CytoSorb on the Septic Shock

Background: Septic shock, defined as organ dysfunction caused by a dysregulated host response to infection, is a condition associated with high morbidity and mortality. One of the hallmarks of sepsis is the excessive release of cytokines and other inflammatory mediators that cause septic shock and multi-organ failure (MOF). New adsorbents are now available as adjuvant therapy aimed at modulating the cytokine "storm" in sepsis. They are thought to be useful if adopted early (within 8-24 hours of the diagnosis of septic shock) in patients who are unresponsive to standard therapy. Here we report our experience with CytoSorb. Method(s): From January 2021 to May 2022, 46 patients with septic shock were treated with continuous renal replacement therapy (CRRT) associated with hemoadsorption with CytoSorb. All cases presented organ failure including AKI. Surgical patients (n = 13) were treated with surgery, COVID patients (n = 15) and medical patients (n = 16) with medical therapy;all surgery cases were operated on before starting the haemadsorption and in some cases reoperation with the need to suspend the adsorption. The mean age was 69 +/- 17 years (SD). On admission the mean SAPSII score was 50 +/- 11 (SD). CRRT as hemodiafiltration (CVVHDF) was performed. All patients received at least one CytoSorb treatment and additional treatments (up to 21 filters in a Covid patient) according to our indication. The CytoSorb cartridge was installed in series to the high cut-off filter;blood flow rates were maintained between 120 and 150 mL/min while dialysis doses from 18 to 45 mL/kg/hour. CytoSorb was renewed every 24 hours. We evaluated the impact of CytoSorb on 30-day survival, haemodynamics and relevant outcomes. Result(s): The 30-day survival was 30%. During treatment with CytoSorb, patients had a hemodynamic stabilization with a significant improvement in MAP, a reduction in amines and a decrease in PCR and PCT (Figure 1). Mortality at 30 days among medical patients was almost comparable to that of COVID patients and higher than that of surgical patients (70%, 69% and 61%, respectively). It should be noted that almost half of the deceased patients arrived late in the hospital, thus leading to a late start of treatment. Conclusion(s): We confirm the efficacy and usefulness of the CytoSorb if adopted early in patients who do not respond to standard therapy. CytoSorb treatment was safe and well tolerated with no device-related adverse events during or after treatment sessions.

A Study on Establishing Thermal Output Conditions of Radiant Ceiling Heating Panels for Improving Thermal Comfort of Perimeter Zone in Buildings

Amid concerns over airflow-induced transmission of the COVID-19 virus in buildings frequented by large numbers of people, such as offices, the necessity for radiant ceiling heating panels has increased. This is due to the concern that the airflows emitted from the convection heating systems installed near the ceiling or windows for winter heating may be a major cause of COVID-19 transmission. In this study, we aim to evaluate thermal comfort under various indoor and outdoor environmental conditions of a building and present the thermal output conditions of the radiant ceiling heating panel that can replace the convection heating system while ensuring comfort in the perimeter zone and handling the heating load. As a result, we were able to present, in a chart format, the thermal output conditions that can secure thermal comfort by analyzing the indoor airflow distribution depending on the surface temperature of the radiant ceiling heating panel, the interior surface temperature of the window, and the influence of internal heat generation. Moreover, through derived empirical formulas, we were able to determine the heating conditions of the panel that can secure the necessary heat dissipation while minimizing discomfort, such as downdrafts, even for indoor and outdoor conditions that were not evaluated in this study.

ICU follow-up clinic provides the opportunity to recognise and address symptoms post critical illness, which may otherwise have been missed

