Quantitative Evaluation of Type 1 and Type 2 Choroidal Neovascularization Components Under Treatment With Projection-Resolved OCT Angiography.

Purpose: To evaluate the response of type 1 and type 2 macular neovascularization (MNV) components under anti-vascular endothelial growth factor (VEGF) treatment in age-related macular degeneration (AMD) using projection-resolved optical coherence tomography angiography (PR-OCTA). Methods: This retrospective study included eyes with treatment-naïve exudative AMD treated with anti-VEGF injections under a pro re nata (PRN) protocol over 1 year. Two-dimensional MNV areas and three-dimensional MNV volumes were derived from macular PR-OCTA scans using an automated convolutional neural network. MNV was detected as flow signal within the outer retinal slab. Type 1 components and type 2 components were analyzed separately. Results: Of 17 enrolled eyes, 12 eyes were pure type 1 MNV and five eyes were type 2 MNV. In eyes with pure type 1, the total (sum of type 1 and type 2 components) MNV area and volume did not change from baseline to 6 months or 12 months (P > 0.05). In eyes with type 2 MNV, the total MNV area significantly decreased from the baseline to 6 months (P = 0.0074) and 12 months (P = 0.014). The total type 2 MNV volume also decreased from baseline visit to visits at 6 months and at 12 months, nearing statistical signifiicance (P = 0.061 and P = 0.074). In eyes with type 2 MNV, the type 1 component increased from 0.093 mm2 to 0.30 mm2 (P = 0.058), and the type 2 component decreased from 0.37 mm2 at 6 months to 0 at 12 months (P = 0.0087). Conclusions: Type 1 and type 2 MNV may have different response under PRN anti-VEGF treatment over 1 year.

Overtreatment and Undertreatment of Early-Stage Breast Cancer in Older Women: Evaluating the POWER Trial.

INTRODUCTION: Radiation therapy (RT) omission is acceptable in older women with early-stage estrogen receptor + breast cancer treated with breast-conserving surgery (BCS) and adjuvant endocrine therapy (AET). However, RT rates in this population remain high, causing concern for overtreatment. Conversely, patients who omit RT and do not complete a course of AET are at risk of undertreatment. In the Pre-Operative Window of Endocrine Therapy to Inform Radiation Therapy Decisions (POWER) trial, participants receive 90 days of preoperative endocrine therapy to assess tolerance before deciding about RT. This study aimed to determine the rates of undertreatment and overtreatment institutionally and among POWER trial participants. METHODS: Data were retrospectively collected from medical records of women aged ≥ 65 years diagnosed with invasive, estrogen receptor +/human epidermal growth factor receptor 2- breast cancer, ≤ 3 cm, who had BCS between 2012 and 2022. Patients were categorized as undertreated (BCS alone), overtreated (BCS + RT + AET), or appropriately treated (BCS + RT or BCS + AET). RESULTS: The cohort included 478 patients, of whom 62 (12.97%) were undertreated, 202 (42.26%) were overtreated, and 214 (44.77%) were appropriately treated. Appropriately treated patients were more likely to be aged 70-79 years (P < 0.0001) and have high health literacy (P = 0.0003). Of the 37 patients (7.71%) in the POWER trial, more were appropriately treated than patients not in the POWER trial (81.1% versus 44.8%) (P < 0.0001). CONCLUSIONS: Despite long-standing guideline changes, RT utilization remains high. This study highlights how a novel patient-centered approach to guide adjuvant therapy decisions may increase the number of appropriately treated patients.

Underdiagnosis, Undertreatment, and Noncompliance With Treatment in People Who Died by Suicide.

