A Year of Deaths Due to or With COVID-19 Under Universal Postmortem Testing in San Francisco.

ABSTRACT: The Health Officer of the City and County of San Francisco, California, issued the order that all decedents were required to have a documented COVID-19 test effective from June 2020 to June 2021. The justification for the requirement was that complete data on COVID-19 status at the time of death were needed to help protect first responders and funeral home workers, identify missed cases, and characterize the places of death for otherwise unknown COVID-19 cases. To fill the gap in COVID-19 testing for all decedents, particularly among persons dying outside of hospitals, a specialized Decedent Testing Unit was created along with an increased capacity of the Office of the Chief Medical Examiner. From July 1, 2020, to June 30, 2021, the Decedent Testing Unit and Office of the Chief Medical Examiner provided postmortem testing results for 2776 decedents. Of these, 80 tested positive for COVID-19 for a positivity rate of 2.97%. The largest number of COVID-19-positive specimens were collected from persons who died at home (n = 37, 46.3%), followed by those who died in hospice (n = 20, 25.0%), other places outside of homes or facilities (n = 8, 10.0%), and in skilled nursing or long-term care facilities (n = 7, 8.8%). Follow-up of California death records found that 17 of these 80 cases (21.3%) had COVID-19 listed as one of the causes of death, 22 (27.5%) mentioned COVID-19 under "other conditions," and 41 (51.3%) made no mention of COVID-19. In the context of providing the COVID-19 status of decedents not otherwise known to have infection, our data help gauge the likelihood of missing deaths due to or with COVID-19 and inform future public health decisions on whether to require universal postmortem testing with COVID-19 resurgences or with new deadly epidemics.

[Organ donation-Not only a responsibility of intensive care medicine]. / Organspende ­ Nicht nur eine intensivmedizinische Aufgabe.

In 2019 a total of 756 people died in Germany while registered on the waiting list for an organ transplantation. With 10.8 organ donors/million inhabitants in 2019, Germany belongs to the bottom group in the Eurotransplant foundation as well as worldwide. All political attempts to increase the number of organ donations have so far been unsuccessful. Furthermore, the pandemic triggered by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) led to a further decline in organ donations. Critical care physicians play an important role in the identification of potential doners and are also the main point of contact for relatives; however, multiple uncertainties exist regarding the process of organ donation not only in discussions in the media and society but also among physicians involved in intensive care medicine. Many assumptions and hypotheses, which have been associated with the low number of donors, lack scientific evidence and are discussed in this article.

Convalescent plasma for the treatment of patients with severe coronavirus disease 2019: A preliminary report.

BACKGROUND: The role of convalescent plasma therapy for patients with coronavirus disease 2019 (COVID-19) is unclear. METHODS: We retrospectively compared outcomes in a cohort of critical COVID-19 patients who received standard care (SC Group) and those who, in addition, received convalescent plasma (CP Group). RESULTS: In total, 40 patients were included in each group. The median patient age was 53.5 years (interquartile range [IQR] 42-60.5), and the majority of patients required invasive ventilation (69, 86.2%). Plasma was harvested from donors after a median of 37 days (IQR 31-46) from the first positive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR) result and 26 days (IQR 21-32) after documented viral clearance; it was administered after a median of 10 days (IQR 9-10) from the onset of symptoms and 2.5 days (IQR 2-4) from admission to intensive care unit. The primary endpoint of improvement in respiratory support status within 28 days was achieved in 26 patients (65%) in the SC Group and 31 patients (77.5%) in the CP Group (p = .32). The 28-day all-cause mortality (12.5% vs. 2.5%; p = .22) and viral clearance (65% vs. 55%; p = .49) were not significantly different between the two groups. Convalescent plasma was not significantly associated with the primary endpoint (adjusted hazard ratio 0.87; 95% confidence interval 0.51-1.49; p = .62). Adverse events were balanced between the two study groups. CONCLUSION: In severe COVID-19, convalescent plasma therapy was not associated with clinical benefits. Randomized trials are required to confirm our findings.

