Abstract. Despite the implementation of the Clean Air Action Plan by the
Chinese government in 2013, the issue of increasing surface ozone (O3)
concentrations remains a significant environmental concern in China. In this
study, we used an improved regional climate–chemistry–ecology model
(RegCM-Chem-YIBs) to investigate the impact of anthropogenic emissions,
meteorological factors, and CO2 changes on summer surface O3
levels in China from 2008 to 2018. Compared to its predecessor, the model
has been enhanced concerning the photolysis of O3 and the radiative
impacts of CO2 and O3. The investigations showed anthropogenic
emissions were the primary contributor to the O3 increase in China,
responsible for 4.08–18.51 ppb in the North China Plain.
However, changed meteorological conditions played a crucial role in
decreasing O3 in China and may have a more significant impact than
anthropogenic emissions in some regions. Changed CO2 played a critical
role in the variability of O3 through radiative forcing and isoprene
emissions, particularly in southern China, inducing an increase in O3
on the southeast coast of China (0.28–0.46 ppb) and a
decrease in southwest and central China (−0.51 to −0.11 ppb). Our study comprehensively analyzed O3 variation across China from
various perspectives and highlighted the importance of considering CO2
variations when designing long-term O3 control policies, especially in
high-vegetation-coverage areas.
Estimation of extreme precipitation events in Estonia and Italy using dual-polarization weather radar quantitative precipitation estimations
Authors: Cremonini Roberto , Voormansik Tanel , Post Piia , Moisseev Dmitri
Published: June 2023

Abstract. Evaluating extreme rainfall for a certain location is commonly considered when designing stormwater management systems. Rain gauge data are widely used to estimate rainfall intensities for a given return period. However, the poor spatial and temporal resolution of operational gauges is the main limiting factor. Several studies have used rainfall estimates based on weather radar horizontal reflectivity (Zh), but they come with a great caveat: while proven reliable for low or moderate rainfall rates, they are subject to major errors in extreme rainfall and convective cases. It is widely known that C-band weather radar can underestimate precipitation intensity due to signal attenuation or overestimate it due to hail and clutter contamination. From the late 1990s, dual-polarization weather radar started to become operational in the national surveillance radar network in Europe, providing innovative quantitative precipitation estimation (QPE) based on polarimetric variables. This study circumvents Zh shortcomings by using specific differential-phase (Kdp) data from operational dual-polarization C-band weather radars. The rain intensity estimates based on a specific differential-phase data are immune to attenuation and less affected by hail contamination. In this study, for the first time, QPEs based on polarimetric observations by operational C-band weather radars and without any rain gauge adjustments are analyzed. The purpose is to estimate return periods for 1 h rainfall total computed from polarimetric weather radar data using non-adjusted QPEs based on R(Zh,Kdp) data and to compare the results with those derived using R(Zh) and rain gauge data. Only the warm period during the year is considered here, as most of the extreme precipitation events for such a duration occur for both places studied (Italy and Estonia) at this time. Limiting the dataset to warm periods also allows us to use the radar-based rainfall quantitative precipitation estimations, which are more reliable than the snowfall ones. Data from operational dual polarimetric C-band weather radar sites are used from both Italy and Estonia. Given climatologically homogeneous regions, this study demonstrates that polarimetric weather radar observations can provide reliable QPEs compared to single-polarization estimates with respect to rain gauges and that they can provide a reliable estimation of return periods of 1 h rainfall total, even for relatively short time series.

