QUALITY ISSUE
The emergence of coronavirus disease of 2019 (COVID-19) highlights the necessity of rapidly identifying and isolating potentially infected individuals. Evaluating this preparedness requires an assessment of the full clinical system, from intake to isolation.
INITIAL ASSESSMENT
Unannounced Standardized Patients (USPs) present a nimble, sensitive methodology for assessing this readiness.
CHOICE OF SOLUTION
Pilot the USP methodology, which employs an actor trained to present as a standardized, incognito potentially infected patient, to assess clinical readiness for potential COVID-19 patients at an urban, community safety-net clinic.
IMPLEMENTATION
The USP was trained to present at each team's front desk with the complaint of feeling unwell (reporting a fever of 101 degrees Fahrenheit in the past 24 hours) and exposure to a roommate recently returned from Beijing. The USP was trained to complete a behaviorally anchored assessment of the care she received from the clinical system.
EVALUATION
There was clear variation in care USPs received; some frontline clerical staff followed best practices; others did not. Signage and information on disease spread prevention publicly available was inconsistent. Qualitative comments shared by the USPs and those gathered during group debrief reinforced the experiences of the USPs and hospital leadership.
LESSONS LEARNED
USPs revealed significant variation in care practices within a clinical system. Utilization of this assessment methodology can provide just-in-time clinical information about readiness and safety practices, particularly during emerging outbreaks. USPs will prove especially powerful as clinicians and systems return to outpatient visits while remaining vigilant about potentially infected individuals.

Exploring the role of temperature and other environmental factors in West Nile virus incidence and prediction in California counties from 2017-2022 using a zero-inflated model.
West Nile virus (WNV) is the most common mosquito-borne disease in the United States, resulting in hundreds of reported cases yearly in California alone. The transmission cycle occurs mostly in birds and mosquitoes, making meteorological conditions, such as temperature, especially important to transmission characteristics. Given that future increases in temperature are all but inevitable due to worldwide climate change, determining associations between temperature and WNV incidence in humans, as well as making predictions on future cases, are important to public health agencies in California. Using surveillance data from the California Department of Public Health (CDPH), meteorological data from the National Oceanic and Atmospheric Administration (NOAA), and vector and host data from VectorSurv, we created GEE autoregressive and zero-inflated regression models to determine the role of temperature and other environmental factors in WNV incidence and predictions. An increase in temperature was found to be associated with an increase in incidence in 11 high-burden Californian counties between 2017-2022 (IRR = 1.06), holding location, time of year, and rainfall constant. A hypothetical increase of two degrees Fahrenheit-predicted for California by 2040-would have resulted in upwards of 20 excess cases per year during our study period. Using 2017-2021 as a training set, meteorological and host/vector data were able to closely predict 2022 incidence, though the models did overestimate the peak number of cases. The zero-inflated model closely predicted the low number of cases in winter months but performed worse than the GEE model during high-transmission periods. These findings suggests that climate change will, and may be already, altering transmission dynamics and incidence of WNV in California, and provides tools to help predict incidence into the future.

BACKGROUND
Febrile seizures occur in about 2 to 4 percent of all children, approximately one third of whom will have recurrent febrile seizures. Little is known about predictors of recurrence.
METHODS
In this prospective study, we identified 347 children (1 month to 10 years of age) who presented with a first febrile seizure at one of four pediatric emergency departments. Information about these children was collected from medical records and interviews with the parents, and the children were followed for a median of 20 months to ascertain whether febrile seizures recurred.
RESULTS
Recurrent febrile seizures occurred in 94 of the 347 children (27 percent) with a cumulative risk of 25 percent at one year and 30 percent at two years. The duration of fever before the initial seizure was associated with the risk of recurrence at one year: for fever lasting less than 1 hour, the risk of recurrence was 44 percent; for fever lasting 1 to 24 hours, 23 percent; and for fever lasting more than 24 hours, 13 percent (P less than 0.001). With each degree of increase in temperature (in degrees Fahrenheit), from 101 degrees F (38.3 degrees C) to greater than or equal to 105 degrees F (40.6 degrees C), the risk of recurrence at one year declined, from 35 percent to 30, 26, 20, and 13 percent (P for trend = 0.024). An age of less than 18 months and a family history of febrile seizures were also associated with an increased risk of recurrence. A family history of epilepsy, complex febrile seizures, and neurodevelopmental abnormalities did not increase the risk of recurrent febrile seizures.
CONCLUSIONS
A shorter duration of fever before the initial febrile seizure and a lower temperature are associated with an increased risk of recurrence in children who have febrile seizures.

