Subduction, uplift and serpentinite in Cyprus: insights from seismicity
Authors: Merry Thomas , Bastow Ian , Green David , Nippress Stuart , Peach Charlie , Bell Rebecca , Pilidou Sylvana , Dimitriadis Iordanis , Ugo Freddie
Published: February 2023

Cyprus sits at the plate boundary between Anatolia in the north and Africa in the south, at a transition from oceanic subduction in the west to continental strike-slip and collision tectonics in the east. The nature of the plate boundary at Cyprus has been historically controversial and poorly understood, in part due to a lack of constraints on local seismicity. Ongoing subduction of either oceanic or continental African lithosphere is argued, with some invoking subduction of the Eratosthenes Seamount, a continental fragment to the south of Cyprus rising 2km above the sea floor, as a driver of uplift in Cyprus. At the centre and highest point of the Troodos ophiolite, which dominates the island, is the Mt Olympus mantle sequence, an outcrop of heavily serpentinised peridotite that is associated with a localised gravity low and proposed to be the top of a rising serpentinite diapir. Geophysical constraints to test these hypotheses at depth are lacking.  We analyse data from a two-year deployment of five broadband seismometers along with the existing permanent network to create a new earthquake catalogue for Cyprus. We use our catalogue to constrain the first formalised 1-D velocity model for the island, improving earthquake locations. Earthquake hypocentres clearly delineate a northward-dipping African slab beneath Cyprus at 20-60 km depth. The most seismically active part of the island is at 15-20 km depth beneath the southern edge of the ophiolite, approximately the expected depth to the plate interface; thrust faulting focal mechanisms here are consistent with ongoing subduction. Hypocentral depths suggest a topography of the slab top, with the shallowest depths in the centre of the island, coincident with the greatest uplift in the overlying plate, supporting hypotheses of uplift driven by subduction of the Eratosthenes Seamount. A lack of seismicity in a 20km-wide zone at this ‘peak’ coincides with the outcropping Mt Olympus mantle sequence, and may be associated with the deep root of the proposed serpentinite diapir. 
Overturning of mixed layer eddies in a submesoscale resolving simulation of the North Atlantic
Authors: Epke Moritz , Brüggemann Nils
Published: February 2023

Submesoscale Instabilities in the mixed layer can lead to ocean restratification and thus affect ocean-atmosphere feedbacks. In this study, a novel configuration of the ICON ocean model is applied which makes use of telescoping grid refinement such that a horizontal resolution finer than 600m is achieved over wide areas of the North Atlantic. The ability of the model to simulate mesoscale to submesoscale turbulence is validated by comparing spatial power spectra of sea surface temperature and sea surface hight with those of satellite products and a ICON simulation of 10km horizontal resolution (often referred to as "mesoscale eddy resolving").We find more realistic variability in the simulation with the refined grid compared with coarser simulation over a wide range of scales that even includes the mesoscale eddy regime. Moreover, the high-resolution permits submesoscale baroclinic and symmetric instabilities. At single fronts, we observe strong overturning re-stratifying the fronts. Overturning rates are diagnosed regarding mean characteristics of the fronts like mean horizontal and vertical density gradients and mixed layer depth. Finally, the diagnosed overturning rates are compared to recent parameterizations introduced by Stone (1971) and Fox-Kemper (2008). It turns out that both parameterizations are roughly able to capture the bulk overturning along strong fronts but have problems in non-frontal regions.
Identification of earthflow-prone slopes (solifluction) in permafrost regions by a combination of satellite-based interferometry and in-situ investigations - a case study in Yushu, Sanjiangyuan, Qinghai-Tibet Plateau
Authors: Meng Qingkai , Intrieri Emanuele , Raspini Federico , Peng Ying
Published: February 2023