Coronavirus disease 2019 in solid organ transplant recipients in the setting of proactive screening and contact tracing of Qatar.

BACKGROUND: Clinical data on Coronavirus Disease 2019 (COVID-19) in solid organ transplant (SOT) recipients are limited. We herein report the initial clinical experience with COVID-19 in SOT recipients in Qatar. METHODS: All SOT recipients with laboratory-confirmed COVID-19 up to May 23, 2020 were included. Demographic and clinical data were extracted retrospectively from the hospital's electronic health records. Categorical data are presented as frequency and percentages, while continuous variables are summarized as medians and ranges. RESULTS: Twenty-four SOT recipients with COVID-19 were identified (kidney 16, liver 6, heart 1, and liver and kidney 1). Organ transplantation preceded COVID-19 by a median of 60 months (range 1.7-184). The median age was 57 years (range 24-72), and 9 (37.5%) transplant recipients were females. Five (21%) asymptomatic patients were diagnosed through proactive screening. For the rest, fever (15/19) and cough (13/19) were the most frequent presenting symptoms. Five (20.8%) patients required invasive mechanical ventilation in the intensive care unit (ICU). Eleven (46%) patients developed acute kidney injury, including three in association with drug-drug interactions involving investigational COVID-19 therapies. Maintenance immunosuppressive therapy was modified in 18 (75%) patients, but systemic corticosteroids were not discontinued in any. After a median follow-up of 226 days (26-272), 20 (83.3%) patients had been discharged home, 2 (8.3%) were still hospitalized, 1 (4.2%) was still in the ICU, and 1 (4.2%) had died. CONCLUSIONS: Our results suggest that asymptomatic COVID-19 is possible in SOT recipients and that overall outcomes are not uniformly worse than those in the general population. The results require confirmation in large, international cohorts.

The first consecutive 5000 patients with Coronavirus Disease 2019 from Qatar; a nation-wide cohort study.

BACKGROUND: There are limited data on Coronavirus Disease 2019 (COVID-19) outcomes at a national level, and none after 60 days of follow up. The aim of this study was to describe national, 60-day all-cause mortality associated with COVID-19, and to identify risk factors associated with admission to an intensive care unit (ICU). METHODS: This was a retrospective cohort study including the first consecutive 5000 patients with COVID-19 in Qatar who completed 60 days of follow up by June 17, 2020. The primary outcome was all-cause mortality at 60 days after COVID-19 diagnosis. In addition, we explored risk factors for admission to ICU. RESULTS: Included patients were diagnosed with COVID-19 between February 28 and April 17, 2020. The majority (4436, 88.7%) were males and the median age was 35 years [interquartile range (IQR) 28-43]. By 60 days after COVID-19 diagnosis, 14 patients (0.28%) had died, 10 (0.2%) were still in hospital, and two (0.04%) were still in ICU. Fatal COVID-19 cases had a median age of 59.5 years (IQR 55.8-68), and were mostly males (13, 92.9%). All included pregnant women (26, 0.5%), children (131, 2.6%), and healthcare workers (135, 2.7%) were alive and not hospitalized at the end of follow up. A total of 1424 patients (28.5%) required hospitalization, out of which 108 (7.6%) were admitted to ICU. Most frequent co-morbidities in hospitalized adults were diabetes (23.2%), and hypertension (20.7%). Multivariable logistic regression showed that older age [adjusted odds ratio (aOR) 1.041, 95% confidence interval (CI) 1.022-1.061 per year increase; P < 0.001], male sex (aOR 4.375, 95% CI 1.964-9.744; P < 0.001), diabetes (aOR 1.698, 95% CI 1.050-2.746; P 0.031), chronic kidney disease (aOR 3.590, 95% CI 1.596-8.079, P 0.002), and higher BMI (aOR 1.067, 95% CI 1.027-1.108 per unit increase; P 0.001), were all independently associated with increased risk of ICU admission. CONCLUSIONS: In a relatively younger national cohort with a low co-morbidity burden, COVID-19 was associated with low all-cause mortality. Independent risk factors for ICU admission included older age, male sex, higher BMI, and co-existing diabetes or chronic kidney disease.

