Authors: Moustafa Iman , Saka Sule , Viljoen Michelle , Oosthuizen Frasia 
Published: February 2022

Objective Doxorubicin, a component of the anthracycline group, is a highly effective in the treatment of hematologic and solid malignancies. Because of the cardiotoxic adverse effects, use is limited. Antioxidants may negate this anthracycline-induced cardiotoxicity, although the literature is not conclusive with regards to the cardioprotective benefits of antioxidants. This review assessed and mapped evidence of the efficacy of vitamin E and levocarnitine against doxorubicin-induced cardiotoxicity in adult cancer patients. Data Sources This review was based on the Arksey and O’Malley methodology. Potentially relevant literature in English published between January 1960 and April 2021 was identified through a database search. Oxford Quality Scoring System and AMSTR2 were used to assess the quality of trials and systematic reviews respectively, as well as the risks of potential bias. Data Summary Nineteen of the 10 268 (0.2%) articles from the initial search were included in the final analysis (12 clinical trials and 7 systematic reviews). Vitamin E was included in seven prospective clinical trials. Levocarnitine was included in five clinical trials as an individual agent and a single trial as a combination treatment. No trials could be found investigating the combination of vitamin E and levocarnitine in humans. Conclusions This review found that levocarnitine trials showed some cardioprotective effects but the results from vitamin E trials were controversial and inconclusive. Most of the trials reviewed had some shortcomings. Further investigations are therefore needed to determine the efficacy of vitamin E and levocarnitine in preventing doxorubicin-induced cardiotoxicity in adult cancer patients.

Aim: In Denmark, rural-provincial Lolland-Falster currently has the highest mortality, caused mainly by the high mortality of in-migrating people. To identify possible preventive measures to combat this excess mortality insight into the underlying diseases is needed. Methods: We used data from Danish registers to calculate cause-specific mortality for 1970–1979, 1980–1989, 1990–1999, 2000–2009 and 2010–2018 divided into cancer, cardiovascular diseases, respiratory diseases, external causes and other causes (all remaining causes). We calculated age-standardised mortality rates for Lolland-Falster and the rest of Denmark: mortality rate ratios and excess number of deaths per 100,000 person-years for Lolland-Falster distinguishing between long-term residents (10+ years) and in-migrants. Results: In 1970–1979, the age-standardised mortality rates for Lolland-Falster resembled those for rest of Denmark. Over time, age-standardised mortality rates for cardiovascular diseases decreased but more so for the rest of Denmark than for Lolland-Falster. Age-standardised mortality rates for other diseases increased but more so for Lolland-Falster than for the rest of Denmark. The excess mortality in Lolland-Falster derived in particular from in-migrants: in 2010–2018 the mortality rate ratios for this population reached 2.29 (95% confidence interval 1.96–2.69) for external causes and 2.12 (95% confidence interval 1.97–2.29) for other diseases. In-migrants had in total 411 excess deaths per 100,000 person-years. Of these 27% came from tobacco smoking-related causes of death. However, another 25% came from ill-defined, unspecified and a broad range of other, minor causes of deaths. Conclusions: The excess mortality of in-migrants to Lolland-Falster was attributable to all main causes of deaths, which stresses the complexity in combatting geographical disparities in mortality.
Dementia and its impacts on the intimate, sexual couple relationship: A systematic review of qualitative research studies
Authors: Albert Susan Carol , Eduardo Martinelli José , Costa Pessoa Maria Silvia 
Published: February 2022

Objective There is growing evidence for the need to recognize persons with dementia as sexual beings who wish to continue expressing their sexuality, including within their couple relationship. The aim of this literature review was to investigate empirical qualitative studies that examined sexuality and sexual intimacy in the couple relationship when one spouse has dementia. Method A systematic literature review was performed in January 2021, five data bases were searched: Pubmed, MedLine, Lilacs, Scopus, and SciELO. The references of articles included in the review were screened together with the references of other relevant reviews. Results Nine studies were identified that investigated sexuality and sexual intimacy from the perspective of the couple living with dementia or from the perspective of the spouse. The analysis identified four key themes: addressing dementia and sexuality; challenges to maintaining sexuality within the couple relationship; forms of sexual expression; and the desire to be seen as a sexual being. Conclusion Despite evidence of the importance of sexuality in later life and the positive effects it has on the quality of the couple relationship, research has identified the difficulty of destigmatizing sexuality and older persons, particularly when considering couples affected by dementia. Further research is required to better understand how living with the illness impacts sexual expression and the intimacy of the couple relationship.