The headwater regions of the Yangtze, Yellow, and Mekong rivers are called Sanjiangyuan in Qinghai-Tibet Plateau. During the last decades, glaciers and permafrost are suffering from rising temperatures and precipitation, thus exacerbating surface instability and fostering landslides consequently. We utilized satellite-based interferometric monitoring to detect instability precursors and reconstruct deformation scenarios with 106 descending Sentinel-1 SAR images acquired from February 2016 to July 2020 in Yushu, Sanjiangyuan region where a typical earthflow occurred. Considering freezing and thawing would induce a large bias from linear deformation, the newly developed model was proposed by integrating in-situ soil temperature and moisture to separate the gravity-driven displacement and seasonal deformation. Four potential landslide prone slopes were identified in a less steep and shady landform with a maximum creep speed up to 45 mm at the regional scale. For the Yushu slope case, slow creep and accelerating creep behaviors were retrieved as precursory with the displacement rate varying from 11 mm/yr to 21 mm/yr before the failure. A seasonal oscillation pattern without gravity displacement was detected at the post-failure stage. In addition, we found that complex piecewise deformation patterns can be characterized by fast uplift (with the maximum deformation up to 20 mm in less than 30 days) in the early winter, and relatively slow subsidence in summer thawing (with the maximum value estimated by 10 mm in more than 37 days). The magnitude and duration of seasonal displacement were highly correlated with the internal hydro-thermal regime, especially soil moisture. Our result highlighted that a deformation separation model is necessary for identifying potential solifluction, evaluating the deformation state, and even forecasting risk in the periglacial regions.
Sedimentary Genesis and Distribution of High Argillaceous Sandstone
Authors: Liu Xudong
Published: February 2023

Area A is located in the east of Yangjiang Sag in Zhusan Depression, Pearl River Mouth Basin. The Neogene Hanjiang Formation in this area has deposited a large number of sand, silt and mud mixed clastic sediments, with different particle sizes and complex composition. Predecessors have done some research on lithology, sedimentation and reservoir of this Formation, but the understanding of genesis and distribution of high argillaceous sandstone is not clear. In this paper, the genesis and vertical distribution of high argillaceous sandstone in Hanjiang Formation are analyzed by core, logging and analytical test data. Combined with high resolution seismic data, the density and seismic elastic parameters inversion method are used to clarify the plane distribution characteristics. The results show that high argillaceous sandstone is mainly distributed in deltaic front underwater distributary channel, interdistributary bay and distal bar. Sediment deposition rate of deltaic front underwater distributary channel is fast, low energy hydrodynamic can not be fully scoured sediment screening, resulting in high mud content. The hydrodynamic conditions of deltaic front interdistributary bay and distal bar are weak, and fine-grained and argillaceous sediments are deposited in large quantities, so the argillaceous content of sandstone is high.
A Simple Metric, Total PM10:Total Wind Power Density, to Quantify Changes in Dust Emission from Areas of Interest as a Function of Environmental Change
Authors: Gillies John , Furtak-Cole Eden , Nikolich George , Etyemezian Vic
Published: February 2023

The flux of wind-driven dust emissions from a susceptible area is determined by a complex relation between the driving force of the wind and the emissivity of the surface.  This relation is also modulated by the availability of sand-sized particles available for saltation, the roughness of the surface, and environmental conditions related to moisture, i.e., soil moisture and relative humidity.  The flux (F, µg m-2 s-1) of dust-sized particles from the surface scales non-linearly with the shear stress (τ, N m-2, or shear velocity u*, m s-1 [τ=ρu*2, where ρ is fluid density]) created by the wind flowing over the surface.  Shear stress or shear velocity are not easily measured without the use of multiple instruments to characterize the vertical gradient of wind speed; vertical flux of particles requires measurement of vertical gradient of particle concentration or application of the eddy covariance method.  Here we describe a simple but effective metric to track changes through time due to physical alteration of a surface or due to changes in the environment.  The metric is based on measuring mean hourly concentrations of particulate matter, e.g., PM10 (µg m-3) and mean hourly wind power density (WPD=0.5×ρ×A×wind speed3, W m-2), which quantifies the power in the moving air.  A is area, that we arbitrarily set at 1 m2.  These hourly values are individually summed over a period of interest (e.g., monthly) to calculate the ratio value of total PM10:total WPD.  These data can also be filtered to isolate the effect of the source area emissions on the receptor site, for example, by wind direction range.  Tracking this metric on a monthly basis across multiple years at the Oceano Dunes State Vehicular Recreation Area has allowed for the characterization of the change in dust (PM10) production due to dust control measures (i.e., hectares of dust control) being placed onto the dunes, as well as the changes to the dust emission system during a period in 2020 when the area was left relatively undisturbed due to restrictions due to COVID-19.  We suggest, and demonstrate, that this method can be broadly applied, is effective in quantifying change, and cost-effective.
Spatiotemporal Characteristics and Drivers of Groundwater Change in North China Revealed by GRACE Time-Variable Gravity
Authors: Feng Tengfei , Shen Yunzhong , Chen Qiujie , Wang Fengwei
Published: February 2023