[Outpatient treatment of acute injuries of upper extremities with axillary plexus anesthesia in the emergency department-Is that possible without continuous anesthesia attendance?] / Ambulante Versorgung akuter Verletzungen der oberen Extremität in der Notfallambulanz in axillärer Plexusanästhesie ­ Ist das ohne durchgehende Anästhesiebegleitung machbar?

BACKGROUND: The incorporation into the routine operating procedure of patients with small but acute hand and forearm injuries requiring surgery who present in the emergency admission department, represents a challenge due to limited resources. The prompt treatment in the emergency admission department represents an alternative. This article retrospectively reports the authors' experiences with a treatment algorithm in which emergency patients were treated by ultrasound-guided axillary brachial plexus blocks (ABPB) and surgery carried out in the emergency department without further anesthesia attendance. METHODS: Patients were preselected by the surgeon if they were suitable for a standardized treatment without anesthesia attendance during surgery. If there were no anesthesiological or surgical contraindications patients received an ABPB in the holding area of the operating room (OR) under standard monitoring. Blocks were performed as a multi-injection, ultrasound-guided technique which is anatomically described in detail. Patients >60 kg received a total volume of 30 ml of a mixture of 10 ml 1% ropivacaine (100 mg) and 20 ml 2% prilocaine (400 mg). Patients <60 kg received the same mixture with a reduced volume of 25 ml corresponding to 82.5 mg ropivacaine and 332.5 mg prilocaine. After controlling for block success patients were admitted to the emergency department and the surgical procedure was carried out under supervision by the surgeon without further anesthesia attendance. At discharge patients were explicitly instructed that in the case of any complications or a continuation of the block for more than 24 h they should contact the emergency department. RESULTS: Between January 2013 and November 2017 a total of 566 patients (46.4 years, range 11-88 years, 174.9 cm, range 140-211cm, 80.8 kg, range 42-178kg, ASA 1/2/3, 190/338/38, respectively) were treated according to a standardized protocol. The ABPBs were performed by 74 anesthetists. In 5% of the patients the initial block was incomplete and rescue blocks were performed with a maximum of 2­3ml 1% prilocaine per corresponding nerve. After completion the block was ensured and all patients underwent surgery without further analgesics or local anesthetic infiltration by the surgeon. Complications related to the ABPB and readmissions were not observed. CONCLUSION: It could be demonstrated that minor surgery could be carried out safely and effectively with a defined algorithm using ABPB in selected patients outside the OR without permanent anesthesia attendance: however, indispensable prerequisites for such procedures are careful patient selection, patient compliance, the safe and effective performance of the ABPB and reliable agreement with the surgeon.

Nineteen Years of Consistently Positive and Strong Female Mate Preferences despite Individual Variation.

Sexual selection driven by mate choice has generated some of the most astounding diversity in nature, suggesting that population-level preferences should be strong and consistent over many generations. On the other hand, mating preferences are among the least repeatable components of an individual animal's phenotype, suggesting that consistency should be low across an animal's lifetime. Despite decades of intensive study of sexual selection, there is almost no information about the strength and consistency of preferences across many years. In this study, we present the results of more than 5,000 mate choice tests with a species of wild frog conducted over 19 consecutive years. Results show that preferences are positive and strong and vary little across years. This consistency occurs despite the fact that there are substantial differences among females in their strength of preference. We also suggest that mate preferences in populations that are primarily the result of sensory exploitation might be more stable over time than preferences that are primarily involved in assessing male quality.

Discovery of a nanomolar inhibitor of the human glyoxalase-I enzyme using structure-based poly-pharmacophore modelling and molecular docking.

