Cardiovascular Health and Disease in the Context of COVID-19.

First documented in China in early December 2019, the novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) spread rapidly and continues to test the strength of healthcare systems and public health programs all over the world. Underlying cardiovascular disease has been recognized as a risk factor for coronavirus disease 2019 (COVID-19)-related morbidity and mortality since the early days of the pandemic. In addition, evidence demonstrates cardiac and endothelial damage in somewhere between one-third and three-quarters of individuals with COVID-19, regardless of symptom severity.

Management of No-Reflow Phenomenon in the Catheterization Laboratory.

At the conclusion of a primary percutaneous coronary intervention for ST-segment elevation myocardial infarction, and after the cardiologist makes certain that there is no residual stenosis following stenting, assessment of coronary flow becomes the top priority. The presence of no-reflow is a serious prognostic sign. No-reflow can result in poor healing of the infarct and adverse left ventricular remodeling, increasing the risk for major adverse cardiac events, including congestive heart failure and death.

Adverse Childhood Experiences and Health in Adulthood in a Rural Population-Based Sample.

Background: Adverse childhood experiences (ACEs), including emotional abuse, substance abuse in the household, separation or divorce, physical abuse, violence between adults, mental illness in the household, sexual abuse, or incarceration of a household member, have the potential to profoundly impact health and well-being in adulthood. To assess whether previously reported relationships between ACEs and health outcomes withstand validation, we conducted a community-based ACE study with the unique capacity to link self-reported ACEs and other survey results to validated health data in an electronic medical record (EMR).

Methods: Information regarding ACEs and health outcomes was captured from 2013-2014 via a telephone survey of residents of the predominantly rural northern and central regions of Wisconsin and electronic abstraction of EMR data.

The McGill Brisbane Symptom Score in relation to survival in pancreatic adenocarcinoma: a validation study.

Purpose: The McGill Brisbane Symptom Score (MBSS) is a clinical score for pancreatic cancer patients upon initial presentation that takes into account four variables (weight loss, abdominal pain, jaundice, and history of smoking) to stratify them into two MBSS intensity categories. Several studies have suggested that these categories are strongly associated with eventual survival in patients with resectable (rPCa) and unresectable (uPCa) pancreatic cancer. This study aimed to validate the MBSS in a cohort of patients with pancreatic cancer from a single institution.

All-cause mortality is decreased in women undergoing annual mammography before breast cancer diagnosis.

Objective: The value of annual mammography remains an area of debate because of concerns regarding risk versus benefit. The potential for harm due to overdiagnosis and treatment of clinically insignificant cancers may not be captured by breast cancer-specific mortality. Instead, we examined all-cause mortality as a function of missed annual mammography examinations before breast cancer diagnosis.

Cardiovascular consequences of cocaine use.

The cardiovascular consequences of cocaine use are numerous and can be severe, with mechanisms of cardiotoxicity unique to cocaine that include sympathomimetic effects, blockade of sodium and potassium channels, oxidative stress and mitochondrial damage, and disruption of excitation-contraction coupling. In combination, these effects increase myocardial oxygen demand while simultaneously decreasing oxygen supply. Cocaine-associated chest pain is particularly common and, in some instances, associated with a more severe cardiac syndrome, such as myocardial infarction, myocardial ischemia, arrhythmia, cardiomyopathy, aortic dissection, or endocarditis.

Survival Comparisons for Breast Conserving Surgery and Mastectomy Revisited: Community Experience and the Role of Radiation Therapy.

Objectives: Evidence suggests superiority of breast conserving surgery (BCS) plus radiation over mastectomy alone for treatment of early stage breast cancer. Whether the superiority of BCS plus radiation is related to the surgical approach itself or to the addition of adjuvant radiation therapy following BCS remains unclear.

Materials And Methods: We conducted a retrospective cohort study of women with breast cancer diagnosed from 1994-2012.

Cardiovascular toxicity associated with adjuvant trastuzumab therapy: prevalence, patient characteristics, and risk factors.

