Strategies to cope claustrophobia during magnetic resonance imaging examination

Background: Claustrophobia associated with MRI scan is a well-recognized problem all over the world. The unpleasant psychological experience during MRI can lead to premature cancellation of the study resulting in non-interpretable data. In addition, performing future studies on the claustrophobic patient may not be possible leading to non-utilization of an important diagnostic modality. This study was conducted with the aim to determine a cheap and short intervention which can be applicable to small radiology set up as well.Methods: A prospective study was conducted at a tertiary care hospital from October 2016 to December 2016. Accompanying someone was the first strategy used to coped MR imaging claustrophobia followed by placebo (multivitamin), listening Quran and closed eye (blindfold). All those patients who failed to respond in these strategies were finally labeled as an unsuccessful candidate. Listening of Quran was selected as one of the tools as all the patients were Muslims in present study.Results: Among 84 claustrophobic patients, a closed eye was the most successful strategy found effective in (13) 81.2%, followed by placebo 66.7% patients, listening Quran (7) 30.4%, accompanying someone (15) 17.85% while 4% patients remained claustrophobic after application of all strategies. Significant association of accompanying someone and placebo was observed with education (p-value 0.037) and age of the patients (0.016) respectively.Conclusions: In general, placebo, being accompanied by someone and blindfold were found to be the most effective strategies to cope with MRI related claustrophobia. However, the success of these strategies is also dependent on certain factors like age, education status and socioeconomic status of the patients

Ratio of height to thyromental distance: A comparison with mallampati and upper lip bite test for predicting difficult intubation in Pakistani population

Objective: To compare the accuracy of three diagnostic tests in predicting difficult laryngoscopy using Cormack and Lehane grade as the gold standard.Methods: The cross-sectional study was conducted at the Aga Khan University Hospital, Karachi, from August 2014 to August 2015, and comprised patients who required endotracheal intubation for elective surgical procedures. The primary investigator used ratio of height to thyromental distance, upper lip bite test and the modified Mallampati test for assessing the airway correlated with laryngoscopic view based on Cormack and Lehane grading. Data was analysed using SPSS 19.Results: Of the 383 patients, 59(15.4%) were classified as difficult cases of laryngoscopy. The sensitivity, specificity, positive predictive value, negative predictive value and accuracy of ratio of height to thyromental distance were 84.7%, 90.1%, 60.9%, 97%, 89.3%; and those the corresponding values for the upper lip bite test were 83.1%, 89.2%, 58.3%, 96.7% and 88.3%. The values for the modified Mallampati test were 30.5%, 84.3%, 26.1%, 86.9% and 79.9% respectively. The area under receiver-operating characteristic curve for the first two tests was significantly more than for the modified Mallampati test (p\u3c0.01).Conclusions: RHTMD and ULBT both are acceptable alternatives for prediction of difficult laryngoscopy as a simple, single bed-side test

Transaxillary Transthoracic Approach to Upper Dorsal Spine Lesions: An Anatomical Corridor with Muscle Preservation

Objective: Conventional methods for anterior upper dorsal spine are not devoid of intra-operative complications due to anatomical constraints, a major blood vessel and vital organs. We analyzed the details of Trans- axillary approach without muscle cutting in tuberculosis, tumor, and traumatic lesions of T2 to T6 and upper limb causalgia.Materials and Methods: A prospective quasi-experimental study was conducted for 3 years included 30 patients presented with dorsal myelopathy due to D2 to D6 vertebral body involvement. Right and left sided approaches were utilized. Medical Research Council grading was used to assess neurological status.Results: Mean age was 32 ± 15 years, which included male 18.60% and female 12.40%. T4 vertebrae were commonly involved. Others were T5, T3 and T6 respectively. The majority of lesions were tuberculosis of the spine (n = 14), tumor (n = 8), trauma (n = 5) and causalgia of upper limb (n = 3). No intra-operative complications occurred, estimated blood was 80-100 ml and operative time was 120-160 minutes. Postoperative complications included pneumonia (n = 1), superficial wound infection (n = 3), death (n = 1). Serial follow up was for 2 years, Patients were discharged with improved neurological status and causalgia patients got immediate post-operative relief.Conclusions: Transaxillary approach is a unique anatomical corridor which is safe, feasible with promising results. It provides optimal decompression, reconstruction with better fixation and alignment in various pathologies of upper dorsal spine

Incidence and risk factors of delirium in surgical intensive care unit

Background: To evaluate the incidence and modifiable risk factors of delirium in surgical intensive care unit (SICU) of tertiary care hospital in a low-income and middle-income country.Methods: We conducted a single cohort observational study in patients over 18 years of age who were admitted to the SICU for \u3e24 hours in Aga Khan University Hospital from January to December 2016. Patients who had pre-existing cognitive dysfunction were excluded. Intensive Care Delirium Screening Checklist was used to assess delirium. Incidence of delirium was computed, and univariate and multivariable analyses were performed to observe the relationship between outcome and associated factors.Results: The average patient age was 43.29±17.38 and body mass index was 26.25±3.57 kg/m2. Delirium was observed in 19 of 87 patients with an incidence rate of 21.8%. Multivariable analysis showed chronic obstructive pulmonary disease, pain score \u3e4 and hypernatremia were strong predictors of delirium. Midazolam (adjusted OR (aOR)=7.37; 95% CI 2.04 to 26.61) and propofol exposure (aOR=7.02; 95% CI 1.92 to 25.76) were the strongest independent predictors of delirium while analgesic exposures were not statistically significant to predict delirium in multivariable analysis.Conclusion: Delirium is a significant risk factor of poor outcome in SICU. There was an independent association between pain, sedation, COPD, hypernatremia and fever in developing delirium.Level of evidence: IV