The glyoxalase-I (GLO-I) enzyme, which is the initial enzyme of the glyoxalase system that is responsible for the detoxification of cytotoxic α-ketoaldehydes, such as methylglyoxal, has been approved as a valid target in cancer therapy. Overexpression of GLO-I has been observed in several types of carcinomas, including breast, colorectal, prostate, and bladder cancer. In this work we aimed to identify potential GLO-I inhibitors via employing different structure-based drug design techniques including structure-based poly-pharmacophore modelling, virtual screening, and molecular docking. Poly-pharmacophore modelling was applied in this study in order to thoroughly explore the binding site of the target enzyme, thereby, revealing hits that could bind in a nonconventional way which can pave the way for designing more potent and selective ligands with novel chemotypes. The modelling phase has resulted in the selection of 31 compounds that were biologically evaluated against human GLO-I enzyme. Among the tested set, seven compounds showed excellent inhibitory activities with IC50 values ranging from 0.34 to 30.57 µM. The most active compound (ST018515) showed an IC50 of 0.34 ± 0.03 µM, which, compared to reported GLO-I inhibitors, can be considered a potent inhibitor, making it a good candidate for further optimization towards designing more potent GLO-I inhibitors.

Investigating pathogen burden in relation to a cumulative deficits index in a representative sample of US adults.

Pathogen burden is a construct developed to assess the cumulative effects of multiple, persistent pathogens on morbidity and mortality. Despite the likely biological wear and tear on multiple body systems caused by persistent infections, few studies have examined the impact of total pathogen burden on such outcomes and specifically on preclinical markers of dysfunction. Using data from two waves of the National Health and Nutrition Examination Survey, we compared three alternative methods for measuring pathogen burden, composed of mainly persistent viral infections, using a cumulative deficits index (CDI) as an outcome: single pathogen associations, a pathogen burden summary score and latent class analyses. We found significant heterogeneity in the distribution of the CDI by age, sex, race/ethnicity and education. There was an association between pathogen burden and the CDI by all three metrics. The latent class classification of pathogen burden showed particularly strong associations with the CDI; these associations remained after controlling for age, sex, body mass index, smoking, race/ethnicity and education. Our results suggest that pathogen burden may influence early clinical indicators of poor health as measured by the CDI. Our results are salient since we were able to detect these associations in a relatively young population. These findings suggest that reducing pathogen burden and the specific pathogens that drive the CDI may provide a target for preventing the early development of age-related physiological changes.

[Anesthesia management in microsurgical reconstructions]. / Anästhesiologisches Management bei mikrochirurgischen Rekonstruktionen.

Microsurgical procedures for construction of anastomoses present new challenges for anesthetists in the perioperative setting. Despite their increasing importance, so far no perioperative management guidelines for these patients existed. Anesthetists can influence the success of surgery (e. g. successful perfusion of a flap) via an optimal preoperative, intraoperative and postoperative approach. Patients should be carefully evaluated preoperatively for increased risks to avoid poor postoperative outcomes. Perioperatively, the choice of anesthetic procedure as well as the management of fluid infusion, blood glucose, temperature and blood transfusion are of great importance. Adequate analgesia as well as strict control should be performed as soon as possible postoperatively, preferably in a surveillance unit to detect and treat any complications as early as possible.

[Anesthesiological approach for patients with spinal cord injuries]. / Anästhesiologisches Vorgehen bei Patienten mit spinalem Querschnitt.

Spinal cord injuries (SCI) are serious medical conditions, which are associated with severe and potentially fatal risks and complications depending on the location and extent of injury. Traffic accidents, falls and recreational activities are the leading causes for traumatic SCI (TSCI) worldwide whereas non-traumatic spinal cord injuries (NTSCI) are mostly due to tumors and congenital diseases. As chronification of the injuries progresses other organ systems are affected including anatomical changes, the respiratory and cardiovascular systems and endocrinological pathways. All these effects have to be considered in the anesthesiological management of patients with SCI. Autonomic dysreflexia (AD) is the most dangerous and life-threatening complication in patients with chronic SCI above T6 that results from an overstimulation of sympathetic reflex circuits in the upper thoracic spine and can be fatal. This article summarizes the specific pathophysiology of SCI and how AD can be avoided as well as also providing anesthetists with strategies for perioperative and intensive care management of patients with SCI.

