ABSTRACT

In Italy, despite strong community-based mental health services, needs assessment is unsatisfactory. Using the Mental Health Clustering Tool (MHCT) we adopted a multidimensional and non-diagnosis dependent approach to assign mental health services users with similar needs to groups corresponding to resources required for effective care. We tested the MHCT in nine Departments of Mental Health in four Italian regions. After a brief training, 318 professionals assessed 12,938 cases with a diagnosis of schizophrenia, depression, bipolar disorder and personality disorder through the MHCT. 53% of cases were 40-59 years, half were females, 51% had a diagnosis of schizophrenia, 48% of cases were clinically severe. Clusters included different levels of clinical severity and diagnostic groups. The largest cluster was 11 (ongoing recurrent psychosis), with 18.9% of the sample, followed by cluster 3 (non-psychotic disorders of moderate severity). The MHCT could capture a variety of problems of people with mental disorders beyond the traditional psychiatric assessment, therefore depicting service population from a different standpoint. Following a brief training, MHCT assessment proved to be feasible. The automatic allocation of cases made the attribution to clusters easy and acceptable by professionals. To what extent clustering provide a sound base for care planning will be the matter of further research.

ABSTRACT

PURPOSE: The objective of this study was to compare the efficacy of a low-cost heat-preserving method in preventing intraoperative hypothermia with that of forced-air warming in a resource-limited setting.

METHODS: In this randomized controlled non-inferiority trial, we recruited children younger than 12 years scheduled for cranial neurosurgery in a large East-African hospital. Patients were block-randomized by age to intraoperative warming measures using Hibler’s method (intervention) or warm air (comparator). Hibler’s group patients were circumferentially wrapped in transparent plastic sheeting (providing a vapor-trap) over a layer of cotton blankets, then laid on an insulating foam mattress. Warm air group patients were treated with forced-air convection via an underlying Snuggle Warm™ Pediatric Full Body mattress. Allocated warming measures were initiated in the operating theatre and discontinued upon anesthesia emergence. Perioperative temperatures were measured using noninvasive forehead probes (SpotOn™). The primary outcome was incidence of hypothermia (core temperature < 36.0° for longer than 5 min). Our null hypothesis was that Hibler’s method is inferior in efficacy to the warm air method by a margin exceeding 20%. Among secondary outcomes were duration of hypothermia as proportion of surgical duration, incidence of postoperative shivering and rescue measure requirements.

RESULTS: We analyzed data for 77 participants (Hibler’s = 38; warm air = 39). There was no significant difference between the Hibler’s and warm air arms of the study in the primary outcome of incidence of hypothermia (59.0% vs. 60.5% respectively; OR 1.07; 95% CI 0.43-2.65; p = .890). However, the risk difference (1.55%; 95% CI -0.20 to -0.24) exceeded the 0.2 margin and non-inferiority could not be declared. There was considerable need for rescue measures in both groups (71.1 0% vs. 69.2%; OR 1.09; 95% CI 0.41-2.90; p = .861). There was no statistically significant difference between groups for any prespecified secondary outcome.

CONCLUSION: Although perioperative core temperatures were not significantly different, we could not declare an inexpensive heat-preserving method non-inferior to warm air convection in preventing intraoperative hypothermia in children undergoing anesthesia for cranial neurosurgery in a resource-limited setting. The extensive need for rescue measures may have masked important differences.

ABSTRACT

INTRODUCTION: Long-term clinical success of non-splinted, posterior, and short implants still is unclear. This prospective cohort study reports the 10-year follow-up of 6-mm implants supporting single crowns in the posterior region, and patient-reported outcomes.

METHODS: Baseline sample comprised 20 patients treated with 46 screw-retained crowns supported by 6-mm implants with moderately rough implant surface. Participants were recalled for a 10-year clinical follow-up to assess survival rates, biologic and mechanic conditions, quality of life (OHIP-14), and treatment satisfaction. Data were collected with clinical-radiographic exams and analyzed using descriptive and inferential statistics.

RESULTS: Fourteen patients with 35 implant-crown units were examined after 127.6 ± 11.8 months. For the entire cohort period, 7/46 implants were lost (survival estimate: 77.7% at 133 months), and mechanic complications occurred in 14/46 units (survival estimate: 66.4% at 116 months). In the Cox models, “maximum occlusal force” had a significant effect for implant loss (p = 0.038) and for prosthetic screw loosening (p = 0.038); “arch” and “bruxism” were not significant. Peri-implant bone loss was 0.4 ± 0.6 mm at 10 years. For peri-implant bone level, “crown-to-implant ratio” (p < 0.001) and “time” (p = 0.001) were significant. Bone levels differed from baseline to 12, 48, and 120 months. Satisfaction VAS was 94.0 ± 7.9 mm and OHIP-14 was 2.3 ± 2.2.

