Background: SPECT/CT distribution patterns in patients with total knee replacements have previously been correlated with factors such as time of implantation, implant type and alignment. It is unknown, however, if an increased and more extended bone tracer uptake (BTU) in SPECT/CT, representing loading of the joint, correlates with findings from retrieval studies. The aim of this study was to further understand this subject. Materials and Methods: 62 retrieved TKA were included. SPECT/CT was performed prior to revision. Quantitative and qualitative medio-lateral comparisons of BTU intensity and distribution in the tibia were performed. Retrieval analysis was performed with a micro-CT method to assess the thickness differences between medial and lateral sides of polyethylene inserts with symmetrical designs. Results: In the subgroup of TKA with asymmetrical SPECT/CT distribution, there was a significant correlation between retrieval and medical imaging data (p = 0.0355): patients showing a more extended BTU in the medial compartment also had a significantly thinner insert in the medial compartment, and vice versa in the lateral side. Conclusion: This is the first study comparing BTU distribution patterns and retrieval findings. Our results support the hypothesis that SPECT/CT is able to identify bone activity due to implant position and loading.

Pendahuluan : Difteri adalah suatu infeksi yang disebabkan oleh bakteri Corybacterium diphteriae, yang menyerang selaput lendir pada hidung dan tenggorokan, serta dapat mempengaruhi kulit. Penyakit ini sangat menular dan termasuk infeksi serius yang berpotensi mengancam jiwa.Tujuan : Penelitian ini bertujuan untuk menganalisis pola distribusi kasus difteri di Kabupaten Bojonegoro pada tahun 2009– 2019 (Agustus 2019).Metode : Penelitian ini dilakukan pada tanggal l5 Agustus-18 September 2019 di Kabupaten Bojonegoro. Penelitian ini adalah penelitian deskriptif dengan menggunakan data sekunder berupa laporan bulanan kasus difteri yang dilaporkan oleh Puskesmas atau Rumah Sakit di Wilayah kerja Dinas Kesehatan Kabupaten Bojonegoro dan hasil wawancara dengan Kepala Seksi Surveilans dan Imunisasi, serta Penanggungjawab Program Surveilans Difteri di Dinas Kesehatan Kabupaten Bojonegoro.Hasil : Hasil penelitian menunjukkan bahwa berdasarkan usia kasus difteri di Kabupaten Bojonegoro tertinggi terjadi pada kelompok usia 5-9 tahun (29,16%). Berdasarkan jenis kelamin sebagian besar terjadi pada jenis kelamin laki-laki (61,84%). Berdasarkan status imunisasi, kejadian difteri terjadi pada kelompok usia < 1tahun. Berdasarkan tempat, kejadian difteri di Kabupaten Bojonegoro sering terjadi di Kecamatan Bojonegoro. Berdasarkan waktu, kejadian difteri terjadi pada periode Januari-Maret dan Agustus-Desember.Kesimpulan : Kasus penyakit difteri di Kabupaten Bojonegoro dari tahun 2009 sampai dengan Agustus 2019 cenderung fluktuatif. Pada tahun 2009 hingga tahun 2012 kasus difteri di Kabupaten Bojonegoro mengalami peningkatan yang signifikan dan mengalami penurunan di tahun 2013 dan 2014. Kemudian pada tahun 2015, kasus difteri mengalami peningkatan kembali dan penemuan kasus terbanyak ada di tahun 2018 yaitu sebanyak 15 kasus.Penderita difteri paling banyak adalah anak usia 5-9 tahun yaitu sebanyak 21 anak. Beberapa penderita difteri memiliki riwayat imunisasi yang tidak lengkat maupun yang tidak pernah imunisasi sama sekali. Sedangkan penemuan kasus difteri terbanyak sering terjadi pada laki-laki.ABSTRACTBackground: Diphtheria is an infection caused by the Bacterium Corybacterium diphteriae, which attacks the mucous membranes of the nose and throat,then can affect the skin. This disease is very contagious and includes serious infections that are potentially life-threatening. Objectives: This study to analyze the distribution patterns of diphtheria cases in Bojonegoro Regency in 2009 - 2019 (August 2019). Methods This research was conducted on August 5-September 18, 2019 in Bojonegoro Regency. This research is a descriptive study using secondary data in the form of monthly reports of diphtheria cases reported by Puskesmas or Hospitals in the Work Area of the Bojonegoro District Health Office and the results of interviews with the Head of the Surveillance and Immunization Section, and the Person in Charge of the Diphtheria Surveillance Program at the Bojonegoro District Health Office. Result: The results showed that the highest age of diphtheria cases in Bojonegoro District occurred in the 5-9 years age group (29.16%). Based on sex, the majority occurred in male sex (61.84%). Based on immunization status, the incidence of diphtheria occurs in the age group <1 year. Based on location, diphtheria events in Bojonegoro Regency often occur in Bojonegoro District. By time, diphtheria events occurred in the January-March and August-December periods. Conclusions: Cases of diphtheria in Bojonegoro Regency from 2009 to August 2019 tended to be volatile. In 2009 until 2012 diphtheria cases in Bojonegoro Regency experienced a significant increase and decreased in 2013 and 2014. Then in 2015, diphtheria cases increased again and the most cases found were in 2018 which were 15 cases. The most diphtheria sufferers many are children aged 5-9 years, as many as 21 children. Some diphtheria sufferers have a history of immunizations that are not complete or have never been immunized at all. Whereas most cases of diphtheria are often found in men.

The analysis of the distribution patterns presented by examples of freshwater fishes restricted to headwater habitat: the anostomid Leporinus octomaculatus, the characins Jubiaba acanthogaster, Oligosarcus perdido, Moenkhausia cosmops, Knodus chapadae, Planaltina sp., the loricariid Hypostomus cochliodon, and the auchenipterid Centromochlus sp. provided evidences of a relatively recent shared history between the highlands of the upper rio Paraguay and adjoining upland drainage basins. Restricted to headwater of the uplands in the upper rio Paraguay and adjoining basins, these species provide biological evidence of the former extension of the central Brazilian plateau before the origin of the Pantanal Wetland. Disjunction took place due to an ecological barrier to these rheophilic taxa represented tectonic subsidence related to the origin of the Pantanal Wetland. Molecular analysis of Jubiaba acanthogaster revealed that the sample from the upper rio Xingu basin are the sister-group of a clade that includes samples from the upper rio Arinos (upper rio Tapajós) plus the upper rio Paraguay basin, supporting the assumption that the origin of the upper rio Paraguay basin causing vicariance between this basin and the upper rio Tapajós is the least vicariant event in the evolutionary history of the group.

A knowledge of life cycle and natural history are often important prerequisites to studies of population biology in butterflies. Although studies on the systematics and broad distribution patterns of that familiar New World Tropical group, the Ithomiinae, have been conducted (Seitz, 194; Fox, 1956; Fox, 1968), a lot remains to be known about the biology of many species in Central America. This is surprising in light of the considerable interest in these butterflies as members of mimicry complexes. In this spirit, this paper summarizes life cycle and natural history data on a clear wing ithoreiine Hymenitis nero (Hewitson) (Nymphalidae: Ithomiinae) in Costa Rica. Similar studies of several other sympatric ithomiines have either been completed (Young, in prep.) or begun, as a preliminary step towards understanding the local patterns of diversity of this family in selected tropical plant communities.