Introduction: It is well documented that survivors of ICU admissions struggle to return to pre-admission level of function because of both physical and psychological burden. Current guidance therefore recommends a follow-up service to review patients 2-3 months post discharge [NICE 2009]. Prior to 2020 University Hospitals Bristol and Weston had no such service. With the increase in patient numbers seen during the COVID-19 pandemic, funding was received to provide a follow-up clinic to COVID-19 survivors. Objective(s): To provide a service that supports and empowers patients with their recovery from critical illness. Improving quality of life, speed of recovery and reducing longer term health care needs. Method(s): Referral criteria for the clinic included COVID-19 patients who received advanced respiratory support within intensive care and the high dependence unit. 8 weeks post discharge patients had a telephone appointment where ongoing symptoms could be identified. Advice around recovery, signposting to resources and onward referrals to appropriate specialities were provided. At 10 weeks post discharge patients had lung function tests and a chest X-ray which were reviewed by respiratory consultants. Based on the combination of these assessments, patients would be discharged or referred into the multidisciplinary team (MDT) follow-up clinic. The face to face clinic consisted of appointments with an intensivist, clinical psychologist, physiotherapist, and occupational therapist. Where needed patients would also be seen by a speech and language therapist or dietitian. Patients were seen only once in follow up clinic but again would be referred onto appropriate services within trust or the community, including but not exclusively community therapy services, secondary care services, SALT, dietetic or psychology clinics. Result(s): One of the key outcomes was the need for 147 onward referrals (an average of 1.13 referrals per patient). This included, 31 referrals to musculoskeletal physiotherapy outpatients for problems originating or made worse by their admission. 20 referrals to secondary care, including cardiology and ENT. 16 referrals to community occupational therapy, for provision of equipment, home adaptations and support in accessing the community. Subjectively, patient feedback was excellent. When asked what they felt was the most valuable thing they had taken from the clinic they reported: "Reassurance";"To know I'm not alone, others feel like this";"They listened to me and gave advice";"The ability to ask anything I wanted and the obvious kindness and support from all the clinicians I saw". Conclusion(s): Onward referral rates made by the follow-up clinic highlight the many issues faced by patients following discharge from ICU and hospital. With timely recognition and management, we can prevent a majority of these symptoms manifesting into chronic problems. This has the potential to lower the long-term burden on health care and improve quality of life for patients in both the short and long term. Without the follow-up clinic, these issues may have been missed or delayed. This reinforces the importance of the follow-up clinic and the need for ongoing investment.

The application experience of focused ultrasound heart examination in patients with COVID-19 in Prone-position.

Aim of the study. To study the experience of using focused transthoracic echocardiography in patients with COVID-19 in prone position (fEchoPr) in intensive care units (ICU). Materials and methods. The retrospective observational study included 53 patients (period from 15 April to 31 December 2020). Inclusion criteria: confirmed diagnosis of COVID-19, availability of fEchoPr data, outcome certainty (discharge/death). We analyzed electronic medical records. The fEchoPr was performed in patients in the prone position with a bolster under the left side of the chest and left arm raised ('swimmer's position'). We assessed the systolic function of the right ventricle (RV) (tricuspid annular plane systolic excursion (TAPSE)), RV size, RV/LV ratio, systolic function of the left ventricle (LV) (left ventricular outflow tract velocity time integral. (LVOT VTI)), and pulmonary hypertension (PH) (tricuspid regurgitation peak gradient (PGTR). Depending on the results, the patients were divided into 2 groups: informative (+fEchoPr) and non-informative (-fEchoPr) examinations. Results. There was no statistically significant difference in the groups (+fEcho n = 35 vs -fEcho n = 18) by age (65.6 +/- 15.3 vs 60.2 +/- 15.8, p > 0.05), by gender (male: 23 (65.7%) vs 14 (77.8%), p > 0.05), by body mass index (31.3 +/- 5.3 kg/m2 vs 29.5 +/- 5.4 kg/m2, p > 0.05), by mechanical ventilation support (24 (68.6%) vs 17 (94.4%), p = 0.074), by NEWS scale indicators (6.9 +/- 3.7 vs 8.5 +/- 3.5 points), by mortality (82.8% vs 94.4%, p > 0.05). Correlation analysis revealed a moderate inverse relationship between being on mechanical ventilation and the informative value of the study (Spearman's r = -0.30 at p = 0.033). In the +fEchoPr group, the correct measurement of TAPSE and RV/LV was carried out in 100%: a decrease in RV systolic function was recorded in 5 patients (14%), expansion of the RV in 13 patients (37%). Signs of PH were detected in 11 patients (31%), PGTR could not be measured in 10 patients (28%). LV systolic dysfunction was detected in 7 patients (20%). No pathology was detected in 16 patients (46%). One patient was diagnosed with infective endocarditis of native mitral valve, which was later confirmed by autopsy. Conclusion. In 66% of cases, fEchoPr examinations were informative, especially in terms of assessing the state of the right heart. fEchoPr examination is an affordable, valid and reproducible method to assess and monitor the state of the heart in ICU patients.Copyright © 2021 VIDAR Publishing House.

