Association between first trimester platelet to lymphocyte ratio and stillbirth.

BACKGROUND: Neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (PLR) have been investigated as inflammatory markers of malignancies, cardiovascular and autoimmune diseases. We explored the association between NLR, PRL, measured during pregnancy, and stillbirth (SB). METHODS: We conducted a retrospective case control study at a tertiary hospital center in New York City from May 2015 to July 2018. Cases were defined as SB pregnancies and controls as uncomplicated pregnancies. We calculated NLR and PLR using the complete blood count components routinely collected during prenatal care in the first trimester. The groups were matched by age, parity, body mass index (BMI) and race. We used receiver operating characteristic (ROC) curve analysis to evaluate the association of NLR and PLR to SB. RESULTS: We identified 28 patients with SB pregnancies and matched them with 28 controls. Age, parity, BMI, and race were equally distributed between the groups. The median gestational age of SB was 30 weeks (22-34). In the first trimester PLR was significantly lower in SB cases compared to controls (124.8 vs. 153.4, P=0.044) with an area under the curve (AUC) of 0.65. A PLR value higher than 156.4 accurately excluded SB with a sensitivity of 0.50, specificity of 0.89, positive predictive value of 0.013 and a negative predictive value of 0.998. NLR did not show a significant difference in the first trimester. CONCLUSIONS: A PLR higher than 156.4 in the first trimester appears to reliably exclude the occurrence of SB later during pregnancy. Lower platelet and higher lymphocyte levels may be related to an early inflammatory process. We speculate that pregnancies in which the initial myometrial invasion by the placental cells is dysfunctional and reflected by a high level of inflammation in the peripheral maternal blood, may contribute to fetal demise. Larger studies are needed to confirm our results.

Vertical transmission of Babesia microti, United States.

Babesiosis is usually acquired from a tick bite or through a blood transfusion. We report a case of babesiosis in an infant for whom vertical transmission was suggested by evidence of Babesia spp. antibodies in the heel-stick blood sample and confirmed by detection of Babesia spp. DNA in placenta tissue.

A collaborative approach intended to reduce the duration of short term urinary catheters in adult patients at a tertiary care medical center also significantly reduced the duration of hospitalization.

BACKGROUND: Urinary tract infections are the leading cause of nosocomial infections in the United States. The major contributing factor is the placement of indwelling urinary catheters. METHODS: Following a chart review of adult patients hospitalized at a tertiary care medical center who required the use of a short-term (≤ 2 weeks) indwelling urinary catheter, a collaborative effort was initiated by an Infectious Diseases physician to develop protocols focused on the clinical service involved for the expeditious removal of short-term indwelling urinary catheters. The protocols relied in part on the standards of practice by pertinent medical/surgical subspecialty societies. Usage of urinary catheters and duration of hospitalization following implementation of the protocols was assessed. RESULTS: Based on a multivariate analysis controlling for demographic variables, comorbidities, medical vs surgical service, and indication for the urinary catheterization, the median duration of catheterization was significantly reduced from 6.7 days to 3.6 days after the protocols were initiated (P < .001), and the median duration of hospitalization was significantly reduced from 9.5 days to 5.9 days (P < .001). No patient had to have the urinary catheter reinserted. CONCLUSIONS: Development of collaborative protocols for the removal of short-term indwelling urinary catheters significantly reduced both the duration of catheterization and the duration of hospitalization.

Babesiosis in Lower Hudson Valley, New York, USA.

Although Lyme disease has been endemic to parts of the Lower Hudson Valley of New York, United States, for >2 decades, babesiosis has emerged there only since 2001. The number of Lower Hudson Valley residents in whom babesiosis was diagnosed increased 20-fold, from 6 to 119 cases per year during 2001-2008, compared with an ≈1.6-fold increase for the rest of New York. During 2002-2009, a total of 19 patients with babesiosis were hospitalized on 22 occasions at the regional tertiary care center. Concurrent conditions included advanced age, malignancies, splenectomy, and AIDS. Two patients acquired the infection from blood transfusions and 1 from perinatal exposure, rather than from a tick bite. One patient died. Clinicians should consider babesiosis in persons with fever and hemolytic anemia who have had tick exposure or have received blood products.

Increasing incidence and changing epidemiology of babesiosis in the Hudson Valley region of New York State: 2009-2016.

Babesiosis is an emerging infection in parts of New York State. From 2009 through 2016, there was a significant increase in the incidence rate of babesiosis in the Hudson Valley region of New York State (P = 0.002), an inland geographic location in which babesiosis only first emerged in 2001. A significant increase in cases was found for both the Upper Hudson Valley (UHV) region (P < 0.001) as well as for the Lower Hudson Valley region (P = 0.03). The greatest increase in the incidence rate was found for the UHV, with a 16.8-fold increase in incidence over the 8-year time period. In conclusion, babesiosis is a rapidly emerging infection in the Hudson Valley region of New York State, the geographic region now accounting for more cases than any other single geographic area in the state.