Harmonic calls and indifferent females: no preference for human consonance in an anuran.

The human music faculty might have evolved from rudimentary components that occur in non-human animals. The evolutionary history of these rudimentary perceptual features is not well understood and rarely extends beyond a consideration of vertebrates that possess a cochlea. One such antecedent is a preferential response to what humans perceive as consonant harmonic sounds, which are common in many animal vocal repertoires. We tested the phonotactic response of female túngara frogs (Physalaemus pustulosus) to variations in the frequency ratios of their harmonically structured mating call to determine whether frequency ratio influences attraction to acoustic stimuli in this vertebrate that lacks a cochlea. We found that the ratio of frequencies present in acoustic stimuli did not influence female response. Instead, the amount of inner ear stimulation predicted female preference behaviour. We conclude that the harmonic relationships that characterize the vocalizations of these frogs did not evolve in response to a preference for frequency intervals with low-integer ratios. Instead, the presence of harmonics in their mating call, and perhaps in the vocalizations of many other animals, is more likely due to the biomechanics of sound production rather than any preference for 'more musical' sounds.

Maternal skepticism regarding children's vaccination in Jordan: Investigating the knowledge, attitude, and adherence.

Vaccination is critical to every responsible healthcare system, yielding several health and economic benefits. However, skepticism is a major challenge to vaccination adherence among parents globally. Mothers are primary decision-makers on children's vaccination; therefore, this study aims to assess maternal knowledge, attitudes, and adherence to children's routine vaccination in Jordan, identify the main sources of related information, and explore the awareness and hesitancy related to elective vaccination, which is not incorporated into the national vaccination program (e.g., varicella, flu, meningitis, and meningococcal vaccines). A descriptive, cross-sectional design was conducted to collect data from 533 Jordanian mothers between August and November 2023. Participant mothers completed an online self-administered questionnaire comprising demographics, knowledge, attitudes, and adherence to children's vaccination. The surveyed mothers in general exhibited high levels of knowledge, attitudes, and adherence concerning children's vaccination and a relatively moderate level of adherence concerning elective vaccines. The mothers' perspectives of reluctance towards elective vaccines were explored. The primary healthcare center and physicians were the most prevalent sources of mothers' vaccine-related information. Future efforts should implement tailored health education campaigns that address specific knowledge gaps, such as misconceptions about contraindications and side effects, promote awareness about elective vaccines, and engage healthcare providers to facilitate informed decision-making among Jordanian mothers and improve children's vaccination coverage.

Incidence of Unplanned Readmissions After One-Day Surgery Discharge Among Pediatric Patients: A Retrospective Study From a Tertiary Care Hospital in Saudi Arabia.

Introduction The prevalence of one-day surgery (also known as same-day surgery or outpatient surgery) has been increasing recently among patients and physicians in many countries due to its benefits. The main benefits of one-day surgery are that the patient is not planned to stay overnight before the surgery and can be discharged on the same day of the surgery. The lower cost to the health system can make these surgeries more favorable for both sides. However, unplanned readmission after such surgeries can happen and this has broad implications for patients, their families, and the healthcare system. Therefore, this study primarily aims to identify the incidence of unexpected hospital readmissions following one-day surgery after discharge among children. The study also aims to identify any significant variables that can be identified with the cases of readmissions to allow for further investigations in future studies Methods This study was done at King Abdullah Specialist Children's Hospital in Riyadh, Saudi Arabia. The target population included all pediatric patients who underwent one-day surgeries and were admitted within one week of their discharge from 2017 to 2023 through outpatient clinics and the emergency department. Results The study sample size was 403 patients, with male patients accounting for 241 surgeries (59.8%), and female patients accounting for 162 surgeries (40.1%). The most common American Society of Anesthesiologists (ASA) classification was II, accounting for 169 cases (41.9%). Toddlers and preschoolers (aged 1-6 years) were the age groups with the highest number of patients (n=252, 62.5% combined). Elective surgeries accounted for 382 cases (94.7%). The specialty with the highest number of surgeries was ear, nose, and throat with 284 cases (70.4%) with tonsillectomy with adenoidectomy being the most common surgery with 234 cases (58%). The most common reasons for unplanned readmission were poor oral intake (n=146, 36.2%) and bleeding (n=131, 32.5%). The most common day of readmission was the seventh day in five surgical specialties (45.4%). Conclusion Over the past seven years, 403 patients were readmitted within one week after their one-day surgery at King Abdullah Specialist Children's Hospital. Such a situation may cause dissatisfaction with the medical care that the patients were given and eventually may build an untrusted relationship between the patient and the physician. Future investigations should be established to lower such a condition and develop prevention methods to lower its prevalence.

