A shave biopsy of the lesion confirmed a nodular and pigmented basal cell carcinoma (BCC). In the United States, BCC is the most common cancer and accounts for 80% of all skin cancer diagnoses. BCC is also the most widespread cancer in White, Hispanic, and Asian patients and the second most common skin cancer in Black patients.

In all patients, BCC presents as a shiny growing macule, papule, or plaque, usually in areas of sun exposure. Much less is known about the role of UV exposure in skin of color because of the lack of high-quality studies in this population. Despite this, BCC in skin of color most often presents on the head and neck, as it does in non-Hispanic White patients. There is a correlation between lighter skin tones in Black patients and increased numbers of BCC diagnoses.

When assessing a suspicious skin lesion in skin of color, be on the lookout for the following visual cues. Pigmentation, clinically and on dermoscopy, is a more common feature of BCCs in non-White patients—occurring in more than half of all BCCs in skin of color.¹ While pigmentation in a skin tumor may be mistaken for melanoma, the blue ovoid nests, brown dots in focus, and brown leaf-like areas on dermoscopy are BCC-specific clues that can alert the clinician to the diagnosis. In all patients, telangiectasias are another hallmark of BCC but may be the only feature in White patients and just one of many features in non-White patients.

In small data sets, there is no difference in tumor-related morbidity and prognosis between White and Black patients with BCC. Additionally, BCCs in White, Asian, and Hispanic patients have had no differences in preoperative tumor size, number of Mohs stages, and outcome.¹

In this case, the patient underwent a complete excision with a 5-mm margin. She remained free of new or recurrent BCCs over the next 2 years, with surveillance exams twice a year.

Maintaining an average hydroxychloroquine whole blood level above 1,068 ng/mL significantly reduced the risk of thrombosis in adults with systemic lupus erythematosus, based on data from 739 patients.

Hydroxychloroquine (HCQ) is a common treatment for systemic lupus erythematosus (SLE); studies suggest that it may protect against thrombosis, but the optimal dosing for this purpose remains unknown, wrote Michelle Petri, MD, of Johns Hopkins University, Baltimore, and colleagues. In a study published in Arthritis & Rheumatology, the researchers examined data on HCQ levels from 739 adults with SLE who were part of the Hopkins Lupus Cohort, a longitudinal study of outcomes in SLE patients. Of these, 38 (5.1%) developed thrombosis during 2,330 person-years of follow-up.

The average age of the patients at the time HCQ measurements began was 43 years, 93% were female, and 46% were White. Patients visited a clinic every 3 months, and HCQ levels were determined by liquid chromatography-tandem mass spectrometry.

“Between-person and within-person correlation coefficients were used to measure the strength of the linear association between HCQ blood levels and commonly prescribed HCQ doses from 4.5 to 6.5 mg/kg,” the researchers said.

Higher doses of HCQ have been associated with increased risk for retinopathy, and current guidelines recommend using less than 5 mg/kg of ideal body weight, the researchers said. “Importantly, there was no correlation between the prescribed dose and the hydroxychloroquine blood level over the range (4.5 to 6.5 mg/kg) used in clinical practice, highlighting the need for personalized hydroxychloroquine drug level-guided therapy and dose adjustment,” they emphasized.

The study findings were limited by several factors, including the observational design and potential confounding from variables not included in the model, as well as the small sample size, single site, and single rheumatologist involved in the study, the researchers noted.

The results suggest that aiming for a blood HCQ level of 1,068 ng/mL can be done safely to help prevent thrombosis in patients with SLE, the researchers said. “Routine clinical integration of hydroxychloroquine blood level measurement offers an opportunity for personalized drug dosing and risk management beyond rigid empirical dosing recommendations in patients with SLE,” they concluded.

The study was supported in part by grants from the National Institutes of Health and the National Institute of Arthritis and Musculoskeletal and Skin Diseases. The researchers had no relevant financial conflicts to disclose.

Key clinical point: A simplified system based on four clinical parameters of the flow cytometric score (MFCM-Score) was positively correlated with the Revised International Prognostic Scoring System (IPSS-R) for myelodysplastic syndrome.

Major finding: No significant difference appeared between the MFCM-score and FCM-score in diagnosing myelodysplastic syndrome (P > 0.05).

Study details: The data come from 118 adults with suspected myelodysplastic syndrome. Patients were compared using the FCM and MFCM. Four parameters were used in the standard FCM scoring: myeloblast-related cluster size (myeloblast-related cells/all nucleated cell), B-progenitor-related cluster size (B-progenitor-related cells/all CD34⁺ cells), CD45 mean fluorescence intensity (MFI) ratio (lymphocytes/myeloid blast cells), and SSC peak channel ratio (granulocyte/lymphocyte). The MFCM simplified the scoring further by using CD19 and CD33 to separate B lymphocyte progenitor cells and myeloblasts within the CD34⁺CD45^dimm population.

