Early continuous glucose monitoring for predicting remission of type 2 diabetes 1 year after bariatric surgery

BACKGROUND

Bariatric surgery in obese subjects can result in remission of type 2 diabetes (T2D) at a distant time post-surgery. The aim of our observational prospective single-centre study was to examine glycaemic patterns in adult T2D candidates for bariatric surgery using a continuous glucose monitoring (CGM) sensor for 14 days after surgery to search for indicators predictive of T2D remission 1 year later.

METHODS

Patients underwent CGM preoperatively and for 14 days postoperatively. Thereafter, body weight and glycated haemoglobin (HbA1c) levels were monitored at 3, 6 and 12 months after surgery.

RESULTS

A total of 31 patients (mean age 47±2 years) were analyzed. After surgery, mean interstitial glucose levels fell rapidly from 157±31mg/dL preoperatively to 109±35mg/dL postoperatively (P<0.001), reaching nadir levels from day 3 after surgery. Successful bariatric surgery (loss of excess weight ≥50%) was observed in 28 (90%) patients, and diabetes remission (HbA1c≤6% with no antidiabetic treatment) 1 year after surgery was noted in 21 (68%) patients. CGM for 14 days post-surgery allowed prediction of diabetes remission 1 year after surgery: time spent above range <14% and standard deviation (SD) of glucose levels <33mg/dL were both strong predictors of T2D remission. Indeed, the association of these two criteria predicted diabetes remission with a 100% positive predictive value, 81% sensitivity and 100% specificity and, when combined with the advanced Diabetes Remission (Ad-DiaRem) score, further increased predictive accuracy.

CONCLUSION

The use of 14-day postoperative CGM recordings together with presurgical clinical scores can help to predict diabetes remission 1 year after bariatric surgery.

Lung Ultrasound in Congenital Cardiac Abnormality: ALCAPA

Anomalous origin of left coronary artery from the pulmonary artery (ALCAPA) is a life-threatening ischemic congenital cardiac disease, resulting in myocardial dysfunction and heart failure within the first year of life. The authors report the case of a 1-mo-old infant with a radiological diagnosis of pneumonia handled with point-of-care lung ultrasound (POCUS) due to the persistence of dyspnea, despite a week of antibiotic therapy. Lung ultrasound showed a non-univocal interpretation of the lesion and gave indication to the second level instrumental diagnostics that confirmed the presence of ALCAPA. There is no case of lung ultrasound aiding to the early diagnosis of ALCAPA and no indirect ecographic signs of ALCAPA that have been described in literature yet.

Lung Ultrasound Pattern in Healthy Infants During the First 6 Months of Life

OBJECTIVES

Lung ultrasound (LUS) has gained a primary role in the diagnosis and management of pleuropulmonary disorders in pediatric practice. However, normal and pathologic patterns are translated from adult studies and have never been specifically studied in children, particularly in infants. This was a prospective observational pilot study aiming to define the normal LUS pattern in healthy infants during the first 6 months of life.

METHODS

We recruited healthy neonates at 7 to 10 days of life, and these were followed until the sixth month of life (times: 7-10 days, 1 month, 3 months, and 6 months). We excluded neonates with a gestational age before 33 weeks and neonates with cardiac or lung abnormalities or diseases, immune deficiencies, metabolic or genetic conditions, and acute or chronic respiratory diseases. A LUS evaluation was performed by a single certified pediatrician. The chest wall was examined in 18 areas, addressing A-lines, short and long B-lines, pleural abnormalities, and subpleural consolidations.

RESULTS

Thirty-seven neonates were enrolled and followed until the sixth month of life, 27 (73%) of whom were born at term (≥37 weeks) and 10 (27%) of whom were born preterm (33-36 weeks). Most of the patients at 7 to 10 days showed multiple B-lines (long and short) with a progressive normalization toward a normal A pattern at 6 months (P < .00001; 95% confidence interval, 13.75-23.24). No infants showed subpleural consolidations or pleural abnormalities.

CONCLUSIONS

This study has implications for the interpretation of LUS during the first 6 months of life. Most healthy infants show a diffuse pattern of vertical artifacts (B-lines), and the LUS pattern tends to be similar to the physiologic pattern (A-lines) after the sixth month of life. The only pathologic LUS findings were pleural irregularities and effusion and subpleural consolidations, which have never been described in healthy infants.

Lung ultrasound findings in pediatric community-acquired pneumonia requiring surgical procedures: a two-center prospective study

BACKGROUND

Lung ultrasound (US) in the evaluation of suspected pediatric pneumonia is increasingly used and has a recognized role in evaluating pleural effusions, although there are no detailed studies specifically addressing its use in the pediatric population.