Groundwater overdraft in North China (NC) has posed adverse threats to sustainable development due to the reduction of freshwater availability. To comprehensively clarify the groundwater change and formulate reasonable control strategies, groundwater storage anomaly (GWSA) is investigated using the high-resolution time-variable gravity field model Tongji-RegGrace2019 together with the hydrological model. The results show that GWS presents a downward trend of -0.87±0.04 cm/yr from January 2004 to December 2015 and the trend aggravates to -3.71±0.49 cm/yr from January 2014 to December 2015, which is basically consistent with those detected by monitoring well. Moreover, by analyzing the spatiotemporal characteristics of GWSA with the independent component analysis (ICA) approach, the driving factors and corresponding mechanisms of groundwater changes are determined. Among the four independent components (ICs) of GWSA, the first two ICs (IC1 and IC2) cooperatively reflect the long-term and intra-annual groundwater changes caused by water consumption of coal mining and agricultural irrigation in Shanxi province, with the correlation coefficients of -0.91 and -0.85, respectively. IC3 indicates a semi-annual groundwater signal related to agricultural irrigation water consumption in southern Hebei province, with a correlation coefficient of -0.85. Besides, IC4 suggests the effect of monsoon precipitation and evaporation in front of Taihang Mountain. Hence, multiple driving sources, including unevenly distributed precipitation, intense seasonal evaporation, and devastating coal mining, coupled with extensive agricultural irrigation, jointly restrict the GWSA rise and fall at different time nodes.
On the reliability of the Panalesis (v.0) paleogeographic maps
Authors: Vérard Christian
Published: February 2023

Palæogeography is the definition of the geography of the Earth in the geological past. However, geography depends on topography (both on land and under the sea) and the sea level which defines the coastline. Topography is a multifactorial resultant whose heart is the geodynamic context that created it (Vérard, 2019). In other words, there are no palæogeographic reconstructions if there is no plate tectonic model underlying them.The palæogeographic maps presented here are derived from the Panalesis model (preliminary version or v.0), corresponding to palæo-digital elevation models (palæo-DEM) that cover the entire Phanerozoic on a global scale associated with sea level variations from Haq et al. (1987, 2008, 2018).The results show two main facts. First, the main shortcomings of the method for converting a plate tectonic map to a palæogeographic map (Vérard et al., 2015) are relatively well understood and should be improved with new versions of the plate tectonic model (Verard, 2021) and the conversion code. Secondly, lithofacies databases (fossils and palæo-environments) on a global scale are needed to identify areas that are outside the “standard mode” defined by synthetic topographies and to understand the reasons for the discrepancies. Conversely, variations (global to regional) in lithofacies can only be understood if a quantified topographic model is proposed as a reference, which Panalesis is, to date, the only one to systematically offer. REFERENCES1.

