Symptom Diary–Based Analysis of Disease Course among Patients with Mild Coronavirus Disease,Germany, 2020

Limited information is available on the clinical course of outpatients with mild coronavirus disease (COVID-19). This information is critically important to inform public health prevention strategies and to provide anticipatory guidance to patients, primary care providers, and employers. We retrospectively assessed the daily prevalence of symptoms in 313 COVID-19 outpatients for the first 20 days of illness. Generalized estimating equations were used to assess the probability of symptom occurrence over time. Fatigue (91%), cough (85%), and headache (78%) were the most common symptoms and occurred a median of 1 day from symptom onset. Neurologic symptoms, such as loss of taste (66%) and anosmia (62%), and dyspnea (51%) occurred considerably later (median 3–4 days after symptom onset). Symptoms of COVID-19 are similar to those of other respiratory pathogens, so symptomatic patients should be tested more frequently for severe acute respiratory syndrome coronavirus 2 during influenza season to prevent further spread of COVID-19.     

Hepatitis B and C in liver transplantation: new strategies to combat the enemies

Hepatitis B immune globulin‐free therapeutic regimens with a nucleos(t)ide analogue (NUC) or NUC combinations after liver transplantation (LT) are currently being investigated for their efficacy and safety as HBV re‐infection prophylaxis in clinical studies. Recurrence rates differ among these studies as most of them are limited by a non‐randomised study design, small sample size, lack of long‐term data and varying time intervals for the switch from combined to purely virostatic prophylaxis. Post‐transplant pre‐emptive antiviral therapy with pegylated IFN and ribavirin is associated with low sustained virological response rates and was found to have no advantage over treatment of manifest HCV re‐infection. Safety and efficacy of triple antiviral therapy including boceprevir or telaprevir in patients with manifest HCV re‐infection are currently under investigation in clinical trials. Relevant drug interactions have been shown to occur during calcineurin inhibitor (CNI) and concomitant triple antiviral therapy, which vary with type of CNI and choice of HCV protease inhibitor. Newer direct‐acting antivirals with lower or minimal toxicity, when used in combination with immunosuppressives, are worthy of further study in LT patients. This review focuses on hot topics in the management of hepatitis B and C patients before and after LT and offers a critical summarised selection of the corresponding relevant studies published in the current literature or presented at recent liver congresses.

Preparation and characterization of co-processed starch/MCC/chitin hydrophilic polymers onto magnesium silicate

It was aimed to investigate the compressibility, compactibility, powder flow and tablet disintegration of a new excipient comprising magnesium (Mg) silicate co-processed (5%–85% w/w) onto chitin, microcrystalline cellulose (MCC) and starch as the hydrophilic polymers of interest. Initially, the mechanism of tablet disintegration was studied by measuring water infiltration rate, moisture sorption, swelling capacity and hydration ability. Moreover, the powders compression behavior was carried out by applying Kawakita model of compression analysis in addition to porosity and radial tensile strength measurements. In vitro drug release of compacts made of 400?mg ibuprofen and 300?mg of the hydrophilic polymers containing 30% w/w Mg silicate co-precipitate was investigated in phosphate buffer (pH 7.8). This work demonstrated that the incorporation of Mg silicate to the hydrophilic polymers lead to the improvement of powder flowability, compactibility, stability (with regard to storage conditions), compacts crushing strength, and disintegration time in addition to faster drug release. The overall findings are practically advantageous in the context of finding a low cost and multifunctional co-processed excipient of natural origins.     

Apremilast in the Treatment of Chronic Prostatitis/Chronic Pelvic Pain Syndrome: A Pilot Study

Objective: Chronic prostatitis/chronic pelvic pain syndrome (CP/CPPS) is a disease with an uncertain cause and limited effective treatments. Apremilast (Celgene Corporation, Summit, NJ, USA) is a selective phosphodiesterase type 4 (PDE4) inhibitor that modulates the immune system. An open‐label, one‐arm, pilot study was conducted to explore its potential for improving CP/CPPS symptoms. Methods: Males ≥ 18 years of age were treated with 20 mg oral apremilast twice daily for up to 12 weeks. Outcomes were measured with Global Response Assessment (GRA), pain visual analog scale (VAS), Chronic Prostatitis Symptom Index (CPSI), Pittsburgh Sleep Quality Index (PSQI), SF‐12 mental (MCS) and physical (PCS) health‐related quality of life subscales, and voiding diaries. Repeated measures and paired t‐tests evaluated changes from baseline to end of treatment, and at a final visit 4 weeks off the drug. Results: Seventeen men (94% Caucasian; mean age 48.2 ± 10 years) were treated (mean 115.8 ± 56.1 doses). Mean VAS (3.4 ± 2.0 vs 1.8 ± 1.7; P = 0.0011), PSQI (9.4 ± 4.4 vs 7.4 ± 4.2; P = 0.037) and CPSI (26.1 ± 5.0 vs 17.2 ± 8.3; P = 0.0016) scores improved from baseline to end of treatment. Incontinence episodes per day improved slightly (P = 0.042). When only those completing at least 8 weeks of treatment were examined (n = 9), significant changes in CPSI, VAS, and PSQI were still observed. At the final visit, 8/9 (88.9%) men also reported some improvement in pain related to sex. Side‐effects were generally mild and well tolerated. Conclusion: These results suggest that apremilast may improve CP/CPPS symptoms with only mild side‐effects. However, placebo controlled studies are necessary to determine efficacy.     

