The Impact of Cefepime and Ampicillin/Sulbactam on Preventing Post-Cesarean Surgical Site Infections, Randomized Controlled Trail.

Over the previous three decades, the rate of caesarean sections performed worldwide has grown exponentially. In comparison to a vaginal birth, the risk of all postpartum infections is higher with a cesarean section. One of the key factors contributing to maternal morbidity is the development of infectious complications in the surgical site after a caesarean section. The primary goal of the research was to compare the efficiency of using ampicillin/sulbactam (AMS) and cefepime (CEF) to reduce the incidence of surgical site infections (SSI) following caesarean delivery. This prospective randomized study was conducted among 200 pregnant women scheduled for elective cesarean section. They were collected from the Obstetrics and Gynecology department of Beni-Suef University Hospital, and then they were randomly assigned into two groups. Group (A) received cefepime 30 min before and 12 h after cesarean delivery, while group (B) received ampicillin/sulbactam 30 min before and 12 h after cesarean delivery. The groups were matched regarding the baseline women characteristics. Comparing the cefepime to the ampicillin/sulbactam revealed that the cefepime significantly decreased superficial SSI from 27% to 14% (0.023). A significant decrease was observed in deep SSI with cefepime compared to ampicillin/sulbactam from 24% to 13% (p-value 0.045). Interestingly, when the cefepime was compared to the ampicillin/sulbactam, we noted that the incidence of endometritis significantly decreased from 13% to 5% (p = 0.048). A noted decrease in post-operative fever in cefepime as compared to ampicillin/sulbactam from 18% to 13% (p-value = 0.329). Receiving prophylactic cefepime pre- and post-cesarean delivery significantly decreases post-operative wound infection and endometritis.

The impact of mindfulness-based stress reduction on psychological health among patients with chronic diseases during COVID-19 outbreak lockdown.

Background: The emergence of COVID-19 has spurred a wide range of psychological morbidities. However, its influence on a vulnerable population with chronic conditions is less addressed. Therefore, this study aimed to investigate the psychological health among patients with chronic diseases during the elevated psychiatric distress associated with the outbreak and examine the efficacy and feasibility of mindfulness-based stress reduction intervention (MBSR). The study involved 149 participants recruited from university hospital outpatient clinics. Patients were allocated into two groups: MBSR training program and control group. Standardized questionnaires were administered to assess depression, anxiety and stress prior to the MBSR program and at completion of the training after 8 weeks. Results: The results showed that MBSR intervention improved psychological distress and decreased the mean scores of depression, anxiety and stress. Conclusions: Mindfulness training program based on audio and smartphone was feasible and effective when it was applied to patients with chronic diseases and showed positive impact on negative psychological stress domains. These findings pave the way for the integration of psychological support for patients with chronic illnesses in clinical settings.

Perceptions, Knowledge, and Experiences of Using Face Masks among Egyptian Healthcare Workers during the COVID-19 Pandemic: A Cross-Sectional Study.

Using face masks appropriately is important for preventing the community spread of respiratory infections. A cross-sectional study was conducted to evaluate the knowledge level and experience of using face masks between healthcare teams to protect them and limit the spread of COVID-19 infection. A structured questionnaire was distributed to 228 healthcare members in July-December 2021. It was divided into two sections and consisted of 29 questions for a total possible score of 0 to 29. The first section was related to perceptions and knowledge about face masks (13 items); the second was related to the experience of using face masks (16 items). The average score of this questionnaire was 23.21/29 with respect to the knowledge about face masks and their proper use techniques. The healthcare team studied had satisfactory knowledge about face mask use techniques, and the study shed light on their unsatisfactory practices. Following instructions is very vital to protecting the person wearing the mask and preventing the spread of infection during health care by blocking droplets produced by speaking or coughing. Providing the healthcare teams with knowledge and experience about how to use face masks during the pandemic is critical to increase their awareness and practice in using face masks and prevent the infection from spreading.

Common viral and bacterial avian respiratory infections: an updated review.