Intra-biliary hydatid cyst rupture: A rare case report with superinfection.

Key Clinical Message: Hydatid cysts, primarily found in the liver (70%), are caused by parasitic infections and can lead to severe complications such as cyst rupture. This case report describes a unique instance of a hydatid liver cyst occupying the right lobe with a communicating part with the biliary tree that ruptured showing a concurrent superinfection. Abstract: Hydatid cysts are a clinical pathology resulting from parasitic infections. They may occur in different organs of the body. However, these are mostly found in the liver (70%). This can cause significant complications including cyst rupture. Several case reports have described various hydatid cyst ruptures; however, only a few have reported an intra-biliary hydatid cyst rupture. A 24-year-old male patient presented with right upper quadrant pain, jaundice, dark urine, and pale stool. Imaging studies, including Magnetic resonance cholangiopancreatography (MRCP) and computed tomography (CT), revealed a beavertail liver, cystobiliary communication and intrahepatic biliary tree-ruptured hydatid cysts. The cyst was in the right liver lobe, which is the most common site for hydatid cysts. Surgical intervention involving laparoscopic de-roofing and cyst removal resulted in a smooth recovery without complications. Several case reports have described various hydatid cyst ruptures; however, only a few have reported originally placed intra-biliary hydatid cyst ruptures. This case report describes a unique instance of a hydatid liver cyst occupying the right lobe with a communicating part with the biliary tree that ruptured showing a concurrent superinfection.

Incidence and Risk Factors of Developing Post-operative Delirium Among Elderly Patients in a Tertiary Care Hospital: A Retrospective Chart Review.

Introduction Delirium is an acute and fluctuating decline in attention and cognition caused by reversible neural disruption. Post-operative delirium (POD) may happen 10 minutes after anesthesia administration up to discharge. POD has been associated with increased days of mechanical ventilation, increased patients' functional decline, prolonged intensive care unit (ICU) stay, and prolonged hospital length of stay, which can lead to nosocomial complications, further investigations, and increased treatment costs. In this study, we aim to determine the prevalence of POD and identify demographic or surgical variables associated with POD. Materials and methods This retrospective cross-sectional study was conducted at the National Guard Health Affairs Hospital (NGHA), a teaching tertiary care center in Riyadh, Kingdom of Saudi Arabia. The study included all patients older than 65 who developed POD from January 2017 to January 2023 and a control group of the same time window. The data were analyzed using custom Python code. Results The study included 108 patients, 72 of whom were male patients. General anesthesia was most used compared to other anesthesia techniques (79.630%). Patients with hypertension (HTN) and diabetes mellitus (DM) each account for 75 cases. Elective surgeries account for 86.111% of cases. Our analysis showed a significant association between POD and advanced age, male gender, DM, HTN, congestive heart failure (CHF), and chronic kidney disease (CKD).  Conclusion With our study, we hope to aid the process of better understanding POD to help healthcare providers identify high-risk patients, implement preventative measures, and enhance patient safety and satisfaction.

[Intensive care management of acute diseases of the aorta]. / Intensivmedizinisches Management akuter Aortenerkrankungen.