Abstract. We present a new version of O3 data retrieved from the three MIPAS observations modes of the middle atmosphere (MA, UA and NLC). The O3 profiles cover altitudes from 20 up to 100 km altitudes for daytime and up to 105 km at nighttime, for all latitudes, and the period 2005 until 2012. The data has been obtained with the IMK–IAA MIPAS level 2 data processor and are based on ESA version 8 re-calibrated radiance spectra with improved temporal stability. The processing included several improvements with respect to the previous version, such as the consistency of the microwindows and spectroscopic data with those used in the nominal mode V8 data, the O3 a priori profiles, and updates of the non-LTE parameters and of the nighttime atomic oxygen. Random errors are dominated by the measurement noise with 1σ values for single profiles for daytime of <5 % below ~60 km, 5–10 % between 60 and 70 km, 10–20 % at 70–90 km and about 30 % at 95 km. For nighttime, they are very similar below 70 km but smaller above (10–20 % at 75–95 km, 20–30 % at 95–100 km and larger than 30 % above 100 km). The systematic error is ~6 % below ~60 km (dominated by uncertainties in spectroscopic data), and 8–12 % above ~60 km, mainly caused by non-LTE uncertainties. The systematic errors in the 80–100 km range are significantly smaller than in the previous version. The major differences with respect to the previous version are: 1) The new retrievals provide O3 abundances in the 20–50 km altitude range larger by about 2–5 % (0.2–0.5 ppmv); 2) O3 abundances reduced by ~2–4 % between 50 and 60 km in the tropics and mid-latitudes; 3) reduced O3 abundances in the nighttime O3 minimum just below 80 km, leading to a more realistic diurnal variation; 4) larger daytime O3 concentrations in the secondary maximum at the tropical and mid-latitudes (~40 %, 0.2–0.3 ppmv); and 5) nighttime O3 abundances in the secondary maximum reduced by 10–30 %. The O3 profiles retrieved from the nominal mode (NOM) and the middle atmosphere modes are fully consistent in their common altitude range (20–70 km). Only at 60–70 km daytime O3 of NOM seems to be larger than that of MA/UA by 2–10 %. Compared to other satellite instruments, MIPAS seems to have a positive bias of 5–8 % below 70 km. Noticeably, the new version of MIPAS agrees much better than before with all instruments in the upper mesosphere/lower thermosphere, reducing the differences from ~ ±20 % to ~ ±10 %. Further, the diurnal variation of O3 in the upper mesosphere (near 80 km) has been significantly improved.
Multi-decadal pacemaker simulations with an intermediate-complexity climate model
Authors: Molteni Franco , Kucharski Fred , Farneti Riccardo
Published: June 2023

Abstract. In this paper, we first describe the main features of a new version of the International Centre for Theoretical Physics global atmospheric model (SPEEDY) with improved simulation of surface fluxes, and the formulation of a 3-layer thermodynamic ocean model (TOM3) suitable to explore the coupled extratropical response to tropical ocean variability. Then, we present results on the atmospheric model climatology, highlighting the impact of the modifications introduced in the model code, and show how important features of interdecadal and interannual variability are simulated in a “pacemaker” coupled ensemble of 70-year runs, where portions of the tropical Indo-Pacific are constrained to follow the observed variability. Despite the very basic representation of variations in greenhouse forcing and heat transport to the deep ocean (below the 300 m domain of the TOM3 model), the coupled ensemble reproduces the variations in surface temperature over land and sea with very good accuracy, confirming the role of the Indo-Pacific as a “pacemaker” for the natural fluctuations of global- mean surface temperatures found in earlier studies. Atmospheric zonal-mean temperature trends over 50 years are also realistically simulated in the extratropical lower troposphere and up to 100 hPa in the tropics. On the interannual scale, SST variability in sub-tropical and tropical regions not affected by SST relaxation is underestimated (mostly because of the absence of dynamically induced variability), while extratropical SST variability during the cold seasons is comparable to observed statistics. Atmospheric teleconnections patterns and their connections with SST are reproduced with high fidelity, although with local differences in the amplitude of regional features (such as a larger-than-observed response of extratropical SST to North Atlantic Oscillation variability). The SPEEDY-TOM3 model also reproduces the observed connection between averages of surface heat fluxes over the oceans and land surface air temperature in the wintertime northern extratropics. Overall, as in earlier versions of SPEEDY, the fidelity of the simulations (both in terms of climatological means and variability) is higher near the surface and in the lower troposphere, while the negative impacts of the coarse vertical resolution and simplified parametrizations are mostly felt in the stratosphere. However, the improved simulation of surface heat fluxes and their impact on extratropical SST variability in this model version (obtained at a very modest computational cost) make the SPEEDY-TOM3 model a suitable tool to investigate the coupled response of the extratropical circulation to interannual and inter-decadal changes of tropical SST in ensemble experiments.
Subgridding High Resolution Numerical Weather Forecast in the Canadian Selkirk range for local snow modelling in a remote sensing perspective
Authors: Billecocq Paul , Langlois Alexandre , Montpetit Benoit
Published: June 2023

