ABSTRACT

The incidence of maternal hemorrhage and blood transfusion has increased over time. Causes of massive hemorrhage, defined as a transfusion greater than 10 units of erythrocytes, include abnormal placental insertion, preeclampsia, and placental abruption. Although ratio-based transfusion has been described for managing massive hemorrhage, a goal-directed approach using laboratory or point-of-care data may lead to better outcomes. Autotransfusion, which involves the collection, washing, and filtration of maternal shed blood, avoids many of the complications associated with allogeneic blood transfusion. In this review, we provide an overview of transfusion practices related to the management of obstetric hemorrhage.

ABSTRACT

AIM: To explore the magnetic resonance imaging (MRI) differences between pancreatic neuroendocrine tumour grade 3 (pNET-G3) and pancreatic neuroendocrine carcinoma grade 3 (pNEC-G3).

MATERIALS AND METHODS: Between 2009 and 2019, 31 patients underwent pNEN-G3 resection with preoperative MRI in two local hospitals in China. The 31 patients were assigned to a pNET-G3 group (n=13) or a pNEC-G3 group (n=18). The MRI findings between the groups were compared.

RESULTS: There was no statistically significant difference between the two groups in lesion size, clinical characteristics, or laboratory indexes. The lesions showed high or slightly higher signal on diffusion-weighted imaging and decreased apparent diffusion coefficient (ADC) values, which differed between the two groups (p=0.013). The difference between the groups regarding positive enhancement integral, arterial phase and portal phase signal enhancement ratio were statistically significant; however, the delayed phase signal enhancement ratio was not significantly different.

CONCLUSIONS: pNET-G3 and pNEC-G3 showed different characteristics on MRI. In particular, the ADC value and dynamic enhanced imaging could have an important role in distinguishing between the two.

ABSTRACT

STATEMENT OF PROBLEM: The accuracy of intraoral scanners is a prerequisite for the fabrication of dental restorations in computer-aided design and computer-aided manufacturing (CAD-CAM) dentistry. While the precision of intraoral scanners has been investigated in vitro, clinical data on the accuracy of intraoral scanning (IOS) are limited.

PURPOSE: The purpose of this clinical study was to determine the accuracy of intraoral scanning with different devices compared with extraoral scanning.

MATERIAL AND METHODS: An experimental appliance was fabricated for 11 participants and then scanned intraorally and extraorally with 3 different intraoral scanners and a reference scanner. Intraoral and extraoral scans were subdivided into complete-arch and short-span scans and compared with the reference scan to assess trueness. Repeated scans in each group were assessed for precision.

RESULTS: Precision and trueness were higher for extraoral scans compared with intraoral scans, except for complete-arch scans with 1 intraoral scanner. The median precision of short-span scans was higher (extraoral: 22 to 29 μm, intraoral: 23 to 43 μm) compared with complete-arch scans (extraoral: 81 to 165 μm, intraoral: 80 to 198 μm). The median trueness of short-span scans (extraoral: 28 to 40 μm, intraoral: 38 to 47 μm) was higher than that of complete-arch scans (extraoral: 118 to 581 μm, intraoral: 147 to 433 μm) for intraoral and extraoral scanning.

CONCLUSIONS: Intraoral conditions negatively influenced the accuracy of the scanning devices, which was also reduced for the complete-arch scans.

ABSTRACT

Atezolizumab is an anti-PD-L1 immune checkpoint inhibitor recommended for the treatment of locally advanced or metastatic urothelial carcinoma (mUC) after prior platinum-containing chemotherapy, regardless of PD-L1 status, among other treatment settings. We conducted a long-term follow-up to the exploratory analysis of overall survival (OS) and safety for the IMvigor211 intent-to-treat (ITT) population. Patients with mUC and disease progression during or following platinum-based chemotherapy were randomised 1:1 to receive atezolizumab 1200 mg or chemotherapy (vinflunine 320 mg/m², paclitaxel 175 mg/m², or docetaxel 75 mg/m² according to investigator choice) intravenously every 3 wk. Although the primary analysis did not demonstrate statistically significant longer OS for patients receiving atezolizumab versus chemotherapy, updated OS showed long-term durable remission. With a median of 33 mo of follow-up, the 24-mo OS rate was 23% with atezolizumab and 13% with chemotherapy. Safety findings were consistent with the primary analysis, with no new signals detected. Chemotherapy-treated patients experienced more grade 3/4 treatment-related adverse events (AEs; 43% vs 22%) and more AEs leading to treatment discontinuation (18% vs 9%). Atezolizumab-treated patients experienced more AEs of special interest (35% vs 20%), which tended to be grade 1-2. Our findings support the use of atezolizumab in platinum-treated patients with mUC regardless of PD-L1 status. PATIENT SUMMARY: We report follow-up results from a study of an immunotherapy treatment, atezolizumab, in patients with bladder cancer who had already received platinum-containing chemotherapy. This analysis compared the effectiveness of atezolizumab with chemotherapy over 2.5 years after starting treatment. The results show that patients who received atezolizumab lived longer and had manageable side effects compared with patients who received chemotherapy. This trial is registered at ClinicalTrials.gov as NCT02302807.