Before the advent of the human epidermal growth factor receptor 2 (HER2)-targeted monoclonal antibody trastuzumab, HER2-positive breast cancers were difficult to treat and had a poor prognosis. Adjuvant trastuzumab is now an important part of the treatment regimen for many women with HER2-positive breast cancer and has undoubtedly resulted in a significant improvement in prognosis, but it is associated with a risk for cardiotoxicity. In this review, we describe the prevalence, patient characteristics, and risk factors for cardiotoxicity associated with use of adjuvant trastuzumab.

Geographical and seasonal barriers to mammography services and breast cancer stage at diagnosis.

Introduction: Routine mammography screening and early detection are important prognostic indicators for breast cancer. Geographical and seasonal barriers to mammography services and relationship to breast cancer stage at diagnosis were examined.

Methods: Travel time to mammography center, seasonal distribution of mammogram use, mammography frequency, and stage of cancer were retrospectively examined in 1428 female patients diagnosed with primary breast cancer at a tertiary care clinic system in Wisconsin, USA, from 2002 to 2008.

A novel method for studying the temporal relationship between type 2 diabetes mellitus and cancer using the electronic medical record.

Background: We developed an algorithm for the identification of patients with type 2 diabetes and ascertainment of the date of diabetes onset for examination of the temporal relationship between diabetes and cancer using data in the electronic medical record (EMR).

Methods: The Marshfield Clinic EMR was searched for patients who developed type 2 diabetes between January 1, 1995 and December 31, 2009 using a combination of diagnostic codes and laboratory data. Subjects without diabetes were also identified and matched to subjects with diabetes by age, gender, smoking history, residence, and date of diabetes onset/reference date.

Breast cancer biomarkers: risk assessment, diagnosis, prognosis, prediction of treatment efficacy and toxicity, and recurrence.

Breast cancer is the most common cancer amongst women in the United States and around the world. Although widespread use of adjuvant chemotherapeutic and hormonal agents has improved mortality from breast cancer, it remains challenging to determine on an individual basis who will benefit from such treatments and who will be likely to encounter toxicities. With the rising costs of healthcare and the introduction of new targeted therapies, use of biomarkers has emerged as a method of assisting with breast cancer diagnosis, prognosis, prediction of therapeutic response, and surveillance of disease during and after treatment.

A core-item reviewer evaluation (CoRE) system for manuscript peer review.

Manuscript peer review is essential for ensuring accountability to all involved in the publication process, including authors, journals, and readers. Lack of consensus regarding what constitutes an accountable manuscript peer review process has resulted in varying practices from one journal to the next. Currently, reviewers are asked to make global judgments about various aspects of a paper for review irrespective of whether guided by a review checklist or not, and several studies have documented gross disagreement between reviewers of the same manuscript.

Type 2 diabetes mellitus, glycemic control, and cancer risk.

Type 2 diabetes mellitus is characterized by prolonged hyperinsulinemia, insulin resistance, and progressive hyperglycemia. Disease management relies on glycemic control through diet, exercise, and pharmacological intervention. The goal of the present study was to examine the effects of glycemic control and the use of glucose-lowering medication on the risk of breast, prostate, and colon cancer.

Mammography utilization: patient characteristics and breast cancer stage at diagnosis.

Objective: Missed mammograms represent missed opportunities for earlier breast cancer diagnosis. The purposes of this study were to identify patient characteristics associated with missed mammograms and to examine the association between missed mammograms and breast cancer stage at diagnosis.

Materials And Methods: Mammography frequency and cancer stage were retrospectively examined in 1368 cases of primary breast cancer diagnosed at our clinic from 2002 to 2008.

Increased risk of colon cancer in men in the pre-diabetes phase.

Background: Historically, studies exploring the association between type 2 diabetes mellitus (DM) and cancer lack accurate definition of date of DM onset, limiting temporal analyses. We examined the temporal relationship between colon cancer risk and DM using an electronic algorithm and clinical, administrative, and laboratory data to pinpoint date of DM onset.

Methods: Subjects diagnosed with DM (N = 11,236) between January 1, 1995 and December 31, 2009 were identified and matched at a 5∶1 ratio with 54 365 non-diabetic subjects by age, gender, smoking history, residence, and diagnosis reference date.

