Background: Tuberculosis (TB) is one of the most important infectious diseases worldwide. Bacillus Calmette-Guerin (BCG) is a live attenuated vaccine, entered into the childhood immunization program by the World Health Organization (WHO) in 1974 to prevent TB. One of the relatively common complications of BCG vaccination is regional lymphadenitis. Objectives: This study aimed to determine the lymphadenitis incidence in BCG-vaccinated children in southwest Iran. Methods: In a prospective descriptive study, infants born from March to June 2017 were evaluated for BCG vaccine complications at two, four, six, nine, and 12 months of age in Ahvaz, southwestern Iran. Results: The study enrolled 1,506 infants (794 males and 712 females). Among the vaccinated infants, four (0.26%) had injection site reactions, and 106 (7.03%) presented lymphadenitis (66 males and 40 females). The lymphadenitis rate was significantly higher in males than in females (P = 0.024). The mean age at presentation was 4.28 ± 0.79 months. Suppurative lymphadenitis was seen in 53 (50%) cases and nonsuppurative lymphadenitis in 53 (50%) cases. About 80% of nonsuppurative lymphadenitis resolved entirely or partially after a one-year follow-up. Of 53 cases with suppurative lymphadenitis, 46 (43.4%) developed spontaneous drainage, and seven (6.6%) were drained by needle aspiration. No significant relationship was found between the BCG inoculation site and lymphadenitis rate. No other complications such as osteomyelitis or disseminated BCG infection were observed after one year of follow-up. Conclusions: The relatively high incidence of BCG lymphadenitis in this study may be due to the vaccine strain, young vaccinees, and improper vaccination techniques. In most cases, nonsuppurative lymphadenitis regressed spontaneously, and suppurative lymphadenitis was drained spontaneously or by needle aspiration.

BackgroundThe World Health Organization recommends standardised treatment durations for patients with tuberculosis. We identified and validated a host-RNA signature as a biomarker for individualised therapy durations for patients with drug-susceptible (DS)- and multidrug-resistant (MDR)-tuberculosis.MethodsAdult patients with pulmonary tuberculosis were prospectively enrolled into 5 independent cohorts in Germany and Romania. Clinical and microbiological data, and whole-blood for RNA transcriptomic analysis were collected at pre-defined timepoints throughout therapy. Treatment outcomes were ascertained Treatment outcomes were ascertained by TBNET criteria (6-month culture status/one-year follow-up). A whole-blood RNA therapy end model was developed in a multi-step process involving a machine-learning algorithm to identify hypothetical individual end-of-treatment timepoints.ResultsFifty patients with drug-susceptible (DS)-tuberculosis and 30 patients with MDR-tuberculosis were recruited in the German identification cohorts (DS- and MDR-GIC), 28 patients with DS-tuberculosis and 32 patients with MDR-tuberculosis in the German validation cohorts (DS- and MDR-GVC), and 52 patients with MDR-tuberculosis in the Romanian validation cohort (MDR-RVC). A 22-gene RNA model that defined cure-associated end-of-therapy timepoints was derived from the DS- and MDR-GIC data. The model was superior to other published signatures to accurately predict clinical outcomes for patients in the DS-GVC (AUC=0.94 [95%CI:0.9–0.98]) and suggests that cure may be achieved with shorter treatment durations for tuberculosis patients in the MDR-GIC (mean reduction 218.0 days, 34.2%, p<0.001), the MDR-GVC (mean reduction 211.0 days, 32.9%, p<0.001), and the MDR-RVC (mean reduction of 161.0 days, 23.4%, p=0.001).ConclusionBiomarker-guided management may substantially shorten the duration of therapy for many patients with MDR-tuberculosis.

Background: In 2009, to improve the performance of laboratories and strengthen healthcare systems, the World Health Organization Regional Office for Africa (WHO AFRO) and partners launched two initiatives: a laboratory quality improvement programme called Strengthening Laboratory Management Toward Accreditation (SLMTA), and what is now called the Stepwise Laboratory Quality Improvement Process Towards Accreditation (SLIPTA).Objectives: This study describes the achievements of Rwandan laboratories four years after the introduction of SLMTA in the country, using the SLIPTA scoring system to measure laboratory progress.Methods: Three cohorts of five laboratories each were enrolled in the SLMTA programme in 2010, 2011 and 2013. The cohorts used SLMTA workshops, improvement projects, mentorship and quarterly performance-based financing incentives to accelerate laboratory quality improvement. Baseline, exit and follow-up audits were conducted over a two-year period from the time of enrolment. Audit scores were used to categorise laboratory quality on a scale of zero (< 55%) to five (95% – 100%) stars.Results: At baseline, 14 of the 15 laboratories received zero stars with the remaining laboratory receiving a two-star rating. At exit, five laboratories received one star, six received two stars and four received three stars. At the follow-up audit conducted in the first two cohorts approximately one year after exit, one laboratory scored two stars, five laboratories earned three stars and four laboratories, including the National Reference Laboratory, achieved four stars.Conclusion: Rwandan laboratories enrolled in SLMTA showed improvement in quality management systems. Sustaining the gains and further expansion of the SLMTA programme to meet country targets will require continued programme strengthening.

