RESUMO
BACKGROUND: The US population is becoming more racially and ethnically diverse. Research suggests that cultural diversity within organizations can increase team potency and performance, yet this theory has not been explored in the field of surgery. Furthermore, when surveyed, patients express a desire for their care provider to mirror their own race and ethnicity. In the present study, we hypothesize that there is a positive correlation between a high ranking by the US News and World Report for gastroenterology and gastrointestinal (GI) surgery and greater racial, ethnic, and gender diversity among the physicians and surgeons. METHODS: We used the 2019 US News and World Report rankings for best hospitals by specialty to categorize gastroenterology and GI surgery departments into 2 groups: 1-50 and 51-100. Hospital websites of these top 100 were viewed to determine if racial diversity and inclusion were highlighted in the hospitals' core values or mission statements. To determine the rates of diversity within departments, Betaface (Betaface.com) facial analysis software was used to analyze photos taken from the hospitals' websites. This software was able to determine the race, ethnicity, and gender of the care providers. We examined the racial and ethnic makeup of the populations served by these hospitals to see if the gastroenterologists and surgeons adequately represented the state population. We then ran the independent samples t-test to determine if there was a difference in rankings of more diverse departments. RESULTS: Hospitals with gastroenterology and GI surgery departments in the top 50 were more likely to mention diversity on their websites compared with hospitals that ranked from 51-100 (76% versus 56%; P = 0.035). The top 50 hospitals had a statistically significant higher percentage of underrepresented minority GI physicians and surgeons (7.01% versus 4.04%; P < 0.001). In the 31 states where these hospitals were located, there were more African Americans (13% versus 3%; P < 0.001) and Hispanics (12% versus 2%; P < 0.001), while there were fewer Asians (4% versus 21%; P < 0.001) in the population compared with the faculty. CONCLUSIONS: We used artificial intelligence software to determine the degree of racial and ethnic diversity in gastroenterology and GI surgery departments across the county. Higher ranking hospitals had a greater degree of diversity of their faculty and were more likely to emphasize diversity in their mission statements. Hospitals stress the importance of having a culturally diverse staff, yet their care providers may not adequately reflect the populations they serve. Further work is needed to prospectively track diversity rates over time and correlate these changes with measurable outcomes.

BACKGROUND: Establishment of persistent human immunodeficiency virus type 1 (HIV-1) reservoirs occurs early in infection, and biomarkers of infected CD4+ T cells during acute infection are poorly defined. CD4+ T cells expressing the gut homing integrin complex α4ß7 are associated with HIV-1 acquisition, and are rapidly depleted from the periphery and gastrointestinal mucosa during acute HIV-1 infection. METHODS: Integrated HIV-1 DNA was quantified in peripheral blood mononuclear cells obtained from acutely (Fiebig I-III) and chronically infected individuals by sorting memory CD4+ T-cell subsets lacking or expressing high levels of integrin ß7 (ß7negative and ß7high, respectively). HIV-1 DNA was also assessed after 8 months of combination antiretroviral therapy (cART) initiated in Fiebig II/III individuals. Activation marker and chemokine receptor expression was determined for ß7-defined subsets at acute infection and in uninfected controls. RESULTS: In Fiebig I, memory CD4+ T cells harboring integrated HIV-1 DNA were rare in both ß7high and ß7negative subsets, with no significant difference in HIV-1 DNA copies. In Fiebig stages II/III and in chronically infected individuals, ß7high cells were enriched in integrated and total HIV-1 DNA compared to ß7negative cells. During suppressive cART, integrated HIV-1 DNA copies decreased in both ß7negative and ß7high subsets, which did not differ in DNA copies. In Fiebig II/III, integrated HIV-1 DNA in ß7high cells was correlated with their activation. CONCLUSIONS: ß7high memory CD4+ T cells are preferential targets during early HIV-1 infection, which may be due to the increased activation of these cells.

Several studies in recent years have already reported good oncologic results with laser microsurgery in the treatment of early glottic carcinoma. We conducted a longitudinal voice evaluation, in patients with early glottic cancer who underwent transoral laser cordectomy, in order to assess the voice quality outcome and its relationship with objective and subjective (voice handicap index questionnaire and GIRBAS scale) means. Twenty-four previously untreated patients underwent transoral laser cordectomy for early glottic cancer. All patients underwent subjective and objective voice assessment according to the multidimensional voice protocol recommended by the European Laryngological Society including acoustic, perceptual and stroboscopic analysis combined to patient self assessment of voice (voice handicap index-VHI). These evaluations were performed before treatment and 6 months after the treatment. Vocal fold healing was complete in all cases by 6 months following surgery. Main voice parameters (subjective and objective) resulted improved at the 6-month control after surgery. In particular, voice handicap index (VHI) and GIRBAS scale resulted reliable for voice assessment and for the postoperative follow-up. In conclusion, VHI, GIRBAS, multidimensional voice program (MDVP) and spectroacoustic parameters showed a close trend in the present study, and this confirms the validity of the voice analysis performed by each tool.

Regulatory T cells (Tregs) play important roles in tissue homeostasis, but few studies have investigated tissue Tregs in the context of genital inflammation, HIV target cell density, and vaginal microbiota in humans. In women from Nairobi (n=64), the proportion of CD4+ CD25+ CD127low Tregs in the endocervix correlated with those in blood (r=0.31, p=0.01), with a higher Treg frequency observed in the endocervix (median 3.8 vs 2.0%, p<0.0001). Most Tregs expressed FOXP3 in both compartments, and CTLA-4 expression was higher on endocervical Tregs compared to blood (median 50.8 vs 6.0%, p<0.0001). More than half (34/62, 55%) of participants displayed a non-Lactobacillus dominant vaginal microbiota, which was not associated with endocervical Tregs or CD4+ T cell abundance. In a multivariable linear regression, endocervical Treg proportions were inversely associated with the number of elevated pro-inflammatory cytokines (p=0.03). Inverse Treg associations were also observed for specific cytokines including IL-1ß, G-CSF, Eotaxin, IL-1RA, IL-8, and MIP-1 ß. Higher endocervical Treg proportions were associated with lower abundance of endocervical CD4+ T cells (0.30 log10 CD4+ T cells per log10 Treg, p=0.00028), with a similar trend for Th17 cells (p=0.09). Selectively increasing endocervical Tregs may represent a pathway to reduce genital tract inflammation in women.

A case of subcutaneous sarcoidosis involving the paralateral nasal region is described and a brief review of the literature is made. Subcutaneous sarcoidosis without systemic disease is a rare entity and has seldom been reported on the trunk and face. Diagnosis is always difficult as it can only be confirmed by histological studies.