CONCLUSION: Single screw-retained crowns supported by 6-mm implants have an acceptable long-term clinical performance, with stable peri-implant bone levels after 10 years of function.

ABSTRACT

BACKGROUND: People experiencing homelessness are among the most socially and medically vulnerable populations.

OBJECTIVES: To assess the prevalence of comorbid disease and associated risk factors among homeless people admitted to temporary shelters in the City of Tshwane during levels 4 and 5 of the COVID-19 national lockdown in South Africa.

METHODS: A descriptive cross-sectional study design was used. The sample was drawn from secondary data on all individuals placed in temporary shelters constructed by Tshwane during levels 4 and 5 of the COVID-19 lockdown (26 March – 31 May 2020). Descriptive statistics were used to summarise data, and a multivariable logistic regression model was applied to determine factors associated with comorbid disease.

RESULTS: The overall prevalence of comorbid disease among homeless people in temporary shelters in Tshwane was 28.8% (95% confidence interval (CI) 26.9 – 30.8). There was no significant difference in the prevalence of comorbid disease by illicit substance use (29.9% for users v. 29.5% for non-users; p=0.871). In adjusted analyses, being South African (adjusted odds ratio (aOR) 2.06; 95% CI 1.10 – 3.88; p=0.024), being female (aOR 3.73; 95% CI 1.85 – 7.53; p<0.001), being black (aOR 3.43; 95% CI 1.12 – 10.54; p=0.031) or white (aOR 6.11; 95% CI 1.55 – 24.0; p=0.01), and injecting substances (aOR 1.68; 95% CI 1.19 – 2.37; p=0.003) were significantly associated with having comorbid disease.

CONCLUSION: The study found a 28.8% prevalence of comorbid disease among homeless people placed in temporary shelters in Tshwane. In adjusted analysis, being South African, being female, black and white race, and injecting substances were associated with having comorbid disease. Strengthening of public health interventions such as needle and syringe exchange programmes, family planning and access to primary care with health education could improve the healthcare of people experiencing homelessness.

ABSTRACT

BACKGROUND: Contrary to the World Health Organization’s internationally recommended medical certificate of cause of death, the South African (SA) death notification form (DNF) does not allow for the reporting of the manner of death to permit accurate coding of external causes of injury deaths.

OBJECTIVES: To describe the injury cause-of-death profile from forensic pathology records collected for the National Cause-of-Death Validation (NCoDV) Project and compare it with profiles from other sources of injury mortality data. In particular, the recording of firearm use in homicides is compared between sources.

METHODS: The NCoDV Project was a cross-sectional study of deaths that occurred during a fixed period in 2017 and 2018, from a nationally representative sample of 27 health subdistricts in SA. Trained fieldworkers scanned forensic records for all deaths investigated at the forensic mortuaries serving the sampled subdistricts during the study period. Forensic practitioners reviewed the records and completed a medical certificate of cause of death for each decedent. Causes of death were coded to the International Statistical Classification of Diseases, 10th revision (ICD-10), using Iris automated coding software. Cause-specific mortality fractions for injury deaths were compared with Injury Mortality Survey 2017 (IMS 2017) and Statistics South Africa 2017 (Stats SA 2017) datasets. The cause profile for all firearm-related deaths was compared between the three datasets.

RESULTS: A total of 5 315 records were available for analysis. Males accounted for 77.6% of cases, and most decedents were aged between 25 and 44 years. Homicide was the leading cause of death (34.7%), followed by transport injuries (32.6%) and suicide (14.7%). This injury cause profile was similar to IMS 2017 but differed markedly from the official statistics, which showed markedly lower proportions of these three causes (15.0%, 11.6% and 0.7%, respectively), and a much higher proportion of other unintentional causes. Investigation of firearm-related deaths revealed that most were homicides in NCoDV 2017/18 (88.5%) and IMS 2017 (93.1%), while in the Stats SA 2017 data, 98.7% of firearm deaths were classified as accidental. Approximately 7% of firearm-related deaths were suicides in NCoDV 2017/18 and IMS 2017, with only 0.3% in Stats SA 2017.

