ABSTRACT

BACKGROUND: Store-and-forward (SAF) tele-dermatology (TD) platforms could help promote coordination between hospital and general practitioners (GPs). However, very little data exists on the performance accuracy and opinions of GPs participating in this type of project in France. METHODS: We report on the diagnostic and management plan accuracy of an SAF-TD platform developed for neighbouring GPs around our hospital compared with routine face-to-face (FTF) dermatological consultation in our department. We also compared the accuracy of SAF-TD with that of the participating GPs. Lastly, we collected feedback from GPs after their participation in this project. RESULTS: Overall, 298 patients were included by 58 GPs between November 2016 and January 2020, of whom 169 (57%) were female, and with a median age of 44.5 years (range 0-96). The diagnostic accuracy of TD was 62% (n=184/298) for the initial hypothesis and 80% (n=239/298) for aggregated diagnostic accuracy. Management plan accuracy for TD was 81% (n=225/277). At least 43% of consultations (n=127/298) met the criteria for preventable consultation. Diagnostic accuracy for the initial hypothesis was significantly lower for GPs than for TD (Odd Ratio [OR]=0.34; 95% Confidence Interval [95% CI]: 0.20-0.56; p<0.0001), as was management plan accuracy (OR=0.23; 95% CI: 0.10-0.46; p<0.0001). Among the responding GPs, 78% (n=29) reported very high satisfaction and 97% would consider integrating this type of programme in their long-term practice, but they highlighted the time-consuming nature of the platform (46%) and the lack of financial compensation (44%). CONCLUSION: SAF-TD in coordination with GPs seems safe and efficient in the management of outpatients, and enjoys a high satisfaction rate among GPs, despite its time-consuming nature and the lack of financial compensation. Healthcare policy should promote financial participation to help the expansion of TD.

ABSTRACT

BACKGROUND: To describe persistent symptoms in long COVID-19 non-severe outpatients and report the 6-month clinical recovery (CR) rate. METHODS: Observational study enrolling outpatients (≥ 18 years) with confirmed non-severe COVID-19 (positive nasopharyngeal RT-PCR or presence of SARS-CoV-2 antibodies) who consulted for persistent symptoms after the first pandemic wave (March-May 2020). CR was assessed at the 6-month visit and defined as complete (no symptom), partial (persistent symptoms of lower intensity) or lack of recovery (no improvement). RESULTS: Sixty-three patients (79% women, mean age: 48 years) enrolled; main symptoms (mean 81 days after acute infection): asthenia/myalgia (77%), dyspnea (51%), headaches (35%), cough (33%). At 6 months (n=56), 30% had complete, 57% partial, and 13% lack of recovery. The proportion of patients with>2 persistent symptoms was 26% at 6 months (main symptoms: dyspnea [54%] and asthenia/myalgia [46%]). CONCLUSION: We observed a slow but high recovery rate at 6 months among these outpatients.

ABSTRACT

INTRODUCTION: Persistent symptoms have recently emerged as a clinical issue in COVID-19. We aimed to assess the prevalence and risk factors in symptomatic non-hospitalized individuals with mild COVID-19. METHODS: We performed a prospective cohort study of symptomatic COVID-19 outpatients, from March to May 2020, with weekly phone calls from clinical onset until day 30 and up to day 60 in case of persistent symptoms. The main outcomes were the proportion of patients with complete recovery at day 30 and day 60 and factors associated with persistent symptoms. RESULTS: We enrolled 429 individuals mostly women (72.5%) and healthcare workers (72.5%), with a median age of 41.6 years [IQR 30-51.5]. Symptoms included: cough (69.7%), asthenia (68.8%), anosmia (64.8%), headaches (64.6%), myalgia (62.7%), gastrointestinal symptoms (61.8%), fever (61.5%), and ageusia (60.8%). Mean duration of disease was 27 days (95%CI: 25-29). The rate of persistent symptoms was 46.8% at day 30 and 6.5% at day 60 consisting in asthenia (32.6%), anosmia (32.6%), and ageusia (30.4%). The probability of complete recovery was 56.3% (95%CI: 51.7-61.1) at day 30 and 85.6% (95%CI: 81.2-89.4) at day 60. Factors associated with persistent symptoms were age>40 (HR 0.61), female sex (HR 0.70), low cycle threshold (HR 0.78), and ageusia (HR 0.59). CONCLUSIONS: COVID-19 - even in its mild presentation - led to persistent symptoms (up to one month) in nearly half of individuals. Identification of risk factors such as age, gender, ageusia and viral load is crucial for clinical management and argues for the development of antiviral agents.

ABSTRACT

OBJECTIVE: To describe clinical, biological, radiological presentation and W4 status in COVID-19 elderly patients. PATIENTS AND METHODS: All patients ≥ 70 years with confirmed SARS-CoV-2 infection and hospitalized in the Infectious Diseases department of the Pitié-Salpêtrière hospital, Paris, France, from March 1st to April 15th 2020 were included. The primary outcome was death four weeks after hospital admission. Data on demographics, clinical features, laboratory tests, CT-scan findings, therapeutic management and complications were collected. RESULTS: All in all, 100 patients were analyzed, including 49 patients ≥ 80 years. Seventy percent had ≥2 comorbidities. Respiratory features were often severe as 48% needed oxygen support upon admission. Twenty-eight out of 43 patients (65%) with a CT-scan had mild to severe parenchymal impairment, and 38/43 (88%) had bilateral impairment. Thirty-two patients presented respiratory distress requiring oxygen support ≥ 6 liters/minute. Twenty-four deaths occurred, including 21 during hospitalization in our unit, 2 among the 8 patients transferred to ICU, and one at home after discharge from hospital, leading to a global mortality rate of 24% at W4. Age, acute renal failure and respiratory distress were associated with mortality at W4. CONCLUSION: A substantial proportion of elderly COVID-19 patients with several comorbidities and severe clinical features survived, a finding that could provide arguments against transferring the most fragile patients to ICU.