Background: This study explored the characteristics of people who die by suicide, comparing those who had depression with those who did not.Methods: Clinical data were collected through a postmortem proxy-based semistructured interview (psychological autopsy). Postmortem toxicological analysis provides data on the presence of substances or drugs in the blood of suicides. Participants were adults who died by suicide in the province of Seville, Spain, during 2006-2016. The main independent variables were previous diagnosis, postmortem diagnosis, prescribed treatment, and treatment found in blood. The primary outcome was the postmortem diagnosis of depression, after which the sample was divided into 2 groups according to DSM IV criteria to the presence or absence of major depressive episode (MDE).Results: Our sample is composed of 313 people, of which 200 (63.9%) had a diagnosis of MDE according to the psychological autopsy. Predeath diagnosis of depression was more frequent in MDE suicides than in non-MDE suicides (18.6% vs 3.5%, respectively; Χ2 = 23.420; df = 9; P = .005) and had more access to mental health treatment previous to death (67.7% vs 35.6%, respectively; Χ2 = 27.572; df = 1; P < .001). Antidepressants were prescribed in 21.5% of the MDE suicides, but only 8.5% of them were taking them at the time of death according to the toxicology exam.Conclusions: The underdiagnosis of depression in people who die by suicide is striking, as is the undertreatment. Further efforts must be made to train primary care physicians in the proper identification of persons at risk of suicide, as they are one of the main gatekeepers in the fight for suicide prevention.

Vertebral compression fractures at abdominal CT: underdiagnosis, undertreatment, and evaluation of an AI algorithm.

Vertebral compression fractures (VCFs) are common and indicate a high future risk of additional osteoporotic fractures. However, many VCFs are unreported by radiologists, and even if reported, many patients do not receive treatment. The purpose of the study was to evaluate a new artificial intelligence (AI) algorithm for the detection of VCFs and to assess the prevalence of reported and unreported VCFs. This retrospective cohort study included patients over age 60 yr with an abdominal CT between January 18, 2019 and January 18, 2020. Images and radiology reports were reviewed to identify reported and unreported VCFs, and the images were processed by an AI algorithm. For reported VCFs, the electronic health records were reviewed regarding subsequent osteoporosis screening and treatment. Totally, 1112 patients were included. Of these, 187 patients (16.8%) had a VCF, of which 62 had an incident VCF and 49 had a previously unknown prevalent VCF. The radiologist reporting rate of these VCFs was 30% (33/111). For moderate and severe (grade 2-3) VCF, the AI algorithm had 85.2% sensitivity, 92.3% specificity, 57.8% positive predictive value, and 98.1% negative predictive value. Three of 30 patients with reported VCFs started osteoporosis treatment within a year. The AI algorithm had high accuracy for the detection of VCFs and could be very useful in increasing the detection rate of VCFs, as there was a substantial underdiagnosis of VCFs. However, as undertreatment in reported cases was substantial, to fully realize the potential of AI, changes to the management pathway outside of the radiology department are imperative.

Vertebral compression fractures (VCFs) are the most common osteoporotic fractures. However, they often go undetected leading to a high risk of further fractures. In this study, we tested a new artificial intelligence (AI) algorithm to detect VCFs in abdominal CT scans in patients over 60 yr of age and assessed how often VCFs were missed by radiologists. We found that VCFs were underreported, with only 30% being identified by the radiologists. The AI algorithm showed promising results and had high accuracy for detecting VCFs. However, many patients with a detected VCF still did not receive treatment. The results suggest that AI could increase the detection rate of VCFs, but also highlight the need for changes beyond radiology to ensure that patients with detected fractures are appropriately treated.

Ductal carcinoma in situ of the breast: finding the balance between overtreatment and undertreatment.

Ductal carcinoma in situ (DCIS) accounts for 15-25% of all breast cancer diagnoses. Its prognosis is excellent overall, the main risk being the occurrence of local breast events, as most cases of DCIS do not progress to invasive cancer. Systematic screening has greatly increased the incidence of this non-obligate precursor of invasion, lending urgency to the need to identify DCIS that is prone to invasive progression and distinguish it from non-invasion-prone DCIS, as the latter can be overdiagnosed and therefore overtreated. Treatment strategies, including surgery, radiotherapy, and optional endocrine therapy, decrease the risk of local events, but have no effect on survival outcomes. Active surveillance is being evaluated as a possible new option for low-risk DCIS. Considerable efforts to decipher the biology of DCIS have led to a better understanding of the factors that determine its variable natural history. Given this variability, shared decision making regarding optimal, personalised treatment strategies is the most appropriate course of action. Well designed, risk-based de-escalation studies remain a major need in this field.

Patient and Care Partner Perspective on Potential Undertreatment of Patients With Mild Cognitive Impairment for Cardiovascular Disease.