Reliability of reviewer ratings in the manuscript peer review process: an opportunity for improvement.

Accountability to authors and readers cannot exist without proper peer review practices. Thus, the information a journal seeks from its peer reviewers and how it makes use of this information is paramount. Disagreement amongst peer reviewers can be considerable, resulting in very diverse comments to authors.

Breast and prostate cancer survivors in a diabetic cohort: results from the Living with Diabetes Study.

Objective: Diabetes is more common in cancer survivors than in the general population. The objective of the present study was to determine cancer frequency in a cohort of patients with diabetes and to examine demographic, clinical, and quality of life differences between cancer survivors and their cancer-free peers to inform better individualized care.

Methods: Self-reported survey data from 3,466 registrants with type 2 diabetes from Australia's National Diabetes Services Scheme (NDSS) were analyzed to compare relevant variables between cancer survivors and cancer-free patients.

Prostate cancer risk in pre-diabetic men: a matched cohort study.

Background: Diagnosis and duration of type 2 diabetes mellitus (DM) appear to be associated with decreased prostate cancer risk. Limitations of previous studies include methods of subject selection and accurate definition of DM diagnosis. We examined the temporal relationship between DM and prostate cancer risk exploring the period of greatest risk starting from the prediabetic to the post-diabetic period using clinical and administrative data to accurately define the date of DM diagnosis.

Adequate lymph node recovery improves survival in colorectal cancer patients.

Introduction: Current recommendations suggest recovery of 12 lymph nodes during surgical resection for colorectal cancer (CRC) for proper staging and prognostication. Adequate lymph node recovery has been associated with improved patient survival, with results inconsistent.

Methods: We examined factors for association with adequate lymph node recovery and used findings to adjust survival analyses to clarify whether adequate lymph node examination is associated with CRC survival or associated with a subset of characteristics that biases lymph node recovery.

Breast cancer incidence before and after diagnosis of type 2 diabetes mellitus in women: increased risk in the prediabetes phase.

The physiological changes associated with type 2 diabetes mellitus begin before disease onset, yet few have examined the incidence of cancer both before and after diabetes onset. We examined the temporal relationship between diabetes and breast cancer risk. Breast cancer risk was assessed in a retrospective cohort study using patient data from the Marshfield Clinic electronic medical record including 5423 women who developed diabetes between 1 January 1995 and 31 December 2009 (reference date) and 26 346 nondiabetic women matched by age, smoking history, residence, and reference date.

Diabetes and cancer I: risk, survival, and implications for screening.

Type 2 diabetes mellitus (DM) and cancer are common diseases that are frequently diagnosed in the same individual. An association between the two conditions has long been postulated. Here, we review the epidemiological evidence for increased risk of cancer, decreased cancer survival, and decreased rates of cancer screening in diabetic patients.

Diabetes and cancer II: role of diabetes medications and influence of shared risk factors.

An association between type 2 diabetes mellitus (DM) and cancer has long been postulated, but the biological mechanism responsible for this association has not been defined. In part one of this review, we discussed the epidemiological evidence for increased risk of cancer, decreased cancer survival, and decreased rates of cancer screening in diabetic patients. Here we review the risk factors shared by cancer and DM and how DM medications play a role in altering cancer risk.

High-sensitivity C-reactive protein (hs-CRP) as a biomarker for trastuzumab-induced cardiotoxicity in HER2-positive early-stage breast cancer: a pilot study.

Monitoring of left ventricular ejection fraction (LVEF) is the current standard for detection of trastuzumab-induced cardiotoxicity; however, time-to-diagnosis and cost of assessment are suboptimal in women with early-stage breast cancer. We assessed the utility of B-type natriuretic peptide (BNP), high-sensitivity C-reactive protein (hs-CRP), and cardiac troponin I (cTnI) as serum biomarkers for early detection of trastuzumab-induced cardiotoxicity. Fifty-four women with human epidermal growth factor receptor 2 (HER2)-positive early-stage breast cancer were prospectively enrolled, and the relationship between elevated serum BNP, hs-CRP, and cTnI levels and clinically significant decreases in LVEF was examined.