Key Allosteric and Active Site Residues of SARS-CoV-2 3CLpro Are Promising Drug Targets.

The main protease of SARS-CoV-2, 3-chymotrypsin-like protease (3CLpro), is a prominent target for antiviral development due to its essential role in the viral life cycle. Research has largely focused on competitive inhibitors of 3CLpro that target the active site. However, allosteric sites distal to the peptide substrate-binding region are also potential targets for the design of reversible noncompetitive inhibitors. Computational analyses have examined the importance of key contacts at allosteric sites of 3CLpro, but these contacts have not been validated experimentally. In this work, four druggable pockets spanning the surface of SARS-CoV-2 3CLpro were predicted: pocket 1 is the active site, whereas pockets 2, 3, and 4 are located away from the active site at the interface of domains II and III. Site-directed alanine mutagenesis of selected residues with important structural interactions revealed that 7 of 13 active site residues (N28, R40, Y54, S147, Y161, D187 and Q192) and 7 of 12 allosteric site residues (T111, R131, N133, D197, N203, D289 and D295) are essential for maintaining catalytically active and thermodynamically stable 3CLpro. Alanine substitution at these key amino acid residues inactivated or reduced the activity of 3CLpro. In addition, the thermodynamic stability of 3CLpro decreased in the presence of some of these mutations. This work provides experimental validation of essential contacts in the active and allosteric sites of 3CLpro that could be targeted with competitive and noncompetitive inhibitors as new therapeutics against COVID-19.

Numerical Analysis of the Impact of the Use of Personal Protective Equipment on the Face in the Process of Pollutants Spreading Emitted During Breathing

The study presents the results of a numerical analysis of the effectiveness of the use of personal protective equipment of various designs on the spread of pollutants marked with CO2 emitted during human breathing. In the study of 3D geometry the upper part of the human torso and head was developed. The simulated person was supplied with different personal protective equipment covering the human face (PPE). Two types of face shields worn at a different distance from the face and one fabric face mask was analysed. The reference geometry with no personal protective equipment was also analysed. Transient calculation with full breathing model including breath-in and breath-out and species transport were simulated. The results showed that different PPE generates different airflow patterns in the vicinity of the human face. The most efficient in reducing infection risk is by wearing a face mask or face shields at a small distance from the face, as they most effectively reduce CO2 concentration in the surrounding air. However, they also increase the re-inhalation risk of high CO2 concentration which affects human well-being.