OBJECTIVES

To define lung US findings of severe pediatric community-acquired pneumonia that required surgical procedures during admission.

MATERIALS AND METHODS

Our prospective case-control study compared lung US findings in patients ages 1 month to 17 years admitted with community-acquired pneumonia that required surgical procedures from findings those who did not. Lung US was performed at admission and always before surgical procedures. Medical treatment, laboratory and microbiological findings, chest X-ray, computed tomography scan and surgical procedures are described.

RESULTS

One hundred twenty-one children with community-acquired pneumonia were included; of these, 23 underwent surgical intervention. Compared with the control group, children requiring a surgical procedure had a significantly higher rate of large consolidations (52.2%; 95% confidence interval [CI]: 30.6% to 73.2%), larger and complicated pleural effusions (100%; 95% CI: 85.2% to 100%), and both liquid and air bronchograms (73.9%; 95% CI: 51.6% to 89.8%).

CONCLUSION

Larger consolidations, larger and more complicated pleural effusions, and liquid and air bronchograms were associated with surgical treatment.

Chest Computed Tomography and Lung Ultrasound Findings in COVID-19 Pneumonia: A Pocket Review for Non-radiologists

COVID-19 is an infectious disease that has quickly spread worldwide, causing a pandemic. The main clinical manifestation is pneumonia. The most important test for the diagnosis is represented by RT-PCR, but, given the limited sensitivity, further radiological examinations are necessary. We reviewed the literature to highlight the typical manifestations and advantages of chest computed tomography and lung ultrasound in COVID-19 pneumonia in order to assist clinical researchers in the management of this disease.

Acetic acid disinfection as a potential adjunctive therapy for non-severe COVID-19

Purpose

SARS-CoV-2 is a new pandemic influenza caused by a coronavirus which main route of transmission is through exhaled droplets that primarily infect the nose and the nasopharynx. The aim of this paper is to evaluate the effect of acetic acid, the active component of vinegar, as a potential disinfectant agent for upper airways.

Methods

Twenty-nine patients were enrolled and divided into two groups: group 1 (14 patients) was composed of patients treated with off-label hydroxychloroquine and lopinavir/ritonavir, whereas group 2 (15 patients) was composed of patients treated with hydroxychloroquine only, combined with the inhalation of acetic acid disinfectant at a 0.34% concentration. A questionnaire-based evaluation of symptoms was performed after 15 days in both groups.

Results

It appears that the number of patients treated with acetic acid (group 2) that experienced improvement in individual symptoms was double that of the other group of patients (group 1), although numbers are too small for robust statistical analysis.

Conclusions

Considering its potential benefits and high availability, acetic acid disinfection appears to be a promising adjunctive therapy in cases of non-severe COVID-19 and deserves further investigation.

Developmental dysplasia of the hip: real world data from a retrospective analysis to evaluate the effectiveness of universal screening

AIMS

Developmental dysplasia of the hip is an important cause of disability in children and young adult and it also has a significant socio-economic impact in our society. The main objective of our study is to evaluate, in our hospital, the effectiveness of a universal ultrasound screening protocol and to assess the general knowledge about the theme of pediatricians and neonatologists.

METHODS

Retrospective study of infants born from January 2016 to April 2019, evaluated with hip ultrasound (Graf method). Risk factors assessed were female gender, breech presentation at birth, positive family history and twin birth. For the secondary objective, an anonymous and validated questionnaire was distributed to all pediatricians and neonatologists.

RESULTS

Among the 4000 hips analyzed, on ultrasound examination, 98.8% hips resulted mature or immature but appropriate for age, while 1,2% hips were pathological. Analyzing the mature or immature hips, 2,4% were positive on clinical examination and 97,6% were negative. In relation to ultrasound pathological hips, 33,3% have positive clinical examination, while 66,7% negative. From the analysis of risk factors a significant association emerged between female sex, breech presentation and family history with the ultrasound pathological findings. The results of Survey showed that inadequate training about developmental dysplasia of the hip is done during medical school.

CONCLUSIONS

A universal ultrasound screening allowed us to identify developmental dysplasia of the hip in a number of children with normal clinical examination and no risk factors. Specific training courses should be implemented regarding Developmental Dysplasia of the Hip for neonatologists and pediatricians.