The benefits of breastfeeding are well established. The World Health Organization and the Centers for Disease Control and Prevention recommend that mothers breastfeed infants for at least one year, but most children are not breastfed that long because of many factors. Breastfeeding mothers face many challenges to continued breastfeeding, including medical conditions that arise during this period, such as postpartum depression and lactational mastitis. Because of a perceived lack of consistent guidance on medication safety, it can be difficult for the family physician to treat these conditions while encouraging mothers to continue breastfeeding. The purpose of the current review is to summarize and clarify treatment options for the osteopathic family physician treating lactating mothers. We specifically focus on the pharmacological management of contraception, postpartum depression, and lactational mastitis.

AbstractObjectivesThe quantitation of BCR-ABL1 mRNA is mandatory for chronic myeloid leukemia (CML) patients, and RT-qPCR is the most extensively used method in testing laboratories worldwide. Nevertheless, substantial variation in RT-qPCR results makes inter-laboratory comparability hard. To facilitate inter-laboratory comparative assessment, an international scale (IS) for BCR-ABL1 was proposed.MethodsThe laboratory-specific conversion factor (CF) to the IS can be derived from the World Health Organization (WHO) genetic reference panel; however, this material is limited to the manufacturers to produce and calibrate secondary reference reagents. Therefore, we developed secondary reference calibrators, as lyophilized cellular material, aligned to the IS. Our purpose was both to re-evaluate the CF in 18 previously harmonized laboratories and to propagate the IS to new laboratories.ResultsOur field trial including 30 laboratories across Latin America showed that, after correction of raw BCR-ABL1/ABL1 ratios using CF, the relative mean bias was significantly reduced. We also performed a follow-up of participating laboratories by annually revalidating the process; our results support the need for continuous revalidation of CFs. All participating laboratories also received a calibrator to determine the limit of quantification (LOQ); 90% of them could reproducibly detect BCR-ABL1, indicating that these laboratories can report a consistent deep molecular response. In addition, aiming to investigate the variability of BCR-ABL1 measurements across different RNA inputs, we calculated PCR efficiency for each individual assay by using different amounts of RNA.ConclusionsIn conclusion, for the first time in Latin America, we have successfully organized a harmonization platform for BCR-ABL1 measurement that could be of immediate clinical benefit for monitoring the molecular response of patients in low-resource regions.

One year after the declaration of the COVID-19 pandemic by the World Health Organization (WHO) and despite the implementation of mandatory physical barriers and social distancing, humanity remains challenged by a long-lasting and devastating public health crisis. Non-pharmacological interventions (NPI) are efficient mitigation strategies. The success of these intense NPI is dependent on the approval and commitment of the population. The launch of a mass vaccination program in many countries in late December 2020 with mRNA vaccines, adenovirus-based vaccines, and inactivated virus vaccines has generated hope for the end of the pandemic. Current issues: The continuous appearance of new pathogenic viral strains and the ability of vaccines to prevent infection and transmission raise important concerns as we try to achieve community immunity against SARS-CoV-2 and its variants. The need of a second and even third generation of vaccines and the possibility of potentially harmful side-effects of the vaccines (i.e. venous thromboembolism ) have already been acknowledged. Perspectives: There is a critical and urgent need for a balanced and integrated strategy for the management of the COVID-19 outbreaks organized on three axes: (1) Prevention of the SARS-CoV-2 infection, (2) Detection and early diagnosis of patients at risk of disease worsening, and (3) Anticipation of medical care (PDA). Conclusion: The “PDA strategy” integrated into state policy for the support and expansion of health systems and introduction of digital organization (i.e. telemedicine, artificial intelligence and machine learning technology) is of major importance for the preservation of citizens’ health and life world-wide.

Introduction: Mobile phone-based interventions in cardiovascular disease are growing in popularity. A randomised control trial (RCT) for a novel smartphone app-based model of care, named TeleClinical Care - Cardiac (TCC-Cardiac), commenced in February 2019, targeted at patients being discharged after care for an acute coronary syndrome or episode of decompensated heart failure. The app was paired to a digital sphygmomanometer, weighing scale and a wearable fitness band, all loaned to the patient, and allowed clinicians to respond to abnormal readings. The onset of the COVID-19 pandemic necessitated several modifications to the trial in order to protect participants from potential exposure to infection. The use of TCC-Cardiac during the pandemic inspired the development of a similar model of care (TCC-COVID), targeted at patients being managed at home with a diagnosis of COVID-19. Methods: Recruitment for the TCC-Cardiac trial was terminated shortly after the World Health Organization announced COVID-19 as a global pandemic. Telephone follow-up was commenced, in order to protect patients from unnecessary exposure to hospital staff and patients. Equipment was returned or collected by a ‘no-contact’ method. The TCC-COVID app and model of care had similar functionality to the original TCC-Cardiac app. Participants were enrolled exclusively by remote methods. Oxygen saturation and pulse rate were measured by a pulse oximeter, and symptomatology measured by questionnaire. Measurement results were manually entered into the app and transmitted to an online server for medical staff to review. Results: A total of 164 patients were involved in the TCC-Cardiac trial, with 102 patients involved after the onset of the pandemic. There were no hospitalisations due to COVID-19 in this cohort. The study was successfully completed, with only three participants lost to follow-up. During the pandemic, 5 of 49 (10%) of patients in the intervention arm were readmitted compared to 12 of 53 (23%) in the control arm. Also, in this period, 28 of 29 (97%) of all clinically significant alerts received by the monitoring team were managed successfully in the outpatient setting, avoiding hospitalisation. Patients found the user experience largely positive, with the average rating for the app being 4.56 out of 5. 26 patients have currently been enrolled for TCC-COVID. Recruitment is ongoing. All patients have been safely and effectively monitored, with no major adverse clinical events or technical malfunctions. Patient satisfaction has been high. Conclusion: The TCC-Cardiac RCT was successfully completed despite the challenges posed by COVID-19. Use of the app had an added benefit during the pandemic as participants could be monitored safely from home. The model of care inspired the development of an app with similar functionality designed for use with patients diagnosed with COVID-19.