Abstract. Snow Water Equivalent (SWE) is a key variable in climate and hydrology studies. Current SWE products mask out high topography areas due to the coarse resolution of the satellite sensors used. The snow remote sensing community is hence pushing towards active microwaves approaches for global SWE monitoring. However, designing a SWE retrieval algorithm is not trivial, as multiple combinations of snow microstructure representations and SWE can yield the same radar signal. The community is converging towards forward modeling approaches using an educated first guess on the snowpack structure. Yet, snow highly varies in space and time, especially in mountain environments where the complex topography affects atmospheric and snowpack state variables in numerous ways. Automatic Weather Stations (AWS) are too sparse, and high-resolution Numerical Weather Predictions systems have a maximal resolution of 2.5 km × 2.5 km, which is too coarse to capture snow spatial variability in a complex topography. In this study, we designed a subgridding framework for the Canadian High Resolution Deterministic Prediction System. The native 2.5 km × 2.5 km resolution forecast was subgridded to a 100 m × 100 m resolution and used as the input for snow modeling over two winters in Glacier National Park, British Columbia, Canada. Air temperature, relative humidity, precipitation and wind speed were first parameterized regarding elevation using six Automatic Weather Stations. Alpine3D was then used to spatialize atmospheric parameters and radiation input accounting for terrain reflections and perform the snow simulations. Modeled snowpack state variables relevant for microwave remote sensing were evaluated against profiles generated with Automatic Weather Stations data and compared to raw HRDPS driven profiles. Overall, the subgridding framework improves the optical grain size (OGS) bias by 0.04 mm, the density bias by 2.7 kg · m−3 and the modelled SWE by 17 % (up to 41 % in the best case scenario). Overall, this work provides the necessary basis for SWE retrieval algorithms using forward modeling in a Bayesian framework.
Examining the dynamics of a Borneo vortex using a balance approximation tool

Published: June 2023

Abstract. Cyclonic vortices that are weaker than tropical storm category can bring heavy precipitation as they propagate across the South China Sea and across surrounding countries. Here we investigate the structure and dynamics responsible for the intensification of a Borneo vortex that moved from the north of Borneo across the South China Sea and impacted Vietnam and Thailand in late October 2018. This case study is examined using Met Office Unified Model (MetUM) simulations and an idealised semi-geotriptic (SGT) balance approximation tool. Satellite observations and a MetUM simulation with 4.4 km grid initialised at 12 UTC on 21 October 2018, show that the westward-moving vortex is characterised by a coherent maximum in total column water, and by a comma-shaped precipitation structure with the heaviest rainfall to the northwest of the circulation centre. The Borneo vortex is comprised of a low-level cyclonic circulation and a mid-level wave embedded in the background easterly shear flow, which strengthens with height up to around 7 km. Despite being in the Tropics at 6º N, the low-level vortex and mid-level wave are well represented by SGT balance dynamics. The mid-level wave propagates along a vertical gradient in moist stability, i.e., the product between the specific humidity and the static stability, at 4.5 to 5 km and is characterised by a coherent signature in the potential vorticity, meridional wind, and balanced vertical velocity fields. The vertical motion is dominated by coupling with diabatic heating and in quadrature with the potential vorticity so that the diabatic wave propagates westwards, relative to the flow, at a rate consistent with prediction from moist semi-geostrophic theory. Initial vortex development at low levels is consistent with baroclinic growth initiated by the mid-level diabatic Rossby wave, which propagates on baroclinic shear flow on the southern flank of a large-scale cold surge.

