Visual deprivation during different developmental periods leads to different structural and functional alterations in the brain; however, the effects of visual deprivation on the spontaneous functional organization of the brain remain largely unknown. In this study, we used voxel-based functional connectivity density (FCD) analyses to investigate the effects of visual deprivation during different developmental periods on the spontaneous functional organization of the brain. Compared with the sighted controls (SC), both the congenitally blind (CB) and the late blind (LB) exhibited decreased short- and long-range FCDs in the primary visual cortex (V1) and decreased long-range FCDs in the primary somatosensory and auditory cortices. Although both the CB and LB exhibited increased short-range FCD in the dorsal visual stream, the CB exhibited greater increases in the short- and long-range FCDs in the ventral visual stream and hippocampal complex compared with the LB. Moreover, the short-range FCD of the left V1 exhibited a significant positive correlation with the duration of blindness in the LB. Our findings suggest that visual deprivation before the developmental sensitive period can induce more extensive brain functional reorganization than does visual deprivation after the sensitive period, which may underlie an enhanced capacity for processing nonvisual information in the CB.

Carbapenemases are beta-lactamases with versatile hydrolytic capacities. They have the ability to hydrolyze penicillins, cephalosporins, monobactams, and carbapenems. Bacteria producing these beta-lactamases may cause serious infections in which the carbapenemase activity renders many beta-lactams ineffective. Carbapenemases are members of the molecular class A, B, and D beta-lactamases. Class A and D enzymes have a serine-based hydrolytic mechanism, while class B enzymes are metallo-beta-lactamases that contain zinc in the active site. The class A carbapenemase group includes members of the SME, IMI, NMC, GES, and KPC families. Of these, the KPC carbapenemases are the most prevalent, found mostly on plasmids in Klebsiella pneumoniae. The class D carbapenemases consist of OXA-type beta-lactamases frequently detected in Acinetobacter baumannii. The metallo-beta-lactamases belong to the IMP, VIM, SPM, GIM, and SIM families and have been detected primarily in Pseudomonas aeruginosa; however, there are increasing numbers of reports worldwide of this group of beta-lactamases in the Enterobacteriaceae. This review updates the characteristics, epidemiology, and detection of the carbapenemases found in pathogenic bacteria.

Prolonged labour causes maternal and perinatal morbidity and mortality. Its sequela include obstructed labour, uterine rupture, maternal exhaustion, postpartum haemorrhage, puerperal sepsis, obstetric fistula, stillbirths, birth asphyxia and neonatal sepsis. These complications can be reduced by using the partograph to assess the progress of labour. The Ministry of Health, Kenya has adopted this tool for labour management in the country and the standardised partograph is recommended for use in all delivery units. Objective: To determine the utilisation of the partograph in the management of labour in selected health facilities in Kenya. Design: A descriptive cross sectional study. Setting: Nine health facilities -ranging from a tertiary hospital to health centre, including public private and faith based facilities in four provinces in Kenya. Results: All facilities apart from Pumwani Maternity Hospital and one health centre were using the partograph. The correct use was low, the knowledge on the use of the tool was average and there was minimal formal training being provided. Staff shortage was listed as the most common cause of not using the tool. Contractions were recorded 30-80%, foetal heart rate 53-90% and cervical dilatation 70-97%. Documentation of state of the liquor, moulding and descent as well as maternal parameters such as pulse, and blood pressure and urinalysis were minimally recorded. Supplies for monitoring labour such as fetoscopes and blood pressure machines were in short supply and sometimes not functional. Overall, the poor usage was contributed to staff shortages, lack of knowledge especially on interpretation of findings, negative attitudes, conflict between providers as to their roles in filling the partograph, and senior staff themselves not acting as role models with regards to the use, advocacy and implementation of the partograph. Conclusion: The partograph was available in most units. However, accurate recording of parameters to monitor the foetus, the mother and progress of labour as recommended was mostly not done. Shortage of staff, lack of knowledge, lack of team work, lack of supplies and negative attitude among healthcare providers were some of the obstacles noted to hamper partograph use.

PIP: In November and December, 1993, a self-administered questionnaire was distributed to men in the town of Machakos and to nonmedical hospital workers of Machakos General Hospital. The purpose of the study was to assess their knowledge about and attitude towards vasectomy. The majority of men were in the age group of 30-44 years and were married; the hospital group was more educated. The town men perceived the pill to be the best contraceptive method for women in contrast to the hospital group who gave more importance to bilateral tubal ligation. The hospital group also perceived vasectomy as the best method for men. Overall, 53.2% men were aware of the correct procedure of vasectomy, but only 24% had correct knowledge of how the procedure affects masculinity. The knowledge of the procedure among hospital workers was not very different from that of the town group. Recommendations were made to increase information and education to all groups of people through various media. author's modified