BACKGROUND AND OBJECTIVES: Mild cognitive impairment (MCI) affects up to 22% of US older adults aged 65 and older. Research suggests that physicians may recommend less cardiovascular disease (CVD) treatment for older adults with MCI due to assumptions about their preferences. To delve into the disparity between patient preferences and physician assumptions in CVD treatment recommendations, we conducted a multi-site qualitative study to explore the underlying reasons for this discrepancy, providing insights into potential communication barriers and strategies to enhance patient-physician relationships. RESEARCH DESIGN AND METHODS: Employing a descriptive qualitative approach, we conducted interviews with 20 dyads, comprising older adults with MCI (n = 11) and normal cognition NC (n = 9), and their respective care partners. During these interviews, participants were prompted to reflect on physicians recommending fewer guideline-concordant CVD treatments to older adults with MCI than those with NC and physicians presuming that older adults with MCI desired less care or treatment in general than those with NC. RESULTS: We identified three primary themes: (1) Most participants had negative reactions to the data that physicians might undertreat patients with MCI for CVD; (2) Participants suggested that physicians may undertreat patients with MCI due to physician assumptions about treatment effectiveness, patient prognosis, value, and treatment adherence, and (3) Participants proposed that physicians may elicit less input from patients with MCI about treatments because of negative physician assumptions about patient decision-making capacity and physician time limitations. DISCUSSION AND IMPLICATIONS: This study underscores the pressing need for person-centered communication and involvement of older adults with MCI and their care partners in the decision-making process to ensure that decisions are well-informed, reflecting patients' genuine preferences and values. Addressing these concerns has the potential to substantially enhance the quality of care and treatment outcomes for this vulnerable population, ultimately promoting their overall well-being.

Uncovering risk factors for adverse events and infections in rheumatoid arthritis and rheumatoid arthritis with interstitial lung disease under treatment with biologics or targeted synthetic DMARDs: insights from the KOBIO Registry.

OBJECTIVES: This study aimed to identify the risk factors associated with overall adverse events (AEs) and infections in patients with rheumatoid arthritis (RA) and comorbid interstitial lung disease (ILD), receiving biologic or targeted synthetic disease-modifying anti-rheumatic drugs (b/tsDMARDs), using data from the Korean College of Rheumatology Biologics registry. METHODS: We analysed data from a cohort of 2,266 adult patients with RA who received b/tsDMARDs, including 169 patients with comorbid ILD. We identified the risk factors for overall AEs and infections in both the all RA group and the subgroup of patients with RA-ILD and investigated the impact of infections on mortality in patients with RA-ILD. RESULTS: Among all patients with RA, 45.7% withdrew b/tsDMARDs, whereas among those with RA-ILD, a higher proportion of 57.4% withdrew their treatment regimen. The main reason for withdrawing b/tsDMARDs in the RA-ILD group was AEs, with infections accounting for the largest proportion of reported AEs. In multivariable analysis of the risk factors for overall AEs and infections in the RA-ILD group, older age was identified as a risk factor for overall AEs (odds ratio [OR], 3.01; p=0.014), and only a current smoking status was identified as a risk factor for infections (OR, 2.11; p=0.035). CONCLUSIONS: Patients with RA-ILD exhibited a higher rate of b/tsDMARDs withdrawal due to overall AEs and infections than those with RA without ILD. In the RA-ILD group, older age was identified as a risk factor for overall AEs, whereas a current smoking status was identified as a risk factor for infections.

What are the consequences of over and undertreatment of type 2 diabetes mellitus in a frail population? A systematic review.

AIMS: This review aims to identify the evidence base for the consequences of over and undertreatment of type 2 diabetes mellitus in a frail population. METHOD: In this systematic review, we searched MEDLINE, Embase, PubMed, CINAHL and the Cochrane Library for studies from January 2001 to 15th August 2022. We included a variety of study types that assessed and reported frailty including patients ≥18 years old. Studies included those that reported the prevalence of over or undertreatment of diabetes mellitus in a frail population and those examining outcomes related to glucose control in frail older people living with diabetes. Data were extracted using a bespoke extraction table using a narrative synthesis approach. RESULTS: A total of 4114 articles were identified with 112 meeting inclusion criteria. These included 15,130 participants across the 11 studies with sample sizes ranging from 101 to 11,140. Several areas were identified in the included studies where under or overtreatment of diabetes impacted outcomes for patients. These included hospital admissions, readmissions, length of stay, falls, mortality, cognitive impairment and cardiovascular disease outcomes. CONCLUSION: The results showed that there was a high heterogeneity of outcomes between the studies and that many examined small numbers of participants. In this review, both over and undertreatment were shown to increase adverse outcomes in frail older people. Further research around optimal glycaemic control for frail older people living with diabetes is required with the aim to identify ideal target ranges and produce practical clinical guidelines to promote attainment of these.