CONCLUSION: The official cause-of-death data for injuries in SA in 2017 differed substantially from findings from the NCoDV 2017/18 study and IMS 2017. Accurate data sources would ensure that public health interventions are designed to reduce the high injury burden. Inclusion of the manner of death on the DNF, as is recommended internationally, is critically important to enable more accurate, reliable and valid reporting of the injury profile.

ABSTRACT

BACKGROUND: Upon the addition of the numbers corresponding to various cancer anatomical locations in the report published by Statistics South Africa (StatsSA), the absolute number and proportion of deaths due to all cancers increased from 36 726 (8.0%) in 2013 to 40 460 (8.5%) in 2015. These high figures suggest that malignant neoplasms were in fact the second-most frequent cause of death in South Africa (SA) in 2013, and moved to the first rank in 2015.

OBJECTIVES: To support the initiative aimed at reducing cancer mortality in SA. To this purpose, we assessed trends in cancer mortality rates among males and females in SA from 1997 to 2016 to better understand the increasing threat of cancer mortality in SA.

METHODS: The general mortality data for the period 1997 – 2016, as captured from death certificates in SA, was retrieved from StatsSA. Agestandardised mortality rates (ASMR) for each year were computed using the world standard population structure proposed by Segi as the reference population. The adjusted rates were reported per 100 000 population per year. The years of potential productive life lost (YPPLL) due to cancer deaths were calculated for each age group and gender.

RESULTS: There were 681 689 total cancer deaths from 1997 to 2016, with 51.1% males and 48.9% females. Males had higher mortality rates than females. The ASMR ranged from 105.0 to 129.2 and 67.9 to 88.3 per 100 000 population per year among males and females, respectively. In 2004, the cancer mortality rate increased significantly among males (129.2 per 100 000 population), which was 1.5 times higher than in females (88.3 per 100 000 population). Among males, cancer of the lung had the highest YPPLL (394 779.3), followed by oesophageal (253 989.4) and liver (207 911.0). The YPPLL for cancer of the cervix (647 855.5) ranked first, followed by breast (483 863.6) and lung (146 304.6) in females.

CONCLUSION: Cancer mortality rates have increased since 1997, regardless of gender. Overall, there was a decline in YPPLL for cancer in the young population, while it increased in the adult population. A significant reduction in cancer deaths could be achieved by broadly applying effective interventions.

ABSTRACT

BACKGROUND: Thyroid cancer is prevalent both internationally and locally, and is the most common cause of endocrine malignancies in Africa. The prognosis of thyroid cancer in general is quite good, but to achieve good outcomes, appropriate methods for diagnosis are important. A cytology result obtained from a fine needle aspiration and biopsy (FNAB) is one such method, and is less invasive and has less risk compared with obtaining a histological result via open surgery. However, there are accuracy differences that have been reported in different literature findings.

OBJECTIVES: To determine the diagnostic accuracy rate of thyroid FNAB compared with histopathological samples at an urban hospital in South Africa (SA), and compare this with international standards.

METHODS: A retrospective observational study was conducted of patients who had undergone both FNAB and thyroidectomies at Helen Joseph Hospital, Gauteng Province, SA, a public tertiary hospital, between 1 January 2016 and 31 December 2021. Various analytical methods were used, including Poisson generalised linear model, binomial generalised linear model, a two-proportion z-test, McNemar’s test and the F1 score.

RESULTS: There were 164 participants in this study who were between the ages of 21 and 82 years old. Thirty-six records were excluded for use as a comparison between cytology and histology, as they were in Bethesda categories 1, 3 and 4. Out of the 128 records that were compared, there was statistically significant agreement v. non-agreement between cytology and histology findings for thyroid nodules (109 v. 19, p<0.001, respectively). A comparison between our sample population and internationally published standards in terms of rate of malignancy noted that our rate of malignancy was slightly higher in Bethesda 2 patients (5.88%) v. internationally published standards (0 – 3%), and slightly lower in Bethesda 4 (23.52%) and 6 (77.77%) v. internationally published standards (25 – 40% and 97 – 99%, respectively.

CONCLUSION: There was good correlation between cytology and histology for thyroid nodules. Differences were noted between the percentage of malignant cases in the different Bethesda categories compared with international standards as noted above. We recommend that further studies are conducted locally to improve knowledge on this topic.

ABSTRACT

OBJECTIVE: Becker muscular dystrophy (BMD) is a milder variant of Duchenne muscular dystrophy (DMD), a lethal X-linked muscular disorder. Here, we aim to investigat the clinical involvement of skeletal, respiratory, cardiac, and central nervous systems in patients with BMD, as well as genotype-phenotype relationships.