Many pathogens that cause chronic diseases in birds use the respiratory tract as a primary route of infection, and respiratory disorders are the main leading source of financial losses in the poultry business. Respiratory infections are a serious problem facing the poultry sector, causing severe economic losses. Avian influenza virus, Newcastle disease virus, infectious bronchitis virus, and avian pneumovirus are particularly serious viral respiratory pathogens. Mycoplasma gallisepticum, Staphylococcus, Bordetella avium, Pasteurella multocida, Riemerella anatipestifer, Chlamydophila psittaci, and Escherichia coli have been identified as the most serious bacterial respiratory pathogens in poultry. This review gives an updated summary, incorporating the latest data, about the evidence for the circulation of widespread, economically important poultry respiratory pathogens, with special reference to possible methods for the control and prevention of these pathogens.

Impact of n-3 polyunsaturated fatty acid intake in pregnancy on maternal health and birth outcomes: systematic review and meta-analysis from randomized controlled trails.

BACKGROUND: Maternal omega-3 consumption during pregnancy has been positively linked with a positive impact on maternal health and fetal growth. However, the results of individual studies are inconsistent and conflicting. OBJECTIVE: Examine the effect of supplementation with DHA, and/or EPA, and/or ALA throughout pregnancy on offspring's growth and pregnancy outcomes. DESIGN: A systematic review and meta-analysis. POPULATION: Pregnant women. METHODS: According to (PRISMA) statement and the Cochrane Handbook guidelines. Human trials (RCT or quasi-RCT) which involved oral omega-3 supplementation at least twice a week during pregnancy were included and comparing it with control groups with no supplementation or placebo administration. Data were extracted and directed using RevMan software. Fifty-nine randomized controlled trials were eligible for inclusion in the meta-analysis. Performed in MEDLINE, PubMed, Scopus, Google Scholar, and the Cochrane Library comparing omega 3 with control groups, from 1990 to 2020. THE MAIN OUTCOME MEASURES: The primary outcome measures were pregnancy-induced hypertension, preeclampsia, gestational duration, preterm birth, early preterm birth, birth weight, low birth weight, neonatal length, and head circumference. The secondary outcomes were neonatal intensive care unit, infant death, prenatal death, and cesarean section. RESULTS: In 24 comparisons (21,919 women) n-3 fatty acids played a protective role against the risk of preeclampsia (RR = 0.84, 95% CI 0.74-0.96 p = 0.008; I2 = 24%). In 46 comparisons (16,254 women) n-3 fatty acids were associated with a significantly greater duration of pregnancy (MD = 1.35, 95% CI 0.65-2.05, p = 0.0002; I2 = 59%). 27 comparisons (15,510 women) was accompanied by a significant decrease in pre-term birth less than 37 weeks (RR = 0.86, 95% CI 0.77-0.95, p = 0.005; I2 = 0%). 12 comparisons (11,774 women) was accompanied by a significant decrease in early pre-term birth less than 34 weeks (RR = 0.77, 95% CI 0.63-0.95, p = 0.01; I2 = 40%). 38 comparisons (16,505 infants) had a significant increase in birth weight (MD = 49.19, 95% CI 28.47-69.91, p < 0.00001; I2 = 100%). Finally, 14 comparisons (8,449 infants) had a borderline significance in increase in low birth weight (RR = 0.88, 95% CI 0.78-1.00, p = 0.05; I2 = 28%). CONCLUSIONS: Supplementation with omega-3 in prgnancy can prevent preeclampsia, increase gestational duration, increase birth weight and decrease the risk of low birth weight and preterm birth.

Empiric Anticoagulation Therapy in Hospitalized COVID-19 Patients: An Evaluation of Bleeding Risk Scores Performances in Predicting Bleeding Events.