Published: February 2023

To explore aerosol chemistry and climate change, information of the physical state of aerosol particles is essential. Herein, we measured viscosities of binary mixtures of sucrose/H2O and ammonium sulfate (AS)/H2O, and ternary mixtures of sucrose/AS/H2O with different organic-to-inorganic dry mass ratios. For sucrose droplets, the viscosity gradually enhanced from ~4 × 10-1 to > ~1 × 108 Pa‧s as the relative humidity (RH) decreased from ~81% to ~24%. This corresponds from liquid to semisolid or solid state. For AS droplets, the viscosity dramatically enhanced at ~ 50% RH upon dehydration; to be < 102 Pa‧s for RH > ~50% (liquid state), and > ~1 × 1012 Pa‧s for RH ≤ ~50% (solid state). In case of the ternary mixtures, remarkable enhancement in viscosity was observed as the inorganic ratio increased at a given RH. All particles studied in this work were observed to exist as a liquid, semi-solid or solid depending on the organic-to-inorganic dry mass ratios and RH. Moreover, the measured viscosities of the binary and ternary mixtures were compared with the calculated viscosities using the Aerosol Inorganic–Organic Mixtures Functional groups Activity Coefficients Viscosity model (AIOMFAC-VISC) predictions with the Zdanovskii–Stokes–Robinson (ZSR)-style organic–inorganic mixing model. It showed excellent model–measurement agreement. The result will be discussed.
Genesis and Distribution Prediction of High Calcareous and Low Permeability Sandstone
Authors: Zheng Wei
Published: February 2023

The Zhujiang Formation in A oilfield of Yangjiang Sag, Pearl River Mouth Basin has superior reservoir-cap assemblage and good oil accumulation conditions. However, due to the frequent drilling of high-calcareous and low-permeability sandstone, and the unclear understanding of the formation of high-calcareous and low-permeability sandstone and the distribution of sand bodies, the oil and gas exploration progress is restricted. In this paper, the formation and vertical distribution of high calcareous and low permeability sandstone are studied by using core, logging and analysis data combined with the sedimentary background in this area, and seismic inversion of reservoir is carried out by using seismic data combined with permeability, so as to realize the plane distribution prediction of high calcareous and low permeability sandstone. The results show that the Zhujiang Formation in the study area is mainly characterized by underwater river-bay microfacies, which provides abundant carbonate provenance conditions for high calcium content of sand bodies. And the sand bodies in the underwater distributary channel microfacies are closely interlaced with the calcare-rich mudstone at the top-bottom interface, moreover the migration of carbonate from mudstone to sandstone and related chemical reactions occur at the junction, which further increases the calcium content of sand bodies. Combined with the study of permeability inversion model, it is considered that the high-calcareous and low-permeability sandstones are mainly distributed in the underwater distributary channel near the provenance in the northern part of the study area.
Inception of Agri-Derivatives Market for Protecting the Farmers of Bangladesh from Price Risk: A Chattogram Perspective
Authors: Monzur Morshed Bhuiya Md. , Uddin Chowdhury Tasnim
Published: February 2023

This study aims to explore the necessity of developing agricultural commodity derivatives market in Bangladesh, a South Asian country, where fluctuation in price of essential agricultural commodities has become a regular phenomenon. No market mechanism is there by which farmers can get protection against the risk arising from price fluctuation in the country. As such, frequent loss incurred from such adverse price movement is de-motivating many of them to switch their profession. In this study data from both sources, primary and secondary, has been used. Primary data has been collected through the use of structured questionnaire and has been analyzed through descriptive statistics. The study reveals that with an opportunity of prefixing the price during the time of cultivation almost all of the respondents expect that they would not worry regarding a price decline, would be able to recover their production cost, would get their expected level of price, would be able to ensure fair price and predict the price they would get after harvesting more accurately. This implies that they desires for a market mechanism through which they would be able to get protection against the decline in price and it is the agricultural derivatives market that can fulfill their desire well. This study would help the policy makers and expect to inspire them to conduct a survey at large scale so that proper steps can be taken for the successful inception of agricultural derivatives market in the country that would benefit the farmers of the country.

Published: February 2023

Success in extending life expectancy should be viewed wisely as a manifestation of the success of human resource development in the present. However, it cannot be denied that with the increasing number of elderly people, this has the potential to cause various problems. One of them is related to the reduced level of population productivity. The elderly group often becomes unproductive because of the decline in their physical and mental conditions. This study aims to analyze the relationship between family support and successful aging in the elderly in Panulisan Dayeuhluhur Village. The research design used is correlational or relationship research with a cross sectional approach. The number of samples in this study were 52 of the 1073 elderly population in Panulisan Barat Village with a randomized proportional sampling technique. From the results of the Colmogorov-Smirnov test, it is known that there is a significant relationship between family support and successful aging in the elderly, with a p value of 0.000 which is smaller than an alpha of 0.05. Suggestions for nursing practitioners from the results of this study can be used as input to bring active efforts to health workers, especially gerontic nurses in the community in giving a social impression to the elderly, so that it is expected to produce better living conditions for the elderly. Further research is expected to dig deeper into the dimensions of family support in an effort to improve Successful Aging in the elderly with a deeper analysis of each dimension