Abstract. We investigate the use of oxygen (O2) and carbon dioxide (CO2) measurements for the estimation of the fossil fuel component of atmospheric CO2 in the UK. Atmospheric potential oxygen (APO) – a tracer that combines O2 and CO2, minimising the influence of terrestrial biosphere fluxes – is simulated at three sites in the UK, two of which make atmospheric APO measurements. We present a set of model experiments that estimate the sensitivity of APO simulations to key inputs: fluxes from the ocean, fossil fuel flux magnitude and distribution, the APO baseline, and the ratio of O2 to CO2 fluxes from fossil fuel combustion and the terrestrial biosphere. To estimate the influence of uncertainties in ocean fluxes, we compared three ocean O2 flux estimates, from the NEMO – ERSEM and ECCO-Darwin ocean models, and the Jena CarboScope APO inversion. The sensitivity of APO to fossil fuel emission magnitudes and to terrestrial biosphere and fossil fuel exchange ratios was investigated through Monte Carlo sampling within literature uncertainty ranges, and by comparing different inventory estimates. Of the factors that could potentially compromise APO-derived fossil fuel CO2 estimates, we find that the ocean O2 flux estimate has the largest overall influence at the three sites in the UK. At times, this influence is comparable to the contribution to APO of simulated fossil fuel CO2. We find that simulations using different ocean fluxes differ from each other substantially, with no single model estimate, or a simulation with zero ocean flux, providing a significantly closer fit to the observations. Furthermore, the uncertainty in the ocean contribution to APO could lead to uncertainty in defining an appropriate regional background from the data. Our findings suggest that the contribution of non-terrestrial sources need to be well accounted for, in order to reduce their potential influence on inferred fossil fuel CO2.
Rate-induced tipping in natural and human systems

Published: June 2023

Abstract. Over the last 2 decades, tipping points in open systems subject to changing external conditions have become a topic of a heated scientific debate due to the devastating consequences that they may have on natural and human systems. Tipping points are generally believed to be associated with a system bifurcation at some critical level of external conditions. When changing external conditions across a critical level, the system undergoes an abrupt transition to an alternative, and often less desirable, state. The main message of this paper is that the rate of change in external conditions is arguably of even greater relevance in the human-dominated Anthropocene but is rarely examined as a potential sole mechanism for tipping points. Thus, we address the related phenomenon of rate-induced tipping: an instability that occurs when external conditions vary faster, or sometimes slower, than some critical rate, usually without crossing any critical levels (bifurcations). First, we explain when to expect rate-induced tipping. Then, we use three illustrative and distinctive examples of differing complexity to highlight the universal and generic properties of rate-induced tipping in a range of natural and human systems.

Published: June 2023

Abstract. This paper describes a new global dataset of cloud properties observed by MODIS relying on the current (collection 6.1) processing of MODIS data and produced to facilitate comparison with results from the MODIS observational proxy used in climate models. The dataset merges observations from the two MODIS instruments into a single netCDF file. Statistics (mean, standard deviation, and number of observations) are accumulated over daily and monthly timescales on an equal-angle grid for viewing and illumination geometry, cloud detection, cloud-top pressure, and cloud properties (optical thickness, effective particle size, and water path) partitioned by thermodynamic phase and an assessment as to whether the underlying observations come from fully or partly cloudy pixels. Similarly partitioned joint histograms are available for (1) optical thickness and cloud-top pressure, (2) optical thickness and particle size, and (3) cloud water path and particle size. Differences with standard data products, caveats for data use, and guidelines for comparison to the MODIS simulator are described. Data are available on daily (https://doi.org/10.5067/MODIS/MCD06COSP_D3_MODIS.062; NASA, 2022b) and monthly (https://doi.org/10.5067/MODIS/MCD06COSP_M3_MODIS.062; NASA, 2022a) timescales.
Adding sea ice effects to a global operational model (NEMO v3.6) for forecasting total water level: approach and impact
Authors: Wang Pengcheng , Bernier Natacha B.
Published: June 2023