Pediatrician performed point-of-care ultrasound for the detection of ingested foreign bodies: case series and review of the literature

PURPOSE

Foreign body (FB) ingestions represent a common problem in children. History and physical examination are commonly not enough to diagnose a foreign body ingestion; therefore, conventional radiography is routinely used to detect them. Point-of-care ultrasound is widely used in the emergency department for several diagnostic applications but there are few articles describing the possibility to use point-of-care ultrasound to detect ingested foreign bodies, and the necessary training to get competent in this application. The main objective of this paper is to illustrate the use of point-of-care ultrasound (POCUS) to detect ingested foreign bodies. The secondary objective is to describe a limited training, necessary for emergency pediatricians, to obtain this skill.

METHODS

This is a case series of eight pediatric patients who presented to the pediatric Emergency Department (ED), with suspected ingestion of FB, and were assessed with POCUS. Physician sonographers were two pediatricians and three residents in pediatrics working in two Italian Pediatric EDs. All sonographers participated in a 2-day POCUS workshop which included the most common pediatric POCUS applications.

RESULTS

POCUS, performed by emergency pediatricians who participated to a limited training, allowed to always identify the foreign bodies ingested.

CONCLUSIONS

We demonstrate that an appropriate and limited training allows pediatric emergency physicians to correctly identify foreign body in the esophagus or stomach. Point-of-care ultrasound in foreign body ingestion in the Emergency Department may allow to prioritize the escalation of care in children and it can contribute to reduce the time to endoscopic management when needed.

[Coercive stress in psychiatric intensive care unit: What link with insight?]

The aim of this work was to study the correlations between the coercive experience level in patients in a psychiatric intensive care unit and clinical insight. We included 40 patients without specific diagnosis criteria at the end of their hospitalization in the intensive care unit. We assessed patients with the Coercion Experience Scale (CES) to measure their coercive stress level, and the Scale to Assess Unawareness of Mental Disorder (SUMD) which measures clinical insight. A total of 42.5 % of our sample suffered from mood disorders, 50 % suffered from psychotic disorders and 7.5 % from other disorders. On the one hand, we found that patients' coercive stress level was neither correlated with the awareness of their mental disorder nor with the awareness of social consequences of their mental disorder. On the other hand, we found that coercive stress level was significantly correlated with patients' awareness of treatment efficacy and that the specific CES factor measuring coercion showed a strong trend to significantly correlate with patients' awareness of treatment efficacy. These results seem to show that education about benefits of treatment is a key point to improve patients' coercive stress in a psychiatric intensive care unit, more than an education about awareness of the mental disorder itself.

Tongue carcinoma in young adults: a review of the literature

SUMMARY

A recent reduction in the number of smoke-related tumours has been observed thanks to the diffusion of anti-tobacco campaigns carried out in the majority of developed countries. Nevertheless, as demonstrated by recent global epidemiologic studies, squamous cell carcinoma of the mobile tongue appears to be progressively increasing in incidence, particularly among young adults and especially in females. The driving mechanism responsible for such changes is still to be precisely defined. Several genetic studies have compared the mutational pattern of tongue squamous cell carcinoma in young adults to that of more elderly patients, without identifying significant differences that may help in better characterising this subgroup of subjects. Tongue squamous cell carcinomas in young adults have been historically considered as particularly aggressive clinical entities, with a high risk of loco-regional relapse, survival rates inferior to those of the general head and neck cancer group and need for a more aggressive therapy. However, considering the most recent studies, prognostic results in this patient group are heterogeneous and it is not possible to confirm this tendency. Thus, it is not justified to embrace different therapeutic approaches according to patient age. Eventually, an additional element to consider when examining young subjects affected by tongue cancer is the possibility of genetic predisposition. Alterations affecting pathways involved in DNA repair, surveillance of genetic stability or regulation of cellular growth may determine an increased likelihood of developing head and neck cancers.

[State of immunization against measles among health professionals in at-risk units of the Caen University Hospital]

BACKGROUND

France is facing a new resurgence of measles. Since November 2017, the number of cases has been increasing sharply. Immunization coverage in the general population, all ages combined, is below the threshold required for a rapid decline of the virus propagation. Regarding health professionals, the rate of immunization against this disease is insufficiently documented. In this context, the Occupational Health Service of the University Hospital of Caen has carried out an inventory of health personnel knowledge of immunization against measles in the units the most exposed to risk.

METHODS

Knowledge of immunization against measles was studied in pediatric, imaging, and pediatric and adult emergencies departments of the University Hospital of Caen, and the Hematology Institute of Lower Normandy (IHBN). The analysis included all health professionals present within these units during the study period: March and April 2018. Data collection was carried out by consulting the medical files of the occupational health unit and considering the set of responses to postal inquiries sent to staff.