Currently, there is no standardized consensus on anticoagulation (AC) among patients with coronavirus disease (COVID-19), which has an overwhelming bleeding risk. We aimed to compare the patterns of AC in COVID-19 patients and compare two validated risk scores in predicting bleeding events. A retrospective review of medical records was conducted for COVID-19 patients who received empiric anticoagulation therapy. The primary outcomes included bleeding events, survival, and mechanical ventilation needs. We applied the HAS-BLED and ORBIT bleeding risk scores to assess the predictive accuracy, using c-statistics and the receiver operating curve (ROC) method. Of the included patients (n = 921), with a mean age of 58.1 ± 13.2, 51.6% received therapeutic AC and 48.4% received a prophylactic AC dose. Significantly higher values of d-dimer and C-reactive protein (CRP) among the therapeutic AC users (p < 0.001) were noted with a significantly prolonged duration of hospital stay and mechanical ventilation (p < 0.001 and p = 0.011, respectively). The mean value of the HAS-BLED and ORBIT scores were 2.53 ± 0.93 and 2.26 ± 1.29, respectively. The difference between the two tested scores for major bleeding and clinically relevant non-major bleeding was significant (p = 0.026 and 0.036, respectively) with modest bleeding predictive performances. The therapeutic AC was associated with an increased risk of bleeding. HAS-BLED showed greater accuracy than ORBIT in bleeding risk predictability.

Epidemiological aspects of headache after different types of COVID-19 vaccines: An online survey.

BACKGROUND: Coronavirus disease 2019 (COVID-19) vaccine-related side effects are a key concern with the emergence of various types of vaccines in the market. We aimed to assess the frequency and characteristics of headache following different types of COVID-19 vaccines. METHODS: Fully vaccinated people were recruited by a convenience sample through an online survey from September 1 to December 1, 2021. Detailed analysis of headache following vaccination was investigated. Participants with a history of pre-existing headaches were telephone interviewed by a neurologist to ascertain the type of headache. RESULTS: A total of 1372 participants participated (mean age 32.9 ± 11.1). The highest frequency of headache was reported with the adenoviral vector type (302/563, 53.6%), followed by mRNA vaccines (129/269, 48%) and then the inactivated type (188/540, 34.8%). Recipients of the adenoviral vector type had a significantly longer latency between vaccination and the headache onset (median 8 h [5:12]) than recipients of the inactivated type (median 4 h [2:8], p < 0.001). Headache intensity was significantly higher with the adenoviral vector type (median 6 [5:8]) than with the inactivated type (median 5 [4:7], p < 0.001). Adenoviral vector vaccines would increase the likelihood of headache by 2.38 times more than inactivated vaccines (odds ratio [OR] 2.38, 95% confidence interval [CI] 1.83-3.04, p < 0.001). Female sex and thyroid disease were significantly associated with headache related to COVID-19 vaccines (OR 1.52, 95% CI 1.16-1.99; OR 3.97, 95% CI 1.55-10.2, respectively). CONCLUSION: Recipients of the COVID-19 vaccine should be counseled that they may experience headaches, especially after the adenoviral vector type. However, the intensity of such headache is mild to moderate and can resolve within a few days. Based on the current study design and the potential recall bias, these results may not be generalizable and should be preliminary.

Effect of using acoustic flo-tone training device and its smartphone application on enhancing inhalation technique from metered-dose inhaler with spacer in asthmatic children.

Aim of study: This research study aims to compare between two different counseling approaches; traditional verbal counseling vs. advanced counseling (in which we used the acoustic Flo-tone training device and its smartphone application combined with traditional verbal counseling) to determine the most beneficial counseling approach for asthmatic children who use metered-dose inhaler (MDI) with spacers concerning inhalation duration and inhalation technique mistakes. Methods: A total of 100 asthmatic children (8-18) years old were randomized into two groups (a control group, and an advanced group). Each group included 50 subjects. Every subject received 3 counseling meetings, one each month. Asthmatic children in the control group were trained on inhalation technique from MDI + spacer verbally (traditional counseling), while asthmatic children in advanced group were trained on inhalation technique from MDI + spacer verbally and by advanced counseling (whistling Flo-tone + smartphone application). At each visit mistakes in inhalation technique steps were; detected, corrected, and recorded and the inhalation duration was measured for every child in each group. Results: In both study groups, the total mean number of inhalation technique mistakes decreased significantly (p < 0.05) from visit 2, also the total mean inhalation durations in seconds showed a significant increase (p < 0.05) from visit 2. A significant (p < 0.05) reduction in the total mean number of mistakes and a significant (p < 0.05) increase in total mean inhalation durations were observed from visit 2 in advanced group compared to control group. Conclusion: Combination between traditional verbal and advanced counseling methods resulted in significant (P < 0.05) improvements in the number of inhalation technique mistakes and inhalation durations from MDI with spacer in children compared to using traditional verbal counseling alone.