Abstract. In operational flood forecast systems, the effect of sea ice is typically neglected or parameterized solely in terms of ice concentration. In this study, an efficient way of adding ice effects to the global total water level prediction systems, via the ice–ocean stress, is described and evaluated. The approach features a novel, consistent representation of the tidal relative ice–ocean velocities, based on a transfer function derived from ice and ocean tidal ellipses given by an external ice–ocean model. The approach and its impact are demonstrated over four ice seasons in the Northern Hemisphere, using in situ observations and model predictions. We show that adding ice effects helps the model reproduce most of the observed seasonal modulations in tides (up to 40 % in amplitude and 50∘ in phase for M2) in the Arctic and Hudson Bay. The dominant driving mechanism for the seasonal modulations is shown to be the under-ice friction, acting in areas of shallow water (less than 100 m) and its accompanied large shifts in the amphidromes (up to 125 km). Important contributions from baroclinicity and tide–surge interaction due to ice–ocean stress are also found in the Arctic. Both mechanisms generally reinforce the seasonal modulations induced by the under-ice friction. In forecast systems that neglect or rely on simple ice concentration parameterizations, storm surges tend to be overestimated. With the inclusion of ice–ocean stress, surfaces stresses are significantly reduced (up to 100 % in landfast ice areas). Over the four ice seasons covered by this study, corrections up to 1.0 m to the overestimation of surges are achieved. Remaining limitations regarding the overestimated amphidrome shifts and insufficient ice break-up during large storms are discussed. Finally, the anticipated trend of increasing risk of coastal flooding in the Arctic, associated with decreasing ice and its profound impact on tides and storm surges, is briefly discussed.

Illuminating historical causal reasoning: Designing a theory-informed cognition model for assessment purposes
Authors:   University of Amsterdam, Das Rozendal Uddhava , van Boxtel Carla ,   University of Amsterdam
Published: June 2023

This study presents a theory-informed cognition model of causal reasoning in history as a foundation for assessment tasks. This model details the levels of achievement of individuals’ causal reasoning in history and the underlying beliefs and knowledge types that should be mastered to become proficient in this form of reasoning. The model was developed following a design approach. First, a literature study was conducted on the nature of causation in history. This study led to the creation of an initial model that was submitted to two mixed expert panels comprising experts from various backgrounds who critiqued the model. Based on their feedback, the model was further refined. This process resulted in a description of levels of achievement for three dimensions: an epistemic dimension, a second-order knowledge dimension and a first-order knowledge dimension. For each dimension, we identified concrete behaviour and underlying knowledge and beliefs. This cognition model can form the foundation for developing assessment tasks that can help improve students’ causal reasoning in history.

Parallel-in-time algorithms are more and more recognized as a promising solution to increase computational concurrency after the maximum speed-up has been achieved from spatial parallelism due to communication overhead when the problem size per processor has become too small in distributed memory high-performance computing architecture. Two popular time-parallel approaches are the Parareal algorithm, first introduced by Lions et al. (2001), and the Parallel Full Approximation Scheme in Space and Time (PFASST) technique of Emmett and Minion (2012). Both methods are based on the use of multi-level time-integration, exploiting a fine and a coarse time integrators in combination with an iterative procedure to achieve parallelism in time. The implementation of these two parallel-in-time algorithms in the Nektar++ spectral/hp element framework is described. The extension of the MPI topology to allow concurrency in time is first presented. Following, the implementation of new drivers for the Parareal and PFASST algorithms is described. Finally, application examples for the 1D advection and the 2D diffusion equations are demonstrated.