Challenges for the insurance industry in the future
Authors: Nicholson Jack E.
Published: February 2023

The author discusses several development and trends related to insurance that were presented in May 2019 at the Florida State University Future of Insurance Forum, including the role of technology and catastrophe exposures. Advances in technology are changing the insurance industry, and its future workforce will require new skill sets and greater flexibility. The growth of exposures in coastal states, flood zones and earthquake-prone areas will necessitate updated tools for state insurance regulators and rating agencies to monitor financial solvency. More needs to be understood about climate change, the climate models and whether man-made climate change can be linked as a cause of future disasters. Although the loss adjustment processes of insurers have improved over time, the settlement of catastrophic claims entails continuing problems. Insurance linked security (ILS) products are serving to provide additional capital and to stabilize the rapidly growing reinsurance market.

CLINICAL EFFECTIVENESS OF TITANIUM CAD/CAM RETAINERS FROM A BIOCHEMICAL POINT OF VIEW
Authors:   Department of Orthodontics, Faculty of Dental Medicine, Medical University, Sofia, Bulgaria., Petrunov Vladimir
Published: February 2023

Following the integration of fixed retainers into the clinical practice, an increasing number of orthodontists prefer this retention method. Further to the proven advantages of those retainers, however, there are some deficiencies, which, if not taken into consideration, might compromise the good treatment result. CAD-CAM methods employ a different approach in design, materials and method of fabrication, and clinical procedures with respect to fixation. This allows for the avoidance of a large part of the deficiencies of the fixed retainers that are made manually. Aim: Our aim is to demonstrate the clinical effectiveness of titanium CAD/CAM fixed retainers. Materials and methods: Swing (DOF) Laboratory scanner was used to scan the models. Retainers were designed through Exocad Matera (Exocad GmbH) software. Retainers were fabricated of titanium Ti G5 (SILADENT Dr Böhme & Schöps GmbH) discs, machined with CORiTEC 650i (Imes-icore GmbH) 5-axis dental milling machine. Results: The outcome is a retainer, which is excellently fitting to the dental surface, absolutely passive, resistant to plastic deformation, fracture-proof and with an extremely easy clinical fixing procedure. Conclusion: CAD/CAM methods employ an innovative approach, providing a different manufacturing technology and the use of various materials for the purposes of fixed retention. These methods eliminate a significant part of the deficiencies of the conventional manually bent retainers.

Introduction: Apparently, Complementary and Alternative Medicine (CAM) is a recognized medical practice that precisely makes use of multiple treatment therapies and techniques in the prevention and management of variety of human disorders. Having a glance at the future, health science students belonging to different universities would take the leadin hospitals and health centers thus this study aims to analyze the level of knowledge, attitude and perception of them towards CAM in Nepal, also aims at awaking students about CAM therapies, related side effects, risks and possible complications.

Methods: A cross sectional descriptive study was organized by enlisting 385 undergraduate students, pharmacy(107) and non-pharmacy (278) which encompasses demographic characteristics, source of information, knowledge, attitudes and perception towards CAM.

Results: Report indicated that predominance of students had good knowledge regarding homeopathy (Pharmacy:81.3%, NP:71.9%, P-value:0.044), herbalmedicine (Pharmacy:62.5%,NP:56.5%, P-value:0.008, acupuncture (Pharmacy:72.9%, Non-Pharmacy:62.2%, P-value:0.073), gingko (Pharmacy:52.3%, Non-Pharmacy:40.6%), ginseng (Pharmacy:52.3, Non-Pharmacy:34.9%, P-value:0.001). In spite employing non reliable origin of CAM information and their mindset that CAM is proceeded by quacks, the preponderance of students had positive attitudes and perception regarding CAM management. However, few non pharmacy students believe that CAM should be adapted by legislation (Pharmacy: 78.5%, Non-Pharmacy: 66.2%, P-value: 0.032), only few believe that CAM is a convenient appendage via traditional medication (Pharmacy: 84.1%, Non-Pharmacy: 70.5%, P-value: 0.018).