Just Keep Swimming...Just Keep Swimming

History: We present a 15-year-old right hand dominant high school swimmer with no significant past medical history, who complains of right elbow pain along the distal biceps' tendon for a 2 months. Pain was insidious in onset, sharp, intermittent, and described as a 0 to 6 out of 10. The patient has been swimming more frequently over the last few months to prepare for competition and noticed progressive pain with swimming. He went on vacation and then was diagnosed with a COVID-19 infection and took an additional 2 weeks off due to fatigue. He returned to sport without re-integration and increased his swimming intensity to 1 to 2 hours daily, which worsened his pain. Performing the butterfly and breaststroke provoke symptoms and cessation of activity reduces the pain. Denies pain at rest. He took Advil which did not reduce his pain. Denies acute trauma, prior injuries, or paresthesias. Physical Exam: Inspection of right elbow: no swelling or signs of discoloration. Palpation: Tenderness at the distal biceps tendon but can hook the tendon without pain. No shoulder or wrist tenderness. Active Range of Motion: Elbow extension 0 degrees, elbow flexion 130 degrees, supination and pronation normal. Normal shoulder and wrist ROM. Muscle strength: 5/5 grip, wrist extension, and wrist flexion. Pain elicited with resisted elbow flexion at the distal humerus. Maneuvers: pain with distal humerus squeeze. Negative Maudsley and negative Cozen test. Differential Diagnosis: 36. Distal Biceps Tendonitis/Tear 37. Stress Reaction of the Distal Humerus 38. Medial Epicondyle Apophysitis 39. Capitellar Osteochondritis Dissecans 40. Radiocapitellar Plica Syndrome Test Results: x-ray right elbow: AP and Lateral views indicate no abnormalities to the bones, alignment, or soft tissue structures. MRI right elbow No IVCON: Biceps tendon intact. There is periosteal edema and endosteal aspect marrow edema along the medial aspect of the distal diaphysis and metaphysis of the humerus. Several small foci of increased cortical signal. No fractures, joint effusion, or chondral defects. Findings comparable to Fredrickson grade 4a distal humerus diametaphysis stress injury. Final Diagnosis: Right Elbow Supracondylar Grade 4a Stress Reaction. Discussion(s): Actives that involve repetitive motion are susceptible to overuse injuries. Cases of upper extremity stress reactions in swimmers have been documented along the inferior angle of the scapula, upper ribs, and olecranon. Stress reactions along the distal humerus in swimmers is not well documented. This pathology has been seen in baseball players, cricket bowlers, and tennis players. In swimming, the butterfly technique requires significant endurance and athletic strength. During a sprint, fast synchronized upper extremity revolutions occurring up to 60 cycles perminute counterforcewater surface area friction leading to excessive loading forces even at 50 meter distances. Outcome(s): The patient was withheld from upper body work outs and swimming for 6 weeks. VitaminDand Calcium levels were drawn revealing a normal calcium level (10.2), but a vitamin D level of 28.1. Patient was started on 600 IU of Vitamin D and 1300 mg of Calcium daily. The patient started a return to swim program and returned to full competition at 7 months post presentation. Follow-Up: At 6 weeks, started an upper extremity low impact non-aquatic physical therapy program. Then a slow progressive return to swimming was initiated at 50% effort for 4 weeks. At 10 weeks, a return to sport plan including 200 m all strokes except butterfly, progressed to 250 m at week 2, 300 m at week 3, and 350 m at week 4. Finally, initiated speed work in =0 to 100 m increments and elbow loading workouts.

SARS-CoV-2 risk assessment for a 30-minute car journey

In this paper a numerical methodology for close proximity exposure (<2m) is applied to the analysis of aerosol airborne dispersion and SARS-CoV-2 potential infection risk during short journeys in passenger cars. It consists of a three-dimensional transient Eulerian-Lagrangian numerical model coupled with a recently proposed SARS-CoV-2 emission approach, using the open-source software OpenFOAM. The numerical tool, validated by Particle Image Velocimetry (PIV), is applied to the simulation of aerosol droplets emitted by a contagious subject in a car cabin during a 30-minute journey and to the integrated risk assessment for SARS-CoV-2 for the other passengers. The effects of different geometrical and thermo-fluid-dynamic influence parameters are investigated, showing that both the position of the infected subject and the ventilation system design affect the amount of virus inhaled and the highest-risk position inside the passenger compartment. Calculated infection risk, for susceptible passengers in the car, can reach values up to 59%. © 2022 17th International Conference on Indoor Air Quality and Climate, INDOOR AIR 2022.

Probing environmental and tectonic changes underneath Mexico City with the urban seismic field

The sediments underneath Mexico City have unique mechanical properties that give rise to strong site effects. We investigated temporal changes in the seismic velocity at strong-motion and broadband seismic stations throughout Mexico City, including sites with different geologic characteristics ranging from city center locations situated on lacustrine clay to hillside locations on volcanic bedrock. We used autocorrelations of urban seismic noise, enhanced by waveform clustering, to extract subtle seismic velocity changes by coda wave interferometry. We observed and modeled seasonal, co- and post-seismic changes, as well as a long-term linear trend in seismic velocity. Seasonal variations can be explained by self-consistent models of thermoelastic and poroelastic changes in the subsurface shear wave velocity. Overall, sites on lacustrine clay-rich sediments appear to be more sensitive to seasonal surface temperature changes, whereas sites on alluvial and volcaniclastic sediments and on bedrock are sensitive to precipitation. The 2017 Mw 7.1 Puebla and 2020 Mw 7.4 Oaxaca earthquakes both caused a clear drop in seismic velocity, followed by a time-logarithmic recovery that may still be ongoing for the 2017 event at several sites or that may remain incomplete. The slope of the linear trend in seismic velocity is correlated with the downward vertical displacement of the ground measured by interferometric synthetic aperture radar, suggesting a causative relationship and supporting earlier studies on changes in the resonance frequency of sites in the Mexico City basin due to groundwater extraction. Our findings show how sensitively shallow seismic velocity and, in consequence, site effects react to environmental, tectonic and anthropogenic processes. They also demonstrate that urban strong-motion stations provide useful data for coda wave monitoring given sufficiently high-amplitude urban seismic noise.