Acute aortic diseases represent a group of complex severe and often fatal medical conditions. Although they are significantly rarer than cardiac or thromboembolic events, they are an important differential diagnosis to be ruled out, e.g., in the clinical work-up of acute chest pain.Treatment, especially surgical interventions, depends on the progression, extent and size of the pathology and whenever possible should be performed in specialized centers with the appropriate experience.Intensive care monitoring is advisable as a range of peracute complications can occur even in initially stable patients. Depending on the clinical presentation and affected structures, a number of severe complications need to be anticipated by critical care physicians. Additionally, a notable symptom is severe and refractory hypertension, especially in the acute phase. This article provides a summary of the most frequent clinical pictures and corresponding treatment options. Furthermore, the principles of initial patient stabilization and treatment as well as the perioperative management of complex surgical procedures on the aorta are discussed.

Fungemia Due to Saprochaete capitata in a Non-Neutropenic Critically Ill Patient.

Saprochaete capitata is an uncommon yeast species; its impact on non-neutropenic patients appears to be on the rise. We describe a case of S. capitata fungemia in a critically ill end-stage kidney disease (ESKD) patient on peritoneal dialysis. The patient presented with mesenteric ischemia and underwent several laparotomies during hospitalization. His hospital stay was complicated as fungemia developed and spread to multiple sites, which resulted in severe complications and ultimately led to fatal outcomes. S. capitata's diagnostic delay is a concern, but matrix-assisted laser desorption/Ionization time-of-flight (MALDI-TOF) mass spectrometry may help provide accurate identification. Our case highlights the need for prompt diagnosis and tailored antifungal therapy, especially when managing this challenging infection in immunocompromised patients.

Desire for Body Contouring Surgery after Bariatric Surgery: A Nationwide Cross-sectional Study in Saudi Arabia.

Background: The obesity pandemic in Saudi Arabia has led to a high demand for bariatric surgery (BS). Post-BS patients experience rapid and massive weight loss, with most patients experiencing redundant skin, leading to a desire for body contouring surgery (BCS). Methods: A cross-sectional study was conducted from September 2022 to May 2023 among patients who underwent BS in Saudi Arabia, using an online self-administered questionnaire. The questionnaire comprised sociodemographic data, weight, and BS-related questions, and the post-BS appearance questionnaire assessed the desire for BCS, excess skin satisfaction, and overall appearance. Results: A total of 410 of the patients electively enrolled. The mean perceived satisfaction of post-BS patients with the body's excess skin was rated as 4.28 ±â€…1.69 out of 7 points. The overall desire for BCS among the post-BS population was equal to a collective mean desire of 2.10 ±â€…0.92 out of 4 points. The desired body sites for BCS were focused on the abdomen/waist, followed by the lower back, then upper arms, buttocks, and thighs. Only 25.1% of the patients fulfilled their desires and recently underwent BCS. Conclusions: The study highlights the importance of incorporating plastic and reconstructive surgery as an integral part of the multidisciplinary approach to morbidly obese patients after BS and the need for national guidelines on the referral pathway for post-BS BCS.

An Overview of the History, Pathophysiology, and Pharmacological Interventions of Multiple Sclerosis.

Multiple sclerosis (MS) is an immune-inflammatory disease that attacks and damages myelinated axons in the central nervous system (CNS) and causes nontraumatic neurological impairment in young people. Historically, Lidwina of Schiedam documented the first MS case. After that, Augustus d'Este wrote for years about how his MS symptoms worsened. Age, sex, genetics, environment, smoking, injuries, and infections, including herpes simplex and rabies, are risk factors for MS. According to epidemiology, the average age of onset is between 20 and 40 years. MS is more prevalent in women and is common in Europe and America. As diagnostic methods and criteria change, people with MS may be discovered at earlier and earlier stages of the disease. MS therapy has advanced dramatically due to breakthroughs in our knowledge of the disease's etiology and progression. Therefore, the efficacy and risk of treatment medications increased exponentially. Management goals include reducing lesion activity and avoiding secondary progression. Current treatment approaches focus on managing acute episodes, relieving symptoms, and reducing biological activity. Disease-modifying drugs such as fingolimod, interferon-beta, natalizumab, and dimethyl fumarate are the most widely used treatments for MS. For proof of the efficacy and safety of these medications, investigations in the real world are necessary.