RESULTS

Measured immunization status data refer to 1017 health professionals. Based on the criteria specific to the recommendations, 234 (50.6%) of the 462 professionals born before 1980 and 437 (78.7%) of the 555 professionals born in or after 1980 could be considered as immune. Of the total sample, 115 (11.3%) had positive measles serology. Among these 1017 professionals, information on the state of immunization against measles was lacking for 174 (17.1%).

CONCLUSION

The state of immunization of the nursing staff remains insufficient to prevent the occurrence of measles cases and the staff is also insufficiently informed. It is essential to have knowledge of the immunization status of this population, to organize the vaccination of non-immunized personnel within the occupational health unit, to prevent the emergence of new cases of measles and to reinforce the information regarding the importance of precautions related to airborne transmission in case of measles.

Correlation between Human Papillomavirus Status and Quantitative MR Imaging Parameters including Diffusion-Weighted Imaging and Texture Features in Oropharyngeal Carcinoma

BACKGROUND AND PURPOSE

The incidence of Oropharyngeal Squampus Cell Carcinoma (OPSCC) cases is increasing especially in the Western countries due to the spreading of human papilloma virus (HPV) infection. Radiological investigations, MRI in particular, are used in the daily clinical practice to stage OPSCC. The aim of this study was to investigate the association of quantitative MR imaging features including diffusion-weighted imaging and human papillomavirus status in oropharyngeal squamous cell carcinoma.

MATERIALS AND METHODS

We retrospectively analyzed 59 patients with untreated histologically proved T2-T4 oropharyngeal squamous cell carcinoma. Human papillomavirus status was determined by viral DNA detection on tissue samples. MR imaging protocol included T2-weighted, contrast-enhanced T1-weighted (volumetric interpolated brain examination), and DWI sequences. Parametric maps of apparent diffusion coefficient were obtained from DWI sequences. Texture analysis was performed on T2 and volumetric-interpolated brain examination sequences and on ADC maps. Differences in quantitative MR imaging features between tumors positive and negative for human papillomavirus and among subgroups of patients stratified by smoking status were tested using the nonparametric Mann-Whitney U test; the false discovery rate was controlled using the Benjamini-Hochberg correction; and a predictive model for human papillomavirus status was built using multivariable logistic regression.

RESULTS

Twenty-eight patients had human papillomavirus-positive oropharyngeal squamous cell carcinoma, while 31 patients had human papillomavirus-negative oropharyngeal squamous cell carcinoma. Tumors positive for human papillomavirus had a significantly lower mean ADC compared with those negative for it (median, 850.87 versus median, 1033.68; P < .001). Texture features had a lower discriminatory power for human papillomavirus status. Skewness on volumetric interpolated brain examination sequences was significantly higher in the subgroup of patients positive for human papillomavirus and smokers (P = .003). A predictive model based on smoking status and mean ADC yielded a sensitivity of 83.3% and specificity 92.6% in classifying human papillomavirus status.

CONCLUSIONS

ADC is significantly lower in oropharyngeal squamous cell carcinoma positive for human papillomavirus compared with oropharyngeal squamous cell carcinoma negative for it. ADC and smoking status allowed noninvasive prediction of human papillomavirus status with a good accuracy. These results should be validated and further investigated on larger prospective studies.

Is pathological complete response after a trimodality therapy, a predictive factor of long-term survival in locally-advanced esophageal cancer? Results of a retrospective monocentric study

OBJECTIVE

To evaluate long-term (5- and 10-year) survival and recurrence rates on the basis of the pathological complete response (pCR) in the specimens of patients with esophageal carcinoma, treated with trimodality therapy.

METHODS

Between 1993 and 2014, all consecutives patients with esophageal locally-advanced non-metastatic squamous cell carcinoma (SCC) or adenocarcinoma (ADC) who received trimodality therapy were reviewed. According to histopathological analysis, patients were divided in two groups with pCR and with pathological residual tumor (pRT). The primary endpoint was overall survival (OS). The secondary endpoints included the disease-free survival (DFS), the recurrence rate, and the predictive factors of overall survival and recurrence.

RESULTS

One hundred and three patients were included: 49 patients with pCR and 54 patients with pRT. The median OS was significantly longer in pCR group than in pRT group (132±22.3 vs. 25.5±4 months), with both 5- and 10-years OS rates of 75.2% vs. 29.1%, and 51.1% vs. 13.6%, respectively (P<0.001). Also, pRT, major postoperative complications (Dindo-Clavien grade>IIIb) and recurrence were the 3 independent predictive factors for worse OS.