Effect of BNT162b2 mRNA COVID-19 vaccine on sperm morphokinetics and DNA integrity: A prospective observational study in Japan

Objective: To assess whether the coronavirus disease 2019 (COVID-19) mRNA vaccine affects sperm morphokinetics using a computer-assisted semen analyzer and other semen parameters using a sperm chromatin structure assay. Method(s): Healthy male volunteers in two Japanese clinics between May 2021 and December 2021 were prospectively analyzed. Participants donated sperm twice, two days apart, in the following phases: before vaccination, 2 weeks after the first vaccine dose, and 2, 4, and 12 weeks after the second dose. Basic sperm parameters, sperm motility characteristics, and the percentage of DNA-damaged sperm were compared among the different phases. Result(s): Ninety-six semen samples from ten volunteers, who were vaccinated with the BNT162b2 mRNA vaccine, were evaluated. There were no significant differences between any phases in basic semen findings and parameters of the sperm chromatin structure assays. Regarding sperm motion characteristics, the average linear velocity, beat-cross frequency, and sperm motility index significantly decreased after the second vaccine dose (P=0.018, P=0.003, and P=0.027, respectively), with no significant differences between any two phases by post-hoc pairwise comparisons. Conclusion(s): After COVID-19 mRNA vaccination, while sperm motion characteristics might fluctuate, no apparent deterioration of basic sperm parameters or sperm DNA integrity was observed. Given the adverse effects of COVID-19 on sperm, our findings suggest that there might be no reason to refrain from vaccination for healthy individuals.Copyright © 2023 Asian Pacific Journal of Reproduction Produced by Wolters Kluwer- Medknow.

Respiratory support for adult patients with COVID-19

The COVID-19 pandemic is creating unique strains on the healthcare system. While only a small percentage of patients require mechanical ventilation and ICU care, the enormous size of the populations affected means that these critical resources may become limited. A number of non-invasive options exist to avert mechanical ventilation and ICU admission. This is a clinical review of these options and their applicability in adult COVID-19 patients. Summary recommendations include: (1) Avoid nebulized therapies. Consider metered dose inhaler alternatives. (2) Provide supplemental oxygen following usual treatment principles for hypoxic respiratory failure. Maintain awareness of the aerosol-generating potential of all devices, including nasal cannulas, simple face masks, and venturi masks. Use non-rebreather masks when possible. Be attentive to aerosol generation and the use of personal protective equipment. (3) High flow nasal oxygen is preferred for patients with higher oxygen support requirements. Non-invasive positive pressure ventilation may be associated with higher risk of nosocomial transmission. If used, measures special precautions should be used reduce aerosol formation. (4) Early intubation/mechanical ventilation may be prudent for patients deemed likely to progress to critical illness, multi-organ failure, or acute respiratory distress syndrome (ARDS).Copyright © 2020 The Authors.

Post-Covid-syndrome and transient microvascular pathology in pulse-waveanalysis - association with Mg/Ca ratio and magnesium therapy-options

