students of orthopedics on one hand, and cause more satisfaction in students about their education on the other hand. Trial registration This study was not registered because it is a quasi-clinical trial study. Level of evidence Level III (Evidence obtained from well-designed controlled trials without randomization (i.e. quasi-experimental).

The incidences of pneumonia in infants Become the second highest cause mortality before reaching the age of 5 years and a health problem in Indonesia. The family of smoking and smoke from burning mosquito coils are the triggers for air pollution, which can lead to pneumonia in infants. The study aims to analyze the relationship between family smoking habits and the use of mosquito coils with the incidence of pneumonia in under-fives. The method of research applied analytic observational research using a case-control study approach. The number of samples in this study was 87 under-fives in the case group and 87 under-fives in the control group. Sampling was conducted by non-probability sampling. A questionnaire was used as a data collecting instrument. Data analysis used chi-square and multiple logistic regression. The results of this study Showed that there was a relationship between family smoking habits and the use of mosquito coils with the incidence of pneumonia in infants. In addition, there were other variables that had a relationship with the incidence of pneumonia in under-fives namely smoking location (OR = 3,046; 95% CI: 1429-6492, p = 0.003), the number of cigarettes (OR = 7.105 ; 95% CI: 3079-16394, p = 0.000), and length of time with smokers (p = 0.000). On the other hand, the variables of father smoker status and the frequency of using mosquito coils were not related to the incidence of pneumonia in under-fives (p value 0.05). It is concluded that family smoking habits, use of mosquito coils, the location of smoking, and number of cigarettes, and length of time together with smokers were risk factors associated with the incidence of pneumonia in toddlers

Objectives: This study was aimed to assess salivary sodium and potassium concentrations in patients with fixed orthodontic appliances. Methods: In this case-control study, saliva samples (5 cc) were collected from 13 patients with fixed orthodontic appliances before, and 1 week, 1 month and 3 months after the beginning of the orthodontic treatment using the spitting method. Saliva samples were also collected from 10 healthy individuals as controls. The saliva samples were centrifuged at 3000 rpm for 10 minutes and the salivary sodium and potassium concentrations were measured by spectrophotometry. Data were analyzed using independent and paired t-tests. P-value < 0.05 was considered as significant. Results: The salivary sodium and potassium concentrations were almost the same in both groups at baseline (P > 0.05). A significant reduction in sodium and an increase in potassium levels were noted in the case group at 1 week compared with baseline (P < 0.001). At 1 week, the potassium concentration was significantly higher and the sodium concentration was significantly lower in the case group (P < 0.01). The salivary sodium significantly increased while the salivary potassium significantly decreased at 1 month compared with 1 week (P < 0.001). The differences with the control group were also significant (P < 0.05). No significant differences were noted between the two groups at 3 months (P > 0.05). Conclusions: Time has a significant effect on the release profile of sodium and potassium ions from orthodontic appliances. The salivary sodium and potassium concentrations returned to their normal pretreatment values within 3 months after the start of fixed orthodontic treatment.

Objective Neonatal sepsis is one of the most important causes of neonatal morbidity and mortality. Symptoms and signs of neonatal sepsis can be silent; therefore, laboratory investigation is necessary in cases of doubt or if there are risk factors. Early diagnosis is important for early intervention and treatment. The most valuable method for diagnosis is blood culture; however, false positivity due to contamination or false negativity despite ongoing fatal bacterial infections can be seen. Pentraxin 3 is a prototype of the long pentraxin family. It has some differences from C-reactive protein (CRP) in terms of gene organization and localization and production site. It is effective in the early phase of inflammation and it is detected as an early marker of sepsis in adults. The aim of this study was to investigate whether pentraxin 3 can be used as a marker in neonatal sepsis. Materials and Methods Thirty newborns with suspected sepsis with antenatal history or the presence of clinical signs of sepsis, such as hypo/hyperthermia, feed intolerance, lethargy, hypotonia, irregular cardiac rhythms, bradycardia, cyanosis, apnea, respiratory distress, or metabolic acidosis, were enrolled in the study as a case group, and 28 healthy newborns were included as a control group. Serum pentraxin 3, procalcitonin, CRP, and hemogram in the study group and serum procalcitonin and pentraxin in the control group were examined. Results Serum pentraxin 3 (pg/mL) and serum procalcitonin (ng/mL) levels were 2,273.82 ± 1,260.75 and 0.86 ± 0.52 in the case group and 957.41 ± 268.00 and 0.19 ± 0.18 in the control group (p < 0.001 for both), respectively. Conclusion The present study showed that serum pentraxin 3 levels may be a useful marker in the diagnosis of neonatal sepsis.