ABSTRACT

OBJECTIVES: Overdiagnosis of lyme borreliosis leads to unnecessary and increasingly common antimicrobial treatments. We aimed to evaluate patients receiving long-term antimicrobial treatment for lyme borreliosis. METHODS: We included patients referred to a Parisian teaching hospital between January 1st, 2014 and June 30th, 2019, with a presumed diagnosis of lyme borreliosis for which they were treated with antimicrobials for at least 6 months. RESULTS: Fifteen patients were included (11 women and mean age 44 years). The mean antimicrobial treatment duration was 476 days (180-942). The mean number of antimicrobials was 6.8 per patient (1-18). None of the 15 patients had lyme borreliosis. Nine patients were diagnosed with a mental disorder. CONCLUSION: Overdiagnosis and overtreatment of lyme borreliosis put patients at risk of undiagnosed illnesses and multiple adverse effects of unjustified treatments. The clinical management of such patients requires a comprehensive approach including expertise in mental disorders.

ABSTRACT

Aldosterone stimulates Na(+) reabsorption in the collecting ducts by increasing the activity of the epithelial sodium channel, ENaC. Systemic administration of aldosterone increases alpha ENaC mRNA expression in mammalian kidney, suggesting that the alpha ENaC gene is a target for aldosterone action in the distal nephron. To determine whether aldosterone increases alpha ENaC gene transcription, a portion of the alpha ENaC 5'- flanking region coupled to luciferase was transfected into MDCK-C7 cells, a collecting duct cell line with aldosterone-stimulated Na(+) transport. Both dexamethasone and aldosterone stimulated alpha ENaC-coupled reporter gene activity via the glucocorticoid receptor (GR), and this response correlated with the effect of these hormones on endogenous alpha ENaC expression. The aldosterone-stimulated alpha ENaC expression was blocked by actinomycin D, and aldosterone had no effect on alpha ENaC mRNA decay, confirming a transcriptional effect. In HT-29 cells, a GR/mineralocorticoid receptor (MR)-deficient colonic cell line with constitutive alpha ENaC expression, cotransfection with GR or MR restored aldosterone-stimulated alpha ENaC gene transcription, although aldosterone had a functional preference for MR. Analysis of deletion constructs confirmed that a single imperfect glucocorticoid response element (GRE) is necessary and sufficient to confer the aldosterone responsiveness to the alpha ENaC gene promoter in MDCK-C7 and HT-29 cells. These results confirm that alpha ENaC is an aldosterone-induced transcript in the collecting duct and delineates the molecular mechanism for this effect.

ABSTRACT

The mRNA for the epithelial Na(+) channel gamma subunit (gammaENaC) is regulated developmentally in the lung, colon and distal nephron and in response to Na(+) deprivation and systemic corticosteroids in the distal colon. Because such regulation is likely to be at the level of gene transcription, we examined the function of the promoter and other 5' flanking elements of the human gammaENaC gene. The proximal 5' flanking region contains two GC boxes but does not contain a TATA box. A 450 bp human gammaENaC fragment (-459 to +40) directed the expression of luciferase in H441 cells and primer extension analysis in transfected cells confirmed the correct initiation of human gammaENaC-luciferase chimaeric transcripts. By deletional analysis, GC boxes at -21 and -52 were found to be critical for this promoter activity. To begin to identify transcription factors that bind to the core promoter, a double-stranded oligonucleotide that corresponded to this region was synthesized and tested in a gel mobility-shift assay. Incubation of this radiolabelled oligonucleotide with nuclear extracts from H441 and FRTL5 cells resulted in the formation of four specific and distinct DNA-protein complexes. On the basis of antibody 'supershift' assays, one of these factors corresponds to Sp1, whereas the other three correspond to Sp3. Further upstream, an approx. 300 nt (-1143 to -839) polypurine-polypyrimidine tract (PPy tract) containing internal mirror repeats was identified. When contained in a supercoiled plasmid, the approx. 1200 nt 5' flanking region was sensitive to S1 endonuclease, which was consistent with the formation of an intramolecular triplex DNA ('H-DNA') structure with an unpaired single strand. High-resolution mapping with S1 endonuclease and sequencing of S1-generated clones confirmed that all S1-sensitive sites were within the PPy tract. Finally, a negative regulatory element was identified between -1525 and -1296 that functioned in lung, colon and collecting duct cell lines.

ABSTRACT

Familial middle ear ossicular anomalies are rare. We report on a daughter and her mother with congenital conductive hearing loss. Tympanotomy disclosed hypoplasia of long crus of incus whose tip had been replaced with a fibrous strand. A review suggests that middle ear ossicular anomalies may be inherited as autosomal dominant traits. Most individuals were bilaterally affected. Most isolated cases were affected unilaterally.