Post-COVID-syndromes have a high impact on incapacity for work: a mean of over 100 days has been reported in Germany [1]. Magnesium deficiency is documented as a riskincreasing factor for fatal outcome of acute covid disease [2, 3]. A first case report of post-COVID treatment with hybrid magnesium parenteral/ oral was presented in February 2021 during the Global Magnesium COVID 19 online conference. As of yet, there is no established explanation for post-COVID or long-COVID syndrome as well as there being no established treatment. In recourse to the hypothesis that magnesiumdepletion might favour microvascular early-aging and so favour neuro- degenerative prozesses [4] now preliminary observations of these parameters in post-covid patients in our primary care office result. This is done in connection with long years documentation of pulsewave-analysis (pwv), magnesium and Mg/Caprofiles in patients who suffered covid- disease. Figure 1 shows an over 6-year series of pulse-wave-analyses in a 59-year-old female patient who suffered from post-COVID syndrome. Her augmentation index (AIX) as an indicator of the actual microvascular condition increased from favorable 8% (2020) to highly pathological 39% in the post-COVID disease period - corresponding with the mean value of an 80-year-old person [5]. Another 67-year-old female post-COVID patient recovered clinically very well and quickly with high-dosed magnesium therapy and showed coincident positive decrease of AIX to 4%. Further case reports in the context of magnesium pretests and AIX are presented. Late controlled studies concerning magnesium supplementation and PWV focus on the other parameter - the (macrovascular determined) pulse-wave-velocity (PWV) and found no association of PWV with several months of magnesium supplementation [6]. Therefore, it must be emphasized that all our observations of the last years where not based on PWV but rather focused on AIX as a volatile but more magnesium-dependent parameter. Furthermore, our patients where mostly supplemented over years and not only 24 weeks. Evident is the overall small number of clinically manifesting post-COVID cases among our COVID patients (n= 10 when writing the ) among actually 470 Corona-context treatment cases. We have two working hypotheses for this. I: Persistently high magnesium levels may contrib- ute to reducing the number of post- COVID cases - and II: In the case of post-COVID syndrome, high-dose possibly hybrid magnesium therapy might favorably influence the course of the disease. The Corona pandemic and its microvascular consequences are possibly and unfortunately a non-intended turbo-experiment for microvascular early aging in a great number of undetected magnesium- depletion patients. Facing the burden of disease for individuals - and society as a whole - this justifies not only controlled studies but also the increased attention of medical doctors to the optimal magnesium status of these patients.

Mission Vaccine Suraksha - A Massive COVID 19 Vaccination Drive by Reliance Industries Limited

Introduction: Since the beginning of COVID 19 pandemic, more than 641 million cases and 6.63 million confirmed deaths were reported worldwide. A rapid development of COVID 19 Vaccine was the breakthrough in the prevention and control of COVID 19. India has commenced its vaccination drive from January 16, 2021 and has administered more than 219 crores vaccination to date it its people. On war foot, Reliance Industries Limited also launched its free vaccination coverage program - Mission Vaccine Suraksha for employees, family members, and community by collaborating with local authorities and governments. The organization also provided free vaccination to Kerala, Gujarat, Rajasthan, and Maharashtra besides various other national and regional organisations to speed up the vaccination drive. Methodology: A taskforce including stakeholders form the Medical Services, HR, Procurement, Logistics, transportation, digital systems was formed to oversee, implement, monitor, and evaluate a successful vaccine roll-out drive. The drive included Covishield and Covaxin COVID 19 vaccines. As a single point of contact, Reliance Foundation HN Hospital procured, stored, and transported vaccines to all locations. At par with Govt. protocols, Reliance developed its own workplace COVID vaccination centres (CVCs) at its corporate headquarters and 11 other manufacturing sites in Maharashtra and Gujrat. For Cold chain management, Reliance procured Ice Lined Refrigerators (ILRs), refrigerators, vaccine carriers, icepacks, etc. for each CVC. Dedicated medical and paramedical staffs were recruited and trained to carry out vaccination drive with all the COVID 19 protocols in place. Reliance tied up with multiple hospitals to carry out pan-India vaccination drive. The entire operation was digitally enabled by involving mediums such as Reliance's in-house app JioHealthHub (JHH) that included end-to-end vaccination journey, i.e., from slot booking, CoWIN registration, post-vaccination care, uploading of the certificates, etc. Vaccine inventory was monitored by Reliance's digital system named KiviHealth. A vaccination dashboard was created to track real time vaccination update. Result(s): 40 lakh vaccine doses were provided free of cost to support the nationwide vaccination programme. Till date, 31,63,870 beneficiaries were covered under R-Suraksha under which, 15,94,357 people received their 1st dosage, 13,36,613 received the 2nd dose, and 2,32,900 people have received the precautionary dose. Reliance also commenced vaccination for children aged 12 to 17 years covering 7369 children for 1st dose, 5802 children for 2nd dose. Reliance has achieved 100% compliance for 2 doses of COVID 19 vaccination for its employees and contract workers across manufacturing units. Precautionary dose was administered to 75% of employees and contract workers to date. 25 mild and 3 moderate Adverse Event Following Immunization (AEFI) cases were recorded during vaccination at workplace CVCs, which were managed and sent home. Conclusion(s): Reliance's Mission Vaccine Suraksha has reached to all corners of the country, including people with disabilities, the elderly, homeless, and those in far-flung locations. Reliance faced hurdles in procuring and storing of the vaccines at the beginning of the operation. However, this was tackled effectively with strategic approach. The initiative is still ongoing ensuring maximum precautionary dosage coverage for everyone.