Published: February 2022

Porphyria is a metabolic disorder caused by a mutation in the heme biosynthetic pathway, with vague symptomatology and rare prevalence. A triad of hyponatremia, intermittent seizures, and abdominal pain should raise suspicion for porphyria. The diagnosis is based on increased blood porphobilinogen levels and genetic mutations. Treatment involves Dextrose-10 administration followed by hematin infusions as soon as possible. A maintenance dose of hematin is required in some cases. Here, we report a delayed diagnosis of acute intermittent porphyria (AIP) in an 18-year-old female, who first presented with severe anemia attributed to iron deficiency from menstrual blood loss. After discharge, she was readmitted with bilateral lower extremity and abdominal pain, hyponatremia, and seizure attributed to polypharmacy. During this second hospitalization, she was transferred to our hospital complaining of chest pain, shortness of breath, markedly decreased weakness, dysphagia, and hallucinations. After an extensive workup, she was diagnosed with AIP, and Dextrose-10 and hemin infusion were started. Our patient was found to have a missense mutation in the Hydroxymethylbilane synthase gene. She recovered after an extended ICU stay of 45 days and was discharged with a moderate improvement of weakness. Early diagnosis is necessary to prevent severe manifestations and long-term sequelae, such as axonal neuropathy, which occurred in the presented case.

Introduction: COVID-19 vaccines became available after being carefully monitored in clinical trials with safety and efficacy on the human body. However, a few recipients developed unusual side effects, including cerebral venous sinus thrombosis (CVST). We aim to systematically review the baseline features, clinical characteristics, treatment, and outcomes in patients developing CVST post-COVID-19 vaccination. Methods: This study was conducted according to the PRISMA (Preferred Reporting Items for Systematic Review and Meta-Analysis) 2020 guideline. Investigators independently searched PubMed, Embase, and Google Scholar for English language articles published from inception up until September 10, 2021, reporting the incidence of CVST post-COVID-19 vaccines. We analyzed CVST patients’ baseline data, type of vaccines, clinical findings, treatment, and outcomes. Our systematic review process yielded patient-level data. Result: The final analysis included 25 studies that identified 80 patients who developed CVST after the COVID-19 vaccination. Of the 80 CVST cases, 31 (39.24%) patients died. There was no significant relationship between mortality and age ( P = .733), sex ( P = .095), vaccine type ( P = .798), platelet count ( P = .93), and comorbidities such as hypertension ( P = .734) and diabetes mellitus ( P = .758). However, mortality was associated with the duration of onset of CVST symptoms after vaccination ( P = .022). Patients with CVST post-COVID-19 vaccination were more likely to survive if treated with an anticoagulant ( P = .039). Patients who developed intracranial hemorrhage ( P = .012) or thrombosis in the cortical vein ( P = .021) were more likely to die. Conclusion: COVID-19 vaccine-associated CVST is associated with high mortality rate. Timely diagnosis and management can be lifesaving for patients.

Published: February 2022

Background: Bicipital disorders are common among overhead athletes, especially professional baseball players. The ideal treatment for bicipital problems in professional baseball players is unknown. Purpose/Hypothesis: The purpose was to determine the return-to-sport (RTS) rate and performance after RTS in professional baseball players who underwent biceps tenodesis. It was hypothesized that there will be a high RTS rate in this population, with no difference between the biceps tenodesis and control groups in the RTS rate or performance. Study Design: Case series; Level of evidence, 4. Methods: All professional Major League Baseball players who underwent biceps tenodesis between 2014 and 2017 were included. Players with concomitant rotator cuff repair were excluded. Demographic and performance data (preoperative and postoperative) were recorded for each player. Performance metrics were then compared between players with biceps tenodesis and matched controls (no history of biceps tenodesis). Results: Included were 14 players (mean age, 27 ± 4 years; 12 pitchers, 2 position outfielders). Most surgeries (79%) were open subpectoral tenodeses, 2 were arthroscopic biceps transfers, and 1 was an arthroscopic suprapectoral tenodesis. Fixation methods included cortical button (42%), interference screw (25%), suture anchor (25%), and drill holes (8%). Most players (79%) underwent concomitant procedures (43% underwent superior labral anterior-posterior repairs). While 86% (12/14) were able to RTS, 50% (7/14) returned at the same or a higher level, and 50% of the whole study were either unable to return or returned to a lower level. Among pitchers, 100% (12/12) were able to RTS, but only 50% (6/12) were able to return to the same or a higher level. For those players who did RTS, it took 245 ± 84 days, and their performance after RTS was unchanged and did not differ from that of matched controls. Conclusion: Open subpectoral tenodesis was the most common tenodesis technique performed on professional baseball players. While 86% of players returned to sport after biceps tenodesis, only 50% returned to the same or higher level. No decline in performance was noted in players who returned successfully.