BACKGROUND
Pancreatic pseudocyst is a very common benign cystic lesion of the pancreas. It develops in 5-15% of patients with peri-pancreatic fluid collection following acute pancreatitis. Collection usually occurs within the lesser sac of the omentum (near the pancreatic head and body region). But in 20-22% cases, that may be extra-pancreatic like in the mediastinum, pleura, in the peritoneal cavity including the pelvis. The pancreatic pseudocyst typically contains brownish fluid with necrotic tissue sludge which may get infected giving rise to infected pseudocyst or pancreatic abscess. The present case is an unusual condition of a young alcoholic subject who was finally diagnosed as a case of a pancreatic abscess within hepato-gastric ligament and was managed with operative intervention. To the best of the author's knowledge, it is the first-ever reported case of a pancreatic abscess within the hepato-gastric ligament in the world. Literature was reviewed to explore potential etiopathogenesis and therapeutic strategies of this extremely rare condition.
CASE PRESENTATION
A 38 years old gentleman, chronic alcoholic, having a previous history of acute pancreatitis 3 months back, presented with fever (102 degrees Fahrenheit) and a huge [20 cm (horizontal) X 15 cm (vertical)] severely painful swelling in the epigastric region. The swelling was round-shaped, intra-abdominal, fixed to deeper tissue, tense-cystic, poorly trans-illuminant, non-pulsatile and irreducible. Routine blood tests showed leucocytosis (14,500/mm) with neutrophilia and elevated plasma pancreatic amylase and lipase levels. USG and MDCT scan of the whole abdomen revealed a thick-walled echogenic cystic swelling of size 18 cm × 12 cm in the epigastric region. USG guided aspiration of the cyst revealed mixed purulent brownish fluid. The cyst fluid was negative for mucin stain and contained high amylase level with low CEA level, suggesting infected pancreatic pseudocyst. An open drainage procedure was considered through an upper midline laparotomy. Aspiration of the pus mixed cyst fluid along with tissue debris was done. Through irrigation of the cyst was done with normal saline. The cyst wall was de-roofed leaving a small part adherent to the inferior surface of the left lobe of the liver. Later the cyst fluid culture showed significant growth of Escherichia coli. He was put on IV antibiotics. The patient was discharged in a stable condition after 5 days. The histopathological examination confirmed pancreatic abscess. Six months after the operation, the patient is doing well, remaining asymptomatic and there is no sign of recurrence.
CONCLUSIONS
Due to extreme rarity, pancreatic abscess formation within hepato-gastric ligament may be a diagnostic dilemma and requires a high index of suspicion. Surgeons should be aware of this rare clinical entity for prompt management of potential morbidity.

SUMMARY
The UNited RESisdue (UNRES) package for coarse-grained simulations, which has recently been optimized to treat large protein systems, has been implemented on Graphical Processor Units (GPUs). An over 100-time speed-up of the GPU code (run on an NVIDIA A100) with respect to the sequential code and an 8.5 speed-up with respect to the parallel Open Multi-Processing (OpenMP) code (run on 32 cores of 2 AMD EPYC 7313 Central Processor Units (CPUs)) has been achieved for large proteins (with size over 10 000 residues). Due to the averaging over the fine-grain degrees of freedom, 1 time unit of UNRES simulations is equivalent to about 1000 time units of laboratory time; therefore, millisecond time scale of large protein systems can be reached with the UNRES-GPU code.
AVAILABILITY AND IMPLEMENTATION
The source code of UNRES-GPU along with the benchmarks used for tests is available at https://projects.task.gda.pl/eurohpcpl-public/unres.

Comparative Study
Specific criteria are given for several methods of determining the basal body temperature shift. The specific criteria selected have been coded for a uniform interpretation by computer, and interpretations have been compared for 8496 charts. Our results indicate that the method that defines the temperature shift as 0.3 degrees F or more above the running low average for at least 3 consecutive days provides the best concurrent chart interpretation method. A method that creates a smoothed curve that transects the average of all temperatures on a completed graph provides a good retrospective method for identifying the temperature shift. Both the temperature averaging technique and curve smoothing technique identified a temperature shift in more than 95% of the charts with complete temperature readings.

BACKGROUND Acute fibrinous and organizing pneumonia (AFOP) is a newly evolving rare non-infectious lung pathology, characterized by intra-alveolar fibrin balls on histology. It is often difficult to diagnose and is usually mistaken for other lung pathologies. We present an interesting case of AFOP with unusual radiologic findings and disease course. CASE REPORT A 56-year-old woman presented with a 1-day history of high-grade fever, chills, and profuse sweating. She was febrile to 101.2 degree Fahrenheit on presentation. On physical examination, she had decreased air entry in the left upper lobe of the lung. Laboratory testing showed a white cell count of 27,000 cells per microliter of blood with left shift. A chest radiograph showed a left upper lobe consolidation. Computed tomography (CT) of the chest without intravenous contrast showed advanced centrilobular emphysema and left upper lobe consolidation measuring 6.2×5.9 cm. The patient was started on antibiotics. She clinically improved and was discharged on oral antibiotics. After discharge, a trans-bronchial lung biopsy showed acute inflammatory cell infiltrate with intra-alveolar fibrin balls but no hyaline membrane formation or significant eosinophils. These findings were consistent with acute fibrinous and organizing pneumonia. However, she was subsequently lost to follow-up. CONCLUSIONS Our case adds to the literature a new and unusual finding of upper lobe infiltrates, in contrast to most cases presenting as bilateral lower lobe infiltrates. In our case, symptomatic improvement after antibiotic treatment suggests a possible role of antibiotics in management of this entity.