ABSTRACT

INTRODUCTION: Electrical burn injuries are devastating and cause not only loss of life but also severe disabilities in the form of limb loss. Increase in urbanization, industrialization and overcrowding has led to an increase in electric injuries.

MATERIAL AND METHODS: The study was prospective in nature evaluating electric burns and studied the pattern of limb loss for a duration of 18 months from October 2016 to March 2018. Parameters recorded were demographic data, clinical data regarding the electrical injuries, complications, and outcomes.

RESULTS: Male patients made up 85.3% of cases. Mean TBSA was 24.76 ± 19.18%. Mean age was 27.59 ± 13.73 years. Pediatric patients made up 17%. High voltage burns constituted 68.2 %. Electric contact burn was the most common type making up 49.5% of cases. The most common cause was occupational (38.9%). A fasciotomy was required in 22% of cases with an amputation rate of 38% (209 out of 550). There were 190 major amputations and 106 minor amputations. Overall, the right upper limb amputations were twice as common as the left. The ratio of upper limb: lower limb amputation was 4:1. Fifty patients (23.9%) required revision amputation. The age group 11 to 30 years made up 55.5% of amputations. There was no statistical difference in amputation rates between males (31.31%) and females (41.97%). In patients with TBSA less than 25% amputation rate was 47.77% as compared to patients with more than 25% TBSA, 19.47% (p<0.001). Most amputations occurred due to electric contact burns (74.16%). In the high voltage group, 46.1% underwent amputation vs low voltage group -20.6% (p<0.001). Overall mortality rate was 12.7%. Three hundred patients (55%) had low level of awareness regarding consequences of electric injury. Thirty one percent had medium level of awareness and only 14 % had high level of awareness. There was a significant correlation between education level and awareness in adult patients (p<0.001). Seventy percent of persons with occupational injuries used only footwear and no other protective equipment.

CONCLUSION: Increasing public awareness, safety measures at workplaces are measures that will help reducing electrical burns which reduce limb and life loss.

ABSTRACT

BACKGROUND: COVID-19 was declared a pandemic by the World Health Organization (WHO) on 11th March 2020. Individuals with correct understanding about the risks and severity of the disease are more likely to respond positively and practice recommended preventive measures.

OBJECTIVES: To assess the knowledge, attitudes, and practices towards COVID-19 transmission and preventive measures among residents of Nigeria.

METHODS: The study was cross-sectional and involved 469 participants from 1st July to 31st August 2020. A 36-item questionnaire with Cronbach alpha of 0.753 was adapted and administered through an online survey tool. A snowball sampling approach was employed whereby the questionnaire link was distributed through social media networks including WhatsApp©, Facebook© and Instagram©. Data was analysed using SPSS 23 and a statistical significance level of 0.05 was used. Bivariate and multivariate analysis were employed to determine factors affecting the knowledge, attitude and practices towards COVID-19 transmission and prevention.

RESULTS: The mean age of participants was 39±11.29years. Majority (54%) of the participants heard about COVID-19 through mass and social media. The study found that 71.6% of the participants had good knowledge, just 31.3% had a good attitude while 84.9% of them had good practices towards COVID-19 in Nigeria. The high rates of the knowledge and practices were driven by income, age, education and marital status.

CONCLUSIONS: Majority of the study participants showed correct knowledge and adhered to recommended practices towards COVID- 19. However, there were gaps in the understanding of the underlying realities and beliefs in certain myths about COVID-19. Hence, interventions such as jingles and posters in various languages that would serve to correct the negative perceptions and myths about COVID-19 instituted through mass media and social media are recommended.

ABSTRACT

BACKGROUND: School Health Instructions (SHI) entail the instructional aspect of school health programme, which provides a classroom opportunity for inculcating healthy habits into the school- age child.

OBJECTIVE: To assess the status of implementation of school health instruction in primary schools in Gwagwalada Area Council of the Federal Capital Territory, Nigeria.