Introduction: Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) was found in Wuhan China which caused the acute respiratory illness and became the pandemic as declared by World Health Organization on March 11, 2020. Viral inclusion bodies have been identified in endothelial cells in a variety of organs. Deep Vein Thrombosis(DVT) is one atypical presentation which is thought to be triggered by endothelial dysfunction and exacerbated by hypoxia in patients with COVID-19.

Methods: It was a single center retrospective study in Kathmandu University Dhulikhel Hospital. All the data were taken between January, 2020 till May, 2021 who were presented in OPD or inpatient department with symptoms of DVT and required admission. Presence or absence or concomitant COVID-19 was tested by RT-PCR test.

Result: There were a total of 52 patients admitted as DVT, among which 26(50%) were male and 26(50%) were female. Twenty patients (38.5%) were COVID-19 positive and 32 (61.5%) were COVID-19 negative. Mean age for among those patients was 50.50±4.8 years, average hospital stay was 6.4±0.6 days, after anticoagulation therapy target INR was reached in 3.8±0.17 days and CVI was present in 14(70%) for COVID positive with DVT. Similarly, mean age was 46.80±3.3 years, average hospital stay was 4.6±0.3 days, after anticoagulation therapy target INR was reached in 3.3±0.21 days and CVI was present in 18(56.65%) with COVID negative with DVT.

Conclusion: COVID-19 is still the mysterious virus and exact mechanism of this disease is still a debate which may need many years to solve. Sometimes DVT can be the only presentation of this disease

Introduction: Hemi facial spasm (HFS) and Blepharospasm (BS) is a chronic distressing condition. Botulinum toxin (BoNT) injection is one of its treatment modality. Acquiring the injection and treating the patients overcoming the lockdown hurdles of COVID pandemic has been a major challenge.

Methods: Patients who were treated at Tribhuvan University Teaching Hospital (TUTH) Outpatient Department (OPD) during the COVID pandemic in 2020 and 2021 were included in this study.

Results: Out of 30 patients, 77% were female. 47% were diagnosed with BS whereas the rest with HFS. About 50% of them have had symptoms for an average of 2-5 years before receiving botulinum toxin injection. The mean Jankovic score for patients before BoNT was 2.31(SD: 0.66 range 1-4). 26 patients experienced a decrease in spasm within one week of BoNT injection and had symptomatic relief. The mean Jankovic score at week 1 was 0.63(SD: 1.09 range 1-3) and the difference was statistically significant (p<0.001). After 2 weeks of BoNT therapy, all patients experienced a decrease in spasm with symptomatic improvement. The mean Jankovic score at week 2 was 0.26(SD: 0.44 range 0-1) and the difference was statistically significant (p<0.001). In terms of side effects, 4 patients experienced paresis while 26 patients experienced no side effects. No other systemic side effects were reported.

Conclusion: BoNT injection has a good outcome for HFS and BS, despite its cost and the need for frequent injection. Importing the BoNT from India during the lockdown period of COVID pandemic and patients travelling within the country were challenges that were faced by the patients and doctors to achieve the result.

Introduction: Humerus shaft fracture is a common injury representing 1.2-3% of all fractures. It can be managed both conservatively and operatively with various modalities. Among operative, plate osteosynthesis is the most widely accepted method of treatment when conservative treatment is not adequate to achieve union with good functional outcome. Anteromedial plating through anterolateral approach is a safe and reliable approach in plate osteosynthesis.

Methods: A prospective study was conducted in the Department of orthopaedics, Nepal APF hospital, Kathmandu from 2015 February to 2020 February. Forty-four patients who underwent anteromedial plating for humeral shaft fracture were included in the study. Patients were evaluated for functional recovery and progress of fracture healing. Rodrigeuz-Merchan criteria was used to grade the functional outcome.