Sanitizer-associated systemic side effects in the era of COVID-19: a pharmacovigilance study.

Background: The practice of proper hand sanitization became of utmost importance and one of the best protective measures during the pandemic outbreak of COVID-19. However, misuse of disinfectants can be an overwhelming issue because of increasing demands, public panic, and unawareness, which can negatively affect human health and the environment. Therefore, we aimed to determine whether the outbreak was associated with increased reports of adverse events related to hand sanitizers through the data of adverse events reported to the pharmacovigilance database of the Food and Drug Administration Adverse Event Reporting System (FAERS). FAERS database was analyzed for hand sanitizer reports including alcohol-based and alcohol-free formulations. Results: Adverse events reports associated with hand sanitizers increased significantly by 2020 with variable severity degrees, noting that most serious cases were reported with alcohol-based sanitizers. Conclusion: Based on data mining of the FAERS database, we claim that the increased reports associated with alcohol hand sanitizer use deserve attention. However, FAER's database has some limitations, such as case duplication and lack of a control group. Hence, further monitoring with more robust sources of data sources is critically needed.

Vitamins and other immune-supportive elements as cofactors for passing the COVID-19 pandemic.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is a viral disease that causes a respiratory disorder, started in December of 2019 in China. Several vitamins and trace elements could help in enhancing host immunity producing antioxidant or anti-inflammatory action. This work aimed to identify the role of different nutrition, vitamins, and trace elements on the immunity status of the infected subject and the possibility of the beneficial role of these elements in the management of COVID-19. MAIN BODY: After collecting (PubMed, scholar, OVID, Embase, Cochrane Library) and investigating published articles, testing the effect of these elements on viral infection, it was found that most of these elements have a significant role during viral infection through a different mechanism, like antioxidant, anti-inflammatory, and immunomodulation. Nutritional interventions in COVID-19 infections are very important currently, and it was reported that vitamin C and D reduce the risk of acute respiratory infections. In addition, low vitamin A diets compromise the effectiveness of inactivated bovine coronavirus vaccines. Administration of N-acetyl cysteine showed a beneficial inhibitory effect in viral infections and enhanced glutathione production. The deficiency of selenium on COVID-19 subjects has a significant impact on the clinical outcome of the subjects. In addition, supplementation with vitamins proved to enhance immune response during viral infection. Vitamins and trace elements not only showed a beneficial effect but also Omega 3 fatty acids showed an immunomodulating effect during infections. SHORT CONCLUSIONS: Assessment of levels for these trace elements at the baseline and providing supplementation containing different vitamins and elements could result in better control and clinical outcomes in the case of COVID-19.

The Effect of Adding a Training Device and Smartphone Application to Traditional Verbal Counseling in Asthmatic Children.