Is the grass greener on the other side? Adventures with the least-squares finite element method

The least-squares finite element method (LSFEM) emerged as an alternative to classical Galerkin FEM around 30 years ago. Since then, it has successfully found applications in many fields of computational physics, including fluid dynamics. The method possesses some desirable properties – it always leads to symmetric, positive-definite algebraic systems (even for non-self-adjoint operators), it does not necessitate the fulfillment of compatibility (LBB) conditions, and it is generally more stable than its classical counterpart. Conversely, it requires recasting equations to the first order (introducing additional degrees of freedom) and involves a more computationally expensive assembly procedure. This talk will attempt to evaluate whether the benefits of LSFEM outweigh its drawbacks and offer a practical perspective on how it can be employed to efficiently solve incompressible flow problems. We will show an alternative equation splitting scheme, which, in conjunction with LSFEM, leads to an enhanced convergence rate. Finally, we will discuss computational aspects of the method using the author’s high-order code L3STER as a point of reference. In particular, we will show how to structure assembly so that it fully utilizes CPU caches, and how hybrid parallelism can be leveraged for improved scalability.

Near infrared spectroscopy (NIRS) was used to discriminate the quality level of Yongchuan Xiuya tea quickly and nondestructively. Three quality levels of Yongchuan Xiuya tea were collected, then scanning NIRS, pretreating spectral noise information, screening characteristic spectral intervals by backward interval partial least squares, proceeding principal component analysis. Last, the jump connection nets artificial neural network (J-BP-ANN) with three kinds of transfer functions was applied to establish models. The best pretreated method was the combination of multivariate scattering correction and the first derivative. Six characteristic spectral intervals were screened, which accounting for 27.23% spectral data. The cumulative contribution rate of the first three principal components of the selected characteristic spectra was 97.85%. When the J-BP-ANN calibration set model was established with the tanh function, NIRS model had the best results, whose root mean square error and determination coefficient of the cross validation were 0.953 and 0.031, respectively. The root mean square error and the determination coefficient of the prediction set model were 0.942 and 0.041, respectively. The absolute deviation values of prediction set samples were <0.08. The results showed NIRS can predict the quality levels of Yongchuan Xiuya tea quickly and accurately.

In traditional apprenticeship-training methods, students in health professions programs deal with real-world scenarios that test their knowledge and abilities like other physicians do.1 Assessment models must protect patients and give trainees contextual feedback2. Objective Structured Clinical Examinations (OSCEs), developed first by Ronald Harden while working at Dundee’s utilized in numerous teaching sectors for decades3. Assessments have limitations. Because of the nature of the stations, the doctor-patient encounter is generally broken down into its component parts, and the types of instances that can be repeated restrict patient concerns.4Many clinical lengthy case examination adjustments have been presented for viable answers. WPBA evaluates workplace clinical practices. It evaluates doctors' practices. WPBA evaluates clinical trainees and provides comments. WBA has made the switch from numbers-based experience to organized assessment possible5. The General Medical Council; UK & Royal Colleges use WPBA to evaluate postgraduate medical students. In undergraduate medical education, WPBA is becoming popular.

Published: June 2023

Background: The coronavirus 2019, also known as SARS-CoV-2, is highly contagious and spreads easily through respiratory droplets when an infected person coughs or sneezes. In December 2019 Wuhan China, the virus was first detected and has become a global pandemic. Aim: To maintain an evidence-based ophthalmology practice during the Covid-19 pandemic, some strategies and guidelines that may be considered and to adapt their practices to the challenges presented by the Covid-19 pandemic while still maintaining evidence-based care. Methods: This narrative review study was conducted in ophthalmology department of Akbar Niazi Teaching Hospital (ANTH), Islamabad between January and March 2023. Some guidelines during Covid-19 outbreak were discussed. Results: Identifying and addressing challenges in different care settings is important for maintaining high-quality ophthalmology care during the Covid-19. Minimizing cross-infection of Covid-19 is essential in healthcare settings to protect both healthcare workers and patients. Stringent infection control measures with personal protective equipment (PPE) and routine cleaning of "high-touch" surfaces, are important strategies to reduce the risk of transmission. Implementing a stringent dual screening and triaging process is a crucial step for outpatient care during the Covid-19 pandemic. This helps to identify high-risk patients and provide appropriate care while minimizing the risk of transmission to other patients and healthcare workers. Separating inpatient and outpatient care is another important strategy to minimize interactions and reduce the risk of transmission of Covid-19. Planning logistics and manpower is critical during the Covid-19 pandemic to ensure that healthcare facilities have the necessary resources and staff to meet the needs of patients. The practical implication of this review was to develop strategies for safe routine eye care and surgery to maintain practice. Conclusion: The measures implemented in response to the Covid-19 in ophthalmology clinics can serve as a guide for healthcare facilities facing similar disease outbreaks in the future. Keywords: Challenges; Evidence-based practice; Ophthalmology; SARS-CoV-2.