A Sham-Controlled Randomized Trial of Low Intensity Shockwave Therapy for Erectile Dysfunction

INTRODUCTION AND OBJECTIVE: We performed a shamcontrolled, randomized prospective trial in men with ED using an electrohydraulic shockwave device FDA cleared for connective tissue activation and improved blood flow. METHOD(S): This single-blind study was performed in men with ED naive to acoustic wave and shockwave therapy. Patients were randomized to treatment and assigned to active low intensity shockwave therapy (LiSWT) (4 Hz, 0.12 mJ/mm2) or sham treatment, 2:1. Arm 1 consisted of 3 treatments of 5000 shocks every 3 weeks. Arm 2 consisted of 5000, 3000, and 3000 shocks during weeks 1, 2, and 3, respectively, followed by an identical cycle of treatment 3 weeks later. Doppler ultrasound and grayscale imaging with a 15.4 MHz probe were performed under pharmacologic erection at weeks 20 and 32. Subjects completing sham treatment were unblinded and crossed over to the opposite arm for active treatment. Post-treatment end diastolic velocity (EDV) and peak systolic velocity (PSV) were measured, and visual grading scores were used to assess extent of hypoechoic regions in the corpora cavernosa. Data were analyzed by 2-way repeated measures ANOVA with Geisser-Greenhouse correction. Pairwise comparisons were performed to baseline used Dunnett's multiple comparison test. Missing data were imputed by "last observation carried forward". RESULT(S): Although powered for 60, recruitment was limited due to COVID and 36 subjects (22 active, 14 sham) were randomized. Sham treatments showed no significant changes in outcome measures. The number of subjects with improved visual grading scores in the proximal region was consistently higher in active LiSWT vs sham (Arm 1=88.9% vs. 11.1%;Arm 2=40.0% vs. 20.0%, respectively) with statistical significance in Arm 1 at weeks 20 (p=0.005) and 32 (p=0.001). Sham subjects rolled over to active LiSWT also had improved grayscale ratings (Arm 1=33.3% vs. 11.1%;Arm 2=40.0% vs. 20.0%). After LiSWT, greater numbers of patients had higher PSV, lower EDV, or no worsening of blood flow parameters relative to baseline. Decrease in EDV was statistically significant in active treatment Arm 2 at Week 32 (p=0.003). Mean IIEF-EF scores were nominally higher in subjects in active treatment who had improved visual grading scores vs those with no improvement. Adverse events were transient. CONCLUSION(S): Flaccid penile LiSWT appears to be safe and efficacious for treating ED based on statistically significant changes from baseline between sham and active treatments in primary outcome measures.

A New Big Data Architecture for Analysis: The Challenges on Social Media

The streams of social media big data are now becoming an important issue. But the analytics method and tools for this data may not be able to find the useful information from this massive amount of data. The question then becomes: how do we create a high-performance platform and a method to efficiently analyse social networks' big data;how to develop a suitable mining algorithm for finding useful information from social media big data. In this work, we propose a new hierarchical big data analysis for understanding human interaction, and we present a new method to measure the useful tweets of Twitter users based on the three factors of tweet texts. Finally, we use this test implementation score, in order to detect useful and classification tweets by interested degree.

Stability and WBE biomarkers possibility of 17 antiviral drugs in sewage and gravity sewers.

