[SIGMA]PFCA was calculated by summing the concentrations of the 10 analyzed perfluorinated carboxylates (PFPeA, PFHxA, PFHpA, PFOA, PFNA
, PFDA, PFUnA, PFDoA, PFTrA, and PFTeA).
Mismatch between PFNa

Intramedullary nailing (i.e., PFNA
; Synthes[R] and Gamma Nail; Stryker[R]) and extramedullary fixation (dynamic hip screw (DHS); Synthes[R]) are the two most often performed procedures for treatment.
Intramedullary devices like the DePuy Reconstruction nail (Recon nail), Gamma nail, Proximal femoral nail (PFN), Trochanteric fixation nail (TFN), Proximal femoral nail antirotation (PFNA
) have been reported to have an advantage in such fractures as their placement allowed the implant to lie closer to the mechanical axis of the extremity, thereby decrease the lever arm and bending moment on the implant.
comparing the reverse LISS system with proximal femoral nail antirotation (PFNA
) in the treatment of proximal femoral fractures, although it was emphasised that while early weight-bearing accelerated bone union in the PFNA
patients, the LISS system was reported to be more effective in the prevention of coxa vara of the hip and provided more stable osteosynthesis in osteoporotic patients.
The levels of PFNA
in Paulsboro's drinking water are the highest that have been registered in the United States.
This ethnic difference had been discussed and contributed to the development of the proximal femoral nail antirotation-Asian version (PFNA-II), a modification of the original PFNA

) in elderly Chinese patients," International Orthopaedics, vol.
Monica Lind, associate professor at the Division of Occupational and Environmental Medicine at Uppsala University, said that they saw that high levels, especially of one of the perfluorinated compounds, perfluorononanoic acid (PFNA
), were linked to diabetes.
PFHpA, PFOA, and PFNA
were the main compounds detected in water and melted snow, while PFNA
, PFDA, and PFUnA were the predominant compounds in the aquatic biota, indicating their bioaccumulative potential.
Given the multiracial and multiethnic origins of early Pentecostalism movement, the formation of the first ecumenical Pentecostal Fellowship of North America (PFNA
) in 1948 with no predominantly African-American denominations seems striking.