Maternal and fetal attachment before birth: Trends in pregnant women of urban Karachi

Background: Maternal-fetal attachment is a multidimensional phenomenon and product of diverse physiological, psychological, and socio-emotional factors. The prenatal period is crucial in forming this bond and further predicts postnatal attachment.Methodology: The present research was conducted using a cross-sectional survey design. Sixty-six participants filled out the survey regarding practices, perceptions, and attitudes toward maternal-fetal attachment after attending an online session on Talking to the Baby in the Womb. Results: Analysis revealed that participants talk to their baby in their tummy. Wondering when the baby starts thinking, feeling, and hearing within also aids in forming a maternal-fetal relationship. A statistically significant difference (p=0.013) was found between HCP and PW in terms of attitude towards feeding the baby and perception of a mother giving up on the baby (p=0.04).Conclusion: The following research allows us to study the differences in the practices between healthcare providers and pregnant women so that interventions can be designed accordingly

Post-operative pain management modalities employed in clinical trials for adult patients in LMIC; a systematic review

Background: Unrelieved postoperative pain afflicts millions each year in low and middle income countries (LMIC). Despite substantial advances in the study of pain, this area remains neglected. Current systematic review was designed to ascertain the types of clinical trials conducted in LMIC on postoperative pain management modalities over the last decade.Methods: A comprehensive search was performed in June 2019 on PubMed, Cochrane Library, CINAHL Plus, and Web of Science databases to identify relevant trials on the management of postoperative pain in LMIC. Out of 1450 RCTs, 108 studies were reviewed for quality evidence using structured form of critical appraisal skill program. Total of 51 clinical trials were included after applying inclusion/exclusion criteria.Results: Results are charted according to the type of surgery. Eleven trials on laparoscopic cholecystectomy used multimodal analgesia including some form of regional analgesia. Different analgesic modalities were studied in 4 trials on thoracotomy, but none used multimodal approach. In 11 trials on laparotomy, multimodal analgesia was employed along with the studied modalities. In 2 trials on hysterectomy, preemptive pregabalin or gabapentin were used for reduction in rescue analgesia. In 13 trials on breast surgical procedures and 10 on orthopaedic surgery, multimodal analgesia was used with some form of regional analgesia.Conclusion: We found that over the past 10 years, clinical trials for postoperative pain modalities have evolved in LMIC according to the current postoperative pain management guidelines i.e. multi-modal approach with some form of regional analgesia. The current review shows that clinical trials were conducted using multimodal analgesia including but not limited to some form of regional analgesia for postoperative pain in LMIC however this research snapshot (of only three countries) may not exactly reflect the clinical practices in all 47 countries.

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.

Surgical site infection after gastrointestinal surgery in high-income, middle-income, and low-income countries: a prospective, international, multicentre cohort study

Background: Surgical site infection (SSI) is one of the most common infections associated with health care, but its importance as a global health priority is not fully understood. We quantified the burden of SSI after gastrointestinal surgery in countries in all parts of the world. Methods: This international, prospective, multicentre cohort study included consecutive patients undergoing elective or emergency gastrointestinal resection within 2-week time periods at any health-care facility in any country. Countries with participating centres were stratified into high-income, middle-income, and low-income groups according to the UN's Human Development Index (HDI). Data variables from the GlobalSurg 1 study and other studies that have been found to affect the likelihood of SSI were entered into risk adjustment models. The primary outcome measure was the 30-day SSI incidence (defined by US Centers for Disease Control and Prevention criteria for superficial and deep incisional SSI). Relationships with explanatory variables were examined using Bayesian multilevel logistic regression models. This trial is registered with ClinicalTrials.gov, number NCT02662231. Findings: Between Jan 4, 2016, and July 31, 2016, 13 265 records were submitted for analysis. 12 539 patients from 343 hospitals in 66 countries were included. 7339 (58·5%) patient were from high-HDI countries (193 hospitals in 30 countries), 3918 (31·2%) patients were from middle-HDI countries (82 hospitals in 18 countries), and 1282 (10·2%) patients were from low-HDI countries (68 hospitals in 18 countries). In total, 1538 (12·3%) patients had SSI within 30 days of surgery. The incidence of SSI varied between countries with high (691 [9·4%] of 7339 patients), middle (549 [14·0%] of 3918 patients), and low (298 [23·2%] of 1282) HDI (p < 0·001). The highest SSI incidence in each HDI group was after dirty surgery (102 [17·8%] of 574 patients in high-HDI countries; 74 [31·4%] of 236 patients in middle-HDI countries; 72 [39·8%] of 181 patients in low-HDI countries). Following risk factor adjustment, patients in low-HDI countries were at greatest risk of SSI (adjusted odds ratio 1·60, 95% credible interval 1·05–2·37; p=0·030). 132 (21·6%) of 610 patients with an SSI and a microbiology culture result had an infection that was resistant to the prophylactic antibiotic used. Resistant infections were detected in 49 (16·6%) of 295 patients in high-HDI countries, in 37 (19·8%) of 187 patients in middle-HDI countries, and in 46 (35·9%) of 128 patients in low-HDI countries (p < 0·001). Interpretation: Countries with a low HDI carry a disproportionately greater burden of SSI than countries with a middle or high HDI and might have higher rates of antibiotic resistance. In view of WHO recommendations on SSI prevention that highlight the absence of high-quality interventional research, urgent, pragmatic, randomised trials based in LMICs are needed to assess measures aiming to reduce this preventable complication