METHODS: This nationwide cohort study investigated the clinical manifestations and genotype-phenotype relationships in 225 patients with BMD having in-frame deletion from 22 medical centers. The primary outcome was to elucidate the association of genotype with skeletal muscle, respiratory, cardiac, and central nervous system disorders. Descriptive statistics were used to analyze the data.

RESULTS: The average age of the subjects was 31.5 (range, 1-81) years. Initial symptoms of BMD were muscular (60%), followed by asymptomatic hypercreatine kinasemia (32.4%) and central nervous system disorders (5.3%). Gait disturbance was observed in 53.8% of patients and the average age at wheelchair introduction was 36.5 years. The ventilator introduction rate was 6.7% at an average age of 36.6 years. More than 30% of patients had an abnormal electrocardiogram and approximately 15% had heart failure symptoms. Cardiac function on echocardiography varied significantly among the patients. The frequencies of seizures and intellectual/developmental disability were 8.0% and 16.9%, respectively. Exon 45-47deletion (del) was the most common (22.6%), followed by exon 45-48del (13.1%). Patients with exon 45-49del patients demonstrated severe skeletal muscle damage. Patients with exon 45-47del and exon 45-55del patients did not require ventilator use.

INTERPRETATION: The study provides important prognostic information for patients and clinicians to establish therapy plans and to implement preventative medicine.

ABSTRACT

BACKGROUND/OBJECTIVES: Favipiravir is an antiviral agent, recently used for COVID-19 infections. Several reports associate favipiravir intake with Wood’s lamp fluorescence of hair, nails, and sclera. The present study was designed to elucidate the positivity rates, and sites of favipiravir-related fluorescence and to unravel the site-specific changes in fluorescence positivity rates by a function of time past exposure.

METHODS: The study population comprised 50 patients and 50 control individuals. All patients in the patient group had received a full dose of favipiravir for COVID-19 infection. Fifty volunteers served as the control group. Wood’s lamp examination was performed in a completely darkened room, and the positivity rate, extent, pattern, and distribution of fluorescence were recorded.

RESULTS: Wood’s light revealed fluorescence of the fingernails, toenails, sclera, and hair in 35 (70%), 35 (70%), 22 (44%), and 8 (16%) patients, respectively. No control individual tested positive by Wood’s lamp. Statistical analysis revealed significant differences between patient and control groups in terms of Wood’s light luminescence in the fingernails (p = .000), toenails (p = .000), sclera (p = .000) and hair (p = .003). Although fingernail, toenail, and hair fluorescence positivity rates declined or ceased at or after 91 days of favipiravir exposure, ocular fluorescence positivity rates were prolonged up to 188 days.

CONCLUSIONS: These findings confirm that favipiravir may produce fluorescence of nails, sclera, and hair, detectable by Wood’s light starting from the initial month and peaking at second- and third months following exposure to the medication. Although nail and hair fluorescence tend to abate after 3 months, ocular fluorescence may persist even longer than 6 months after cessation of the medication.

ABSTRACT

INTRODUCTION: The management of motor fluctuations in Parkinson’s disease (PD) can be challenging, and current therapeutic options include the use of monoamine oxidase B inhibitors (MAO-B inhibitors), among others. The aim of this study was to evaluate the effectiveness and safety of safinamide in the clinical practice carried out in the Toledo Movement Disorders Unit.

PATIENTS AND METHODS: This is a retrospective study in which data were collected at baseline and at six months from PD patients who were started on safinamide as an add-on therapy with a stable dose of levodopa in line with standard clinical practice. An analysis was performed by subgroups: patients who were given low-dose safinamide and patients who previously received rasagiline.

RESULTS: Ninety patients (47 previously received rasagiline) completed the six-month follow-up. A statistically significant decrease in morning akinesia, nocturnal akinesia, wearing off, unpredictable off phenomenon and Unified Parkinson’s Disease Rating Scale-III was observed both in those who previously received rasagiline and in those treated with low doses of safinamide. No variation was found in the dyskinesias. The adverse events described were mild, with generalised weakness, dizziness, nausea, headache and alopecia.

CONCLUSIONS: Safinamide has been shown to be effective and safe in improving motor fluctuations, motor symptoms and the subjective perception of disease severity in PD patients previously receiving rasagiline and in those receiving low-dose safinamide, all of which is accompanied by a good safety profile.