Do various degrees of tooth decalcification affect orthodontists', general dentists' and laypersons' ratings of smile esthetics?

ObjectivesTo compare the effect of various degrees of decalcification after orthodontic treatment (white spot lesions) on orthodontists'', general dentists'', and laypersons'' ratings of smile esthetics.Materials and MethodsEight photographs representing incrementally altered tooth decalcification lesions of maxillary anterior teeth ranging from mild to severe were shown randomly to the study participants. Photographs were rated by a matched sample of orthodontists (N = 42), general dentists (N = 52), and laypeople (N = 58). A visual analogue scale (VAS) was used to assess perceptions of smile esthetics.ResultsThe three groups of raters could distinguish between different decalcification levels. Raters gave more negative scores as the decalcification level increased.ConclusionsThe three groups of raters were able to distinguish between various degrees of decalcification lesions. General dentists were the most critical of all groups when rating decalcification lesions.     

Treatment and outcomes of acute coronary syndrome in the cancer population

Background:

Randomized trials have established the benefit of medical therapy and revascularization in the treatment of acute myocardial infarction (MI). Cancer and cardiovascular disease are the 2 most common diseases worldwide. In clinical practice, cancer patients are frequently afflicted with MI. The benefit of medical and/or revascularization therapy in the cancer population with MI is less well known.

Hypothesis:

Medical and revascularization therapy reduces mortality in cancer patients with MI.

Methods:

After approval by the institutional review board, we retrospectively reviewed all patients with a discharge diagnosis of acute MI who were admitted to the University of Texas MD Anderson Cancer Center between December 2000 and October 2006 and evaluated the association between cardiac treatments with survival outcomes.

Results:

A total of 456 patients with a discharge diagnosis of acute MI were identified and included in the study, of which 386 had non–ST‐segment elevation MI (NSTEMI) and 70 had ST‐segment elevation MI (STEMI). Compared with patients with NSTEMI, patients who had STEMI were more often prescribed aspirin (66% vs 43%; P = 0.004), β‐blockers (61% vs 46%; P = 0.018), and thrombolytic therapy (9% vs 0.3%; P = 0.0001). In the multivariable analysis, aspirin use was associated with a 23% decreased risk of death (hazard ratio [HR]: 0.77, 95% confidence interval [CI]: 0.60‐0.98, P = 0.033) and β‐blocker use was associated with a 36% decreased risk of death (HR: 0.64, 95% CI: 0.51–0.81, P = 0.0002). Statins (HR: 0.82, P = 0.18) and catheter‐based revascularization (HR: 0.57, P = 0.09) did not have an impact on the risk of death. Compared with patients with limited cancer, advanced cancer patients were twice as likely to die (HR: 2.12, 95 CI: 1.47–3.04, P < 0.0001). Previous chemotherapy (P = 0.005) and chest radiotherapy (P = 0.017) were associated with increased 1‐year mortality, whereas hyperlipidemia (P = 0.018) was protective.

Conclusions:

In this study of cancer patients with MI, medical therapy with aspirin and β‐blockers was associated with improved survival. The authors have no funding, financial relationships, or conflicts of interest to disclose.     

Variables Associated with Stress Ulcer Prophylaxis Misuse: A Retrospective Analysis

Background

Stress ulcer prophylaxis (SUP) is commonly used in hospitals. Although its indications are better delineated for intensive care unit (ICU) patients, its use in non-ICU settings is somewhat arbitrary and based on judgment.

Objective

We attempted to assess the extent of SUP overuse in our hospital. We also carefully collected and analyzed several variables to detect associations governing this flawed behavior and its financial burden on the hospital’s budget.

Materials and Methods

We retrospectively analyzed charts of patients admitted to the medical floor of a tertiary referral university hospital over a 1 year period. All adult patients admitted to the medical ward who received at least one dose of SUP were included and reviewed for a multitude of variables in addition to the appropriateness of acid suppression therapy (AST).

Results

We included 320 charts and found that 92% of patients admitted during that period were not eligible for SUP. The total inappropriateness of SUP was noted to be 58% (p = 0.015). Increasing age and male gender were found to be significant variables in AST misuse (p = 0.045 and p = 0.010), much like duration of hospital stay (p = 0.008). Comorbidities was also found to be a defining variable for AST overuse (odds ratio [OR] = 3.27). Patients with two or more minor risk factors were also subjected more to SUP inappropriately (OR = 3.53), in addition to patients of certain specialties (Neurology, Infectious Diseases, etc.). Our calculated financial burden was more than $23,000 per year for the medical floor.

Conclusion

This retrospective study confirmed the growing suspicion that SUP misuse is evident on the medical floors. We also delineated several factors and variables associated with and affecting SUP overuse.