Trends in pain undertreatment among lung cancer patients at the EOL: Analysis of urban city medical insurance data in China.

BACKGROUND: Cancer-related pain is one of the common priority symptoms in advanced lung cancer patients at the end-of-life (EOL). Alleviating pain is undoubtedly a critical component of palliative care in lung cancer. Our study was initiated to examined trends in opioid prescription-level outcomes as potential indicators of undertreated pain in China. METHODS: This study used data on 1330 patients diagnosed with lung cancer of urban city medical insurance in China who died between 2014 and 2017. Opioid prescription-level outcomes were determined by annual trends of the proportion of patients filling an opioid prescription, the total dose of opioids filled by decedents, and morphine milligram equivalents per day (MMED) at the EOL (defined as the 60 days before death). We further analyzed monthly changes in the number of opioid prescriptions filled, MMED, and mean daily dose of opioids per prescription (MDDP) of the last 60 days of life by year at death and age, respectively. RESULTS: A total of 959 patients with exact dates of death were included, with 432 cases (45.06%; 95% CI: 44.36%-45.77%) receiving at least one opioid prescription at the EOL. The declining trends were shown in the proportion of patients filling any opioid prescription, the total dose of opioids filled by decedents and MMED, with an annual decrease of 0.341% (p = 0.01), 104.23 mg (p = 0.011) and 2.84 mg (p = 0.014), respectively. Within the 31-60 days to the 0-30 days of life, the MMED declined 6.08 mg (95% CI: -7.14 to -5.03; p = 0.000351), while the number of opioid prescriptions rose 0.66 (95% CI: 0.160-1.16; p = 0.025). Like the MMED, the MDDP fell 4.11 mg (95% CI: -5.86 to -2.37; p = 0.005) within the last month before death compared to the previous month. CONCLUSION: Terminal lung cancer populations in urban China have experienced reduced access to opioids at the EOL. The clinicians did not prescribe a satisfactory dose of opioids per prescription, while the patients suffered increasing pain in the last 30 days of life. Sufficient opioid analgesic administration should be advocated for lung cancer patients during the EOL period.

Prevalence of atrial fibrillation and reasons for undertreatment with oral anticoagulants.

OBJECTIVES: To investigate the prevalence of atrial fibrillation (AF), the proportion of AF patients not receiving oral anticoagulation (OAC) and reasons for abstaining from OAC treatment. METHODS: A retrospective cross-sectional study of patients aged 18 years or older with an AF diagnosis on June 1st 2020 in Västernorrland County, Sweden. AF diagnosis was retrieved using the ICD10 code I.48, and medical records were reviewed for comorbidities and documented reasons to abstain OAC treatment. RESULTS: Of 197 274 residents in Västernorrland County, 4.7% (9 304/197 274) had a documented AF diagnosis. Of these, 19% (1 768/9 304) had no OAC treatment, including 4.2% (393/9 304) with no indication, 2.5% (233/9 304) with a questionable and 2.5% (231/9 304) with a documented clear contraindication for OAC. In total 9.8% (911/9 304) were not treated with OAC despite indication and no reasonable documented contraindication, thus 90.8% (8 447/9 304) of all AF-patients were eligible for OAC treatment. Common reasons for abstaining treatment without reasonable contraindication were present sinus rhythm in 13.7% (125/911), perceived not an OAC candidate in 10.6% (97/911) and anemia in the past in 4.3% (39/911). CONCLUSIONS: In the population of Västernorrland County, a very high AF prevalence of 4.7% was found, of which just over 90% would theoretically benefit from OAC treatment. This is higher than previously reported and stresses the importance of stroke prevention in this large patient group.

Risk factors for oral mucositis in patients with solid tumors under treatment with cetuximab: a retrospective cross-sectional study.