INTRODUCTION: New training devices have been introduced to help in inhaler counseling by addressing the inspiratory flow through the metered-dose inhaler (MDI), which is the most important problem of the MDI inhalation technique. This study aims to compare the effects of MDI traditional verbal counseling and advanced counseling using training devices with a smartphone application in pediatric asthmatic patients. METHODS: A total of 201 pediatric asthmatic subjects (8-18 years) were divided into two groups: a verbal counseling group, who received only MDI verbal counseling training (n = 101), and an advanced counseling group who received counseling using a training device (Flo-Tone with Trainhaler smartphone application) in addition to the traditional MDI verbal counseling (n = 100). Every patient in the two groups attended three counseling visits, 1 month apart. At each visit, pulmonary functions [peak expiratory flow (PEF), forced expiratory volume in 1 s (FEV1) as % of predicted] were measured. Also, patients were asked to perform their normal inhalation technique using their MDI, and mistakes were detected and recorded by the investigator. Then, patients were trained on the correct steps of the MDI inhalation technique using either verbal counseling or advanced counseling depending on their study group. In the advanced group, the Flo-Tone was connected to the mouthpiece of the MDI to blow a whistle while the patient inhaled from the MDI. That whistle was detected by the Trainhaler smartphone application and the duration of inhalation determined by the application was recorded. RESULTS: Both groups showed a gradual significant decrease (p < 0.05) in the total mean number of MDI inhalation technique mistakes from the second visit of counseling, and the improvement continued in the third visit, with a lower number of mistakes in the advanced group especially in inhaling at a slow rate until the lungs are a full step. Also, the advanced counseling group showed a gradual significant increase (p < 0.05) in lung function (PEF and FEV1% of predicted) from the second visit of counseling, particularly (FEV1% predicted) results which showed a greater and more rapid overall improvement in the advanced group compared to the limited overall improvements that occurred in the control group, while significant improvement (p < 0.05) of lung function was obtained at the third visit in the verbal counseling group. In the advanced group, the number of seconds measured by the smartphone application, which represents the duration of inhalation, increased significantly (p < 0.05) in the second and third visits. CONCLUSIONS: The addition of training devices and smartphone applications to traditional verbal counseling of MDI inhalation technique in asthmatic children resulted in significant improvements in lung function (especially in FEV1% of predicted results), and duration of inhalation, and progressive decreases in the average number of MDI inhalation techniques errors compared to the verbal counseling group.

Role of repeating quarantine instructions and healthy practices on COVID-19 patients and contacted persons to raise their awareness and adherence to quarantine instructions.

OBJECTIVE: This study aimed to develop a model evaluating the role of repeating quarantine instructions and healthy practices among COVID-19 patients and contact persons at-home quarantine and to evaluate the instructions' adequacy in decreasing the rate of disease spread with better clinical outcomes. METHODS: A structured questionnaire was distributed to COVID-19 patients (mild and moderate cases isolated at home) and contacting persons during May and June 2020. Data were collected using a structured online survey collected every five days for three times from each participant. The questionnaire was divided into three sections, consisting of 35 questions for a total possible score of 0 to 35. RESULTS: A total of 150 valid participant's responses out of 304 participants were obtained. Among the150 total participants, 88 were infected with COVID-19, and 62 were contacting with COVID-19 patients. The improvement in the score of awareness and adherence to instructions for the infected patients and their contacts was significantly high in the third questionnaire than in the second and the first questionnaire. The people who live in cities followed the instructions provided at the home quarantine better than those who live in the country. The city patients improved in symptoms better than the country patients. Also, patients followed the instructions better than their contacts. City females adhered to the instructions better than city males. Young people had high awareness score than older people. City people are committed to taking both immune boosters supplements as prophylaxis or prescribed medications on time for treatment more than country people. CONCLUSION: This study offers useful insights into factors associated with the role of repeating quarantine instructions and healthy practices to overcome the COVID-19 pandemic. So, repeating the instructions is important to increase adherence to the instructions, decrease the rate of disease progression and decrease the spread of the infection.

Effect of functional principle, delivery technique, and connection used on aerosol delivery from different nebulizers: An in-vitro study.