Introduction: Markers of poor oral health are associated with impaired cognition and higher risk of Alzheimer disease (AD) and thus may help predict AD. Objectives: The aim of this study was to evaluate the cross-sectional association between empirically derived groups of 19 IgG antibodies against periodontal microorganisms and cognition in middle-aged and older adults. Methods: The study population consisted of participants of the third National Health and Nutrition Examination Survey (NHANES III) (1988 to 1994), who were 60 y and older, among whom cognition and IgG antibodies against 19 periodontal microorganisms were measured (N = 5,162). Results: In multivariable quantile regression analyses, the Orange-Red (Prevotella melaninogenica, Prevotella intermedia, Prevotella nigrescens, Porphyromonas gingivalis) and Yellow-Orange (Staphylococcus intermedius, Streptococcus oralis, Streptococcus mutans, Fusobacterium nucleatum, Peptostreptococcus micros, Capnocytophaga ochracea) cluster scores were negatively associated with cognition. A 1-unit higher cluster score for the Orange-Red cluster was associated on average with a lower cognitive score (β for 30th quantile = −0.2640; 95% confidence interval [CI], −0.3431 to −0.1848). Similarly, a 1-unit higher score for the Yellow-Orange cluster was associated with a lower cognitive score (β for 30th quantile = −0.2445; 95% CI, −0.3517 to −0.1372). Conclusion: Groups of IgG antibodies against periodontal microorganisms were associated with lower cognition among free living adults 60 years and older, who were previously undiagnosed with cognitive impairment. Though poor oral health precedes the development of dementia and AD, oral health information is currently not used, to our knowledge, to predict dementia or AD risk. Combining our findings with current algorithms may improve risk prediction for dementia and AD. Knowledge Translation Statement: IgG antibodies against periodontal microorganisms were associated with lower cognition among adults 60 years and older previously undiagnosed with cognitive impairment. Periodontal disease may predict cognition among older adults.
Historical expectations with DNA methyltransferase inhibitor monotherapy in MDS: when is combination therapy truly “promising”?
Authors: Brunner Andrew M. , Fell Geoffrey , Steensma David P. 
Published: February 2022

Abstract
DNA methyltransferase inhibitors (DNMTIs) for patients with higher risk myelodysplastic syndromes (HR-MDS) have low complete remission rates and are not curative. Early DNMTI combination clinical trials in HR-MDS are often termed “promising,” but many randomized trials subsequently failed to show benefit. Clearer understanding of when a combination is likely to improve upon DNMTI monotherapy would inform randomized studies. We reviewed MDS azacitidine or decitabine monotherapy studies. We collected baseline demographics including International Prognostic Scoring System (IPSS) risk, DNMTI, disease characteristics; and response variables including survival and marrow and hematologic responses. Aggregate estimates across studies were calculated using meta-analyses techniques. Using a binomial design, we estimated the necessary operating characteristics to design a phase 2 study showing improved efficacy of a combination over monotherapy. Among 1908 patients, the overall response rate (ORR) was 24% (n = 464; 95% confidence interval [CI], 0.22-0.26): 267 complete response (CR, 14%), 68 partial response (4%), and 129 marrow complete remission (7%). Among 1604 patients for whom a hematologic response was reported, 476 (30%; 95% CI, 0.27-0.32) reported hematologic improvement (HI). More patients treated with azacitidine achieved HI (38%; 95% CI, 0.35-0.41) compared with decitabine (15%; 95% CI, 0.13-0.19), whereas the marrow ORR rate was higher with decitabine (29%; 95% CI, 0.26-0.33) compared with azacitidine (21%; 95% CI, 0.19-0.23). CR rates were similar between DNMTIs: 13% with azacitidine and 16% with decitabine. Variables that influence MDS response include the specific DNMTI backbone and the distribution of IPSS risk of patients enrolled on a trial. Considering these factors can help identify which early combination approaches are worth assessing in larger randomized trials.

Published: February 2022

Abstract
Background
Peptic ulcer disease (PUD) is a common digestive disorder, of which the prevalence decreased in the past few decades. However, the decreasing tendency has plateaued in recent years due to changes in risk factors associated with the etiology of PUD, such as non-steroidal anti-inflammatory drug use. In this study, we investigated the epidemiological and the sociodemographic characteristics of PUD in 204 countries and territories from 1990 to 2019 based on data from the Global Burden of Disease, Injuries and Risk Factors (GBD) Study.

Methods
Demographic characteristics and annual prevalence, incidence, mortality, disability-adjusted life years (DALYs) and age-standardized death rate (ASR) data associated with PUD were obtained and analyzed. According to the sociodemographic index (SDI), the numbers of patients, ASRs, estimated annual percentage changes and geographical distributions were assessed with a generalized linear model and presented in world maps. All evaluations of numbers and rates were calculated per 100,000 population with 95% uncertainty intervals (UIs).