Wastewater-based epidemiology (WBE) is a promising technique for monitoring the rapidly increasing use of antiviral drugs during the COVID-19 pandemic. It is essential to evaluate the in-sewer stability of antiviral drugs in order to determine appropriate biomarkers. This study developed an analytical method for quantification of 17 typical antiviral drugs, and investigated the stability of target compounds in sewer through 4 laboratory-scale gravity sewer reactors. Nine antiviral drugs (lamivudine, acyclovir, amantadine, favipiravir, nevirapine, oseltamivir, ganciclovir, emtricitabine and telbivudine) were observed to be stable and recommended as appropriate biomarkers for WBE. As for the other 8 unstable drugs (abacavir, arbidol, ribavirin, zidovudine, ritonavir, lopinavir, remdesivir and efavirenz), their attenuation was driven by adsorption, biodegradation and diffusion. Moreover, reaction kinetics revealed that the effects of sediments and biofilms were regarded to be independent in gravity sewers, and the rate constants of removal by biofilms was directly proportional to the ratio of surface area against wastewater volume. The study highlighted the potential importance of flow velocity for compound stability, since an increased flow velocity significantly accelerated the removal of unstable biomarkers. In addition, a framework for graded evaluation of biomarker stability was proposed to provide reference for researchers to select suitable WBE biomarkers. Compared with current classification method, this framework considered the influences of residence time and different removal mechanisms, which additionally screened four antiviral drugs as viable WBE biomarkers. This is the first study to report the stability of antiviral drugs in gravity sewers.

A normative blood velocity model in the exchange microvessels for discriminating health from disease: Healthy controls versus COVID-19 cases.

A usual practice in medicine is to search for "biomarkers" which are measurable quantities of a normal or abnormal biological process. Biomarkers can be biochemical or physical quantities of the body and although commonly used statistically in clinical settings, it is not usual for them to be connected to basic physiological models or equations. In this work, a normative blood velocity model framework for the exchange microvessels was introduced, combining the velocity-diffusion (V-J) equation and statistics, in order to define the normative range (NR) and normative area (NA) diagrams for discriminating normal (normemic) from abnormal (hyperemic or underemic) states, taking into account the microvessel diameter D. This is different from the usual statistical processing since there is a basis on the well-known physiological principle of the flow diffusion equation. The discriminative power of the average axial velocity model was successfully tested using a group of healthy individuals (Control Group) and a group of post COVID-19 patients (COVID-19 Group).

Commencing Novel Therapies for Adult Sma Patients: Experience from a Hybrid Clinic

Spinal muscular atrophy (SMA) is a progressive neuromuscular disorder that affect both adults and children. Two novel therapies were approved for patients in England by NICE (Nusinersen via Management Access Agreement (MAA) and Risdiplam via Early Access to Medicine scheme (EAMS)). Setting up baseline assessments, designing new pathways, acquiring personnel and resources have been challenging. We present a pathway analysis of the new clinic set-up, process of patient choice, risk minimisation in intro- ducing the two novel therapies, and the impact therapies have had on adult cohort of SMA patients. Total of 58 patients included (31 had type 2 SMA and 27 had type 3[only 11/27 were ambulant]. The average age of patients with type 2 and 3 SMA was 25 and 33 respectively. 19 patients chose risdiplam (oral) and 22 are on nusinersen (intra thecal). We analysed factors that govern patients' treatment decisions. We report factors that helped early success in our hybrid clinic set-up. Set criteria on each scheme;but potential side effects, information availability, route of administration (mainly previous spinal surgery), speed at treatment initiation but not COVID directed many patients' treatment decisions. A battery of outcome measures were analysed to establish treatment impact at 12 months.

Temporal strategies and firms' speedy responses to COVID-19

Countries around the world have suffered widespread disruption from the COVID-19 pandemic. Tens of millions have been infected and economies have suffered severe downturns. Firms in Asia quickly took up central roles in developing novel responses to the pandemic. The COVID-19 pandemic has created pressure for the refinement and implementation of temporal strategies to speed helpful therapies through testing and safely on to market. Facing this speed challenge, healthcare firms in Asia have responded with various alternative strategies to accelerate therapy development, testing, and distribution.