Results: A total of 44 patients were included in the study with mean age of 36. There were 31 males and 13 females. The majority of patients 31 (70.45%) sustained injury due to road traffic accident followed by fall from height 11 (25%) and direct injury 2(4.55%). The most common fracture pattern was AO /OTA Type A. The mean duration of surgery was 60±15min. Fracture union occurred in less than 4 months in 36 patients (81.81%). Rodriguez Merchan criteria showed majority of the patients had excellent 23(52.27%) and good 15 (34.1%) functional outcomes.

Conclusion: Anteromedial plating provides a safe form of fixation of humeral shaft fracture. It has benefit of supine positioning of the patient during operation with good union rate, less fixation time, lesser complications leading to better functional outcome.

Alcohol is a socially acceptable and widely available drink in most countries. Its excessive consumption is linked to various health issues, increase in crime rate and even loss of life. This puts heavy strain in low-income countries like Nepal where full medical facilities are still out of reach for most of the population. Therefore, in this article, we have provided an overview of (i) the effect of alcohol on public health; (ii) trend data on alcohol seizures; (iii) alcohol (including methanol) positive forensic cases; and (iv) other alcohol associated crimes. Our analysis is drawn from a range of data types and sources, triangulating the collected data with alcohol specific academic and grey literature, a survey with students and insights from stakeholder engagements in Nepal. We have shown that alcohol has been associated with a range of health-related issues and crime types in Nepal. For example, alcohol was the most mentioned compound in the student survey (50.7%; n=418) followed by other drugs in Drugs Facilitated Sexual Assault cases. We have also discussed issues with adulteration, surrogates and sub-standard alcohol, highlighting the need for strict monitoring, regulations and extra vigilance about quality control of alcohol in circulation. This should be supported by public awareness campaigns on the use, abuse and impacts of alcohol.

Acute Ischemic Stroke (AIS) is a leading cause of death and disability. It can be treated early with a favorable prognosis if intravenous recombinant tissue plasminogen activator (IV rt-PA) is given to eligible patients within 4.5 hours of its onset. For those patients who do not meet the criteria to undergo intravenous fibrinolysis, mechanical thrombectomy has been shown to be an effective alternative in patients presenting with occlusion of first segment of middle Cerebral artery (MCA) or of internal carotid artery (ICA), provided the intervention is performed within 24 hour according to previous trial. We herein review different randomized controlled trials on AIS undergoing mechanical thrombectomy

Background: Craniopharyngioma, an epithelial tumor believed to arise from the remnants of Rathke’s pouch, portray approximately 1.2%-4.4% of all intracranial tumors. Due to its inherent domain in the skull base and its liaison with indispensable neurovascular structure, it has still remained an intimidating contest despite an improved dexterity among the neurosurgeons and refinement in neurosurgical gadgetry.Surgical corridor to come down in favor for is elected by the position of optic chiasm, extension of tumor and development of ACoM or ACA (A1).

Methods: A retrospective series study was conducted at Annapurna Neurological Institute and Allied Sciences between January 2016 and August 2021. A total of 20 patients who underwent surgery for histopathologically proven craniopharyngioma was enrolled. Majority of the surgery was performed via a pterional approach while two cases were addressed with a supra ciliary approach and one with a trans nasal trans septal transsphenoidal approach.

Result: The age of presentation among our study group ranged from 5 years to 46 years with a mean age of 28.2 years.The most frequent mode of presentation was headache associated with visual disturbances (visual acuity and visual field). Histopathological analysis disclosed an admantinomatous variant 15 cases and a papillary type in 5 cases. The use of Ommaya reservoir in few selective cases was escorted by the cystic ingredient of the lesion. An endeavor to aggressive surgical approach was accomplished, amidst, excision of tumor was subtotal in 9 %, near total in 36 % and gross total in 45 %. Diabetes insipidus was seen in 36%. We had to endure a case of mortality, who lamentably had a massive sub-arachnoid hemorrhage with a colossal PCA territory infarction on arrival. Post operatively, the mass effect evolved on account of PCA territory infarction.

Conclusion: The magnitude of resection of the tumor is affected by the extension of tumor, consistency of the lesion and position of optic chiasm. Even with an extensive resection, the prospect of recurrence is inordinately high.