CONCLUSIONS

Patients with locally-advanced oesophageal carcinoma, who responded to trimodality therapy with a pCR, could be achieved a 10-year survival rate of 51%.

Should the rectal defect be closed following transanal local excision of rectal tumors? A systematic review and meta-analysis

BACKGROUND

Transanal local excision (TLE) has become the treatment of choice for benign and early-stage selected malignant tumors. However, closure of the rectal wall defect remains a controversial point and the available literature still remains unclear. Our aim was to determine through a systematic review of the literature and a meta-analysis of relevant studies whether or not the wall defect following TLE of rectal tumors should be closed.

METHODS

Medline and the Cochrane Trials Register were searched for trials published up to December 2016 comparing open versus closed management of the surgical rectal defect after TLE of rectal tumors. Meta-analysis was performed using Review Manager 5.0.

RESULTS

Four studies were analyzed, yielding 489 patients (317 in the closed group and 182 in the open group). Meta-analysis showed no significant difference between the closed and open groups regarding the overall morbidity rate (OR 1.26; 95% CI 0.32-4.91; p = 0.74), postoperative local infection rate (OR 0.62; 95% CI 0.23-1.62; p = 0.33), postoperative bleeding rate (OR 0.83; 95% CI 0.29-1.77; p = 0.63), and postoperative reintervention rate (OR 2.21; 95% CI 0.52-9.47; p = 0.29).

CONCLUSIONS

This review and meta-analysis suggest that there is no difference between closure or non-closure of wall defects after TLE.

[Can we reduce the decision-to-delivery interval in case of emergency cesarean sections by optimizing the premises' architecture?]

OBJECTIVE

To study the influence of architectural premises' improvements on decision-to-delivery interval (DDI) in case of emergency cesarean sections.

METHODS

A retrospective observational Before-After study conducted in a type III maternity, first from 2004 to 2009 (Period 1, P1) then after moving our unit to new premises from 2009 to 2013 (P2). DDI, maternal and neonatal outcomes of every emergency cesarean section were studied.

RESULTS

The mean DDI of extremely urgent cesarean significantly decreased from 21.3±10.3minutes during P1 (n=294) to 14.9±7.14minutes during P2 (n=165). During P2 there was an increase in the proportion of extreme emergency cesarean sections done in less than 30minutes (85.1% versus 93.5%, P=0.003) as according to the ACOG recommendations, and also an increase of DDI of less than 15minutes (25.8% versus 61.1%, P<0.001). Also during P2 if there was a reduction of umbilical cord pHs, which were correlated to DDI, we observed a reduction of neonatal hospitalizations (42.2% versus 35.7%, P<0.001). Apgar score was correlated to umbilical cord pH and birth weight, but not to DDI.

CONCLUSION

The space optimization has allowed our level III maternity to improve the rate of extreme emergency cesarean sections performed with DDI of less than 30 and even 15minutes, according to international recommendations. These results were obtained by reducing the transfer time to the operating room. Despite a positive correlation between DDI and umbilical cord pH, there was an improvement in neonatal outcomes associated with a decrease of neonatal hospitalizations.

Intervention of the obstetrician during childbirth in a supposedly low-risk population and influence of parity

OBJECTIVE

Compare obstetrician intervention and calling rates during labour and delivery between low-risk and high-risk women and study the influence of parity on these rates.

MATERIAL AND METHODS

Descriptive retrospective study conducted on 227 patients in a university maternity unit (level 3 university hospital maternity unit) between 1st and 30th January 2014. The low- and high-risk populations were characterised according to the French National Authority for Health (HAS) and NICE guidelines. The obstetrician intervention criteria were: Caesarean section, instrumental vaginal delivery, artificial delivery/uterus examination and postpartum haemorrhage. The obstetrical team also had to call the obstetrician in case of foetal heart rate abnormalities, scalp blood pH measurement, third and/or fourth degree perineal tears, labour dystocia, or any other severe event occurring during labour or delivery.

RESULTS

In univariate analysis, the obstetrician intervention rates were respectively 44.5% and 34.4% in the high- and low-risk groups (P=0.13). The obstetrician calling rates were similar between the two groups. Using logistic regression model including parity, the obstetrician intervention rate became significantly higher in the "high-risk" group (OR 2.044, 95% CI 1.129-3.703, P=0.018). In the low-risk population, the intervention rate was significantly increased for nulliparous women compared with multiparas (47.5% versus 9.7%, P<0.001, OR=8.2, CI 95% 2.2 to 46.9).

CONCLUSION

One third of the women defined as low-risk patients appear to need an obstetrician intervention during labour and delivery, with a major influence of parity.