Yet another study has linked the consumption of ultraprocessed, or “junk,” foods to bad health outcomes.

In a longitudinal analysis of more than 22,000 men and women from southern Italy, those who consumed the most ultraprocessed food (UPF) had the highest risk for cardiovascular disease (CVD) and all-cause mortality, likely mediated through a diet high in sugar, researchers said.

High consumption of UPF in this Mediterranean cohort was associated with a 58% increased risk for CVD mortality and 52% higher risk of dying from ischemic heart disease (IHD) and cerebrovascular causes, independently of known risk factors for CVD, even among individuals who otherwise adhered to the Mediterranean diet.

The findings “should serve as an incentive for limiting consumption of UPF and encouraging natural or minimally processed foods, as several national nutritional policies recommend,” Marialaura Bonaccio, PhD, department of epidemiology and prevention, IRCCS Neuromed, Pozzilli, Italy, and colleagues wrote. The results were published online Dec. 18 in the American Journal of Clinical Nutrition.

Earlier this year, as reported by this news organization, researchers found mounting evidence that the obesity epidemic and the increase in incidence of related chronic conditions corresponded with an increase in the intake of UPF.

A study that was conducted in a European cohort found that adults whose diet included more UPF and beverages, such as ice cream, soda, and hamburgers, were more likely to develop CVD or die sooner than others who had a more wholesome diet.

As reported previously by this news organization, among adults in France who had a 10% higher intake of UPF and beverages, the rate of CVD, coronary heart disease, and cerebrovascular disease was 11% to 13% higher over a period of about 5 years.

Similarly, university graduates in Spain who consumed more than four servings of UPF and beverages a day were 62% more likely to die of any cause over about a decade than those who consumed less than two servings per day.
 

Where’s the food?

There is very little actual food in UPF. “The NOVA classification provides 4 main classes of food and beverages, the last of which is represented by the ultraprocessed food group. This comprises products (e.g., snacks, drinks, and ready meals, ‘created mostly or entirely from substances extracted from foods or derived from food constituents with little, if any intact food, which often contain flavors, colors, and other additives that imitate or intensify the sensory qualities of foods or culinary preparations made from foods,’ ” Dr. Bonaccio and colleagues wrote.

Such foods are very convenient, tasty, inexpensive, and have a long shelf life. They are highly competitive with foods that are naturally ready to consume and freshly prepared dishes and meals, the authors add.

The researchers conducted a longitudinal analysis on 22,475 men and women (mean age, 55 years; range, 43-67 years) who were recruited from the Moli-sani Study, a population-based cohort of men and women aged 35 years and older in the Molise region of southern Italy, between 2005 and 2010. Participants were followed for 8.2 years.

Food intake was assessed with the Food Frequency Questionnaire; UPF was defined using the NOVA classification according to degree of processing.

UPF intakes were categorized as quartiles of the ratio of UPF to total food consumed.

Overall, study participants reported a median of 10% (interquartile range, 6.6%-14.6%) of dietary intake as UPF and a total of 181.5 g/d of UPF intake.

The foods that contributed most to total UPF consumed were processed meat, which accounted for 19.8% of UPF intake; pizza (16.8%); and cakes and pies (13.4%).

High consumers of UPF, defined as those for whom UPF constituted more than 14.6% of their total diet, were more likely to be women, to be younger, and to have a higher educational level. They also reported fewer risk factors and fewer baseline chronic diseases and health conditions than persons who consumed UPF less frequently.

In addition, high consumption of UPF was associated with lower adherence to the Mediterranean diet; higher intake of fat, sugar, dietary cholesterol, and sodium; and lower intake of fiber.

During a median follow-up of 8.2 years, 1,216 all-cause deaths occurred. Of these, 439 were attributed to CVD, 255 to IHD/cerebrovascular disease, 477 to cancer, and 300 to other causes.
 

The more UPF, the higher the risk for CVD, death

The researchers found a direct linear dose-response relation between a 5% increase in the proportion of UPF in the diet and risk for all-cause and CVD mortality.

Individuals who reported the highest intake of UPF (fourth quartile, 14.6% of total food) as opposed to the lowest (first quartile, UPF <6.6%) experienced increased risks for CVD mortality (hazard ratio, 1.58; 95% CI, 1.23-2.03), death from IHD/cerebrovascular disease (HR, 1.52, 95% CI, 1.10-2.09), and all-cause mortality (HR, 1.26; 95% CI, 1.09-1.46).

High sugar content accounted for 36.3% of the relation of UPF with IHD/cerebrovascular mortality. Other nutritional factors, such as saturated fats, were unlikely to play a role, the researchers wrote.