Results
In 2019, the global prevalence of PUD was approximately 8.09 [95% UI 6.79–9.58] million, representing a 25.82% increase from 1990. The age-standardized prevalence rate was 99.40 (83.86–117.55) per 100,000 population in 2019, representing a decrease of 143.37 (120.54–170.25) per 100,000 population from 1990. The age-standardized DALY rate in 2019 was decreased by 60.64% [74.40 (68.96–81.95) per 100,000 population] compared to that in 1990. In both sexes, the numbers and ASRs of the prevalence, incidence, deaths and DALYs were higher in males than in females over 29 years. Regionally, South Asia had the highest age-standardized prevalence rate [156.62 (130.58–187.05) per 100,000 population] in 2019. A low age-standardized death rate was found in the high-income super-region. Among nations, Kiribati had the highest age-standardized prevalence rate [330.32 (286.98–379.81) per 100,000 population]. Regarding socioeconomic status, positive associations between the age-standardized prevalence, incidence, death rate, DALYs and SDI were observed globally in 2019.

Conclusions
Morbidity and mortality due to PUD decreased significantly from 1990 to 2019, while a gradual upward inclination has been observed in recent 15 years, which might be associated with changes in risk factors for PUD. Attention and efforts by healthcare administrators and society are needed for PUD prevention and control.
Graves’ disease overlapping with chronic hepatitis B and methimazole-induced liver injury and autoimmune hepatitis: a case report
Authors: Zheng Meifang , Cui Shiyuan , Zhang Wei , Brigstock David R. , Gao Runping 
Published: February 2022

Abstract
Background
Liver injury related to Graves’ Disease (GD) includes hepatotoxicity of thyroid hormone excess, drug-induced liver injury, and changes resulting from concomitant liver disease. Methimazole (MMI) has been shown to induce several patterns of liver injury. However, the diagnosis and treatment of autoimmune hepatitis (AIH) overlapping with either GD or chronic hepatitis B are challenging.

Case presentation
A 35-year-old man from China presented with a two-year history of GD and a 10-day history of progressive jaundice. He had taken MMI for two months and discontinuing treatment due to liver toxicity 1 year ago and for another 6 days 20 days prior to hospitalization. The patient was diagnosed with GD overlapping with chronic hepatitis B and MMI-induced liver injury with early stage of acute-on-chronic liver failure on admission. However, the elevated aminotransferase and bilirubin levels could not be controlled after correction of liver failure and effective control of HBV replication and hyperthyroidism by daily oral entecavir and one-time oral administration of 131-iodine. The patient underwent liver biopsy on the 43rd day of hospitalization, showing HBsAg expression on the membrane of hepatocytes and typical histopathological characteristics of AIH. He was finally diagnosed with GD overlapping with chronic hepatitis B and MMI-induced liver injury and AIH. The elevated aminotransferase and bilirubin completely returned to normal by 3-month glucocorticoid therapy and continuous entecavir treatment and there was no recurrence during a 6-month follow-up, suggesting that AIH in this patient is different from classical AIH or GD-associated AIH.

Conclusions
GD together with AIH is a complex and difficult subject. It needs to be clarified whether MMI or HBV can act as a trigger for AIH in this patient.

Abstract
Background
In clinical practice, fluctuating vision or decreased quality of vision is a common complaint in DED patients. Our study was designed to investigate the change in dynamic optical quality in dry eye patients after the use of artificial tears.

Methods
Fifty-nine patients with dry eye disease (DED) and 31 control subjects were included in this prospective case-control study. There was no significant difference in age and sex between these two groups (P = 0.342, P = 0.847, respectively). Clinical evaluation of the ocular surface included Ocular Surface Disease Index (OSDI), tear film break-up time (TBUT), lipid layer thickness (LLT), and Schirmer I test. DED patients were divided into two groups, mild (31 patients) and severe (28 patients). The optical quality of the tear film was measured with the Optical Quality Analysis System (OQAS) using the mean objective scatter index (mean OSI), standard deviation of objective scatter index (SD-OSI) and modulation transfer function cut-off (MTF cut-off). After baseline examinations, one drop of artificial tears (ATs, carboxymethylcellulose ophthalmic solution, 0.5%) was instilled in both eyes, and optical quality parameters were measured again at 5 and 30 min following application of ATs.

Results
At baseline, the mean OSI was higher in the DED group (0.95 ± 0.54) than in controls (0.54 ± 0.23, P < 0.001). The SD-OSI was also significantly increased in DED patients (0.44 ± 0.71) compared to control subjects (0.12 ± 0.06, P = 0.003). Five minutes after AT instillation, mean OSI and SD-OSI decreased significantly in severe DED patients (P = 0.044; P = 0.018), remained unchanged in mild DED patients, and increased in the control group (P = 0.019; P < 0.001). Thirty minutes after AT instillation, no significant difference in optical quality parameters was observed among the three groups.

Conclusion
The effect of ATs on optical quality in patients with DED may differ according to the severity of the disease. Measurement of optical quality might be a promising tool to evaluate the effects of various ATs and possibly individualize treatment in DED patients.