OBJECTIVE: Nebulizers can be divided according to their functional principle into jet, ultrasonic and vibrating mesh nebulizers with intermittent or continuous aerosol delivery and may be used with many different adapters and connections and all can influence their efficiency. The aim of the present work was to evaluate the effect functional principle, delivery technique, and connection used on aerosol delivered from four different nebulizers. METHODS: Four nebulizers were used in the study; three of them were jet nebulizers (JNs; AeroEclipse, NebuTech, En ful Kit) and one of them was Aerogen Solo vibrating mesh nebulizers (VMN). AeroEclipse and NebuTech are intermittent output nebulizers, while the rest are continuous output nebulizers. Aerogen Solo was used with either a standard T-piece or Aerogen Ultra holding chamber, and En ful Kit was used with a standard T-piece or Circulaire II holding chamber. 2 ml of salbutamol was nebulized to determine the total emitted dose (TED) and aerodynamic droplet characteristics of the emitted aerosol from the 6 different sets (4 nebulizers with T-piece and 2 holding chambers). RESULTS: The mean ± SD TED from VMN was significantly higher than all the JNs (p < 0.05). Aerogen Ultra with VMN did not show a significant effect on TED compare to T-piece, but it significantly increased (p < 0.05) fine particle dose (FPD; 3091.5 ± 189.4 µg) and fine particle fraction (FPF; 72.7 ± 3.6%). However, the Circulaire II with En ful Kit had significantly higher TED, FPD, and FPF compared to T-piece (p < 0.05). Intermittent JNs (AeroEclipse and NebuTech) had significantly higher TED (p < 0.05) compared to the continuous JNs (En ful Kit) with no significant effect on the other parameters studied. AeroEclipse had the highest MMAD and Aerogen Solo Ultra has the lowest in MMAD. CONCLUSIONS: The functional principle, delivery technique, and connection used had a significant effect on aerosol delivered from nebulizers. VMNs are significantly better than JNs. Intermittent delivery has significantly better TED than continuous delivery. Holding chamber with both VMNs and JNs improved aerosol delivery compared to standard T-piece.

Impact of different nebulisers' connections on aerosol therapy.

BACKGROUND: Aerosol therapy has the advantage of a higher safety because of the local deposition of inhaled medication to the lung; however, the main drawback is the low and variable amount of delivered drug to patients. Hence, this study aimed to investigate the effect of different accessory connections on aerosol delivery from different nebulisers. METHOD: This study consisted of 3 main models: in vitro, in vivo and ex vivo models. In vitro model, 6 nebulisers (3 Jet (Dolphin (2030 2001), Philips (SideStream) and Tylenol (TL009002)) and 3 vibrating mesh nebulisers (VMNs) (Aerogen Pro, Solo, an Nivo)) were charged with 5 mg/2 mL salbutamol and connected to 2 different connections (T-piece and Circulaire II Hybrid) with an inhalation filter attached to a breathing simulator. Inhaled amounts of drug (inhalation filter) and that remained inside nebuliser were measured. Concerning ex vivo and in vivo models, 24 subjects were involved in the study and they received 5 mg/2 mL salbutamol from 1 Jet nebuliser and 1 VMNs using both connections. Two urine samples were collected post 30 minutes and pooled 24 hours urine collection. For the ex vivo model, inhaled amounts of salbutamol were collected on filters placed between the subjects and the nebuliser. RESULTS: Inhaled amounts of salbutamol expressed by the amount of drug detected on inhalation filters (for both in vitro and ex vivo) were significantly higher from both Jet and VMNs connected to the Circulaire II Hybrid connection than that released from nebulisers connected to T-piece. VMNs delivered a higher amount compared with jet nebulisers. The amount released from jet nebulizers were variables, unlike VMNs. Regarding in vivo results, amounts of drug detected in 30 minutes urine samples were consistent with in vitro and ex vivo models reflecting higher and significant amounts of drug delivered to the patient's lung for Circulaire II Hybrid connection compared with T-piece regarding both nebulisers. CONCLUSION: Using a valved chamber with jet and VMNs significantly improved the inhaled amount of the emitted aerosol. VMNs were more effective than jet nebulisers with both connections.

Advanced counselling using training device and smartphone application on inhalation technique from metered-dose inhaler with spacer equipped with different interfaces in asthmatic children.