METHODS: A cross-sectional descriptive study of 146 primary schools in the Gwagwalada Area Council of the Nigerian Federal capital was carried out to assess the implementation of SHI with respect to the contents, methods of delivery and teachers preparation for health teaching using an evaluation checklist for SHI.

RESULTS: Of 146 schools, 115(78.8%) schools attained the minimum acceptable score of 27. Of the 40 public and 106 private schools, 27(67.5%) public and 88(83.0%) private schools attained the acceptable minimum score of 27. There was a statistically significant difference between the mean scores attained cumulatively in the various components of the school health instruction by the public and private schools (t=2.721, p= 0.008). Public schools had significantly more teachers with education-related qualifications than private schools (p<0.001). Teachings on HIV/ AIDS, safety education and community health were undertaken by 95.9%, 93.2% and 95.2% schools respectively. Only 5(3.4%) schools followed the recommendation of giving health instruction at least thrice a week.

CONCLUSION: Implementation of SHI was adequate in the study area, with a better performance among the private schools.

ABSTRACT

The need for changes in the primary health care system in the Russian Federation that is based on the principles of general medical practice is without any question. But, even after more than thirty years, there is no full-fledged reform still.

THE OBJECTIVE: To assess the state of general medical practice in the Russian Federation to identify its strengths and weaknesses, and to determine further ways of its development. The tasks. To analyze the volume and pace of development of general medical practice; to identify its impact on key demographic, medical and social indices; to assess foreign experience in this field; to elaborate proposals on intensifying process of its development in the Russian Federation.

MATERIAL AND METHODS: The analytical, sociological (n=1,573) and statistical methods were applied.

THE RESULTS: Since 2007, the number of general practitioners in the Russian Federation and corresponding support of the population increased. During the same time period, population size, natality, mortality, morbidity of tuberculosis, essential hypertension and cataract had positive dynamics. The morbidity of malignant neoplasms, diabetes type II, glaucoma, coronary heart disease and cerebrovascular diseases had negative dynamics. The strong negative relationship of the population’s general practitioners support was established only in case of all-cause mortality and morbidity of lungs tuberculosis. The population was more satisfied with support of general practitioner than district physician.

DISCUSSION: The general practitioner support of the population of the Russian Federation continues to be insufficient and its role in public health management insignificant. The proposals are formulated to improve primary health care and its further development based on the principles of general medical practice on the basis of corresponding best international experiences and national specificity. Hence, in Russia, the national health care requires a set of measures targeted to strengthen the position of general medical practice system throughout ll territories.

ABSTRACT

The chronic kidney disease takes a special place among chronic non-communicable diseases because it is characterized by wide prevalence worldwide. However, its detection rate among Moscow adult population is 1%, though in the European countries this indicator is significantly higher and is made up on average to 6%. At the terminal stage of chronic kidney disease, quality of life of such patients decreases dramatically, that result in working capacity loss and disability. These patients often require expensive methods of programmed hemo- and peritoneal dialysis. The corresponding mortality is much higher as compared with total mortality. Among the frequent causes of hospitalization and mortality of such patients, complications of blood circulation system diseases are registered. The existing problem of low detection of kidney pathology in the population is the main cause of untimely treatment start. The rapid disease progression results in higher indices of premature mortality and increased costs of treatment of patients with this pathology. The timely diagnosis of disorders of carbohydrate and lipid metabolism permits to identify chronic kidney disease at an early stage and to start to carry out adequate treatment and prevention measures. The purpose of the study is to implement the technology of improving efficiency of detection of chronic kidney disease. Methods. The organizational experiment, analytical, mathematical and statistical research methods. Results of the study. The detection rate of chronic kidney disease amounted to 8%. Among the respondents with chronic kidney disease diagnosed, more than 80% had initial stages of disease (I-III). In this case, appropriate therapy and prevention can prolong kidney functioning and reduce velocity of disease progression. At the same time, 16.3% of patients at the late stage of diseases progression (stages IV-V) were identified.The detection rate for all stages of chronic kidney disease increases with age Conclusions. The level of detection of chronic kidney disease in the base territory is comparable with the indices established in the European countries. The need to improve quality of diagnostic and prevention of chronic kidney disease was proven. To improve overall prognosis and prevention of development of terminal renal failure is possible only in case of brigade approach to treatment including active interaction of cardiologist and nephrologist, endocrinologist and nephrologist or of all these three specialists. Scope of the results. The established higher detection rate of chronic kidney disease (8%), as compared to actual one (1%), permits to claim that with systematic improvement of diagnosis, the detection of chronic kidney disease will increase iteratively and population need for nephrologic medical care will significantly increase that will require increasing in resource support and revising of planned and normative indices for this type of medical care.