Many infections are transmitted from a donor to a recipient through organ transplantations. The transmission of dengue virus from a donor to a recipient in liver transplantation is a rare entity, and currently, there is no recommendation for screening this virus prior to transplantation. We report a case of transmission of dengue virus from donor to recipient after liver transplantation. The recipient had a history of multiple admissions for hepatic encephalopathy and ascites. He was admitted in the ICU for 15 days for chronic liver disease, ascites, and acute kidney injury before transplantation. The donor was admitted 1 day before transplantation. The donor spiked fever on postoperative day 2 followed by thrombocytopenia and elevated liver enzymes. The donor blood test was positive for dengue NS1 antigen. The recipient also had a similar clinical picture on postoperative day 5 and his blood test was also positive for dengue NS1 antigen. Hence, the diagnosis for posttransplant donor-derived allograft-related transmission of dengue infection was made. Both recipient and donor were treated with supportive measures and discharged after their full recovery on postoperative days 9 and 18, respectively. The effect of immunosuppression on dengue presentation is still unclear and there is lack of literature available. In our case, the recipient developed dengue fever similar to general population without showing any feature of severe graft dysfunction. We have concluded that dengue virus can also be transmitted from donor to recipient, and immunosuppression did not have any adverse effect on the evolution of dengue fever within the recipient. Delhi being a hyperendemic zone, screening for donors (especially in season time) for dengue virus seems to be the best preventive method to control donor-derived transmission of dengue to recipient.

BACKGROUND
Although hyperthermia is a recognized animal teratogen and maternal fever has been associated with birth defects in humans, data on the relationship between high environmental temperatures and birth defects are limited.
OBJECTIVE
To determine whether pregnancies are potentially vulnerable to the weather extremes anticipated with climate change, we evaluated the relationship between extreme summer temperature and the occurrence of birth defects.
METHODS
We performed a population-based case-control study by linking the New York State Congenital Malformations Registry to birth certificates for the years 1992-2006. We selected nonmalformed infants from a 10% random sample of live births as controls. We assigned meteorologic data based on maternal residence at birth, summarized universal apparent temperature (UAT; degrees Fahrenheit) across the critical period of embryogenesis, and estimated adjusted odds ratios (aOR) and 95% confidence intervals (CI) with multivariable logistic regression, controlling for confounders available on the birth certificate.
RESULTS
Among 6,422 cases and 59,328 controls that shared at least 1 week of the critical period in summer, a 5-degree increase in mean daily minimum UAT was significantly associated with congenital cataracts (aOR = 1.51; 95% CI: 1.14, 1.99). Congenital cataracts were significantly associated with all ambient temperature indicators as well: heat wave, number of heat waves, and number of days above the 90th percentile. Inconsistent associations with a subset of temperature indicators were observed for renal agenesis/hypoplasia (positive) and anophthalmia/microphthalmia and gastroschisis (negative).
CONCLUSIONS
We found positive and consistent associations between multiple heat indicators during the relevant developmental window and congenital cataracts which should be confirmed with other data sources.

Heat-not-burn tobacco products, battery powered devices that heat leaf tobacco to approximately 500 degrees Fahrenheit to produce an inhalable aerosol, are being introduced in markets around the world. Japan, where manufacturers have marketed several heat-not-burn brands since 2014, has been the focal national test market, with the intention of developing global marketing strategies. We used Google search query data to estimate, for the first time, the scale and growth potential of heat-not-burn tobacco products. Average monthly searches for heat-not-burn products rose 1,426% (95%CI: 746,3574) between their first (2015) and second (2016) complete years on the market and an additional 100% (95%CI: 60, 173) between the products second (2016) and third years on the market (Jan-Sep 2017). There are now between 5.9 and 7.5 million heat-not-burn related Google searches in Japan each month based on September 2017 estimates. Moreover, forecasts relying on the historical trends suggest heat-not-burn searches will increase an additional 32% (95%CI: -4 to 79) during 2018, compared to current estimates for 2017 (Jan-Sep), with continued growth thereafter expected. Contrasting heat-not-burn's rise in Japan to electronic cigarettes' rise in the United States we find searches for heat-not-burn eclipsed electronic cigarette searches during April 2016. Moreover, the change in average monthly queries for heat-not-burn in Japan between 2015 and 2017 was 399 (95% CI: 184, 1490) times larger than the change in average monthly queries for electronic cigarettes in the Unites States over the same time period, increasing by 2,956% (95% CI: 1729, 7304) compared to only 7% (95% CI: 3,13). Our findings are a clarion call for tobacco control leaders to ready themselves as heat-not-burn tobacco products will likely garner substantial interest as they are introduced into new markets. Public health practitioners should expand heat-not-burn tobacco product surveillance, adjust existing tobacco control strategies to account for heat-not-burn tobacco products, and preemptively study the health risks/benefits, popular perceptions, and health messaging around heat-not-burn tobacco products.
