Background The impact of the COVID-19 pandemic on the population’s mental health is vital for informing public health policy and decision-making.However,information on mental health-related healthcare service utilisation trends beyond the first year of the pandemic is limited.Aims We examined mental health-related healthcare service utilisation patterns and psychotropic drug dispensations in British Columbia,Canada,during the COVID-19 pandemic compared with the prepandemic period.Methods We conducted a retrospective population-based secondary analysis using administrative health data to capture outpatient physician visits,emergency department visits,hospital admissions and psychotropic drug dispensations.We examined time trends of mental health-related healthcare service utilisation and psychotropic drug dispensations between January to December 2019(prepandemic period)and January 2020 to December 2021(pandemic period).In addition,we calculated age-standardised rates and rate ratios to compare mental health-related healthcare service utilisation before and during the first two years of the COVID-19 pandemic,stratified by year,sex,age and condition.Results By late 2020,except for emergency department visits,utilisation of healthcare services recovered to prepandemic levels.Between 2019 and 2021,the monthly average rate for overall mental health-related outpatient physician visits,emergency department visits and psychotropic drug dispensations increased significantly by 24%,5%and 8%,respectively.Notable and statistically significant increases were observed among 10–14 year-olds(44%in outpatient physician visits,30%in emergency department visits,55%in hospital admissions and 35%in psychotropic drug dispensations)and 15–19 year-olds(45%in outpatient physician visits,14%in emergency department visits,18%in hospital admissions and 34%in psychotropic drug dispensations).Additionally,these increases were more prominent among females than males,with some variation for specific mental health-related conditions.Conclusions

We explored the potential use of combining wavelength-dispersive X-ray spectroscopy(WDX) and micromorphology of thin sections to identify minerals in peat soils. Peat soil minerals from three peats and swamps across Golestan Province in northern Iran were first characterized by micromorphological studies. soils were composed mainly of quartz, muscovite, biotite, pyroxene,sericitized Fe-nodules, and iron-rich garnet. In addition,micromorphological results indicated that Galougah Coastal swamp sections contained some inorganic residue with biological origin including oyster and limpet, which may be related to the swamp's location near Gorgan Gulf.In order to determine mineralogical properties of samples,twelve unknown grains were chosen for elemental concentration map studies. Quartz, garnet, ilmenite, calcite,and pyroxene in suteh samples; epidote and Fe-nodule in Ghaleh-Ghafeh Peat swamp; and barite, phyllosilicates,and calcite in Galougah were identified by WDX mapping of si, Al, Fe, Ca, Mg, C, Ba, s, and Ti. Composition of the oysters' body was also analyzed by WDX for si, Ca, Fe,and C. The results indicated that most of the minerals in all sections likely formed through weathering, inheriting their composition from the parent rock. This research suggests that merging micromorphology and sEM/WDX image techniques can be useful in confirming the presence of mineral particles in soil science.

BACKGROUND Despite the increased use of total pancreatectomy with islet autotransplantation(TPIAT),systematic evidence of its outcomes remains limited.AIM To evaluate the outcomes of TPIAT.METHODs We searched PubMed,EMBAsE,and Cochrane databases from inception through March 2019 for studies on TPIAT outcomes.Data were extracted and analyzed using comprehensive meta-analysis software.The random-effects model was used for all variables.Heterogeneity was assessed using the I2 measure and Cochrane Q-statistic.Publication bias was assessed using Egger’s test.REsULTs Twenty-one studies published between 1980 and 2017 examining 1011 patients were included.Eighteen studies were of adults,while three studied pediatric populations.Narcotic independence was achieved in 53.5%[95% Confidence Interval(CI):45-62,Ps compared to 51.9%(95%CI:17-85,Psulinindependence post-procedure was achieved in 31.8%(95%CI:26-38,Ps with considerable heterogeneity compared to 47.7%(95%CI:20-77,Pst-surgery was reported in four studies with a pooled value of 6.76%(P=0.27).Neither stratification by age of the studied population nor metaregression analysis considering both the study publication date and the islet-cell-equivalent/kg weight explained the marked heterogeneity between studies.CONCLUsION These results indicate acceptable success for TPIAT.Future studies should evaluate the discussed measures before and after surgery for comparison.

Edge devices in Internet of Things(IoT)applications can form peers to communicate in peer-to-peer(P2P)networks over P2P protocols.Using P2P networks ensures scalability and removes the need for centralized management.However,due to the open nature of P2P networks,they often suffer from the existence of malicious peers,especially malicious peers that unite in groups to raise each other’s ratings.This compromises users’safety and makes them lose their confidence about the files or services they are receiving.To address these challenges,we propose a neural networkbased algorithm,which uses the advantages of a machine learning algorithm to identify whether or not a peer is malicious.In this paper,a neural network(NN)was chosen as the machine learning algorithm due to its efficiency in classification.The experiments showed that the NNTrust algorithm is more effective and has a higher potential of reducing the number of invalid files and increasing success rates than other well-known trust management systems.

Objective: Observe and correlate the cervical length by ultrasound and likelihood of cervical incompetence and premature delivery in multiple gestations. Materials and Methods: Retrospective study in multiple pregnancy (twin, triplet, quadruplet) delivered between 2002-2003, in King Faisal specialist Hospital and Research Centre, Riyadh, saudi Arabia. A total of 68 multiple pregnancies underwent routine ultrasound for fetal assessment between 16 - 32 weeks when the cervix was observed. The sonographic measurements included cervix > 2.5 cm and sound was divided in five groups by gestational age from 18 - 20 weeks, 21 - 24 weeks, 25 - 26 weeks, 29 - 32 weeks and >32 weeks. The gestational age at delivery was our outcome parameter. The data was analyzed statistically using Fisher’s exact test and P-value below 0.05 was considered significant. Results: Endovaginal ultrasongoraphic cervical measurement in multiple pregnancies predicted increased preterm delivery risk regardless of maternal age, previous history of preterm deliveries or presence of vaginal infection. It was found that spontaneous preterm labor s is a relatively rate outcome with cervix > 25 mm;this majority reached > 32 weeks while the patient who had cervix sound assessment will have preterm labor. The finding in ultrasound justifies the results of higher aggressive management inpatient with cervix Conclusion: Cervical assessment during routine ultrasound in multiple gestations seems to be useful for prediction of preterm delivery and counseling the patient without risk factors regarding cervical cerclage. Because of restricted number of patients, we suggest further study with bigger sample and prospective trial for valued conclusions.

Trust has become an increasingly important issue given society’s growing reliance on electronic transactions.Peer-to-peer(P2P)networks are among the main electronic transaction environments affected by trust issues due to the freedom and anonymity of peers(users)and the inherent openness of these networks.A malicious peer can easily join a P2P network and abuse its peers and resources,resulting in a large-scale failure that might shut down the entire network.Therefore,a plethora of researchers have proposed trust management systems to mitigate the impact of the problem.However,due to the problem’s scale and complexity,more research is necessary.The algorithm proposed here,HierarchTrust,attempts to create a more reliable environment in which the selection of a peer provider of a file or other resource is based on several trust values represented in hierarchical form.The values at the top of the hierarchical form are more trusted than those at the lower end of the hierarchy.Trust,in HierarchTrust,is generally calculated based on the standard deviation.Evaluation via simulation showed that HierarchTrust produced a better success rate than the well-established EigenTrust algorithm.