Abstract Context.—Orthokeratinized odontogenic cyst (OOC) is a relatively uncommon developmental cyst comprising about 10% of cases that had been previously coded as odontogenic keratocysts. Odontogenic keratocyst was designated as keratocystic odontogenic tumor (KCOT) in the new World Health Organization classification and OOC should be distinguished from KCOT for differences in histologic features and biologic behavior. Objective.—To analyze the clinicopathologic features of 61 cases of OOC in a Chinese population. Design.—Clinicopathologic analysis was performed on 61 cases of OOC. Immunohistochemical expression of Ki-67 and p63 was evaluated in 15 OOCs and 15 typical KCOTs. Results.—The 61 patients with OOC ranged from 13 to 75 years (average, 38.93 years). The lesions developed mainly in the third and fourth decades (57.38%) with a distinct predilection for males (72.13%). Six (9.84%) lesions were found in the maxilla and 55 (90.16%) in the mandible. The most common sites were in the mandibular molar and ramus region. Of the 54 cases with radiographic record, 47 (87.04%) were unilocular and 7 (12.96%) were multilocular radiolucencies. Twenty-seven of the 54 cysts were associated with an impacted tooth. Follow-up of 42 patients revealed no recurrence during an average period of 76.8 months after surgery. Compared with KCOTs, expression level of Ki-67 and p63 was significantly lower in OOCs, suggesting a lower proliferative activity. Conclusion.—Orthokeratinized odontogenic cyst is clinicopathologically distinct from KCOT and should constitute its own clinical entity.

AbstractObjective According to the 2017 report of the World Health Organization (WHO), ∼1.5 million people die from vaccine preventable diseases. The WHO is working to generate and popularize effective vaccination programs. However, the concept of “vaccine rejection,” which first started in Europe and United States, has started to make an impact in Turkey during the past 10 years. It is therefore seen as a growing danger in future. This study was conducted to determine, detect, and prevent the reasons of vaccine rejection that have increased in recent years.Methods A cross-sectional study was conducted between June and December at 2015. In all districts of Konya (n = 31), it was aimed to reach all 242 families who rejected vaccination to their 0 to 2 years old babies. Families having more than one child refused to vaccinate all of their children. A questionnaire consisting of 47 questions was prepared by the researchers, using the standard trainings of the Ministry of Health and the literature. A total of 172 families agreed to participate in this study. The questionnaire was applied to the parents using the telephone interview technique. Data were presented as mean ± standard deviation and percentage.Results About 41.3% (n = 71) of the mothers were high school graduates, 50.6% (n = 87) of their fathers were university graduates. About 82.6% (n = 142) of the participants received examination, treatment and follow-up services from family physicians and family health personnel. About 20.9% (n = 36) of the children were the only children of the family. About 55.8% (n = 96) of the families also refused the vaccination for other children. About 83.7% (n = 144) of the unvaccinated children had infants/children follow-up care. While all participants stated that vaccines had side effects, 31.4% (n = 54) of these believed that vaccines cause autism or paralysis in infants. About 62.2% (n = 107) of their mothers did not receive tetanus vaccine during pregnancy. The highest rate of nonvaccination was with the second dose of hepatitis A vaccine, which 96.5% (n = 166) refused. The most accepted vaccine was the first dose of hepatitis B vaccine, which was refused by 18.0% (n = 31). About 79.7% (n = 137) of the participants did not know the reason for the vaccination and 95.9% (n = 165) thought that the vaccines were not required. All participants received information from the health personnel about the vaccines. While 9.9% (n = 17) of the families thought that vaccines cause infertility, 44.8% (n = 77) did not receive vaccination because the vaccines were produced abroad.Conclusion A growing number of families refuse to have their babies vaccinated. The production of vaccines abroad is a major cause of insecurity. There are also beliefs that vaccines cause infertility. Vaccine production in Turkey should be accelerated and public education about vaccines should be reviewed. Training provided to families about vaccines should also be reviewed.