BACKGROUND: Spacers are equipped with either facemask or mouthpiece as an interface through which patient inhale their dose. The present study aimed to evaluate the effect of advanced counselling using training devices and smartphone applications on inhalation techniques from the metered-dose inhaler (MDI) with a spacer equipped with different interfaces. METHODS: 100 paediatric asthmatic children (8-18 years) were divided into two groups. Group one was a spacer with a mouthpiece (n = 50) and group two was a spacer with a facemask group (n = 50). Both groups had three visits one month apart. At each visit, patients were asked to show the investigator their inhalation technique using MDI with spacer, and mistakes were recorded and then patients were trained on the proper inhalation technique of using MDI with a spacer. In the spacer with mouthpiece group, Flo-Tone was attached to the mouthpiece to allow the Trainhaler smartphone application to detect the duration of inhalation. In the spacer with facemask group, there was no need to use the Flo-Tone training device since the facemask was equipped with a built-in whistle detected by the Trainhaler smartphone application. RESULTS: The total number of mistakes in the inhalation technique decreased significantly (P < .05) in visits 2 and 3 for both groups. Duration of inhalation increased significantly (P < .05) in the mouthpiece group at visit 2 and in the facemask group at visit 3. Achieving 5 seconds of slow deep inhalation, breath-holding for 5 seconds after inhalation and the tight fit of facemask represented the major obstacles in most children especially the youngest subjects. Breath out as far as comfortable had the highest number of mistakes in the first visit in both groups. CONCLUSION: The Flo-Tone with its positive reinforcement whistle and the Trainhaler smartphone application significantly improved the inhalation technique by decreasing the total number of mistakes especially in important steps eg, shaking MDI, maintaining slow inhalation rate, breath-holding after inhalation and appropriate facemask fitting. Also, they increased the duration of inhalation of asthmatic children from MDI with a spacer. Both spacer interfaces are easy to handle once taught well.

Effect of verbal counselling on metred-dose inhaler proper use and lung function test amongst asthmatic patients: A meta-analysis.

INTRODUCTION: The main cause of poor asthma control is mostly related to the inability of the asthmatic subjects to use their metred-dose inhaler (pMDI) correctly. The present study aimed to evaluate the role of contentious pMDI verbal-counselling on the pMDI inhalation technique and pulmonary functions of asthmatics. METHODS: Through a systematic literature search up to December 2020, 10 studies with 1937 asthmatic subjects, who had at least two pMDI inhalation technique verbal counselling sessions (visits), were identified reporting relationships between contentious pMDI verbal counselling, and the number of inhalation technique mistakes and lung functions score. Mean difference (MD) with 95% confidence intervals (CIs) was calculated comparing counselling visits results using the continuous method with a random effect model. RESULTS: Visit 1 had a significantly higher mean number of mistakes compared with visit 2 (MD, 19.98; 95% CI, 11.54-28.41, P < .001); Also, visit 2 had a significantly higher mean number of mistakes compared with visit 3 (MD, 12.17; 95% CI, 9.31-15.02, P < .001). The extent of improvement in the inhalation technique was higher between visits 1 and 2 compared with that between visits 2 and 3. The impact of continuous verbal counselling was also observed on the forced expiratory volume in one second as percentage of vital capacity [(MD, -5.56; 95% CI, -6.50 to -4.61, P < .001) between visits 1 and 2 and (MD, -6.40; 95% CI, -7.71 to -5.10, P < .001) between visits 2 and 3] and the peak expiratory flow rate [(MD, -11.47; 95% CI, -18.73 to -4.22, P < .001) between visits 1 and 2 and (MD, -16.53; 95% CI, -25.80 to -7.26, P < .001) between visits 2 and 3]. The extent of improvement in lung functions was similar between visits 1 and 2 and visits 2 and 3. CONCLUSION: Based on this meta-analysis, Continuous pMDI verbal counselling, at every possible opportunity, is a must since lung functions and pMDI inhalation technique improvements were observed with continuous pMDI verbal counselling.

Coffee and type 2 diabetes risk: Is the association mediated by adiponectin, leptin, c-reactive protein or Interleukin-6? A systematic review and meta-analysis.

AIM: Coffee and diabetes risk association has been demonstrated in numerous studies; however, the exact mechanism has not been clarified yet. The present meta-analysis was conducted to cover the current knowledge regarding the effect of coffee on Type 2 Diabetes (T2D), in addition to the evaluation of adiponectin, leptin, C-reactive protein (CRP) and Interleukin-6 (IL-6) levels among coffee consumers as relatively possible mediators of this effect. METHOD: A comprehensive search of the literature was carried out using search engines up to March 2020. The effect sizes were investigated using the standardised mean difference (SMD) and odds ratios (OR) or relative risk (RR) with its 95% confidence interval (CI). A total of 69 cross-sectional and cohort studies were included and divided as follows: 31 articles for T2D risk, 15 studies for adiponectin, 6 studies for leptin, 12 studies for CRP and 5 studies for IL-6. RESULTS: Overall, coffee consumption was inversely associated with T2D risk with an estimated pooled RR of 0.73 (95% confidence interval [0.68, 0.80] for the highest vs lowest coffee consumption categories. The combined SMD between the different coffee intake categories, showed that coffee consumption was associated with higher adiponectin levels (P = .002), and lower level of leptin (P = .04) and CRP (P = .2), with apparently no change in IL-6 levels (P = .91). CONCLUSION: The present meta-analysis showed strong epidemiological evidence that coffee consumption is inversely associated with the risk of T2D. Also, adiponectin, leptin concentrations appeared to be potential mediators of the coffee effect on diabetes, while IL-6 levels did not.