Biomarkers of renal function accounted for 20.1% of the association of UPF with all-cause mortality and 12.0% for that of UPF with CVD mortality.

Subgroup analyses indicated that the magnitude of the association between UPF and all-cause mortality risk was greater among high-risk individuals, such as those with a history of CVD or diabetes. UPF was also likely to be more strongly associated with CVD mortality among those high-risk groups.

The interesting finding that the association between UPF and CVD mortality was greater among individuals with good adherence to the Mediterranean diet, which is known to have health benefits, could be explained by the fact that people who may benefit from a Mediterranean diet are more susceptible to losing health advantages when they also include “detrimental dietary behavior,” whereas those who consume a poor-quality diet are less likely to be harmed by an additional unhealthy behavior such as eating UPF regularly, wrote Dr. Bonaccio and colleagues.

“This is an interesting study confirming that consumption of highly processed foods such as pizza, processed meats, and soda are associated with greater risks of cardiovascular disease,” Walter Willett, MD, professor of epidemiology and nutrition, Harvard School of Public Health, Boston, said in an interview.

“These higher risks appear to be mediated in part by high intakes of saturated fat and sugar, but lower intakes of health-promoting aspects of diet also likely contribute to the findings,” Dr. Willett said.

“Some processing of food can be useful for preservation and control of infectious agents, but in general, a diet emphasizing minimally processed fruits and vegetables, whole grains, nuts, legumes, and plant sources of fat will be best for long-term well-being,” he said.

The study was supported in part by the Italian Ministry of Health and the HYPERCAN Study Italian Association for Cancer Research. Dr. Bonaccio and Dr. Willett reported no relevant financial relationships.

Yet another study has linked the consumption of ultraprocessed, or “junk,” foods to bad health outcomes.

In a longitudinal analysis of more than 22,000 men and women from southern Italy, those who consumed the most ultraprocessed food (UPF) had the highest risk for cardiovascular disease (CVD) and all-cause mortality, likely mediated through a diet high in sugar, researchers said.

High consumption of UPF in this Mediterranean cohort was associated with a 58% increased risk for CVD mortality and 52% higher risk of dying from ischemic heart disease (IHD) and cerebrovascular causes, independently of known risk factors for CVD, even among individuals who otherwise adhered to the Mediterranean diet.

The findings “should serve as an incentive for limiting consumption of UPF and encouraging natural or minimally processed foods, as several national nutritional policies recommend,” Marialaura Bonaccio, PhD, department of epidemiology and prevention, IRCCS Neuromed, Pozzilli, Italy, and colleagues wrote. The results were published online Dec. 18 in the American Journal of Clinical Nutrition.

Earlier this year, as reported by this news organization, researchers found mounting evidence that the obesity epidemic and the increase in incidence of related chronic conditions corresponded with an increase in the intake of UPF.

A study that was conducted in a European cohort found that adults whose diet included more UPF and beverages, such as ice cream, soda, and hamburgers, were more likely to develop CVD or die sooner than others who had a more wholesome diet.

As reported previously by this news organization, among adults in France who had a 10% higher intake of UPF and beverages, the rate of CVD, coronary heart disease, and cerebrovascular disease was 11% to 13% higher over a period of about 5 years.

Similarly, university graduates in Spain who consumed more than four servings of UPF and beverages a day were 62% more likely to die of any cause over about a decade than those who consumed less than two servings per day.
 

Where’s the food?

There is very little actual food in UPF. “The NOVA classification provides 4 main classes of food and beverages, the last of which is represented by the ultraprocessed food group. This comprises products (e.g., snacks, drinks, and ready meals, ‘created mostly or entirely from substances extracted from foods or derived from food constituents with little, if any intact food, which often contain flavors, colors, and other additives that imitate or intensify the sensory qualities of foods or culinary preparations made from foods,’ ” Dr. Bonaccio and colleagues wrote.

Such foods are very convenient, tasty, inexpensive, and have a long shelf life. They are highly competitive with foods that are naturally ready to consume and freshly prepared dishes and meals, the authors add.

The researchers conducted a longitudinal analysis on 22,475 men and women (mean age, 55 years; range, 43-67 years) who were recruited from the Moli-sani Study, a population-based cohort of men and women aged 35 years and older in the Molise region of southern Italy, between 2005 and 2010. Participants were followed for 8.2 years.

Food intake was assessed with the Food Frequency Questionnaire; UPF was defined using the NOVA classification according to degree of processing.

UPF intakes were categorized as quartiles of the ratio of UPF to total food consumed.

Overall, study participants reported a median of 10% (interquartile range, 6.6%-14.6%) of dietary intake as UPF and a total of 181.5 g/d of UPF intake.