Aim: To examine and compare side effects of intravenous Labetalol and Hydralazine in the treatment of Hypertension in pregnancy in developing countries like Pakistan. Methodology: A six-month randomised controlled experiment was undertaken at the Lady Aitchison Hospital's, Department of Obstetrics and Gynaecology. In the study, 330 individuals with severe hypertension who were between the ages of 20 and 35 years old and had been pregnant for more than 20 weeks were included. Patients were split into two groups of equal size. Group A was administered a 20mg IV bolus of Labetalol while Group B was administered a 5-10mg IV bolus of Hydralazine. The patients were monitored during the administration period of 60 minutes and all this data was entered into a proforma. Results: Females had an average age of 27.43±3.47 years and average gestational age in females was 28.98±4.49 weeks. The systolic blood pressure in all females was 109.43 ±16.93mmHg after 60 minutes of therapy, and mean diastolic blood pressure was 77.28±14.73mmHg. A total of 135(40.9%) women suffered from maternal hypotension [27(16.36%) with Labetalol vs 108(65.43%) with Hydralazine], and 55(16.68%) females exhibited abnormal fetal heart rate [1 (0.61%) with Labetalol and 54(32.72%) with Hydralazine]. Therefore, the Hydralazine adverse effect was statistically significant (p-value = 0.000). Practical Implication: If the results of this study are applied in clinical practice in patients of pregnancy induced hypertension, female patients ca be prevented of side effects of hydralazine by using labetalol to treat hypertension in pregnancy, so it is very beneficial for patients. Conclusion: The study concludes that use of Hydralazine in females with PIH should be discouraged, whereas the use of Labetalol should be encouraged in a developing country like Pakistan.

Aim: To assess the usage of Remdesivir in COVID 19 patients admitted to Mayo hospital Lahore Methods: This Quasi experimental study was carried out in COVID-19 ward from July 2020 to September 2020 on patients presenting to Mayo Hospital with COVID-19.The sample size (n=150) was calculated through non-probability convenient sampling technique. We gave intravenous Remdesivir to hospitalized COVID-19 patients with proven SARS-CoV-2 infection with an oxygen saturation of ≤94% who were breathing ambient air or needed oxygen support and had an oxygen saturation of less than 94%. Remdesivir was administered to patients over the course of a 10-day course, starting with 200 mg intravenously (I/V) on day 1 and continuing with 100 mg per day for the following nine days. Results: Among 150 participants in our study, 103 (69%) were male and 47(31.3%) were females. Mean age was 57.37±13.42years. Selected parameters were evaluated at day 1, 5 and 10. Significant improvement in fever, dyspnea score, serum C- Reactive proteins (CRP) and lactate dehydrogenase (LDH) was found on day 1 and 10 with a p value of 0.01 to 0.000 for CRP and 0.48 to 0.000 for LDH respectively. Serum ferritin also showed a statistical difference with a significant p value of 0.038 at day 10 as compared to day 1 and 5. Conclusion: Among patients presenting with severe Covid-19, clinical improvement was noticed earlier in those who received Remdesivir than those who didn’t receive this drug. Measurement of effectiveness will require ongoing randomized controlled trials of Remdesivir drug therapy.