COVID-19; current situation and recommended interventions.

BACKGROUND: The new coronavirus (SARS-COV-2) that emerged at the end of 2019 was stated in China and infected millions of people around the world, with the highest spread rate amongst humans compared with other coronaviruses. This paper aimed to review and analyse the published studies about COVID-19 diagnosis, prevention, and treatment. METHOD: The reviewed studies were clinical trials, in-vivo, in-vitro, guidelines, reports from the world health organization (WHO), and the centre for disease control and prevention (CDC) in addition to systemic reviews. All data extracted and analysed to stand on the latest updates and recommendations for fighting this severe attack of COVID-19. RESULTS: Most important antiviral therapy of COVID-19 clinical trials is still running without clear results, but a few trials have indicated the role of numerous drugs in the treatment of COVID-19. Specific recommendations for aerosol therapy should be followed for the management of COVID-19. CONCLUSION: Nature of COVID-19 is still not very clear, however, management of the condition is similar to the previous attacks of coronaviruses.

Antibiotic resistance and extended-spectrum ß-lactamase in Escherichia coli isolates from imported 1-day-old chicks, ducklings, and turkey poults.

AIM: Antimicrobial resistance is a global health threat. This study investigated the prevalence of Escherichia coli in imported 1-day-old chicks, ducklings, and turkey poults. MATERIALS AND METHODS: The liver, heart, lungs, and yolk sacs of 148 imported batches of 1-day-old flocks (chicks, 45; ducklings, 63; and turkey poults, 40) were bacteriologically examined for the presence of E. coli. RESULTS: We isolated 38 E. coli strains from 13.5%, 6.7%, and 5.4% of imported batches of 1-day-old chicks, ducklings, and turkey poults, respectively. They were serotyped as O91, O125, O145, O78, O44, O36, O169, O124, O15, O26, and untyped in the imported chicks; O91, O119, O145, O15, O169, and untyped in the imported ducklings; and O78, O28, O29, O168, O125, O158, and O115 in the imported turkey poults. The E. coli isolates were investigated for antibiotic resistance against 16 antibiotics using the disk diffusion method and were found resistant to cefotaxime (60.5%), nalidixic acid (44.7%), tetracycline (44.7%), and trimethoprim-sulfamethoxazole (42.1%). The distribution of extended-spectrum ß-lactamase (ESBL) and ampC ß-lactamase genes was bla TEM (52.6%), bla SHV (28.9%), bla CTX-M (39.5%), bla OXA-1 (13.1%), and ampC (28.9%). CONCLUSION: Imported 1-day-old poultry flocks may be a potential source for the dissemination of antibiotic-resistant E. coli and the ESBL genes in poultry production.

Bacillus Calmette-Guérin vaccine, antimalarial, age and gender relation to COVID-19 spread and mortality.

COVID-19 is affecting different countries all over the world with great variation in infection rate and death ratio. Some reports suggested a relation between the Bacillus Calmette-Guérin (BCG) vaccine and the malaria treatment to the prevention of SARS-CoV-2 infection. Some reports related infant's lower susceptibility to the COVID-19. Some other reports a higher risk in males compared to females in such COVID-19 pandemic. Also, some other reports claimed the possible use of chloroquine and hydroxychloroquine as prophylactic in such a pandemic. The present commentary is to discuss the possible relation between those factors and SARS-CoV-2 infection.