BACKGROUND: This study retrospectively analyzed the risk factors for oral mucositis (OM) during cetuximab treatment. MATERIAL AND METHODS: We screened patients using cetuximab and retrospectively evaluated the presence of OM based on medical records. We collected information from 2 years of evaluations. Patient medical records were reviewed to obtain data on chemotherapy cycle and dose, sex, age, primary tumor, TNM stage, and head and neck radiotherapy (HNR) history. The X2 test and multinomial logistic regression were used for statistical analysis (SPSS 20.0, p < 0.05). RESULTS: Among 1831 patients, OM was showed in 750 in any grade (41%), during cetuximab treatment. Most patients were female (n=944, 51.6%), <70years-old (n=1149, 62.8%), had larynx cancer (n=789, 43.1%) in T4 (n=579, 47.7%), N0 (n=509, 52.6%) stages. Primary tumor surgery was performed in 1476 (80.6%) patients, radiotherapy in 606 (33.1%) patients and cetuximab protocols most used involved up to four cycles (n=1072, 58.5%) of <400mg (n=996, 54.4%) cetuximab doses. Female (OR [odds ratio] = 2.17, CI95% = 1.26-3.75), >70 years-old patients (OR = 16.02, CI95% = 11.99-21.41), with HHNR (OR = 1.84, 1.41-2.40), treated with >4 cycles (OR = 1.52, CI95% = 1.16-2.01) and high doses of cetuximab (OR = 3.80, CI95% = 2.52-5.71) are the greatest risk factors for OM. CONCLUSIONS: Since the clinical benefit of cetuximab in the treatment of older patients is limited and there is a high OM, especially in women with head and neck treated with radiotherapy, high doses and a high number of cetuximab cycles must be administered with caution.

Insuficiente aplicación de Medicina Natural y Tradicional en afecciones relacionadas con la ortopedia y la traumatología / Unsatisfactory Application of Natural and Traditional Medicine in Conditions Related with Orthopedics and Traumatology

La Medicina Natural y Tradicional aplica sus diferentes modalidades en la práctica médica moderna, segura, económica, inocua y simple; y con pocos efectos colaterales resuelve grandes problemas de salud en situaciones especiales o de desastres con recursos limitados. De ahí que el egresado de programas de especialización de las ciencias médicas cuenta con sólidos conocimientos para su aplicación, especialmente en las afecciones osteomioarticulares, donde la especialidad de ortopedia y traumatología tiene un papel primordial para identificar las causas y consecuencias de la insuficiencia de su aplicación en pacientes portadores de afecciones relacionadas con esta especialidad. A través de un estudio crítico reflexivo basado en el análisis y la síntesis, así como de la constatación de la validez de los puntos de vista asumidos como referentes en el proceso de superación del especialista de ortopedia y traumatología, se pudo mostrar cómo se ha concebido la superación profesional en el Hospital General Dr. Juan Bruno Zayas Alfonso, al integrar adecuadamente los conocimientos y las competencias. Esto se expresó en la elaboración e implementación de una estrategia de superación profesional, que permitió la actualización de relevantes conocimientos necesarios en el campo de la MNT para el desempeño de este profesional. Se concluyó que era insuficiente el nivel de conocimiento de los contenidos, como también los cursos ofertados para su desarrollo, lo que trajo como consecuencia una atención médica sin calidad(AU)

Natural and traditional medicine applies its different modalities in modern, safe, economical, innocuous and simple medical practice; with few collateral effects, it solves major health problems in special or disaster situations with limited resources. Hence, the graduate of specialization programs in medical sciences possesses solid knowledge for its application, especially in osteomyoarticular conditions, in which the specialty of orthopedics and traumatology has a key role in identifying the causes and consequences of its unsatisfactory application in patients with conditions related to this specialty. Through a reflexive and critical study based on analysis and synthesis, as well as the verification of the validity of the viewpoints assumed as referents in the process of improvement of the orthopedics and traumatology specialist, it was possible to show how professional improvement has been conceived at Hospital General Dr. Juan Bruno Zayas Alfonso, by adequately integrating knowledge and competences. This was expressed through the elaboration and implementation of a professional improvement strategy, which allowed updating relevant knowledge necessary in the field of natural and traditional medicine for the performance of this professional. The level of knowledge about the contents was concluded to be insufficient, while the courses offered for its development were so, which resulted in a medical care without quality(AU)
